[Q] not registered on network. Galaxy 2 - Galaxy S II Q&A, Help & Troubleshooting

Hi.
I have a big problem with my G2, and have tried many things.
It all started 2 weeks ago. I lost connection to my network.
I tried many things, and ended up giving it to a repair shop, in China, as I was there shortly. They put a new firmware into the phone, and a chinese SIM card worked.
I found an english version of the firmware, and asked them to update with that version, No problem. Everything worked well...but when I arrived back to Denmark, same problem. Not registered on the network.
Now I have tried many things, as Kies could not recognize the firmware version. I burned a 2.35 version into the phone with Odin, and Kies regocnized the version, and now updated to 4.03. Great, but ... I have the same problem. APN settings acc to my network provider. Oister 3 in Denmark.
I really have no idea what to do anymore. And I cant send it in for repair, as the flash counter says 10 times.
Is ther someone here, with a very deep knowledge in Logs etc, as I can send Logs if I am explained what to do.
The short time the phone worked, did I really love it.
And also the chinese SIM can not connect from Denmark.
I would prefer all Logs etc in private email, but if we solve it, I will poste solutions and results here.
Best of regrads

As for the counter, install and run triangleaway - it can be found in the SGSII section of XDA.
Check that the sim card works (try it on another phone) and borrow another sim card (on the same network). It is amazing how many problems like this are due to a damaged sim card or just not connecting correctly. I had a friend who took the sim card out to flash their Samsung Galaxy 3 and put in the sim card wrongly and couldn't make a call.
Can you copy your contacts to or create one in the sim card?
I doubt that it is a problem with the EFS folder, ie no IMEI number because it was fixed with a china sim, but it may be. Is the IMEI number you get from dialing *#06# 004999010640000 or different from the label under the battery? If so then you have a EFS folder problem. There is an app that may fix it - it requires root - * HERE *

Hi
Thanks for the reply.
A:
I can make, copy, edit etc contact directly at the simcard in the phone, and also copy, edit etc from Kies to the Sim card. And yes. It is the simcard I can do those things at. Double checked that it was somcard and not the phone memory
B:
Double checked the IMEI number again.
Label phone same as *#06#
Further information:
In the first day, I tried many many things to get the phone working.
I searched the internet a lot, and I found some kind of help. Like with IMEI check, I should type a code like *#xxxx# or *xxxx* Stupid as I was, I did not write down the code, and also did not safe the page on the internet, so I have no idea what code I wrote. I am sure it was something regarding Mobile network or CSC.
Reg Triangle away.
My phone is no longer rooted, as I try to have it in original mode, so its ready to send to repair, if needed. Triangleaway needs the phone to be routed, right ?
And will that not require an unsafe kernel ?
After resetting, then I suppose I need to install an original kernel again, and will that not make the counter go to 1 ?
Any other ideas ?
Regards
Morten

can you be little clear....
no network or no data (internet) on your current network
1: do you have a locked phone or unlocked. [carrier locked when new]
2: no network will be no signals at all, no phone call....
3: no data will be you cant browse, send receve emails
4: counter can be fixed easy as now your on ics

Hi,

1. my phone is unlocked(international).
2. signal show full, but no phone call
3. I don't use data, but wifi, and no problem with wifi.
Well, this : not registered on network only happen if phone idle for more than 3hrs, meaning phone just work normally if I don't let it idle for long time. This very frustrating as every morning after wake up I have to switch between airplane mode for phone working again.
Greatly appreciated for your help
Thanks in advance
P/s: currently on Slim rom(cm9). But have tried almost all custom rom found in xda, problem still exist. Even try to change CSC to my current country( Thailand) on stock DL7( included Thailand region), no luck. APN setting also change to default network provider.

Mobile network problem
Hi.
Please see my answers below
1: do you have a locked phone or unlocked. [carrier locked when new]
The phone worked before, and was not locked, but as I send a command to the phone, could I have locked it ? How can I check that ? And it does not give me any warning when I start the phone up.
When I try to make a call, it right away says: Dialling ...Call ended.
2: no network will be no signals at all, no phone call....
No mobile network. It is ONLY a problem with phone calls and reciving calls.
I have plenty of signal
3: no data will be you cant browse, send receve emails
Data is right now not working, WiFi works.
I cant get correct APN settings, as my provider sends this as system configuration to the phone, but cant recive it.
3A: My provided is named 3 Oister, and normally this provider is listed under Network operators. On this phone it is NOT listed. 3 Oister is using network of 3, and only network of 3 is listed.
If I pull down the menu from the topbar on the phone, it actually says 3 Oister, but 3 Oister is not listed under Network Operators.
On my other SG2, 3 Oister is listed in Topbar and under Network Operators.
I bought a new SG2 as well, and we are 2 persons using SG2 here.
4: counter can be fixed easy as now your on ics
How ? Can I do that without rooting and install different firmware ?
I do run ICS ver 4.03, updated by Kies.
In worst case, I will send the phone in for repair, but for sure, needs the counter reset.
Regards
Morten

Put a new firmware in the phone then probably wrong modem and CSC for your location .
Chinese sim unlikely to work 4000 miles away but that is easy to swap sim .
Rom counter for ICS use the search tool for the relevant post .

