Suddenly no signal / reception - Galaxy S II Q&A, Help & Troubleshooting

Hello guys,
I have a severe problem with my SGS2.
I was using it as always when suddenly my signal strenght dropped down to 1 bar and since then it's changing between 1 bar and "no service".
I have been running on CM10 Nightly 20120910, thus I thought I'd try another modem. Flashed XXLQ6, nothing changed.
Then I flashed the 20120908 nightly - no change
flashed CM9.1 with XXLX/XXLW modem - no change
reflashed CWM Kernel - no change
I tried using another Sim-Card which operates in another network - no change, still only 4% signal strenght (looked up using Network Signal Info)
The I tried using my current Sim-Card in another mobile phone, and there it worked flawlessly.
WLAN is still working, but no GSM/UMTS. Even if I have 2 connection bars for some seconds, I still have no internet connection via UMTS during that time.
Anybody got an idea?

I'm facing the same issue. Did you solve it?

If it happened suddenly and the problem persists in other phones, than it's your network operator cell.

The problem doesn't persist in other phone. I've tried the SIM in two other phones and it works perfectly.
Also tried another SIM(which works on some other phone) but don't work on mine.

Hi!
Since you are new here, it may be the best time for you to read the forum rules not that you've done something wrong but just to inform you about it
Here's the list of modem that you can flash http://forum.xda-developers.com/showthread.php?t=1131950, it comes along with a guide..
Since everything you mentioned failed, i suggest you flash back to stock firmware and do a factory reset it might just do the job..
i hope this helped you, cheers!

Thanks for the response. But I've tried flashing the stock firmware with factory reset and what not. I'm still facing the issue. Kindly help me.

update:
Upon your insistence, I flashed the official stock again, did a factory reset. Still facing the issue. Flashed two different modems again. Still no luck.
Restored by original EFS, no luck. Fixed RW of EFS folder. No luck. Still the same issue.
Please help.

Sorry I didn't read
If you've already full wipe'd your phone and then installed a stock firmware and the issue doesn't solve yet, it may be a hardware-related problem, also because you said that another SIM, working on other phones, doesn't work on your S2.
Try another full wipe and install a different firmware, and if still not, I don't know...

[Q] no 3G

hi guys, just about 2 days ago i rooted my phone. problem is after rooting my phone can't seem to get a 3G signal anymore. only GPRS which is so slow! need help tried reflashing with a stock ICS ROM and still no go.
EDIT: here are the things i did before i noticed the disappearance of 3G
1. downloaded recovery and kernel from tegrak's website.
2. booted into download mode and flashed the recovery.tar file
3. booted to recovery mode and flashed the .zip file
4. installed Tegrak Kernel & Superuser from Play Store
*this is when i noticed that i can only get GPRS/1x signal
what i did after was kept flashing a stock ICS ROM. nothing happened to fix the 3G problem.
searched the forums and none of the method works. tried reflashing stock ROM still a no go.

already did sir, still no 3G signal. i'm 200% sure my area has 3G.. it even reaches 3.5G on my other phones.
okay.. just noticed minutes ago that my other phones are getting up to 4G signals too. and my Galaxy Note can't even get to 4G? its really stuck at GRPS speeds. the root must've messed up something because this is my 3rd reflash of a stock ICS ROM and still stuck with a G signal when data network is turned on.
EDIT: been lurking around xda-developers forums now, even tried other websites... is it possible that a kernel flash could change the radio of the device? reflashing for the 5th time did not do anything for me. after 5 tries (i know, that's too many to figure it out that it doesn't work), i've given up. if anyone has a solution to this problem please message me.
ok guys after a few days of testing. i finally figured it out.
for some very odd reason, this particular sim of mine says "network type: GPRS"
i tried different sim cards of the same carrier (i repeat, the same carriers) and it says "network type: UMTS"
even tried different sim cards from other networks and it says "network type: HSDPA"
so that is very odd. did flashing ruin something on this simcard? i can't really pin point?
anyway for me this problem is solved. i'm getting another sim card hehe. hello again 3G/4G!
EDIT: I FOUND A SOLUTION! its not the simcard, its the band setting! i just switched from GSM to WCDMA and it worked for that sim! there is a secret SKT Telecom menu for the Korean android phones that lets you change the band.ΓΌ

[Q] Galaxy S2 unable to register to network, no signal

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.

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.

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

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)

"Not Registered on Network" Error. Most "solved" threads tried.

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*

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.

[Q] Lenovo P780 (probably not ROW) unable to change modem.

Hello everyone.
My problem is simple, I can't change the modem.
More information:
I got my P780 some time ago with 4.2 from the vendor. For some days now, the device was softbrick'd. After a complete flash and 3 days of back and forth I got 4.4.2 S221 Life installed with TWRP and CWM recovery (can easily change between). With this version i actually CAN (miracly!) connect not only to 3G, but to 2G!! (Only version so far for me)
If it helps, I live in Germany and probably got the chinese version (chinese letters written on battery)
Problem is, the connection is not very stable :/
So I decided to switch the modem to v51. That's where the problems start. I got the zip on the ext_SD, flashed with TWRP and CWM and wiped the cache. But the "Baseband version" is still at "P780.V101..........", even after several modems, it does nothing!
My second problem is, that the WLAN-connection only works once. I enter the password, it works and after I got out of range and back in it won't connect again!! I have to "Forget" the connection and connect all over again with entering the password.
I really hope you can help me

what i found is Alice Project Rom gives you the best wifi signal and somewhere in stympy s post you will find attached modem .. now that you are in germany i think it will work best for signal... just flash it from recovery

Thanks for the quick reply.
Unfortunatly this doesn't help either. I flashed it, but the signal strength is nevertheless bouncing between nothing (maybe 10db above noise) and full reception. Also in 2G as well as in 3G.
AND the Baseband version haven't changed at all (still v101)
what i noticed is with Alice Project i got the best signal reception for WIFI and for phone also ... its using baseband of S920.V101 may be thats why...
or alternatively serach for S920 modem drivers and give a try ..
cheers

I tried nearly every modem I could find (around 15-20) but none changed the baseband version or anything.

Not registered on network

Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...

That was a guy who work in service, I don't have his contact anymore... but that's what he told me...write that chip in motherboard and get new imei number...it was very expensive, almost a half price of the phone...

I know the topic is old... But I have the same phone and the same network error. Has anyone here managed to solve it?
