[Samsung Galaxy S21 Guides, News] jrkruse:
Must Have An Unlocked Bootloader To Do This!

This An odin tar file I have created to flash along with stock odin firmware to automatically install TWRP recovery along with Disable VBMETA image. The tar file will also automatically install magislk root along with remove force encryption and patch bluetooth library file. It will also patch safetynet. No flashing of zips is required

Info For Bootloader Unlocks Can Be Found In Post 2

I Do Not Recommend Mixing Bit 1 With Higher Firmware!!!!

Unless Using Bit Safe Firmware That Is Patched

​

Downloads

SM-G991U/U1/W- Model

USERDATA_AIO_G991_FORCE_WIPE_NO_BL_10_10_21.tar.md5

This will force a wipe of data no mater what.

Full Odin 3.1.1 Bit1 Safe Firmware

G991USQU4AUFD_BIT1_SAFE.7z

This are odin files and will safely update all image files too bit 4 and keep bit 1 bootloaders. Unfortunately this will wipe data this is beyond my control as it seems to be a side affect of mixing firmware it causes data not to mount and therefore my AIO will format it. This is full firmware with USERDATA_AIO. This will put you on U firmware. Before flashing I recommend removing your google account and make sure in download mode you are not frp locked

If above USERDATA_AIO_G991_FORCE_WIPE_NO_BL is newer than the one in this zip use the newer one from above

TWRP Recovery Provide by @Mentalmuso

Be prepared to have your data wiped. The process tries to determine if you do or do not need to have data wipe but as a precaution just assume your data will be wiped. Especially if using U1 or W firmware
