[RAZR HD Q&A, Help & Troubleshooting] Seattle3D:
Hello,

I have 3 Droid Razr HD's that i've managed to hose up. I cannot get them into any usable state.

Issue:

* Phone powers on

* "M" logo with "Dual Core Technologies" shows

* Droid red eye animation loads

* "Welcome" "Choose your language" loads

* Pressing "start" ends with "Please wait, this will take a few minutes" and this just spins forever.

Facts:

* Official Motorola Data Cable

* USB 2.0 port

* I'm on Ubuntu 16.04

* I have Windows 8.1 PRO VM if needed though...

* I cannot get the phones to be recognized by RSD Lite 6.2.4 in this VM

* When I try to flash the stock firmware (VZW_XT926_4.4.2-KDA20.62-15.1_CFC_1FF.xml.zip) using Root Junky's rsd-flash.sh linux script, it fails after writing `recovery` with the following errors:

OKAY [ 2.292s]

writing 'system'...

(bootloader) Preflash validation failed

FAILED (remote failure)

* I've tried every damn thing I can find online.

* I've even tried booting recover then adb sideload and loading the firmware .zip that way. No GO.

Fu*&ing up 3 phones doesn't feel nice. Especially because i'm tech savvy and solid... bummed out.

Anyone want to help?

Thanks
