Help, I can't connect to mobile network - G2 Q&A, Help & Troubleshooting

Hi everyone,
Two weeks ago, I bought my LG G2 to someone. The phone is with Telus but it's unlock. So I use it during two weeks with my Bell sim card without any trouble.
This morning, I was on facebook and 30 sec after I loose my mobile network. It's searching for service none stop since 1h. I rebooted the phone couple of time, no effect. Remove the sim, reboot, put sim back, reboot, no effect.
I'm in Canada and the carrier has started to lock stolen or loosed cell phone about less then one month ago. So I'm worried about my phone was stolen and has only reported stoled like yesterday or I don't know.
I'm freeking out I pay 500$ for the phone.
Could it be the sim that relocked ? When my bell sim is in it search for network with the little cercle turning over and over.
I think I'll reset de phone and pass to bell at my lunch time.
Help me please !

Selling hero for £150

I am thinking of selling my hero for round £150 because i can just not sort out the problem it has so maybe some1 with abit more knowledge will be able to sort it. It all works fine apart from the problem with the sim card which is for some reason it does not register any sim cards. The phone is unlocked and i was using a 3 sim card in for about 2 months but then all of a sudden i lost connection and then i could not reconnect with any sim card =/ i have tried different firmwares and radios but nothing seems to help. It certainly isn't barred i know that so i really duno what is up with it but would be a bargin for someone who does know. P/M if your interested
It ssems like phone has been blocked.Did you buy it from previous user? Contact him/her , or the branded supplier with imei number for their explanation.
no it use to be on contract but had a problem and came off but it hadn't been blocked by them i was using it for a while after i had come off use to work fine then it just did this. I have heard there are problems with 3 sim cards sometimes thow so wondering if it was the sim cause other sims just get stuck on the registering bit like the sim unlock hasn't worked
Just curious, but why haven't you contacted whoever you bought the phone off?
Definitely sounds to me like the handset has been barred. If you bought it as part of a contract, but then cancelled the contract early, well it makes sense for the operator to bar the handset if you didn't send it back.
Quick call to 3 (assuming that's who you bought it from) should give you an answer.
no its a tmobile i shall ring them tomorrow see what they say
Wavesecure in ROM, allowing to lock / locate / wipe your device remotely in the event of loss and be notified if the SIM is changed.
that doesn't really solve none working sims though does it ?
iv just paid for an imei check and just waiting for the result now
this phone is blocked by tmobile but not by other networks that is why it registers on tmobile but wont make calls or texts so am wondering if its something to do with the unlock code iv put in =/

[Q] Question about 8525 failure?

Hi all - I believe this is the right place to post so here goes. I had an 8525 which I successfully unlocked with HTC_Hermes_SIM_SID_Unlock_v3a and also applied Hard-SPL-V7 successfully.
For the last two months I had installed at least six different ROMs without any difficulty or problems.
Wanted to sell the phone on Ebay and move on to another phone so I "restored" the phone to almost stock with RUU_Hermes_CINGULAR_WWE_3.62.502.3_6275_1.54.07.00_108_UOOS_SVN05_.exe
Shipped the phone to buyer and got this email back.
"put my Movistar simcard in
int.roaming
with At&t, it asked me for an unlocking code and
like 3 minutes later
after that it turned off and doesn't turn on
again, even after 5 hours
of charging. What shoul I do with
it? thanks."
Any ideas would be greatly appreciated.
TIA,
Littlalex
From what the buyer is describing, the phone isn't unlocked. Have you tested out with anotehr carrier SIM card before shipping?
If you used the phone throughout your contract, i.e. until it's over, I think you can try to call AT&T customer service and say when you tried to use T-Mobile's SIM card, you accidentally entered the unlock code 3 times and now the phone won't turn on. Hopefully they can provide a working solution.

