Hello,

I have problem with patch my boot.img with Magisk manager. After patching I got error : "The phone is not running Samsung's official software". After flash again stock boot.img everything works.

I use Odin to flash.

I tried to install unofficial TWRP from other thread but I got SVD Fail and vbmeta errors during boot.

Somebody have any idea how solve this problem?

Model : SM-A127F/DSN
Baseband version : A127FXXU2AUG7
Android 11 (UI 3.1)

Info from download mode :
KG STATE : Checking
FRP LOCK : OFF
OEM LOCK : OFF(U)
Secure Download : Enabled
RP SWREV : B:2 K:2 S:2


I found similar situation on movie :
But for me recovery mode and factory reset not solve problem. Phone stuck on "Samsung's official software" and reboot after a few minutes.

Best Regards

I have same phone A127
Do you rooted your device now ?
If yes how do you root device ?
And thank you
Hi, Yes I have root on this device !
It's very simple, but official Magisk have a bug which prevents the device from booting properly and your phone will be stuck with in bootloop.

1. You must get custom patched Magisk (jn attachment) - from This thread and install it on phone.
2. Get your original firmware from : https://samfw.com/firmware/SM-A127F
3. Unpack your firmware and upload AP_XXXXX file on phone and patch it with magisk.
4. Flash with ODIN and done :)

You have full instruction : Here but I recommend patch full AP_XXX file not only boot.img. Full AP patch It will allow you to turn off DM-Verity immediately and trouble with vbmeta.

Thanks for this.
I just bought this phone and looking forward to building a custom kernel for it.
