[Galaxy S6 Q&A, Help & Troubleshooting] DagsyMc:
what a f**k about!!!!

Right then Jon,

sorry for my delay but not the greatest at reponding to things at the best of times, but with my own s6 in a right old state, and a 7y.o and 4 month old in the house, my pc time is limited.

anyways, im guessing you're a bit like me, and you've had your fair share of flashing roms and roots since the days of old! (Galaxy thru and thru for me s 1,3,4,6, plus tabs and watches).

this s6 gt-920f is a completely different kettle of fish mate. where you're at at the minute, if your still stuck in bootloop with no recovery, your gonna want to find twrp recovery, as you know mate, google will be your guide. you flash this just like a rom or the old cwm, download a zip, bang it in ap/pda in odin and let it flash. KEY NOTE IS MAKE SURE ODIN HAS ~"AUTO-REBOOT"~ UNTICKED, UNCHECKED, NO MARK IN THE BOX. THIS IS KEY TO THE RESTORATION PROCESS GOING FORWARD. Once odin shows that the file has flashed and passed, get ready to perform a three button power reset, Home button, Vol DOWN and Power for 8 seconds. when your pc makes the badong sound and the screen goes off, IMMEDIATELY SWITCH TO Vol UP, Home and Power, thus straight into recovery mode, AND WAIT.

You should see the blue and silver TWRP splash screen and then the recovery options. Firstly, wipe and format everything, dalvik, caches and perform a factory reset. twrp should ask you to type yes to confirm, do it, there's nothing there yet any ways. if you get any issues about cant mount data or some jazz, DONT PANIC, use twrp to reformat the partition to ext4, your pc should ping to show reconnection to the phone.

Now whilst still in twrp, nav to the reset options and reboot into download mode. if all has go well, the scren should have the regular greenish odin screen but without all the samsung odin mode in at the top. odin should show the phone as a connected device, you should be able to access your memory card from your pc to transfer rom zips etc and get the phone back up the way you are used to.

if on the other hand you want to get back to vanila stock style android, with the expense of a tonload of bloatware and crapps, you're gonna wanna take a goggle at stuff like "G920F Repair Firmware X.X UK YYY) , Where X.X is 5.1, 6.1, 7.1, depending on the original android version your brick was on, and YYY is your carrier or network operator, off the top of my head they are VOD, TMO, O2U, H3G.

AGAIN A KEY POINT IF YOUR GOING THIS ROUTE, THESE FILES ARE MADE FOR INDIVIDUAL MODELS OF S6 (THERES ABOUT 12 MODEL NUMBERS -YOURS IS AND ALWAYS WILL BE SM-G920F - SO DO NOT EVER STRAY FROM THAT NUMBER!!!! ) THAT MEANS YOU NEED TO BE FINDING FILES LIKE "G920XXU5EXUE 4 files repair firmwares", THESE ARE YOUR SAVIOUR. GET THE ONE THAT MATCHES YOUR PHONE AND CARRIER OR ONE THAT IS AS NEAR AS DAMMIT, AND AGAIN PLEASE MAKE SURE FOR THE LOVE OF YOUR PHONE THAT YOU ONLY GET FILES MARKED G920, ANYTHING ELSE WILL RESULT IN VERY SERIOUS ERRORS.

YOUR ALSO GOING TO NEED SOMETHING CALLED A PIT FILE, EASY TO FIND, LOOK FOR " S6 ZEROFLTE HIDDEN IMG FILE" IN GOOGLE.

USE OUR OLD BUDDY ODIN TO FLASH THE FOUR FILES YOU GOT FROM THE REPAIR FIRMWARE ZIP, WHICH ARE USUALLY LABEL AP, BL, CP AND CSC.. NOW TAP THE PIT TAB IN ODIN (IGNORE THE WARNING) AND NAVIGATE TO THE HIDDEN.IMG FILE YOU GOT AND BANG IT HERE. ON THE OPTIONS TAB YOU WANT TO TICK AUTO REBOOT, REPARTITION, and NAND ERASE ALL. i know, i know, you probably never use it out of some shear panic but right now its kosher.

start the flash and take a break. like a big break. the process is gonna wipe the phone in totalilty, rewrite every bit of code and software and reload like new after about forty minutes.

now, if it doesnt, there are a few things we can look at but am gonna leave it here and hope you can make some use of the ramblings of a lost man. my 6 is currently in an inverted touch bug where if i touch one side of the screen, the opposite side responds so its a proper nightmare, typing anything means that a becomes l, s becomes k etc. thisis down to me drunk flashing the wrong roms for and s6 edge, g925f, hence all my warnings earlier. anyways, i need a reefer and a scran after all this, God, allah, buddah i hope it helps someone.
