S6 failing to boot - stuck on factory reset

Hey, my phone has been playing up and generally malfunctioning lately. It seems to work fine for a day or so before freezing, and either rebooting itself or forcing me to manually reboot it using power + volume down. This seems to send it into a bootloop where it generally freezes during the Samsung animation with the pulsing squares. This sequence continues with me manually rebooting, also trying to boot to safe mode and to recovery and after various attempts, i successfully got into recovery without it freezing on the blue android.

I then decided to factory reset as a last option, having looked around on forums for solutions. However, I now do not know what to do as it seems to have frozen during the factory reset. I dont have screenshots but the script reads as follows :

dm-verity verification failed. . .

-- Wiping data. . .
Formatting /data. . .
Formatting /cache. . .


It has been on that for the past 30 minutes and so i have assumed it has frozen. I'm afraid to force another reboot in case it is accessing memory, any suggestions on what to do?

It is up to date on fully stock software, has never been rooted and i have never attempted to do so. Also only around a month old.
Any help would be appreciated, thanks

Bricked D801 - TOT & KDZ recoveries both failing?

I've got a T-Mobile D801 and tried flashing to the stock lollipop rom D80130b_00 using TWRP and the instructions on this page, but the flash must have failed. I did a full factory reset back to stock 4.4.3 prior to attempting this flash and I'm not sure what (if anything) I did wrong for the flash to fail. I can boot in factory reset mode and select clear everything, but then I just see the android guy with gears turning for 2 seconds and the phone reboots again.

Now I'm in a bootloop where I get an "error: Boot certification verify" above the T-Mobile startup logo followed by a "Demigod Crash Handler: Critical Error!" screen that provides options for rebooting (volume down) or putting the phone into download mode (volume up). After using the volume up the screen displays "Volume Up is pressed: Jump to Dload mode" and after connecting via USB appears in device manager as "LGE AndroidNet USB Serial Port (COM41)". I can't (1) boot directly into download mode or (2) get back into TWRP.

I've tried both the KDZ and TOT methods listed in this thread and neither are working. The LG Flash Tool 2014 / KDZ option starts the LG Mobile Support Tool, but it fails every time once "S/W Upgrade is in progress" reaches 4% with a generic "Upgrade stopped due to an error" message.

The TOT method fails every time with a "Model Information Check FAIL!" message. The full text is - "PID: NULL, IMEI: NULL, Model: , DLL:801, BIN: BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot , SWV: , SWOV: , Model Information Check FAIL! , 00000000"

I've also tried using srktool to repair fastboot, but it gets stuck at "waiting for device".

What do I try next? :eek:
