[Samsung Galaxy A71 5G Guides, News, & Discussion] droidzer1:
When you decide to unlock your bootloader these directions will help you be prepared and will avoid tying up afaneh92 too much as I know he barely gets any time to sleep with all that he does :) Since I'll assume you are not unlocking your bootloader for fun of an unlock the directions below will help you get Root and TWRP installed. TWRP is the easiest way to install Magisk and get root.

First you will want to do a complete backup of your phone. I suggest Samsung Smart Switch or MyBackup Pro or both :)

Then you need to get your phones DID number. You can see it on the download screen. Easy way to get into download is to turn off your phone, then hold volume up and volume down and the plug in USB cable to your computer (charger may also work). Then when you see the aqua color screen hit volume up to go into download mode. There are a couple other methods listed on the page afaneh92 has in the link above.

Save the DID number and it will be good to take a picture of the Download screen also as afaneh92 may request that.

Make sure you have the patched version of Odin from here:

Also get multidisabler.zip and vbmeta_disabled.tar if you don't have it.

Multidisabler.zip can be found here: https://xdaforums.com/t/pie-10-11-system-as-root-

Also get the Magisk.zip file from here: https://github.com/topjohnwu/Magisk/releases/download/v21.4/Magisk-v21.4.zip

Then get on Telegram to contact afaneh92 from his link for his channel in the link above. Once you make payment he will get the .tar file for your phone. It can be just a couple minutes or a day or so I believe depending on his source being available. Mine only took a couple minutes. Once you have the fix file

for the bootloader unlock you will use the patch Odin to flash it to the AP section. Upon reboot the phone will take a little while to start up as it's like a factory reset and your data is wiped.

After you have gone through the phone setup wizard you will want to reset Odin, go into Download mode again and flash vbmeta_disabled.tar to the USER_DATA section in Odin. And if afaneh92 has TWRP available you can flash it into the AP section at the same time. Before pressing start in Odin be ready to quickly press volume up and power button once the phone reboots and the screen goes black. The release when you see the Logo. The you will be in TWRP.

Use adb to push multidisabler.zip onto your phone. Since data is encrypted at this point there is no use in

copying it there ahead of time. Just use "adb push multidisabler.zip /" which will copy it to root of phone storage where you can see it with TWRP. After flashing it do not wipe cache / Dalvik.

Then in TWRP choose Format data and type yes to confirm. Then reboot TWRP into recovery (TWRP)

In TWRP flash multidisabler.zip Then format data and answer Yes.

Then the best way to install Magisk is to flash it now from TWRP with "Install".

Reboot and check whether Magisk Manager is installed. If for some reason it isn’t installed automatically,

manually install Magisk Manager and with Wifi on allow it to do any updates.
