    Hello! I bought a used Samsung Galaxy J3 (2016). Well, I can not top up my account because after entering the code I get the message: "Connection problem or incorrect MMI code". Amazingly, if I want to check my account status, everything works. I tried to transfer the card to another phone and top up, and of course it topped up. Anyone have any idea what's wrong ??

    The seller swore everything was working, he said that the phone was new. Because it actually looked like new. With a box and other things inside.

    Hey, I noticed this problem in my S6 edge and S7 edge phones after removing frp by combination file. Appears after uploading one of the softches that I have in my database. The problem is solved by uploading another software.

    Yes, I will do it and let you know if it helped


    @Edit

    Where is the best to download ROM? Because I uploaded one but nothing has changed, nothing has even been reset.

    The Samfirm program will download the latest available ROM. Alternatively, search on Sammobile, there is a larger selection.

    Unfortunately, Samfirm did not help me, the rom I downloaded using this program cut my phone. Fortunately, I was able to save him. On Sammobile at the moment you can not download, and even if you can, I do not know if I will want to download at 15kbps.

    Did you provide the correct model? F / Fn? There is no option for SamFirm to download a bad rom. Several times I downloaded the rom for the F model and not once, I had no trouble - I skip the fact of the release itself, where, e.g. in July, it affected the phone very badly - I got some of these roms :D

    Yes of course, I downloaded three times and it ended the same way each time. In Odin at "recovery.img" she broke me with Fail and the phone is dead.
