Write back your stock NAND. I bet you have RROD and your GPU needs a reflow.

first of all tks for you quick awnser.so the only thing to do its connect the JR2 to nand QSB,select stock nand and press write in Jr?is this corret

U will also need to cut power to the coolrunner or switch it to program if you wana boot the retail NAND

That's fine. You can also desolder CPU_RST to the same effect.

Sorry about the delay,but i write back my stock NAND. I have RROD and i reball my GPU and CPU.i the 2 times i reball the chips,i turn the console on and works,if iam play emulators the console works,if i gonna play normal games the console start the game and give errors on image,the image freezes whit grey stripes and the console its back to 3 RROD after i reboot.can anyone knows whats is possible to be this?

 

[Joo C]

Perhaps you can start by explaining HOW you reballed or reflowed the console. The lines you're seeing is indicative of a GPU problem

 

[Sick Maniacs]

i dont make myself the reballed.i know a guy and he reballd consoles and pc's.he never have any problems.so i dont know what to do more...

 

[Martin C]

Replace the GPU.

 

[Sick Maniacs]

ok.the hanna chip or rams dont make that kind of error?its a graphic error isnt?

 

[Sick Maniacs]

and sorry about the question,but can you tell me here i can order the GPU for Falcon near Portugal?
