Or Continue to Thread: [Q] I9305 stuck with EDGE and …
Long time lurker, first time poster.

Long story short, a friend gave me an I9305, however, I can't connect to a supported 3G network.

He had toyed around with the device (rooted, installed CM11), then reverted unrooted and reverted to stock firmware. When I got the device, I rooted it with Framaroot, flashed CWM, then flashed CM11 and Boeffla kernel. My SIM card was quite old and my carrier told that it doesn't support 3G, so I filed up for a new one. Ok, I got it, however..I'm yet again stuck on EDGE!!!

Tried reflashing CM11, CWM, flashed almost every radio baseband modem from here to no avail. My IMEI is intact, as well as my Serial Number.

Yes, I read all threads, I tried going to Settings>Wireless&networks> More > Mobile Netwroks >Preffered Network type and checked all options. When I select 3G only, the icon goes to "H", but i can't access the web. After 10-20 seconds, the H icon dissappears and I'm forced to reboot the phone to regain my EDGE data.

At the moment, I'm running the latest Omni ROM nightly. My operator supports all 3G and LTE bands, and I got the correct APNs.

Should I flash a stock ROM and check if this does the job?

I'll greatly appreciate any help, because I'm stuck.
