[Samsung Galaxy Note 8 Questions and Answers] anthoniarsg:
Hello,

I negotiated a Galaxy Note 8 (SM-N950F/DS) through a site of collective purchases in Brazil, with invoice and all the accessories.

I did all the tests in the device and I decided to buy it, because it seemed reliable.

The device already had the factory settings, but with Android 7.1.1.

I activated automatic update in order to upgrade the android to 8.0.

I received the update and installed it. When restarting the phone, I started the settings normally, I was able to configure the Samsung Account, but when I was starting the configuration of the Google account my phone blocked.

After trying several unlock passwords, I made contact with SAMSUNG which instructed me to send the device for local service.

When I arrived at the service it was verified that my device had "transport block" and who is responsible for unlocking the device is the store in which the device was purchased.

I went to the store that was described in the purchase invoice and there informed me that the store does not perform any kind of unlock or block, so I could not solve the problem.

After several discussions with Samsung and the store, it was verified that my invoice was exchanged and that it was possibly not true.

It was from there that I realized that I was deceived by the seller of the device, because when I try to contact him, my calls do not complete and he blocked me in the social networks.

The only information I have about him is his name and the phone number that should have already been discarded.

Anyway, I realized that I would have to try on my own. Because of this, I am doing this post. I apologize for the long text above before passing the technical information, I had to explain what happened, because I do not want to pass as a thief.

After doing several research I found that the lock was being triggered by RLC.apk which is located at "/system/priv-app/Rlc/Rlc.apk" in stock firmwares.

I found an instruction that guided to freeze the performance of this app with application Ice box v3.1.9.1.

I tried the instruction, but it did not work on devices with Binary 4 (which is my case). The device continues to locked.

I talked to some technicians who told me that this is a block known as SEDA_LOG or DNP 0001. There are some companies that unlock remotely, but it does not have support for Binary 4.

With rom COMBINATION I can use some applications installed by adb, even my data network works perfectly.

The IMEI is normal, unlocked, and is out of the blacklist.

Other information is that the RMM State is Lock, FRP ON, OEM LOCK ON.

Also, when the lock screen appears a few times the message "Silent Log is not allowed for commercial version, please get the EM token".

Through the Samsung Account I can make the phone ring and even locate it, but it does not unlock.

Some failed attempts:

- flash a rom from another region (the device region is ZTO, I tried O2U)

- wait 7 days for the RMM State to disappear (not disappeared, continued locked)

- freezing the RLC app

- enter several PINs to try to unlock.

- login with my samsung account on rmm.samsung.com to try to unlock rmm, but I can not access.

If anyone can help me, or can guide me in what to do, I am very grateful.
