Headache of a 430

[zhakrin]

I am having a splitting headache with this 430 RG


Before i cut the trace on it i had the jtag installed, working fine and i managed to do a read of the flash and save.

After i cut the trace and followed the unwink instructions the jtag interface isn't working, i even tried reconnecting the cut trace using a wire.

When i get the programmer to register at all it is comming up with an "Error Reading from IRD (DCU Peek)"


IT is reading the device ID as 0x1D405041 and the device as STi5518MVB-X.

I just pulled the BFR to ground wire and when the reciever powers up now the power LED comes on and will not shut off.

I used a ohm meter to check the power from before the cut trace to pin #2 on the ST chip and i do have power through.

Any ideas would be appreciated.


Zhak.

[zhakrin]

It looks like it was a software problem, i put the reciever in the stream for an hour or so and it came back up normally.

I managed to program it with the latest no-zkt 430 flash from dssftp and everything appeared fine .. until...


Despite having a signal lock at 90% it is comming up "Searching for Signal"


Zhak

[skinerd]

Did you write protect the flash??
if not it may have become corrupted,
reflash and try again......

[zhakrin]

To fix the problem i reconnected the cut trace and plugged it into the datastream.

The light stayed on for a while, and i was able to shut it off (with a severely delayed reaction time aka minutes) after a while the reciever started turning itself off and on.

I can only assume that the flash was somehow corrupted and the time in the datastream fixed it.

Don't know how much this will help but I don't argue with what works.


Skinard, i am going to reflash it again and see what happens, i am also going to see what hapens when i reinstall the original read.

Is there a complete virgin dump available someplace that i can also try writing to the chips? Is there data in areas other then the standard range that jkeys writes for the 430 that may have gone corrupt that i can replace?

Since i am getting 90% signal from the setup screen can i assume that I havn't burnt any hardware?

[zhakrin]

i have the intel e28fj320j3a110 chip

[zhakrin]

i would be even luckier if i could get the daqmb thing to detect the satelite signal. still 90% locked signal strength but can't detect the satelite for pulling up the channels

[skinerd]

If the flash is wrong or corrupted you will get this error, try reflashing. Flash can be come corupted many ways, even while writing to it.........

[zhakrin]

I just did a read of the flash from my reciever and used Hex Workshop to compare it to the DRD430ANoZKT bin file. They are comming up identicle.

Is the flash the only thing that can be causing this or is there something else i should be looking into?

It just seems strange that everything else works perfectly, including testing signal strength.

Zhak

[skinerd]

http://www.dssftp.com/filedownload/category.php?category=8 ......4th on the list try it.........

[zhakrin]

Just applied that BIN and read it back off the chip and compared it to the original file.

Its a good wirte but the reciever still no work.

[zhakrin]

I was just looking over at Mr. White's jtag site, he has a info sheet on 'searching for satelite' errors in which he reccomends replacing a
zenor diode and tip 42 transistor.

Is there any way to test if this is needed or not? since i have a lock at 90% signal strength I was thinking the hardware was all good.


The instruction file is here: http://www.mrwhitesjtag.com/files/Instructions/Searching%20for%20Sat%20Signal%20Guide.zip

[skinerd]

90% signal means hardware is fine........it's more than likely a flash problem..............

[zhakrin]

I was thinking since i am having such trouble with the flashes, does anyone out there have a pre-november update flash that i could install onto this IRD and attempt to let it take an update from the stream?

I have the backup i made when i first started but due to the fact that i was having jtag 'adventures' with my hookup at the time i am finding it to be an unreliable read.

Any help would be mouchos appreciated, even if i can't get this reciever NO-ZKT moded my buddy would really llike it back at least functional.

use the latest flash it works fine.........

one thing to check is the multiswitch setup in system setup, let it auto detect..........I had a 450 do that to me, stayed SFS until I ran that auto-detect.

I ran the auto-detect and it came up 'error, can't detect anything' or some such. The reciever is plugged directly into the dish, no joints, spliters or anything. Just one 30ft cable.

[skinerd]

I don't know what else to tell you............

zhakrin:
i to have run into this problem while doing the nozkt on 430's. usually when i recieve "Error Reading from IRD (DCU Peek)" i just unplug the power cable from the wall, leave jtag all hooked up, restart jkeys and reciever in boot from link mode, then it allows you to go again. It seems that once you start and something goes wrong you have to completely restart the process. unplug, bootfromlink etc. this seems to have worked for the430,s i have modified. good luck

[zhakrin]

Skinard, I am pretty much at a loss too, all hardware seems to check out and i get great signal quality in the dish pointing screen but no matter what flash i have installed i get the same problem, i have installed every single 430/431 flash i have found ANYWHERE on the net and have yet to get it working properly, i even tried leaving it in write-enable mode plugged into the datastream overnight and I am still S.O.L.

