I have Motorola droid razr m xt907 with unlocked boot loader & installed CM10 10.1.3 xt907 with recovery TWRP 220.127.116.11.Then i flashed Stock Jelly Bean 4.1.2,9.8.1Q-94-1 by using RSD lite successfully.After that I flashed Stock Kitkat 4.4.2 by using RSD liteV 6.1.4 .I get the error" Downgrade Security version,update gpt_main version failed
preflash validation failed for GPT."
So I update using OTA to Kitkat 4.4.2 (183.46.10) ,after downloading the update when I installed it,my mobile boot in boot mode selection menu, displaying Flashing error.
Soi tried to boot my mobile,but it starts & then shut down automatically.Then i boot my mobile in boot mode selection mode menu & select Recovery option(at that time mobile was 55% charged).The it starts installing the update showing Android on screen.When the update get finished my mobile displays black screen.Now i am unable to enter in boot mode selection mode by pressing Power,Volume up & down key.Nothing displayed on mobile screen.No Battery Indicator LED,also its not charging again.
If i connect it on my laptop in other devices it shows QHUSB_DLOAD.I think battery is drained & mobile is bricked.Please help to get my mobile in life.Any suggestion / help really appreciated.
