Hello
Mohd Masab
It's my first Samsung .I had 4-5 Sony ,easy to root ,a Doogee S90 (NEVER BUY THAT !).
Is your method safe ,have U seen bad effects ,what fonctions did U lost ?
Bye .

Okay, so I completed the whole process, here are my observations:

The method provided above almost works. The problem is, that everytime you reboot to system when you are not rooted, TWRP will encrypt your files. So the solution is, that you have to format data and then install dm_verity and Magisk after each other, without a reboot! After that, you can boot to your system and set up your phone.

I did what you said but still encrypts after reboot. Latest Magisk.

Hi, I am having problems with internal storage, I can not create folders and there are applications that I can not download, any solution?

 

[abraxasboot]

Could someone tell me if it is compatible with the November update CTK1?

I have managed to root the phone, you can install everything and configure it, but after turning off the phone, I can't start it does bootloop, and it returns to the prompt "The phone is not running Smasung official software ..." never finishes starting? What do you recommend me to do?

I reloaded the original rom and did the procedure again, taking into account the clarification of installing install dm_verity and Magisk after each other, without a reboot, and everything went well!

 

[fleafred]

Hello abraxasboot !
So,for you ,the only problem was that U had to flash the files one after the other without rebooting ?
No other problem since that ?
Is the phone reacting well ?
Where did U find the official rom ?
Thanks and have a good day !

I was unable to flash and reboot into TWRP recovery after applying the official Samsung update from March, which updates Android from 10 to 11. Reboot into recovery would not work and I would always end in a boot loop.

I had to downgrade to Samsung's official Android 10 and used the binaries from January for that: https://samfrew.com/es/model/SM-A515F

After that, flashed TWRP again and was able to boot into recovery right away as it should be

 

[antuanix46]

If I follow the steps and flash twrp-a51-3.5.0_10-1_ianmacd.tar file using Odin I get an message:
'Only official release binaries are allowed to be flashed (RECOVERY)

The phone was recently purchased from Samsung official store, and has android 10 official firmware from feb 1st installed

Any clue please?

 

[Benjamin0702]

hey guys i used a lyf wind 1 to flash lineage os using twrp ..... so i wiped the previous os and unknowingly flashed another unsupported version of twrp ...when entering to recovery menu its all blank .... now i have no os and recovery ...... i couldnt flash stock rom because my device is not recognised as qualcomm port .............

pls any help ????

 

[danofaster]

I have a working 11R twrp and all the DRM passers mejestics etc. to run.. you can boot the os after that that is the standard Samsung OS. np u can install LINAGE os 18.1 Andys march release, the Mejestics meaning u can patch root without Needing to part the orignal Firm and copy boot.img over. etc