I really appreciate all the advise you have been giving me on things to try, if you ever get talking with any of your friends who are heavy into this stuff and get a chance to see if they have ever fixed a problem like this i would appreciate it. I am pretty much grasping at straws atm in the way of a solution so anything you can think of, no matter how crazy is appreciated to try.

Yup, managed to get around that problem I am just stuck with a searching for satelite with over 90% signal strength problem now.

Yup, managed to get around that problem I am just stuck with a searching for satelite with over 90% signal strength problem now.

I've heard that before but never saw it myself.
Searching for satelite signal used to be caused by wrong flash.
Ie: puting pre november/2002 based flash on 430RGA.
Flash is good not corrupted but receiver can't pass "searching for signal"
phase.
Make sure that you have latest post november flash.
nozktdrd430A_2_04.zip
Worked for me.

Ps I just did Phillips DSX5350 , they're very cheap and
ITS WALK IN THE PARK , compared to 430RG (especially with ST28W flash).
I could do 5 phillipses in time it takes to do one RCA.
May consider buying one.

[zhakrin]

i'll take another crack at it when i get home, I can honestly say this i am going to be a 430 expert soon at this rate With all of the web page reading, circuit tracing and such that I have been through i have that circuit board engraved in my brain

[zhakrin]

Since i have had absolutely no luck with any single 430/431 flash available on the net that i can find does anyone have a copy of a virgin flash of pre-november update flash that may be compatable with this reciever for me to try, maybe if it takes the flash update from the stream it will work <shrug, i'll try anything at this point>

I know i have heard of people changing reciever menues to hughes and others by flashing them in, maybe one of those would get this thing up and running. Are there recever flashes compatable to this 4 meg flash chip that will work in the 430 RG?


Zhak

[skinerd]

I have several 430 flashes that I could send you, I don't know which are virgin pre-update tho. PM me an e-mail addy if you want them.....

[zhakrin]

check your pm

[rush]

zhakrin i have a 430 that has never be mod and it has the same problem as yours .iv done some serching and reading to come to the conclusion that the LNB chip in the reciever is shot they are available but very hard to soder one in..........

[skinerd]

I sent him a virgin flash, have not heard if it worked or not..........

[zhakrin]

took a night off from this reciever last night (wife was getting a little ... unpleasent)

I'll be trying it out tonight and let y'all know.

[skinerd]

I have the 430 with the ST flash (28W320CB). I was able to successfully solder to the JTAG terminals and save both the flash and EEPROM, but I have not been able to erase any part of the flash. Furthermore, I used JKeys 2.9.10, selected Flash 3 (28W320CB), and tried to program the flash without erasing. At first, it acts like it is working, but then gives the error. I then hooked it back up to the TV and I still get the 745 nag.
I think I cut the correct trace that is located just in front of the transistor switch. I also soldered a 3.3V source to the transistor switch and tried the whole procedure over again---no dice. Then, I soldered the 3.3V source directly to the Emitter of the transistor going to the ST flash chip---still no dice.
I have since downloaded the datasheet to the 28W320CB ST flash chip.

Any suggestions or ideas on how to test if the flash can be erased?

Did you even bother to read or search ?? There is a lot of info if you will look.


http://www.dssftp.com/forum/upload/...ight=%2Am28W%2A

http://www.dssftp.com/forum/upload/...ight=%2Am28W%2A

[skinerd]

If you have the data sheet, you could solder to the flash directly, just be sure to solder to the correct pin, you can just solder a wire from there to 3.3v or 5v and that will enable the chip, but you should also cut the trace leading from the flash to the transistor.

If you would have done some reading first, I have posted a better place to cut the trace and apply 3.3v to enable these chips, it is really a lot easier that what anyone else shows........

You will still have to unlock all 71 sectors maunally tho........

[zhakrin]

Just installed the flash you sent me and still no go same problem of 'searching for satelite signal' despite the fact that everything appears to be good on it.

I just logged into the Service menu and ran a service test and it appears to check out ok so i am still confused as heck, here's the report from it:

Do you have another eeprom file thay you could put in it to try??

[zhakrin]

Do you have another eeprom file thay you could put in it to try??

yea, i have one here i downloaded from mrwhitesjtag suposidly a virgin 430 eeprom.. guess i should back up mine first, isn't that where the reciever stores the serial number?

if you have one handy, shoot it over to that email addy i created, eeproms are small files i think.

just wrote on that eeprom, and still go go.

[skinerd]

with all the problems you have had with this one, I went back and read all the posts in this thread, seems to me it has got to be a corrupted flash.
Have you tried another PC?? Shortening jtag leads??
Something may be causing your writes to become corrupted, it worked before you started, and your signal strength is good, it's not hardware.

