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.

I'll post it then.
Can I make a noobie question?
What are the modems?
I found this thread: http://forum.xda-developers.com/showthread.php?t=1131950
And I don't understand what is it for.
Thanks!
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

I'm pretty sure that it will be new.
I got a question about flashing a modem on my phone.
was bought in India but now i live in Israel.
I'm not sure if I'm suppose to flash the KF2 Modem or another one?
its suppose to change the whole battery situation if you have the right one, right?
anyone had to face with this? Does it actually have a difference?
Also what if i flash my phone with the KF2 while the phone is suppose to have another firm?will it be a battery\reception problem?

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.
Try to use method 1 from 1st guide in my signature.

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 :

I just received an S3 ordered via an established eBay seller.
However, the seller neglected to state that the S3 is Polish - instructions and some box text is in Polish.
Is this ok or am I likely to experience any oddities? Do I have the correct firmware that I want/need for regular UK use?
As yet unopened.

And that is easily fixed by flashing the latest UK ROM (doesn't increase counter) and changing the CSC code to your region (BTU), App on the appstore and requires no root.
So basically yeah it will work 100%.
I was on the verge of keeping this phone, but I just bought a new Three UK monthly rolling sim today and I am getting download speeds of around 100Kbps and poor vice call quality. I don't know whether that is just Three but the data is way too slow. Could this be because of the modem software on board?

Skander, could you point me to those things please? Would changing the CSC do anything to help me? Whilst that may not reque root, I guess flashing a UK rom would, right?

You flash them with odin. Make sure to get 4.1.1 modems if you have updated to JB. The csc includes things like apps from three, and won't effect your download speeds.
I would recommend watching the youtube video on this thread:

Ugh, confusing. So, grab the 4.1.1 package download and flash that? Thigh the thread doesn't say, it should contain some Three stuff?
I'm on the verge of just returning the Polish phone and having the seller mail a UK handset or refund entirely rather than messing rand.
Thanks for the tips.

Have you noticed the "Roll up sticky thread" in the general forum? The noob friendly flashing guide is a great place to start.
The csc is not needed at all, and most would be happier without it.
There is no hardware difference between a polish and british handset. A few hours to get used to flashing and you can get a fine working S3. This includes JB, ICS, polish csc, british csc, modems etc exactly to your tastes.
I had rooted and flashed before with my S and S2, but kinda wanted to start my S3 life in its virgin state.
Though I had been attributing the horribly poor call quality on my S2 to my network this year, it may even be down to whatever I've flashed on to it.
