Hi,
I installed a custom ROM AOKP build (the thread for which has either been deleted or I'm failing at finding it). The ROM is generally good, except for batter life. I was on GB checkrom v6 before this, and had the same problem. On that ROM, I used the kitchen app to update the baseband which vastly improved my battery life, and I'd like to the same on JB, but as that app only worked with checkrom, I don't know how to go about it.
Can anyone tell me if I can use any baseband I like with the JB ROM, where I can get different basebands from (I think the one that worked well was KI1 or KI4, the XEU ones for UK/Europe), and how to install them?
Many thanks.

Yes, you can flash any modem, so far it's for galaxy SII, GT I9100.
There it's nothing like gingerbread, ICS, jellybean, AOKP or Aosp baseband/modem
The only modem we have is galaxy SII modem and they are compatible written our phone irrespective of the Rom/Android version
How to flash a new modem:
Download the best modem for your region here: forum.xda-developers.com/showthread.php?t=1131950
-boot to CWM recovery
-flash the modem zip file you downloaded
-reboot phone
Done
Note: Baseband is also called modem
Swyped from my Galaxy SII
Excellent. Thanks very much, I'll give it a try!

Hi SGS2 users.
I have been using my stock SGS2 for approx. 1 month now. I have been following with the forums but have yet to do anything with my phone. I have experience with flashing (had an old HTC Diamond 2 using WinMo and did quite a bit of flashing a few years back. I switched to blackberry and has recently returned to xda.
I am completely clueless with the android flashing. I HAVE rooted my phone already though.
So I have seen some tutorials on flashing roms (most are included in the rom description) but what is this kernal flashing. I keep hearing certain kernals performing better then others in terms on bat life and speed.. (such as the nimephatimine(not sure if I have spelt it correctly). How do I use this kernal stuff? Please link me to a tutorial thread if there is one, I tried searching and was unsuccessful.
Any recommendations on ROMs? The top 2 I see are cognition and litening..
Cheers

theres a nice guide there for the basics of flashing with odin. note this guide is for a complete firmware.
the kernel is just a small part of the ROM and it can be easily changed at any time. you flash it any .tar kernel file in odin as a PDA
It's easy. Download the firmware, extract it, you will get a .tar file, open Odin, add the .tar file into Odin PDA section and Flash it. Simple. A full firmware is around 300 mb.
Same goes for Kernel, you will have a .tar file around 5/6 mb, flash it vid Odin by selecting PDA.
Yes, there are lot of kernels, like you said, Ninphetamine, some others are, SpeedMod, RageMod, Hellcat etc. Each and every one has it's own features. Like Ninphetamine adds BLN feature, Voltage tweaks etc, Overclocking etc. The simplest rooted kernel is Chainfire kernel, it's basically a Stock firmware with BusyBox, SuperUser and CWM and I recommend it. But if you want a more versatile one then I recommend Ninphetamine, which I am currently using.
Read about the Kernels under Dev section for more details.
Regards.

if you are looking for a stable Samsung ROM go for Cognition, LEOMAR or Litening. If you are interested in cooking your own rom you can for the ROM kitchen. romkitchen.org/beta
In case of AOSP or CM ROMs you have CM7, MIUI, Oxygen etc. CM7 is not stable. MIUI looks good but is a battery drain for me.
As far as kernels for Samsung ROMs go Speedmod and ninphetamine are the popular ones.

MIUI is built on top of CM7. Meaning it's equally as "not stable".

I have the following Galaxy s2:
PDA: XXKH3| Modem/phone: XXKH3| CSC: OXAKH3
Rooted and Siyah Kernel.
I was wondering if there is a way to get ICS update through Samsung Kies (when I plug the phone in it keeps telling me it's up to date)?
I want to keep all my setting and data.
I know it's possible to do it through Odin but all my apps and data will be erased
If there is no way to update using Kies what is the best/latest stock ICS firmware available now? Which one will get the latest updates first?
you can backup your apps and data using Titanium backup and flash a Custom ICS rom from CWM
latest stock is XWLP9 and reported very stable...you can get it from here Rooted and CWM flashable : http://forum.xda-developers.com/showthread.php?t=1292825
don't really want to keep backing up the app every time there is an update. I just want to go back to stock...

