Hi,
I'm facing this major problem with my handset.
When I insert a SIM card to my mobile, it registers with the network (VODAFONE IN) with signal strength of 12asu and then gradually decreases to 5asu and then 1asu when my phone shows no signal afterwards. The carrier is shown as Unknown and service as out of service.
If I put the same SIM in another phone, it works. So no problem with the SIM or Network.
I have tried the following:
1) Flashed various modems
2) Flashed various ROMS (CM9, CM10, Official Stock)
3) Did complete WIPE. Factory Reset, Clear cache, Clear Dalvik cache, Format /system
4) I also restored by efs to a backup I had of my efs(taken when I first got the phone in 2011).
5) Also used Repair Galaxy S2 app which basically fixes RW permissions of the EFS folder.
6) Also used EFS Pro to repair my .nav files
7) Also used GetRIL tool to check if the drivers are matching.
Even after doing everything, the problem is same. When I first insert the sim card, it gets signal for around 5 minutes and then suddenly it goes to 1asu with no signal forever. I also kept my phone as it is for one whole day, but nothing: my phone is unreachable and there's no signal.
I had never dropped my phone and possibility of any physical damage to the receiver is very low.
The only reason I can see is this:
I was on DilDroid ICS and everything was fine until one day, I went to Recovery and fixed permissions. (Btw, DilDroid ICS used Siyah kernal)
And I think that was the last thing I did after which my phone couldn't receive signals.
I think some files have been corrupted and even after factory reset etc. it remains and the next time I flash another ROM, the files are still there.
Can someone tell me a way to completely clean my galaxy s2 and then start off by flashing a new ROM.
Or any other solution. Kindly help.

do a full wipe and install another rom and see
1) Wipe data/Factory reset
2) go to 'mounts and storage' and wipe data and system there.
3)wipe Cache partition as well as Dalvik in advance.
then install the rom zip file
and again do all wipes except system and then check for issue's
ps- before that try with a different netwrk sim on the phone and see if the issue persists or not

Hi Sun90,
I've tried flashing different ROM after complete wipe. I also wiped system. But never wiped data. Doing it now.

update:
I tried your approach, but still facing the same problem. Please help.
Hello everyone.
I got exactly the same problem. I had my I9100 for over a year. I flashed lots of roms. Now i got this problem. I cannot connect to the service of my carrier. I got realy bad connection or no connection at all. The sim works on different Galaxys and its not a problem with the apn and or my IMEI. Evereything is ok there.
what have I done so far:
flashed several roms
flashed several modems
went back to original rom
several whipes
Now I have a nice MP3 player with some WIFI at home
What im thinkin about could be the problem but I dont know how to fix it:
I think i got a wrong CSC and there is something rotten with my partitions...

yes i tried another networks's sim as well. sim was recognised. sim-pin ok. but no service/connection. on manual carrier choice the galaxy said something like connected to service. but there is no internet and if i try to make a call there is the "no service" popup again.
i dont think its a problem with the HW because sometimes i see the different carriers. i just cannot connect to them!
as I said before: I think its a SW problem around CSC and/or somethin is ****ed up with my phones partitions...

That's true. If I sometime connect to my network, I can quickly make a call & for the duration of the call, it remains okay. Pretty strange. I can goto flight mode and then back and sometimes I get the signals back for around 2-3 minutes before again going to no signal.
@Aton88, Were you by any chance on Siyah kernal or DilDroid ROM or went outside India? Just asking. Trying to find a pattern here.

yeh sure, give it a try
and by the way creating more threads for the same issue doesn't bring about any goodthing to u for sure, hence stick to the rules of XDA, rather than doing this and getting Infracted by the mods for the same
take my words this is for ur own good

Thanks for the advice. I shall make sure I don't create duplicate threads. Btw, I even checked if my phone is locked but it's not. Everything is OFF.
I even checked the validity of my IMEI and it seems to be valid.
I'm really running out of ideas to check what's wrong.
I tried a different provider's SIM and even that doesn't work.
Can someone tell me how to do a complete clean install.
Are these steps complete or any steps are missing:
1. Factory Reset
2. Clear cache
3. Clear Dalvik Cache
4. Clear Battery stats
5. Wipe /system
6. Wipe /data
Then Goto Odin: Flash the official Stock Firmware for India.
Am i missing anything? I want a complete WIPE, so that no previous corrupted files are present. Please help.

