Hi,
I have an issue with the radio of my phone. When I switch to 3G, I get a weak signal varying between one and a max of 3 bars. The phone gets heated up and the battery starts draining. Please find below the device and OS that I am using
Device: Samsung Galaxy S2
OS: CM M12
Base band: I9100DDLP8
Location: Bangalore, India
I have inserted my Sim in a different phone and have found that nothing is wrong with the connectivity in the area. I have no issues when I switch to 2G. I have tried flashing various modems and RILs but in vain. I have also tried using the Getril app to correct the issue but without much success.
Here is what I have tried and noticed
1) Flashed the modem DDLS9 and DDLPB. The 3G signal strength is good when I flashed these modems but I am unable to make or receive calls. I have flashed the RIL along with the modem.
2) On trying the modems XXLS6, XXLS8, XXLS9 and XXKH3, nothing has changed and I still got the weak 3G signal though am able to make and receive calls.
I have also tried flashing a stock rom (Jelly bean) but the issue was still there.
Any help is much appreciated. Thanks in advance
As you have tried all the radios for the location already, I am not going to suggest you to do that.
However, I am interested in knowing when did the phone start showing signs of weak 3g signal? Did it happen one day suddenly or did you make any changes to software/hardware which might have triggered it?

It started happening after I switched to Cyanogenmod 11 M1. I was under an impression that the issue is with the connectivity until I tried my sim card on a different phone.
I will suggest you to flash the stock ROM or some other ROM.

Tried installing the stock rom but it didn't work.
Number one thing I also say about modems and rils, never use getril. Are you trying to flash jelly bean stock rom? If you haven't yet, try flashing it as it will also flash the stock modem too. If yes, try finding older versions of the compatible baseband firmware (or modem) and try flashing it. (Yes, you can flash older modems that originated from ics or jellybean).