[Q] how to update an "unlocked" phone

complicated story. recently purchased an "unlocked" optimus 7 phone off of kijiji and it was working on my fido simcard, but it only worked until i got home and synced with my computer played around with the simcard and battery and was alittle rough with it, then the "unlocked" phone detects no sim on my phone. had a feeling i got ripped off. but awkward enough i think i had a hand in making it not work (i tried putting the sim card in without pulling out the battery, so i suspected that i might have messed up the hardware)
few days later, plan was up for fido so i switched to telus, but because the plan i got did not include data, so i am not sure if it would actually connect with a "unlocked" telus phone, i just want confirmation from anybody that "Any sim card can work with Any telus phone?"
story aint over
hoping that it was my fault for only messing up with the software by attempting to unlock myself and that it had nothing to the hardware, i went to pacificmall to somebody reliable to solve my problem and asked to "re-unlock" it for me.
result was that he told me it might be a hardware issue, and that he tried other sim cards and phone had not detected any signal.
what happened later on was i attempted to fix hardware my self by looking to push the simcard holder down thinking that it might be because it was loose from be trying to jam the simcard in earlier.
end result, phone is now detecting my telus simcard, and so my main question now is "i dont know if its becuase it is unlocked that made it work, or do all telus sims work on all telus phones and i fixed my phone by some retarded method"
All Telus sims work on all Telus branded phones, no matter what you may have done to it.
not working anymore
after having reception for one day, it ain't working anymore.
can anyone provide any help? would it be a good idea to sent it to Lg for fix?
Dude, I don't know for sure, but you probably did a short-circuit on the SIM socket when you tried to insert the SIM with the battery connected =/

Urgent AT&T network problem: Atrix 4G Android

I am urgently in need of someone who can solve this network problem I have been having. Right now I can not access any mobile network with this phone.
I am using an Atrix 4g unlocked and rooted.
Basically, my problem is that my phone has been asking me for a "SIM network unlock PIN" every since my time in Italy.
I recently went to Italy 2 weeks ago, and came back yesterday. On my first day in Italy I bought an Italian SIM card from the Mobile Network company Tre, a company similar to AT&T. When I replaced my AT&T network card with the Tre one, it asked for the SIM network unlock pin. Seeing that I did not have a code on me at the time, and after trying several numbers given to my by Tre, I replaced the tre card with my original AT&T SIM card. I later learned that my phone was not international and I unfortunately did not call AT&T ahead to unlock it, causing the phone to lock network access. I learned that this is a security feature in case your phone is stolen.
I'm asking for your help because I spent literally over an hour with tier one and tier two support of both AT&T and Motorola technical support all telling me the same BS.
Before calling any support numbers, I went to an AT&T branch, and I told them the situation. They replaced my AT&T SIM card with a new one, yet the phone still asked for the SIM network unlock PIN. They then told me to call support and ask them about a subsidy unlock code. AT&T phone support gave me multiple codes to unlock the phone, but none of them worked. All of the SIM and IMEP numbers on the phone were correct in their systems too. After telling me exactly the same thing as tier 1 support, AT&T tier 2 then transferred me to common Motorola support tier 1 support. Motorola only told me to hard reset the phone, which I do multiple times every time I update your firmware anyway. The last hard reset I did to my device was literally 30 minutes before I called technical support. They then told me that the only thing I could do is to replace the phone under warranty with either motorola or AT&T.
However, I am in a pickel becuase my phone is completly unlocked, rooted, has CFW/kernel, etc...and I think that wards the warranty.
I have been using this same firmware ever since I got this phone during the last summer, and it has been working perfectly. After I put in the Italian SIM card, the network locks. I have no where else to turn but to an expert here on xda.
Is there anything I can do? The only thing I can think of is to tell my story to a nonobservant AT&T guy over at a store and ask him to replace it. However, I don't know what would happen if they found out my phone is unlocked and they gave me a new phone under warranty before realizing this...
Thanks

Ahh, perm SIM locked.
Pretty sure that has to go back to the manufacturer to be fixed, if it can be fixed at all.
Just go ask for a replacement, they shouldn't be able to unlock it anyways.

thanks for the reply.
However, two things:
1) I thought it might be permanent, but I was not sure. Back in Italy I remember the phone giving me a certain number of try's, so I now that I think of it I might have exceeded that, causing it to perm lock. Is there any other way in telling if it's perm locked?
2) Also, one of my concerns is that AT&T will see that my phone is unlocked and rooted and all of that, thus warding the warranty and the replacement. I'm thinking that maybe after I give them this phone and I get a new one, they look at the old phone in the future and will see that its rooted and unlocked. Is this possible or what?

