I had a problem with my korean version LG G2 (i messed up some system files and i was stuck at reboot), i had to reflash the original kdz system file, and then i had to hack the phone network, and doing this also fixed all the network connectivity problems i had previously, which i tough was hardware but apperently wasn't.
I had to make extended searches to restore my phone to a working state, so i wanted to create a small guide for anyone interested in completly resetting phone to original and change to international network, this might work with D802 or other models too, but i have no idea, so try at your own risks, i am sure it will work on all the korean versions of the LG G2
Before you start for safety make a complete back up of your system
but most important backup up your QCN and backup your modem.img modemst1.img and modemst2.img all three of them in a safe place, you might need them if you want to restore phone basebands to old state, and i highly reccomend you do.
Backup is a very important precaution, please don't make me responsible for lost stuff, your internal SD will be completly erased, so backup everything you need, this will wipe clean everything on your phone.
If you are interested in where to get kdz files
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
and write your phone IMEI after the = (found in settings or on the serial number of phone, under battery, korean version has battery removable)
Write down your imei because you are gonna need it again
Then to flash the kdz you can find tutorials on XDA
You should be on 4.4.2 when you are done (unless there is a 4.5 lollipop OTA in the future, finger crossed)
anyway after flashing frimware, the phone will only recognize branded SIM cards of the korean networks depending on what version you installed.
So if you want your phone to be international, and with all the sensors working and so on, you have to root the rom, install a recovery with autorec from cloudyfa
enter recovery and flash this http://pan.baidu.com/s/1jIe5o pass: us56
this is a link i found on a chinese forum, i downloaded the F320LSK_EDGE_V3.zip
after reboot give sometime for the mobile to find network, it will need 5minutes the first time, it did for me, after everything working perfectly
the only thing is your imei will be reset to 0
to fix this
http://www.droidviews.com/how-to-backup-and-restore-lost-imei-on-lg-g2/
the second part of this guide
I think this will help a lot of people with network problems, or those who have bricked and wasnt to restore the phone to a working state.
also after you are done you can install any rom you'd like, i'm on cloudyG3 and everything is flawless, just don't flash the baseband like reccomended, the proper baseband is the one i linked
I have no problems with wifi to 3G switching, i have no problem with 3G whatsover, there should be no problem also with 4G but i can't confirm that, haven't tried GPS extensivly yet, but it seems to be fine.
For what i can understand these files that you need to flash are the basebands of the 802 international model, so in theory this should fix problems for other models too, but i haven't tested, so do at your own risk
Thanks, so I have a an f320 ls, is it ok to flash the d802 baseband? I would like more bands for the US and possibly LTE. Thanks

Not really the baseband i linked is based on the D802 but is heavily modified to have it work on all F320 models, also if you flash this baseband it will erase your IMEI, and you if you flash other basebands that other devs post here on XDA they won't work.
It's working very good for me i have no complain, wifi 3G 4G and calls even roaming

Thank you for your information
Of all the stuff I googled, this is by far the page/site that provided the best and most helpful information. I will start the story by stating I am jealous of a friend of mine that has the LG G3. Seeing his Android Operating System made me drool. I wanted it. I rooted my phone and flashed the OptimusG3 v1.4.1 rom without making a backup of anything on my phone; no EFS backup, no IMEI backup, no modem/baseband backup, nothing. My previous experience rooting and flashing my HTC EVO gave me a false confidence in rooting the LG G2. When OptimusG3 booted I somehow lost the network, APNs, baseband; thus I couldn't make any phone calls, send text messages, or send or receive any internet data. My first reaction was to revert back to the stock firmware. I could not find a kdz file that matched my phone and would work; an LG G2 F320L on the LG U+ network in South Korea. I tried multiple versions of the LG Flash Tool to try and flash the stock firmware back on the phone. I eventually found a tot file that worked, but I ended up losing my IMEI in the process. I tried taking the phone to get repaired by LG techs and they couldn't figure out how to fix it. They wanted 281,000W, about $281, to fix the motherboard. I tried getting a replacement phone and the LG employees tried to get me to renew my contract and purchase a new phone and SIM card, around $480 for that route. I ended up buying an older LG F160L and placing my SIM card in that while I attempted to repair my phone.
On to the good stuff, the tot file got me to a working version of 4.4.2 Android but it was not stable and constantly rebooted, showed up with errors, no wifi, no keyboard. I found 4 different kdz files that were various versions of 4.2.2 and 4.4.2. It took me awhile to find a way to flash the kdz file properly. I used LG Flash Tool 2014 Build 03/07/2014. I had to change the Type to CDMA and Phone Mode to CS_EMERGENCY before doing a CSE Flash. With those settings I had 4.4.2 on the phone running F320L21V. I rooted the phone, flashed F320L_EDGE-4_42_V2 *AND* KK_Baseband_F320L, before using the above fix to restore the IMEI on the phone. As of right now the phone is on F320L21V, I can make and receive calls, send text messages, the wifi hotspot works, and I can send and receive internet data. However, there are still a few issues: knock-on doesn't work and in the notification bar it states there is a software update is available. Every time I install the update the phone boots into TWRP. I have to hit Advanced, Terminal Command, Select and enter in the following two commands in the shell to get it to boot:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
I have since made an EFS backup, backed up the modems, and made a TWRP backup. Is it safe for me to flash another rom? Should I try using the LGMobile Support Tool to restore the firmware to F320L21y, to which I'm sure there isn't a root method for?

