[App][Camera][Infinix Zero 8] [Need Help] Stock Camera App Port to Custom Rom - Android Q&A, Help & Troubleshooting

I am new to xda and this is my first thread so if this thread is not in the right place sorry for that.
Now i want to port the stock camera app from the stock firmware [my phone (Infinix Zero 8, Mediatek G90T MTK6785) running android 10-Q,] to custom rom/ GSI Pixel Blaster based on android 11.
Any advice/help is greatly appreciated.
1. The idea that i have is to extract the apk from the stock firmware,
2. Find the libraries associated with the apk using lib check app from google play
3. Zip them together and create a flashable zip.
The reason for porting is that my phone has a quad-camera setup 64MP main camera, 8MP Ulrawide, and 2 MP depth and 2MP depth now all the other camera apps from custom ROMs and google play only detects one camera 16MP. similarly for the front camera.

Original Guide by @kusti420
- make sure you have your stock rom by hand, and in case youre also using a new mediatek device make sure you also have mtk-bypass utility and sp flash tool by hand just in case or any other way of restoring your stock rom
you cant have magisk patched boot image installed unless you have also flashed a different product img
- under developer options enable oem unlocking
- adb reboot bootloader
- fastboot flashing unlock
- fastboot flashing unlock_critical
- fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
- fastboot --disable-verity --disable-verification flash vbmeta_system vbmeta_system.img
- fastboot reboot fastboot
- fastboot flash product product_gsi.img (Download product from here- https://forum.xda-developers.com/t/tutorial-magisk-on-gsi-on-devices-with-dynamic-partition.4311045/)
- fastboot flash system system.img (must be arm64 A/B)
- fastboot erase userdata
-gsi should boot now (firstboot takes time)
- do not format in TWRP (https://forum.xda-developers.com/t/unofficial-twrp-3-5-2-for-infinix-zero-8-x687.4303243/) erase userdata in fastbootd mode not in bootloader but fastbootd mode
______________________________________________________________
Some Problems
1. Old Fastboot drivers will cause incomplete flashing and you will not get error
To see if you have old drivers type adb reboot fastboot if device reboots to fastboot d then ok if device reboots to bootloader or simple reboot then old drivers​2. Incorrect GSI files
3. bootloops or stuck at bootmight be caused by not doing fastboot erase userdata

I do not have the links but these 2 gsis work on Infinx Zero 8, kindly search google for files, it's easy to find
- under developer options enable oem unlocking
- adb reboot bootloader
- fastboot flashing unlock
- fastboot flashing unlock_critical
- fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
- fastboot --disable-verity --disable-verification flash vbmeta_system vbmeta_system.img

- fastboot flash system system.img (must be arm64 A/B)
- fastboot erase userdata
-gsi should boot
- Do not format in TWRP format in twrp causes bootloop (https://forum.xda-developers.com/t/unofficial-twrp-3-5-2-for-infinix-zero-8-x687.4303243/)
- if you have issues like bootloop and stuck at boot you can try
erasing user data in fastbootd mod not in bootloader mode but in fastbootd mode