[zhakrin]

I am 100% stumped on this one, my jtag leed is something like 10 inches atm, i am not useing the normal 3ft parallel cable i use when programming, just a shoirt ribbon cable with the jtag plugged directly into the PC. Hell i have reinstalled the solder leads at least a half dozen times to boot.

I have tried programming the flash, the reading it back in and running a compare against the original file and the have come back 100% matched. Quite frankly from everything that i have seen there is absolutely NO reason whatsoever that this should be happening.

To be honest, i would just scap this thing but i am so darn curious about what is causing the problems i just can't let it go. Hell recievers can be had for 40 bucks on eBay atm, its not the money that the reciever is worth, its my curiosity and NEED to know.

Btw i really appreciate all of your help with this, it seems to have even some of the best stumped.

[zhakrin]

zhakrin i have a 430 that has never be mod and it has the same problem as yours .iv done some serching and reading to come to the conclusion that the LNB chip in the reciever is shot they are available but very hard to soder one in..........


Would i get the 90% signal strenth from the dish pointing if the LNB chip was shot?

[rush]

if you are getting a 90% signal than your LNB chip should be fine.....

Just out of curiosity, did you try to reboot the ird and plug it back
WITHOUT the cam?

[skinerd]

I ran the auto-detect and it came up 'error, can't detect anything' or some such. The reciever is plugged directly into the dish, no joints, spliters or anything. Just one 30ft cable.

Then it is set for no switch correct??

Go into dish pointing and check odd and even transponders, make sure that you are getting a good signal on both odd and even........
Let me know, I am curious as to what's going here also.....

[rush]

yes i did and when i checked for signal strenght i had a 0 reading on that 430 i tested another ird for signal andgetting reading in high 80%..

[lefty]

Just installed the flash you sent me and still no go

Have you looked at ALL the SM chips to check for fine little solder balls that may have found thier way into a couple of places? Have you triple checked the cut traces to be sure you didn't cut the wrong trace?
Who's instruction set did you go by when doing the mod? Mili's. Unwink's, or skinerds? They all work, but each has subtle differences. Have you tried another LNB? Measured that voltage, etc? Does another IRD work fine on that LNB/cable combo?

I just logged into the Service menu and ran a service test

How do you get to that screen? I don't see it in the menus.



:cool:

[skinerd]

Skinerd..would you please verify me the cut and where to solder the 3.3v or 5v for the write enable chip M28w320.
1.cut the same trace as 430 with 29w? if yes..where do i solder the wire to supply the 3.3 v?..let say if the pin 1 (dot) is at upper left, the cut trace should be about above center of chip...right. Now do I solder the wire to the cut on the left trace or the right trace? It has been a month...and 100 of manually typing 71 blocks...I'm about to give up...thanks.
2.if looking at the flash, and pin 1 (dot)


It is best not to solder a wire to the flash and should be done as a last resort. Did you see my pics on where I cut and apply the 3.3v?? They are the same for ALL 430 type IRDs.

[skinerd]

BugMan1...what is the outcome of your IRD? all done? I've been trying to mod this IRD for a month and still haven't got it to work. don't know if I mistyped or what...but typing over 100 times or 71 blocks. If you have the data sheet of this 28W320CB chip. Could you please tell me what is the write enable pin number is? I want to apply 3.3v directly to the pin too. Thanks.


If you must it's pin 14.

[skinerd]

Before doing any un-doable damage, be certain what you are soldering to.....

its similar to the reset instructions except you hit the left arrow, right arrow, info button.

To be honest i found it by accident when resetting a reciever in the dark and hit the wrong buttons.

Zhak

[zhakrin]

Just out of curiosity, did you try to reboot the ird and plug it back
WITHOUT the cam?


Yes, if there is no card i get "Please insert Access Card" if there is a card in the reciever I get "Searching for Satellite"


Zhak

[alkasecond]

Zhak

Take the card out of ird ,unplug it and plug it back.
Reboot once more.
Does the ird pass the "searching for satelite signal" phase or not?
It may take couple of minutes.

[zhakrin]

I have a 430rga and its doing the same thing. But i thought when you get a "searching for satellite signal" the lnbp15sp chip maybe going bad. But I can't find that chip anywhere on the board. So anybody have ant tip I'm willing to try also.

Oh yea, I also get 90 on the signal but when i measure sat in on the receiver i get 0 volt.

Thank-you.

when looking at the board turn it so the OMEGA ST chip's writing is the correct way up (rear of the reciever facing you) then look to the left about 2 1/2 to 3 inches and down about a half inch for a chip with 5 pins on the top and bottom.

