HELLO! This is my first XDA post, although I've known about it for many years, I never bothered to Log-in and at least participate in the comments part as I always had problems with the login part, finally managed somehow to get into my account.
Anyways, I recently encountered a strange problem with my phone, after about 1 year of use on the same network carrier and after an upgrade from stock rom to Lineage 7.2, and about 5-6 months of working perfectly fine, yesterday after a shutdown due to low battery, my phone started to ask for a Network Unlock Pin and made my phone unusable since I don't have signal and it sometimes shows that my SIM is missing.
I tried installing a new Rom because I thought it would fix it but it didn't, so I was wondering if anyone here has an idea what might have caused it and how to fix this ?! Would really appreciate any kind of help, since I still love my Mini and wouldn't wanna quit on it, Thanks !!
My current plan is to go back to the original Firmware, I'll see what I can find on the internet.
Model : SM-G800M
FCC ID : A3LSNG800M
SSN : G800MGSMH
IMEI : 355680/06/021555/5
S/N : R28FA16C648 14.10
BTW, I live in europe, Romania.

Hello,
I've been come to xda-developes site a number of times over the past couple of years and have always managed to work my way through just about every issue I've encountered...until now
This is my very first time posting, so please bear with me if my terminology is wrong or if I'm not really clear on anything
I got this Unlocked LG Thrill P925 for my husband from someone off of Craigslist. He loved the phone and used it for several months before encountering this issue. When I got the phone it was already unlocked. Although I didn't spend a whole lot of time digging around in his phone, I kind of assumed it was probably factory unlocked because I never saw SuperUser or any other typical app you'd normally see on a rooted/unlocked phone. Considering it is an AT&T phone and we'd been using it on T-Mobile, I definitely know it was unlocked lol.
As stated, everything was fine for several months. One day, my husband was having some issues with the phone not working properly. He finally removed the battery for a while then put the battery back in and turned it on. He said when it came on it had a bunch of computer type code (like letters/numbers/characters) flashing across the screen. One day I decided to mess with it and I finally got it to boot up, however, the phone is NO LONGER UNLOCKED. It seemed like it had basically just factory reset itself or something. I quickly found the battery would drain VERY QUICKLY. Because of this, I was really hoping that maybe the battery crapped out and caused the phone to have some sort of meltdown.
I got a new battery for it, unfortunately the new battery didn't help anything.
I started fiddling around with the phone and realized SEVERAL issues that I haven't been able to figure out how to work around (I've found posts of other people having very similar issues, however, it seems there phones were apparently rooted/modded etc...I have nothing that points me to believe this phone is rooted).
When I go to Settings/About Phone it shows the Model Number as LG-P925
Android Version: 2.3.5
Baseband Version: L6260_MODEM_SIC_01.1042.00
Kernal Version: 2.6.35.7+
Build number: GRJ90
Software Version: LGP925-V20p-FEB-22-2012
If I click on Software Update, I get a pop up that says "The application com.lge.omadmclient (process com.lge.omadmclient) has stopped unexpectedly. Please try again" and I have to Force Close it
If I go to Settings/About Phone/Status it shows
My Phone Number: Unknown <I do not have an active at&t sim only T-Mobile and it won't register>
Network: Unknown
Signal Strength: 0 dBm 0 asu
Mobile Network Type: Unknown
Service State: Out of Service
Roaming: Not Roaming
Mobile Network State: Disconnected
IMEI: Unknown
IMEI SV: Unknown
Usually when I shut the phone off **OR** if I try to do a Hard Reset (Hold Volume & Power Button down etc) the phone WILL NOT boot back up until I connect it to the USB again as if I'm charging it...even then I sometimes have to mess with it by taking the battery out, put it back in, plug the usb in THEN start it. Most of the time it will not start up without the usb being plugged in.
I have LG Mobile Tool...Occasionally it detects the phone and shows there's a software update available. However, when I try to update it, it either just hangs up at apprx 4% OR it will go into Emergency Mode and want me to enter the IMEI. Everytime I try to enter the IMEI # the numbers disappear before I can click next and it prompts me again to enter the IMEI #. ***Also..FYI...if I try to obtain the IMEI # by using *#060# I get a pop up that says Reorganinzing Internal Processes Please Try Again in a Short While***
I apologize in advance if my post seems long winded...I just want to make sure I give all the possible details I can...I'm a techy person, I really like working on phones etc and I've taught myself everything I know so far. Yes, I'd like to get the phone working again, however, I also want to BEAT THIS CHALLENGE....IT'S DRIVING ME CRAZY
Thank you for any help you can give me!
Somehow you lost IMEI. If the phone had an invalid or stolen one, I am unsure how to deal with that. Sometimes flashing firmware will also fix IMEI.

