[Q] Galaxy S2 Modem - Galaxy S II Q&A, Help & Troubleshooting

Hi.
Im having a little problem here.
If I want to flash a modem, do I have to find the same modem version as my firmware version?
As in, if my firmware version is XXKL3, do I have to find a modem which is XXKL3 so that they will be compatible or something.
Help will be greatly appreciated! Cheers!

As far as I'm aware, you can flash any sgs2 modem you like. Mine doesn't match my firmware.
Edit: in fact, there's a list of flashable modems thread around somewhere.

Can modems be flashed on any kind of kernels? CF-Root, CM7 ?
Are modems made for different regions and carriers? For example I'm in Czech Republic on O2 ? What should be best ?

Yes. Modems are independent of kernel or rom.
Some modems do tend to work best with different carriers/networks, there are two ways you can find a modem that works well with your carrier/its network:-
1) Flash a bunch of modems until you find one that works well
2) Do a Google search & append XDA to your search terms; for example, SGS2 XDA modem Czech Republic. Use your imagination with the search terms.
Having said that, if the modem you're currently using gives you good connectivity/data speeds with the rom/kernel you're using at all locations/at all times of day (to rule out any problems that could possibly be caused by congestion on your carrier's network, etc), there's no need to go changing modems.
You only need to do so if you're having those consistent problems I mentioned.

Hi,
Will ask here:
What are currently most up to date and best modems? Ok I know there is no best modem but what are current modems that are giving best results for most users and otherwise behaving good in mean of performance and battery life?
Now I have xxkl1. Any better?

donno when last updated this thread, but lot of discussions are there :

Modem / Radio Thread ?

Hey folks,
wouldn't it make sense to create a seperate Modem / Radio thread for the S2? Since more and more official roms keep popping up, and we also have at least 3 different modems floating around I think it would be great to have a seperate thread with download links for the modems and also a place to discuss them.

What's the best radio for a Chilean SGSII for use in USA on AT&T? The current stock version is finicky with 3G speeds...kinda like the I9020A Nexus S Canadian version requires a radio flash to work on fast 3G on AT&T...

Start at kg6 and work downwards fill you find one that works for you, as modems are very region and carrier specific

Samsung Galaxy S2 - GT-I9100 and GT-I9100T what's difference between the two?

Hey guys I am living in thailand I own a official unlocked Galaxy S2
but my model no. is different from global variant it is GT-I9100T instead of GT-I9100 , do you guys have any idea about my handset ? Is it lower on specs or it doesn't have NFC or USB OTG ? I have no idea about this. Thanks in advance

GT-I9100 = International unlocked
GT-I9100T = AT&T model
and this topic is in the wrong section
How can it be the AT&T model when I'm using it here in Israel?
They are also used in Australia by Telstra and Vodafone. Only difference is that they need different modems to get reception. You can flash a i9100 stock or custom rom on the T version but will then need to flash a T compatible modem over it.

So just different bands on the GSM spectrum? I flashed CM7 onto my phone before and everything seemed to work.. still I preferred the stock ROM and flashed back. Today I got a text from Cellcom saying there's a new version of firmware out.. so I tried OTA update and got the no new versions message. I also tried Kies and it said "it is not possible to upgrade the firmware on this phone" or something like that. I already have 2.3.5 though...

I'm also in Bangkok and i got i9100T. The difference is the 3G connection of your Carrier. If you are on AIS, you get wrong one. i9100T will not work 3G on AIS and it will work only on DTAC and TRUE as they have different version of 3G signal. If you are not using 3G connection then you have no problem using i9100T else you need to switch to DTAC or TRUE. When I buy my Phone, the Vendor asked me which Carrier I will be using and I asked for AIS. However, they gave me wrong one i9100T and now i have problem with 3G on AIS. It does not work any internet connection when I am at 3G area. My Vendor promise to change on next week. At least I learn what is difference as they gave me wrong model else I may not analyze the difference. Hope this help you too.

Its the same. The only difference is the Model which controls the baseband you use. Just root and flash the international modem so its mostly compatible with all networks.

AT&T's Galaxy S2 is not GT-I9100 or any variants. Its SGH-I777.
GT-I9100T are sold in Every part of the world except the Europe and North/South America. Theres no difference at all from the international version.

Is the hardware on I9100T different than I9100 as far as supported 3G bands ?
If I need 3G bands 850 + 2100 which model should I look for ?

All bands are enabled.
Contrary to NZed;
There is a slight difference between the 9100 and 9100T. Not in hardware, but software. The specific T modems are generally more tuned to the 850MHz band than others due to different SAR levels.