Is this working with latest 30D Firmware Lollipop 5.0.1?
I was working great on Kitkat firmware but seems to be not working good on Latest 5.0.1.
If you have any new Mod like this for lollipop please share.
Hello, to both of you,
@AlphaQ99
You can safely flash clodyG3 and have a phone almost identical to the g3, that is the ROM I'm using, it's stable and looks fantastic, and I have decent battery also with original kernel.
It should remove the update requests and the other problems you are having, just don't flash the basebands that come separated from the ROM, keep the basebands posted in the OP, or reflash it if something doesn't work.
@Shivam Bhalla
You can try the edge v3 zip from the cloud baidu drive I posted in the OP?
Let me know if it works, I guess if it does let me know, because I want to flash the new update too, if not let me know too so I won't flash it...
If it doesn't work just download a 4.4 or 4.2 kdz and then flash the modified basebands and whatever ROM you'd like over that, I reccomend cloudyG3 if you want a G3 look.
And restore your imei with the OP instructions.
If the v3 doesnt work when there will be a lollipop version it will be posted in that drive in the OP.
I think we'd better wait still for updating to lollipop kdz or roms, I myself will attempt the update just after the clodyg3 ROM will be updated, and that will take sometimes, since they are waiting for a D803 official update...
Best of luck to both of you
I tried to flash CloudyG3, Optimus G, and CloudyFlex 2.7 all for the F320L. All of them did not work properly. I had data, I couldn't make phone calls or send text messages. I think the APN settings were incorrect and I tried changing the settings to match LG U+ and tried to change the build.prop file. They all made the com.android.phone cause a force close. To fix the knock on/off I had to go to the dialer, hit 3845#*320# > HW Device Test > Touch Test > Touch Firmware Upgrade.
I ended up going back to stock using the kdz file in this post and I'm having fun with lollipop: http://forum.xda-developers.com/showpost.php?p=58206425&postcount=1
You flashed lollipop and everything is working fine?
You are using my basebands?
Or was it unlocked already?
I simply flashed the stock kdz file and everything is working fine. I lost root which at this point I am fine with.

I see but you are using a U+ Sim?
Like the one ur phone is locked with?
Yes, I am using a U+ SIM card.
Sent from my LG-F320L using XDA Free mobile app
Then everything should have worked with the other kdz too, the problem is I'm not using a U+ Sim so I need to unlock the network, for that I probably need root, and a recovery, so I'll wait, unless the other guy can figure it out...
I'm happy everything turned out OK for you, how is lollipop? Worth the update?
I like lollipop. It's something fresh and new. I was really tired of the old keyboard and the UI was getting stale. I just wanted something new and different. Lollipop has been working flawlessly and had it come out two weeks ago I would probably wouldn't have bothered with rooting the phone to begin with. For some people it wouldn't be worth updating because I'm pretty sure there isn't a root method for it yet. For someone who doesn't care much about rooting the phone it would be worth it. When I get tired of lollipop I'm sure I'll be back on here looking for root options.

Are you still on Kitkat or using Lollipop???
These basebands are not working on lollipop and because of which I couldnt able to have taste of stock lollipop roms.
Networks works good in 30E latest firmware but not a single sensor is working after flashing this basebands on latest firmware.
If you got any solution for new basebands do share with us.
No lollipop baseband that i know of sorry....

