[Q] Galaxy S2 not Working. Help Needed! :( - Galaxy S II Q&A, Help & Troubleshooting

Guys...
i always read on xda about stuff on how to root s2 and all...
an everything was going well for me...
the last rom i flashed was Villainrom 2.4.2 and Ninphetamine kernel 2.0.5
Everything was going well for a week or so..
but all of a sudden a call got dropped today...
and after that i lost all service to my network...
it was appearing like the sim card was not inserted (there is a icon like no-parking on the status bar)
at first i just switched to flight mode and back on...no change
and then i rebooted the phone...still the same
i even reflashed the rom and also the stock rom just to see what the problem might be...
but still it was the same...everything other than the sim was functional...
then after searching and reading through xda...i decided to check my imei and baseband...
they both are UNKNOWN
the guys on the forum were talking abt 'efs' folder and stuff...
unfortunately stupid me did not back-up that folder
I purchased this phone 4rm UK guys...n i live in Sri Lanka (which is quite a long way)...
got the phone with a great difficulty...
its kinda impossible for me to send it back...
i got it the hard way
now i feel so bad....
am stranded guys...
please do help me out....
btw i registered just now because of this problem
help me out guys...
please

please help me out guys...
i have placed my faith in u all only

Not sure if this will help. It seems that if you use a back up from another phone and flash it over to yours (might need to be on the same network *shrugs*) it works *maybe* there is a dedicated thread. The OP fixed his problem and stated the solution as well.
Hope it helps.
Cheers.

Just copying efs folder as backup can't solve that. I suggest to flash back to stock rom and bring it to service center and lie about what happened. Just say you were on a call and all of a suden that happened. Don't mention you flashed and rooted etc.

My galaxy s2 with no imei and no baseband ???

How can i solve this problem
with this problem: Imei : unknown baseband : unknown
after my phone fall this problem appear how can i solve this please i need you (giant)
Pleaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaase
It may be becruse of your rom
I am having this issue too, I have tried several roms to but all have this issue. I am now on the stock o2 rom and the problem is still there, anyone else had this?
Thanks
My P500 doesn't display an IME either after installing Cyanogenmod... at least on the P500 it's a known issue, but beyond that you may have more luck in the galaxy forums, as there are more people there with the same device.
Just ask the moderator (PM) to move it.

Hey brother can you tell me how to solve this problem ?
I have same problem here cant call and text
Try this:

buddy tell how to fix this!
Imei no base band eror solved
I have cross the same issue before... But my s2 working fine..
This error occurs sometime when flashing a new ROM. So, first of all you should backup your EFS-map. But for that it is too late hehe.
Reflashing works sometimes. I know that when installing a MIUI ROM you should also flash a zip-file that backups your imei, otherwise you'll have no carier. Maybe you should flash that EFS-backup zip-file and then reflash a ROM?
Hope is works for you buddy, goodluck.
you get it from Android market or new Android market, the only thing is your phone must have root, there is efs file and another file, not to sure but I flashed my Samsung galaxy back to Android 2.3.5 with a rom I got from Xda and now I dont have super user and the only way to use HC-KTool is if your phone has root, super user permissions, you can also try KTool is the same thing on the Android Market, you can also get Root explorer, rom manager they both have efs files but you must have root, so simple download new Android Market from 4shared.com then download HC-KTool or KTool from the new Android Market, good luck!
I am facing the same problem of unknown baseband version and IMIE no. Although i didn't do anything weird with my sgs2. I have been using it four 5 months now and its stock (Not rooted no any roms installed). Just today i faced this problem after i was changing between some sim cards. I tried factory reset a no. of times but it didn't help. Kindly help since i don't want to end up with just an "expensive media player" like someone quoted here! In dire state now

No service/network after Root + Custom Rom Install - PLEASE HELP ME.

