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

[pvillasuso]

@pvillasuso can you boot to TWRP currently? And when you're in it can you mount /data on the mount page - this'll show if /data is encrypted for you or not.

Yes I can go into TWRP , let me check that about mounting /data
Be right back

Edit : Nope I cant mount data , the checkbox does nothing when tapped, its like "greyed out"

 

[J0gurt]

Can you run Dex?

Can you describe exactly what you mean by that you went back? Were you already on A12 rooted? And you redid which steps in the 1st post?

These describe rooting starting in A11. Can you be specific about what you did - seems you had a process like @pvillasuso and you both are good. I'm not...

I did experiment a bit with my Z-Fold in the last days, by "went back" i mean i flashed an A12 stock rom with Odin downloaded from sammobile, to get a fresh start.

Then i did the steps OP shared with us in hist first post since i read that it could also be done by starting with a A12 stock ROM.

it works fine but i still have the stock recovery not TWRP. Today since i would like to have TWRP tried to follow the steps provided by pvillasuso (started from the same stock rom i mentioned above) but this will end up in a boot loop.

i wanted to have TWRP working to try out OP´s 420 ROM from his other thread. since the steps from https://xdaforums.com/t/magisk-rom-...ch-12-2021-released-08-01-2022.4335197/page-4 post 63 leave me with a broken TWRP where touch inputs wont work.

hope that makes it a little clearer what worked for me and what didn't.


for the DEX question, I am currently flashing a stock ROM, and repeat the steps from the first post and check DEX. give me a couple minutes

EDIT: DEX is starting but System-UI keeps crashing.

I did the same when I was rooted by OP's guide and wanted twrp too.
but just went to download mode and flash twrp file via Odin , rebooted to system , and all fine , got a working twrp .

Hey @exocetdj first of all, thanks for the root guide and your work!

is there a way to use Magisk Hide? Unfortunately, I can't find the option in the app that you included, I uninstalled the Magisk app and loaded the apk from Github directly, here I see the option but it doesn't do anything, it deactivates itself as soon as the settings are exited.

I´d like to use it for safetynet fix reasons

Is there any known way to get it working or is this not possible at the moment ?

regards

enable zygisk in magisk settings and reboot

then install safteynet fix 2.2.1 and reboot

then install any safteynet checker app from the play store - can confirm passes here

wow thanks that did the trick so, there is no more need for Magisk hide in order to hide root for certain apps ?

Edit: i might have found it, the "Denial list" (hope the translation is correct haha) seems to do the same job as Magisk Hide. maybe it was just renamed ^^

 

[exocetdj]

afaik its in development and wontwork for all

 

[exocetdj]

ok no progress on Dex today from my end - seems to be a commonn issue and @abun880007 reported an error message stating that dex wouldn't work due to a modded system

on a side note i have disabled WSM which means watch pairings remain on reboot - this was a fix in my rom already but module dependant meaning that watch pairings would go even if the module was disabled- thanks to @starbucks2010 for the wsm fix as always

ill upload a new firmware tonight with this fix and it has been based on BTB (no difference to MSR firmware as is OXM)

I may have figured something out how to get TWRP working.

-start with a A12 stock rom from sammobile or similar (flash CSC_OXM not CSC_HOME_OXM to be completely "fresh")
-root with steps from the first post in this thread (did not started Magisk app yet)
-do initial phone setup
-flash ONLY AP_twrp_F926B_A12.tar with Odin from post nr. 90 (uncheck auto reboot)
-boot to TWRP with hardware buttons and format data
-reboot to recovery with twrp menu
-sideload and flash app_debug.zip
-reboot to system with twrp menu
-finish the Magisk app setup (initial setup when starting the app for the first time)

However TWRP will only start when the phone is connected via USB to my laptop, otherwise it will just vibrate once and boot to system with an error popup:

[PDP]
back-up : fail
setup-wizard [FINISH]

while in TWRP I´m able to mount the data partition to answer your question couple of hours ago

@pvillasuso are you able to start TWRP without your phone being connected to a PC ?

EDIT: as @pvillasuso mentioned, this is the expected behaviour for TWRP on A11+ have to use an app to boot to recovery or connect it to a PC

EDIT2: i redid the steps to make sure they were correctly, after formatting data you have to reflash app_debug.zip otherwise Magisk will prompt for a restart every single time you open the magisk app.

