First of all, let me give you a big tahnk you for all the work you do to help us with the problems we have, about 3 weeks I bought a Atrix 4G AT&T, it came with GB 2.3.6. build(I think taht is) 4.5.141.. by accident, I OTA to 4.5.145, and the problem is that my battery has gone crazy, it passes from full charge to 0% in about 4 hours and stay like that for about 5 hrs, I succesfully rooted it following the cmd (entering via fastboot and typing the commands) method, to try the battery calibration apps found in the G Play, but none did worked, finallyI did a factory reset( some user from another spanish forum told that could work) but nothing, it keeps all messed up, then I found tht unlocking the boot I wolud be able to flash CWM that has an option to clear the battery info and return it to normal function, but the point is, that someone in the previous forum told me that this bukid (4.5.145) can´t be unlocked, beause is the newer one and nobody has tested it (and would hard brick the phone), could be someone be kind enough to tell me if this process is safe to use in my phone, and if somebody has already used it and how it went...
