What an awesome resource for hacking/fixing/owning all things Motorola. I wish I'd explored this site before I needed help unbricking my Droid Razr HD...I've fallen victim to the apparently not uncommon boot loop/phone won't get past the dual processor Motorola logo screen. I still have had no luck reviving the thing.
I've tried flashing a new FXZ thru fastboot using RSD Flasher to create keepdata and universal files with RSD Lite, but when I flash it, it comes back "Failed flashing process. 1/17 (or 1/15 for the universal version) flash partition "gpt.bin" -> Phone returned FAIL."
Any suggestions?
