Help me fix my data connection - Galaxy S II Q&A, Help & Troubleshooting

So here is the problem, i flashed the jeallybean leak rom. Then decided to go back to 10.1 so i fully wiped and flashed 10.1 but since i have done so, i have no data connection on my phone. I have the correct APN but it doesn't try to connect.
Did the leaked jeallybean rom mess up the phone? I notice now the serial number is listed as "unknown" could this prevent the phone from connecting ?
I tested my sim in another phone and it was fine, so just no data on my phone regardless of what sim/apn i use. So something is wrong

I had some data problems after trying the jb leak. I just decided to go for a clean install, flashed a stock 4.0.3 rom, made all wipes and reflashed a custom rom.

If I flash CM9, and then restore my current CM 10.1 back over it, think it would work? I don't want to be stuck on CM9 but the jeallybean leak really botched my phone somehow

If you already have a backup of previous 10.1 just restore it now, no need to flash CM9.
Also try flashing new modem.

Please someone correct me if I'm wrong, but I think the jb leak has some kind of different layout with regards to using the preload folder and doesn't like you changing modems/rils etc. I'd had enough trying to sort it out so by flashing a stock rom I knew the preload/modem etc would be sorted (at the same time I backed up by the important data from my internal and external sds and formatted them to clear out some of the crap I had lying about from all my old custom roms.) My phone is working better than ever now

Well, I flashed a clean CM9 and leaving the same modem and APN and the data worked. Nothing is different in CM10.1 with my settings , so it has to be something going on with CM10.1 . I installed it clean after i wiped the jeallybean leak

U must change your modem to ur country modem

[Q] Phone freezing after updating ROM

I've already asked in the relevant ROM thread but thought I'd try here in case anyone else has had a similar issue.
I'm currently running Westcrip ICS 9.4 and tried to update to latest version but phone freezes a few seconds after booting (have to restart/battery pull)
I've tried wiping data/cache/dalvik/fix permissions but get exactly the same problem.
I've tried flashing stock GB through odin which works ok and then flashing again but get exactly the same problem.
I've tried flashing bezkes aokp but get exactly the same problem.
Thankfully my 9.4 backup restores OK and runs without any freezes.
The only thing I think it might be is something dodgy/corrupt on my internal memory or SD card. Is it safe to wipe these? I dont want to move my backup as I've had MD5 problems when trying to restore in the past.
Does anyone have any other ideas? I've looked around on the forum/google but can't find anyone else reporting the same problem.
This is driving me mad!! Am I missing something?
No ideas?
Ill try again after clearing internal storage. Can someone recommend the best way to do this please?
I should have said that i get the freeze problems with no non rom apps installed...

Well you are using buggy beta ICS base .
As you can flash and use a stock rom then the problem is the rom you are flashing .
Possible corrupt download .

Thanks for the reply. I tried downloading again but still have the same problem with resurrection and bezke so will try loading a stock ics base through odin when i get home tonight. Do you think my 9.4 resurrection base could be the problem? I read that on earlier ics roms that you should flash stock ics first?

No idea really but how can you flash a stock ICS its not released .

I've been using Bezke's AOKP for 5 days now, without any problem, so the problem is definitely not in his ROM.
When you flash it, try the following:
after wiping data, cache and dalvik, go to mounts and storage and hit format system. It could do the trick maybe...

Arghh!!! Tried this and thought it had solved the problem. I've managed to install the new paradoxx rom now and even reinstall my apps and set up email account, but phone eventually freezes again. I've even started getting random freezes in CWM now! What I cant understand is why my phone is still rock solid running my westcrip 9.4 backup??
I think I might have flashed my phone to an early grave!!
That is really strange. Sorry that formatting system didn't help

[Q] Really Need Some Help Guys

Hey,
I've had a really big problem with Siyah Kernel V3.1 rc6, i flashed it not long ago because i was going to go from CheckROM v6 to HyDrOG3N 18/04, but i didn't get hard bricked by the Kernel as people have been experiencing, I got a Soft Brick, so I went back into CWM and i couldn't flash anything, anything i tried to flash anything it would give me the error "failed ro:getprop I9100" or something along the lines of that, so i started messing around, hoping for anything to work, and creating a second ROM through the dualboot settings and deleting it somehow worked, but now I can't connect to my service provider (T-Mobile UK) regardless of what i have flashed on my phone, this is a really big problem for me as this phone is my day to day phone and i dont have a backup at all, if anybody has any suggestions at all as to what it could be and how I can combat this as soon as possible, I would be really appreciative
TIA Guys

You could purchase mobile odin off the market, and data limit allowing, download the cm9 ressurection edition (ie cm9 flashable through odin). that would be my best advice
^ cause you wouldn't need a pc then

[Q] WiFi not working on JB ROMS

Just got a GSIII today and have been trying some JB ROMS out, but so far I have not been able to get WiFi working at all with any of them.
I have tried Vanilla RootBox, LiquidJB and SuperNexus but whilst I can see my WiFi AP on all of them and can enter my password all I get is the "Connecting..." message for ages before it gives up?
WiFi works fine on the stock ROM, and there are no obvious settings on the WiFi router itself which would be causing this.
Any advice appreciated!

Thanks, I just spotted a couple of threads mentioning this.
Couple of questions, when you say flash back to stock does that mean through CWM Recovery, or some other way? Does it have to be a straight flash to a downloaded stock ROM or am I able to just "restore" the backup I made?
Thanks again!

