[SOLVED] [HELP] No Mobile Data in SGS2 - Galaxy S II Q&A, Help & Troubleshooting

Hello folks, this is my first post Hope to have a solution for my M250S converted to Galaxy S2 which I'm having a problem with.
I'll get to the point straight.
The problem that I'm with S2 is that I'm not able to use mobile data. Even though I've enabled mobile data from settings, No mobile data icon is shown in status bar. I've set up APN settings correctly as well. Did try with different network SIM with correct APN settings. But no luck. I'm talking about either EDGE, HSPA or 3G icon in the status bar (like in attachment below).
But internet via WiFi works fine. Tried flashing a new stock ROM, custom ROM, wiping out cache, factory resetting and turning on "WCDMA only" as well :crying:
Could this be a hardware fault? Or firmware issue (like csc or modem)?
Note : On the first day I purchased the phone, mobile data worked (and it was already converted to i9100). But backside of the phone near camera got overheated. Then I turned mobile data off and switched to wifi. Afterwards I can't remember that I could use mobile data.

Thanks for the reply. I searched that thread. Someone had mentioned to flash the modem via CWM. So I did flash the correct modem after downloading from here.

Yes, I flashed the Jellybean stock ROM 4.1.2 (XWLSN) and hoped to get a solution for the problem. But no luck.

So you can make calls and no data. Just try a restore of your efs. Its a very bad file that can be curupted so easy. Most will have no call but data. See were im coming from on this. Worth a try.

I heard in some countries, even the generic Samsung IMEI may work for calls or Internet!
@OP: have u verified that ur IMEI number is correct and the same as that below ur battery? (Do not post the IMEI here)

Maybe you should try another I9100 firmware.

Thanks man. Flashed i9100 4.0.4 ICS stock ROM and it works :good: I think it's a problem with 4.1.2 JB stock ROM and 4.1.2 based custom ROMs
Wonder why it's only my M250S which has faced this problem

[Q] Samsung galaxy2 i9100p itself off

Hello I'm from Spain and I want to ask if anyone knows what happens with samsung galaxy s2 i9100p? Many Vodafone customers have problems with this phone, it turns itself off and have removed the battery to start .Thanks.
I'm in the UK on Vodafone using the i9100p model. Never had the problem you mention.
Sent from my GT-I9100 using xda app-developers app
All models purchased since September with ICS 4.0.3 black screen sometimes freezes and no longer responds to commands without removing the battery. Stops but not actually answer. Not yet known if there is a problem software or hardware and many speak it may be a hardware error.I do not know what to say.In England you heard of it?
Cant speak for everyone but..
Had mine for over a year. Have run gingerbread, ICS and jelly bean based stock and custom ROMs - no issue at all.

No because still learning about my new device I came from S5830 threads, but there are some diferences... What about 4.1.2.? only exist TIM's branded official rom for I9100P currently
4.0.3 XXLPP from Vodafone Spain, my phone is still locked at the moment, there is a 4.0.4. Vodafone's Spain rom but not exist a safe kernel as PhilZ to this rom so I don't want to update because I use NFC with my friends

Try updating to JB and see.
If it still persists, it could be a hardware issue.

I've only suffered 2 random shutdowns in 2 months... I think is a software bug, because all works fine :S maybe deepsleep trouble¿?
It's safe update I9100P's device with a I9100 rom via Odin?¿ umm what about the misteryous triangle ¿? LOL, It only appear when you flash via stock recovery, isn't it?

Both I9100 and I9100P have identical hardwares except for the NFC Chip. So, it should be safe to flash an I9100 rom. But you will lose NFC capability. To restore NFC, you will have to flash a patch.
The yellow triangle appears when you flash custom kernels or roms via Odin. It disappears when you flash stock roms.

And, flashing original firmwares increase flash's counter?
About JB and ICS, how much ram normally JB used? and how about battery duration?

Flashing original firmware for ur device doesn't increase the binary counter.
Free RAM and battery usage depends on the ROM configuration and the apps installed. I get a full day on moderate usage, while heavy use reduces it to around 7 hrs.. And I usually have 550-650MB RAM usage.

In a way, you could say JB sucks. But I wouldn't blame it, because JB has additional features that require more RAM.

[Q] Anyone Having slow WIFI connection Speed on Jelly bean 4.1.2

Hi all,
Anyone having this Wifi speed problem on SGS2 i9100G with Stock Jelly bean 4.1.2?
i download the firmware from Sammobile and flashed to my phone via odin. I did wipe out data before flashing.
This is my phone version
PDA: I9100GXXLSR
Phone: I9100GXXLSP
CSC : I9100GATOLS1
I tested with my phone Speedtest apps Download speed :20kbps
I tried with my friends SGS2 on ICS and getting : 700kbps +
Both tested with the same WIFI network and one to one connection.
Any fix or guide to solve this??
thanks~
Change/Update ur firmware.
Seems like there is a problem in kernel with wife driver.
And I won't think that it's always like this on Jellybean, because it's first time I heard about this.
So maybe a firmware fold or a bad flash.
Much success

You can flash kernel alone, instead of flashing the entire rom.
Might work.. might not..
Be careful what u flash. Only flash stuff meant for I9100G.

[Q] [SOLVED] Galaxy stuck on logo screen

- SOLVED - (Thanks to immortalneo )
Hello, noob here D:
Here's the story.. I recently got a Galaxy S2 i9100. It's updated to the 4.1.2 thingy.
Tried to root it, used odin and CF-ROOT v5.5 in the process. Odin said it was OK but I got stuck on the yellow triangle.
Found a guide, guide said to install Stock Rom.. so I did. (Stock rom is I9100XWLPU_I9100XXLQ6_I9100XEZLP3_HOME.tar )
Now there's no yellow triangle but it's stuck on the flashy S screen.
I never had a smartphone, and I don't understand most of the words people use here (mainly that 'flash it' thing xD )
I tried to look for a post or anything to solve this but kinda failed..
Help?
What you have is called a 'bootloop' mate.. it can be sorted out.
Which android version do u have now? Its 4.0.4 right? 4.0.4 is subject to risk of eMMC Brickbug.
So, I suggest you download another stock firmware (other than 4.0.4) and flash it via Odin.

U mentioned 4.1.2. You also mentioned flashing stock firmware XWLPU, which is 4.0.4.
Yes, simply download a 4.1.2 firmware for ur region from sammobile.com and flash via Odin.
If it still bootloops, boot to recovery and do a factory reset.

It is upto you. Flashing or rooting always carries a small risk of messing up ur device. That's what makes it so much exciting!
You can however make backups of ur apps and data before attempting anything. Or if u root ur phone, u can make a nandroid backup too.
