[Please Help] I9100 ROMs on M250s/k ? - Galaxy S II Q&A, Help & Troubleshooting

After all the awesome help from devs and users here, I've figured out the process of rooting my m250s. Now, I HATE touchwiz, so I decided to try and load a ROM that I could enjoy to get away from the stock ROM.
My problem is that when I loaded a new ROM (in this case it was MIUI latest GS2 ROM), I lose all data (let me rephrase, I lose all mobile network data, wifi still works). It shows full bars for phone calls, but the actual data connection is gone. When I go into the about phone section it shows baseband as M250S.EI21, which isn't wrong (although the latest baseband should be EJ04).
Does anyone know of a way to fix the data connection so I can still connect to the data towers but use a I9100 ROM (instead of having to modify the ROMs every time I install one, which I have no idea how to do)?
Thanks for your help guys, so far I've been very happy with all the resources XDA is providing, especially for a korean device.

i'm not sure about this but since your baseband is still saying m250s i'm guessing you haven't changed your kernel yet. try installing an miui compatible kernel(i suggest siyah) then try connecting again.

Now, I HATE touchwiz, so I decided to try and load a ROM that I could enjoy to get away from the stock ROM.

If hate for Touchwiz is your reason to install ROM, why dont you try custom Launchers instead of installing a whole new ROM? There are very good launchers like Go Launcher EX, AW Launcher, Launcher Pro etc. Try them, once you get bored of these launchers, go for ROMs.

Good point, but I really like the interface of MIUI. If I can't get this to work then I will probably go ahead and resort to different launchers and try to find other things to use instead. Thanks.

I will try that now, once I find it. Thanks.

OK, so I went back to MIUI, installed the siyah kernel beforehand, and it's still the same problem. Also, if I type in any of the "secret codes" and hit dial it says:
"USSD code dial..." then goes straight to "Connection problem or invalid MMI code"
Also, calls still work, so it's definitely just data that's broken right now...

Kernel is NOT repeat NOT baseband .
Baseband= MODEM
CSC = Country specific and network codes .Or set network APN manually .
Modem and CSC for your region should be found and flashed or flash full stock correct region firmware .

Funny story... My APN reset after the rom install.... once I reset the apn settings everything worked. xD

[Q] ParanoidAndroid (and other) JB ROMs - Can't get mobile network to work

I can't post to the dev forum, so maybe someone over here can help:
I tried the PA ROM, because I really love the hybrid mode. The ROM has worked fine and looks great, but whatever version I flash, the mobile network, both data and phone, simply doesn't work.
It briefly connects to my provider (drei.at) and immediately disconnects, no matter whether I have data connection enabled or not.
Have tried this with all available versions of PA and did the usual routine: wipe, format system, wipe data. I even went totally back to a stock ROM, tried various modems, the current one being XXDLH9, which works just fine on [email protected] 0.6 ROM.
Had the same problem with Omega, FoxHound, and god knows what other ROMs I tried. No matter what, the only JB ROM actually working is [email protected] 0.6, that's it.
Is this a known phenomenon or have I overlooked something obvious?
The phone used to be a branded and simlocked Austrian T-Mobile, but ever since it has been debranded and SIM unlocked.
Any ideas?
All i can suggest is your apn settings?
Can try Offline SIM APN Database (get on Google Play) to insert the correct apn settings.

Thank you for the suggestion. The APN settings on a fresh install, all wiped, are correct and the same as in a working setup.
Any other ideas? Am I really the only one with that problem?
Modem tried APN correct .
Suggest next step is factory reset ..
Step after that is to install an official stock rom .
Others who may have a problem post in the roms thread .

Did a factory reset, totally clean install with everything wiped.
Also, did a clean wipe and installed official stock ROM. Lost root, started from scratch and still didn't work.
I'd love to post in the ROM forums, but haven't yet posted my mandatory 10 postings.. Maybe this thread helps me to reach that limit

No, that's not what I said. Stock ROMs work just fine; I actually just flashed the latest leak (DLI5) and had no problems with the network. The problem hasn't changed, so it's what I wrote in the OP: Only JB to work ist latest leak and [email protected] 0.6. All others can be installed but have not network connection other than WiFi.

