I was using the S2 with Jelly Bean. I found the phone to heat up very quickly around the camera lens and top of the phone rather than when running on Ginger Bread. I then installed the Resurrection Remix Custom ROM v5.1.3 with KitKat 4.4.2.
But the heating problem is still there. Checking online I found out that the modem was the problem.I found the KH3 modem was the best for the Galaxy S2. I was wondering if installing the KH3 modem was appropriate on Custom ROM or can modems be installed only on Custom ROM???
If it can be installed can anyone guide me how ... BTW I am using the phone in India ...
Please reply the overheating problem is driving me nuts.
Attatched is a screenshot showing my phone information.
You question is a bit confused (because you haven't taken the time to learn 'the basics' like 95% of people who come here), but the answer is yes. Modems are interchangeable between Android versions on the S2 & not dependent on same; I.E you can flash a modem that was bundled with stock rom that was a different Android version to the one you're currently running (whether stock or custom, makes no difference).
As to how to flash a modem....C'mon....
This is absolute basics, you should know this stuff back to front inside out if you're flashing custom roms.
In other words, search.

I know how to flash the modem using Odin ... I was just wondering if I can flash it on any Android version or any Custom or Stock ROM... and just to be sure the modem zipped file is about 4.5mb right?? Coz I found a KH3 modem file on one blog which was about 200MB in size ...

Usually a modem file size should not exceed 10 MB. You can even flash the modem via cwm. On xda you can find links for such files.

That's not required. Just keep a flashable file of your current modem, just in case you want to revert. I mean, download it and keep it on your phone.
For India, ddls9 also works quite well. I have seen good results on xxls8 too.

If something happens and I restore the phone from a backup of the phone , will the firmware baseband be restored or thats something else??
Firmwares are included in the backup or not??

I am not very sure about that. My guess is that it doesn't backup your modem with the rom backup.

Guys,
Recently ditched my Desire HD which I've had alot of fun with for (what I considered to be) a far superior phone but basically got a little fed up with the display after catching a glimps of the SGS2's screen, haven't had the HD on since!
Although I considered myself adapt at flashing and rooting, I have to admit to finding myself a little confused here as to what exactly I can do with my phone. Yep, I've searched, nope, I don't want flamed, just need a few things cleared up then I'm off to have some fun!
Details from my phone...
PDA: I9100XWKF3
PHONE: I9100XXKH3
CSC: I9100CPWKD1
I'm rooted using CF matched Kernel and have remained on that, does no harm as far as i'm aware except for yellow triangle at boot..
I'd like to go from 2.3.3 to 2.3.4 too and wondering about what to flash and what would fit, my CSC is Carphone Warehouse would that be correct? How important is it to match CSC?
Regards Baseband, doesn't really matter does it but no harm in trying modems is there?
And firmware, thought about Frankenstein XXKF3 or 4 or am I getting things totally wrong? Think it's the WK to XX and not sure what impact that'll have.
And on that note, does the firmware version stiplulate which ROM I can load? So if i go to 2.3.4 (XXKH3 or 4) am I then limited to flashing only XXKH3 or 4 ROM's? Does it matter what I flash over my phone? I've also read that some ROM's contain Kernels and may have to flash a stock kernel after flashing the ROM to match firmware or even re-root?
Actually the more I read back on that, appears I know nothing at all and that's not even funny! Even went back to the original SGS forums in the hope that I'd find what I need there.
I know that unless I move back to stock (which I am at the moment), Kies wont off the eventual 2.3.4 update but to be honest I'm not fussed as developers and cooks here do a much better job and that's experience from my HD days.
I have flashed MIUI as that's the ROM I used longest on the HD, loved it but quickly went back the more I satrted to read and to be honest, would prefer to stay stock for a while and get used to the phone, is that do-able with a flash from the developers forum?
So does the ROM have to match the firmware I'm currently using, can I upgrade to 2.3.4 firmware, choose a kernel of my choice and any rom?
Obviously not picking something up, hopefully someone has the answer I need without the links to pages read allready, want to start having some fun and soon!
Cheers!

firmware is read by the last three letters KF3 is what you currently have.
there is no problem upgrading to KH4.

no your not limited to flashing any rom, you can mix and match arounding to your needs and preferences.
after rooting they reflash the kernal to get rid of the yellow triangle, there is a tuturial for that chainfire's rooting thread, 2nd post.

no the rom does not match the firmware, yes you can upgrade to 2.3.4.
yes you choose the kernal and rom that you prefer.
All roms contain a kernel .
CSC is not really required as long as you enter the settings for your network manually but stick to cwm or xeu for UK ..
CSC are not upgraded and are often much older than the rom version .
KH3 probably the best current modem .
Rom is the whole firmware kernel modem OS etc .
You can have a KF2 firmware and swap kernel to KH2 and modem to KG2 in theory and it will work most of the time for varying combinations .
USB jif is better than flashing kernel to remove warning triangle as it also resets rom counter to zero
Me >>Cognition 1.51 rom based on KH3 and i have KG2 modem and no CSC .
Kernels have swapped just the kernel about four times on this and swapped and tried every rom on here .
Rom backed up using Nandroid via CWM recovery and apps backed up using Titanium pro .
Even a failed boot is usually recoverable with ease on SGS2 .

