Huawei P Smart 2019 POT-LX1 Bootloop

[xcjps]

Hello, No way to root my device all versions of magisk get bootloop below is the problem i think. My device has system.img erofs filesystem i guess. dmesg-ramoops-0.txt fdisk_list.txt

using twrp adb shell i can mount /dev/block/mmcblk0p64 manually to any empty folder but in read mode only,

~ # mkdir system_root ~ # mount /dev/block/mmcblk0p64 /system_root mount returns it as /dev/block/mmcblk0p64 on /system_root type erofs (ro,relatime,user_xattr,acl,lz4asm)

I found out the bug now I have fully rooted POT-LX1, the problem was xmount(block_dev, "/system_root", "ext4", MS_RDONLY, nullptr);

you have to change it to use erofs and then it will boot ok !

[xcjps]

Can you make magisk support EROFS filesystem for kirin710 pot-lx1 system partition? Because I cannot update to newest magisk build, I have to patch magiskboot using IdaPro everytime, can't compile myself at the moment.

I build a test one base on 19.1 You can have a test. I test it on my p30pro(erofs system), work ok. https://pan.baidu.com/s/1YlTOEQTgc3Ir2Hu6NS65eQ pw: 4l2o