Hey guys !!! I fixed the network on Android 5.0 (f320l)
I am from Kazakhstan, and do not speak English use a translator .... so sorry.
1) First you need to install stock rom (I used f320l21y_00.kdz) (LG Flash Tool 2014)
2) Install Root (I used Stump-v1.2.0.apk)
3) Install Recovery (I used F320L_AutoRec.apk)
4) Then you need extract TWRP.rar to Internal Storage
5) Reboot to TWRP and tap to "Restore" => 2014-12-06--02-11-08 KOT49I => swipe to restore => Reboot (decided sim card)
6) Restore IMEI (post 1)
7) Then i install CloudyG2_3.0 (5.0) and I have all worked on Android 5.0
TWRP.rar can use for f320l and f320k (f320s not sure, but you can try)
Good luck!
Sorry for my English ....

Hi guys, first post here so please bear with me.
I recently bought a used LG G2, its the Sprint model from the USA. The previous owner had it rooted, and flashed a stock T-Mobile rom or might have been a custom T-Mobile rom.... needless to say, the model of the phone changed to D801 (the T-Mobile Variant).
So when I use LGFLASHTOOL to flash the Sprint *.tot file, it gives me an error message stating that the hardware model does not match the software I am trying to install, because the phone basically now thinks its a D801. The phone, however is the LS980 from Sprint. As well, *#06# is giving me a "null" IMEI. The previous owner never gave me the box ,so I don't even know the IMEI number for the phone. I'm really frustrated having bought the phone and now can't even use the stock firmware. Does anyone know how I can put the sprint firmware back on using the kdz method ? Or perhaps how I can override LGFLASHTOOL to flash the Sprint *.tot without it checking the hardware.
Please help, I'm out a lot of money if I can't figure this out. BTW the phone is no longer rooted, and keeps resetting itself. I had reflashed the stock T-Mobile rom because he told me it was tmobile (really was his own custom t-mobile rom) so now i dont even have TWRP on or root.
Again, the phone constantly turns on and off and I'm desperately seeking help. Thanks in advance.
P.S. Also wondering if its impossible to know imei if it says null.... but restoring the Sprint rom is my main priority.
Do you have access to recovery like twrp? If so, just flash a sprint Rom, any rom. That way the next time you use LGFlashTool it will detect it as a LS980.
Edit: I see that you don't have twrp. ..

Any update OP?
Were you able to fix this? I have the same issue.
I tried to install the new version of CyanogenMod Snapshop but unfortunately afte the reboot of my LG G2 D802 the mobile phone bricked.
I read a lot around the Internet and finaly i succeeded to unbrick it. Th problem now is that i do not have IMEI (is null now). I read that there is one program that you can fix your disappeared IMEI but cannot work in my personal laptop. Do you know anything how to repair and fix my IMEI with my previous official IMEI (i have it in the box that i bought but i didnt have any backup of it).
Thank you
I am having the same problem. I was loading a milestone version of a rom and when it loaded after wiping there was no service whatsoever and everything is null. I understand it wiped the efs and I dont have a backup. I also understand that we can change the info back with the numbers off of the original box using dfa cdma tools. I have the program but my question is the 000000 code does not work when i try to unlock the phone. Anyone with any experience with this program that can help me to re write my meid???

Dfs CDMA tools
I don't have any personal experience with this, but I have done a ton of reading on this problem and it's become my biggest fear. From what I have gathered you have very very little chance of fixing this yourself. It most cases it goes back to the manufacturer. Can you tell us exactly how this happen?
I have no idea, i have been rooted for months and swapped roms like crazy. I wiped and installed a new rom and then it was getting no service so i tried to update profile and said it couldnt. Then check in the settings for the baseband and meid and unknown was shown across the board. Trying to figure it all out now!
I have had the same thing happen what cm did u install I had a d802 version on my ls980 restored it but now it will only accept a d802 modem and the signal is weak and drops out but it did show my ESN and imei and baseband again instead of unknown if I would have flashed it with a ls980 modem

Have you tried restoring a backup?
Sent from my dr87 v7 powered, Mahdified LG G2 (D801)
My problem started when I tried to update my LG G2 D8002 to the latest Cyanogenmod Kitkat Snapshop and i stuck in clockworkmod recovery loop after returning in CWM to take backup. I tried to connect it to my Laptop but i cannot have any access in my files via my laptop. The bad thing that i did is that i formated everything in my mobile (as you can see and my IMEI too) to make a clear installation of a new rom after the brick. When i entered my new ROM i realized that i have everything apart from my IMEI. So that i do not have any network-signal in my mobile but a connection to Wifi
The program Dfs CDMA tools and Octopus Box does not work in my desktop. (Any idea?)
Do you have any idea how to repair it? I read that there is a folder (nfs i suppose that encode inside the IMEI). So, if someone find this folder can upload it somewhere? Probably will find a solution to solve it.
i was solved problem with no imei :
make full buckup from TWRC in another LS980
restored that buckup in bricked phone (make first buckup on it, to know name of folder, and take to that folder buckup from work phone)

