Thanks for the share, would be appreciated if you can mention how to update over OTA when we have root the phone. Thanks.
The reason it's not mentionned is simply because we can't, we just need to download latest firmware and patch it with magisk.

topjohnwu stated ( and i tested it myself ) that if we flash the latest OTA it will brick the device, which is logic.

We need to patch the latest firmware with magisk, if we go from a rooted environment to a non rooted it will brick.

I hope i cleared your thoughs. :cowboy:

Okay, so let's say if i get new OTA push notification, i download it first online and then i follow your root tutorial to update it with magisk included?

exactly, download the needed firmware and extract the AP file and put it in the download folder on your A71 device, then patch it to obtain a magisk_patched.tar file to flash in odin. :p

(Snapdragon 730).

-Xiaomi Redmi K20
-Samsung Galaxy A80
-Poco X2
-Realme X2
-Oppo Reno 2
-Lenovo Z6

ill ask samsung open source release center to provide the source code for this device. (i'm an A70 user not A71).

just that your knox bit will be tripped (0x1).
Thank you, and got another question (sorry :D), on your booting instructions, you say that to boot using using magisk we need to press vol+ and power, but will that be possible to boot as usual with power button and boot with magisk by default ?

once twrp is released yes (if someone port it).
there is another method but that's another story.

It is not working :(

I downloaded hungarian firmware from frija, copied the AP file to my phone, patched with magisk, copied the patched file to my computer, booted my phone into download mode, flashed the ap file with odin (and yes i unchecked the auto reboot), and after it finished, I pressed the volume down and power button to reboot, and when the screen went off, I quickly changed to volume up and power button and hold until the bootloader warning appeared, and realased all buttons. After it booted, i opened magisk manager and it says magisk is not installed :( what can i do? ( and yes, I unlocked the bootloader)

I've tried rooting several times to no avail, I've unlocked and flashed everything with the patched magisk setup, I'm using the SM-A715F BTU firmware as that's what my phone was beforehand

When i try and do the volume up boot then release at the warning screen it just does a reboot cycle and never boots I have to force it it shut down and boot normally

I cant even restore phone to a point where SafetyNet validates so no Pokemon Go and such

Ok ladies and gentlemen I finally got it working, and here's what I had to do

You'll need to install 7zip or something that handles TARs and LZ4 that you can grab from github it was the second result on google for me

Once you've patched the AP file in Magisk Manager and copy it back to your pc, Open up that tar file and delete all files except recovery.img and vbmeta.img

Then open the original prepatched AP file in 7Zip and extract the boot.img.lz4 then take that file and drag it onto the lz4.exe from the lz4 utilities

you should now have a nice clean uncompressed boot.img, put that back onto the phone and patch it with magisk manager, you should now have magisk_patched.img copy that back to the pc and rename it boot.img and put it in the tar file from earlier so you should have boot.img recovery.img and vbmeta.img

With just these 3 files in the tar you dont have to worry about wiping your data again and it will patch pretty fast

Open up ODIN again and select AP and choose your new tar file and flash it

Then shut down the phone fully and power it on while holding vol up till you get to the warning screen about the unlocked bootloader let go of vol up and press power to continue and you should find that it boots properly now and magisk manager will show that magisk is installed.