You answered it your self, custom ROM......
Stock is buggy. Dxlp9 is good
I kind of want to go completely stock as I mentioned so when new version of Android comes out I can just update using Kies. Don't really want to deal with all backup and restores.
FYI, there is no guarantee a Kies update won't screw up either though. Always a good idea to back up before an upgrade, be it a Kies update, or an Odin flash. And if you're going from stock to stock with an Odin flash, that won't wipe your phone anyways. (still a good idea to wipe anyways, though...)
2mrw I'll be getting my brand new I9100T
Now I'm not asking which rom is best ^^ so no infraction needed
...rather...
should I upgrade to official ICS before trying out other roms? or is gingerbread stock a better launching pad?
can we downgrade from ICS?? (I'm assuming b/l is unlocked)
is there a baseband app for SGS-II (like my defy has) -=or=- will I need to manually copy it over?
PS - if it is recommended to officially update... is KIES or CWM better for this?
T.I.A
stock gb for now later u can upgrade to anything
1) Not necessary. Follow whatever instructions the particular rom you want to use has.
2) Yes, you can downgrade from ICS to GB. Simply flash whatever GB rom you want to downgrade to.
3) Baseband app ? I presume you mean modem. Flashing any rom shouldn't change your modem, and many of the GB modems work just fine with ICS I.E modem/baseband is independent of rom/kernel. I'm still using the modem I used with GB, essentially unless you have issues with connectivity/data/calls/SMS that you can't pin down on your carrier's network, no need to change your modem. In saying that, modems are CWM flashable (you can also flash them in Odin), so if you do have connectivity issues & want to try other modems it's pretty easy.
Now, if you meant something else by 'baseband', explain what you mean & I'll try and answer whatever questions you have around that.
@ MistahBungle
On the defy your radio/baseband/modem/yabba_dabba_doo
does change when changing rom - defy has an app for restoring the above...
as it's all android, I'm sure I can do it manually on the S II
so no-one see's official ICS update as beneficial?? Surely it's less buggy than a CM9 -=or=- a MIUIv4!
PS - which recovery should I flash for I9100T??
PSS - Think I'll try MIUI 2.3.9 for a start after I get bored of stock
OK so the modem/baseband is the same thing. On SGS2, roms normally don't come with a modem (I don't think I've seen a single one that has a modem included), these can be changed/flashed independently of the rom/kernel you're using. Again, my advice is if it ain't broke don't fix it; if connectivity/data is fine with the modem you're currently using, no need to mess with it. Yes, you can change them manually yourself easily; most modems are CWM flashable & take a minute to flash.
Whether official ICS (or even a custom ICS rom) is a 'step up' or not depends on how you experience same, I.E. YMMV (like any rom or kernel really). Only way to find out is to try one, which is pretty simple once you've rooted your phone; you can backup your current setup in CWM then try out whatever rom you want. If you find you don't like it, takes only a few mins to restore your backup.
If you use CFRoot to root your phone, it installs CWRecovery by default, which makes backup/restore & flashing roms/kernels/modems a snap. If you do choose to use CFRoot, read the whole first page thoroughly, it's very simple if you pay attention/follow the instructions.
was going to root via 'new' method i.e. .bat file - suppose to root all S 2 variants... it doesn't install CWM but I can do that via Odin...
you use touch recovery??

Up to you, use whatever method you're comfortable with. Touch recovery ? Have used it when I've used Siyah, but not at the moment as I'm using CM9 kernel. Happy to use it if it's part of a kernel/it is good, but personally can't be arsed installing it seperately if it's not.
@JJE Roms I've used haven't had modems (Yes, stock does.) I.E GB Galnet Miui & CM9 don't.

