Question about unlocking the g1

I just bought a g1 that is not unlocked, and I wondered if I have to have a tmobile sim card to unlock it.

No, the opposite, you need a sim card from another provider (along with the unlock code) to unlock it.

In The U.S., i saw you were not, you get the code from T-mobile unlike most other U.S. carriers they give it to you. Then any sim card other than an active T-mobile, even old non-active ones I have used as it just needs something to look against to enter the code. Here is the instructions....
T-Mobile Sim Unlock Request
Sim Unlock Reference: nnnnnnnn
IMEI: nnnnnnnnnnnnnnnn
Unlock Code: nnnnnnnnnnnnnn
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your HTC device.
1. Insert the foreign SIM card
2. Power on the device and the display should read "Please input unlock code"
3. Enter the unlock code and the device should display "Phone is unlocked."
4. Allow the phone to scan the network (or manually click on the antenna icon to do this)
It is very important that the instructions and SIM unlock code are entered correctly as listed. If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support.
Thank You,

[Q] Unlocking Optimus Black

I have Optimus Black from Japan that unfortunately locked to Docomo.
It's gift from my boss
Is there any way to unlock the sim
so I can use with local provider (Indonesia)
Thanks in advance.

Found this,
1
Get the IMEI number for your phone. This is also known as the International Mobile Equipment Identification Number. You can do this in one of two ways. Remove your battery, and look for the 15- to 17-digit number underneath it, or type in *#06# and wait for it to appear on your screen. Once you've gotten it, write it down on a piece of paper.
2
Find a website that sells unlock codes for LG phones, like TheTravelInsider.com. GSMLiberty.net and GlobalUnlock.com (see Resources). As of 2010 these sites charge between $9.99-$24.99 for their unlock codes (prices as of 2010).
3
Go to the site that you have chosen and enter the IMEI number. Find the make and enter LG, then enter the model of your phone, the country that your phone is registered in along with the mobile service provider, and click "Submit." This will bring you to the next page, where you must enter your payment details and a valid e-mail address.
4
Get the unlock codes from your e-mail.
5
Turn your phone off, removing the battery and the SIM card.
6
Get a SIM card from a different network. If you don't have one, borrow one from a friend or purchase a prepaid card from any convenience store.
7
Replace your battery and turn the phone back on. When it comes on, it will ask you for a code. Simply enter the one that you got in your e-mail exactly as you see it. Do not add any additional spaces or characters. Enter "OK" and wait a few seconds. The phone will beep and flash and turn off.
8
Wait a few more seconds and it will turn back on automatically. If it doesn't push the "On" button. When it comes back look at the top of the screen. If the unlock was successful the new network name will show. If it doesn't work the first time, try the unlock code again.

that would be my last option actually
I would like to do unlock by myself first
so I came to XDA to search some tutorials but no result
thanks anyway

(Note: In France, after 3 months, you have the right to get the unlock code free)
Just to know, that's not possible to unlock phone using Custom ROM, right ?
In this case, I suppose we have to go back to Stock ROM but what version !?
I had v11c first, I guess I had to flash this one. But will it work if I flash v20n ??

Of course different software/rom work, but different sim cards wont work. Simlock has nothing to do with roms ;-)

I'm in the same situation, trying to unlcok Optimus Black, and saw this on xda: http://forum.xda-developers.com/showthread.php?t=2137840
Haven't been able to make it work though. I'm having trouble with my PC communicating with the phone. adb, USB Mass storage all work. But the COM port option is not available in SmartFlash Tool.

Lg Optimous 2X P999 unable to Unlock

I have LG Optimus 2X locked to Wind. My son installed the gingerbread software on it around six months ago. The phone works great. I tried to unlock it but I am unable to type in the code because no window pops up after inserting the sim card from a different provider. the phone goes to home screen. I typed in the numbers from instructions provided by the person. The message reads NO ACTIVE NETWORK AVAILABLE when the sim is from different provider but if I type in the same numbers when my active sim card is inserted the USSD code start running and after few seconds the message is IME code concealed. Thus I can not get the little window to type in the unlock code. Thanks for help in advance.

What are you typing to get to the dialog for entering the code? For P990, it is 2945#*990# (I know it works, as I used it myself), so I would think for P999 it would be 2945#*999#.
Keep in mind that the phone may not be able to accept the unlock code for several reasons (not sure about your phone, though). For example, too many unsuccessful attempts to enter an unlock code could lock the phone permanently. Or, the operator-branded firmware would not allow access to this function. Places that provide unlock services usually advise you to check in advance, before purchasing, whether you can actually enter an unlock code into your phone...

I think you need to be on a stock ROM to unlock the phone. Once done, it will remain unlocked and you can restore your previous ROM from a nandroid backup and try the other SIM card. Mind you, the P999 only gonna work in 3G either with Mobilicity or Vidéotron. With the rest of the carriers (Rogers, Fido) you will only get 2G connectivity.
In regards to Wind/other stock ROMs, nandroid backup/restore, etc check the P999 (aka G2X) dedicated thread. The phone is falsely advertised by Wind, it is not the Optimus 2X. The right thread for further information:

I think that i've unloked mine with flashing different baseband.
It was locked on my network but after flashing several roms and basebands it works with every sim.
Is that possible?
And when i flash some bb my sim is locked too.

I'm having the same problem as the OP. I have a Wind phone, but no matter what I try I can't get the unlock prompt screen to come up. I've tried 2945#*999# AND 2945#*990# with no luck.
But, I do have a Paranoid Android ROM on it. Maybe I have to revert back to stock.
Does anyone know where I can get the stock Wind ROM?

Unlock code screen fails to appear on LG P999

In trying to unlock my LG P999 (out of contract) T-Mobile phone, I find that when I start the phone with an ATT SIM card (expired) or a StraightTalk SIM (active), I fail to get the screen that allows me to enter the unlock code. Any suggestions?

Sir,
Please wait until mods will move this thread to the device specific forum.

H811 LG G4 Network Unlock Help needed or different stock firmware

I have lg g4 from tmobile with a tmobile device unlock app. It does not ask for network unlock code either with a different carrier. Also it does not pop up the network unlock code window even if i type the 2945 code (ithink). IF i use device unlock app it says device unknown by provider please contact customer care. I ordered service remote unlock they where unable to unlock but they had to refund the money because they could not unlock.
Funny think is T-Mobile is saying its not a T-Mobile phone because they cannot find the IMEI number in their system.
The phone is an original T-Mobile phone, with original T-Mobile packaging, software and original labels with the imei.
The only way to unlock this phone is if i can flash stock firmware on the h811 without the tmobile crap.
am i screwed?

How long have you used that phone for as of now? T-mobile requires you to use the phone at least 40 days on their network and it needs to be paid in full if it's financed. I yours is still financed maybe the op that thread could help you http://forum.xda-developers.com/g4/general/t-mobile-free-sim-unlock-promotion-t3138438

Can you link us to the App that unlocked it?

please read my post again. tmobile sim is working fine on it. It does not reach even the permanent or temporary unlock option.
T-Mobile customer service does not even recognize the imei number at all. They say its not tmobile phone and clearly is.

1) Does the IMEI in settings match the IMEI on the box/back label?
2) Are you sure this is a T-Mobile US phone and not a T-Mobile european phone?
3) Where did you buy it? (direct from TMO, eBay, CL?)

please read his post again. you must use the phone with your t-mobile SIM card in it for at least a week until its IMEI (dial *#06# to display it) shows up in the "Check Unlock Status" pop-up in the Phone section of the My T-Mobile website. If it doesn't show your IMEI there, the phone is not associated with your account and the unlock app will not work.
