Samsung J320fn MDM unlock

[Legija]

Start eMMC plugin, click "Parse connected memory".


Right click on "EFS" partition and select "Inject data from external file".
Select bin file from attachment.


Click "Flash partition full".


I manually edited knox activation, so maybe thats enough.

Is set something wrong? thnx







Sorry continue work, flash ok, but after conect to wifi first actualizing samsung aps, next knox.. phone locked now

Start plugin, click parse connected.
Double click persistant and persdata partitions, then click erase.
After that double click iserdata and click erase, since this is bog partition you dont need to wait for finish, 10% should be enough.
Afyer this write efs again, reboot to bootloader and flash firmware.

The phone does not enter the download mode, a resurrection will be required...

[Legija]

Ok,
I am not sure if phone is identified on samsung server by its sn, or there is some settings on phone which could be changed.


Erasing userdata and other two partitions would 100% clean phone from any previously enabled settings.


I just think here is only route to install custom rom, or change phone imei/sn.

[djuce]

Imei changed first - no change
S/N - my boxes not supported this


currently phone is dead,
probably damaged pins - communication error

[Legija]

Too bad. I hope You can find whats wrong.


EFS contains phone SN, which is probably used to identify phone on Samsung server.

[djuce]

The phone is already alive but not flashed / probably hidden /
tomorrow we will continue .

[djuce]

The NeverEnding story continues:
Phone locked now after connect to net...

I try to fix SN but but i don't know if i don't lose the signal.

[Legija]

Let me edit phone SN for You, you can restore it from backup in case of problems.


Attached is EFS with changed SN (if that is phone sn in first place )

[djuce]

Nothing, no change ...
I'll try custom rom / that's the last chance. I'll throw it in the trash /


Thank you for everything..

[djuce]

The end )

[Legija]

So custom rom worked.


Seems that phone is identified on samsung server by CPU SN, hence not possible to hack it.

[djuce]

I found more information about mdm, but I quit...






Just a moment...

I have removed MDM on 2 sm-j701m. To remove I rooted both devices, then I installed app2sd and there I processed to uninstall all apps that says Knox or anything that I thought was related to the previous account, after I think i reprogrammed and device worked fine, but they can remain rooted
