LG G2 D802 permanently locked - G2 Q&A, Help & Troubleshooting

Hey guys, I've had an unlocked LG G2 D802 I used for 2 years, then I gave it to my sister, she uses it in different countries. It worked without problems in Greece, now she's in Italy, she tried to insert an Italian SIM card, but it doesn't recognize it. I told him to type 2945#*802# code in the dialer so she can check if there's a lock or something, now the phone says "This phone is permanently locked and cannot be unlocked". It shouldn't say that as it is factory unlocked, can anyone help me out in this? Thank you.

Close this, a new SIM solved it.

wipe data from factory reset or flash new firmware

[Q] L3 E400f ”This phone is permanently locked and cannot be unlocked”

Hi folks
This problem I have with this Australian L3 E400f is after I dial up 2945#*400# the unlock menu pops up as normal
selecting "network lock"
results in message "This phone is permanently locked and cannot be unlocked"
at no stage do I get a chance to input any unlock codes.
I gather there have been more than 10 failed attempts to input a NCK code, thou I am sure this is not the case it was straight out the box new.
the phone works just fine and dandy with all firmwares I have flashed as long as I have the telstra sim card in place.
I have used a Brazilian (V10D_00) stock firmware (using KDZ) hoping that the failed count lives in the firmware, it does not.
I have used CWM and flashed cynogen , this did nothing only the stock firmware allows 2945#*400#
gone back to my aussie V10D_00 telstra firmware and factory reset, then hardware reset..
I dont beleive this is a ROM issue. I am only guessing this is a EFS problem, anybody have any idea's if ADB or LGNSPT can get me out of this jam..
LGNSPT seems like a nightmare to get up and running and I have never used it before. I have once before on a samsung phone deleted the EFS folder (after backing up) and the phone generated a new EFS folder, I had my way with it then retsored the original EFS folder.
is their other methods of inputing the NCK code with ADB or else ?
thanks in advance this one has got me stumped...
all the best

[Q] Unlock a permanently locked D802

Hi guys, i hope you can help me with this one.
I bought a D802 from AliExpress, but when i tried entering my sim i found out it couldn't get any signal even though it works just fine on my nexus 4.
i tried 2945#*802# to check the sim unlock process and got the next message: "The phone is permanently locked and can not be unlocked".
I can't enter an unlock code even if i want to. It doesn't give me the option. i can only dismiss the message.
I tried factory reset, rom switching, and radio flashing, none of them worked.
I opened a dispute in Aliexpress, but in the meanwhile i want to try and unlock it anyway, and maybe save the trouble of buying a new one and wait for a month all over again.
Can anyone help and maybe knows how to bypass it?

[SM-G530M] SIM Locked after Firmware update

Hello, friends.
I do need your help.
I wanted to tell you that I had some problems with my phone's performance, so, after almost a year, I decided to upate its firmware.
* I've to mention that my SM-G530M was already SIM unlocked from seller/provider (Movistar Colombia).
* Also, all this time I've been using a SIM from Claro Argentina without any problem on that device.
I installed this firmware, using Odin (most of all, because I live now in Argentina):
--> G530MUBS1APE4_UUB1AOI1_ARO_Argentina_4.4.4.zip
When the process ended, it booted up normally, but after a reboot it started to ask me to put SIM network code.
* I've tried to flash different firmwares (Colombia, Argentina, Chile, etc.). With/without SIM card inserted.
* Also I've tried Factory Reset and Wipe cache (from software and recovery too).
* I even have tried to use "NAND erase all" in Odin, all in order to clean the most from the device to get prepared for a clean Firmware installation.
Unfortunately nothing worked.
I'm in ruins.
Please, friends, is there anyone who could guide me in order to unlock my phone again?
If you need more info, just tell me.
Thanks in advance!:
I know it's too old to reply, but at least I'll report that problem is solved forcefully, bands to other carriers had to be reopened. Unfortunately I don't know if the culprit of this SIM locking was the Claro's provider ROM I used, taking in mind it is the one I use in Argentina, but device was from another country. However this wasn't a case of international carrier restriction, since device was already unlocked, but this update broke it all.

K20 Pro Device Unlock error?

Hello. Im trying to use my old k20 on a new network. The doner sim card fuctions fine on 3 other teat devices. However it is not unlocking from Metropcs. Its been in my drawer for a while and can not find the original sim card. Whwn i insert working sim there is no Sim card detected. The Device Unlock app states both Pass and Fail.. What am i missing?
I have this message too, it basically is saying that the unlock fail because you (or somebody else) have already unlocked the device and have applied it. I just unlocked mine because I had forgot that I can so I can sell it, it worked and was approved, so it restarted and when I checked to see what it would say again, it gave me the "Unlock failed, Unlocked approved" message. In all, the phone is unlocked, but idk why it will still show the Metro PCS start up, aswell with all the bloat.

Unlocking the device doesn't automatically remove carrier bloatware and other signage. That's what the stock ROM for the phone will be like when it's bought as carrier locked.
As for the OP question, if the SIM works on other devices but not your K20, and you're sure it's carrier unlocked, have you tried doing a factory reset with the SIM card inserted beforehand? It may just be the stock ROM being stubborn or stuck with previous config data.

