Hi everyone, yesterday I unlocked and flashed TWRP on my CPN-L09 following this guide.
I successfully rooted stock with latest magisk, the only problem is that the fp sensor stops working.
After some research i've found this issue on magisk github: https://github.com/topjohnwu/Magisk/issues/862
Some users are reporting fp sensor problem with magisk 18+.
So I would like to try patching boot.img with magisk 17.3, do anyone knows a way to do it? As magisk manager tries to download the latest version.

Also I paid 15€ on easy firmware to download the FullOTA of my tablet so I can restore as it was. Really dont know if I can share a mirror with that file, and I have some credits that im not going to use so, if someone need the full ota I could share it. Again I dont know if sharing a mirror is against the rules so let me know.

UPDATE:

I successfully rooted my CPN-L09 (Mediapad M3 Lite 8 LTE) using a custom recovery that I made.
You can find the recovery here: https://mega.nz/#!9VdlRKaQ!jgUX6n9lIK1Ey-c9gk2fegHmjtgYtbPO6bum05Q5RCk
Ignore the errors while flashing, also I didn't test other twrp functions so be careful this is my first time making a custom recovery.

Steps for rooting:
1- Flash recovery using fastboot "fastboot flash recovery recovery_magisk.img"
2- Enter recovery power button + volume up
3- Flash this magisk version.
4- Boot and install this version of magisk manager.
5- Disable update check for magisk.
6- Enjoy root with fp sensor working.

As usual im not responsible if you brick your device. You do everything at your own risk!
