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

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)

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

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

here you go mate


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

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. 😊
