Cant connect to a network - General Questions and Answers

I got a THL W8 16gb yesterday and it arrived and I installed CWM designed for it and backed up the stock build and then proceeded to update to the gravitymod2 2.6 build for it. On this or the original build I cant seem to get any sim to connect to a network and sometimes even says error when looking for a network. Any ideas on what might be wrong or how to resolve it?

[Q] No sim card error

I bought this device less than a month ago from the carphone house when I was in uk. Today it gave me no sim card error suddenly. the device is not modified not flashed. I did nothing to it. I tried reseting the device but still having the same problem. I tried a different sim but had the same problem.
However, what I did notice that the device ask for the PIN of the sim card but as soon as I enter it. it gives me no sim card error
Any suggestion well be hopeful. Sadly I also lost the receipt
Are you using Agile Lock or any other lock or launcher app?
I hade that problem when I hade Agile Lock installed, removed it and not a problem since.
Thanks for your help but I was not using anything adding to that I did restore the device to its factory settings I did a complete (hard) rest for the device but still facing the same problem
I think I should have expected such a bad quality from LG
Anybody Help
Please anything
Hi, i had the same problem a few days ago, but on another situation.My phone was rooted and i tried to install "original firmware" to get rid of CWM and root, but at 42% of the process"Windows just crashed the LG updater", i managed to restore my old ROM trought CWM but got a sim card error, everything else was working but telephony.
Just tried it again like on this simple tutorial and got the original firmware installed again, and for my surprise telephony was back.
If you lost you receipt and dont live where you bought your phone, maybe this is what you can try.

XT926, sim card problem

Hello all,
I recently got the XT926 from Ebay. The phone had CM 10.2 ROM installed when I got it and it could detect my SIM card. Everything worked almost fine. I was able to access the internet through HSDPA and I was able to make calls. However I had issues with not being able to send SMS and MMS. I couldnt save the SMSC number so I decided to install the stable release of CM 10.1. I wiped, and flashed CM10.1 using TWRP that already existed in the phone. Now, after that, the phone will no longer detect any SIM cards no matter what operator or ROM I use. I live in Sweden and I'm using the GSM network. Wifi and all other functions work fine.
I even installed the official VRZ_XT926_9.8.1Q-79-1_CFC.xml but still its not able to bypass the activation screen because it wont detect any sim cards.
Any idea or suggestions on how to fix this?
Thanks in advance

[Q] No sim card detected

Hi, I'm new to the site and the scene and I'm having trouble which I hope someone can help me with. I got an LG Optimus One 2 weeks ago and it was work fine although it had some differculty detecting a sim card. The phone was stock 2.2.2 when I got it and I tried rooting with Z4root but that wouldn't work so I used gingerbreak then it wouldn't detect ANY sim. So I thought it might need updating in order to fix the issue so I hooked it up and used the official software and I still have the same issue. I'm not sure if it's the baseband or what but I've tried flashing v10 AND v20 basebands but it still won't work. I checked my phone status and it says the signal is negative like -100 dBm 6asu. I went to the hidden menu before and after updating and the baseband still shows as AMSS6038. I'm wondering if this is a hardware or software issue...anyone got any ideas?

[Q] Samsung GT-I9300 Not registered on network.

I am having issues with my phone not registering on local China Unicom network. First I updated my firmware to Android 4.3 UK version and I think this is what messed up my modem. I downgraded back to 4.1.2 and lost my IMEI. I then fixed my phone for $50 but I don't know how exactly the guy did. I upgraded again to 4.3 and lost my network again. I do not want to pay $50 again. This time I made a backup of my efs and restored my IMEI but I still cannot get to register on network. I have tried so many solutions but none seem to work. Just to avoid repetition I have updated my modem, installed modem files recovery ([DDEMG2 and XXDME4]), tried other custom ROMS and official firmwares but I keep getting the same error. I dont know how this Chinese guy fixed my phone but he rooted it and when I inserted the sim card it asked for network unlock code. I am writing this as it might be that my phone is set to locked version. I have also realized this has caused an issue with my cwm recovery which says E: signature verification failed. i am able to fix this by re-installing version 6.0.4.3 which then automatically updates or downgrades(I don't know) and brings back the signature error. I have my IMEI, anyone please help me with this.

Samsung Galaxy S10 (SM-G973F) doesn't register to network

I recently bought a used Samsung Galaxy S10 (SM-G973F).
At first glance the phone was in excelent shape. The SIM Card was connecting to the mobile network, and calls, internet connection, etc was OK.
But then, I found out that the phone had been rooted. Probably, by the seller. In pannic, I rushed to unroot flashing the stock Rom.
Here what I did:
1- Forgot to check my precisly CSC code and assumed ZTA (cause I'm from Brazil, and the phone is from carrier "Claro")
2- Downloaded the stock rom using Frija
3- Using Odin 3.14.1 flashed the device.
The previous rooted system was on Android 10 and One UI 2.5. With this new rom went to Android 11 and One UI 3.0.
The problem:
The phone recognizes the SIM Card. But it simply doesn't connect to the network. When I try to make a call it says: " not registered on network"
The phone DO recgonizes the SIM Card. On the SIM Card Manager shows my carrier name (Vivo) and my phone number. Also, the SIM app is showing on the app list.
Things I tried:
Rebooting the phone
Changin the SIM Slot
Testing the SIM on another device to ensure it was working
Checked if the IMEI wasn't missing/undefined. It is not, the IMEI appears to be untouched
Checked if the IMEI had been blacklisted. It's not.
Flashed SEVERAL different stock ROMS with different CSC (ZTO, ZTA, ZVV)
Try to manually select the network. This also throws an error saying "error while searching for network"
I'm really desperate and don't know what to do anymore.
No one have a clue either? :C

How to Fix 'Not Registered on Network' on Android
Here is how to fix 'Not Registered On Network' error on Android. Mostly error occurs on Samsung phones, but this solution works for all android phones.
www.android-recovery.net
Wow,
This is exactly like my S10 right now.
At first, all is good, the signal was great, all working well, except cant connect to samsung pass and samsung health because it was root.
then i brought to sellular shop service, to flash the phone.
Then, “not registered to network” happened. The signal ok, the phone able to read dual simcard, but “emergency call only” and if i try to search network manually, “error while searching for network”
And the sellular shop service have no idea how to fix after they reflashed and try to fix it for several days.
Have you found any solution to fix your pho?
pls advice…

So, were you able to find a solution for this problem? I also bought a Note 9 N960F/DS recently and found out it was actually a N960N model that was changed to N960F/DS. So I did exactly what you did, I flashed the original stock rom, N960N, but now phone will not connect to network. I also did hard reset, reflash other stock roms, nothing changed. Anybody with insight should please give us some pointers.
