Halfway to wits end on 420

[cNd]

I have been reading for 2 solid weeks and am searching and have read every post back to mid summer (in this forum) and have absorbed so much that I am now a "half wit".

I have a dual chip 420. I built the J-tag from unwink, I built Mega-volts J-tag, both are buffered and seem to work partially.

I tried the 25 pin deal with an old printer cable, a cat5, ribbon cable, cat5E, a printer cable IEEE, tried cutting the end off and going directly to my J-tag, and finally it works fairly good with the cut-off IEEE.

My results are missing channels (some, not all), and I do know how to write an activation file.

There has to be something I am doing wrong.

I have a valid P5 card so I have a good number to use.
I have it on my HU - no problem.
I used the file from un-wink for a dual chip Unwinked for the flash, and my bin with the new # and activation file for the EEprom prog. It is the same as on my HU. Didn't work well. Very few channels and remote didn't work.

Did the same thing with the dual chip winked (from un-wink) and basically the same results except the now it comes in on channel 4 instead of 3 on my TV.

I found a fix for the remote (thanks go to Dungeon) by pressing the "aux" button on my remote. Now at least it works.

I have been using the latest "J-keys".

I cut the trace and installed a write protect switch. It works great.

I understand about the bfr to grd. for boot from link. It works.

I installed pins for TDO< TDI< ect so I can use a short ribbon cable (4") to hook the J-tag up.

I have tried +5v, and +3.3v with no difference that I can see.

I've tried everything and I know that by now I am overwhelmed with a whole lot of info that does not pertain to the 420.

I don't want someone to do it for me, but I would appreciate a little direction starting after my j-tag is hooked up.

My J-tag is hooked up, the bfr is grounded, the power is on to the J-tag, the J-tag is hooked to the parallel port, and J-keys recognises it.
The write protect switch is in the +5v stage which means it is ready to erase and flash.

HELP.

Missing channels, go into the profiles section of setup and be sure they are all enabled.....change the out put back to channel 3 and the remote to DTV while you are in setup.

i remember posting this. search button, the almighty search button

[cNd]

I to believe in the almighty "SEARCH" icon. If you will notice in my original post I wrote that I had read and searched for quite a while, learned a whole lot, most of which wasn't aimed at my specific 420 problem, and was reasonably confused and begining to mix what worked on one model was different than on another. I was convinced that it had to be a software problem or something was amiss with my J-tag(s).

I wasn't thinking along lines that it may be an internal ird adjustment. I finally asked for help and skinerd saw what I had tried - figured out what my problem probably was - and replied.

Had I not included in my original post the amount of work I had already invested - I would have expected a "search button" comment. In fact I probably would have said the same thing, and have on many ocassions.

Better than half of the 6 months of threads I read never came around full circle from the original question to the final fix. The threads are left dangling and many times after reading them, you aren't sure if the problem got solved or forgotten. People do not return and say "Yep, that fixed it" Or a simple "thanks for your help". Some people do answer and those threads are the ones to learn from. We need more of them.

Enough ranting - I just felt that I earned a question. Still do.
