D820 After IMEI Repair only get Edge 2G Data Works [Solved]

[dj_mix]

4G and LTE does not work. I can only switch it to 2G and that works fine.
When I switch to LTE or 3G It goes back to 2G.

I think I know what cause problem I did a Network repair with this box but I left the dop down as UK. I'm in US do I change that to my country??

Also Can I write my orginal Security and QCN files back and start over??

I also made backup in esn pro of my esn before repair IMEI.

What do I attempt 1st?? repair netowrk again with correct country or return phone back using efs pro??

Hello.

To repair network, try these different solutions separately:

1. Make Repair 3G/4G. Re-start the phone, insert SIM/USIM card, wait 5-7 minutes and check network.
2. Try to write these QCN files (https://mega.co.nz/#!upRAlKqQ!_tslPZ...bG_m_qf2hItp4s, https://mega.co.nz/#!PgZmkTrb!T-t13P...768SV4OqNo-GqQ). At first, write Repair_1.qcn, then write Repair_2.qcn, re-start the phone, insert SIM/USIM card, wait 5-7 minutes and check network.
3. Try to write this QCN: https://mega.co.nz/#!zxR0GRgZ!cCIaqm...3mQ_sNiFJ_QBxI, re-start the phone, insert SIM/USIM card, wait 5-7 minutes and check network.


If none of these solutions won't help - You can write QCN/Security backups back into the phone via "Write QCN"/"Write Sec. backup" buttons.

Also, this can be HW problem.
