Flashing back region specific modem - Galaxy S II Q&A, Help & Troubleshooting

Hello,
My S2 originally came with Android 2.3.4. I then decided to root and switch to a custom ROM. I'm currently running Hydra-H2O Rom, AOKP, and I noticed my baseband is not the same as it was anymore (originally phone: I9100UHKG4). Now, after upgrading, I noticed that sometimes my data connection would drop, and the carrier menu that comes with the sim chip (Sim Toolkit) stopped working (i can access it, but it wont communicate).
So, I guess my question is, can I flash the modem part of the original GB stock rom and will that fix my issues?
Thanks for your help

Yeah, you get the actual modem file and either use Odin or ClockwordMod recovery to do it.

Thank you bro, although the modem for my region/carrier does not appear on any of the links listed in your post. It didn't matter because I already extracted it from the original stock rom downloaded directly from Samsung.
I am currently running baseband UHKG4 with no problem, however it did not fix my issue with the Sim Toolkit menu. I still cant use any of the options on it. Maybe it is a chip problem, go figure
Regards,

useful info.
so, this means that even though people say the models i9100 and i9100m are hardware identical, in fact they are not. the proof would be that the i9100's modem corresponding to a region, for example to europe (with LS6 and LS8 supposed to work) does not work with i9100m designed for canada (here, MUGL3 and XXLQ6 are appropriate).

Don't worry, sometimes it doesn't even work for I9100.

That's bs.
Read my signature.
Mugl3 modem is out performed by ld8 modem on my phone. Location does not dictate model. The i9100 is the i9100, whether you purchase in Canada (the 'M' suffix) or elsewhere.
You choose the modem that works best for you and your phone. Period.
Don't be twisting words around to suit your theories.

Bell Galaxy s II: constantly switching from 3g to h+?

Hello gents.
I have a 1 dag old Galaxy S 2 and it's all good so far. I have a question. The phone switches from 3g to h+ automatically. The it seems that when I am not actively transferring data it stays on 3g then as soon as I start downloading or browsing or whatever it switches to h+. Is this a battery saving feature? I the reason I ask is that sometimes it seems to be in a loop switching from 3g to h+.
Thanks!!

I'm having the same issue, but only since I updated to KG3. Originally I rooted my phone with:
CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4
No issue with H+ / 3G.
I then installed Lite'ning Rom v4.2 XXKG3 and the issue started. My modem (PHONE) was then updated to KG3:
PDA: I9100XXKG3
PHONE: I9100XXKG3
CSC I9100XEUD1
I reverted to a stock XXKG3, same issue.
First thing I did when I rooted with CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4 was to backup everything. I reverted to my backup but obviously the modem remained the same:
PDA: I9100MUGKG2
PHONE: I9100XXKG3
CSC: I9100MBMCKG2
But I didn't have the issue anymore! So the modem update is not a fault here.
I did try to switch off fast dormancy, but it didn't change anything.
As you said, the phone goes to h+ when it starts transferring. My results with Speed Test remained the same, so I'm not to worried about it. I don't know how this impacts the battery. I can't really compare since now I use different cpu voltage.
Hmm. I will try downgrading to a KG2 kernel. Is this even doable / safe?
Thanks!!

Yes it is, download the stock kernel here:
http://forum.xda-developers.com/showthread.php?t=1075278
ZSKG2
OR
XXKG2
Then root with the correct ChainFire kernel:
http://forum.xda-developers.com/showthread.php?t=1103399
Please note that this wouldn't revert you to the exact software that was on the phone when you purchase it. The stock kernel from bell isn't available for download. Please note that I didn't try flashing to KG2 (only KG3) but I'm sure it's pretty safe.
Teslarage,
what are you running right now? You might already be to KG2... do *#1234# on your phone and past the info here
Thanks for the quick replies people!
I am running Cognition 1.31 with the ROM built in kernel which I believe is nepamphetamine (or something similar) along with the kg3 modem.
Would it be safe to downgrade the modem? I or should I try with a different kg2 kernel?
Sent from my GT-I9100 using XDA Premium App
I tried with a different kernel, no cigar. Same issue...
Weird.
I'm pretty sure it's the modem. Any way to downgrade it? Flash the previous one with Odin? Which modem should I install?
I rooted my Bell SGS2 within hours of getting it, but I'm pretty sure it wasn't switching (3G / H / H+) before I rooted it and installed a custom ROM. It is now.
Some people here say the switching is normal, however I'm pretty sure this didn't occur on the stock Bell firmware. Maybe someone who hasn't rooted yet can confirm.
I've tried many roms (Villian, Cog, MIUI, DevNull) kernels (CF, Ninpo) and radios/modems (KG2, KG3) and the issue remains. I'm pretty sure the stock Bell firmware, specifically the MODEM, was customized and since it's not leaked we're SOL. My stock Bell f/w (modem and kernel) was MUGKG2.
I'm pretty much a noob when it comes to Samsungs, this is my first so I'm learning as I go here. But I've owned a few HTC's and never seen this issue. My Desire ALWAYS stayed on H with the same SIM card and on the Bell network.

