removing internal chip, unlocking and reading

[eevo66]

with mikn2 and reading with our iso's. is it possible? is there a card that will hold the chip to go into the mikobu or iso? does anyone know a way to remove the card and unlock and read it externally?
if there is a card that can be purchased to do this where can i get one? i dont see one in the store here (or maybe im not seeing it here) what is it called?
any help?
thanks in advance

Mili used to have them they were called X1's i had the joy of using one, it worked slick, drop chip in there and solder it. very easy very nice. he sold out of them and i dont know if he is getting anymore. What you ask can be done, a heat gun is used to get chip off. then you can mount it on anything, even a old rom 3 card or a old avr x a old magic card, anythign can be used to make it work. now newer eeprom revisions are more likely to loop than older ones trying to unlock

i want to remove the card unlock it read it put the info on another card and leave the original chipset the way it is now. wire the card slot and watch hidef on my 811, if at all possible i want to use a atmega with that info more than anything. do u think there is a way to have the chip held with a sim card holder? i have a credit card size sim card holder only the openeing is bigger than the actual chip. has anyone done that b4?

In this thread, I posted a couple pics where I mounted a 311 chip on old atmega boards...you can use anything that will fit into card slot.

Nice work on that atmega skinerd, i now have another question. why do u need to do any wiring, there arent any wires on a rom 2 card, , how did u get the chip out of the atmega? i have a bunch of old rom 3 and 10 cards even rom 11 just to be sure do i use a heat gun from the opposite side of the chip, i think i want to remove the chip from 1 of the old cards and replace it with the internal chip. how much heat do i apply, how does the chip come out i see it is thin and looks like it will bend and mutilate easily..

The atmega was stripped by heating with a hot air gun, (that was done back when atmegas were said to no longer work, they do now).

The chip was removed from a 311 same way, a hot air gun from topside. Get it hot so you can lift it with needle nose pliers. Takes a couple minutes, my hot air gun gets HOT.

I don't know about that, to me a 811 is as easy as a 311, you can, in either case, solder wires directly to the place where the chip was. Then add a dab of glue to help hold the wire in place.

I have been sent 811s that were pretty messed up, to the point the guys gave up, and I have got every one working.

thank you guys for all the good info and replies. my idea is to activate the card slot, wich is easier???.... interface board to read the info on the 811 or remove the chip? it seems to me the chip might actually be easier but i havent looked at it yet either. in any case, my idea is to read the info on the internal chip, activate the card slot and load info for a atmega for now,as long as atmega works i wanna use it.

[skinerd]

If it was me, I'd pull chip, wire card slot and put chip on a BGA board and use it..if you can glitch it open to read it, which will have to be done in any case.

[skinerd]

not trying to say your wrong, its easy for some your way: but for a novice especially since there very fragile(lil solder balls) and especially a 811 everything is so close to bga chip, not like a 311 enough heat to remove chip nearly always seems to remove other things as well. and direct solder to loader to connection points on chip is far easier and more durable, remember bro most people dont do several a week like us and a newbie especially will be destroying a good ird, i think at anyrate a onboard glitch should always be tried first..DVD..

Problem with onboard glitching is the numerous trace cuts, (or component removals) that need to be made to isolate the chip. Not exactly novice friendly either.

dvd? what makes u think im a novice/newbie? i might work on circuit boards all the time, i have never taken out a chip however i have pretty good solder skills and can read many schematics. not good at rerading them but in any case i can read them. i understand what ur saying about heat and things close together, im just a bit offended that you assume im a novice/newbie. i do thatnk you for your input and explanation, you might be right some ppl are better at doing certain things than others ill look things over and make a decision if i think i can do it or not, dvd you did bring some good things to light for me to look at that i may not have looked at. any way i want to thank both you dvd and skinerd for your input.
what level do u think someone should be to take out a chip? 1 being worst 10 being best?

Please don't feel offended. I'm sure it wasn't meant that way. We all be buds here. It's all good.

I have removed bga chips several times. Fried one and I mean fried! I caked the plastic right off the substrate LOL! I'm a fair solder slinger myself and these tiny chips and traces are beginning to tax my old eyes!

In fact, I just bought my most recent 811 already modded. I got frustrated and the price was right, so I sprung for it.

Do you know there is a new card slot activation process, right?

[eevo66]

oh yeah lefty i saw that the other day wich is what made me think it would be easier and probably better to go that route

When it comes to these physical mods, and most other stuff too, but especially the physical mods, your not going to meet anyone better than skinerd. His word is gospel when it comes to mods. He doesn't have any problem working with BGA chips either.

Open one up and look, decide for your self if it looks like you can handle the task.

See how close everything is, make a decision your own self. If you have any experience at all, it should not be hard to decide.

Maybe even get an old 311 board, it has chips you can practice on. The flash chip is almost identical to the card chip, most other devices are surface mount too, practice and see how hot you need to get stuff to remove safely.

DVD recommends onboard glitching, that's what works for him.

I remove the chip, cause that's what works best for me.

Only you can decide what works best for your abilities.

you guys have been a lot of help. i want to thank everyone who posted to this thread. as skinerd said "i will open the moster up and take a look and decide if i think i can do it safeley or not". dvd you have made me much more aware of how tidious and hard this job could be. by no means am i an expert at testing but when it comes to slodering and moifying i feel pretty comfortable. one thing is for sure, i think i have learned a lot, not only about testing but what peoples meanings are when they post a reply to a thread. dvd's post was very helpful and im sorry it offended me and i thank you greatly for trying to help, ill post results after i open this animal up. maybe in the future ill have some good to offer as well. thanks again to everyone.
