Hi
Recently my S2 just stopped reading my SIM when I was going to call someone. Since then it has refused to read my SIM, or any other SIM for that matter.
To fix this problem I've tried resetting the phone to factory settings (in 3 different ways ( hard-reset.com/samsung-i9100-galaxy-s2-hard-reset.html )) with no luck.
I've also tried installing alternative ROM's, but with the same result.
The phone was already rooted with an insecure kernel when this happened, so warranty is long gone.
Though, one thing I did realize was that even though I did hard-reset the phone several times, some of the settings on the phone remained untouched, like my locking pattern and a few other settings. Does this mean that hard-resetting the phone isn't really an actual hard-reset? If that's so, is there any way to properly 100% reset the phone?
In short; I'm running out of options on how to fix this. I refuse to believe it's hardware related, just because I'm stubborn like that.
Any help would be greatly appreciated (really).

You can refuse to believe in gravity too, but falling from high distances will still hurt.
If you tried more than one SIM in the phone and none work, but those same SIMs work in other phones, than more than likely, it is hardware related.
Did you check you imei?
078gregory brings up a good point. So if it's not missing IMEI info, THEN it's likely hardware.
Isn't it funny how everything suddenly works itself out once you cry out for help?
Today I've been trying around 10 different ROM's on the phone. Custom and stock. As one last attempt I gave a random ICS 4.0.3 march ROM a last try, and guess what. I got the SIM prompt. I can not believe it. So yeah, it's working now. I have no idea what caused it, but I believe the phone was stuck in flight mode somehow, and just needed an extra push to get out.
Either way, it's working like a charm now. Thanks for the replies though.

Hi people. I have the same problem Habitats decribes. Mi s2 is stuck in flightmode and cant get out! i have reset the phone in every kind of way but no succes. Now i read here on this forum that flashing my phone to ICS 4.0.3 can help solve the problem. I'm on 2.3.6 now. This flightmode thing happened al over sudden. I have done nothing strange with the phone. Its not rooted either. I was planning to go to a samsung servicepoint and let them check whats wrong. But now i read this thread and see that i can relate to this problem of Habitats. I think a also will try to flash ICS 4.0.3 and watch what happens. But theres another problem. KIES don't recognize my phone anymore so what can i do? Can someone please help me out? Thanks in advance
I'm having the exact same problem, could you please tell me which rom worked for you Habitats? Thanks in advance!
Update:Last tuesday i went to the vodafone store were they have a samsung service department also. I explained my problem to them but they don't seem to recognize the problem. Although i read that many people here at xda's and over the internet have similar issues with this phone.Strange! So they sent it to the repair centre. Yesterday i could see in the track and trace menu of the repair centre that my fone was ready and send back to the vodafone store. Status: Boardswap. So they swapped the whole board! Didn't know that the problem was that serious! So i hope i can pickup my galaxy s2 soon this coming week!! I can't wait!I'm on my old HTC Touch HD now. Its ok with the windows but on Android....Arggghh!! Whatsapp is a pain and more. Its so laggy!. I will give an update soon again!
I will make this short as possible. My friend has a VZW RAZR, all stock the way it comes from the store, no root, no mods. The past couple weeks he has told me his LTE hasn't been working. He was unable to get the ICS OTA to install, he tried several times. I went to help him Saturday and have been doing some reading and such. It always fails on the install about a third of the way through the progress bar. I learned that holding both volume buttons brings up the text saying what the install process is doing and eventually the error. Sure enough, every time it gets to the LTE part it errors and fails, apparently his LTE just decided to kill itself a few weeks ago. Even a factory reset didn't solve anything. Anyways I plan to go help him later this evening and I was hoping to get some directing how I can manually install the update or what it is I need to do to fix the LTE error and complete the OTA. Any help is much appreciated!!
EDIT: Whoops, forgot to mention I know about this thread and this is what I plan to try if nothing else. I just couldn't find anything in the forums about LTE crapping out for no reason. Anybody think this is the method I should try or have a different suggestion?
hey guys this is my first thread seen as i cannot find any answers. in a nutshell, i have an s3 that is rooted purely to unlock it. im not too fussed as yet to get the fancy capabilitys in full throttle on a rooted device until i solve one problem.. just hear me out. if you need specifics on my phones firmware ect ask away and ill do my best. but all i can say is this..
i have had a galaxy s3 for a week now. the first thing i did was root it as it was locked. as far as i know i did it right, since it did unlock it and add the supersu icon and CWM icon. as for now i dont want to start messing with stuff like that until i know what im doing. and honestly i only just managed to root the thing after failing the first time. so my real problem so far is something i have heard of with no solution. the wifi and lock screen crash. ive sussed out that for every time i leave the house and go to work (that doesnt have wifi) and my wifi is left switched on, my lockscreen just will not let me in my phone with out me taking the battery out and turning the wifi off manually.
i need help. big help. i need to know waht im doing and doing wrong. i need a fix. a custom firmware a custom rom. what ever it is. i would be so greatful not to have this bug. and ill be honest. it took me 2 days to work it out. i work 9 hours a day and taking my battery 10 times and hour.. yeah.. please help me guys id be so appreciative of it.
thanks. danny.
As a last resort you could try a factory reset. You will lose all your data though and have to set things up from scratch.
Before going to that extreme you could enter recovery, then clear cache, then go to advanced settings and clear dalvik cache plus fix permissions. These are cure all solutions but they may help.

