Hello.
I've been running Cyanogenmod 9 for a week or so now, but today I wanted to check out the Checkrom ROM and see if it was anything. It was not and I've already switched back to Cyanogenmod again.
However, when I flashed Checkrom I apparantly also installed a new basebandversion called I9100XXLP1, previous I was using the one called I9100XXLPQ.
Does it make any difference which I use?
As far as I can understand baseband versions are the same as modems, which I've seen people talk about in other threads. I haven't really experimented with the different modems but I'd like to know if I should try to revert back to my old baseband version, and if so, how I do it.
Cheers!
Yes Baseband and Modem are same, wich is a part of firmware controls GSM, 2G/3G data etc.. of your phone.
if you are not feeling any difference in your data speed and signal strength, it is not necesory to change back.

Some custom roms contain Modem also, which replaces your exising modem, but CM9 does not contain a Modem, so your last flashed Modem (with checkrom) will be there even after flashing CM9 back
Thanks. That was enlightening
I haven't really experienced any difference regarding data speed and signal strength, but in case I do I'd like to know how to change it back.
I've found this page containing links to the various modems: http://forum.xda-developers.com/showthread.php?t=1544487
Can I just download one of those and flash it?
And does it make any difference if it says 4.0.3 under firmware instead of 4.0.4 which I am using?
No the link you quoted is not for Modems but its is for ICS official ROM,
I think you have lot more to learn about to the firmware versions and parts of firmwares and more....
dont rush for any unecessory flashing....fist you learn as much as psooible by reading the informations FAQs

Hi,
Sorry for this post, but I tried searching, I am new to all this android stuff.
Basically I got a Bell S2 that was at 2.3.3 I rooted it by flashing CF-Root-SGS2_JP_XSG_KG2-v4.1-CWM4 and unlcoked it successfully. I now want to upgrade to 2.3.4 and was wondering what the best way to do it would be. I would prefer to keep it rooted and the apps that I have installed intact.
My questions are:
1) If I flash back an official firmware will my phone still be rooted? If so what is the best firmware to use?
2)Is there another custom firmware that I should flash to upgrade to 2.3.4 that is compativle with bell and also rooted?
Thanks
Pick a rom from the dev section and install, that would be the easiest way, and use titanium backup to backup your apps.
Thanks for the reply! Which kernal would be the best to go with at the moment? I have no idea which one to choose!

Okay, so my device is running 2.3.3 right now, and it currently rooted and unlocked (did this myself). How would I go about upgrading it to 2.3.4 and having it rooted and unlocked still? I am in Canada using a previously Bell branded phone that I am now using with Rogers Any help will be greatly appreciated!
Whichever kernel that suits your needs, the speedmod kernel seems to have amazing battery life but has no bln support, while the ragemod kernel has a bit worse battery life but supports bln.
Download one of the roms from the dev section and follow the install instructions that are posted, all the roms are rooted and will keep the phone unlocked.
Hey there, guys! First off, yes I am a noob with this kind of stuff, so I apologize 1000 times in advance. Secondly, I have searched, but to no avail (and my great confusion!) for this, but have found nothing. I have a SGH-i717D, Canadian Telus variant of the Galaxy Note. I rooted it, and all went well. Having said that, I didn't flash any custom ROMs (after attempting a stable version of CM9.1 which sent my phone into a boot loop), and decided to unroot my phone and now I currently have it with what I assume is stock Telus 4.0.4 ICS firmware. I was wondering if anyone had a flashable .tar of the Telus ICS 4.0.4 Kernel?

Thanks for the links, but I'm a little confused. Will the modem and radio reset my kernel? Currently my LTE and everything else works fine (though my phone does tend to freeze now after I send a text sometimes :/). For reference, here's what my phone says under About Phone. I would like to get everything here back to Telus' stock ICS.
Sorry for the bump, but it now seems that my phone will sometimes send the same messages multiple times. Last night my cousin reported getting the same two texts 5 times each, which is something my phone never did before. My phone's APN settings are still the default Telus ones, so I'm not sure what it could be. Could this be a result of anything I did (namely rooting the phone and installing CWM before unrooting)?
hey there,
are here some bob-austria-users using cm on the sgs2?
which modem do you use?
i have so much trouble with my data connection and even sometimes with gsm...
wär für jeden hinweis dankbar!
ps: radio/modem is independent from the rom and its version, isnt it? or does the rom-version affect the quality of the modem?
tyvm!!

Goto http://samsung-updates.com/device/?id=GT-I9100 and look for the BOB/A1 Austria code (ATO). Click the link and you'll see that XWLPW was the latest Samsung ROM for the i9100.
Download it, flash it, look for the modem that goes with it, reflash your CM10.1 backup*, download the modem, done.
You'll now have the modem of your provider. This should be "the best". However, "the best" is a relative thing: what is the best for you, may not be the best for someone else. The only way to find out for yourself is to test signal strength and data speed in different locations and at different times. Possibly you're in a low reception region. And when you're roaming, a totally different modem may be best for you.
Or ask in http://forum.xda-developers.com/showthread.php?t=1131950.
Modem XXLQ6 and XXLPS were good to me. Try them. Now I'm testing an old modem of my provider (see my signature).
CM doesn't come with a modem, since it is used all over the world with lots of providers. If you're clever enough to flash a custom ROM, you'll be clever enough to find your modem
Maybe there is a modem/RIL mismatch. Install GetRIL free and flash a matching RIL. See also http://forum.xda-developers.com/showthread.php?t=1187681 and http://eric10234.wordpress.com/2012/10/23/samsung-galaxy-s2-i9100-jellybean-cm10-real-ril-crash/. Don't be scared about the RIL crash thing. It only happened to me with LS6 modem and/or RIL.
*When using stock Samsung, you maybe first have to flash a rooted kernel to get CWM Recovery. Use the method described in the CM9 thread or just flash the whole CM9 ROM using the Odin method.
Tip: when asking for help, always give information that is related to your problem.
So: what modem are you using; what modems have you already tried and what were the results; are you still on CM9 as your signature is suggesting? Also give general information like phone model (obvious), ROM name and version (saying latest nightly is silly, always name the date), modifications.
Edit: just finished downloading the XWLPW A1 Samsung ROM, extracted modem.bin, entered a hex editor, searched for the string xxl and found the text "120626.I9100XXLQ6". So I'm assuming that modem XXLQ6 comes with A1 Austria.
thank you for the detailed explanation...
i will see into it..

Hi everyone,
We're very lucky in that the different model carrier/international variants for the G2 have similar hardware other than radio differences and the Korean variant having micro SD.
If we just used our own kernels (which I assume may be a little different accross carriers) couldn't it be easy to set up flashable zips for each carrier to set up provisioning/data/gps? There are some guides on XDA on rom porting for other phones
Not a dev myself, but was wondering what information from each stock rom could be useful to help make this easier
Yea on the vzw galaxy nexus this guy made a zip to flash gsm roms on toro and all u had to do was go into the rom change thename from maguro to toro n zip it back up, flash the rom then the .zip n u were good.
---------- Post added at 09:44 PM ---------- Previous post was at 09:39 PM ----------
Although on the gnex the kernel was the same across variants so if someone wrote a similar script for the g2 u might have to flash a vzw specific kernel after flashing the international rom and the .zip
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.
