S8 frp on/illegal software/soft brick -->> fully restored & functioning/frp off

Good evening everyone!

For those of you who have a S8 like myself, I have decided to create this tutorial w/ pictures & files, as to how I was recently able to unbrick/undo the illegal software + frp on bootloop my poor S8 was forced to endure due to it malfunctioning after having it rooted & customized for almost 6 months. (Combination of my root + netHunter + Samsung Forced Itself Software Update while I was sleeping....next morning Blue Screen of Illegal Software Doom)

Things you will need:

MULTI FILES FOR RESTORE: https://www.androidfilehost.com/?w=files&flid=247148

SM-G950USQU1AQEF FULL: https://mega.nz/#!vs83yIKI!x1jPP4T12CGjlNDQXJJdypksVYeYb_cQnaNJm1ARTAg

-Ability to get into recovery + download mode

-Remove the sim card + external sd card

-Battery percentage at this point is irrelevant, though I HIGHLY ENCOURAGE you all to plug your S8 into your computer while in recovery mode for at least an hour or two in the event that is able to maintain a charge!

LINK: This is to my OneDrive S8 Restore Folder. What I used to restore my own is within this folder. If it says empty on some of the inner files my apologies as my internet isnt quite the fastest at work. But once its all uploaded (about 44% now) everything you will need and what I used is in it; NOTE: if your restore binary firmware number does not match my own AQEF with a 1 for the BL, then you must google the one it says on yours as mine will not work for yours! :)

-SAMSUNG DRIVERS

-ADB & FASTBOOT DRIVERS

-Odin 3.12.7(or higher)

---NOTE: DO NOT USE ANY LOWER OR PATCHED VERSION; you are trying to get back to stock NOTHING ELSE, MORE, OR LESS! Worry about rooting, unlocking later!

-The SPECIFIC firmware it states in recovery mode in bright yellow on top of the recovery menu. From there you need to search for that firmware's FACTORY combination file WHICH WILL HAVE THE LAST 2 NUM/ALPHA WITH A DIFFERENT ENDING THAN THE RMC'S & YMC!!!!

For Mine this is what I used:

COMBINATION_FA70_G950USQU1AQF3 (FB) --> THEN AQEF (VZW) --> FINALLY AQF7 (ATT)

[/U] FOR FB: Not the individual pieces, it must be the combo as your phone will load into Factory Binary OS first in order to recover your device!

---THIS IS VITAL as many including myself continued to get system fail! (0/1) from any version of Odin when trying to load what we believed was the correct firmware from our models + carriers.

---NOTE: This is important!!!! I was baffled that my phone's firmware (while on bootloop) stated it was Verizon's FA70_GUSQU1AQEF (bootloader 1, API 3) when my phone has always been AT&T even after rooting with SamPWND Snapdragon Variant (which btw THANK YOU! [MENTION=425678]SamPWND[/MENTION], you truly are a wonderful developer! My root was perfect! CPU tended to get hot more often then not, other than that, perfect!)

Whatever carrier you have is the last piece and PLEASE I ADVISE YOU ALL FOLLOW THESE STEPS EXACTLY AS I HAVE WRITTEN THEM ONE STEP AT A TIME!!!!!!!

Also, I am not responsible in any and all events, incedients, etc that happen to anyone's or anything's devices, etc. You are choosing to do this at your own risk!

-The

Recovery Mode Carrier's Firmware (RMC)

: Yes these are two separate pieces of firmware as you will go from Binary to RMC's and then finally your ACTUAL carrier's stock firmware.

-and finally,

Your Carrier's Firmware (YC):

If your S8 originally came with 7.0 Nougat you must stick with that Stock Firmware until the device is restored! Not 7.1 or .2, it must be 7.0! And do not use security patches as fillers!

FULL FIRMWARE ONLY! With all 5 pieces: BL, CP, CSC, AP (PDA), & USERDATA/UMS!

---NOTE: If your device reads *USQU1AQEF then your firmware (ALL OF THEM) must have a 1!!! If it reads *USQ2....your firmware must have a 2!!! This is due to your bootloader version! You cannot put a 2 in a 1 and vice versa!

Finally, the last 4 letters/numbers on your RMC must match both firmwares!! Do not use AQF7, ETC! If it says AQEF you must use AQEF only until you are able to get to the final steps with Your Carrier's Firmware.

PROCEDURE:

1) DOWNLOAD & INSTALL ODIN, ADB, & ALL DRIVERS AS STATED ABOVE

2) DOWNLOAD COMBINATION FIRMWARE, RMC FIRMWARE, & YOUR CARRIER'S STOCK FIRMWARE

3) PLACE ALL OF THESE IN A SINGLE FILE OR SOMEWHERE YOU CAN FIND THEM EASILY.

4) PLACE PHONE IN RECOVERY MODE (VOL UP + BIXBY + POWER)

5) SELECT FACTORY RESET -> YES

--NOTE: EVERYTIME ODIN FAILS YOU MUST REDO FACTORY RESET! EVERYTIME!

