Is rooting possible (need it to try and hide custom rom from MS work apps)? More of a Lineageos question but tried Magisk by following this (
https://www.androidweblog.com/root-xiaomi-poco-f4-magisk-without-twrp/) but that I initially didn't flash boot_b (flashed "boot" only which the output showed "boot_a_ was only flashed) and it boot looped when rebooting after that.
So I then entered fast boot again and tried to flash "boot_a" (completed - again) AND boot_b but boot_b aborted with "fastboot: error: boot partition is smaller than boot image". Stuck in boot loop after that when trying to boot up. Would re-flashing the original boot.img from this Lineageos build likely restore things so the apps/data I had installed so far are installed? I messed up in any case as Magisk recommends wiping apps/data before flashing it but just trying to avoid rebuilding if possible.
Edit: OK, so now I understand the purpose of the two slots (wish they weren't referred to as "partitions" on some sites). I've likely hosed both. But I would like to know if Magisk is supported by this Lineageos build before rebuilding?