All GB custom roms i have used have modems likewise every ICS custom rom.
Galnet Miui & CM9 only ever tried once so you are probably right for those two . But apart from those sort of builds i have never come across one without a modem . last ten ICS builds i tried have a modem .

i have a 9100t telecom phone,but 2degrees as my provider so i flashed the baseband 9100tdukf4 to get better batterylife with vodafone and 2deg frequencies.
what i did with mine first, i flashed siyah 2.6.14 kernel with odin then used cwm to backup my telecom rom and then flashed away
will manually backup modem ;-) just in case is needed for custom rom...
now another Q: what's all this talk I've been seeing of an internal SD? ^^
How does this affect modding i.e. backing up, restoring nand, flashing roms etc?
well... well... well... 3 holes in the ground ^^
had my 1st soft brick
tried rom manager SII recovery flash (just wanted to see what it would do... just in case it worked) soft-brick...
then flashed CWM via Odin (source galaxy2root[dot]com)
& all is good...
O/C'd to 1.4Ghz with Tegrak & Linpack giving 55+ MFlops!!
Use stock for a wee bit & then I'll get into roms...
PS -Juwe11 RAM script working a treat ;-)
rom manager from the market? i should of said not to use those , i hear they can softbrick the s2.
disable your anti virus while flashing too, nod32 stopped my flashing,soft brick.
hello fellow xdas
while back i had gotten my hands dirty with the CM10 project as i just couldn't wait for the official update! i learned quickly that i had serious problems with antenna/reception. i tried carious base bands (as recommended on forums) using GetRil/flash.Odin. this didnt seem to help, even though i would get better reception, my signal was unstable. In the process i tried other roms like JellyBam and had the same issue.
As this is my main phone and i do actually need to call with it, i went back to the stock rom i downloaded. but surprisingly i still have the same issue! GetRil also shows that i have incompatible RIL/baseband. this is what it shows:
RIL: I9100NELP2; I9100XXKI4
Baseband: I9100XXLPQ
FYI: i am located in the Netherlands and use T-mobile network.
so have i installed the wrong ROM or done something wrong in the process... ? does anyone have any experience with this? i much rather have CM10 but only if i can get to call normally once again?
thanks

Use either of the 2 links below to download either the NELP2 modem of the XXKI4 modem, and them flash them onto your phone via Recovery Mode. That should resolved your incompatible RIL issue.

thanks a lot zee54,
can i just go back to my CM10 or JellyBam, install the above mentioned radios and get everything working? or does it depend on the RIL which that ROM is running! I have tried a number of modems when i had CM10, but dont know if i tried those... i did try BVLP7 for sure
Based on this forum right here i need to have the I9100BOLPD ROM as stock for Netherlands T Mobile!

The modem is independent of the ROM, mate. So it wont make much of a difference whether you install the radio on stock firmware or on CM10. You could try using the modems mentioned by zee54 with CM10 and seeing if it helps. Also, give it about a day or so..since the phone tends to take a while to get 'used' to a new modem.

The unstable signal or "RIL Crash" as it it called isn't actually caused by having an incompatible RIL and Baseband (modem). It is a more complicated issue which I don't fully understand myself. But what I do know is that it currently affects all customs roms that are based on CM10 and use the CM Kernel. So switching modems might help recude the frequency of the problem but probably won't irradicate it completely.
You should not experiencing this problem if you go back to stock samsung firmware. If you experience problems you might want to do a full wipe (Data, Cache, Dalvic-cache) before reflashing and fix permissions afterwards.
On a more positive note, I have found that using the Siyah Kernel with your custom rom does seem to eliminate this problem, or at least reduce it occurance to such that I have not noticed it happening.
So personally i would suggest that if you wish to go back to CM10 or JellyBam ROMs, then do so but also install the latest Siyah Kernel for the S2 from here http://www.gokhanmoral.com/
(Here's the XDA Thread for the Siyah Kernel - [KERNEL] SiyahKernel v4.1.5 (v5.0a2))
I am currently running CM10 with the Siyah Kernel v5.0b2 and it is working very nicely
great stuff guys... 2x thanks for both of you!
Zeey54, i just had Siyah v5 Kernal installed, installing the latest JellyBam right now! so lets see what happens. i was suspecting that beside the RIL/baseband there were other factors as i did not see any significant difference between them. but then again i dont trust my judgement on such issues as my knowledge is quite limited.
will send an update with the result after installation in a few min.