I have an S3 i9305 4g lte version, on orange network uk. I rooted the phone using CWM. Then installed the Panorama ROM, using the guide on here. And yes i have used the search function, followed pretty much every guide there is. Still no solution. Im beginning to think my phone will forever be caught up with this problem
on top of there being no service. The phone itself has started to randomly turn off, and also lags!
I regret rooting lol just wasn't meant to be.
Can anyone help me? Literally, I would be so grateful if someone can actually help me fix this problem. I basically just want my network service back, regardless of unrooting or not.
Thanks a million in advance!

Don't let one unsuitable ROM tarnish your experience Try flashing a different modem.http://forum.xda-developers.com/showthread.php?t=1740061
Also, if you're unhappy with the ROM, flash another one. Plenty of good roms out there.

Try different ones to see which one works best for you. Also search those threads for your network/region to see what other people are using.
Does your IMEI match the one under the battery?
Do you have an EFS backup?
Also, this is a section for the i9300

Look dude, the simple matter of the fact is that you're not special. Other people have had 100% exactly same "problem" as you and have solved easily by reading the topics that have already been created about this matter.
We have various topics on unlocking sim after flashing JB so go read and learn.
creating duplicate topics and labeling it as "URGENT!!!!" doesn't help you it just irritates people into not wanting to reply or help you.

If i understand right what are u asking for is an UNLOCK code for the phone because it is not booting up at all and u can't even get to sim unlocking screen where u have to input ur PIN ? Is that correct?
If yes, i've had same problem on my old GalaxyS, im not sure if it will work on S2 but here is what i did.
1. I've typed in random letters, numbers few times
2 Phone said if i'll put in another wrong code it will format my SD card.
3 I did that anyway.
4. Phone was unlocked and SD cart NOT formatted.
If u can go to recovery mode u can try to mount usb storage and make a backup of ur SD card.
I hope it helps.

No... Its not the case. I come across that screen but i dont have any key to put in so i just dismiss the msj... And the phone's working but the sim is not registered... I was thinking if it is to do anything with the country i am living in.??? Any ideas?
I suppose ur not asked about PIN code, so there is no sim card inserted or phone is not recognizing its presence. Maybe its silly but pull it out and push back in. If there is no contact problem and u have tried various roms and kernels then i would start suspecting hardware issue.
Post a screen shot.
And it better not be a SIM PIN code.

Hi guys,
i'm an italian boy that has a galaxy s3 with a problem: i can't call or send messages because on the screen there is "not registered on network"
i do nothing, my phone is genuine...i didn't try to change rom or to do something...the problem is appared suddenly.
How can i fix the problem? imei code is intact and my telephone operator didn't block my phone or imei...
i know that in this forum there are some topics about this problem, but it is very difficult for me find them...
help me please...i haven't assistance...

Look for the serial, if it starts with 00000 or something like that, you nees to use Ariza Patch.

...my wife had this problem last week. Phone was saying that it was not registered on Network. Looked around on the net, checked settings on phone and found that if you turn the phone off for a few minutes and back on, it re-registered to the network. Very basic, don't know why it did it, but it's now OK

This is the problem: imei code is ok but there is "not registered on network"
About the other solution, i'm going to try it but i don't think it will work for me..

Hey man I read that it could have sumpin 2 do wit type of modem mg2 or mg4 try searching about which versions of firmware have which on mop

i got it fixed but i will tell u how it happened to me so u can connect the dots with ur problems ,,
i was on omega rom v49 but i wanted to return to stock and un root (4.1.2) to do some things i had a problem while restoring the cable disconnected but i started the process again and everything worked fine except for the network i couldn't call and when someone calls me it gives him that my phone is ringing and i got nothing (be aware u may have got many calls)
i tried some videos from the youtube and tried ariza patch (i dont no if i did it right or not i choose patch 5 and rebooted but nothing worked ) and flashed some modems but nothing

anyways here is the theory .. (what if we went way back to the first omega rom n kept upgrading till the latest one ... could it be the solution ... ??? LOOL its goofy but u know when ur desperate u think about some crazy stuff... so thats what i thought about ... coz there r many users who flashed older roms n it worked for them ... im just saying ... lets try to track our histories of our roms n c what happens ... thank u ..
