Title: How To Solve E80/e81?
Post by: BDHTagger on December 13, 2009, 06:34:00 AM
Hello guys, I'm having a problem here.

What happened:
I received an 3 RROD repaired Xbox 360 with E80 error. When I pulled out the mainboard, I noticed U6T1 to come off the board. It came off. That would be the cause of the E80. The person was telling me that her kids wanted to play Guitar Hero, and needed to update, which failed. I guess not everyone is carefull while repairing RROD's.

What do I have?
Two important things: the CPU-key and two identical NAND dumps.

What did I try?
Changing LDV values to different values. I managed to show the boot screen, and let the Xbox 360 ask for an update CD. The previous installed version was 2.0.6717 and the update is 2.0.7371. When I insert a USB-drive or an CD with dashboard 7371 it shows E81, when I try a different kernel, it isn't even trying to update.

Trying to solder U6T1 from my spare board was to difficult, it failed.

Does anyone know how to solve the problem??? I'm in a nice situation, because i have the CPU-key and NAND dump, but for some reson (knowledge I guess) I can't get it to work?

Thank you for helping me (IMG:style_emoticons/default/wink.gif).

i am not even going to get into the LDV value...that's for the fuseline.......why would you mess with it as a first resort when you clearly seen that U6T1 was removed...... (IMG:style_emoticons/default/blink.gif) the only way you mess with that is when you need to match the fuseline(Efuse blown) with the dash......

anyway you know you do need that U6T1 back on the board right? failed or not...you being silly?
and also is the R6T3 removed that will cause this to...

P.S don't you think this belongs in the Xbox 360 Hacking Forums

Adding U6T1 is not gonna be an option for me (tried but failed).

Is a downgrade possible? I tried building an 1888 image, but now I receive a 0022 error.

Any help???
