[Verizon HTC One (M7)] dottat:
Custom RUU for sense 6 and Lollipop 5.0.2. This file is not encrypted and is for S-Off users only! I posted an RUU mode flashable TWRP file at the bottom of this post... but if you would like to use an app like flashify to flash your own custom recovery that will work too right out of the box as this RUU is ROOTED!

Extended power saving mode now present...

This will wipe you phone.

Install EXE method)

Download exe.. Double click exe on pc and allow it to extract and do its thing.

Install Zip method)

Download file into working fastboot directory. Boot phone to fastboot mode and connect to pc. Type in the following commands.

fastboot oem rebootRUU

fastboot erase cache

fastboot flash zip VZWm7_6.22.605.3RUU.zip

first time you run this it will be short... so run it a second time

Example in second post..

fastboot flash zip VZWm7_6.22.605.3RUU.zip

The command prompt output will show you details as it flashes each partition and will show you when it has completed. At this time the green bar on the phone will appear 99% of the way across the screen.. Completely normal!~ Issue the next command to kick it out of RUU mode or optionally flash the custom recovery TWRP if you intend to root/flash custom roms and THEN issue the below command to get out of RUU mode.

fastboot reboot

(note) if you just want to reboot back to bootloader you can issue the command fastboot reboot-bootloader This will allow you to boot directly to recovery and start flashing/rooting fun.

NOTE.... VZW does not allow bootloader unlocking and since you must have root to use [MENTION=3437245]scotty1223[/MENTION] 's command you will need to flash a custom recovery and root the the stock rom.
