[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Well, there is a saying which goes like this ;

"Don't try to fix which isn't broken"

You can make calls.. your phone works in all aspects.

Except that you dislike some uae built-in apps :)

Just disable those apps..

But if you have decided you want to jump in the "pseudo effect of update feels good" ship .. then i can't stop you.. its ur phone :)

But trust me you WON'T WANT TO HAVE LATEST UPDATES because i did what you want to do and now suffer :)

Okay but if you want to flash latest rom for your current country follow these steps.

1. See which rom/firmware is currently installed in your phone .. i.e : build numbers , and copy paste them here and also note them down so you can remember..

2. Since you want to get in this ship :) you need to ENABLE OEM UNLOCK AND USB DEBUGGING IN DEVELOPER OPTIONS, just to stay safe ** i will tell you why later **

3. Download latest odin from here i.e 3.14.4 https://technastic.com/odin-download-samsung-latest-all-versions/

4. Download latest firmware for your current country from here :

https://www.sammobile.com/samsung/galaxy-s7-edge/firmware/SM-G935F/BTU/

(if it is uk then there are 2 csc for uk .. btu and xeu)

5. *Important* make a backup of everything in your phone, then turn it off and go in recovery mode (by holding vol up + home + power buttons while its off)

Factory data reset and wipe cache.. then turn off phone..

6. Then put your phone in download mode while its off (by holding vol down + home + power buttons)

7. Run odin as admin on your pc, extract the firmware file you downloaded earlier.. it will give 4 files .. BL , AP , CP , CSC..

Select correct files corresponding to the boxes in odin..

*In odin options don't select any option other then F.reset time*

*USE CSC (NOT HOME CSC) IN CSC BOX..

8. Connect your phone to pc while in download mode (odin should detect the port.. if not install samsung drivers or smart switch for pc)

9. Press on start button to begin flashing.. once odin says success unplug your phone .. it will still be in download mode .. so hold vol down + home + power button to force reboot (once phone screen goes black immediately change from holding vol down to vol up + home + power .. this will put you in recovery mode.. do a factory data wipe + clear cache, then reboot phone)

**WARNING : DON'T UNPLUG YOUR PHONE WHILE ODIN IS FLASHING OR BEFORE IT SAYS SUCCESS ! **

10. Configure your settings and restore your data .. you should have btu csc now :)

*IMPORTANT*

*FLASHING A SECOND HAND BOUGHT PHONE (WHICH COULD BE PATCHED/MODIFIED BY A HARDWARE BOX) THROUGH ODIN CAN MAKE IT A HARD BRICK BUT IF OEM UNLOCK IS ENABLED YOU CAN FIX IT EASILY BUT IF SOME CERTIFICATES/IMEI WAS PATCHED THEN YOU WILL LOSE NETWORK !!*

*FLASHING TO LATEST FIRMWARE WILL CAUSE BOOTLOADER VERSION UPDATE AND YOU WILL BE STUCK WITH THAT BOOTLOADER (SINCE YOU CANNOT DOWNGRADE/FLASH ANY OTHER ROM WITH LOWER BOOTLOADER NUMBER OR EVEN TROUBLESHOOT USING A COMBINATION ROM*

*LATEST FIRMWARES HAVE SERIOUS PERFORMANCE/BATTERY ISSUES FROM MY EXPERIENCE AND YOU CAN DOWNGRADE ONCE YOU UPDATE TO A HIGHER BOOTLOADER NUMBER ! TRY EVERYTHING ON YOUR OWN RISK ! *