installed the BOLP7 modem, overall reception is much better! data connectivity is also better and faster. but i still have some periods which my receptions drops and goes back up, seems like radio/modem crash (if im right). dont know if that is due to the kernel or modem or ...?
the reason i went for BOLP7 modem was because the latest official stock rom from t-mobile Netherlands was I9100BOLPM_I9100TNLLP8_I9100BOLP7, so i thought that would be the best one to try!
will wait a little more to see if this improves as the modem settles.
4th official ROM too much coverage you please make a review ?
need modem
First of all, thank you mate for your hardwork and awesome utility.
I have a Samsung galaxy S2 I9100G , recently flashed jelly bam custom rom. I am based in Saudi Arabia, the reception is not clear and people complain that it is switched off or out of network. I tried calling with another mobile and i got a response that my mobile is switched off, at the same time i checked my S2 mobile , it shows the full signal of the network in status bar.
what should i do? Which modem should i flash. the getRIL shows RIL/baseband is matching (I9100GDDLP5).
cheers

I'm looking to update from Android 4.0.4. My SGH i777 is rooted from last year.
I have the clockwork mod recovery installed from last year. Using AOKP I think.
There's ROM's for 4.3 but I don't see any kernels posted here. Can someone point me in the right direction? Apparently the sg2 has left the limelight for a while now.
Once I get the kernel updated, does anyone have any good ROMs to recommend?
Thanks
ps You guys are an awesome community.
Which rom is a personal matter. You should try them yourself to see what you like. If you want Samsung Touchwiz based firmware, the latest version will be 4.1.2. To get 4.2.2 or 4.3, you will have to go with one of the AOSP based roms.
Since you have a custom kernel with CWM Recovery, just pick the firmware you want to try and flash it in recovery. You don't need to install another kernel first.
Wait, so all I have to do is pick another ROM? That's it? No firmware update?

firmware update? no. Whether 4.0.4 or 2.3.whatever, you already have have root/cwm; all that's left is a some recommended housecleaning*, then flash whatever ROM you want.
*either:
rom-cleaning-script
or:
factory reset
+format system
Mind = blown. Thanks so much guys!
In my experience with custom ROMs, I found that ShoStock3 v4.0 and UCMD8 v2.2 COOKED give the best battery life and stability, but I use the stock kernel for ShoStock and AJK v4.9 for UCMD8 COOKED. CM/PA/AOKP have given me subpar results in terms of stability and, most importantly (for me anyway), battery life. This is not to say that those other ROMs are bad, but for me, those haven't been working out. Your mileage may vary. Just my $0.02.

So you're looking for a rom. The rom you use will all depend on the type of software you like. If you like touchwiz, I recommend Shostock 3 4.0 or the Cooked Rom. If you're looking for a AOKP Android 4.2.2 rom, then I would use the Resurrection Remix rom, but remember, all roms differ on every phone. Not everyone gets the same results. I wouldn't use a 4.3 rom because its fairly new and pretty unstable on some phones, but if you really want to, I got the best results on the Carbon rom, but the battery life wasn't so good. Also, a lot of the 4.2 and 4.3 roms require you to flash gapps, which are the google apps for you phone. If you're looking for kernels, the usually come with the rom you download, so you don't really need to get a kernel. If you really want the extra customization and tweaks, there are some kernels out there, including AJK, Jeboo, and STI, that you can flash. I personally use AJK on a lot of my roms because I found it to be the most sucessful. I am running Shostock 3 with jeboo kernal right now. Shostock 3 has good performance, stability, and battery life and is touchwiz. So yeah, keep all this in mind when flashing a kernal. You don't to connect your phone to the computer or anything to flash a kernel. If you're rooted, you just have to have the rom in your phone storage or SD card and go into clockworkmod recovery and flash. Hope this helps and good luck on finding a rom that's right for you!
