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

Thanks for the response. I've been going through the post you recommended.

The phones I have are:

post-June 2014 (July 29th 2014 to be exact)

.182.46.15

The post recommends I flash 183.46.15 to them, but I have not found a way to do this. I'm on Ubuntu Linux and cannot find a tool to perform the flash. I tried Root Junky's rsd-flash.sh script with the VZW_XT926_4.4.2-KDA20.62-15.1_CFC_1FF.xml firmware. Even tried editing the .xml to remove the lines recommended in the post you provided:

<step operation="getvar" var="max-download-size" />

<step operation="flash" partition="partition" filename="gpt.bin" MD5="....MD5 sum here...." />

<step operation="flash" partition="tz" filename="tz.mbn" MD5="...MD5 sum here...." />

This did not work either. Same errors just after writing 'recovery':
