[Q] how to reverse sim permanently lock LG optimus LTE p930

I have purchased an LG Optimus LTE P930 phone from someone on Kijiji and the phone is locked to bell but when I go to throw a different sim card in to unlock it I get "this phone is permanently locked and can not be unlocked". is there anyways to fix this issue?

Yeah, you need to find someone who can get your NCK unlock code. I got mine from a guy on eBay for like $3. Then dial 2945#*930# and enter the unlock code you are given. Easy peasy.
You might try these guys.

it does not give me an option at type in a NCK code as soon as it turns on with wrong sim it just pop's up with that same error

I don't understand, can you not dismiss the error and continue using the phone and then type in that number I gave you? If all else fails, maybe you can remove your SIM card and dial the number that way? As I recall, I had 0 issues unlocking my phone and I didn't even have a SIM card in it when I did it if I remember correctly...

A "freeze" usually happens after too many NCK attempt, usually 10.
what you would be looking for is an "unfreeze" code.
But if your Bell SIM still works it sounds like it is a service provider lock -SPCK- which is similar to network locked.
There may be a dialer code to reset attempt count, may also be able to binary edit it.
I reocmmend trying a site like this http://www.unlockallcellular.com/lg-nitro-hd-unlock-code-p-198068.html
there may be afew other, even on ebay. I would get with one that provides a guarantee. Usually invloves taking a video of you entering code to prove if it works or not. If not they will refund your money.
be patient as it could take a day or two.
I once paid $70 to unlock my dell streak 7.
Cheers.

did you manage to fix this? I'm having the same issue

Any solution i got this same issue on my G2 D802

My at&t pantech p6020 phone is saying that sim is locked and when I try to unlock it it says the incorrect unlock code was entered ten times this phone is permanently locked and can not be unlocked. What should I do? help me please

Suggestions on unlocking AT&T Note 4

I purchased an AT&T Samsung Note 4 but realized only later that it is locked. I tried the att.com/deviceunlock feature but it seems that the phone was still under contract so cannot be unlocked by carrier.
I then paid $20 to two different website to try and get a code for unlocking but both were unable to unlock and refunded my money. I am wondering now if I can unlock this phone somehow for me to give to someone for use in India. Any suggestions welcome. Do I try to first root it and then somehow unlock it?
Or are there no options and I just give to my kids to play over WiFi? Best regards and thanks in advance.

step1: pay off your phone if it's still under contract. keep your confirmation.
step2: go to https://www.att.com/deviceunlock/request/#/unlockstep1 and put in all the information
step3: once you get the code from AT&T, turn off your phone. take out your old sim. Put in another sim card like from t-mobile (micro sim)
step4: turn on your phone. It will search for network and ask you to supply the code. enter the code (be careful, you only have 5 attempts so don't make a mistake). Your phone should be unlocked.

Thanks but it is not my phone. I bought it off craigslist and now AT&T will not tell me how much contract money is left since it is not under my name. Hence, I can't go the official route. I will need to figure out how to unlock it if at all possible

You'd better call them and explain your situation. They should be able to help you out. If you IMEI is still clean then I think there will be a solution.

I got my unlocking done through www.unlockscope.com had same problem too.

Unlockguy.ca unlocked mine for $9 US. It was still under contract. I downgraded from 6.01 to 5.11 to get that price. It costs $29 if you're still on 6.01.

i got a unlock code from ebay for $2 took about 12 hours for them to give me it

Unlocking Moto Z 2 Force - Tmobile

Hi Everyone,
I've seen some posts about unlocking this but I'm curious as to whether I can unlock a T-Mobile branded phone purchased outright that has never been activated.
What have you all found to be the easiest way to unlock it? I've already reached out to TM via FB to no avail.
Let me know what you guys think.
Thanks!

Bootloader unlock is done via Motorola. To unlock your device for all carriers you must actively use the phone for 7 days. If you can't unlock it yourself after 7 days using the builtin app, then go in to a store. They can call in and help get it unlocked, but only after you've used the phone for 7 days.

Ok, that is my question.
The phone is brand new - no sim. I'm trying to get it to a prepaid wireless service and need it unlocked to do so. What you're saying is that I would need to activate it for 7 days for the bootloader to work, correct?
Tmobile themselves offer unlocking but only after 40 days of service which is a no go in my current situation.
Thanks again for any help. No other programs or apps out there that can unlock it more quickly without the amount of work?
You guys are awesome!

