RIL and modem problem! I9300 with Cyanogenmod 10.2 Stable! - Galaxy S III Q&A, Help & Troubleshooting

Hello there! I have a i9300 with CM 10.2. Works really nice! I also have TWRP. I looked everywhere for a compatible modem and RIL set because original set (that came with the phone and was modified by CM) doesn't show my signal strength corectly (it is a HUGE number). I'm looking for an unbranded, Europe modem. Also, thanks for reading my first post!

I think you are new to here.. would be better to read Faqs and Guides First to Know about your device and do rest of the things else you will mess up with it..

As far as I know, you should flash a modem without Ril because Cm have his own, or you will end up with a No Signal..

I have flashed ROMs on my Samsung Galaxy S since 1 year so I know some stuff. I never worked with modems and RILs. I knew CM has it' s own RIL but I thought maybe it would work with other RILs too. My modem is XXLF5. Also, the modem you have is umbraded? Because my phone isn't bought from Orange, it's unbranded by default.
By the way, thanks for giving me tips! Much appreciated!

I have flashed BUEMC2 modem(no Ril) with cm 10.2 and it's all OK for me even if the Ril don't match with the modem, but I'm from Italy with Vodafone carrier.. Here is a list of modem+Ril for the i9300 http://forum.xda-developers.com/showthread.php?t=2076857
if you want only the modem, delete the System folder that is in the zip file.

I'll look for a modem that suits my needs and post back the result! Thanks!
Edit: If I install a branded modem onto an unbranded device what will happen?
Edit 2: I installed BVELK1 branded to Orange (even if the phone is normally unbranded by default) and works fine! I'll keep testing and I'll decide if I keep this one or resume my search. Thanks a lot!

From what I've read, Modem are related to your SIM card carrier and country .. In fact my phone was branded Tim, but my modem is for Vodafone / Europe , matching my actual carrier and works very well..

Thanks, but I consider moving to another network, should I change my modem or is there a way to unlock it?

Hey
I had the same problem with the high dBm values after installing another modem/RIL
around 1200dBm for weak signal strength und ca. 1900dBm for good signal.
After reinstalling the RIL that came with CM10.2 everything worked fine (I made a Nandroid-backup)
The RIL is just the files in /system/lib/
libril.so
libsec-ril.so
right?
if yes => i could upload it (but I'm not shure if this will break any certificates)