Thanks for trying to help.
Yes, I have been playing around with all kinds of basebands, trying to flash modems etc. but that does not seem to be the reason for it. I have had different modems working and the very same modems simply did not work with PA at all. Best example ist yesterday's leak DLI5 which I flashed and had a virgin like system working just fine with my network. I then flashed the PA ROM, which then had the same baseband as the latest stock ROM, but, alas, same story: No network.
The weird thing is the brief connect it always shows in the status bar. It lasts roughly 4-5 seconds and then disconnects again, only showing the empty network status display.
It really sucks, because I find the idea of hybrid ROMs really appealing, in fact, this seems to me as a truly superior way of making use of the 720p display.
Need to try logcat next to see whether the connect/disconnect somehow can be monitored from there. Will report on that.

I just installed ParanoidAndroid. I'm kind of a noob to all of this.
I understand some, but not all.
My mobile networks are not working.
I don't get any notification at the top of the screen either saying I'm on a mobile network.
I've messed around with the APN settings. It seems that every now and then it'll connect for a brief moment, but I can't really do anything unless I'm connected to WiFi.
Any help would be appreciated.
I came from a stock phone rooted.
Installed this and now I'm here.
Please HELP!!

[Q] [HELP]Urgent Network problems!

Hey there!
Before anyone asks, I have done the following.
Searched on google/XDA for solutions
Flashed different ROM's
Changed Kernels
Wiped all cache
Did factory Reset
I am currently having bad network problems with my phone.
I am running JellyBam 6.7.0 with default kernel.
Baseband: XXLQ6
Problem
I constently get No Service or "Emergency Calls only" in areas that I've never had emergency calls in. I am not aware of my old modem or RIL, and so am completely lost of what to go from here as I haven't found posts that could help my issue.
When I reboot my phone, turn airplane mode on, or just randomly it will go into the stage above, to where it will stay without signal for 10 minutes up to days (I've had it go for 2 days with no signal). When I try to search for networks (In places where there is 100% a network) it will say "error searching for network".
I have no idea what to do, and am rather scared. There have been 2 emergency situations to where I needed a phone, and yet mine had no signal.
My second question, is if I manage to get it back to stock ICS (4.0.4) and do all the updates through KIES, will I get the original modem + RIL back as well as the ROM? Or will I still need to flash that myself.
TLDR: If I reset it back completely to stock ICS, will everything that I have done (root, flash modems, flash kernels etc...) be erased.
Thanks so much for reading, I've got so much stress rigt now.
Are you getting no service all the time or only intermittently ? Also, check your IMEI in settings/about phone to see if it's the generic one (0049.....), whatever you do tho don't post your actual IMEI here. Just a yes/know answer to the 'is it the generic one' question will do.
If it's a constant thing, call your carrier to check if it's been IMEI blocked. If it's intermittent, flash a stock ICS rom as you'd suggested. You'll end up with whatever modem/baseband is attached to the rom you flash, and yes, you'll lose root & the kernel you're currently running will be replaced by the stock kernel in the rom you flash.

Yes it's only intermittent, so not a problem with the IMEI.
So if I find, and download stock ICS to bring it to factory it should be fine? If I were to, let's say, flash the ICS onto the phone, is there any way to keep the RIL+ Baseband and flash back JB? Or when flashing JB, will it replace whatever RIL+Baseband is attached with the ROM.
Also, thanks for the quick reply. I was expecting days for a response.
Forget about JB/custom roms/anything else until or unless you get your phone working normally again. Flash an ICS stock rom for your region.
And forget about the current RIL/baseband. It sounds like it may well be the cause of the problems you're having; quite possible if you've been mucking around with different RIL's in particular. Pretty sure I said in my PP that you'll end up with whatever baseband is lumped in with the stock rom you flash.
Actually, you might want to stick with a stock rom specific to your carrier if there is one, at least that way you know the modem/baseband will more than likely have been tested by your carrier & is likely to work well with it unless there are other issues (carrier side connectivity issues or other problems with your phone).
As to whether doing this will fix your issues, no idea. At the moment, and in the absence of any clue as to what's causing your issues, it's the best option you've got. If it doesn't fix the problems, then it's probably a carrier-side issue (possible given it only happens at certain times/in certain locations) or a physical problem with the phone (less likely).

