Update/Unbrick with unlocked bootloader - [9.0_B187]-[M20_PRO]

I'm already in 182 and magisk is not working. Do you mind sharing your ramdisk_recovery.img with me?

Look here

Boot with Vol + without USB Cabel

 

[Maddinuser]

Tried all of it, still magisk says "not installed". Flashed multiple boot.imgs...
When I start the manager it says it needs to do some additional stuff, when I click yes it fails.

Was asking here, since you seem to be on 182 as well. I think I'm just missing the right boot.img. But if that would be the case the phone would not even boot I think.

Here a patchet boot (Magisk) flash with
fastboot flash recovery_ramdisk patched_boot.img
unplug cabel and boot with hold vol +
then you can install Magisk and you have root acess!

Hope this helps.

It worked! Thank you very much!

Thanks,

after flashing oeminfo is nothing changed do you know why?

OEMINFO for Mate 20 series is encrypted and works only on the device it came with. So if you flash oeminfo from someone else's device, it will not help. It will break your phone, possibly permanently, unless you can restore your original oeminfo back.

You don't need to flash this

Would this method revert a phone back to its original firmware ?

Thanks guys. Followed the guide and have updated my Mate 20 Pro L29 to 182 and have root access

Only issue is Google Pay not working... Any tips on getting that to work? I've already tried adding it to Magisk Hide but I keep getting the "phone is rooted or altered" error.
Apologies if I'm missing something obvious. I'm new to Android (phones).

install safetynet from magisk modules

 

[DN38416]

Thanks. I couldn't seem to find a module called safetynet. But I managed to get it working by installing MagiskHide Props Config https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228 and changing to a certified fingerprint.

hey @auras76

if i understand correctly. If im now rooted and want to update to whatever firmware, i have to flash the other TWRP and do all the steps? including wiping the device completely? i hope there will be another way soon for updating, now it would be super annoying )

regards!

Yes.
Working to find a way without wipe.
Today I will upload my rom.

 

[sille]

so if i want to flash your rom, i have to do the steps with twrp? and after flashing i have to flash the root-twrp for root?
do you have a telegram chan for your roms?

No.
You can flash without wipe.
Twrp can be enabled from romcontrol app

nice, then im waiting on my 182 with root thx a lot

 

[Minotaur]

Is there any reason that just installing the Magisk-18.0.zip installer from TWRP can't be done, instead of flashing patched boot_img instead? Doesn't the Magisk zip file just do that anyway?
