I did purchase an unlock code from unlock-code-central.com. Put a different SIM, typed in the code, got the message all went well, however phone says "emergency calls only"
Can anybody please help me with this?
Is my phone unlocked or not?

There was no need to purchase the code as there are several threads here on how to menu unlock it. But since we are beyond that, I'm guessing the other SIM is not provisioned and has no service on it. Try using a friends T-mobile SIM. That's how I was able to check the menu unlock method.

Thank you for your answer.
I used a regular size Vodafone SIM which I just used in Europe last month, on my other phone, so that SIM should be ok.
However I used a SIM cutter to transform in into a microSIM . Visually looks ok too. Could it be that in this process the SIM (now microSIM) got damaged somehow?
When I first insert it, I was prompted for the unlock code, which I typed, got an ok message, but that's about it.
Now says "emergency calls only" and it does NOT prompt me for the unlock code anymore.
Original ATT SIM works just fine.
There's more: I just put that Vodafone microSIM into my wife's phone (which is unlocked) and it works fine.
So bottom line, I used an unlock code which apparently worked (got the message "network unlock successful") but the phone does not appear to be unlocked.
I will definitely try a T-mobile SIM as soon as I find one, but in the meantime which is that "secret code" to check network status for this phone?
*#7465625# does not work and returns "connection problem or invalid MMI code"
Thank you
anybody has the answer to my question ?

Ok so here's my problem.
I have an I9505 previously with a GE custom ROM and modem version XXUEML2, everything was working fine so far, the only "strange" thing was whenever I reboot the device the Cell Network will take about 3 minutes to reconnect, and I constantly lost the 4g connection which I attributed to problems within my carrier.
So a couple days ago I re-installed my custom ROM (was having problems with the Kernel) and after it boot back I wait to my Cell Network to connect, which never happen. So I went ahead, format everything, re-install the custom ROM and no luck.
I tried everything, updating the Baseband to XXUEML6. Install the Stock ROM (which was locked, but the store where I get it unlocked it by warranty), install another Stock ROM (right now I have the I9505XXUFNC4_I9505PHNFNC1_PHN ROM) and I still cannot get signal).
Did my modem just died, or the "warranty" guys unlock my device in a wrong method. I don't think is a problem with my IMEI 'cause I still have the same as the dive box says.
Hope someone can guide me before I take it back. Thanks.

Well, when I bought the device, it was intended to be unlocked, but for a strange reason my device (only mine 'cause we bought 2 the same day) came carrier locked (MEO from Portugal) So I sent it back to warranty. After a week I get my device back "unlocked" (Same ROM, IMEI) but I notice that it was rooted, which only makes me think that they take it to a third party which unlocked the cellphone with a method that required root. I didn't care, I had signal and 3G,

There use to be possible using this guide, with the old firmwares as far as i know is not possible anymore unless you still have that firmware
http://forum.xda-developers.com/showthread.php?t=2282683
The other way is by an unlocking code ( you can buy in many places) once is unlock , stays unlock..no matter what you flash
Try something go Settings/connections / More networks/Mobile networks/ network Operator/ choose your carrier and see if it let you register, try others and see what kind of message you get

Already tried to choose my carrier, but sometimes it doesn't even appear, and when it does, connecting to it just throws and error saying "Not Registered On Network".
What I fear is that somehow they unlocked it using the Ariza patch (or other unlock method) which should not be used.
Also after digging some info, that kind of error happens when the device have been IMEI locked, which could be also a possibility given that my SIM works on any other device, but not otherwise. I will have to give a call to support service to discard this theory.

Hi ,
I also feel the same that is the problem , it has not been unlock right.
check with them , let me know what they tell you.
Ok, I have more information, typing on the dial *#0011# to get the Service Mode Menu, it says at the bottom IMEI CERTI: NA. But if y dial *#06# I get my correct IMEI, is something wrong with the EFS folder?

Hi ,

For sure something happen when unblocking the phone
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?
Hi,
I recently bought this Sprint G6 from my friend as he said it's already unlocked and can use any sim.
It work fine except when i reboot the device, it run "Confirguring device" then stuck at step 1 for a while then just close and said "please contact your carrier to config the device".
It's kinda annoying, is there anyway to get rid of that? Also, can i flash TMobile rom to my Sprint G6?
If you enter ##brand# on the dialer it removes the sprint branding which might get rid of that issue too as long as the sim card is removed when you enter that code. Note it does reboot the device but none of the user settings are reset or removed just the carrier specific stuff.

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.

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!

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!

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.
