Failed to root SM-N9200, need help.

[BadWhoLala]

Hi,

I'm trying to root the phone of a family member, but I got into a LOT of trubble.
According to the label behind the phone, it's SM-N9200, I attached the label without the IMEI.

After reading and learning, I decided to flash recovery and kernel inorder to root the phone.

1. So I flashed TWRP using odin based on this tutorial:
https://twrp.me/samsung/samsunggalaxynote5.html
I picked the version of: "China & China Duos (SM-N9200, SM-N9208)"

2. After flashing I got into recovery (without loading system), and flashed some kernel that should fit to this phone.
I picked the newest kernel in the forum:
https://forum.xda-developers.com/not...-n920-t3396722
But I think that this was a mistake, I don't know if this kernel fits to stock system.

The installation of the kerenl took ages (2-4 hours), the thing that took so long was the dealing with the system partition for the rooting.

3. Tried to boot into system, right in the start above the logo of samsung galaxy note5, I saw in red that the kernel is not seandroid enforcing.
But the system never booted, it just stuck in the black screen with the logo of samsung galaxy note5.

4. i tried another kerenl:
https://forum.xda-developers.com/not...ougat-t3574986
But it didn't work and the phone is still it stuck in the black screen with the logo of samsung galaxy note5.


Now I don't know what to do...
I hope I didn't damaged the system and it's still recoverable.
I can't earse the phone, we want to recover all the data including all system.

you should have made a nandroid backup before flashing the kernel. a nandroid backup is a complete backup of your phone, incase something like this happens. as long as you can get into recovery you can always restore a nandroid backup. well, let's make this a teaching lesson.

so looks like not many roms or kernels supports n9200 variant of the note 5. you have to be very careful on what you flash. kernels and custom roms are very device specific. you need to read the op and the entire thread for each custom rom or kernel, before flashing.

the only thing i can think of is to flash a firmware for your device. go to sammobile. it might unroot you however, but i'm not 100% positive.