I'm having problems to what official ROM to use from the list.
The only one on the list is Optus, but my phone is with virgin (on the optus network) should that be fine?
The rom is I9100XWLP8
Once again many thanks! I'll update you with the progress.
Yep. Flash the Optus rom given you're effectively using their network & see what happens.

Just downloaded it (Hotfile takes forever) and flashed through odin.
Worked fine after a factory reset. However, Kies won't update my phone.
Network seems to running smooth, so we'll see how it goes. The more things I do, I guess the more things I can rule out.
EDIT:
I updated the phone, and I get the message "Unfortunately, Application installer has stopped". What am I supposed to do?

That didn't work.
Anyhow, I managed to track down a 4.0.4 variant of the ROM I was using, and made sure the CSC, PDA and Baseband all matched up with what Kies wanted, and flashed it. I think the error occured I was trying to update a ROM with the wrong CSC and Baseband to one with the correct ones and Kies didn't like that.

Have you tried restoring a nandroid? I'm also on PAC atm, and haven't had any issues with signal.
Else, try a clean reflash of the ROM.

It worked well before. I don't have any previous backups. Yes i tired re-flash as well. Any other solution ?
Suddenly i noticed network is connected and received a SMS. But when i try to take a call it went back to "No Service".
It could be because of incompatible RIL and baseband. Did you happen to change these recently by any chance?
Don't flash any ril if you're on 4.2. Ril is only ok if you're on stock.
What you can try is to flash the stock ROM for your country /carrier. See if the problem persists .
And just a word of advice, always have a backup ready to go.

Flashed official firmware with Odin. But problem still exists. I noticed strange thing. One of my SIM cards working on it. But 2G network. Sometimes shifts to 3G but can't hold also signal strength is low. When i put other SIM it says Not registered on network (cant manually register even)
Did you definitely flash the firmware released for your carrier & region? Sounds to me like you may have flashed firmware intended for another carrier or region.
Try flashing a few modems. Look at which modems your carrier released for your region, start with those. Then, move onto o re her local carriers etc. If you still don't have any luck, go all our and flash whatever modem you can get your hands on (make sure it's compatible first obviously).
It may sound like a lot of work, but unfortunately there's no quick fix for something like this if flashing stock didn't work.
Oh wait. If you did actually flash a different stock rom, flash the correct one first. If you did get the right one first off, start flashing modems.

Ya. I flashed correct firmware. I'll try some more custom ROMS as well. With this ROM i can get 3G and 2G networks. Data also working. But signal is low. You think its a modem issue ?

[Q] Very Slow Mobile Network, Kinda Strange.