 

[pvillasuso]

@pvillasuso are you able to start TWRP without your phone being connected to a PC ?

Yes , I can do that via magisk , or an app I installed
But I can't with the phone off and using hardware buttons
From what I understand it has to be done this way ( connected ) since A11

Edit : I have a note 20 ultra , also rooted with Dr.Ketan A12 ROM , and I asume is the same: to get into Twrp using hardware , it has to be done connected to PC (since A11)

 

[pvillasuso]

I may have figured something out how to get TWRP partially working.

-started with a A12 stock rom from sammobile (flashed CSC_OXM not CSC_HOME_OXM to be completely "fresh")

You are right about this , I did CSC_HOME, so that's why at some point I had to factory reset from stock recovery

This is why you didnt get into bootloop this time .

Gonna change and edit the guide I posted earlier

I Think you solved it

-boot to TWRP with hardware buttons and formated data
-rebooted to recovery with twrp menu
-I did sideload and flashed app_debug.zip again but was probably not neccessary since it detected a already magisk patched boot.img
-reboot to system with twrp menu
-finished the Magisk app setup (initial setup when first started the app)

However TWRP will only start when the phone is connected via USB to my laptop, otherwise it will just vibrate once and boot to system with an error popup:

Thanks for this!

Can you run Dex now without crashing?

 

[frwerewolf]

I have a question:
I don't need TWRP. I am on A12 stock now. Is there a way to root the phone with magisk only, like i did when i was on A11 by letting Magisk patch the AP file and then Flash it ? I did it on A11 and it worked fine. But cameras were desactivated. So i went back to stock and closed the booloader.

 

[frwerewolf]

We now have TWRP working on A12

Big thanks to @ianmacd for this and for @abun880007 for helping him with testing

I will produce a much easier rooting process later and will provide the neccesary files

I hope Soon...the first process is very much complicated And maybe you'll produce one with Magisk only and without TWRP ?

 

[J0gurt]

Yes , I can do that via magisk , or an app I installed
But I can't with the phone off and using hardware buttons
From what I understand it has to be done this way ( connected ) since A11

Edit : I have a note 20 ultra , also rooted with Dr.Ketan A12 ROM , and I asume is the same: to get into Twrp using hardware , it has to be done connected to PC (since A11)

Ah okay, didnt knew that its that way since A11. My last rooted device with custom recovery is still on Android 10 thanks for the information.

 

[J0gurt]

Thanks for this!

Can you run Dex now without crashing?

no, unfortunately not. Dex will start but System-UI keeps crashing. I can open apps though, but the UI eg. taskbar isnt availyble. As OP mentioned this is presumably an Error due to the modded system.

OP?

my name must be Ozwald Pinkerton!!

Hello everyone,

First of all I apologize for having to use a translator, but my English is pretty bad...
So here I am, I tried to root my fold 3 following the guide. But on second thought, I probably made a big mistake by misunderstanding the flashing process. I used the CP and CSC files contained in the last file downloaded with the Freja tool!
It did not cause any problem during the first flashing (I managed to access TWRP), but when I reflash the recovery at step 8 of the guide, then restarted. Android launched without bootloop and was working properly. But when I ran Magisk to finalize the root of the phone, it didn't work on reboot presumably. Then I finally tried again to perform the root installation by clicking on install somewhere in Magisk (sorry for my lack of precision on this point). This resulted in a system reboot, and the phone has not booted since.
Unfortunately, I tried everything and I can't access the download mode of the phone in any way!
I can only access the basic system recovery...
I hope someone can help me without having to change the motherboard of the phone by Samsung... ?

1. Try to do a factory reset from stock recovery , and try to boot to system

2. You can boot to download mode from recovery ( look for "reboot to bootloader" option , and connect phone to PC before that )

If you want to go back to stock , fresh install :

Get into download mode
Open Odin, and set the stock A12 files but USE CSC , not HOMECSC

Flash to stock !
And start again with the guide from there

PS.
Download mode (via hardware) =
Phone off
Both volume buttons keep them pressed + connect phone to PC

Good luck
