RGH Problems with bad block

[muggen]

Hello.

First of all i'd like to say hi, as i just registred on the boards.

Im having a problem with my RGH Trinity. Bought it off someone around xmas. Been working great so far but ran into problems trying to flash new dash.

Im currently on 13604 version and was dumping my nand with nandflasher 360. When i do i keep getting bad block (bad LBA at block 0xf8 (raw offset 0x3ff000)
I tried to ignore this as it's working on my current machine. But when i run the nand through xebuild GUI and reflash it with new version it wont boot up.
I get E71 and RROD after the xbox swirl. I have now flashed back my dump and it runs fine again.

But the thing is id like to update my machine the the newer version. And im running out of ideas.
So i would be more than pleased if someone had an idea on what to do.

Thanks