You can flash any modem you like with ODIN but I assure you I've tried and the issue remains. I think we need the MUGKG2 one.
I flashed kernel oz_kg2 to root and unlock and I always have the H+ on. I don't think it should be anything to worry about since this technically is saving battery. Can you guys confirm that your phones aren't affected by the AOS bug on KG3?

Did a quick search for AOS and nothing much useful. Something about battery drain? Mine seems ok.
I wouldn't be concerned with the switching modes if I wasn't also getting intermittent connection problems. Sometimes it seems as if my data just disconnects. The data icon remains in the status bar but I can't surf, download market apps, check gmail, etc. Usually have to reboot.

Argh. I can't wait until somebody releases the stock modem / kernel / firmware for Bell. I'm going to flash back for sure. I find my WiFi performance pitiful on every ROM I've tried and the issue at hand in this thread is incredibely annoying
It's not the modem the problem, if a revert to my backup
PDA: I9100MUGKG2
CSC: I9100MBMCKG2
There is no switching with a KG3 modem
Maybe it's the CSC file since it's related to the country and carrier related settings? Any way to extract that data ?

I did peak at /system/CSCFiles.txt of the bell stock rom but didn't see anything striking... Only saw the bloatware from bell: UNO, nova, the gps app, selfserve app, etc.
To see if the CSC was at fault I tried upgrading to two different version of CSC but the update failed each time... not in odin but when the phone reboots for the first time...
Im also unsure if my gs2 is at fault or if its Bell's network. My d/u speeds are very inconsistant. Last night I was getting 5 down and 2 up and to day I tested with my bro who has a HTC incredible S on Telus. He got 8 down and 3 up while I was at 4 down and 1 up. What I found striking in that test is that telus uses Bell's network and that his phone is not 4g. I should be getting better speeds I think. What do you guys think.

[Q] Newbie --India --Three Network mobile -- Basic Questions

Hi All,
I bought a used galaxy S2 I9100 yesterday,new to android.I have been a iphone user for 4 years and pretty aware of jailbreaking, unlocking installing custom firmwares. the terminology here in Android world is different though.
Have searched and read through different guides on the forum but still got some questions.
Model GT i900 LKAH3G
PDA i9100XWKE1
CSC I9100H3GKD4
Kernel 2.6.35.7-I9100XWKDD-CL161513 [email protected] # 2
Build Number GINGERBREAD.XWKE1
Looks like it was on Three network but it is unlocked mobile as i can use my airtel sim on the phone.
I dont want the Three network related stuff on the phone so i need to debrand the phone -- how to do it? there is guide on XDA forum but it talks primarily for O2 phones or might be i did not read it correctly. (there are also some options like the network mode which are disabled on this ROM )
Once debranding is done should i be ok to use any ROM or kernel?
Which would be best ROM to be installed and will it work for me in India.
Can i install the custom ROM and would i be able to install apps from the android Market.
If these have already been answered , can you please provide the link for that thread.
Thank You
I'd advice you to try the new ics roms, you can find the instructions inside the various rom threads, flashing these roms will get rid of the three junk as well as update your phone to the latest android os a.k.a ICS ..........
there is no such thing as a best rom for a specific country, but you can try different modems to find the one that gives you the best network and battery, you can find your modem under the baseband in about phone....
google for more info
happy flashing and welcome to Android we luf you here...........
Learn how to use Odin
Download stock gb from from checkfus or sammobile.
Flash using Odin, you will be unbranded.
After that root using cfroot, now learn how to use cfroot.
Now you can flash custom roms.