Hi! This is my device
Device: Samsung Galaxy S2 gti9100
ROM: CM10.1 nightly 20130610
Android Version: 4.2.2
So I was having some trouble with my 3G, I was only getting 2G. So I decidded to flash a new baseband, which I found on here: http://d-h.st/users/ApriliaM3/?fld_id=7487#files
With this, I successfully got my 3G on, also 2G. But the problem now is that I can't make any calls!
No sure if its a baseband problem since I have 2G and 3G from carrier. Can anyone help me?
Thanks!
You haven't told us which modem you flashed (Tho it doesn't matter that much given you're going to have to change it anyway).
OK. You need to be methodical to fix this. So...
1) Start with stock roms released by your carrier. Find out which modems were bundled with those stock roms, and flash/test those first. Rationale behind this is you'd hope your carrier would have fully tested their stock roms before they release them including the modem, to ensure that the modem works with their network most of the time & in most places.
Still having problems ?
2) Stock roms released by other carriers in your country. Find out which modems were bundled with those stock roms. Flash/test those.
Still having problems ?
3) Flash/test every other modem bundled with every stock rom released by every carrier who sold the I9100 you can get your hands on (there are dozens).
And now that I think of it, if it were me in this situation & the problems persist after trying 1 (the modems bundled with your carrier's stock roms), I'd probably do a clean install of the rom I was using including a wipe/nuke in case there's something funky rom-side causing it.
If you're still having problems having done all that, you might want to do a clean install of stock & start with modems bundled with stock roms released by your carrier to rule in/out a CM problem.
And if it's still happening with a clean install of stock & using the modems bundled with your carrier's roms (which every 'ordinary' user who uses the SGS2 with your carrier & is running stock and doesn't mod their phone uses & has no connectivity issues most likely), it's either a carrier-side issue or a hardware problem.
What happend was you flashed modem/ril. Dont flash ril on custom rom. Bye bye imei. Have a look. Settings,about device, , status look for imei see of its blank.
Hello everyone
I have a SGS II GT-i9100T which is a gift from my brother from New Zealand.
I´m running CM 10.1.3 and sometimes my signal drops, "Emergency calls only"! I´ve tested the Simcard on other phone and it´s fine.Could anyone suggest me a modem to flash to my phone?
I´m living in Germany and using O2-de.
Thank you.
Here is some info in case you need them:
i am not very sure whether geographical location affects modem or not, but there was a country based thread for India. They have some popular modems listed out here -
http://forum.xda-developers.com/galaxy-s2/general/i9100-modem-reviews-india-user-based-t2184193
You can get flashable modems here - http://veyka.co.uk/sgs2/radios/
have fun testing them.
Forget the fact you're in Germany; stick to modems bundled with stock roms released by carriers who sold the I9100T. Go to Samfirmware, use the pulldown boxes to make a list of all the stock roms released by carriers which sold the I9100T (there aren't many). If you click through each stock rom in turn it will list the modem - make a list of all the modems. Then search for CWM flashable versions of these modems on here (easily found with a search), download them, and start testing them out.
Only if you get to the point where you've tried all of these modems & they don't improve your connectivity should you consider flashing regular I9100 modems (I know this because I have an I9100T).
You might also be suffering from a long standing problem with CM roms where connectivity just goes away for no particular reason at all. The way you'd test if this is the case or not is to do a clean install of a stock rom released by a carrier which sold the I9100T (doesn't matter which, but don't flash 4.0.4).
I missed on seeing that the phone involved here is i9100T. My Bad.
Apologies for feeding you wrong info here.
sorry for "ruining" this thread, but:
1. How to know what the best modem is for you (I live in the netherlands).
2. Can you flash a modem on any android version? (I'm on carbon 4.4.2 rom).
3. Is it safe like rom flashing?
^^^
1) The way I always tell people to approach this is similar to what I said to the OP; go to Samfirmware, find all the stock roms released by your carrier, click through on each one & make a note of the modem. Search here/Google for CWM flashable versions of each modem, and test them out. If you find you go through all the ones bundled with stock roms released by your carrier & your connectivity is still bad, do the same with modems bundled with stock roms released by other carriers in your country. If your connectivity is still bad after that, flash any modem you can get your hands on.
But for most people, modems bundled with stock roms released by their carrier should work best; rationale being you'd hope the carrier would have fully tested them to ensure they work for most people most of the time on their network.
If your connectivity is currently fine, there's no need to go messing around with modems. Chances are you'll make it bad if you do I.E if it ain't broke don't fix it. Only mess around with modems if you have problems with connectivity.
2) Yes, modems are independent of Android version.Same risk as flashing anything else (I.E very small risk of the flash going bad with any given flash).
3) Risk should be minimal; I've never heard of anyone borking a phone with a modem misflash, but anything is possible I guess.
Hi.
This morning I realized that I had no data connection in my SGS2. No E, no 3G, no H, no H+. Unable to connect to the internet. WiFi works seamlessly.
I was using SlimKat (http://forum.xda-developers.com/galaxy-s2/orig-development/rom-slimkat-i9100-t2552988) and no significant changes were made yesterday.
Inmediately I thought that I had no data available in my prepaid card. I checked with my provider (Lycamobile NL) and there were connections till 20:00 aprox, when I got home and hooked to the wifi. Nothing in the mornig. Data available in my account. I have tried the SIM in a different phone and works perfectly. I can make and receive phone calls, as send and receive SMS messages.
Thinking that it could be a problem with the rom I've installed PacMan (same result) and currently have installed last NeatROM. Same result.
I've also traveled to France, where I'm now: with a Lebara FR SIM that I've just toped-up I get the same annoying result: no data.
Data connections are enabled under Settings --> More... --> Mobile network settings, as it's also enabled the National data roaming. APNs are correctly configured and selected.
No software was installed neither settings changed neither in PacMan nor NeatROM.
A mistery.... any clue?
Clean install of stock to test in the first instance, then a clean install of the rom you were using. Could be the 'connectivity just goes away for no particular reason at all' thing I used to see on AOSP roms all the time when I ran them on my S2 (and was the reason I stopped using them).
You could also try flashing modems; starting with modems bundled with stock roms released by the carrier you're currently using.
It could still also quite easily be a carrier-side issue despite what you've said/checked. Everyone (on here) always thinks it's a phone-side issue when connectivity is poor/changes/non-existent, 80% of the time it's carrier-side.
Thanks four the advice MistahBungle. I'll try with stock.
On the other hand, the carrier issue is discarded:
- same SIM works in a different phone, in sake physical location.
- a different SIM, different carrier, different country, shoes the same behavior in the phone
Sends to me that that's a phone thing...