Hello everyone, first of all I should post this to Android Development section but since system tells me I do not have 10 posts, I thought I can post this here.
Well basically I was using Disaster ROM for my SGS2 (International) (I'm in Turkey), and I wanted to use Biftor Rom which was actually KitKat and I didn't know that I should install CM 10.2 or newer first to install other KitKat Roms. So I actually softbricked my phone I was only able to go into download mode. So I flashed my phone with stock 4.0.3 using Odin. But I realised that my mobile network was actually slow as hell. Sometime it can't even connect. But I was like "Oh anyways, it will go away if I flash custom rom". But it didn't. I checked my IMEI and it was there, valid. I flashed my phone 4 or 5 times more with different ROMs. But no luck.
Then I heard an app called GetRIL, because someone told me that my baseband/modem thing might be corrupted. When I opened the app I saw that it says "Unknown RIL". So what should I do? I tried setting APN manually, then automatically by my Vodafone Service. Nothing happened, still same. I do NOT want to send this phone to Samsung Service, what should I do about this situation?
Some Details : My WiFi works very well, I can call other phones, I can send messages, I can recieve calls and messages, Only thing is Mobile Data So Slow and sometimes when I turned data on it says no signal for a while. Help Please !
EDIT: Stock 4.0.3 was only PDA file. It wasn't like 3-4 files to set into Phone section, Pit section... It was only PDA. At the moment I am using BeantStalk Rom 4.4.2 KitKat XXLPS Baseband.
Thanks in advance.
Regards.
If you'd posted this in a development thread, you likely would have copped a slap (and quite rightly). Dev threads are for development stuff, not for n00bs having
problems with connectivity.
It may not even be a phone side issue, it could easily be carrier-side. Having said that, you need to try different modems. Plenty of CWM flashable modem packages on XDA you can try. Start with the modems bundled with stock roms released by your carrier (you can check these at Samfirmware, if you click to download a stock rom, it will tell you the baseband, you can then find CWM versions of these modems on XDA), test, if no better--->>> then try modems bundled with stock roms released by other carriers in your country, test, if no better--->>>then try other modems bundled with stock roms released by other carrier in other countries.
Thanks for the suggestion, today something strange happened and the signal "thing" started working somehow and i can use mobile network, but after phone calls it just disconnects for a while then reconnects again. It doesn't look so annoying so I will deal with it for a while. If it gets so annoying or goes into some crashes and other stuff I can apply what you have suggested.
I read some articles that saying XXLPS Basebands are actually not that well, If I try any other modem/baseband "thing", will it brick or something ? Or can i use 4.1.2 or 4.2.2 modem on KitKat ?

i9300 no service/ no sim card/ no gps fix /efs / IMEI trouble - FIXED

This might help someone having these no service/ no sim card no GPS fix issues with the galaxy SGSIII i9300, that might have to do with efs folder change and IMEI corruption.
Okay so i solved these no service issues and ill share my experience so maybe someone will find it helpful.
So the issue has to do with the famous efs folder conundrum, though tbh im not a developer so i cant say exactly what was the issue or even be a 100% sure it was the efs folder.
So I got me a used malfunctioning i9300 which i then repaired at a lab and proceeded to install a new TW based ROM, my first mistake was not backing up efs folder and creating a nandroid, but i havnt realized that yet. After flashing, I noticed that i have no GPS, but i didnt know if the GPS was working with original firmware because i neglected to check that or back it up, so i decided to put a pin in it for the time being and went on to check out some ROMs.
At first, I flashed couple of JB tw based roms, all was well (except for the gps), then i started to check out some KK roms, those didnt play well with my device, I got no service in every single rom i tried, You name it ive tried it, none fixed the service issue. Moreover i also tried a few JB AOSP based ROMs, among them the 4.3 JB PAC-man ROM, those had the same no service/no sim issues. Meanwhile whenever i un-root and flash with odin back to stock or restore a nandroid i made while on 4.3 foxhound ROM (with service working and a supposedly good copy of the efs folder) service is restored. I would also mention that I had more backups of the efs from the working “foxhound” i made with different tools and when i restored these folders when on a ROM with no service it didnt fix the issue.
Here are the solutions ive encountered and tried that didnt work:
-restoring efs with efs pro, samsung tool, efs backup -restore cmd tool.
-flashing latest firmware and flashing back to KK
-flashing all kinds of modems (those pre efs folder change (XXEMG4) and those after)
-flashing latest TWRP/CWM recovery
-flashing kernels
-trying to edit “nv_data.bin” with hex editor
-some more ways in trying to manipulate the efs folder.
-using samsung service codes on stock, which i found regarding this issue, except from the *#06# code, for imei, pretty much none worked for me.
Its important to mention that when on stock firmware or a JB TW based ROM i would see my baseband version in settings and when I tried the *#06# code for checking my imei it gave me a serial number with many digits that I assumed was indeed my correct IMEI number, and when i was on KK ROMs or non TW JB ROMs i would get the same popup with no numbers and in settings i would see “unknown baseband” .
To add to that, whenever i rooted and installed a KK ROM or a JB non TW ROM and tried to restore efs with efs professional i would get a message the device is not perm rooted (but thats neither here nor there).
This research took me about 5-6 days and the end of which i was ready to give up on having a KK rom or a non TW rom for that matter, NOTHING seemed to fix the problem. I just had some fight in me for one more hopeless attempt. I read somewhere that a flashing of cm 10.1 and then going to settings -> more and there change some network stuff from this to that would help -
(Originally Posted by Goose306 on s3forums.com)
"flash back to another AOSP 4.2 ROM (CM10.1, Liquid, etc.)
Got to Network settings. You need to change Roaming to automatic and CDMA settings to RUIM/SIM (I *think* that is the name of it, I'm actually on TW temporarily as I'm troubleshooting some SDcard issues of my own)
Reboot and you should be back in business. Touchwiz doesn't have a way of changing of those settings which is why ODIN/stock doesn't fix it"
I said what the heck thats simple enough. I flashed CM 10.1.3 for i9300 and went into the settings but the options i read about werent the same as the settings i saw in my case,
so i did move one settings around in the settings-> more section, cant remember what it was and im on a different ROM by now,
it was nothing i knew about anyway (but you should give it a go and have a look, there are few options to choose from so you can eliminate your way to what makes sense).
I then went on to recovery to flash carbon rom 4.4 and to my enormous surprise i had service and connection and to my astonishment i also got back the GPS as a bonus ! yay ! I bet you forgot about that too by now…
This ends on a weird note though, though everything is at working order now and the IMEI number i get is the same as the one i get when on stock rom,
it does not match the number on the back of the phone under the battery. well mehh.. as long is its working.
Hope this helps someone.
You didnt mention that exact step. Changing "something from this to that" doesn't really count as being helpful.
Thanks for the post anyways.