u can give it a try with those steps but no4 is not necessary
i have a similar problem.....in the about section my network is displayed correctly but under "service state" it says out of service... BUT the internet works fine....when i try to make a call it says "not registered on network" ...the sim works fine in other phones.....the IMEI is also fine.
heres what i have tried :
1) change sim card
2) change roms
3) go back to stock GB that phone came with
4)wipes (all)
now i think i messed up something with the ril cause i changed it and i think thats where the problem started.
i got backups of the efs but i dont wana go there unless absolutely sure that the problem is there.
(is there a way to i dont know like check the integrity of tue efs or something)
I'm having a similar problem with my s2
Sent from my X10i using xda premium
if someon could plz check this for me.
i went into the service mode menu *#197328640#..then option 2 which is version info ...then option 1 which is SW version....then option 1 which is READ IMEI ...now when i selected that it said IMEI :NOT SUPPORTED
i dont know if thats normal...so if someone could please try this and let me know..i would be extremely thankful
ok so i did a lil experiment :
i purposely messed up my IMEI to that generic one with lots of zeros ...and suprisingly the calling function is back and i can use the phone normally except ofcourse the fact that the IMEI is messed....
Then i restored to get my own IMEI ...and together with my IMEI ..the problem came back too....
(oh and once again if someone could plz confirm the thing i asked about in previous post thanks)
My imei says not supported "/

Network signal issues
Have you tried checking network operators and manually searching and selecting the Network provider?
also have you tried flashing a different radio ?

Hi guys,
I have a huge problem. I had a stock GB firmware customized by Optus (carrier in Australia) on my S2 I then decided to change to the new ICS 4.0.4. I downloaded the stock unbranded firmware from SamMobile (Australia 2012 September 4.0.4 I9100XWLPW, I9100XSALP6, XSA) I updated using Odin. Before I did the update I reset the phone, did the update, it all went smoothly. After the update I reset the phone again and then proceeded to reinstall all my apps and restore my contacts, sms, etc.
The phone works and all functions on it work, however now very randomly the phone would totally freeze. The phone would be in standby, the screen would come on and it would be frozen. The screen stay on all the time and it does not respond at all. It will stay frozen until I restart the phone by pressing Home+power buttons to restart it.
After restart it all works fine for a few hours, sometimes a day and would just lock up again. The phone is not rooted and as I said i just changed the firmware from the Optus branded GB 2.3.6 to unbranded stock ICS 4.0.4 by using Odin.
Is there a way to find out what is causing the phone to lock up like that? Any suggestions would be helpful.
and then proceeded to reinstall all my apps and restore my contacts, sms, etc.

