[Samsung Galaxy S9  Questions & Answers] lupin 3rd:
Dear to all, I have a samsung galaxy s9 g9600/ds (snapdragon) with last official firmware android 10 and rooted with magisk and with custom kernel of klabit87. Even if the device is rooted, system partition it's read-only (seems that is related to Android 10) but if I try to install and execute systemrw ( https://www.systemrw.com/ ), I 've message "Fatal error! No super partition detected". But if I run "cat /vendor/etc/*fstab*" I'll get the following outputs

:/ # cat /vendor/etc/*fstab*
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

#TODO: Add 'check' as fs_mgr_flags with data partition.
# Currently we dont have e2fsck compiled. So fs check would failed.

so system partition is read-only and I can't use app debloat or Link2SD app. Somebody have found a solution to this problem ?

p.s.: the same utility throw error message about dm-verity and dm-verification: "ERROR: Data from 'vbmeta' does not look like a vbmeta header" ... so I can know if verity and verification are disabled ?

In the install of the firmware and root I have made the followings steps:

in download mode: Odin install Android 10 stock firmware G9600ZHS9FVA4 from here https://samfw.com/firmware/SM-G9600/TGY

check and disable oembootloader

Reboot

in downlaod mode Odin install TWRP

Reboot into TWRP (recovery mode)

Install multidisabler-samsung-2.2_klabit

Install forceencrypt_remover_Q

Format data partition

reboot to recovery

Install g9600_klabit_q_v6.3

Install Magisk-v26.1

reboot to system

there is something that I have wrong?
