Is there a way to go back to 4.4.2 from 4.4.3 on the T-mobile HTC One M8 ? There are some issues i'm having and there is no 4.4.3 RUU for the T-mobile M8 yet. Can anyone tell me how to do this ? I am rooted, unlocked bootloader, and have TWRP recovery. Please let me know.

Nope. When I try to flash it, it says security failed.

When I flash my phone back to 4.4.2 it says this C:\adb>fastboot flash zip update.zip
target reported max download size of 1830612992 bytes
sending 'zip' (1482813 KB)...
OKAY [ 54.302s]
writing 'zip'...
(bootloader) signature checking...
FAILED (remote: 12 signature verify fail)
finished. total time: 109.012s

and then thats it. I want to take it back to stock, but it wont let me.

You need to re-lock your bootloader before you run the RUU. And make sure to run the RUU as administrator.