Are you sure that this works in all devices of LG G2?
Hey,
anyone here with a ZTE Blade L6 and a running (stock) rom? I bricked mine using some chinese adware-root. After flashing a described as "stock" rom firmware image, i had the phone up and running, branded and netlocked by Digicel. With a little dirty work i now have it mostly unbranded and with another modem even online.
Now, my problem is the modem/baseband. Some give me emergency-calls and a working data connection (but only GPRS/Edge), some even the ability to make phone calls. BUT: I never got back the 3g/wcdma. The Mediatek Engineering-Mode tells me, its using the bands 850/2000(2100), 900 is grayed. As i am in Germany, this should be the issue.
Is anybody in here, who has a working L6 rom or knows how to unlock the wcdma-900 band?
My NVRAM doesnt seem to be changed, my IMEIs are still there..
Thanks in advance!
"Even if it was unlocked, your antenna wont do it!" isnt the right answer, it did before so why shouldnt it now? And its just 50 Mhz..
Same here, I need the real stock ROM or a working C-ROM for the ZTE Blade L6, not the Digicel FW. My phone has been "SIM-slot is permanently locked" after inserted a Sim Card which wasnt supposed for this ROM/Provider, it seems.
I would appreciate it if someone has the S- or C-ROM or knows how to unlock the permanently locked slot again. OEM Bootload unlock (via ADB - I needed to confirm the OEM unlocking with the Powerbutton on the phone but it doesnt react) and ReInstalling the Digi-ROM wasnt helpful.
I unlocked mine using the modem of the L5 Plus-rom. The modem goes to emergency mode every few minutes and data isnt working good too (no 3g, even though i fixed the bandmode somehow), but it gives you a little bit connectivity.
Just grab the L5-Rom, mount the system-images of the digicel-l6-rom and the l5 and replace the modem in /etc/firmware with the l5-one.
You can flash the L5-system too (only system, nothing else!, at least NOT the boot.img). But for me it shows a data connection but cant use it..

Like said, doesnt work properly. :/ Crashes and disconnect. Well, it´s just my fun-phone to test out some roms and recovs, so it´s not that important.
Ok, since I´ve managed to revive my "playphone", I´ve made a fastboot-flashable nandroid backup. It includes also i.a. a custom recovery from TWRP in an extra-folder.

Somehow or another I have managed to screw up my modem on my SPerry XT1766 (Boost Mobile).
I only get Emergency Calls Only radio signal, Settings app and bootloader info shows Baseband Not Found or Unknown.
I tried using RSDLite to flash
XT1766_SPERRY_SPRINT_7.1.1_NCQS26.69-64-10_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC
which contains the fsg.mbn and NON-HLOS.bin files, but this doesn't seem to help. I've tried multiple firmwares with multiple different modems and nothing seems to be getting my modem up and going. Back when I originally updated I flashed the partition updater also. I have no idea what to do now. I'm downloading the 69-56 version to try that, but I doubt it'll be any different. If anyone has any idea on what to do that would be great. Thanks

Try my baseband updater from this thread. https://forum.xda-developers.com/mo.../rom-stock-android-7-1-1-rom-moto-e4-t3885821
It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.

Yeah I already tried that but it jept giving me an error saying unknown command [ ]] or somrthing along those lines. i looked through the script and didnt see any typis. i think your NON-HLOS.img is different format than the NON-HLOS.bin files found in the stock firmwares, plus it's much larger. Anyways, tried a fastboot flash the modem with it and that didnt work either.

No I am not on a boost network but this problem goes more into firmware than network compatibility because the bootloadet itself isnt even recognizing the baseband. For the record I am still using a CDMA network like boost (Verizon)
Also as an update, the 56 version didn't fix it either

The latest update did that too many people. It won't work with a different sim. The radio will be off.
I bet if you put in a boost SIM, it would pop right on.
They changed something in the -8 firmware.
One guy building ROMs (not here anymore) made some changes to his build that got certain networks to work on his ROM.
He never got the chance to share exactly what he was changing.
It seems that if you booted the phone ever with the original sim inserted, it tripped a qfuse (of sorts) and it seems they have added a way for that particular reading to turn off the radio completely if you're not using one of their SIMs.