Hi KJplasma &atifsh
Thank you for the details.
can i install the below listed indian stock firmware using odin
PDA :I9100XWKE8 CSC:I9100ODDKE2
or do i need to install the firmware from UK
PDA :I9100XXKF2 CSC:MULTIOXAKF2
do i need to change the csc if i install the UK version?
Thanks
forget about csc.
if you have i9100 you can flash any region ROM and use in any country.
if you want Gb than go for la2 italy rom , iv used that and last time i check that was the fastest stock rom for GB
you can also flash ICS rom like uk lp7 too, just stay away from lp9 roms at the moment.
ad dont forget to wipe using the dialpad code *2767*3855#. [will wipe all data stored]

I have tried to do a factory rest from the phone's privacy menu but even after everything is done,istill see some files in the gallery.
i tried the code *2767*3855# everything goes fine but i see the message "cant access to system\csc\h3g\system\" and then the phone strats as normal.
can i flash it to the OS even if i am getting this message using odin or do i need to
do something before i flash?
factory reset will not delete your user stored data on the SD card...that can be manually deleted...if you want
you can flash the OS from ODIN
thanks for the responses.
I have upgraded to I9100XWLP7_I9100XEULP, and its working fine. the only problem seems to be its heating a bit where the camera is located . will read more topics and see why this is happening.
thank You.

Yes though the newer dxlp9 was much better, previous one had bunch of issues including sleep of death.
Also that ROM introduces the contact/dialer lag bug. Which some how got to Google account and now every time I sync contacts it get back.
I deleted all my contacts and synced again and it's all better, tried on dxlp9 and was working fine, than I switched to my regular cm9.

For a start, if you remember your last ROM that doesn't had heat issues, flash that modem. Doesn't matter if you use GB modem on ics.
I flashed the modem of my region xxki4 which is 2.3.5 jpkj2 and had no issues of heat in ics.

[Q] SHould I change CSC to my original UK provider

Hi
I'm just wondering if after flashing a new custom ROM (or indeed I started to mod my own rom from Wanam's de-odexed latest stock rom) should I flash my original CSC from 3Hutchinson UK (H3GALE4) or stick with the latest unbranded UK CSC? It's still unclear to me precisely what the CSC does?
Surely it is the radio/modem version that determines connection speeds/efficiency of the modem etc? Or could the CSC have special 3 mobile firmware for getting better connection with their network? - Or what I suspect is that it just loads the 3 network boot screen and installs the 3 app?
Thanks

Afaik csc file determines the country code and what apps are to be installed per country that samsung assigned, like bbc player for the UK. But it`s not that important to be honest.
Thanks,
So only the CSC is carrier specific? Radio/Modem is purely just firmware for the radio and modem? I ask because in the UK 3-Network transmit using UMTS (not GSM) on 2100MHz so I wondered if there was anything that could optimise this. It seems to me that ALL 3 phones in the UK use the NELE4 modem - is there a reason for this?
I'm on 3 in the UK had it for a few weeks now on le8 and le4 modem rooted and changed the kernel to siyah but don't want to flash a custom Rom yet for the csc reason and seen in a few places people losing imei number too is that them just being completely dumb tho and flashing incorrect roms etc?
Sent from my GT-I9300 using xda premium
I had read the same although I took precursive efs backup and immediate image of my initial stock. I've flashed through some nice ROMs but recently decided to make up my own from one of Wanams deodexed stock roms. However I have really liked the Omega rom so I may roll with that, but I have been reflashing the CSC to 3 H3GALE4 thinking perhaps it improves things for 3 users??? But I reckon moreliekly just provides the 3 splash screen on power up.
My interest in modems and/or CSCs is that my primary reason for the sgs3 is not so much a phone as my home internet provider as i live in v rural area yet with an anttenna I can get above 5mb/s whereas my land line can barely provide 1mb/s. So any modem/mod/hack which specifically improves this and perhaps even the software/driver behind tethering is what I'm keen on learning about.
Great phone though.
Amazing phone couldn't want more gui is so smooth I have from some where got on my internal sd a efs-backup.zip so I will back that up and try checkrom worst comes to I send it back
Sent from my GT-I9300 using xda premium
Well I tried Checkrom and that too is really really good. Prior to flashing a new custom rom I followed the instructions of flashing back to original stock and triangling away which worked absolutely fine too.
Yeah already tested triangle away works wonders with siyah kernel it dont even need to restart the phone great work on that chainfire

I'm sure whether or not I get terrible 3G speeds without the 3 modem or not
Poor speeds is often modem related try BULF1.
CSC can be copied out of original rom and replaced in a custom rom before flashing .
System CSC folder and CSC version text .
CSC is not required for a phone to work and is only a list of local area network connections on stock .

Been running Turkbey Custom ROM for a month now, and 3 mobile CSC was not available in this ROM but it has had no effect on anything and everything I do, and installed bbc iplayer and 3 network app automatically, so I agree CSC is not that important.

