I purchase 2 of these phones ( Korean variant ) And live in Australia.
the both had crap 3g reception so I installed Cloudy rom and G3 roms

On one of them I reflased the factory ( Korean rom ) ( Downloaded img ) and suddenly had a 3G symbol.
They both now have G3 roms installed and have tried installing the Korean modem and
still have crap reception.
Just wondering if anyone out there has a solution ?

[Q] Help! Problems with lte and mobile neteork

Hey guys, I really need your help now... I tried everything I could but couldn't fix the problem.
So, I have LG g2 d802, and I live in east europe, Georgia, near turkey.
I upgraded my phone with kdz to stock lp, i didn't like it, so i downgraded bootloader and flashed blisspop.
I don't. Really remember when it started, but right now I can not get lte to work.
Also, mobile internet and generally reception is really weird. It has some drops, mobile network most of the time doesn't work, and reception is bad and laggy.
I kinda flashed another modem, radio, baseband nothing seems to work. Or may be i didnt flash correct ones, and i dont even know which one is correct...
Please please please!
Anyone has any suggestoons?

Low wifi signal

Hello
Recently got a refurbished S4. Actually i can't know the exact model.
In download mode. It says it is the L720T model (sprint). But i can't instally any sprint rom.
I could install int i9505 roms (jfltexx). I tried updating lollipop modem & bootloader but i could only install Sprint modem (Updated from L720VPUGOH1 to L720VPUGOK3)
But the real problem is that I got very poor wifi signal. When near the router,it works. As soon as you walk bit away ,the signal drops significantly.
I'm still wondering wether it's a hardware or software issue. And i'm not sure about which version i got if i wanted to flash stock firmware. How can resolve this ?

Signal Issues: Hardware or Software?

Poor phone signal.
I have reinstalled the latest official firmware, then a custom rom again. The imei matches the original. Any other ideas please?
Do I need to replace the antenna?!
Thanks...
Correct modem and CSC for your network ??
Hello,
I have the same problem, I have the latest ROM for my country and the good CSC (my phone as Lollipop) .
I don't understand why I have this problem, and in my house, when I was under kit-kat 4.4.2 at the same place I have a good signal, but now I have some time no signal or a very poor signal.
If i don't find a way to repair this problem, i think return with kit-kat.
Hi. Let me know if it works!
