Lost connection. - Galaxy S II Q&A, Help & Troubleshooting

Hey there!
First of i want to tell you that i don't know if this is the right section to post this in otherwise tell me please.
Okay so i am having a big problem with my connection, it drops at random and never reconnects till i reboot my device. I am having this problem since i changed my kernel and my rom to sensation rom. I had another kernel and lite 'ning rom before. Now im wondering what could be causing the connection loss. The kernel or the rom or could it be both?
I hope someone can help me with this cause it is rather annoying not recieving important calls.
Peace

Not if you read the rules .
Question = Q&A which is logical .
Stock rom and test is the only way .

is there no one what could be the problem of this?

What model is you phone (international, T, G etc)? I have an I9100t which has a different modem to the international version. When I flash a new rom I reflash a T version modem.

Hello
My friend had that as well on the stock rom. Found out it was the sim card.

[Q] Cannot hear phone calls after flashing custom rom

After flashing a custom rom, I lost the ability to hear anything on the phone when calling out or being called. This was my first time flashing a custom rom so maybe i missed something during the process. I did a factory reset but still no sound while making and receiving calls. Please help me resolve this issue.
You most likely flashed a rom from the GT-I9000 international Galaxy S2- You need to use odin to flash stock firmware and modem, the thread can be found in the development section.

you might want to reflash the right modem. You can find it in the development section
That worked like a charm. Thanks.

Next time, make sure to flash ROMs intended for the I777.
ROMs intended for the I9100 will have the following issues:
1) Telephone functions flaky if working at all
2) Bottom buttons nonfunctional
Absolutely. Being a newbie to android, this was a lesson well learnt.

Phone not recieving text messages

Hi, at least a couple of times a day my phone will not receive text messages that friends have sent me, or they will come through an hour late, could this be a problem with flashing custom ROMs? Or will it be my network. does anyone know a fix for this if custom roms are the problem? Any help is much appreciated. Thankyou

well the first thing i would do in this situation is to check the network issue by putting the same on a diff phone may be a non -android one and see.
if issue persists then its network / sim card for sure the culprit.
if not the case, then i would post this issue on the custom rom ( the one being used on phone) thread so that may be some one have a solution for it there.
It happens on every custom ROM I flash, I change my ROM around once a week. But before I started flashing ROMs I never had this problem. Does the modem affect any of this? Thanks.

Modems are cross compatible. GB modems work on ICS, and ICS modems work on GB.
Just modems though. Don't try with kernels or anything else.
I've had this problem before and it was my modem, not the ROM.
Flash a different modem, and it'll fix it.
thanks guys what modem did u try that fixed it? ive tried XXKI4 and XXKH3 and still have the same problem

Go to your Applications, and click on "Messaging" (or something like that), clear the data. Then flash any modem, wiping cache and dalvik cache before you reboot.

Go to www.sammobile.com and download the firmware and flash through Odin. Do not use repartition or pit files

Some questions regarding root...

Hi all, (this is my first thread)
I wanted to ask a couple of questions about which I am confused...
I am currently running stock 4.1.1 on rooted international galaxy s3..
Q1. Is there anyway I can get 4.1.2 OTA Without unrooting?
Q2. I am not sure whether the country I bought my phone from has got the update yet... So is there anyway I can check that...
P.S I got my phone from dubai..
But I live in India...
Thanks.

If you already have CWM recovery why not use CWM to flash a custom 4.1.2 rom thats based on Stock firmware (like Android Revolution HD)?
Thats just as easy, has more support, rooted and you'll have future updates faster as well.
I already downloaded omega v34 but didn't flash it because people have lot of issues with it.. Lag, random reboot etc. Stock rom will be more stable I guess..
I haven't tried revolution though...
I'll try it now..
Any other rom you recommend?
Thanks!

I had the same experience, Omega had loads of launcher redraws and sudden lag. No such experience on ARHD with Perseus kernel. That kernel now even has the exynos exploit fixed.
Nope, all other roms i've tried i never used more then a few hours.
Can you give me a link to the ARHD page?

Yeah, everytime you flash the stock image, you'll have to root the phone again... but so what?? I have my mobile sine 8 weeks and i think i flashed it 10times now, and lots of custom-rom installations, configuring the phone etc....
It's not a hard work, you just have to read carefully BEFORE you start rooting, modding or whatever. This forum is awesome and till now i really found an answer to my questions everytime without bothering the ither guys with a question that is already answered a thousand times just have to use the search... so, good luck and have fun with your rooted mobile. By the way, i recommend the Omega-ROM for galaxy S2 and S3, the guys are.doing a great job with their ROMs. If you own a S3 LTE (i9305) i recommend the Pandoriam ROM, works best for me
Best regards

Haha.. Thanks buddy.
Btw, I am not new to rooting, I have flashed at least 15 rom's on my old phone(galaxy ace)
But I was not a member of XDA then.. I just used to read....
But since s3 is much more expensive I wanted to be absolutely clear about the smallest of things...
Because with great power comes great responsibility.

RIL and modem problem! I9300 with Cyanogenmod 10.2 Stable!

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!

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..

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)
