Samsung Galaxy S22 (Exynos)
-
Unlock Bootloader (Enable OEM Unlocking in Developer Options, power the phone off, hold Vol+&- while plugging in to your PC)
-
Download the latest firmware for your device (You can use e.g. Samfirm - google it)
-
Extract the archive, open up the super archive via 7Zip Z-Standard (NOT THE REGULAR 7-Zip), extract the recovery archive and then extract that one to get your own recovery.img
-
Patch your recovery image (you can patch it with Johnx22's Patch-Recovery Tool
-
To flash the patched recovery, download Heimdall
-
Extract it and put the patched recovery.img into the same directory as the heimdall.exe (or the Linux equivalent)
-
Follow the README file, specifically the "Driver Installation Instructions" , in my case I had to replace the SAMSUNG USB device's with the WinUSB one (make sure it's NOT the "modem" one)
-
After that, try executing the following command within the root of Heimdall's directory:
heimdall flash --RECOVERY <whatever your patched image is named>.img -
An alternative is renaming the patched recovery image to 'recovery.img', putting it into a .tar archive and flashing it via Odin into the AP slot.
-
Make sure to hold the power button and Volume Up as soon as the phone starts rebooting, otherwise the patched recovery will be overwritten by the Samsung one as soon as one boots into OneUI
-
After entering recovery, choose "Enter fastboot"
-
Flash an ARM64 A/B GSI with fastboot:
fastboot flash system image.img -
Go back into recovery and Wipe Data and Cache
-
Reboot!
- Download and install 7-Zip Z Standard
- Open the AP firmware file (that you'd usually flash via Odin) with 7-zip ZS
- Extract the boot.img.lz4
- Open the the boot.img.lz4 with 7-zip ZS
- Extract the boot.img
- Download and install the latest Magisk Manager apk
- Copy boot.img to your phone
- Open the Magisk app
- Choose "Select and Patch a file"
- Pick your boot.img
- Take that patched image from Downloads and put it on your PC
- Boot into fastboot via the recovery
fastboot flash boot <patched boot image name or whatever>.img- Reboot
- It will bootloop so make the phone go into recovery once more, where it'll offer you to Factory Reset since the phone is having a seizure
- Perform that factory reset and reboot

**In the stock camera, everything should work (except the nightmare fuel audio from video recordings) but the quality is ass. With GCam, however, you get better quality at the cost of instability that you yourself have to tinker with to reach some stability: https://www.ytechb.com/google-camera-for-samsung-galaxy-s22-plus-and-s22-ultra/
- I personally recommend the 8.4 one (with its config and lib), and make sure to find and enable the "Exynos fix" to remove the color banding from photos.
- As an alternative, try MGC_8.1.101_A9_GV1zfix_MGC.apk along with This XML config (double tap between the shutter button and the gallery button while in the camera app in order to apply the config)
Feel free to edit if you find a better port/config.
