How To Guide SM-F926B ONLY!! Android 12 update and ROOT GUIDE - BVA9 rooted firmware provided - if you missed the good news, camera works :)

[little-endian]

But lets be clear - TWRP is still fundamental for rooting

Could you please kindly elaborate on that?

From what I understand, the process of rooting a Fold 3 with Magisk is to get the corresponding app as an APK file, using it to patch the AP part of the stock firmware which comes in several parts (AP, BL, CP, CSC) and then flashing that very AP result with Odin.

Also, the rooting guide as a requisite for the Dr. Ketan ROM sounds like after having flashed the patched Magisk AP file, one still deals with the stock recovery:

[*](Root F926B)

Unlock bootloader
You needs to download stock firmware (You can get stock firmware with Frija) and extract AP*.tar.md5 file and patch with magisk. Flash patched file with AP tab of Odin
Reboot to recovery and select to format data (Factory reset option on stock recovery)

So I wonder at what point TWRP necessarily comes into play here. Is it contained as recovery as part of the Magisk patching approach?

Furthermore, is it still (June 2022) the case that encryption and that DEX function only works in conjunction of a /data partition formatted by a stock recovery instance or are there meanwhile versions of TWRP which can handle the encrypted part?

At least with an old Galaxy Note 8, I got Magisk running with TWRP and encryption (at least, a password check during bootup is possible, probably only Samsung knows how much that encryption is worth to begin with).

Thanks, but so much for elaboration.

Your suggestion also raises further questions as to what might be the advantage of using that approach which seems to be based on that "420rom" compared to Dr. Ketan's.

Also, it mentions OneUI 4.1 in conjunction with some Galaxy Watch to be used with root where it remains unclear whether that is something exclusive now or also covered by that other Dr. Ketan rom.

Ok . Just do the first step of that guide ( to be rooted ) , and then Jump to Dr.Ketan's Rom thread ( and follow the instructions )

Hi All!!

This thread will now contain pre rooted Odin files for F926B users to flash and update

Before you start, download "420rom_F926B_BVA9_Odin_EUY.zip" from HERE

THIS IS FOR F926B ONLY

The process requires knowledge of basic adb and YOU MUST HAVE ADB INSTALLED BEFORE TRYING THIS

This will no longer wipe data but it is advisable to backup first anyway - i wont be responsible for any data lost that could have been backed up

PROCESS to update from rooted a11 or a12

1 - Unzip the 4 odin files from the zip provided in the link above & connect phone to PC

2 - load ODIN on PC and disable AUTO Reboot - Next load BL.tar in BL, AP.tar in AP, Stock CP in CP and Stock HOMECSC in CSC

3 - Click start to flash the files - when completed, keeping phone connected to PC, press and hold power and volume down and as soon as the screen turns off, press and hold vol up and power UNTIL in TWRP

4 - Head to the TWRP mount menu disable MTP

5 - ONLY IF YOU DONT HAVE A MAGISK.ZIP ON INTERNAL STORAGE copy app-debug.zip to your adb folder and then open a command window and first confirm adb is working by typing adb devices you should see your device listed and "recovery" next to the device in command window - this means adb is working - type adb push app-debug.zip /sdcard this should send the app-debug.zip to internal storage (or sdcard if you prefer)

6 - go to the TWRP flash menu and you should see the app-debug.zip, flash it to root your A12 device - this needs to be done everytime TWRP is flashed in Odin it seems

7 - reboot to system from TWRP power menu

You will boot rooted, updated and with intact data if all the steps above are followed correctly

------------------------------------------------------------------------------------------------------------------

PROCESS IF COMING FROM STOCK A12

1 - Unzip the 4 odin files from the zip provided in the link above & connect phone to PC (please ensure dev settings are enabled and that you have unlocked bootloader and checked "Oem unlock" is faded out under dev settings)

2 - load ODIN on PC and disable AUTO Reboot - Next load BL.tar in BL, AP.tar in AP, Stock CP in CP and Stock HOMECSC in CSC

3 - Click start to flash the files - when completed, keeping phone connected to PC, press and hold power and volume down and as soon as the screen turns off, press and hold vol up and power UNTIL in TWRP

4 - Head to the TWRP wipe menu and format device (type yes and press enter) - then reboot TWRP

5 - when TWRP has rebooted, go to the mounts menu and disable MTP -> this will allow us to send app-debug.zip (magisk) to your sdcard

6 - copy app-debug.zip to your adb folder and then open a command window and first confirm adb is working by typing adb devices you should see your device listed and "recovery" next to the device in command window - this means adb is working

7 - type adb push app-debug.zip /sdcard this should send the app-debug.zip to internal storage (or sdcard if you prefer) - go to the TWRP flash menu and you should see this app-debug.zip, flash it to root your A12 device

8 - as stated previously, i have disabled encryption therefore we just need to boot STRAIGHT to SYSTEM from the TWRP POWER MENU

9 -When phone reboots, set up as normal and you should now see a magisk stub in the app drawer meaning you are rooted