Youre right, i couldnt find the thread that had the suggestion to install the 10.1 cm but my point was it didnt even apply to my situation because the options in "Setting -> more" werent compatible with what was suggested in the thread so i had to improvise and I just changed some setting i cant remember in "Settings -> More" but I realise that it would be more helpfull to say what i changed there exactly, but im not on cm 10.1 anymore and cant see what in there now.. the good news is that there werent many options to change there.
But i did went out and looked for the original comment that made me try this an it says -

Got to Network settings. You need to change Roaming to automatic and CDMA settings to RUIM/SIM (I *think* that is the name of it, I'm actually on TW temporarily as I'm troubleshooting some SDcard issues of my own)
Reboot and you should be back in business. Touchwiz doesn't have a way of changing of those settings which is why ODIN/stock doesn't fix it"
so in my case i didnt see these exact same options so i changed what seemed to me the most related to the issue at hand.
I dont think i had to touch the roaming, again i dont have CM 10.1 installed so i dont recall exactly what were my options.
is it a solution mostly for Qualcomm chipset based I9300 ? someone can say ? European providers use different frequencies I guess hence different chipsets and parameters.

mine is the international version but as i mentioned it didnt work like described but the end result was the same. I f you have the LTE version Im not sure which option youre going to get in CM 10.1 settings -> more , but if youre having trouble with service and GPS and stuff like that i do suggest you try flashing CM 10.1 (compatible with LTE - not sure how it goes with CM and LTE compatibility) and check if you got the same options to make the changes to, if not, try and improvise based on what makes even a little sense, thats what i did.
It might be that the flashing of CM 10.1 itself is what fixes the problem, so if you change nothing it might help still, anyway this is pretty simple and quick to do so better start here than starting with other messier solutions.

I believe I shared every bit of helpful information i can share with you about this issue and my process of handling it in the main message of the thread, Read the entire thing and the comments followed, then follow my suggestion, if you wish to do so.

