No. A custom ROM wouldn't lock or unlock the phone. It can be unlocked for any SIM and still be stock firmware, it can also be unlocked for any SIM and have a custom rom.
The two things are completely different.
Hope this helps.

You can do whatever you want to any rom, and that won't affect anything that makes it unlocked

thx for replying,
so meaning, currently the phone is unlocked, and i downgrade to RC29
so it wont be locked again ?
because need to downgrade to root-ed the firmware....

is this mean, downgrade my unlocked phone firmware to RC29
in the process, it will not reset my phone from unlock back to lock status ??
if it will not make my phone locked back again during the process
and i success downgrade to RC29 i can gain root access, then i can update to custom firmware
so another question, in the upgrading process (flasing to custom firmware or cupcake 1.5) will it set back from unlock to locked ??
sorry for my bad english
appreciate for replying, i need to know before i done anything
in the process,

Hi. I also have an unlocked phone. It was unlocked prior I downgraded it, and flashed new custom roms, and it is still unlocked. As the others said no need to worry, if i'm right the locking thing is in deeper level. Of course everything you do with your phone is your responsibility.

Can T-mobile still unlock the phone after I rooted it or would they know that I put a custom rom on it??

Yes, you can still unlock it through T-Mo. No one at T-Mo needs to have physical access to your phone, they can give you an unlock code over the phone.

One has nothing to do with the other. ROMs have nothing to do with the SIM cards and SIM cards have nothing to do with ROMs. T-Mobile isn't going to come to your house and spank you for having a custom ROM because they "know"

Why unlocking befor flashing?

I want to flash my samsung with the newest firmware from "samsung-firmwares",
but why i have to remove before my simlock (it´s a branded from A1).
And what happens if I flash without removing the simlock?
Thanks.
I also have the same question on my thread, no body seems to know if we can really flash simlocked units.
errors on boot i suppose ?
So Android phones actually combine simlock with different firmware locking (CID lock?) ??
The hell with that, then. In any other phone we can flash the firmware without the worry about simlock.
i rooted mine and it is sim-locked. never tried to flash tho.
just chiming in that we need some sort of confirmation/assurance that flashing is/ain't possible.

i got the same qeustion, mine is root as wel but can some1 confirm that we can flash the phone when its locked?
and is there a way to check if your phone is simlocked??
Mine is SIM lock (i think, never tested) because it was A1/Vodafone branded when i bought it..
After flash the brand was gone, but dunno with the simlock, as i have A1...
you can flash a locked phone without any problem. it will stay locked though after reflashing. if you flash a generic firmware you will get rid of the carrier personalisation.

Im think if you have it unlocked and you install a custom rom, it wont lock it again. if its locked and you put a custom rom, im sure it wont be unlocked

No, it will not lock again. Just be prepared for a lengthy bit of research should a custom install goes awry. Backup, backup, backup.

[Q] I'm rooted and SIM unlocked, BUT!

I have lost my unlock code due to a HD failure. I am currently rooted and unlocked, and I run the leaked Froyo ROM.
What will happen in the future, should I want to flash, say, a Cyanogen ROM (*if* it becomes available)? Will I lock again? I understand my unlock codes were wiped when I flashed the new ROM.
Is there a way to insure I do not become locked again?
I have searched threads extensively, I do not think I have found a consensus on this? Anyone care to enlighten me?
I unlocked back on 2.1 (JF6), updated to JH7, flashed 2.2 (JI6), and have also flashed Cognition Betas 6, 7, 8, 8.1, and 9...and I'm still SIM unlocked. As far as I know, it's permanent no matter what ROM you choose to flash.

That's what I did before I got my SIM locked, was playing around with JH7 a month or two back and somehow got it relocked.

Hmm...strange. I still have my code (saved on both my MicroSD and an external harddrive) but I might start removing it as a precautionary measure.
even i never removed my sim anytime while flashing or updating....mines still unlocked....i hope it doesnt get locked in the future, cant we permenantly unlock it. . . .

Thanks for all the info. I feel better now! And yes, I will remove my SIM before flashing

Questions From a Would be Owner

Hello guys,
Just a few questions so I know what I am getting into
1) The phone can be rooted. However, if i want to run on a custom ROM or use mods such as the music mod, I would have to unlock the bootloader, yes?
2) Once the bootloader is unlocked, I would lose the 'Bravia Engine' feature of the phone. What else will I lose? For those who have lost it, is the trade off, of being able to run Custom ROMs and mods while losing the 'Bravia Engine' feature worth it?
3) If I have to send the phone for warranty, I could just re-lock the bootloader and send it back for warranty. Is there a chance somehow that they'll reject the phone if they detected that the phone's bootloader was tempered with?

No clue since mine isn't/can't be unlocked. The only reason for me to unlock the BL (Even though it can't be done) would be, to flash a custom kernel, beside that I don't see any other reasons why I should unlock it.

Once it's unlocked there is no way back.
So if you want to root your phone, use custom roms (without custom kernels) you don't need to unlock the bootloader.

Thank you very much for the reply.
I assumed as such from reading some posts initially, but then I went to the ROM section (If i am not mistaken) and there is a post on how to unlock the bootloader and then there is the Why section where it says that you could then use custom ROMs and mods which then confused me.
If i can use custom roms and mods without unlocking the bootloader, then I'll definitely be getting this phone.
I'll take advantage of this thread to ask one simple question: once we rooted the XZ and flash the Mods we find useful, we no longer get updates from the official Sony firmware in the future, right?

First backup your firmware with http://forum.xda-developers.com/showthread.php?t=2188129
You can go back at any time to your original firmware and you can have the updates via pcc or sus.

TWRP and ROMs for Note N920A w/ Nougat

Can I install TWRP for the AT&T version with Nougat? I have heard that if I try it will brick. I'd really like to install a new ROM so I can get rid of all the crapware that comes with the phone.

The 920A At&t cant be rooted as of yet and no twrp because the bootloader is locked...
Bootloader
I recently talked to at&t about getting my bootloader unlocked and a supervisor told me the only way to do so without bricking would be to being it in to an at&t store and they will unlock the bootloader.. anybody else have this told to them?
They're most likely taking about a Sim unlock not bootloader. Also there is a method for rooting it but you have to be on a specific bootloader and you can only use it on lolipop.

Ya, I know about that root method. Unfortunately, my phone decided to update itself a few weeks ago and now its on BL 5. So that's pretty much a no go.
In relation to bringing in the store for a BL unlock, I did specifically ask and made sure the tech I was speaking with knew the difference between BL and sim unlock. In fact, i made it very known that my radio was already unlocked, I done that weeks before i talked to her.
