Hi All -
I've searched everywhere for the answer to this and haven't been able to find it, so I figured I'd post here. This is the scenario:
1) I have a Moto X that is locked to AT&T
2) I wanted to give the phone to a friend who is on Sprint, so I paid for an unlock code
3) Even after unlocking and inserting the Sprint SIM, I still received the "SIM Network Unlock PIN" message
4) I now want to basically restore the phone completely back to the way it was (locked to AT&T), so it can be used with an AT&T SIM
5) I flashed the phone using RSDLite and the correct ATT ROM, but after the flash finished successfully and I insert a valid AT&T SIM, I still receive the same unlock message.
So my question is basically, can I get the phone completely back to being locked to AT&T, essentially the way it was out of the box? I'm also willing to flash it with Cyanogen or another ROM if that would help.
Any help is greatly appreciated, thanks for your time.
I have same issue, I had my Sim working for a couple of days but I wanted to return to stock to receive further updates and I flashed it with correct at&t firmware package but now there is a popup every time when I insert Sim about unlock code and I am stuck ... I think that's because of erasing modem st1 and modem st2 during flashing with RSDlite ... Is there anybody to suggest something helpful

My xt862 was on the xt883 ROM when I bought it off craigslist. I had to flash it back to stock to get rid of the other guy's Google account (it wouldn't delete, said it needed factory reset). After wiping, and flashing back to stock, I had to re-flash the radio.img from that Chinese ROM (and swap out my build.prop) to get it working on GSM again. Have you done these two things since flashing back to stock? I don't know what the other guy did in the process of putting my D3 on the Chinese ROM, but the GSM capabilities were lost when I wiped it (it wasn't back to stock yet, it was still a Chinese ROM, but likely locked to Chinese bands...really weird). I had to put it to stock before I could get GSM back.
So, if you haven't re-flashed the radio.img and made sure you have the tweaked build.prop in /system, then you might want to do that and see if it starts to work.
If you already did these things, try replacing your SIM and restarting several times. Mine decides to lose signal or forget which operator I'm using occasionally, so it isn't quite 100% reliable. Not entirely sure why.
Good luck
EDIT:
Also, you shouldn't need to unlock the phone ever again, as in, calling Verizon to get an unlock code. You only have to do that once, and flashing back and forth to different ROMs, even wiping the phone, doesn't get rid of the unlock. Just fyi.
Hi all;
got my sim unlock code for the nexus 6. when i put in a non carrier sim and boot back up no menu comes up for me to enter the unlock code, just says no service, if i put the original carrier sim back in it works fine..any way to manually invoke the unlock code menu so i can enter it or any other tips..thanks in advance
I can't help with this but it may help others to say what carrier you're locked to..
Sorry..iT's locked to rogers in canada
Since the phone was already used on Rogers, perform a factory wipe to use a new carrier's SIM
My Rogers Nexus 6 came unlocked out of the box. I expect yours is as well. I have never heard of a locked Nexus device sold by a Canadian carrier.
Weird
..just says selected network (telus) what im trying to connect it to is unavailable. Factory reset at this point too
Hi, im experiencing some weird resets when i recieve calls, i reset the note 5 like 3 times and still the same, so i downloaded the NZ rom from Sam Mobile and i was wondering if this phone i bought is sim locked and i flash the new rom i will lose my unlock??
Is there any way to know if my phone is factory unlocked or if its locked whit what company?
Ok I find the question a bit strange but will answer to the best of what I understand. If you want to find out if your phone is unlocked just pop in another sim from any other provider and see if you get service or even if it even attempts to find it. If you get invalid sim msg or something similar you are locked. Also to answer your question to which carrier is it locked, that's obvious as it would be the carrier you are currently using. As far as flashing a rom from a different model note 5, I won't recommend without extensive research as you could brick your phone.

Sorry for my bad English, the phone is already unlocked but idk if was manually unlocked or factory unlocked because im from Bolivia and the Note 5 Says spark(NZ Carrier) and accepts any carrier, the problem is my fear of losing the unlock after the flash is this phone was manually unlocked
Hi everyone,
I've been using an SM-920T 64GB Galaxy S6 bought from T-Mobile last summer. I did a permanent unlock using the T-Mobile application and since July I've been using the phone on the AT&T network. I just rebooted my phone today like I always do and upon restarting I got an "Invalid SIM Card" and it brings up a SIM network unlock PIN window that I can dismiss or enter a code into. What is going on?
I'm running XtreStoLite Deo 2.4 if that makes any difference.
Also, does anyone have the T-Mobile Device Unlock apk that comes stock with the phone? This is how I unlocked the phone in the first place but I don't have that app anymore since I run a custom rom, and the play store won't let me download it because I don't have a t-mobile SIM card in the phone.
Thanks!
Well for the benefit of whoever has the same issue. I flashed back the stock ROM via ODIN, ran the T-Mobile Device Unlock app, it said Unlock Unsuccessful in big, but right below it said the phone has been unlocked permanently. I put in my AT&T SIM and it was working again. Then I flashed back my TWRP backup and the phone remained unlocked. The non-Tmo ROMs get the unlock popup when a foreign SIM card is inserted, so getting an unlock code should work, but I didn't want to wait 3 days to receive one.

Can you tell me what ROM you used? I have the g920T also, and bought it USED unlocked from ebay, but it had the FRP (factory reset protection) lock on it. I had my US cellular SIM card in it, even though I was stuck at the "enter your previous used google account on this device" and the SIM seemed to work (saw the LTE bars above).
But the only way for me to bypass the FRP was to flash to the ROM to stock (which I used the G920T tmobile ROM) and I got to the home screen but now it says "Invalid SIM card. Network locked SIM card inserted" just how you were saying.
When I try using the Tmobile unlock app, it says "Server not responding. Please try again later." .
Please help!
I received an unlock code from AT&T to unlock my phone for use with other carriers so that I can use it when I travel outside the country. But it's not working for some reason. Here is what happens:
Turn phone off
Take out AT&T SIM card and replace with friend's T-Mobile SIM card
Boot phone completely
Phone automatically prompts me for unlock code which I enter
Phone goes to home screen
Phone prompts me again for unlock code
I tried 3 times and stopped trying because after 5 attempts the phone supposedly permanently locks to the AT&T network.
I AM rooted running CM13. Is that the issue? If so, what do I need to do to get the unlock to work? I tried searching but I'm only seeing results related to unlocking bootloader, etc, not surprisingly haha. Thanks!
Your system must be totally stock to SIM unlock the Nexus. Flash a stock image.

Okay to keep bootloader unlocked and keep root? Just need the stock ROM?
And then once I flash stock image and unlock SIM, okay to reflash CM13? And the SIM will remain unlocked?
Thanks again!
I wouldn't bother with root on the stock image since you'll be reinstalling your custom ROM afterward, but you can keep your bootloader unlocked without worry. Once SIM unlocked, the Nexus stays unlocked.
