N910H The phone displays available networks but doesn’t register on it [Solved] - GSM-Forum

Hi support.

I know I am not the first one to post about this issue. I have searched for solution but couldn't find any successful post. I have Samsung Note4 n910H running on 5.1.1 rooted. The phone displays available networks but doesn’t register on it. Manually selecting networks says unable to connect try later.

The phone came to me with bootloop. I understand that someone tried to write different csc and couldnt pass hidden.img. I had to flash the same region firmware (N910HXXU2COJ4_N910HOJV2COJ1_AFR.zip) but every time stop on hidden.img. Tried more than 5 files ( CSC = AFR ) So To solve it I had to flash CF-Auto-Root-tre3g-tre3gxx-smn910h.zip.

Now phone does not register on network, I’ve tried to write different compatible Cert files (Cert-sm-n910c-355025068585692, Cert-sm-n910c_355025068700887, Cert-sm-n910c_355025068700770, Cert-sm-n910c_355025060390000 ) but still same problem.

Hello.

Try to different Cert files one by one. IMEI of Cert files, which You've used might be provider's "black" list.

Problem solved.
By flashing security from a working phone. and again restore its original security.
