Description of problem:

I bought this corona v1 board in this state, when i try to turn on, its only beeping once, but doesn't turn on. Reportedly someone tried to install rgh in it, but he flashed a bad file to the nand. I tried to read and write with Nanad-x and with J-runner programmer, but no success, only get this message:
Version: 03
Flash Config:0x00000000
Can not Continue

After i didn't find any scratched component or damaged trace on the motherboard, i tried to look for a bad nand flash recovery solution, and read many thread how can i take my nand to bad flash mode, but i can't found any useful thing for slim corona motherboard, only for phat consoles.

Please help me if you can!

My readings (based on Martin's nand-x troubleshooter thread) :

1: 2.47v
2: 3,32v
3: 2,92v
4: 0v; 42,7 ohms
5: 0v
6. 0v (1,13 Kohm)

Was the console working before you started: No

are you sure its a corona v1 ?

also, have you tried BAD FLASH RECOVERY SLIM ?

 

[Eazywolf]

Yes i', m sure, its Corona V1 ( Have 16mb nand, post out, and r2c10 on its place). I already read this thread what i show me, but i can't found that components on my corona. That motherboard in thread is a trinity. And the xbox-scene forum links are all dead.

Welcome to the world of buying faulty consoles.

Good luck in getting it fixed. Personally I'd replace the southbridge as a start, since your SPI readings indicate it's faulty.

 

[Eazywolf]

Thank you for answering! So the bad nand file flashing is impossible to cause of this readings on spi? Because the 1,13 Kohm on 6 ? If i reballing the southbridge its enough, or i have to ordering a new one and completly replace it?

 

[Martin C]

Replace the southbridge.

I will order a new one, and replace it. I will post my results when it arrives and its on place. Thank you Martin!