Please read posts 8 and 12 again.
Or read this thread, which goes into some depth about what the differences (negligible) are. You can flash an I9100 ROM to your I9100T phone, but you will probably need to flash I9100T modems afterwards to get decent signal.
Hi everyone, first post here but I assure you I have been searching and searching through this site for some time with no real luck so I decided to post in this thread rather than start a new one as it is closely related.
I too have the i9100T and I can assure you it is not specific to Australia. This model is available all over Asia. I am in Thailand.
I was rooted before and experimented with a few ROMs but decided to just skip the hassle of all the bugs and weird problems by reverting to the stock kernal. It works best for me. However I appreciate being rooted and would like to root on ICS 4.0.3
I am currently on the DCLP5 kernal and I can not seem to find that specific corresponding CF-Root kernal over here : http://forum.xda-developers.com/showthread.php?t=1103399
If I am right and there is no CF-Root DCLP5 kernal which kernal is the closest that I may use?
Sorry if it seems like I am thread hijacking.
I have been searching for awhile and can't find the answer myself. I'd rather not start a new topic as the answer could possibly be there and I overlooked it.
If anyone can inform me of which is the closest kernal i can use to gain root I would greatly appreciate it!
Please and thank you!

I can't find CF-Root for LP5, so you're probably right. You can try SiyahKernel, but I don't have an I9100T so I don't know if that's safe.
Your best bet is to flash an ICS custom ROM from the I9100 section (there's loads) then flash the right modem.
Or better yet - use AOKP (Jelly Bean).

Hmm, I see. Well, nevertheless, I thank you very much for your help.
Are there other methods of achieving root?
For example, In my desperate attempts I came upon this method... ( galaxys2root.com/galaxy-s2-root/how-to-root-galaxy-s2-newworks-on-all-galaxy-s2-variants/ ) ... but it only works on early gingerbread versions. (Kind of misleading IMHO)
I just need root, I don't mind which method as long as I get the final result.
Again, thanks for any help and advice.

[Q] Galaxy S 2 Signals Problem

My galaxy S2 is dropping network signals. Where my S1 shows 4 signal-bars, S2 shows 1 or 0 bars for the same network. But when I start using my phone, it goes till 3 or even 4 bars. In sleep mode it doesn't catch any signals. That mean I cannot receive any calls/sms when my phone is locked.
When I take out my phone and unlock and start using it, it suddenly get a few signals and starts receiving pending sms.
I heard somewhere it could be a problem with my custom ROM. So, I've upgraded to Stock ROM version 4.0.4. But the problem is still there. Can anyone please help me fix this issue?
Thanks

Sorry for having very basic knowledge of Android. By changing kernel do you mean to try flashing some other ROM?
Previously I downloaded the ROM from: http://www.sammobile.com/firmware/?page=3&model=GT-I9100&pcode=OXA&os=1&type=1#firmware (I downloaded CSC: I9100OXALQB)
If you mean to change the ROM, can you please suggest me any other ROM?

The forum is useful. People helping you out aren't doing it for any commercial gain. They look around in their free time and help you solving your problems.
He said you may need to change your modem. Not your ROM. The best modem for you generally depends on your region. So search this forum for a thread detailing the modems for various regions, download the relevant one and flash it.

I did that comment because I've posted two problems and got no response. It seems no one looks at the questions at all.
I am not sure what you mean by modem. I bought this phone from KSA and I flashed a Poland ROM into it.
Do you think that would have changed the modem?
Yes it would have changed the modem. There is a modem thread here on XDA, find it and use Odin to flash them.

Just flash the modem no need to install an entire rom just for signal issue as far as "suit my phone" u have to try different roms for that i suggest you should read a few threads on the site
I tried flashing Poland, UAE and PAK ROMs. But nothing worked. I still have the worst signal strength

whats the best modem?

im using gt-i9300
with UK(unlocked) version of stock 4.1.2
and currently leaving in Australia Sydney under Telstra.
what would be the best modem for me to flash my phone with?
atm I have a really old modem which was from ICS days.
also isit true with different modem you could actually save more battery than usual?

the best modem is the one that works best in your region with your provider
I guess you will be able to find some recommendations in the modem collection thread as it lists all modems for all regions, hence try them and see
edit: here you go
in addition, next time please post on correct thread or section (Q&A)
You will eventually come across the best modem after you've tried every modem there is and then asking yourself which one worked best for you. FOR. YOU.

Install Perka's file stash from play store open it and select galaxy s3 select modem then modem cwm then download na8 (recommended) or anything you want. Then just flash it via recovery.
I also search a lot of but couldn't find anything then I find this app which is awesome even I unlock my phone by flashing modem from this app. Flash it and let me know.