Thank you, I was suspecting that you have a similar version than me. Well, in desperate cases anything can be tested (But some have told me not to mess with US versions as there is a risk of burning something )
Anyway the last version I could not flash , the CM 10.1 it was ejected with a file error soon despite 3 downlowd.
I will try with another more compatible version with Cyanogen.
Have a nice day

This might help someone having these no service/ no sim card no gps fix issues with the galaxy s3 i9300, that might have to do with efs folder change and IMEI corruption.
Okay so i solved these no service issues and ill share my experience so maybe someone will find it helpful.
So the issue has to do with the famous efs folder conundrum, though tbh im not a developer so i cant say exactly what was the issue or even be a 100% sure it was the efs folder.
So I got me a used malfunctioning i9300 which i then repaired at a lab and proceeded to install a new TW based rom, my first mistake was not backing up efs folder and creating a nandroid, but i havnt realized that yet. After flashing, I noticed that i have no gps, but i didnt know if the gps was working with original firmware because i neglected to check that or back it up, so i decided to put a pin in it for the time being and went on to check out some roms.
At first, I flashed couple of JB tw based roms, all was well (except for the gps), then i started to check out some KK roms, those didnt play well with my device, I got no service in every single rom i tried, You name it ive tried it, none fixed the service issue. Moreover i also tried a few JB AOSP based roms, among them the 4.3 jb pac-man rom, those had the same no service/no sim issues. Meanwhile whenever i un-root and flash with odin back to stock or restore a nandroid i made while on 4.3 foxhound rom (with service working and a supposedly good copy of the efs folder) service is restored. I would also mention that I had more backups of the efs from the working “foxhound” i made with different tools and when i restored these folders when on a rom with no service it didnt fix the issue.
Here are the solutions ive encountered and tried that didnt work:
-restoring efs with efs pro, samsung tool, efs backup -restore cmd tool.
-flashing latest firmware and flashing back to kk
-flashing all kinds of modems (those pre efs folder change (xxemg4) and those after)
-flashing latest twrp/cwm recovery
-flashing kernels
-trying to edit “nv_data.bin” with hex editor
-some more ways in trying to manipulate the efs folder.
-using samsung service codes on stock, which i found regarding this issue, except from the *#06# code, for imei, pretty much none worked for me.
Its important to mention that when on stock firmware or a JB TW based rom i would see my baseband version in settings and when I tried the *#06# code for checking my imei it gave me a serial number with many digits that I assumed was indeed my correct IMEI number, and when i was on kk roms or non tw JB roms i would get the same popup with no numbers and in settings i would see “unknown baseband” .
To add to that, whenever i rooted and installed a kk rom or a jb non tw rom and tried to restore efs with efs professional i would get a message the device is not perm rooted (but thats neither here nor there).
This research took me about 5-6 days and the end of which i was ready to give up on having a KK rom or a non TW rom for that matter, NOTHING seemed to fix the problem. I just had some fight in me for one more hopeless attempt. I read somewhere that a flashing of cm 10.1 and then going to settings -> more and there change some network stuff from this to that would help -

:crying: :crying: :crying: :crying: :crying: Dude!!!!! I understand!!!!
I had a similar experience only I also tried flashing CM 10.1 and it did not work. Although I have another imei, I have all my services running on the Stock 4.3. Now the only problem is that if I change to any other rom, does not connect to the wifi network.
I found something like this: http://forum.xda-developers.com/showthread.php?t=839367&page=4
But neither worked. Yesterday I tried to repartition the phone and almost killed. I spent two weeks looking for a solution, and tried them all, but did not work, I think I will draw on the last and the only thing I think work ... The box.
The octopus box (or similar).
KK roms are beautiful ... but no matter what, I have no wifi in another rom than the stock 4.3 lol.
Thank you for your contribution! as you say: I hope you serve someone else.

yeah thats some BS those signal and issues on the i9300.. they really did a number on that one.
sorry my thing didnt help, i too tried everything and got nothing.
Maybe try flashing CM 10.1.3 and changing those options in settings-> more, Might be that just flashing CM 10.1 wont do it, I did change something ther but cant remember what it was, i wrote in my post what someone else had ther in the options but i had different ones but I still changed one option there ( what i thought might be connected to the issue ).
anyway dude i feel you its crying shame whole thing, and so many are posting about these issues all the time, im kinda hating on samsung cause they always seem to mess up like that.
Hope you solve this somehow..
