Hi everyone,
I bought my OPO in China last december and I have China Unicom as Service Provider.
I have correctly installed offical CM12OS, but the 3G network is not recognized by the modem of the ROM.It goes only on the 2G Network.
It is the same that happened with CM11s, In that case I had to flash a modem("signed_modem_34g.zip") into the Rom and then it worked.
I tried flashing "signed_modem_34g.zip" on CM12S but I was stucked in the bootloop.
What could I do now to make the 3G working again?
Thank You so much for the support.
Hello
I successfully upgraded my L04 to 6.0 b810, but now my phone cannot use 3g network (it has very weak or no signal), so it works mainly in 2g/Edge.
Are there any possible methods (eg. flasing proper modem, etc., im not really a pro in these) to revover my "signal loss" and get 3g signal strenght back?
Thanks for the anwers.

problem still exists
Downgraded my b810 mm indian to b521 lolli EU, but the problem still exists.
5-15 mins after reboot, H+ network flyes away, and the phone only works in 2G/Edge mode.
If i try to select only 3G mode in settings, it just cannot find any service provider.
please help me :crying:
Hello everyone. I just got an used s6 model SM-G920F
Ive had a few problems. System status is Custom amd when i tap on System Update nothing happens. And why thers an united arab emirates info in settings>about device. The other thing that annoys me is that no matter what network signal the phone is on it displays only 4G even when i choose WCDMA or GSM.
I tried to initialize it it with smart switch but it says device cannot be initialised. The phone is on marshmallow 6.0.1
Another thing that frustrates me is that i am not getting LTE cat 6 signal only standart lte. Should i try flashing a custom rom or stock rom via odin.
Try to flash a stock rom to fix those issues, probably your phone is on a custom rom right now

Ok i will. Thanks. But im not too sure. Does the g920f variant have lte advanced.
Try to flash stock rom for your carrier that you are using to have full support from carrier, like wifi calling and volte

Ok i will
in some Firmwares, the 4G symbol is actually HSPA+, and LTE data is displayed as LTE instead of "4G", but this happens only in certain firmwares, like canadian ones on a G920W8
I cant flash stock rom..
Try custom roms

My suggestion would be to try custom rom first, if issues still persist you can always go back to stock rom with odin.
