i really screwed up my d850 att g3. found this on a forum. and it fixed my bootloop. flash tool didnt work for me.
Found this on AndroidCentral: Saved my life – it got my phone back to original. Hope this helps others.
*****************************************************************************************************************
What worked for me was from the TWRP terminal command was to type
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit enter
type
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
then hit enter and reboot.
it booted up to last rom i put on phone.