Network locked V35

Hi. I recently bought the LG V35 supposedly unlocked; however, I am unable to activate on T-Mobile.
Backstory: After purchasing the V35, I followed the instructions on cross flashing to get rid of the AT&T bloat here https://forum.xda-developers.com/lg-v35/development/bootloader-unlock-root-instruction-t4052145. The firmware I downloaded was from https://lg-firmwares.com/lg-lmv350ulm-firmwares/; however, the AIO and the USA versions are both the same. I flashed one of the firmware and all is fine, except now I get "Network locked" after I insert my SIM card from T-Mobile. I went AT&T's site https://www.att.com/deviceunlock/#/https://www.att.com/deviceunlock/#/ for an unlock code; however, I do not get a prompt on my phone to enter the code. This is after I flashed the phone.
My questions are, which version of the firmware was I to use so my phone is network unlocked AIO or USA? If they are both the same, how do I get the phone to be network unlocked so I can activate the V35 to T-Mobile.
TIA

You need to be on AT&T firmware to use the carrier unlock code. If you cross flash to different firmware before carrier unlocking you are out of luck. EDIT: see posts below where new information has emerged.
Obviously your V35 was not carrier unlocked/SIM card unlocked, in spite of what the seller said?
Unlike with the LG V30 series, flashing carrier unlocked firmware does NOT carrier unlock AT&T LG V35. You need to use carrier unlock code prior to cross flashing different variant firmware.
Perhaps you can contact someone with Octoplus box and get back to AT&T firmware to use carrier unlock code. AT&T doesn't publicly release KDZ for their firmware, but some dealers with Medusa and Octoplus boxes still somehow have it.

My understanding is that if you flash the firmware for south america, when you boot it with your sim card, a pop up will appear asking for an unlock code. Haven't done it myself but it sounds like in your situation it wouldn't hurt to try...
Of course, if u don't get a pop up, try the code that supposedly brings up pop up to enter code.
follow this link for the MIA version that should work.
cheers, let us know if you try it the results.
Thread Cleaned and it will end here regarding this back and forth, take care.
Hi OP, use LGUP to flash Mexican region kdz, insert your T-Mobile sim and unlock window will pop-up upon reboot and you can use the unlock code to unlock your phone. Good luck.

Is this guaranteed to work? I really want to use this phone.

Guaranteed? Well, as stated by those mentioning it here, I don't think we've actually done it, only repeating that others say it will work. So again, guaranteed? I couldn't guarantee it, but it seems unlikely that people would say it does work, and be lying about it?
Here's a GDrive link to the kdz you'd want to flash to try it. It's the latest Oreo for the south american region. Aside from using LGUP to flash it, you'd need an unlock code.
The md5 sum from this LG Page should match, to verify legitimacy.
Let us know if it works.

So I just flashed my phone from the link you provided and no dice. I reflashed, factory reset, insert the SIM card after completing set up, insert SIM card after factory reset the second time, etc. with no luck. I am not getting a pop to ask for the unlock code.
EDIT to add: So I found a set of instructions when I don't get a pop up asking for the network unlock code (below)
Second option (device doesn't ask for an unlock code with an unaccepted SIM)
1. Start the device with an accepted simcard (example LG V35 ThinQ was bought in Orange you need to insert an Orange card)
2. Go to the dial screen and press “2945#*model number#” (the same way you enter a phone number)
Example: the device is a P999 you need to enter “2945#*999#” or for KU990 you need to enter “2945#*990#” etc…
So far I am getting closer. Now I get a message saying SIM not provisioned. I will continue to research and troubleshoot. If I continue to run into a another roadblock, I will post here. Thank you all.
Okay, now I fracked up something else. I went from V350EM10h_OPEN_SCA_OP_118.kdz to V350ULM20f_00_NAO_US_
Okay now I am stuck at the LG Life's Good splash screen. I went back to LGUP and did not see it was defaulted to Refurbish going from V350EM10h_00_OPEN_SCA_OP_0118.kdz to V350ULM20f_00_NAO_US_OP_0218.kdz. I went back and reran LGUP with Upgrade chosen; however, the phone is still stuck at the splash screen. Help!
EDITED

So you've tired to reflash ulm and have an issue there. But did you get it sim unlocked?
here's also some instructions I found re unlocking sim if you don't get a pop-up
UNLOCK LG UNLOCK INSTRUCTIONS
ONCE YOU HAVE RECEIVED THE UNLOCK CODE EMAIL, PLEASE FOLLOW THE FOLLOWING INSTRUCTIONS CAREFULLY.
1) Insert a SIM card that is not from the original carrier in your phone and power on the phone.
2) Once finished loading your phone will ask you for the "SIM Network Unlock PIN".
If your phone does not prompt for a code, please dial 2945#* [model number] # to bring up the prompt
For example LG G4 D851: Dial 2945#*851#
3) Enter the LG Network Unlock Code.
If your phone asks for the "SIM network unlock PIN", use the NCK code.
If your phone asks for the "SIM Service Provider unlock PIN", use the SPCK code.
---------------------
But now you have an additional issue, you say you used 'refurbish' mode for both flashings? To the S.A. one and then back to the ulm one?
To my understanding, that should have worked. But whatever the case may have been, you're stuck now, from what I understand. If that's the case, all I can suggest is trying 'DL' mode for the ULM and select all partitions, OR maybe try 'Upgrade' (if you did refurbish" or refurbish if you did the other.
Sorry to hear you're having trouble, I guess, if you followed the procedure and it didn't work, then this is an indication there IS NOT a way to unlock the sim if you failed to do it on ATT OS.
Let us know if you're able to make any progress / got it sim unlocked or not. We'll have to start relaying the results so others don't have the same issue.

Actually, I was able to get the phone to be network unlocked. I mistakenly went from S.A. version to NAO as Refurbished instead of Upgrade on the LGUP.

Well that's not good. I can only suggest try doing a partition D/L? I don't know if that would help or not, but not sure it could be worse than it is now? Certainly don't try the other options like chip erase etc. Those are not for a situation like this, they will certainly make things worse!

Sorry to tell you this but you can't network unlock after flashing. You should have researched that if you're modifying the phone

You did not ready the whole thread. I was able to network unlock my device after using a South American firmware. In my haste, I used LGUP and flashed the NAO firmware as a Refurbish instead as Upgrade.
