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.

I notice I have bootloder on my device that I didn't install my self. I'm just a average user and have no clue how this was put on my phone. Also all of my apps are older versions an I'm unable to update them. I need help figuring out what's going on. Anyone please help!!!

Many thanks for the latest update mate

1. Can I use this TWRP version with any custom ROM (e.g. Dr. Ketan ROM)?
2. Do I have to flash vbmeta.img, even when I have that custom ROM?
3. Is there a twrp.img for N986B that supports Android encryption, since right now encryption is somehow disabled after installing Dr. Ketan ROM: the lockscreen password has no effect and I can access and read all files on all partitions with the TWRP file manager !

1. Yes as long as the rom dev doesn't have other instructions regarding the recovery used (i.e. LineageOs)
2. No, you already have some nulled vbmeta flashed since you are running a custom rom.
3. Nope, since samsung uses proprietary encryption. You can however preserve data encryption in the rom (talk that with the dev of your rom), but this will make it unreadable by twrp in any conditions. Please keep in mind that Samsung fw may not like it and it can trigger a data wipe without warnings.

Re. 3.: With "fw" you meant FRP? But when I have root I can simply erase FRP and most Knox and other unwanted bloatware apks on /system, /product, /prism etc. ?

Btw. do you know if there is there a possibility to completely remove the Samsung ROM and replace it with a plain Android? You may lose one hardware driver for the "Sasmung Pen" but everthying else should work..?

Fw as in firmware. Regarding plain android - search for AOSP based projects, i'm not aware of the active developement so i can't properly advice you in this matter.

i am trying to root my note 20 u device. when all succesfully start from magisk module and twrp, i find the screen flicker for a second every 15 seconds. I'm trying to figure out which app the problem is from. looked in screen recorder and found the problem. apparently from system ui. then start again from the initial step one by one. and the cause of the problem is after installing twrp. I'm on Ui5.1 N986B exyns. i feel twrp has a bug

 

[MasterEsno]

Now im use back stock recovery and problem has gone

 

[Sn33z3x]

Hi it's been a while since I last install TWRP on SS phone, it got complicated now I have few question, can you help answering?

1. Open Odin v3.14.1 and place the downloaded TWRP .tar file in AP tab, downloaded vbmeta .tar file in CP tab and click Start - once you press start grab the phone and press vol up + power to force it boot straight in TWRP after flashing

- For this, do I have to press the key combo 1 time only after clicking Start Odin or I have to hold till the progress done?
2.

!! Only if coming from full stock (magisk patched) firmware

• In TWRP home screen press wipe - format data - yes
• Download and flash multidisabler-samsung-3.* zip to disable security and encryption.

- I never install TWRP on my phone, do I have to follow this step?
-If yes, do I have to install that file right after TWRP first boot (when odin completed flashing)

And finally, does it support android 13?

Thank you so much

 

[tonyja77]

TWRP 3.6.1 support android 13(one ui 5.1) or not
