[Samsung Galaxy F22] Akhil99:
I would like to thank TeamWin for their amazing work!

I saw that the newer Samsung MediaTek phones were not getting any sort of love, so I bought one myself to kick start the development.

I have already made TWRP for M32 & A41 and thought why not add support for a sister device.

KEEP IN MIND THIS IS A BETA BUILD, expect bugs!

TWRP is the obvious choice as it is reliable and trustworthy with frequent updates and patches.

INSTALLATION:

Odin Method (Windows):

Step 0: Unlock Device Bootloader by toggling the OEM Unlock option in Developer Options. Device will reboot to Odin mode and will prompt you to long press volume up, device will then unlock bootloader and perform a complete factory reset so make sure to backup any data.

Step 1: Download the unofficial TWRP image from the link attached below.

Step 2: Put the device in Odin download mode by holding VolumeUp+VolumeDown and inserting USB cable after the device is completely shut down.

Step 3: Select the downloaded recovery.tar in AP slot and vbmeta_disabled_R.tar in USERDATA slot, connect the device to PC, go to options and untick "Auto-Reboot"

Step 4: Click START and the Device will get flashed, Odin will say SUCESS!.

Step 5. Exit Download mode by holding VolumeDown+PowerButton and then immediately boot

into Recovery mode by pressing VolumeUp+PowerButton.

Step 6: Congratulations, you have installed TWRP latest for your F22 4G, to access the system now, you need to perform some additional steps.

Step 7: Open up TWRP terminal and then type in "multidisabler" and then perform a full factory reset again by going into "Wipe" -> Format Data -> type "yes"

Step 8: Now stock ROM should work fine with TWRP!

Heimdall Method (Linux):

Step 2: Put the device in Odin download mode by holding VolumeUp+VolumeDown and inserting USB cable after the device is completely shut down.

First time you boot into TWRP, don't forget to backup your EFS, Secondary EFS and NVRAM! Go into Backup and select "EFS,", "Secondary EFS" and "NVRAM" and backup to preferably MicroSDcard and copy it to your PC in case you need it if IMEI corrupts.