No. You are matching the two things together. Let me be a little bit simpler about this. All use different paragraph so you don't get confused.
BOOTLOADER unlock can be done about 1 minute after you buy the phone. You contact Motorola directly. Search this forum and you'll get tons of information on it
CARRIER Unlocking a T-Mobile phone to be able to use with any carrier can be done after 7 Days of use on a T-Mobile plan. If they recently bumped it up to 40 and that's what customer service told you, then go with that. I've been with them for a few years now and only needed 7 days, but then I was in the store working with one of the sales people and they called in about it. I may have gotten special consideration given the amount of time my wife has had an account with T-Mobile, but I did a carrier unlock after only 7 days.

I picked up a New tmo z2 force and started it with prepaid. The prepaid balance has to be at least 100$ and active for 14 days before they will unlock it.

Is that T-Mobile specific prepaid?
Sent from my Moto Z (2) using Tapatalk

Yes. Tmo prepaid
Also that's what the tmo rep told me. I still have like 10 days to wait...so I'll report back when it's done
Decided to call and try my luck with another rep. They escalated the unlock for me and did it with the hour.
Unlock app says permanently unlocked now!

You don't need to have it 7 days or whatever. Buy the phone full price, insert the tmobile sim, boot up and carrier unlock right away with the unlock app. Bootloader unlock is with motorola. That's it.

First, you need to activate your phone with a T-Mobile SIM card (you don't need to possess the SIM card, you can even borrow one for a few minutes) and a non-T-Mobile SIM to check if the phone is network locked.
You can check by following these steps:
1. Insert the “non-accepted SIM card” on the phone (Please check if your new SIM Card is activated, if not contact your Mobile Operator in order to activate it).
2. Wait for the phone to load
3. Insert the SIM’s PIN code (4 digits), if asked.
4. Read the message your phone displays, if you need the unlock code or to unlock via the Device Unlock App.
Mod Edit
Based on the message you have, you can contact T-Mobile again and ask them to unlock. Or you can use a third party unlocking service.

This doesnt work.. It says unlock failed.. tried permanent and temporary. Tmobile says theres an unpaid balance but the phones imei is not lost or stolen. The way to request an unlock is the previous owner and the imei # has to make a request. ugh and theres some dude who says he can do it for a fee (clean the imei) im trying to use this on metro and cannot because of the whole tmobile unpaid balance bullcrap

Correct me if I'm wrong. No T-Mobile phone is eligible for unlock unless it's paid off in full and remained on the network for 45 days after. I've unlocked plenty of them after they were paid off and this was almost always the case.

I unlocked my bootloader right after getting my phone. It's not paid off, as I upgraded via JUMP.

Thinking the OP is talking about carrier unlock.

Check what your IMEI's status is in the T-Mobile network with their service here: https://www.t-mobile.com/verifyIMEI.aspx
Note that if the result doesn't with "Congratulations..." you might not be able to unlock your phone.

Ah, got it. It's tricky when "unlock" has multiple meanings, lol! In that case, no, you can't carrier unlock until your phone is paid off

I posted a similar question before I realised there was a thread already on this topic. Can anybody confirm that if you buy a tmo version from Motorola, then what are the conditions for having it unlocked? Is it $100 credit balance (for me that would add $100 to the cost) or immediately on insertion of a TMO SIM or some other conditions? Does anybody have any experiences they can report? Thanks

I can tell you I just tried getting a tmobile variant unlocked (375 outright, I have AT&T) and had a buddy with a tmobile account make the purchase and put his active sim in it and they would not unlock it. Stated it had to be on tmobile network for 40 days. He called multiple times and argued it's already paid off but they wouldn't budge. So I returned it. Had to eat a 50 fee for returning it. I chalk it to a lesson learned.

I was going to buy the phone from the Motorola website for $500 so $375 is a good deal. The problem is while I have a tmobile SIM card on a prepaid account I don't live in the US and while I'm travelling there soon I won't be on the network for 40 days. so I guess it won't be unlockable while I'm there and certainly not once I'm gone.
I wonder what the unlocking Services online are like? Has anybody had any experiences to relate

There is also a temp unlock through the unlock app. Still fully sim unlocked but for only a short time. Then if you do come back to the US for 40+ days you can try for the permanent unlock.

