Re
Maybe first of all you two write the steps performed for flashing Lollipop Roms? I've tried all the Lollipop Roms compiled for SXS and nor,ally I used to do this way:
1. TWRP recovery (but CWM also worked)
Install TWRP recovery in FOTA partition using Terminal apk provided your phone is running on 4.1.2. kernel supporting TWRP recovery. Flash kernel from ROM zip file prior entering TWRP (this step helps avoiding an error like "update binary...").
2. In TWRP recovery - Advanced - wipe everything but sdcard. In Mount section unmount everything but sdcard.
3. Flash the ROM and wipe Cashe&Dalvik
4. Flash appropriate GAPPS, wipe Cashe&Dalvik and reboot.
that's all

U try to install the x86 version of Xposed on M9, which is a arm64 system.
Get the ARM64 version!
Also, check SDK version: SDK21 is Android 5.0 (Lollipop), SDK22 is Android 5.1 (also Lollipop) and SDK23 is Android 6.0 (Marshmallow).

This one has another error, your system partition is not mounted read&write.
U should do that in TWRP.
Before that, do a backup including a system image, if u are stock, this will help if u go into trouble.
Good luck!

TWRP and "No OS installed" and failed to mount /System (Permission denied)

As explained in an other thread i got this issue :
with TWRP-offain and original one downloaded from TWRP website i received this error message after installation attempts of different custom ROMs
No OS installed
I wiped System and Data partition on each A and B slots and then tried to install on each slots some custom ROMs
At the end of each installations i received also this error message :
failed to mount "/System" (Permission denied)
How can i solve the issue ?

You need to use this twrp. Then it will work. About twrp errors: just ignore...

I've already used also that TWRP version
twrp-installer-daisy-3.3.0-0-offain.zip
KO

Cannot Root Magisk Canary On Samsung A505F

I have a Samsung A505F running android 10 (custom rom = HavocOS 3.1). Whenever I try to flash magisk canary, I get this error.
Code:
- Mounting /system, /vendor
! Cannot mount /system
- Unmounting partitions
Updater process ended with ERROR: 1
Edit: Fixed by installing TWRP which installs Magisk by default, but magisk manager isn't there. Also, if you get the one from Samsung A50 telegram, random reboots is fixed.
