Hello all..,
my Atom experience a critical problem, it cannot connect to any GSM provider. with any SIM card inserted (even new one) it will keeps on searching the network, cannot connect.
when doing manual setting, it can list all the GSM provider (probably from the previous setting when still works) but after selecting the correct provider, the message says: cannot register to the network.
any other feature from the device or OS still works fine. even the wireless still working. it just can accept anything from the radio (incoming/outgoing call or messages)
I checked in the device to O2 service center and they opted to replace the mainboard without even checking/opening the case to see the internal parts.
I've tried soft-reset, hard-reset with no success. Even tried flashing with the official latest ROM from O2, still with no success.
Help..
is there anything I can do to repair it? any particular procedures?
Thank you very much.
cannot connect to GSM provider also

Had some problem like yours just now. No matter how I flash my phone, changed my modem, it is stuck at 2G (Edge). Then I went to Settings>More networks>Mobile Networks and changed my network mode from LTE/WCDMA/GSM(auto connect) to WCDMA/GSM (auto connect) and then it becomes H+ again! Hope it helps!!
Unfortunately, not the solution. I m selected just a WCDMA I get the message "no network" I load different roms but Unfortunately, the same result
