I'm assuming you don't have a backup of its nonvol region 154 made before you did the previous flashings or you'd already have tried restoring it. So it seems you're at the point where you may as well erase 154. Make a copy of it first anyway before you do. Suggested commands:

The first command will stall the process before erasing if it's unable to dump region 154 successfully in the second one. If you already have a very recent copy of nonvol made after the cross-flashings then just run the last two commands. Good luck. Be sure to read again my comments in Posts 38 & 40 before attempting this. It may just die completely if it has a failing flash chip.
