[HELP] HTC ONE M8 (AT&T) Will not Unlock. IMEI DATA FAIL! ERROR


Hello,

I am trying to unlock an HTC One M8 through SD Mode Editor.

Process seems to work then phone reboots back to bootloader and says "Get device IMEI success" then spams in RED text "IMEI Data Failed!" over and over down the screen.

IMEI Data Failed!
IMEI Data Failed!
IMEI Data Failed!
IMEI Data Failed!
IMEI Data Failed!

Then phone never gets unlocked

Any idea why this happens?

Thanks!

Please wait, preparing your phone...
Sorry, qcom is not yet supported.

This message appears when I press the button "do s-off"
what does it mean?

I have installed twrp-3.1.1-0-m8
Or should the recovery be different?
