Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio
If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.
Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.
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.

So you're all set now? sim unlocked and back on ULM? If that's so, that's good news.

Only the phone is network unlocked. It's still stuck at the LG logo screen and does not boot up.

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.

Awesome, good job.
Hello,
I have an old galaxy S5 I am trying to network unlock so I could get rid of it. I called Sprint to get it unlocked, and after a long time being placed on hold, I was told the phone is not unlockable. However, they provided me the unlock code. I tried putting on a different carrier sim expecting to be prompted to enter the code, but that didn't happen. I only got an invalid sim error.
What can I do?
EDIT: it is possible to unlock, see below.
It is not unlockable with some "unlock code", you have to hack the modem firmware partition and flash it to the phone.
There was an online unlock service for $35 at http : / / idoneapps . com and I've successfully unlocked 2 phones with their service but the website does not work anymore, also they do not reply to email or facebook.
If anyone knows the similar service - please share the link, I'm interested too.
I've managed to unlock the G860P for international SIM cards, check this thread: https://forum.xda-developers.com/t/confirmed-sim-unlocked-s5-sport-g860p.3128965/
Can't seem to find this answer. If I bypass the SIM unlock part, unlock my bootloader and load a custom ROM, like LOS or crDroid, will the new ROM overwrite the SIM lock? Could I then use an international SIM (I live in the US) when I travel abroad?
T-Mo is giving me the run around cause I'm not a T-Mo customer, saying they won't SIM unlock for me.
Here's how I did it: Settings -> About Phone -> scroll down to Network Unlock -> hit Continue (mine's unlocked already so I only see "Continue" or "Cancel" for a brief moment before it says, "This mobile device is permanently unlocked and can be used with any carrier!" Also I was not a T-Mobile customer when I unlocked this phone (never have been) and did this over Wifi in another country. I didn't have to contact T-Mobile either. I recommend trying to unlock it from the menu because it seems a lot easier than attempting a bypass.
Is the phone giving you some kind of message/error when you attempt to unlock using this method? Or are you attempting an experiment with the phone for research/discovering additional SIM unlock methods?
Hi
Is there a way i can run two sim at the same time in oneplus 7t pro mclaren hd1925?
Note that there is a dual SIM slot in my mobile, but only one of them works
Thanks
