- Rebased to AUI4 firmware

V1-b2

what's next? & Known Bugs we can't do much about or will sort eventually

- 420rom folder in internal storage needs deleting between every fresh rom flash - this wont matter until you need to select different rom choices - just delete this folder from internal using TWRP file manager

- you may get the odd systemUI FC in dex

-if A SYSTEM APP hasn't been removed, try uninstalling it you should now be able to - any updates installed over an original system app remain as they are data apps following an update

5 - REBOOT TO ACTIVATE ROM MODULE AND ENJOY!!

 

[exocetdj]

Please flash this module in magisk after setting up - this will prevent reboots if you accidentally hit camera app (this is an issue with unlocked bootloader fold 3s on AUHF firmware)

thanks to @ianmacd for this

 

[Who-Lep]

Awesome! Look forward to trying this out when I take plung to mod. Thanks!

 

[exocetdj]

please note that you will need to wait for the stock rooted firmware to upload and then follow my rooting guide first

 

[unix2208]

did you solve the problem with the camera in Rom?

 

[exocetdj]

did you solve the problem with the camera in Rom?

Sorry bud no - i havce heard there is a fix about (mishaal rahman's tweet) but til then we have to make do without

Im not expecting many rooters at the moment as a result of this camera issue admittedly but ported my rom over as i was bored

I will include the fix the moment it lands though (if its open source)

 

[exocetdj]

Turns out G-drive hates me everyone!!

I am re-uploading the patched AP file to Mega for my teammate to mirror - thanks for bearing with us!! (and apologies for my ADSL line eeeeek!)

 

[exocetdj]

Ok everyone!

The firmware has been uploaded - thanks to @abun880007

The Master Module Rom is uploading and will be live as soon as you have finished rooting - use this guide if needed

Goes without saying the camera is still borked on bootloader unlock, mind

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

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...

[exocetdj]

please see this post for a module to flash after flashing the rom - this will prevent the phone from rebooting when camera is pressed with an unlocked bootloader

Wait what is this tweet?! Can you link it or provide any details?

I spent about 7 hours yesterday rummaging through the open source kernel files for our device looking for things. Found the name of the camera, and camera driver files, but hadn't found disabling code pointing to it yet. Still have tons of code to sort through. Stopped when my head started hurting and decided to get drunk last night. Still trying to wake up lol

i must admit - its natural to doubt the validity of these claims when no proof of concept is provided and also when time ebbs on
- no reason to doubt Mishaal though - a very weird situation indeed

I just messaged Mishaal to see if information on it was willing to be shared with us

Hi mate! Yep very long time! Been on Sammy for a few years now ta for the kind words mate and hoping to support flip too. That's If the software is similar (which it will bw)

AFAIK twrp is in the making too

I cannot see any reason why we shouldn't support the flip soon.

 

[ltth]

Thanks for great work, just remaining to finish the camera fix, once more Big Thanks.
And as normal Knox is broked and warranty void when I root my F3!?