Thanks for info. I'll try BULF1 in my little ongoing tests.
Does anyone know of a custom mod/app that replaces the stock "tethering" software with a better one? I ask because I can get 10Mb/s mobile data connection on the phone but when I tether my laptop, that will only reach 4-5Mb/s. I want my phone to act as good modem router - seems the stock one isn't as good as it could be??
I'm on 3 UK, using Omega10, all modems included with Omega worked well, you can try flashing any modem, I'm currently on lg6

I've been at sea for anumber of weeks so I have only just caught up with this thread again. I have tried a number of modems (and given them a few days to "chill out"). All though I still do not have any quantative proof it *seems* as if the original NELE4 modem works the best - by best I don't mean connection speeds but in the UK without moving location I seem to get H+ more consistently whereas other modems would *seem* to jump between 3G, H and H+ more randomly. These are only thoughts - my observations may be completely wrong. WOndering if anyone else has noticed similar?
Even if I am not in the UK, I would like to confirm my understanding of CSC as I just found out that my phone's status is CSC: unknown after I flashed the newest 4.0.4 update for my region (TH, I9300T).
As I understood CSC does not impact the phone a lot, only the region specific play store settings and networks. Currently I face no problem with the phone at all, normal reception etc., hence would you still recommend flashing the correct CSC to remove the "unknown" status or just keep it like it is and wait for JB later? (I am aware that CSC flashing will format my phone)
Thanks

I really am not the best person to answer this I am afraid although does reflashing your CSC really format the phone?? I thought you could use ODIN to just reflash a CSC and leave the modem and FW intact but I may be seriously wrong so don't do it on account of what I've said! Hopefully someone will clarify.
As has been said by others on this thread (many thanks) I really doen't think the CSC matters that much at all - the only difference I notice between the 3UK CSC (H3GALE4) and a non-branded UK CSC is that I lose the Three logo on boot and BBC Iplayer and Twitter App aren't installed.

The first one after getting updated to 4.1.2 wifi stopped working but i found a fix installing the wifi folder from 4.1.1 version. To that I need root though. So any help on how am I gonna root them both? Cause I couldn't sort it out my self.

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.

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

Can you tell me how i will flash a new stock rom on it? where can i find the stock rom and can i flash a different build?
DUELL2 is the current.

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.

What do you mean by modems? Soz if I sound noob but I am new to Galasy s3. My previous android was ideos x5 and i had a miui rom on it.
The phone will be used in greece. Do you suggest me flashing the XXEMC2 rom that i have on my Greek S3 atm? Is there any chance of bricking it if i flash that rom on it?

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.

Ok. Here is the deal. My greek galaxy s3 which i recently updated is XXEMC2. The galaxy s3 with the wifi problem is DUELL2 bought in australia from a friend but will be sent to greece for my brother. So i should flash XXEMC2 on it? I just download XXEMC2 from sammobile and flash it with odin? It doesn't matter that the XXEMC2 is for i9300 as fas as I understood from what u said. right?

correct, you can use the I9300 versions of any rom for the I9300T as well.

Ok. So the CSC numbers that are different on lets say the DUELL2 and the XXEMC2 are not something to bother me right? I just download the XXEMC2 rom and flash it on the DUELL2 S3 and then I just will root it. right? Will the phone become i9300 after that procedure? or stay i9300t? So I know which file i should use to root it.
Soz for too many questions but the phone is not mine and I need to be sure for the procedure.

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).

Thanks a lot mate. This helped a lot. I decided to go with the 4.1.1 version of its current region. Later if we see that it doesnt perform well here in greece we will flash the xxemc2 rom.
Ok i downloaded the rom from sammobile and the file name is this I9300TDUDLK1_I9300ZZZLK1_VAU.zip but i get an error message that says cannot open. file unknown or damaged :/ Why is that? Is this file meant to be named as md5?

To flash a rom via odin you need the md5 file, correct. Hence unzip or if you cannot maybe the download is corrupt?

The zip file was probably corrupted. we will download the greek version XXELLA after al...l. Cross fingers for success
btw should i make an efs backup to be surr???

