CECH-2512B + factory 3.50
Same here. I've been following the 2 threads (including that one) in this forum that discuss the issue:
as well as a few other sites. I have tried their suggestions, repeatedly, for 3 days now. I think it's safe to say that I have searched. The new units that did have success were the CECH-2504 models, not the CECH-2512.
Now, having said that, I think that this is a new issue that's just coming up with the CECH-2512B that come preinstalled with 3.50. They seem to only accept a 3.50 FW update and reject everything else below.
I am no expert, but I have researched and I have tried. Flame all you want, but I think it should be safe to point out that this might be worth treating as a new issue that's just popping up.
BTW, for information's sake:
1. I entered service mode using psfServiceMod (12-13-2010 version) on an HTC Desire.
2. Tried the usual Mod 3.14 PUP + self 1, brick (or partial, since it was reversible with 3.50 using the same process).
3. Reverted to 3.50.
4. Tried 3.15 debug (don't start flaming that it's nonsense to try a debug FW on a retail unit, because I was just following a seemingly tested method). Fail.
5. 3.15 retail. Fail.
6. 3.41 retail. Fail.
7. Reverted to 3.50 successfully, but right back where I started.
