You will need to call T-Mobile and get the code unfortunately. Sorry that we can't help in this issue!

Unlocking GSM / SIM for us carriers

In reference to THIS thread about unlocking the GSM to enable the use of a sim card from a US carrier, I was wondering if the phone works exactly the same once I actually switch it to GSM (mainly data) and does it depend on which carrier I switch to. I wonder which one would work best with this phone.
Well anyway I tried reading into the steps to make sure I understood before I even begin to tamper with it but im still unsure and nowhere near tech savvy and im sure I will find a way to screw it up. I was wondering if anyone can :fingers-crossed: OH SO KINDLY!! walk me through these steps or at least the parts I have major trouble with.. I would appreciate it.
I HOPE IM NOT ASKING FOR TOO MUCH.!! Any help at all would be appreciated. Thanks in advance.

there are many threads on how to do this.. more than one and its not that hard... root,, unlock, and then flash japanese radio. If you have new 2.3.5 firmware you are out of luck until someone figures out how to unlock the bootloader. Bootloader MUST be unlocked before you can flash japanese radio.
How do I know which firmware I have?
What about data, will it work with an unlimited everything plan?

Settings, about phone, android version.
And yes, everything should work just fine. Only thing is I heard there is something wrong with using it on t mobile. Something about 3g I think.

[Q] Phone permanently locked

I bought an E970 on Ebay and when I tried to unlock the phone it did not accept the code. I used the code 2945 # * 970 # to enter in the SIM Unlock Process, and on the Network Lock option it says "this phone is permanently locked and can not be unlocked". Is there any way to reset this setting? Can I use a box to remove this setting, or reset the counters? Thank you
I contacted LG and they told me that only AT&T can restore the phone. Is that true?
Does anyone know how to resolve this?
Sounds like a SIM lock, meaning an unlock code was typed in like 6 times wrongly.... I am pretty sure it is just locked at that point. OR it is stolen..

I don't know much about this but I don't think that's true. SIM unlocking the phone doesn't happen over the networks so AT&T, other than having the correct code, doesn't have much to do with it. Also, nothing is permanent on the phone other than /system which requires root to change. I think you could solve your issue by factory resetting the phone. That should clear out what ever file or app is saying you are permanently blocked after incorrectly entering a code.
You could also try clearing data for certain apps that have to do with the SIM card and phone app. But I have no idea which ones and it could cause problems.
EDIT: I saw whoamanwtf's post. I have had my phone sim locked before and yes contacting the original carrier will get you the code. I thought you were talking about sim/network unlocking.

I am talking about SIM/network unlocking.
I bought the E970 while in the US, but I live overseas in Europe. I used the phone in the US with a AT&T Sim card, when I returned to my country in Europe I tried to unblock the phone so I could use it with Vodafone, but the code didn't work. The phone is already rooted and have the bootloader unblock all by me.
That's when I used the code 2945 # * 970 # to enter in the SIM Unlock Process, and on the Network Lock option it says "this phone is permanently locked and can not be unlocked".
The previous owner must have tried to unblock the phone using Internet codes, you can only insert 10 wrong codes, before the cellphone locks itself for good, meaning it stays blocked to AT&T. My question is does anyone know how to remove the setting of permanent locking? The phone works fine, but I cant change the SIM card to my carrier, it won't accept the SIM.
I was told that those kind of setting are in a different part of the phone, in dedicated chips and you need to use special tools like the SE tool box, or the Z3X box. But none of those boxes currently support this phone.
Does anyone know more about this? I really need to use the phone and I can't because my Vodafone SIM card is not accepted.
Would installing a custom ROM reset everything so you could try unlocking again?

This is just guessing, but no, I don't believe so.
This isn't a ROM issue.
The only thing that I can think of that MIGHT work is lgnpst... or maybe even the n4 conversion and then back to the stock OG.
The only reason I think that may work is it completely overwrites some partitions that are otherwise untouched by recovery/flashing/etc.
Mind you, the process is really dangerous and not supported by most of the devs (including those who pioneered it).
OP - either try and sell it for ~$100 and get another one... or try those methods since it doesn't do you much good atm.
Or go to the irc channel and see if the much much (much much much) more knowledgeable people in there know a fix.

I'm using the Base 0.7.3 with Nocturnal LE MOD
But the phone was already like this even with stock rom.

Where can I find the lgnpst?
Usually this kinda of problems can be solved using dedicated hardware/software, such as service and repair tools.
I'm sure LG have them, since they're the ones who made the phone, so it's a matter of time until someone makes a commercial repair tool.
I just need to know if someone as ever tried to read/write or at least located the EEPROM with the hard network lock.

