[Samsung Galaxy A53 5G] OrthodoxOxygen:
THIS GUIDE HAS BEEN TESTED AND HENCE PROVEN TO BE INEFFECTIVE ON 05/12/2023. I AM LEAVING IT UP, HOWEVER, IN CASE SOMEONE USES IT TO DEVELOP A METHOD THAT WILL WORK.

IF YOU KNOW A METHOD OF UNLOCKING THE A536W (CANADIAN MODEL) OR KNOW HOW TO FORCIBLY FLASH DIFFERENT MODEL FIRMWARE ONTO A536W,

PLEASE CONTACT ME!

I AM NOT RESPONSIBLE FOR ANY BRICKED DEVICES, LOST IMEIs, OR WHATEVER ELSE THAT COULD COME FROM ATTEMPTING TO FOLLOW THIS GUIDE. YOU SHOULD KNOW THE RISKS BEFORE FOLLOWING ANY GUIDE - ESPECIALLY WHEN IT COMES TO SOMETHING AS SENSITIVE AS FLASHING FIRMWARE AND UNLOCKING A BOOTLOADER.​

GUIDE:

1. Download the attached files (Odin PatcheD 13.3.4 and Samsung Drivers).

2. Download the following firmware files: A536B & A536W (FOR THE A536W FIRMWARE, SELECT WHICHEVER CSC MATCHES YOURS. TO CHECK YOUR CSC, GO TO THE STOCK SAMSUNG DIALER AND PUNCH-IN "*#1234#". If it says "OYV", I'm pretty sure it means it's carrier-unlocked. Just use Google to see what CSC your carrier uses. Mine, for example, would be "PMB" because I use Public Mobile.

MAKE SURE WHATEVER TWO FIRMWARE FILES YOU CHOOSE BOTH HAVE THE SAME BINARY NUMBER.

You can flash-up binary numbers and side-flash, but you can't go down, so if your CSC hasn't released a firmware file with binary "5" and you manage to flash a binary 5 file, for example, you won't be able to revert until a binary 5 firmware is released for your CSC.)

3, WHEN ALL FILES ARE DOWNLOADED, USE RAR OR 7ZIP TO EXTRACT THEM. MAKE SURE ALL ARCHIVES ARE EXTRACTED TO THEIR OWN SEPARATE FOLDER FROM THE REST. Make sure Odin gets its own folder, the A536B firmware gets its own folder, and the A536W firmware gets its own folder. The Samsung Driver is a quick, one-time installation, so, it doesn't matter where it goes, really, because you can delete the executable-file right after the next step.

4. INSTALL THE SAMSUNG DRIVERS. Should be pretty self-explanatory. DON'T DO THIS IF YOU ALREADY HAVE THEM INSTALLED: it's a waste of time.

5. REBOOT YOUR PC. You can skip this step if you already had the drivers installed, though.

6. MAKE A BACK-UP OF ANY FILES YOU WANT TO KEEP. AFTERWARDS, POWER-OFF YOUR PHONE, WAIT 60 SECONDS TO ENSURE FULL SHUT-DOWN, AND REMOVE THE SIM-CARD AND/OR SD-CARD JUST TO BE SAFE. ONCE REMOVED, POWER YOUR PHONE UP AGAIN.

YOUR DATA WILL BE COMPLETELY ERASED BY THE END OF THIS, SO, THIS STEP IS IMPORTANT.

7. SIGN OUT OF YOUR GOOGLE ACCOUNT, AND SIGN OUT OF YOUR SAMSUNG ACCOUNT. DO THIS FROM WITHIN THE PHONE'S SETTINGS. REMOVE ANY AND ALL FORMS OF SECURITY: FACE-RECOGNITION, FINGERPRINTS, PIN, PASSWORD, OR WHATEVER ELSE YOU USE. IF YOU DON'T REMOVE THESE, IT MIGHT BLOCK YOU OUT OF YOUR PHONE WHEN YOU RESET.

8. TURN YOUR PHONE OFF. WAIT 60 SECONDS TO ENSURE FULL SHUT-DOWN. AFTERWARDS, INSERT YOUR CHARGING CABLE, WAIT FOR THE VIBRATION AND CHARGING-INDICATOR, AND THEN HOLD THE POWER BUTTON AND VOLUME-UP BUTTON TOGETHER UNTIL THE STOCK RECOVERY SHOWS UP. CLEAR YOUR CACHE, AND THEN DO A FACTORY RESET. THEN SELECT POWER OFF, AND WAIT 60 SECONDS.

9. POWER THE PHONE ON AND WAIT FOR IT TO SET-UP. DO NOT SET ANYTHING ELSE UP BESIDES WI-FI SO THAT IT CAN DO ITS THING. DO NOT PUT A FORM OF SECURITY, SUCH AS A PASSWORD OR PIN. DO NOT INSERT YOUR SD-CARD AND/OR SIM-CARD.

IF THE PHONE HASN'T ASKED YOU TO SIGN INTO ANYTHING (LIKE GOOGLE) IN ORDER TO PROVE THAT YOU OWN THE PHONE, THAT MEANS YOU CAN CONTINUE WITH THE REST OF THE GUIDE.

10. WHEN IT'S DONE DOWNLOADING WHATEVER AND DOING INITIAL SETUP, GO TO SETTINGS, "ABOUT PHONE", "SOFTWARE INFORMATION", AND TAP "Build Number" UNTIL "DEVELOPER MODE" HAS BEEN TURNED ON.

