So I posted this on the general android help section but didn't get much help so I'll post here too:
Hi everyone, I have an LG Optimus G (F180K) and I've been using it fine for the last couple years and most recently under the V30D firmware which is KitKat 4.4.2. I've flashed CM11 and MIUI on it previously but restored it to the stock rom several months ago and have stuck with it since. About a week ago I flashed MIUI again as it seemed there were new builds avaliable. The installation went fine but when the phone booted up I realized I didn't have any service and my service provider was not being recognized as it just said "No service". It did show there was a SIM card inside though. So using CWM backup I restored back to my original stock rom and realized there was still no service so I did a clean factory reset. That didn't fix the problem so I tried updating the phone with the kdz files straight from LG's servers which still didn't fix the problem. I checked my IMEI which was not broken and the phone number of my SIM card is recognized but it just always "No service". I tried reverting back to stock rom and factory reset multiple times the past week but it still won't work. Any help? Thanks
So basically I have a rooted F180K that won't get service despite a clean IMEI and reverting back to stock rom.
i have the same problem but in a 977, i did it all but keeps the same searching for network
Try this with terminal emulation app or adb shell. (You must be rooted!)
If you have problem with sqlite3 command you can download and install with Play Store.
Code:
su
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE global SET value = '10' WHERE name = 'preferred_network_mode';"
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE global SET value = '0' WHERE name = 'subscription_mode';"
i did it, but i only get gsm network, i can't get 3g, i restore my efs bkup, my modem but keep the same, only gsm
--------------------------------
Flash my carrier kdz, but keep the same, i dont know what's wrong, only gsm, thas all i can get

Really not sure what to do here, and I'm starting to get very frustrated, especially since I know exactly what the issue is and I can't find a solution... So here is everything I did up to this point in detail. I wanted to go back to stock for a while, but I remembered not being able to update at all last time I tried this. I used the LG Flash Tool to go back to 10b (I think? Earliest firmware out there) It started when my phone would tell me that "My Device was not registered yet" in the System Update settings. I did some Googling and found out it was because my IMEI number was blanked out (All zeroes), and I found a tutorial that was for the G2, but worked for the G3, to repair the IMEI. I first rooted with the LG One Click Root Tool when I got to Lollipop, used the IMEI that was under my battery, converted it to HEX and injected it into my phone with RF_NV_Manager, which was installed with QPST by Quallcom. After doing this, my IMEI was fixed, it matched the same IMEI that was under the battery on my phone, though I never texted or called anyone from there so I never noticed anything strange. I was able to update to the latest official Lollipop firmware, but then my phone started telling me I left the home network. Thinking it was just a glitch or something, because I had roaming issues before on stock, I switched to a custom ROM since that fixed it last time before I even knew that IMEI's existed. That didn't fix it at all. I was on LiquidSmooth Alpha and my phone will still go to roaming, and the way I would fix it was to piss around with the mobile network settings and change them back, then I would get 4G LTE for a few minutes, but I would NEVER be able to call or text. Since it was a discontinued ROM, I thought I just got unlucky, so I went to an official Nightly for CM12.1. At the moment I have LTE but no calling or texting... Then I found out that these issues tend to occur after IMEI fixes, so what do I do? Can anyone point me to a proper tutorial on how to fix this? After looking, I ended up downloading and installing something called EFS Professional 2.1 but now I'm even more confused...
EDIT: I tried going into ADB and inputting "adb reboot nvrestore" but that didn't fix it... The site said it's based on a backup that was automatically created when the phone was first built but that was on a completely different forum for a different phone. Going to try to flash back to stock KitKat.
EDIT: Alrighty! I'm getting somewhere! I flashed back to 10B with the Upgrade DL option, before I used Board DL. I can call and text now, as well as LTE, and OTA updates work, but I'm just going to root and go straight to the Nightly CM12.1 that I wanted to go to in the first place.
EDIT3: That seems to have done the trick. For people who have had issues with roaming after IMEI repairs, try flashing your stock TOT with the Upgrade DL option, then root and install your preferred ROM.
Okay so i have the T-Mobile Galaxy s3. It has been rooted for a while with zero problems. I got tired of the older android on it and decided to install a rom. I installed Cyanogenmod 13.0-20151208-unofficial-d2tmo running android 6.0.1. When i first got it all booted and loaded with gapps, i noticed that it recognized my sim and that i had a signal but i couldn't use any LTE or just all around data. basically i couldn't go online (in case i just didn't explain that well enough. Phone service is a mystery to me). I did some searching online and found a lot of people saying that i needed to update my baseband. i found a baseband for my model (T999) and tried to flash it in TWRM. Once i rebooted, it said "No SIM card - No service." in the upper left-hand side. i have tried flashing multiple different basebands the same way with no luck. i tried backing up my EFS folder and the restoring it because someone said to do that and that just... just no... it didn't do anything. even Odin 3 said it was a "FAIL!". So here i am with this android equivalent to an Ipod and i hate this. Everything else in this ROM works perfectly aside from this but this is a super big problem. PLEASE HELP!!!! A phone isn't a phone if you cant even send a text.
Did you update the phone's bootloader and modem to the latest version before flashing CM?
hello,
I have installed a custom rom onto my lg g3 d852 model. But after many failed attempts to correct it, my phone will not stay conected to my mobile network. My phone is now running MM 6.0 on the koodo network. I believe that this problem may have started because of a setting I may have changed in the hidden menu.
Ive tried:
-downgrading back to LP
-Switching sim cards
-updating firmware
-checked the imei (still says its there)
Any help is greatly appreciated.
EDIT: I have found a temporary solution. I switched to HSPA only in network options, this got my phone connected back to the network at least for now. I would like to have access to all frequencies. Any suggestions?
Bump...
Which custom ROM did you install, and does the problem persist after a factory reset? If it's merely a setting you changed the restet will put it back to default. If it's a modem setting you changed in the hidden menu, a clean flash of the ROM will get you back to where you started.

I made a mistake, the rom is a stock rom MM of Koodo/Telus provider that I downloaded off of xda... I can link to the rom if necessary. I have factory reset several times and tried Fulmics LP and MM and this version I'm currently using getting the same results.
If I were in your shoes, I'd do one of two things. First, I'd try the nand back I made when I got the phone, before I'd flashed anything. If you don't have a good back up, one that includes the efs, modem and bootloader, then you need to revert to stock using the factory kdz image. There's a tutorial here http://forum.xda-developers.com/showthread.php?t=2785089
I shall give this tutorial a try. Thanks.
Update: I flashed ZV4 again, with Flashtool, and now have a baseband. The MEID is still changed. The phone went through the hands free activation successfully, but it doesn't show any other signs of activation (not really activated). I have the original MEID on the box if it helps. And I noticed my SPC comes back "000000" (I'm not sure if that's significant).
I just bought this phone, used and in really great condition.
What I did:
Flashed ZV4 Firmware
Flashed Resurrection Remix 7.1.1
Flashed back to ZV4 Firmware, because I forgot to activate my cellular, while on stock
Tried activating my cellular services to no avail (dialer codes, factory reset, profile, PRL)
Took an OTA to Lollipop (I was just frustratated, so I thought what the heck).
More attempts at activating cellular
Realized my MEID has changed, also phone number is now 000-000-8784 and baseband is unknown.
With help from a Redditor, flashed Barecee and then flashed the ZV4 modem, but baseband still unknown
What I can still do now (phone operates fine, besides cellular activation)
TWRP
Download mode
rooted
I don't have any backups. When flashing, I never wiped the internal storage or external storage.
I'm ready to do whatever I can, to get it fully functioning again.