Otherwise there are guides for fixing just IMEI. Check Optimus 3D section (same phone, Euro version).

Thank you so much for your response. I looked over the link you gave me, in fact I found that thread before posting myself.
What I'm confused on and not sure how to proceed is that #1 it says must have ics...I only have gingerbread and so far have been unsuccessful in installing any updates/upgrades. I honestly don't even know where to start
I love android phones and am not a big fan of iPhones, however, I can jailbreak/unlock gsm iPhones no problem. I'm a bit more confused with flashing & rooting etc. I keep reading as much as possible, but embarassingly enough...I'm not even sure what process has to come first in this. Flash the from first? Attempt to root first? Or??? I can get wifi on the phone, but have not been able to install updates etc via the PC.
I'm sorry to be a pain...I want to be able t do this! I'm just stuck. I rooted/unlocked my galaxy s2 a coupe of years ago without issue, however, I really don't even remember all the steps I did with that. As much as I don't like iPhones, most of my family prefer iPhones over androids...which is why/how I learned to jailbreak and unlock them pretty easily. I've never ran into a problem like this where I have no imei etc. Therefore I am at a total loss on where to start given the current build and android version etc
Also, I forgot to mention in my initial post, I've read from some people that the apn could be the problem...I've tried going into the apn however, as soon as I click on apn it kicks me right out
It just means you can't install xbsall's custom ROM on top of GB; following the steps puts you to a rooted version of ICS, then the custom ROM, if you choose to install it.
Pretty sure IMEI should still appear even if APN is not set up, so I doubt that is the problem.

Thank you again for your response. I will give it a try later this afternoon and post the results.
It's just crazy...can't figure out how it could be working fine for months, then suddenly have a meltdown along with a case of severe amnesia lol. I've seen there's a lot of other people with pretty much the exact same issue...on the Thrill forum as well as the Optimus 3d.
Yeah, that is odd. We call that a 'glitch.' Who knows, maybe some startup process checked IMEI and didn't like it somehow. No telling... Hopefully it is not some hardware issue.
I bought a second hand GT-I9305. After the first boot I dicided I wanted to flash it with the CM nichtly. I first rooted the stock rom, flashed a recovery and then flashed CM. Now the problem is the I can't make calls. When I dial a number the phone responds with 'call ended' before it even starts.
I don't know if the phone worked to begin with, the first thing I did is flash it.
I've tried different roms now and reverted back to the 4.3 factory image. None of that fixed the problem. I've also tried putting to 2 or 3G only which didn't help either. My phone still shows an imei number.
I'm completely aware of the fact that I might have done something very stupid. I flashed android devices before but I'm the type of person who reads the manual when it's to late.
Does anyone have a suggestion on how to solve this problem?
I'm usint T-mobile on the EE network in the UK.
Problem still unsolved, more information
I'm giving some more information as the problem isn't solved yet.
I'm on a Pay as You Go sim that works fine in another phone (HTC Desire S). I've now also try to downgrade to 4.1.1 but still no luck. I've also tried different sims but the problem occurs with those sims as well.
The phone looks to be registered to the network, at least that's what it shows. Also, data works, I get a 3G and H+ connection,
I'm more than happy to provide more information. Any help is greatly appreciated.
SIM unlocked? Google xda sim unlock GT-i9305...
Phone not locked
Thanks for your reply. The phone is already unlocked.
IMEI blocked? If you're in UK try www.checkmend.com/uk/ it'll cost you 1.99 but might save you time & effort...
Hello. First of all, I searched the threads before posting to no avail. So if I'm being repetitive I apologize. But here's the problem. I have a t mobile galaxy note 5. Unlocked. It's rooted. Running an arter97 kernel, and Jovys Darkstalker kernel mod. Everything is running smoothly and has been for months. Recently the only problem is my signal. 90% of the time it is saying searching. When I make a call it says not registered on a network. This is strange because I have done nothing to cause this change. No new roms, mods, updates, nothing and it's been working fine all this time. I know it is not location related because it was working 100% fine from day one until now. I tried *#06# to see if my imei was null, it is not.
I let the phone search, and then choose an operator, that works temporarily giving me signal, but eventually goes back to, and stays searching. I tried to pull up the service menu using *#*#4636#*#* to reset the radio, but that number is not pulling up the menu. I was told I may have a bad efs, but I never created a backup because until now I never had this problem and didn't know efs existed . I don't know what my next step should be. Any help would be greatly appreciated!!!!!!
Sn: if there is already a solution to this problem on this forum send me a link please!
Try using the Shortcut Master (Lite) to pull up the service menu.
I've also got same issue.
My phone is n920c. I've spent all day trying fix this issue by new rom, but I didn't find solution yet.
Kind Regards,
Marcin