11. GO BACK TO THE SETTINGS' MAIN-MENU, AND SELECT "DEVELOPER OPTIONS".

12. SCROLL DOWN TO "USB DEBUGGING". TURN ON "USB DEBUGGING", "3GPP AT COMMANDS", AND "DISABLE ADB AUTHORIZATION TIMEOUT".

13. SCROLL DOWN A BIT FURTHER TO "DEFAULT USB CONFIGURATION". MAKE SURE IT IS SET TO "TRANSFERRING FILES".

14. CONNECT THE PHONE TO YOUR PC VIA USB CABLE (MAKE SURE THE CABLE IS MTP-COMPATIBLE), AND ALLOW YOUR PC TO LINK WITH YOUR PHONE (MAKE SURE YOUR PHONE'S SCREEN IS ON WHILE DOING THIS AND THAT IT DOES NOT TURN OFF).

15. UNPLUG PHONE, WAIT A COUPLE SECONDS, AND PLUG IT BACK IN JUST TO MAKE SURE IT'S PROPERLY HOOKED-UP. ACCEPT ALL PERMISSIONS.

16. REBOOT PHONE AND PC.

17. START ODIN.

18. USING THE

A536B

FIRMWARE, MATCH THE CORRESPONDING FILES AND FIELDS (BL FILE IN BL, AP FILE IN AP, CP FILE IN CP, AND

CSC FILE

IN CSC [

NOT "HOME_CSC" FILE

]).

If you want to watch a video to help with this step, this one shows you exactly what to do.

19. TURN YOUR PHONE OFF, WAIT 60 SECONDS, AND THEN PLUG IT INTO A POWER SOURCE (NOT YOUR PC). IT WILL VIBRATE. AFTER IT DOES, HOLD VOLUME UP AND THE POWER BUTTON TO ENTER RECOVERY. WHEN YOU'RE IN THE STOCK RECOVERY, SELECT "Reboot to Bootloader". YOU SHOULD NOW BE IN DOWNLOAD MODE. NOW, CONNECT YOUR PHONE TO YOUR PC VIA MTP-COMPATIBLE USB-CABLE.

20. IF ODIN DETECTS YOUR PHONE, IT SHOULD SAY "Added!".

21. IF ALL IS A WELL, SET YOUR PHONE DOWN IN A PLACE IT WON'T BE MOVED OR KNOCKED-OVER, MAKE SURE THE CABLE IS PROPERLY IN BOTH ENDS (PC AND PHONE), PRESS "START", AND DON'T TOUCH YOUR PHONE UNTIL IT'S DONE.

22. IF ALL GOES AS THEORIZED, YOUR PHONE SHOULD BOOT UP AFTER AWHILE, AND IT SHOULD BELIEVE THAT IT IS A A536B (because it technically is: the only difference between models are the bands they use for cellular-reception).

23. SET UP ONLY WI-FI, AND DON'T SET-UP ANY SECURITY. DO NOT SIGN INTO YOUR GOOGLE OR SAMSUNG ACCOUNT. GO TO SETTINGS, GO TO "ABOUT PHONE", GO TO "SOFTWARE INFORMATION", AND TAP "Build Number" UNTIL DEVELOPER OPTIONS ARE ENABLED.

24. SAME THINGS AS LAST TIME: TURN ON USB DEBUGGING, DISABLE ADB AUTHORIZATION TIMEOUT, ENABLE 3GPP AT COMMANDS, AND SET THE DEFAULT CONFIGURATION TO "TRANSFERRING FILES".

25. REBOOT YOUR PHONE.

26. GO BACK TO DEVELOPER OPTIONS, AND SCROLL UNTIL YOU SEE "OEM UNLOCK". IF ALL GOES AS PLANNED, YOU SHOULD BE ABLE TO TURN IT ON. AFTER TURNING IT ON, BOOT INTO DOWNLOAD MODE BY POWERING OFF, WAITING A MINUTE, HOLDING BOTH VOLUME BUTTONS (

DO NOT HOLD THE POWER BUTTON

) WHILE PLUGGING IT INTO YOUR PC VIA MTP-COMPATIBLE CABLE. IT SHOULD BOOT UP IN DOWNLOAD MODE.

27. WHEN IN DOWNLOAD MODE AND CONNECTED TO PC, HOLD THE VOLUME-UP BUTTON TO ACCESS THE BOOTLOADER-UNLOCK MENU, AND THEN HOLD VOLUME-UP AGAIN WHEN PROMPTED TO UNLOCK YOUR BOOTLOADER. PROCEED EVEN IF IT SAYS ALL YOUR DATA WILL BE ERASED: THAT'S TO BE EXPECTED. WAIT FOR YOUR DEVICE TO REBOOT AND WHATNOT.

28. SUCCESS! (

HOPEFULLY!

)

29. IF YOU DO GO BACK TO A536W FIRMWARE (I don't think phone-calls and whatnot will work on an incompatible CSC, so you might have to), I HAVEN'T LOOKED INTO IT MUCH, BUT I DO

NOT

RECOMMEND FLASHING THE "BL" FILE, AS

THAT'S THE BOOTLOADER FILE AND COULD POTENTIALLY CAUSE A HARDBRICK OR CORRUPTION

OR SOMETHING. BE CAUTIOUS. WHATEVER YOU CHOOSE TO DO IS YOUR RESPONSIBILITY.

MAKE SURE TO DO YOUR RESEARCH
