[Q] Very Slow Mobile Network, Kinda Strange.
Hello everyone, first of all I should post this to Android Development section but since system tells me I do not have 10 posts, I thought I can post this here.
Well basically I was using Disaster ROM for my SGS2 (International) (I'm in Turkey), and I wanted to use Biftor Rom which was actually KitKat and I didn't know that I should install CM 10.2 or newer first to install other KitKat Roms. So I actually softbricked my phone I was only able to go into download mode. So I flashed my phone with stock 4.0.3 using Odin. But I realised that my mobile network was actually slow as hell. Sometime it can't even connect. But I was like "Oh anyways, it will go away if I flash custom rom". But it didn't. I checked my IMEI and it was there, valid. I flashed my phone 4 or 5 times more with different ROMs. But no luck.
Then I heard an app called GetRIL, because someone told me that my baseband/modem thing might be corrupted. When I opened the app I saw that it says "Unknown RIL". So what should I do? I tried setting APN manually, then automatically by my Vodafone Service. Nothing happened, still same. I do NOT want to send this phone to Samsung Service, what should I do about this situation?
Some Details : My WiFi works very well, I can call other phones, I can send messages, I can recieve calls and messages, Only thing is Mobile Data So Slow and sometimes when I turned data on it says no signal for a while. Help Please !
EDIT: Stock 4.0.3 was only PDA file. It wasn't like 3-4 files to set into Phone section, Pit section... It was only PDA. At the moment I am using BeantStalk Rom 4.4.2 KitKat XXLPS Baseband.
Thanks in advance.
