ANSWERED RGH trouble

[retrosling]

I successfully dumped my nand and wrote a new one with jtag tool, then when i went to boot into xell it didn't work

the coolrunner chip stays red and is set to phat and nor as it sould be.

i have got some pictures of my soldering

On this wire I had QSB's installed but removed them along with a couple of resistors. probably my problem i'm guessing?

i failed to desolder the pin header so left it in and soldered to the correct pin. I believe this is the power source if so i get a red light so...

I think this one is ok too?

Did you not read the stickys beforehand?

'Pics' and 'roadmap for noobies' are the two important ones for you.

 

[retrosling]

Thanks for the reply, If needs be i can try and get hold of a better camera. can you make out the missing resistors? im getting some 33ohm 1/4W resistors now but im not totally sure what im doing. would it boot up without the resistors at all?

 

[Martin C]

I can't see which are missing - they're labelled. Can you let us know?

 

[retrosling]

it says R4B24, and R4B25, the little black square closest to the hana chip

 

[Martin C]

You definitely need these replaced.

Judging by your work, I'd get someone else to do it.

 

[retrosling]

thanks, so can you confirm this could be the reason i am not booting xell? also how much are we talking here for repair?

 

[Martin C]

Yes, these are needed points so get these fixed first.

Cost - depends where you are and who you send to.

 

[retrosling]

well, i managed to get hold of some resistors. 33ohm, 1/4 w. i could give it a bash i suppose?

 

[Martin C]

Up to you. Support for this stops here though as you've decided not to take the advice and get someone else to solder it.

If you read my roadmap sticky, you should be able to boot with the stock NAND and CR set to PRG or NOR.

 

[retrosling]

On taking a closer look, its far too small for me to give it a go really. i'm in the south of england if you know of anyone?

 

[Martin C]

Don't rule out postal options. Myself and others get consoles all the time to repair from other people posting them.

 

[retrosling]

I'm no ruling it out, I'm sure it would be much easier for someone with expertise and the right tools to do. I don't mind postage if the price is right. Any suggestions?

Hi, I have a better picture of the damage now

Well that looks like your missing one or two a friend of mine had the same problem but he found an old mother board from something lying around an used the resistors from it an he had luck but yea if you don't fill comfortable doing your self have somebody else do as those little resistors are a pain an you have an connection bridge also R4B24 an R4B6

 

[Martin C]

As long as you don't do anything else to it, I can fix. PM me.