Yep more than likely something phone-side with that extra info you've provided. Try those suggestions & see how you go.
In my case it was waterlogged mainboard issue. I don't think that's the case with you but still, even after trying all the above you still face the same then the antenna module would be worth checking.
Praying for your s2's soul and your pockets
Restoring Stock firmware (I9100XWMS3_I9100FOPLS6_FOP) didn't help. ((
Now I'm completely lost... (((
Try flashing some modems for your area/device.

That's because you didn't read my post. I did suggest two other things, which Banjara helpfully/unnecessarily repeated.
If you want this issue resolved, it's going to take some effort on your part.
Just installed PacMan stable release (milestone 1).
Apart from the same behavior with the data connection, the browser does not launch.
Installing Resurection Remix right now. Let's see.
Just installed Resurrection Remix and same behavior.
Trying to find AOSP KK modems now, if possible from Netherlands network providers, ideally from KPN.
I have a question:
If I have flashed a AOSP rom (i.e. Resurrection Remix) which is KitKat, can I flash a stock modem wich is Jelly Bean?
I'm asking so because you adviced me to flash modems bundled in stock roms (which for I9100 stop at 4.1.2) on a AOSP rom (which is 4.4.2 kitkat)
Thank you for your support.

AFAIK,Modem is not dependent of the android version for u so u can flash the modem .
Yes u can downgrade from 4.4.2 to 4.1.2 (but perform all the necessary wipes before doing the downgrade)
it worked!!!
Flashing modem.bin from the stock 4.1.2 on the Resurection Remix worked )))
Thanks MistahBungle and the others for the support!!!
Let's see now if it works also with NeatROM!!
Thanks again!!!
FYI, NeatROM worked as well!!!

hi guys,
I purchased a used s3 from eBay that was unlocked to all cariers but was originally on Orange network.
I rooted it and flashed ultimarom 16, which is great. but my signal is awful.
I am on three UK network and maybe I need to flash a different modem?
please help =(
help
I've tried same rom with similar problems in my s3.. changing modem will help, but I completely solve the problem by changing rom... I'm tring the SlimKat, and I never seen my s3 working so fast... don't have to charge it everyday and the signal is so much better than ultimaRom for me

what network are you on if I may ask?
I did try slim kat. no noticeable improvement.
can anyone tell me where I can find a modem that I can flash from recovery

I live in Italy and my provider is "TIM". I'm still with SlimRom and enjoyng it.
You can easily flash modem .zip files from recovery if I remember well, just take a look on google for i9300 baseband/modem "yourprovider", and you will get some of them..
Hi,
I have some problems with modems and signal strength... I have search other threads but did not find anything really useful.
I bought an i777 when I was living in America for work, but now I'm back to Italy and I see that I always have bad signal (I've checked also with Better Battery Stats). I've tried different modems, but didn't see remarkable differences...
When other people asked for this stuff, the answer was almost always "install and try". Do you know if there is another way to test modems?
Since the i777 is from an American carrier, is it possible to port an i9100 modem?
Thank you!

Short answer is no, i9100 modems will not work on an i777. While the devices are alike in many ways, modems from the i9100 aren't compatible (or portable) to the US variant. You can flash an i9100 modem and the phone will boot up fine, but you'll run into trouble with not being able to hear the caller/them hearing you. Normally this workaround would be to flash an i777 kernel with MicSwap capabilities, but that will have no affect on a modem as the baseband's are different.
Perhaps a longer answer than you needed. Sorry, I'm not aware of a real solution for you other than purchasing a different device for your region.

Thank you for the answer SteveMurhpy! I can't change phone right now, so I'll have to try the other modems... do you know if there is a faster/better method to test them than to install and try? And how much does the version of the OS interact with the modem? I am on Slimsaber right now... Thanks!

I don't think the OS has anything to do with the signal strength, if it did it would likely be on older firmware such as GB, ICS and not the KK version you're currently running. As for the modem, unfortunately there's no way to test signal strength prior to flashing, so you're just going to have to keep trying them until you find one that works in your country.
One might suggest alternate APN settings, but that has more to do with functionality and speed rather than signal strength.
Sorry, as far as I'm aware there's no easy fix for you.

I had some doubts about the compatibility between modem and OS because when I was back on SlimBean and I flashed a modem from GB the System UI kept crashing... but maybe there other types of problems, I didn't investigate that much.
Ok then, I'll keep trying... maybe I'll find the right modem for my country!
Thank you very much again SteveMurphy!