I made sure that I didn't restore any data apps. The only apps that got restored are the ones that get automatically restored by Play store.
I have disabled the live wallpaper that I had and it seems to have stopped the freezing for the moment. I will report on what I find out.
In the mean time if anyone else has a similar issue or has a definite solution please let me know.
Thanks
i know this is a resurrection, but don't see it has been resolved.
also found same/similar problem on another topic, but no resolution either.
couldn't find any resolution anywhere on the net, but possibly i'm just missing it (searching for wrong parameters?)
anyway, a friend of mine bought second-hand (third or even fourth hand to be precise) i9100 with 2.3.6 (stock KI3) on it. the guy who sold it to him said something like: "it works best on 2.3, on 4.x it's buggy".
it was working fine, but friend wanted newer OS, so we tried update. it didn't work, and i found out CSC was broken/missing. somehow i managed to repair it, and update was finally working, but was unable to find any for our location.
so next step was to find stock rom that would work on the device, and then i tried four different 4.1.2 stock roms from this topic.
after flashing it through odin, every one was acting fine, until couple of minutes after it started freezing or rebooting randomly.
then i tried flashing CWM, and flashing from sd card, but it was all the same.
wiping data, cache and dalvik cache, prior to flashing. wiping data after flashing...
nothing seemed to work.
GB works rock solid, ICS works better than JB, but stills it freezes or restarts randomly.
tried CM10, but all the same, except it works a bit faster then official JB. but who cares about speed if it freezes/restarts constantly?
back to who knows which build... freeze... samsung galaxy s2 - i9100... with yellow triangle... booting stopped.
so i decided to dig deeper, trying to find hungarian stock build (country we were told the phone came from) not being sure that KI3 is what the phone came actually with. i found 4.0.3, put it on SD card, wiped data, cache, flashed CWM, wiped data, cache, dalvik cache, flashed 4.0.3 from sd, wiped data, booted, entered location for updates - hungary. update found, hooray... downloading... installing... rebooting... working?
nope... it's worse than ever. trying to log onto google account. typing in email add.... freeze... switching phone on - freeze... thinking about... freeze.
i couldn't sit still. yellow triangle, all those reboots/freezes... at least i wanted that triangle gone, and without a JIG, there was only solution for me was to try triangle away. it wasn't available for download in my country from play store, so luckily xda was there.
somehow i managed to download it from the device, install it, click remove the triangle... it did it's magic, rebooted... and miracle happened!
no more freezes.
so i started torturing poor phone, benchmarking, playing games, listening to music.... it seemed stable for about an hour.
so i said to myself:
- it's possible that previous owners tried to upgrade it to newer firmware, and somehow screwed up the bootloader, which was fixed by this app? maybe that was all there was from the beginning? why not try putting 4.1.2?
and i did... took 4.1.2 spanish build from already mentioned page above, flashed it... and voila. working JB... torturing the phone... playing with it... hour passes, another hour...
friend wakes up... takes his phone in awe, starts playing with it.. we talk a bit... and then that look it just froze again!
from that moment on, the phone again starts restarting or freezing randomly...
and, yes, i still have no clue what could be the cause. it doesn't matter if wifi is on or off, if you're talking on the phone or not, bluetooth and gps are always off. only thing that he noticed is that it usually happens while he's using the phone (meaning: operating the digitizer or buttons). if he starts music playback and not touching buttons or screen, it will probably play for hours.
one more thing, but i doubt it would be the case. the battery in the phone is not original one that was shipped with it, but a quality replacement.
it doesn't feel as if the phone is overheating... so i don't know what else i could do with it.
for now, it's back to 2.3.6.
we both lost a week, torturing ourselves with this problem.
i don't know is there anything i could add more?
all suggestions are welcome.
cheers
Maybe try kernel cleaning script and try philz or siyah kernels.
You shouldn't have to flash a custom kernel so your phone won't freeze, but yes, you could run a nuke script in order to wipe clean all custom ROM's leftovers.
Try flashin' jb via mobile odin, see if it keeps freezing up on you. If so, nuke it up.
Sent from the little guy
i'll try them out.
probably for the weekend, if not sooner. will report back here with info.
any other suggestions are also welcome.
thanks a lot.
cheers
ok, so here are some updates.
i finally got my hands back on my friends phone, and tried nuking remains of older flashes.
following that, i flashed stock spanish rom from above mentioned page, updated after installation to spanish update... and after a few minutes, sudden reboot...
so, went back to nuking, and flashed stock hungarian 4.0.3 i found elsewhere (mentioned in my earlier post. don't remember origin... if i find the link on another computer where i downloaded it on, i'll post the link). tried updating, says no updates found.
started torturing the device. it seemed solid, but battery reported it level was low, so hooked it up onto charger and all seemed well. but phone seemed a bit too hot.
after few minutes (this was all about half an hour to hour after flashing to 4.0.3), again freeze.
after rebooting the phone, battery was at 9%, as if processes were draining battery faster than charger recharged it.
so, i figured i gotta try original battery. so i switched his battery with genuine from my phone.
phone seems stable and less hot, for now.
still checking if it is going to freeze or reboot again.
it's about one hour since battery change. still on charger and using wifi and playing around with apps.
i'll check in with news later.
cheers
I have the same issue.but my battery is original.
What I noticed that the phone stuck when I receive an update notification.
Can I stop softwsre to ask for updates? ???
Sent from my GT-I9100G using xda app-developers app
^go to settings, about device, software update and detick auto update. that should stop it from trying to self-update.
ok, so here is an update to my friend's phone status.
currently on hungarian 4.0.3. about 3-4 freezes/reboots a day. sporadic connection breakups during calls. also, when we talk i can hear myself back. this brings me to conclusion it has to do with modem firmware. i found this topic, so i'll try putting that and see what will happen.
if that doesn't solve anything, my question is this: is there any way of knowing which firmware/rom was originally put on the device, since i don't know the real background of the device? i.e. some way of entering IMEI and finding out what should be on it?
cheers
EDIT: tried KH3 modem, no changes... i could still hear myself while talking to my friend on that device. also, it froze couple minutes later. going back to 2.3.5-2.3.6 for now.
so after couple of months, i finally got my hands back onto this phone...
gave my friend my phone, so i could play a bit with this faulty one.
i have played with it for a couple of days now, and here are things i've tried.
i received it from a friend with 2.3.5 on it which had triggered custom binary counter. he's been using it for couple months without any problems.
so i rooted it and installed triangle away again... reset counter, cleared and flashed hungarian stock (telenor) 4.1.2... random freezes again.
tried several stock roms, mostly hungarian ones (4.0.3, 4.1.2). even reformatted with .pit file... random freezes.
reformatted again with .pit and put XXLSJ, installed stability test and let it run...
cpu stability test 15.5 hours no problems, no freezes. then i realized it didn't have a sim card, so i rebooted phone and installed sim card. let it test cpu+gpu for 9 hours... no errors, no problems, no freezes.
so i thought, maybe it's all fine? but it wasn't! as soon as i took phone into my hands and started going through menus it froze!
so i tried SGII_repair, rooted and did "repair"... but nothing changed... still random freezes.
if i just let it do the stability test, it'll probably work forever.
things i've noticed:
- serial number is wrong format (14 hex digits instead of 11 alphanumeric)
- during stability test, cpu frequency dropped from 1200 to 800 mhz (maybe because it was getting warmer? 42-43C during cpu only+charging battery, and about 39-40 during cpu+gpu test)
i tried to find out which firmware is latest according to serial number via kies, but it gave me error.
i know it's from hungarian market, but don't know which exact part of it (branded or not).
don't know what previous owners did to it, and don't have backups of original efs or anything original.
i just want to make it work, don't care much about custom firmwares. i'd be happy even with unrooted stock... just for it to work!
i have no ideas what else to do.
anyone?
finally, as i couldn't resolve the problem, i returned phone to 2.3.5 and sold it as is.
thanks to all people who tried to help.
cheers
Hello
I just ran into the no SIM detected problem many people already had. This happened after having flashed Pount ROM CM 11, after which I tried to restore my stock ROM backup with no success. I also get signal.
I did some lookup, and it seems most of the time the obvious symptom is the loss of the IMEI.
However my IMEI is fine. My baseband is also correct. I tried restoring the whole "efs" folder which I had backed up a few months ago, but still no go.
Which other options do I have? I'd gladly read some other thread but I could not find any other similar situation - maybe because most of the time the IMEI is loss.
Can I get some help? Thanks!