Hi,
I want to install cognition s2 rom on my galaxy s2 but first I wanted to know how can I go back to the stock rom if I happen to dislike the custom rom? I searched but couldn't find a concrete answer.
Thanks
Standard Method is flash a stock rom .
Reset custom rom counter to zero with usb recovery jig .
Stock Roms .and csc

Ok so maybe you can explain to me what's the difference between a rom and a kernel/firmware? Because I only see kernels on the page you sent me =)
Also, does it matter which phone/modem, csc I flash? If so how does it affects my phone?

a kernel is what directly interacts with the hardware. Every OS has this, but it's more customizable on our phones since it's based on Linux. The Rom contains the OS itself, and the software and file structure therein. The kernel even can tell the OS how fast the processor goes and how much juice to use from the battery.
from the link that JJEgan gave you, u just pick the one you want and flash with odin...thats all you need to do

A kernel is not the firmware
so flash as instructed with whatever 2.3.5 upgrade you are using .

if you want 2.3.5 then you have to flash the whole package, just download one of the files from that site and flash in odin under the PDA bit
So I just got a galaxy s2 unlocked. International. Was wonder what I need the flash or try custom rom?
Sorta confused with all this talk of modem version... help

I suggest you run CheckROM RevoHD v6 with the latest Siyah Gingerbread kernel. It gives me the best battery life when I implement MagicConfig.
1. Download CheckROM and Siyah kernel and copy it to your phone. Make sure you remember the location thereof.
2. Download and install the latest GB insecure kernel by Chainfire and install it via ODIN from your PC.
3. Enter recovery mode on your phone and install the downloaded firmware which is in a ZIP file
4. Reboot your phone and let it continue to complete the initial setup.
5. Reboot to recovery mode again, install siyah kernel (also a ZIP file) and reboot again.
6. Look for the MagicConfig thread and modify the kernel settings to get the best balance between performance and battery life.
PS: doing the above will void your warranty so be careful. I also suggest that you do a little research before attempting anything drastic. First read then ask.

Well I am asking about most how does modems have to do with the roms. I'm used to HTC with default radio and every rom works lol
Any Gingerbread or ICS Modem can be used with any rom period. It is just a radio and some perform better in certain regions. ( For me KL1 in Canada)

Well, any GB or ICS modem meant for your device, anyways.
Then why is there specific firmware for each modem? How would I backup all my original stuff?

We usually start by reading the Guides specifically Nandroid backup via Clockwork Mod recovery .An apps backup via Titanium Pro app .
THERE IS NO SPECIFIC FIRMWARE FOR EACH MODEM .
Firmware is released with a modem inside . Modem updates do not happen as often as firmware is upgraded . Apart from a few network specific locations all modems work with all firmware . Some users may find xxx modem better than yy modem .
Firmware is flashed as one file containing firmware /OS Kernel/ Modem/CSC in most cases all parts of the firmware are interchangeable within the same Android version .

Pretty simple question here. I searched the forums before starting this thread, but I got contradicting results...
I have Stock Samsung ICS 4.0.4 XWLPW on my GT-I9100. It has the default modem for my country, but I want to flash KH3 modem on it for better reception and battery life. Is it possible? (I didn't wanna try as last time I lost my CSC when I was flashing another modem and then did nandroid restore... )
I hope to get a reply.
Thanks!

u can as long as u get a tar file (or the Modem.bin file of KH3) of the same to flash vide ODIN, if ur Stock 4.0.4 is not rooted.
If rooted with a wrk'ng CWM then u can flash the Zip version which is easily available
Hey,
Just flash trough Odin(If tar) or CWM(if zip) And nothight bad will happen..
Just do NANDRIOD BACKUP
I flashed modem many times and and nothing happened..

What model number are the phones I9300 / I9305?
they are i9300t
I managed to root both of them. I know have a major problem. 1 of them had a problem with wifi. It couldnt connect. I read about a solution by copying the wifi folder from version 4.1.1. Tried that. It worked for once but after reboot it stopped. And now I can't even turn on the wifi. It gets stuck on Turning on... Do i have to reflash the rom again and if so how will i do that? It was stock rom on stock kernel. Only rooted. gt i9300t moder and build DUELL2.
Also can i flash a rom with different build over that? For example XXEMC2 that i have on my Greek galaxy s3?
I9300T rooting is the same as I9300 rooting, follow the guides of CF-Root 6.4 or CF-Autoroot. (I got a T model myself)
You can flash any I9300 rom also on the T model, therefore root is not 100% necessary. Full wipes are recommended for flashing different versions though.

For wifi, try a stock ROM (flash it new incl. wipes etc.), or try a different kernel, whereas the stock kernel should always work.

you can find (unrooted) stock roms for instance on sammobile.com or (rooted) stock roms here on XDA in the General section.
Easiest way to flash them is via Mobile Odin (gives you the option to keep root) or Odin (you will loose root but you can flash CF afterwards manually).
And yes you can flash any build that is made for the I9300/I9300T.
The only difference between both models is the frequency of the baseband (the T model is more optimized for 850mhz) whereas you even can use modems of the I9300 on the I9300T.

There is a difference between the ROM's firmware (basically your OS, e.g. XXEMC2) and the modem (basically the part which gives you the connection to the next mobile tower and is managing the frequencies, e.g. DUELL2).
It does not matter that much what ROM firmware you use as they are nearly identical in each country (here and there dif. apps due to providers) but more that you use a modem that delivers in the country you are in. Hence, I would first try the modems of your region (you can find a list of all modems in the General section's modem collection).
Regarding the risk of bricking: there is always a risk, no one can guarantee you anything , whereas if you follow the guides you should be fine.

The firmware code (XXEMC2) should not be of concern.
The modem code (DUELL2) should be of concern IF you experience bad performance in the region you are. If so, flash a different modem and try it.
The phone will be an I9300T whereas in the menus it might tell you I9300, anyway there is no difference in the files to use.
For rooting, follow the guide, you can use CF-Root 6.4 (if you want a custom recovery) or CF-Autoroot (if you want to use stock recovery).
