TMobile MDA Unlock, is it permanent?

I recently ordered an unlock code from TMobile UK and have successfully unlocked my phone. The question is whether it remains unlocked forever or will it lock again when I update to a new ROM (official or cooked).
Thanks in advance

or by hard restart
does it remain unlocked after a hard reset?

as far as I know when you ordered a unlock code from T-Mobile then it is a sim unlock number to allow you to use other providers in the phone the CID lock is is still there .Still after a hard reset your unlock from T-moblie you should still be able to use other sim cards from other providers

So basically keep my code safe???
Is that what you are saying? That I will need to unlock again when I update with a new ROM?
If so, I'd better keep a note of the Unlock code!
Thanks to everyone who responded.

Htc one netlock

Hello,
i bought a htc one yesterday,but it has t mobile branding.
i already did s-off on it and flashed a ruu without branding,but still ive to enter a network code to unlock it.
if i go to to the bootloader,there is option with the name "SIMLOCK",if i click on it i get the message sd-init fail.
please how can i get rid of the branding?

It sounds like you haven't unlocked your phone for a non-T-Mobile SIM card. You have to get a code for that. There are sources online that can provide it for a few dollars.

where can i get them?

AT&T HTC One on Vodaphone in NZ

I'm from the US and am in New Zealand for a month. I own an HTC One which I purchased from AT&T and have been using on their network in the States. I've unlocked the phone, and also have S-Off. I've purchased a prepaid SIM card from Vodaphone in New Zealand. When I insert the SIM card, the phone asks me for the 8 digit SIM unlock code, so I entered the 8 digit PUK code provided by Vodaphone with the SIM. The phone tells me this code is invalid. I'm not quite sure why this isn't working - is it possible I need to load a different firmware to use the phone in New Zealand?
Kernel is 3.4.10-g31f7883
Firmware looks like 3.62.401.1
I'm currently using ViperOne ROM.
Certainly appreciate any input on this issue.
Thanks,
Josh

Well, I did not realize that bootloader unlock and SIM unlock are two different things. That's a bit confusing. Wish I had figured that out prior to flying here.

If I remember correctly (this is all from memory), for the unlock code to work, you need
1) correct (original) CID and MID
2) stock ROM (some were able to do it on custom ROMs, but not sure if all work or only certain ones)
3) stock firmware for above ROM
4) stock recovery
5) LOCKED or RELOCKED bootloader
6) S-Off won't matter, and that will be your ticket to unlock again
you can search the forum here for SIM UNLOCK, there are quite a few similar cases, which got solved by a combination of points 1 through 5.

If anyone stumbles onto this thread in the future...
Turns out I needed a code from AT&T, as I needed to carrier unlock the phone before being able to use the Vodaphone SIM. I tried contacting AT&T to get the code, but they won't give it to you unless you are out of contract.
I was able to get an unlock code using option 5 in this thread:

I loaded a stock ROM, but left the bootloader and my custom recovery on there, and the unlock code worked just fine.

HTC One Europe unlock

Hi guys,
I am writing because I have a friend in need and xda was more than helpful to me in the past. I have Samsung Note 2 but my friend owns HTC One European(probably) and the phone has a sim lock on it. It is bought in Bosnia and Herzegovina and he came to Austria to live now and phone is of course, not usable. Can you point me please to some unlock methods, free or not? Ive been searching a bit online and all I can find is unlock for HTC One Sprint. He has 4.4.2 now and update is available.

There is many threads here regarding sim unlock, use the search option. Essentially, he will need to purchase an unlock code i.e from ebay (cost between 10-20$ US). Then when inserting the new sim card, he will get prompted to enter the sim unlock code. The phone must be on stock sense rom to use the unlock code. (some users reported successfully sim-unlocking their devices using arhd sense rom)

We have already done that. Code isn't working actually. Is there any way of determining the exact model of it? I've read that some codes don't work for Telenor Serbia or VIPnet Croatia. It's not the network from which he has bought it but it's also not possible that M:tel from Bosnia changed it's model somehow.