Cool, so I've got Odin (I believe that's what I used to root the phone?) Is there a specific .zip I need to flash back to? Also do I need to boot back in to the stock ROM or just stick JB straight back on again?
Please note, when you have flashed back to ics you need to then set up phone and connect to Wi-Fi once, then proceed to flash jb

Excellent. Do I need to download a specific "Stock ICS" ROM to do this? Any pointers as to where I can find this?
Thanks for the help people
I seem to remember I just flashed an old wannamlite Rom in cwm
http://forum.xda-developers.com/showthread.php?t=1646610
These ones. (4.0.4)
Or try http://fus.nanzen.se/
This is if you want to find the original firmware your phone came with.
I'm still not having much luck with this.
Should I be wiping before I flash back to ICS, and then again before back to JB?
I think a wipe before flashing ICS is enough.
But watch the youtube video on the first post on :
http://forum.xda-developers.com/showthread.php?t=1646610
It pretty much explains every part of returning to stock ICS. From there it is just reflashing JB with odin and wifi should work.
Hmm, still not having much luck. I've installed my JB ROM, wiped, gone back to stock ICS using the ROM from the link provided above in ODNI.
But now when I try to reboot in to recovery to re-flash my JB ROM I seem to get a different version of recovery from what I had before and it fails during verification when I try to flash the .zip.
Any advice welcome!
I'm having the same problem here.
BUT, even flasing stock ICS and flasing a custom JB ROM after that does not solve the issue.
Here is what I did in what order. Maybe I'm missing some essential point or whatever:
- full wipe in cwm recovery
- flash stock ICS via Odin (I9300XXBLH3_I9300DBTBLH4_I9300XXLH1_HOME.tar)
- reboot and test WiFi. WiFi works fine! Firmware is 4.0.4
- flash CF-Root-SGS3-v6.4 to gain root again
- boot into CWM Recovery, format /preload (to get rid of apps installing themselves on boot)
- another full wipe
- install zip from sdcard (tried AOKP JB build 4 for i9300 and ParanoidAndroid v2.22)
same old ****! WiFi not conecting!
I would apeciatie any help to solve this problem for me. Aparently reverting to stock ICS has solved this for others but I dont get what I'm donig wrong her...
try some router side adjustments

you need to root again flashing 'CF-Root' via Odin to get CWM recovery. I guess.

that does not seem right. My phone connects just fine with any ICS based ROM. It even conects with JB ROM Android Revolution HD.

Okay so I Re-rooted with CF-Root through ODIN and have got CWM recover back, but now when I re-flash JB I still get the same problems, try to connect to WiFi and it just sits there saying "Connecting..." and then gives up!
Is there a specific set of steps for doing this? I connected to WiFi whilst back on the Stock ICS ROM (LG8) and that worked fine, I have tried various combinations of wiping/not wiping at each stage in between JB->ICS->JB with no luck. Do I need a particular Stock ROM to go back to, do I have to use a specific version of ODIN/CF-Root/CWM?
Very annoying as everything else about the Jelly Bean ROMS seems perfect!
Has anyone worked out why JB ROMS are doing this?
I have the same problem
It seems to work for some people to go back to ICS and then flash JB ROMs, but somehow it does not work for us..
I'm trying an old stock ICS now and the will flash cm10. lets see if that helps
I've downloaded a selection of stock and custom ICS roms to try with the process, hopefully something will do the trick!
Also I don't think changing router settings can have anything to do with this as it works fine for every other device I own, including a different handset running JB. However out of curiosity I spent last night playing with all the settings to see if anything would help. It didn't
U said u flashed back to stock.... In that case u lost cwm then ur gonna hafto re flash cwm

just re- flash stock (yes stock OFFICIAL) look on the on the general thread. and once done, try boot into recovery and will most likely get into it. Then wipe data (formats SD card) and wipe cache, then reboot and all will be fine. I always re-flash stock TWICE when coming from AOSP/AOKP/CM10 and always wipe data.

[Q] Weird issues Cm11 / Stock

Hi there,
My SIII i9300 has been rooted and flashed with CM from CM 10.x to 11.x. Hoewever, recently it started to not give any audio during voice calls trough the normal mic. Speakers do work.
So, i've tried reflashing, clearing cache / dalvik etc. To no avail.
I then tried stock rom and for some reason this seems to do the trick.
As i'm not really a great fan of the Samsung bloatware and the 'awesome' skin overlay of samsung i would like to fix this issue.
I also tried some different roms to no avail. ( Also, i installed cm 10.2 because that used to be working fine)
I then tried installing different modems via CWM and ODIN. (BUELK1) and (CEEL1). It's a dutch phone on vodafone.
Any information would be greatly appreciated!
Btw, currently i'm running CM 11 nightly see below. Android 4.4.2
My baceband is currently i9300CEELL1
Kernel version 3.0.64-CM-gb1c5066
CM 11-20140228
greetinges, Volc
Try installing the ROM before wiping everything, including System ( data is recommended, as long as you don't have something important not backed up). And with 4.4 try to use MK6 modem or higher.

Hi Andry!
Many thanks for your reply. So I should turn back stock, install cm and that mk6 without wiping? I'm not sure if cm will install without the wipe..
The mk6 modem, do you have any clue where to search it?

I thought you found the modems on www.boeffla-kernel.de . You can find them in the Download section. Also, if you are on CM11 (or any other ROM actually), you should download the ROM tog want to flash on your external SD Card, reboot into recovery, wipe system, cache, dalvik cache and data, flash the ROM, reboot system and use it for a few moments at least ( I would recommend you do that so that you won't get bootloop). Then, reboot into download mode, connect phone to Odin and flash the ROM. I would recommend wipe shading cache and dalvik cache, just for a flawless experience.

I saw this phone firsthand. (Hi volcomoo!)
The roms were flashed OK, double triple quadruple wiping probably wont make any difference.
The weird thing is that with CM installed there seems to be a hardware issue, when we flash the phone back to stock, everything works. I guess the developers will say "logcat or it didn't happen"....