Zhak

[zhakrin]

I get 13/18 volts on the satelite in coax socket

How is it possible to have a 90 signal with zero volts????
Are you sure you are measuring correctly.????

The 430 RGA does not have a lnbp15sp, it is a newer improved version of the 430..........

[skinerd]

Not to beat a dead horse, but I have two questions.

1.) When trying to unlock the 71 sectors on a 430RG, I know you're supposed to type in 60, Write Byte, D0, Write Byte. However, in JKeys, there is a Write Word also. Can you type in 60D0 and then hit Write Word?

2.) Is there a way to verify that each sector is unlocked, like a difference in the Read Byte before and after you unlock the sector? Maybe, this way I can verify that each sector is unlocked before I go any further.

1.) Yes I have used the write word insted of write byte and it worked the same.........

2.) I don't know how to check. I made a macro program that unlocks them for me, only had to do it twice to get it right. Now I unlock them with minimal effort. One note, if you mess around and try to read anything, you will wind up relocking them.......I found the best thing to do is to save everything that you want, then reboot receiver, restart jkeys, unlock sectors, then erase and reflash without doing anything else, otherwise they will relock.

[skinerd]

I have sent my macro to other and they could not get it working, it is a recorded macro, using mouse movements and I guess it is specific to my setup.

The addresses I posted are what I use , without problems.........the data sheet gives them as offsets, but you have to know the base address of the application then apply the offsets.

[skinerd]

example the data sheet says block zero starts with 000000, but the base address is 7FE0000, so the next adres begins with 001000, added to 7FE0000 would be 7FE1000, understand??

[skinerd]

No, you must start at the base address of the application.

[skinerd]

BugMan,
who's method did you use to cut trace and apply thr 3.3v did you use??
I went thru the datasheet and it seems as there is a way to tell what value Vpp is at, but without a 430 w/M28W on hand for me to try, I can't say that I am sure of the address to read, if you think you have it figured, use flash programming to read a single location and see.....

[skinerd]

trace to pin 14 runs under the chip

[skinerd]

I'm lost on this now, I don't know what you have cut and what you have hooked up......I think Vpp is switched by the processor during write/erase proccedures. The jtag actually is hooked to the STi processor and some of the commands and switching are done by it.

[Tom James]

I am having a similar problem to the rest of you in this thread, I am
modding a DRd431RG receiver with an Intel chip. I have done the flash
several times with the same results, never leaves searching for sat.
signal. I do not have any signal level, but I do have the 13v and
18v at the sat in connector. My test results are almost the same as
Skinerds except my ROM is 00390204M000B0105. My Demod Signal is
0,CX,LNB OK and my EEPROM is OK/21D6/0012/00. I beleive I used Skinerds
hookup and his latest bin. I wondered a why my ROM was a bit different.
Any help would be welcomed.

[skinerd]

Tom, you used the flash bin from dssftp?? the 4th on the file list for nozkt mods??

[zhakrin]

Just got a replacement 430RG in for my buddy and did the mod in about one hour.

This original reciever is still driving me nuts though.

One thing i noticed on the new 430RG (and now that i think about it on the old one, pre-mod) i get a screen when it boots up "Aquiring guide information" which runs up to 100% before you can do anything with the reciever and takes a minute or 2 to do. The reciever does this whether i have it hooked up to the dish or not. My problem reciever isn't doing that.

I am not sure what that means, but hoped someone might.

[Tom James]

That is correct,the one that you suggested. Should my ROM not have come out the same as yours?

[skinerd]

That is correct,the one that you suggested. Should my ROM not have come out the same as yours?


I don't know about the ROM differences, and I don't have 2 430s to plug in and check............only have 1....

[skinerd]

skinerd, where does the trace go to next from pin 14? I'm trying to locate the source of the constant 3.3V on that pin. Is there a schematic for the 430; like the 420?

Also, are there any other tools for sending and receiving data to the JTAG programmer? I've always used Hyperterminal for serial comm, but I don't know jack about parallel com. Any tutorials?

I have searched for a 430 schematic, none to be found......
the trace goes under the chip, I have never followed it thru....but I think it goes thru the board, across the bottom a short distance then back up to the top and to the current amp.

The 430 goes to that aquiring data as soon as it detects a signal, I have never seen one do that with out being hooked to a dish tho....I don't know why it takes so long, or exactly what data it is aquiring, but they all do it normally, the 430s and up that is...
Have you tried writing an eeprom from a good IRD to the problem one??

Well my 'problem' one doesn't do it, ever. I will try loading the eeprom from the new dish onto it this weekend and see what happens. I was so happy last night when the replacement 430 started working without a hitch that I said 'screw it' for the night.

[skinerd]

Try the aux or sat 2 button and if that works go into setup and change it back.