Galaxy S3 Android 4.3 no signal

Yesterday I updated my i9300 to android 4.3
Baseband version I9300BUUGMJ3
Build number JSS15J.I9300XXUGMJ9
..and since then I haven't had any reception. My imei number, serial number, and everything else is same and still there, but I just can't get it to get reception again... When I go to my Mobile Networks, it says registered on network, but again, no reception. Then I tried installing the modem BUUGMJ3 with odin which didn't work. What can help? Stock firmware? Please help.
Thanks in advance.
currently experiencing the same issue mate. I can't seem to find a workaround/solution for this -__-
Is that base band supposed to work in your country? Find an modem later than EMGx, without a RIL, for your country and install that to test.

I've probably made a big mistake there, no it's meant for mine country, it's for the county near mine, Croatia, but I read somewhere that this doesn't matter.. :/
And by 'later than EMGx' I'm not sure what you mean, but I've flashed EMG4 modem which didn't seem to work.
Found something about flashing a previous modem and restoring your EFS folder, but I do not have my EFS folder backed up - I forgot to.
A few days ago I paid about $30 for a repair on my phone, I don't really want to send it off for repairs again, I really wonder if there is an fix to this
Follow the guides in general forum, stickies on how to flash back to 4.1.2 stock rom. Make sure it's at least EMG4 base band.

Yeah, about that...
first of all, sorry for bugging you so much..
but I downloaded the right stock firmware for my country, I9300XXEMG4_I9300BHTEMH1_I9300XXEMG4, but after I flash it via odin when the phone turns on it gets stuck in a loop showing the Samsung logo repeatedly...
Edit:
Okay, I managed to install the stock firmware 4.1.2 but it still is showing 'Emergency calls only', the modem is xxemg4...

how about your IMEI/Serial numbers? are they still the same before you downgrade and flashed the XEMG4 modem? mine are the same with SN/IMEI so I guess that's why it worked. I just took the risk cause I was really pissed experiencing the lag and the battery drain in 4.3.
Do factory reset from settings option in touch wiz, make sure the imei and serial number match the label under your battery.
If still no good then try another SIM in your phone, final steps would be restore efs backup then repair centre.

Well it's all the same as it used to be. Could it be that the modem I had before EMG4 changed the format of my efs folder?

Did a factory reset, imei, s/n same.
Android 4.1.2 EMG4 modem still no reception.
It seems that MGX modem has change ur IMEI from /efs1 to /efs2. MGX modem seems to support only 4.3 roms (due to some security issue).
It is not recommended,but u could flash an older rom with modem (get from www.sammobile.com) then restore an efs backup (if u did some) from /efs2 to /efs1

FYI: My serial Kay or IMEI is not 0000 they are fine.
Here’s the list from Setting->About Device->Status<br>
Network: unknown<br>
Service State: Out of service<br>
Mobile Network State: disconnected<br>

Ariza patch only works on older modems (efs v1 modems). So, that wont help.
You said you flashed the zuluman modems but.... did you flash the patched kernels too? You need the patched kernels for the patched modems to work. I don't know why, but that's what zuluman says (according to him, the kernel has a modem signature check and it wont work if the modem was modified).

Here are all the patched modems and kernels made by zuluman.
https://drive.google.com/folderview...&usp=sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8
In my opinion you should flash the latest official firmware and download the appropiate modem and kernel from that google drive.
You can download the latest official firmware from the general section of this forum.
Good luck.
Remember to always have an efs backup!
Great thanks!

Flashing the Modem + Kernal after rooting the Phone works for me. I have flashed it using CWM.
Thanks once again.
the same problem with signal
hello,
i've the same problems with my s3. i flashed it OTA to Android 4.3
After this i had no signal. ...
When i found this thread i was so happy. BUT!!!
i downloaded all the modem and kernel files from the google drive and wanted to flash them (Patched_XXUGMK6_xxx.zip) with cwm recovery (latest version).
whenever i want to do this, i get the following message and the update aborts: "E:Can't copy META-INF/com/google/android/update-binary"
what can i do? Can i flash them with odin, too? Or does anybody have another idea?
here are some Infos about my Phone:
Android-Version: 4.3
Baseband: I9300XXUGMK6
Kernel: 3.0.31-2191747

hmm...
can nobody help me? ...
sorry for spamming, but i've got a problem without a phone
greetz,
Carpe.
You said your imei & serial is ok but you cannot register to network. Have you paid your bills?
But if it's corrupted serial number.
Try this guide.
thx for your answer.
Payed my bills? ... uuuuuups!
back to topic: i've flashed my phone back to 4.1.2 for the moment. Network seems to work. ... i'll try some things and give a feedback here. ...
You have to flash an Android 4.3 modem for it to work I think but as your on 4.1.2 now I guess it doesn't matter anymore
