Ok maybe all isn't lost just yet in that case and there's some feint hope still.

Some things i'm just not fully understanding however ... you said in your first post that you'd re-formatted the device using RMPrepUSB which means at some point the device managed to be seen in MSM at least for a while. However, the first txt cmd in Update.txt should have resulted in Update.log reporting that it failed! That's because gupdate.gcd should not have been present, so it shouldn't have reported as successfully deleted. Seems that the format wasn't in fact properly completed and there may well be other files still there and so the possibility of one being corrupt remains. Are you certain that RMPrepUSB properly reported it finished the format earlier?

It's good that 41 dumped it's full region size. On the other hand, failing to write regions 14 and 127 using xrgn isn't great. No entry after 'reboot' is expected seeing that didn't happen.

Would you please post a copy of your 41.bin for examination. It's encrypted so if you open it in a hex reader yourself it'll appear to be all 'empty' FF bytes but i can examine it for any obvious damage. You can attach it directly to your post using the function in the advanced editor (use "Go Advanced" button) provided you compress it to a ZIP or RAR file first, or you can just upload it to a free hosting site like MegaNZ if you prefer and send me the link by Private Message.

I'm ok with pressing on with this if you are, even if it's just for educational purposes because i still have a few things to try if you're up for it.
