Dropped down to jelly beans to SIM unlock a phone for a friend. Got it to unlock and work fine, My question is after i do this can i up it to KIT-Kat and if i do will it keep the unlock?
Thanks
Once the phone is sim unlocked, it will not relock even after flashing ROMs and bootloaders.
I unlocked two note2 and three s3 and all five phones remained unlocked after upgrading to 4.4.2.

Is there a way or app that I can use on this phone so that I can view my SIM Unlock Code AFTER the phone is already SIM Unlocked?
I ask because I bought two of these phones unlocked and would like to have the Unlock codes saved just in case I need them later.
Somehow I seem to have messed up or lost my unlock on one of the phones after I rooted it and flashed a new recovery / rom.
It was unlocked, now, If I put an ATT sim in it asks for my unlock code again and I do not have it, as the phone was unlocked when I got it.
Though, when I press *#7465625# to it says all the locks are turned off, like my phone should be unlocked?
Any idea why it is asking for my unlock code again, and if there is a way to get around it being that the phone was unlocked?
Is there a way to recover this unlock code?
Thanks guys!

Currently there isn't a way to view the code. Several of us have been digging through the system of the device to see where it's coded too. the thread here is where it's being conversed about. click here
How do you know for certain the phones were unlocked when you bought it? Did you try swapping Sims before you flashed anything to it?
I have mine unlocked and have flashed; two roms, cwm, a radio, and a few mods......still unlocked. I constantly swap Sims between my crap work phone and my Samsung, always works.

The person I bought both phones from told me they were both unlocked.
The first one I tried worked, the second one I never tried an ATT Sim until after I rooted, flashed, etc and then it wouldn't work.
He emailed just emailed me the Unlock codes for both phones and they work fine.
Either way, it's all good now. Thanks for the help guys!

Good Day
Sorry if this question was asked before, I am not clear about flashing new ROM.
I have a locked GN3 from tmobile, I bought unlocked code from eBay and my phone now working perfect with international career.
If I flash new ROM 4.3 or 4.4, will it be locked again? if tmobile release new update KitKat 4.4, should I update? re locked?
Thanks
Flashing any rom will not lock ur bootloader. Once u unlocked ur boot loader, unless u lock it back. It will not be locked by flashing roms etc

OP...I used Chainfire's RegionLock Away App on my rooted T-Mobile Note 3 and had to Odin back to stock for some troubleshooting and it was still sim unlocked. Once you sim unlock it once you should be good to go from there on out.

He's not talking about his bootloader, he's talking about the phone being sim locked to T-Mobile's network.

Thanks again.
I have an ATT phone currently unlocked and using it on T-Mobile. I want to root and use it on T-Mobile, but Im a little nervous that once I root, and wipe everything, the phone will be re-locked to ATT. So my question is, once I root will I lose my carrier un-lock?
It might be helpful to clarify a couple of things. It sounds like you're currently SIM-unlocked (thus able to use your AT&T branded M9 on T-Mobile). Are you currently bootloader-locked and want to unlock it so you can root? Or are you already bootloader unlocked?
Rooting definitely does not wipe/re-lock anything. Unlocking your bootloader triggers a system wipe. My understanding is that once your phone is SIM-unlocked, system wipes don't affect your phone's SIM status.
Sorry for the confusion. I am currently sim unlocked, and I want to bootloader unlock. However, before I unlock my bootloader, I want to make sure that I wont re lock my sim. My ultimate goal is to unlock bootloader in order to root, but I dont want to relock my carrier to ATT. Yes, it is an ATT phone and I'm using it on T-Mobile.
I'm pretty sure that unlocking the boot loader will not affect your SIM-unlocked status.
But if it were me, I would want a more definitive answer than that.
Another forum member may be able to answer for sure. In the meantime, consider asking HTC directly via their chat system. I've found them friendly and straightforward.

No you won't lose your unlocked network status.
The unlock once done is permanent.
There was one a while ago on the s3, an app, which was unofficial and I lost that a few times between flashes, but I don't think you'll have that issue.
Thank You. Unlocked boot loader, rooted and still have sim-unlock.
Does anyone think it is possible or likely that LG will allow unlocking the bootloader on Verizon/ATT/Sprint variants of the G4. They have already released a method for doing it on the European model. Any insight is appreciated
It's up to the carrier, and they all are pretty picky so it's doubtful.
I want an unlocked bootloader for my H815T, but with zero information from LG I have no idea if that will ever happen.
Do we know if anyone is working on an unofficial unlocked bootloader or workaround?
Has a US/Canadian carrier EVER unlocked a bootloader on any phone?

Tmobile is the only US carrier that does not lock bootloaders on all devices. Sprint seems like they can or can't make up their mind. Verizon has locked bootloaders forever it seems and AT&T just started it the year the Galaxy S4 came out. The GS3/Note 2 were the last AT&T Samsung devices with no locked bootloader.

HTC always leaves bootloader unlockable on AT&T (unless something changed) it was like this up until my m7 at least but I'm pretty sure all of them can be. Other than that... nope
as the title said , i installed a custom ROM to find my phone locked on every single SIM after that , i really need help and any advice is really welcome

Which ROM did You flash? Hopefully the one's which were developed for locked bootloaders. You can flash FTF on locked bootloaders, but having an unlockable bootloader would have helped a lot. What do You get when You boot with no SIM or with a dead SIM?
I did flash the Nature Rom (aroma) for both locked and unlocked bootloader, and i flashed two ftf files and now any rom i flash ask for sim unlocking code..
When booting without a Sim it boots normally and i havent tried a dead SIM
Is it possible that the phone was unlocked by a code in the past and when i flashed it it lost that code???

The possibility is low, since many users must have used the ROM and at least I didn't notice any SIM lock case. Maybe something went wrong in flashing. What happens when You insert the SIM in other phone? Also, since You can boot with no SIM properly, try checking if any SIM security related setting are on in phone, disable them if any and then try inserting SIM without switching off the phone.