You'll have to use the links here to get them from IRC, it is not allowed to be posted on XDA.
(I would ask somebody in there if it is even possible).
LINK.
But again, Idk if that will do the trick or not, it is the best chance though.
Does anyone ever tried to find were the phone saves the information about the sim card? Or about the carrier?
Maybe it's possible to fool the system.
Does anyone know where the information is written?
Does the phone uses a separate chip or is it in the internal memory?
Sorry about all the questions, I just want to understand why the sim lock can't be removed.
If AT&T can remove the lock, it's just a manner of finding were that information is.
The phone searches for the sim card only after booting, right?

LGNPST it and see if it fixes it. or like Bleached said, do the LGOG conversion then fastboot erase everything.

I believe I read that there are some partitions the conversion leaves intact.
So since you have to go the irc anyways to get lgnpst, I would ask them there if that would even fix your issue. If it won't they can save you from performing a few hours work and risky hacks.

I flashed the original AT&T ROM using lgnpst and it's the same.
From the experience I have from old phones (especially Nokias) the permanent lock is written on a special chip.
Normally you need to use special software/hardware like the Z3X-Box or SE Tool Box.
They can repair almost everything on a phone, but right now they don't support the LGOG. I think it's because they're from Europe and E970 is America only.
Anyway I'm going to send the phone to America, maybe the guys at AT&T can repair the phone. But I have my doubts since I purchased the phone on Ebay and don't have any type of receipt. And if you permanently block your phone that's normally your fault, so they refuse to repair.
One thing you could try add a last ditch is to pull the battery by opening the case. Then factory reset and start over by root freegee.

[Q] Cell Radio Cuts Out Completely

Hello!
I have a T-mobile Optimus L9 P769BK. I was on software revision G and I rooted it. Regardless, the problem started before I rooted it. My cell signal cuts out completely, the only way I can get it to come back is by rebooting the phone. Does anyone know where (and if) the android OS stores error logs? Also, is anyone else experiencing it?
I hope it's the SIM card and not the phone... We'll see.
Regards,
-Curly

That's not my problem. Intermittently, I get no bars, and an 'x' in the corner.
Still struggling
Logcat is great, but nothing is coming up as to why my cell reception cuts out.
It sounds like a bad sim. T-Mobile stores will give you a free one if you tell then that Tech Support told you to get one from the nearest store. Which is exactly what Tech Support will tell you. This way you save time not making the un-necessary call.

Something similar, had it in airplane mode, switched it off while at the gate and made 2 calls successfully. Notice in customs that I don't have a signal and figure maybe because they have jammers there for some reason. Get to airport doors and still no signal, had to call my hotel shuttle on my other phone. I rebooted the phone while on the shuttle and got proper signal again.

It's not the SIM card. I got a replacement from T-Mobile, still having the problem. Tried the replacement in an old phone and I don't see the problem.
I just got the phone back from LG. Let said it was a "Language Error" and they "Installed new software". I'm still seeing the problem.

This sucks that you are still having the same issue after 4 months. Try flashing one of the Jelly Bean KDZ files for the P769:

If that does not work I am not sure what else to try. It could be a network issue or the phone still has a hardware problem which would require LG to fix.

[Q] Carrier Unlock Question

Alright so I have a Verizon Galaxy S4 and am currently running CM11 on it, and this summer I am going on a school trip to London. I am already looking into getting the 3 (carrier) unlimited data, 300 minutes, 2000 text plan for my phone (I'll just use Google Voice for calling mostly), but I was wondering if Cyanogenmod unlocks the carrier sim itself or if I need to.. And if I need to will I need to install an app or will I have to go to a Verizon store? If I do have to go to a Verizon store, will they question me about me rooting my phone and not help because it's rooted, or will they do it with no problems?

the phone is already gsm unlocked for international use, you might just have to manually input the apn's, but whatever carrier you use there will tell you what to change when you pop in the new sim

Okay, Thanks for the response! I really appreciate it! I know you said the carrier will help me with the apn but could you send me an article or video on how to do that so that I will have an idea on what to expect?

No problem, I'm sure you can search youtube for a video just as good as I can for further explanation, but this is how you get to it:
go to settings app
go to connections tab
tap mobile networks
tap mobile networks again
tap Access Point Names
(never did this part myself before so I'm not positive) when you put the new sim in it will let you hit the "+" button at the bottom of the screen, and that's where you put in the info that the carrier will give you

Alright Thanks for all the help! But sorry to keep bothering you, I've never tried changing sims before so I'm not well educated in this part of rooting, but I went to that section of the settings menu and The access point names option is grayed out. Do you think that is a Cyanogenmod thing or a what? I;m guessing it's CM.

oh right you're on CM, I *think* it will only let you go in there if you put a new sim in, but I'm not positive. Never had to change my sim just know the process. If someone else doesn't chime in on this thread by tomorrow, then I'll PM some helpful people to see if they have more knowledge and will get back to you.

On the stock ROM it's greyed out as well as long as a VZ SIM is installed.