Where did you buy your phone? Why don't you check to see if it's blacklisted first (maybe it took a little while to get listed). Never ceases to amaze me the number of people selling stolen/balance owing phones, or the number of people buying them, for that matter:
http://www.t-mobile.com/VERIFYIMEI.ASPX
Very true. I think i may have solved the problem though. My phone was bought outright through tmobile. I try not to by second hand phones for that exact reason.
I think i have may have found my the solution. For me it was a sim card related issue. Apparently my sim card was exhausted, or had expired. This is why my phone kept dropping me from the network and i had to keep reconnecting. Accordind to t mobile your sim expires 90 days of no use. This dodnt apply to me but whatever. Got a new sim, transfered the number, problem solved. Also something else that greatly boosetd my service. Take the case off. This was why i got the searching status in low service areas and only 2 bars of service in good reception areas. Crazy that in 2015 cases still affect service but it did greatly. So yea my fix was a new sim and take the case off. Very elementary. But i can say it was not root, kernel related thank god :good:
Hello, my S5 mini has the first problems 1 year after bought, sometimes there was the error not registered on network. I have sent it twice to the support, but it was returned with "no error".
Now warranty over i have the error not registered on network, and can not use it for telefoning. The IMEI was correct, i can receive the network, but i can not register to it. I have the last marshmallow update flashed over OTA.
in former times, i have to remove the sim and reinsert it, to get it work again, but now this does not work. The simcard ist changed from the provider, and i bouhgt another simcard from another networkk, to test it.
Can i fix this problem?

Sam here, call me cynical but happened 6 months after phone ran out of warranty. Done all the basics, diff SIM from different provider reset phone, even re-flashed phone and no joy, tried all the modem software going and phone will only work on 2G. Samsung support said take it to repairers hmmm wonder what that's going to cost. New phone, New manufacturer I think. This is 2nd Samsung ive had issues with
I've only just got my first Android phone from a mate after obnoxiously using iPhones for years+, an S5 Mini that lags and ****s itself at every moment. I've now got a gangsaf little unit learning anything I can about this phone and after all my errors, not once have I seen this.
Just for relevancy, I have a G800Y model but I'm using one of the two kernels I could find that looked decent which the devs have listed under G800F and as far as I can tell or what I've read, there's no real difference other than a difference between the LTE bands they can access (someone please correct me if I'm wrong). If it would be so much as to ask what exactly is the software specifications of both of your devices? By this I mean:
- What ROM are you running; [Stock] or [Custom]?
- Have you rooted your device?
- Have you tried finding your device's most recent stock modem software?
- Did anything lead to this or is there anything you believe could have contributed to the occurence of such a problem?
- What carrier are you with in what location? If you do not wish to say for whatever reason, have you tried a search for devices with similar problems and a possible resolution method?
Hello, i have stock rom, IMEI is intact, not rooted,
Basisbandversion G800FXXU1CQB2
Kernel Version 3.4.39-895f4887
Buildnummer MMB29K.G800FXXU1CPL1
AP: G800FXXU1CPL1
CP: G800FXXU!CQB2
CSC: G800FDBT1CPL1
SIM-Card from Telekom or blau.de, both does not work.
I can receive the Providers, but can not connect.
My S5 Mini SM-G800F won't stay registered on a network, it registers initially but after a few seconds drops to 'Emergency calls only' with the notification that the selected network is unavailable. The signal strength is fine and the sim works in other phones. It's an unlocked phone, using a different network sim produces the same result. Bought it secondhand just over a month ago and it's been fine up to to a couple of days ago, done a hard factory reset but the issue remains.
Ideas for a fix?
This may or not be similar to an ongoing issue I have with my S5 Mini - See below :- Has your IMEI changed to the below at all - 350695200123951-01 ?
"Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !! "

No change to my IMEI, consensus seems to be that it's probably a faulty SIM card reader.
