Great write up, came in helpful as I had to replace my LCD and digitizer, BUT, after I had replaced them, my phone went into bootloader mode, I flash the SBF .602 and it went great, you know 10-12 minute write time. I followed all the steps to a T. Pulled the battery, power button + home button, goto recovery wipe data/factory reset, wipe cache then reboot. when it boots back up I get the red Motorola symbol for 10-15 seconds then goes to the green android guy with the yellow ! mark, double volume buttons and goes back to recovery. Any idea to why this happens???? I SBF'ed 3x's with different disks just to make sure it wasn't a bad disk. Gave up on it and said to heck with it and put the old parts back together and everything worked fine.
Just a heads up with what I have: DroidX, Rooted, sys 4.5.602, Android ver 2.3.3, pretty much stock except for root. I did buy this phone used off EBay, everything works except Vibe and the LED notification light. The LCD and digitizer are from another phone that didnt have a motherboard so I just swapped out mine.
Thanks a bunch if you or anyone has an idea to why I am having this issue from swapping out the motherboard.
