FAQ
Q: Can i use this recovery with other firmware then mentioned in compatibility?
A: Only with same Android version or Rollback protection might kick in and you won't be able to pass the lockscreen.

Q: Where do i get vbmeta.img?
A: From here, download the one you need according to install instructions.

Q: TWRP can't mount data partition, what to do?
A: Make sure you formatted data partition.

Q: Phone is not booting even after 20 minutes
A: Try to reboot. If still not booting, make sure you flashed multidisabler zip / formatted data partition.

Q: How to format data partition?
A:

Q: Phone is showing only Samsung logo
A: Try to reboot. If still not booting, consider installing an older TWRP build or a more recent firmware. If you still don't succeed, post here some details about your device and previous firmware and we might be able to help.

Q: Why do i need to format data partition?
A: Because old firmware encrypted your data partition and new rom can't decrypt and use that content / root needs access to data partition to place misc files / phone not booting after flashing root until data partition gets formatted.

Can you attach a screenshot of Odin and eventually tell me if you see anything in particular changing on phone screen? It should throw an error or something below the usual download mode lines. A pic of phone screen would be nice but i'd assume it's your only phone..

Can you please check Kg state line from download mode? What's written there?

 

[edsoedso]

I installed twrp but it seems that it does not read the internal storage.

 

[edsoedso]

Can you please check Kg state line from download mode? What's written there?

And how to flash the multidisabler? it seems that everything is encrypted and is impossible to locate it in twrp?

 

[edsoedso]

I found it!
1. enter into TWRP (after flashing twrp.tar and Vbmeta.tar via odin), format data and reboot again in TWRP
2. Being in TWRP, transfer from PC to your phone multidisabler.zip and magisk zip.
3. flash them both
4. reboot system

That is all!

I'm still trying to find the issue, for whatever reason multidisabler needs a second flash to work as far as i seen on my device. So for now please flash multidisabler 2 times in a row, until i find a better solution to this.

Thank You very much. It worked!

 

[ossage]

A big thank you, it works fine.

 

[ae01]

hey.
i did everything from this guide, and i got root access+twrp installed.
the problem that i am facing, is that i canot install anything from twrp, due to insufficient space.
the system size that twrp is reading is only 8384kb, so every installation of gapps is failed.
i tried to wipe ,format data, and changing the file system, but nothing helped.
please give me an idea how to solve it.
thanks.
