I have xbox360 slim . I am facing below problems. I am trying to RGH. I using nandpro(all versions) and other programs also. When I read the Nand : error: reading 250 block f9 When I write that nand: error: 202 programming block f9 when i erase the nand: error: 202 erasing block f9 Then I got E71 error. Please replay me as soon as possible how to overcome this problem ?
try starting with the system with the sync button pressed and see if it will clear out the fail, then start over.
You need to move 250 block f9 to the end of the nand using nandpro. Basically, exchanging one bad block for a good one. In the nandpro help file, there should be instructions on how to do this. If not, google the error and it should show you exactly how to move bad blocks on the nand. I've had this happen to me, but I had 3 different bad blocks. I followed a tutorial and moved the bad blocks, and all was good afterwards.
