Hi, already done that, same problem, the only thing that remains untouch is the unlocked bootloader
but I don't think that's a problem, correct me if I'm wrong. Thanks
Try to flash the newest stock firmware , maybe that will fix the issue.
And wait for the Pro's to help with the new "coming soon" rooting steps , files and guide.

what is really strange is that I managed to root the phone the first time,
then upgrading to BUL8 I started having this problem and now I can't go
back to BUL6 rooted stock rom because it gives me the same problem.
I hope @exocetdj and the other pros will come up with some sort of solution.

Is it safe to direct install v24 magisk? I tried earlier with a different magisk build and it put me into a bootloop, lucky my data was intact and I just refreshed in odin

Jah's making me crazy

yes

Also TO ALL USERS BVA9 rooted stock firmware has been uploaded and is now in testing

I have messed up bluetooth in the firmware but will provide a TWRP flashable zip to fix that (just flash after Magisk when updating to BVA9) - this is folder reset v1.1 and installs the stock bluetooth lib

This issue will only rear its head if you are trying to connect watch but that works perfect when the fix is flashed

I could upload a new firmware but with 20mb ADSL internet, im sure you guys will allow me to not have to do that and just flash a quick zip instead ;)

    F926B users - rooted firmware is now here

    This time round i have cooked in @Andrei1973 's WSM fix so no need for any modules to keep wearable pairings (cheers as always mate :) )

    Rebased to BUL8 firmware and including A7 TWRP from IanMacD

    Removed forrceencrypt and have also used df18bcf5 Magisk Alpha build (aka app-debug.zip) attached to this post for flashing in TWRP

    Update procedure

    1 reboot to download and load Odin

    2 Load the Odin files and uncheck "Auto reboot"

    3 Reboot straight to TWRP (remember the button combos!)

    4 ONLY IF YOU HAVENT GOT MAGISK ON INTERNAL STORAGE - check that MTP is disabled and copy app-debug.zip to adb folder then in CMD window "adb push app-debug.zip /sdcard"

    5 - Flash the app-debug.zip and then reboot to system from TWRP power menu

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

    To everyone else -> BUL8 firmware will hopefully follow this weekend if my kids and queries allow

    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)

    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

    Hi All!!

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

    Before you start, download "420rom_F926B_BUL8_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 :p

    Generally we're pretty selective with what threads are made into a sticky... And with the flat forum layout that came with the move to XenForo it's easy to filter the type of thread you want to find by clicking the prefix tags at the top of the forum (How To Guide in this threads case), so the need for stickies is even less.

    So no, unfortunately, I won't be making this thread into a sticky at this time. Great to see the progress being made here though. Let's hope someone gets a workaround for the camera disabling thing released soon.
    Fair comment there (y)

    was a passing query so no bother at all!

    Yes there has been very very brief glimmers of hope but sadly nothing yet. I'm sure this forum will explode with action as soon as a fix is found or what apparently has been found already is finally released :)

    ta muchly for your time (y)

    @Didgeridoohan hey man - i was wondering if there was anyway this thread could be made a sticky (if people find this thread useful??)

    We now have a tested root process and also a seamless rooted update process 😁
