I'm having the same problem, but with G900H. I have stock firmware, rooted and everything's working fine until suddenly, I have no network. I restart the phone and get network again but only for a couple of minutes.

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.

Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! 😁

I have the same problem.

Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.

Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.

I've tried *#0011# command here are results:

with LTE/WCDMA/GSM auto-connect:

with WCDMA only:

and GSM only:

imgur.com/8InhQWQ

It seems that GSM is not working at all.

At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch

(sorry for messed up links but I can't post to outside sites yet)