6) ONCE RESET IS COMPLETE SELECT POWER OFF, PUT INTO DOWNLOAD MODE (VOL DOWN + BIXBY + POWER), PLUG INTO COMPUTER

7) IN THE FOLDER WITH ODIN RIGHT CLICK THE .INI FILE AND SLECT EDIT

8) SCROLL DOWN TO UMS = 0 AND USERDATA = 0 --> CHANGE BOTH 0'S TO 1'S AND SAVE IT!

9) SELECT RUN AS ADMIN WITH ODIN & SELECT THE AP SLOT TO LOAD THE COMBINATION FIRMWARE FILE

----- THIS WILL TAKE TIME TO LOAD, BE PATIENT

10) ON OPTIONS IN ODIN HAVE AUTO REBOOT AND F. RESET TIME SELECTED ONLY

11) IN ODIN IT SHOULD SAY ADDED! FOR YOUR DEVICE, IF IT DOES NOT UNPLUG AND REPLUG YOUR PHONE IN

12) CLICK START

13) DO NOT TOUCH IT UNTIL IT IS COMPLETE, ONCE COMPLETE DO NOT UNPLUG IT AT THIS POINT UNLESS NEEDED

14) CONGRATS YOU SHOULD NOT BE IN FACTORY BINARY WITH ODIN READING PASS! CLICK RESET ON ODIN AND LEAVE OPEN

PART II

1) ONCE LOADED AND OPEN GO TO SETTINGS -> DEVELOPER OPTIONS -> OEM UNLOCK ->ENABLE & USB DEBUGGING -> ENABLE

2) GO TO WHERE YOUR ADB & FASTBOOT'S ARE & RIGHT CLICK + SHIFT -> OPEN CMD/POWER SHELL HERE

3) COMMANDS:

su

adb kill-server

adb devices

adb reboot-bootloader

4)YOU SHOULD NOW BE BACK IN DOWNLOAD MODE

5) IN ODIN LOAD IN THE RMC'S FIRMWARE IN THE AP/PDA SLOT ONLY (IF ITS IN PIECES ONLY SELECT AND USE THE AP FILE NOTHING ELSE! & NOT THE COMBO BINARY FIRMWARE YOU JUST USED)

6) IF ODIN SAYS ADDED! CLICK START ONCE THE AP FILE HAS LOADED

7) LET IT RUN, AND AGAIN ODIN SHOULD SAY PASS! CLICK RESET AGAIN ON ODIN AND LET YOUR PHONE LOAD

8)IMPORTANT! YOUR PHONE WILL MOST LIKELY BE STUCK ON THE SAMSUNG/CUSTOM/ETC SCREEN THIS IS FINE!!!

9) LET IT STAY LIKE THAT PLUGGED IN STILL WITH ADB AND ODIN STILL OPEN FOR 10 TO 15 MINUTES

10) NOW FORCE POWER YOUR PHONE OFF (FOR ME I USED VOL DOWN + POWER TO GET INTO UPLOAD MODE, THEN VOL UP + BIXBY + POWER, THEN POWER OFF, AND THEN VOL DOWN + BIXBY + POWER) AND BACK INTO DOWNLOAD MODE

PART III

11)ALMOST THERE!

12) DO NOT DO ANYTHING ELSE IN ANY OTHER ORDER THEN FOLLOWS I AM SPEAKING FROM EXPERIENCE AND HEADACHE!

13) NOW IN ODIN PLACE YOUR CARRIER'S FIRMWARE'S AP FILE ONLY IN ITS SLOT AND ONCE LOADED SELECT START

14) ONCE ODIN SAYS PASS! LET YOUR PHONE LOAD FOR 5 MINUTES, IT WILL LIKELY BE STILL STUCK ON THE LOADING SCREEN THIS IS FINE

15) CLICK RESET ON ODIN, PUT YOUR PHONE BACK INTO DOWNLOAD MODE, AND PUT THE BL FILE IN ITS SLOT AND ONLY THE BL FILE

16)FINALLY, AFTER ODIN SAYS PASS! & ONCE YOUR PHONE HAS LOADED UP WAIT 5 MINUTES! CLICK RESET ON ODIN, PUT THE PHONE BACK INTO DOWNLOAD MODE, AND LOAD THE CP, CSC (OR HOME_CSC), AND USERDATA FILES IN THEIR SLOTS (YES ALL 3 AT THE SAME TIME), THEN CLICK START ON ODIN

CONGRATULATIONS YOU HAVE A S8 AGAIN!!!

ONCE YOUR DEVICE HAS LOADED, GOOGLE ACCOUNT ADDED, SETUP COMPLETE, AND YOUR SAMSUNG ACCOUNT HAS BEEN ADDED, DEVELOPER OPTIONS ENABLED, BATTERY 100%, GO AHEAD AND INSERT YOUR SD + SIM CARDS, RESTART, AND THEN FINALLY GO TO SETTINGS -> SOFTWARE UPDATE ->UPDATE SOFTWARE

NOW, you can get back to all your shinanigans with rooting, etc!!! :)

I hope this helps and if you have any questions don't hesistate to ask!

xoxoxo,