I'll just answer myself as I kept on investigating and it may help somebody observing the same symptoms: the SIM card was simply dead. Yay, my I9100 is back on track :victory:
Hey guys!
I'm currently getting the "not registered on network error". I have tried any; if not all threads on this issue to no prevail! It started when i flashed my phone to a deodexed version of the stock firmware for my phone.
What i have tried;
Used my simcard in other phone (Works fine)
*#06# brings up the same IMEI string as the one underneath battery
Using another simcard in my phone doesn't work
Used Kies Emergency Recovery to flash my phone back to complete factory reset
The strange thing is, i then thought after my efforts, i've had a hardware failure. But when i scan for my local networks, i see them just fine. Which would presume the antenna is operational. *see attatchment - Screenshot_2015-01-09-02-30-32.png*
Try patched modem and kernel, restore efs backup.

Thanks for the reply.
I think it's on it's way out. The phone is touching 3-4 years old now. One of the first to receive the phone. It seems to be a power issue. I did the above solution yesterday evening which didn't work. However, the phone IS currently working perfectly above 45% battery. Have you ever come accross this issue before?
Is the battery swollen? Try another battery.
So,
I bought this phone on the day it was launched, its been more than 3 months and had no issue with the device. I rooted the phone , experimented with Xposed and other apps but for the past few days i was experiencing this strange problem. Cellular network was not running on my phone, i changed the sim, swithed the devices on/off several times , did everything i could do in the os, changing the mode to 3G from LTE and vica versa, etc etc .. but still no luck. The cellular network sometimes comes and goes. Then i opted for last resort which was to factory reset the phone, after resetting it the cellular network worked but i don't know if this is a permanent solution. If you have anything to add please share.
Regards,
Saransh
Sorry nothing much to share but i suspect you install some apps or did something to your rom so the network screwed. My suggestion is you nandroid backup every week (at least) so you can revert back when something happened.
Tried factory reset
I have tried factory reset but still having this issue. Maybe it's a hardware issue. I don't get it , everything was working fine few days ago then all of a sudden this **** happened.

Maybe exposed screwed something. Get a microsd card with whatever rom you want in it. reboot to recover and try full format. insert the microsd after then flash a rom. see if it works
Rooted my phone with sudamod rom, Everything is working fine.