You are 100% on point. Sprint (and its subsidiaries) had Motorola Mobility to include code in an OTA update which would disable functionality of any network other than the original UICC (SIM). In other words, when you got a new Sprint compatible xt1766 (Sprint, Boost or Virgin Mobile), opened the box and booted the device with the preinstalled SIM in it, the xt1766 became forever locked to that network -- the OTA update carved that in stone. The update made it impossible to downgrade the baseband radio, killed all GSM functionality, and broke the radio on custom ROMs (the latter being unintended most likely). The only people I have heard of getting around this are the ones that didn't take the -8 OTA update. Like you were saying, I'd like to know what Jason M. done in his custom ROM to fix radio function, whereas at least the radio would work with the original SIM on a custom ROM. He said something about "adding missing symlinks" to the build.
I did this too somehow. I think this might bring your baseband back (it did for me), but... well, I'll get to the "but..." Anyway, Boot to TWRP, mount the Persist partition, then go to terminal or pull up an ADB shell and do:
chmod 0700 /persist/rfs/msm/mpss/datablock/id_00

Reboot with a SIM card inserted and voila, you maybe might have a baseband again. Hooray! Except in my particular case, I regained a baseband and then somehow lost an IMEI. Well, not really "lost," it's still there when I pull up the barcodes page... but on bootup it thinks it's 000000000000001. I still haven't ever fixed it, though I did manage to turn it to a single 0 somewhere along the line. Fkit.
But I don't know of anyone else who's lost their IMEI this way, and it's been too long ago and I've tried way too many failed fixes to remember what else could have triggered the problem to start with, so who knows. If you decide to try it, definitely make a backup of the Persist partition before you do anything...and make sure your backup turns out to be good first, not corrupt like mine turned out to be....sigh.

Try my baseband updater from this thread. https://forum.xda-developers.com/mo.../rom-stock-android-7-1-1-rom-moto-e4-t3885821
It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.

Hello XDA,
I recently purchased a H910 from EBAY.
I was able to install Oreo and root it using the excellent tutorials before I was able to have a working sim card on hand so I cannot confirm if this phone was good or bad as I received it. I am using an activated ATT sim card and have used it in another phone with calls, texts, and data working. I have not for the life of me been able to get the any of these features to work on the H910. I have checked the APN settings, I have confirmed both the IMEI number and the sim ID number with ATT. The H910 is able to see the sim card but no mobile network is connected. I can use wifi calling and texting.
I did make a backup/dump of the phone and have flashed the modems, fsg, and misc images with no effect.
I have tried to restore to a stock image of 10q and 20G with the results ending in boot loops so I have not been able to test the stock firmware.
Is there any way to test for a hardware fault?
I would like to avoid returning this phone for something that could be fixed on my end.
Any advice would be greatly appreciated.

What APN are you using ?

This sounds like a hardware failure

are you sure the roms are flashing correctly ? no errors in TWRP ?
I have restored many times with those 2 files and never had a bootloop, flash the 10q or 20G rom then format data before you reboot

Ive had nothing but great luck getting phones off ebay, but it really sounds like you may have gotten a lemon.
The H910v20 is one of the easiest phones to root and return to stock the 20G rom should work and immediately ask to update to 20H with a AT&T sim in it.
taking the 20G to 20H update will insure you have all the correct modem files and APN.

clsA, Thank you for taking the time to reply, and for your excellent tutorials.
I tried both the stock(default) APN and manually entering the nxtgenphone APN info I was prompted by ATT but no change. Searches for a signal for about 30 seconds and the throws an x over the signal bars. The phone does detect the sim card and shows my phone number.
I do think it is hardware failure. All of the modem problems I have read have an error saying that the radio is off. I do not get this I get a message stating out of service. I also copied the Modem files from another stock H910 20H from a friend and that did not change anything. Their phone also shows signal bars even when the sim card is removed.
I checked the MD5 Hashes and they are correct on the SD card I was using. I saw no errors in TWRP and I tried 3 different flashing combos with both 10q and 20H. The first was to format device and then advance wipe system, cache, and dalvik, then flash, followed by format device. I then tried just format before and format after flashing, and then not formatting before and only formatting after and got the same boot loops with the 3 combos depending on whether I was using 10q or 20g. ie 2 different boot loops with the different zips. Once the boot loop started I could get to the stock recovery to "erase" the phone but that had no change. The only way I found to stop the loops was to flash the 996.kdz file using lgup and start over. The 20H file works perfectly. as does the 10R. It is really odd.