1) Just putting your sim card in and having the phone not respond pretty much sums up the sim lock.
2) I would at least revert the phone back to stock. AFAIK, unlocking the bootloader burned some sort of efuse so returning it back to a true factory state is "technically" impossible, but I do remember seeing that you could at least relock(?) and removed the unlocked notification at boot. I believe you should still be able to access the phone even when the sim has been locked, just start it without a sim card in place. If you can bring it back to an AT&T build, I think you'll be okay if you're still under warranty.
Just remember that next time you travel, either have an unlocked GSM phone or get a sim subsidy code from the carrier that the phone is linked to.
Would getting a code from cellunlock.net work? Or is their code the same as the ones given to me by AT&T tech support?
AT&T tech support gave me three '8 digit numbers', which were randomly generated. None of those worked. DO you think a cellunlock number would work?
Also, I am reading up on some forums saying that people in my situation (who's phone does not accept any SIM card and still askes for the code), can get the phone to accept some codes by reverting to stock firmware and radio. This is by .sbf though....
If things haven't changed, I believe the sim subsidy unlock would only clear the phone for the next foreign sim card placed in the phone whereas a real unlock code would completely unlock the code. Once your phone has been locked though, I don't think that code will be of use anymore.
It wouldn't hurt to try to sbf back to a stock build provided you follow the proper instructions to not get the x1000 hard bricks. Aside from trying that, I would think your best bet would be to just get the phone exchanged under warranty.

SIM lock
Looks like you have locked your SIM. Since you have rooted your phone you voided your warranty , best bet is look for SIM unlock code from online probably ebay will give you cheaper options, try them if worked great if not then there is a tool to root/unroot any android device, I will post the download link once i find. restore the device to factory settings if it permits and unroot back . then claim for replacement.
Hi i just unlock my device after hours of investigation. You have to change the baseband. Here is what you have to do. Flash the baseband to the ones from brazil (search in google sbf not the zip ones), after the process you can put it back to the usa at&t radio. Ones you change to tha brazil radio (wipe always before changes radio), put one sim card of another provider and voila, the code will work. You need to have your phone with no registration of motoblur at all.
I hope it will help you.

Hey this metod works with an lg p930 too?

one Samsung Galaxy S4 EE sim says 'invalid sim other OK

I have 2 Galaxy S4 i9505 phones.
Phone 1. Bought as used phone on Ebay and was previously locked to the 'Three' network, I had it unlocked by 'Three'. This phone has always, and still does work without problem with my EE 4G (pay monthly) sim. The only remarkable thing about this phone is that it failed/froze/bricked whilst installing the Lollipop upgrade. It was repaired - new boards - under warranty in April 2015.
Phone 2 was also bought as used on Ebay. This phone had been used on O2 network. I discovered that it had never been locked to any network. I bought a pay monthly 30 day rolling contract thinking that it had been locked to O2. When I put my EE 4G sim in I got the message 'no sim, insert sim'. Baffled. The only thing I thought could be the problem was the sim itself, EE gave me a new sim. The only physical difference this sim had was that it had the Nano option. When I put this sim in phone 1 it worked perfectly, I put it into phone 2 and it worked! I needed to put the sim back into phone 1 to set it up to transfer data. When I put it back into phone 2 the message 'invalid sim' came up and that is where things stand.
As I have two phones I was hoping someone could guide me through the necessary steps to find out where the problem lies by comparing the two, and hopefully find a solution. I have read another thread from tomedwards93 posted in April 2015 and see no solution was found by him so maybe this could help him too.
Can someone please help?
I didn't understand a single of what is written,the description is long and read this thread twice,still can't a understand this thread

I've replaced the sim card slot and done a factory reset, it worked for about half an hour then the 'No sim ' message returned. It still works with a PAYG '3 network' sim, with intermittent 'sim removed restart phone' message I no longer have the O2 account.
I have another fully functioning S4. Can anyone guide me through comparing the Android settings on the 2 phones.
I've never attempted either flashing or rooting and don't understand how to go about doing this.
Just to say thanks for the suggestions, the phone has now corrupted my SD card and I've had enough, I'm defeated. I'll keep this phone as a Sonos controller and go to Lumia 950 on Win phone 10 when it arrives.:good:
Sim not detected
I have a samsung S4 i 9505 and I often receive a message "insert cart sim". After rebooting it works normally