Mobile network problem
Hi
Please find answers below:
Put a new firmware in the phone then probably wrong modem and CSC for your location .
As my counter says 10, you can see, I have tried this several times, and its also written in my first post.
Please send the code for check of CSC and changing CSC. As I remember it is set to be NEE.
Chinese sim unlikely to work 4000 miles away but that is easy to swap sim .
Chinese SIM works all over the world, as long as Roaming is allowed. And it works in the other phone. Now I have the Denmark SIM in, and same problem. Yes, I did close down the phone, changed SIM and started the phone again. Exactly SAME problem.
Rom counter for ICS use the search tool for the relevant post .
Would be nice to have the info written here instead.
regards
Morten

Sim CSC Modem . Firmware .
Then your answer is hardware fault if above are ruled out as not a problem.
Rom counter for ICS use the search tool for the relevant post .

Sorry i refuse point blank to search for someone else .
Neither do i have the relevant post bookmarked otherwise it would have been posted .

try this before you send for repair.......
get this stock for your network
http://www.hotfile.com/dl/149692036/21dfd27/I9100XXLPQ_I9100HTDLP3_HTD.zip.html
1: forget all your idea's do exact as i say
2: remove your sdcard
3: using cwm format system, cache, data, sdcard [system is a must]
4: remove battery / insert back goto download mode
5: flash the ROM you downloded using odin, after restart dont do any restores
6: wait for few minutes now dial this *2767*3855# [important]
dont restore any backups including titanium stuff.
if your phone works now put your sdcard back and do whatever now you want.

next time start your own thread........ this time im helping
do as i posted for the OP but instead of his firmware download your country specific firmware.
seems as a modem issue but can be sim related.

Mobile network problem
Hi again
Followed the guide very detailed
3: using cwm format system, cache, data, sdcard [system is a must]
Wiped all data in System and also Wiped Cache, using:
Root the Samsung Galaxy S2 GT-I9100 running XXLPQ firmware and install ClockworkMod Recovery: CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.tar
Done with Super User Granted.
4: remove battery / insert back goto download mode
Done
5: flash the ROM you downloded using odin, after restart dont do any restores
Flashed with Odin 1.85 in PDA: I9100XXLPQ_I9100HTDLP3_I9100NELP2_HOME.tar.md5
6: wait for few minutes now dial this *2767*3855# [important]
Done. Phone shows Factory Reset in big letters
dont restore any backups including titanium stuff.
Nothing restored.
Booted up, and automatic installed APK's
Same problem.
Only difference is that now the counter says 11 counts
But thanks for a detailed and well told possibility.
As I see it, the problem is connected to the standard the phone connects to the Mobile grid. As I told earlier, I made a stupid thing. I send a command with *#xxxx* in the phone, and I cant remember what code, and I did not save the page on the internet. I really think the problem is about a standard. That the phone is setup to a standard that the 3G net is not using in Denmark.
I can dump logs etc, if anyone can help. But I need to know how.
Regards
Morten

---------- Post added at 12:06 AM ---------- Previous post was at 12:01 AM ----------

Mobile network problem
Hi
Nope. Did not solve the problem.
Just ran Triangle away, and moved the Firmware: I9100XXLPQ_I9100HTDLP3_I9100NELP2_HOME.tar.md5 to the SD card.
Will try now to install it by CWM
And then I give up. Will try to send it for repair ..... really a shame, as I really would have liked to solve it here
Cheers
Morten

Mobile network problem
Hi Buddy
It finds a lot of Networks, but cant connect to any of them
3 networks with 3G and 4 with 2 G
But not the Mobile network I need to connect to> Oister 3
My other SG2 finds that network without any problem
Cheers
Morten

I had the same problem too. At first I tought it was a rom issue, but it wasn't actually. I turned my phone off and removed and placed back my sim card and it worked.

Mobile network problem
Finished programming original firmware using CMW as source for Odin, after counter was reset to 0, and the pnone status is the same as before, but counter is 0.
So will try to send it in for repair.
Thanks to u all.
And SIM card has been removed several times, even tried with a different.
No luck at all
Cheers, and thanks again
Morten

Did you ever get to the bottom of this?
I've been using my phone in Brazil and now i'm in the UK, it's doing exactly as you describe.

How would you go about checking these?

Compare the IMEI that displays when you type *#06# to the IMEI printed on the label under your battery. They should be the same.
For your own sake, do NOT post what the IMEI under the battery actually is, whether it's the same as what's displayed when you dial *#06# or not.
As for checking IMEI blocking by the carrier, that should be obvious. Call your carrier.