OK _ just got off both a phone call and chat session with TMO support. Basically the phone has to be on their network for 2 billing cycles and then you can call them to unlock it. That applies even apparently to the $3/month plan. I do have somebody who could do that but they would have to send the phone to me and I am not sure you can do that with its LiOn battery inside.

How am I unlock my pixel 3a XL to all carrier

I have a locked mobile (T-mobile) , how am I unlock my pixel 3a XL to all carrier
I would love to receive step by step answers whenever possible Help!
Thanks in advance,

You must get T-Mobile to carrier unlock the phone. They are the only ones that can do it. However, if you still owe money on the phone, you will have a hard time getting them to agree to unlock it. Honestly the most successful method I have seen is to reach out to the main T-Mobile account via a direct message on Twitter. Explain that you need to get a carrier unlock and see what they say.

thanks a lot for the answer
1. I don't have a T-MOBILE sim
2. Is there no way to replace / override the existing operating system
3. Is there no software capable of hacking the system

The first hurdle before you can do anything with the os is bootloader unlock. That it's not possible work a T-Mobile phone without T-Mobile doing it. Good luck.

I hate that a person's banner doesn't appear in the OP, so I didn't realize you were in Tel Aviv. Again, I think the best option is to reach out to T-Mobile on Twitter and explain that you acquired this phone, but you live in Tel Aviv and need them to sim-card unlock the phone so that you can use it on a local service. They may give you a hard time if there is still money owed on the phone (ie bought on an installment plan), but it the phone was bought outright, or if you pay off the balance on the phone, they definitely should sim-card unlock it.
Once it is sim-card unlocked, you can then bootloader unlock it which will give you the ability to install custom ROMs, kernels, etc.

Buy an unlock code from any service out there. Slam your new SIM card in and input your unlock code

Anyone know more ways to deal with the issue?

Can you recommend a reliable site that knows how to service and not just take the money

you can try to merge the backup from a fully unlocked phone using qpst program and upload it via edl mode to your phone

Dirty secret.... Call and tell them you're someone either famous or C level of a company and you're going to be landing in whatever country and you need your phone unlocked immediately to use a local sim for business purposes. If or when they question the account name it's just the account of your assistant to obscure your identity. Major Telecoms won't tell you about this but I can tell you 100% from experience this is how things work. Well I can't at least say with at&t, Verizon, TMobile and Sprint. As in I've seen the tools with my eyeballs.

Small note:
My ROOT and BOOTLOADER are locked

So I'm kind of in the same boat. I just purchased one that is sim locked to Verizon. I have seen things about leaving a Verizon sim in it for 24 hours and it will unlock, luckily my work phone is Verizon so I'm testing this theory.
But can anyone tell me if this is permanent? Will it survive factory resets and such?

Question AT&T bootloader & Carrier lock

Well since I have found zero threads about AT&T bootloader unlock. Does anyone have any solution? Whenever I put in any other sim, it just says that unable to use any other sim apart from AT&T. So I just factory resetted my phone and blocked the device setup app from accessing the internet via the Netguard app. That's allowed me to use any SIM card apart from AT&T however it's not a permanent solution but I'd like to know my options. Any chance of me working around a carrier unlock or possibly bootloader unlock? I bought this phone outside the US, and to my stupidity I never factored in that this was also a possibility that it's carrier locked, that too with a bad standing. I tried unlocking online but it just says that there's payments overdue and that I should log into my AT&T account. Tried calling their customer service, however they're useless and unhelpful. Learned the hard way, depressed that I've kinda wasted my money. Can there possibly be a way to carrier unlock my device and bootloader unlock?

Can you return the phone? The seller should have disclosed that information and the phone will technically only be used on AT&T until it's paid off, and currently on AT&T (for 60 or 90 days before they will sim unlock)

I tried going back to the shop, they just said that there's no way that they offer returns and that I should just contact AT&T for this issue. I'm running out of options and patience. I'm basically stuck with this phone. There's really no check and balance here when it comes to these matters