I had this problem and it is down to the method you use time root.
If you use the toolkit method it will cause this problem
but if you use CF-root to unlock your s3 you will have no problems at all.
You can find CF-root with a simple search hope this helps

Thanks guys I'll give these a go when I'm able to after work. I have infact done a factory reset that didn't undo the root. I'll post back on either success (hopefully) or if my problem persists. I really appreciate your advice.
Thanks in advance. Danny.
Good luck.
As your problem appears to be caused by leaving WiFi on you might try this app
http://forum.xda-developers.com/showthread.php?t=1801284
I've been using it since early beta release. It can switch WiFi off when your screen is off. Obviously it will not cure your problem but it might be a work around.

hey guys. i gave them both a try. i cleared my caches. i even fully unrooted my phone. did a reset. and installed the root the CF-root package.
but still. im having the same problem. i really am new to this. and i just dont know what to do. all i need the root for is to keep my phone unlocked. i dont care for any fancy thing you can do once rooted. i think im just going to wait till a new software comes out that can be rooted.
hopefully it will have fixed the bug or something. really appreciate the advice you guys have given me. thank you a lot.
i guess until then ill have to remember to turn my wifi off before i go out :/
thanks. danny.
Unroot by flashing your original or a stock rom and test is the only way forward .

Hi all, i need a little help. I've just unrooted my galaxy s3, using stock rom 4.3. Everything has gone as it should and is now unrooted stock rom. But have noticed something unusual, in settings when i go to about device/software update/ and then press check for updates, nothing happens, it doesn't check for anything. I really don't know what the problem is, and i need to get it sorted as i'm a bit desperate for money and need to sell the phone quickly, but unfortunately nobodys going to be interested if it won't even check for updates.
Any help would be great.
Thanks in advance.
Hi there! Apologies if this is the wrong forum for this - I am currently having some issues with a phone that isn't listed in your database.
The model is a "Sonim A8" I believe, it is branded as Land Rover.
A friend of mine suggested that I might be able to get some help with the problem on this forum, so I thought it might be worth asking!
My GPS chip (originally functional) has suddenly started getting stuck in to a loop of searching for GPS servers. I have tried a factory reset, which did nothing.
Any ideas on how I might go about fixing this, or even if it is a problem that can be fixed?
Thanks for any help you might be able to give me and apologies again if this is the wrong forum!
