[Samsung Galaxy S10 ROMs, Kernels, Recoveries, & Ot] PiCkLeS:
By clicking on the button below you will get a set of instructions, step-by-step, on how to install Ians excellent work with TWRP as a recovery for your device and John Wu's root via Magisk.

This is not the fastest or most uncomplicated tutorial to do this. It is, however, made to make sure as many as possible succeed. So if you feel that a step or two is uncessesary, this tutorial is probably not for you since you most likely already know enough to just go by Ians more direct instructions. So dont PM me with tips on how to simplify these steps, I already know about that and that is not the point of the tutorial.

The instructions are intended for:

The user that either is completely new to this world but have managed to get an unlocked bootloader beforehand

The user that just want to have some instructions to follow to

not forget a step in the process

Please note that the tutorial should work just fine for the S10E-device, but there might be another set of key combinations for your device, please take care to understand what you need to do in specifics to do the same presses of buttons.

It is strongly encourage to flash lates stock firmware and do a complete clean system install before using this tutorial. However, if you know what you are doing, it will work fine with an already rooted system as long as you have the latest Canary build (both magisk and magisk manager) on your device when patching the TWRP-image and the firmware AP-file per instructions below.

Where ever you decide to start, know that your device will be wiped and you need backups for your relevant data before you begin.

These instructions are ...

.. an "add-on" till John Wu's Magisk solution that will make your device rooted with Magisk and having Ian Macdonalds TWRP-recovery

.. for those who have already an unlocked bootloader - DO NOT attempt this without first making sure you have "OEM Unlocked" enabled

Step-by-step guide:

A) Follow John's instructions HERE until you get to step 5, then return here

B) Download latest TWRP-image by Ian Macdonald for your type of device in the first post in this thread

C) Download latest multidisabler-zip by Ian Macdonald and copy it to your SD-CARD - download here

D) Copy the TWRP-image to your device and do the same as you did with the AP-file in Magisk Manager (Install->Install->Patch file and choose the TWRP-image)

E) Copy the patched TWRP-image and magisk_patched.tar to your computer

F) Rename the patched TWRP-image to "recovery.img" on your computer

G) With your own choice of program on your computer, open the "magisk_patched.tar"-file, remove the existing recovery.img and replace it with your newly patched recovery.img and save the tar-file

H) Boot your device to download mode

I) Go back to John's instructions and IGNORE step 6 and DO step 7 and come back here!

J) We now need to factory reset our device:

-> Press Power + VolDown for a few seconds to get out of download mode

->

AS SOON AS THE SCREEN GOES BLACK:

Press Power + Bixby + VolUP and HOLD THESE KEYS FOR A LONG TIME until you see the bootlogo of TWRP, then release the keys

K) In TWRP, install your downloaded multidisabler-zip from your SD-CARD and DO NOT REBOOT

L) In TWRP, format data (not only wipe, choose specifically "Format data" and write "yes" and go ahead and after DO NOT REBOOT

M) In TWRP, go back to the start screen - choose "Reboot" and choose "Recovery" AND NOTHING ELSE - DONT touch any keys on the device

N) Go back to John's instructions and begin from step 12

O) All done - you know have a rooted device by Magisk, with TWRP as recovery - enjoy and be sure to thank Ian Macdonald for the help with TWRP and John Wu for Magisk root!
