[Q] sim unlocking before flashing rom? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi Everyone,
I've looked everywhere and i can find the answer to my question. Do I have to Sim unlock a rogers sg3(i747m) before flashing at&t cm10 stable? I guess i'm worried that if i flash at&t 's version of cm10 on a rogers phone then it might not work on rogers?
Thank you.
Steve

No offence but you didn't look hard enough...
And the answer is yes. Unlock on stock firmware first.

Unlock

Is anyone working on no code or nv read unlock on the sim?
Yeah, I'm not sure about that but I have a related question. I unlocked my phone today on the stock rooted ICS rom. I'm wondering if the unlock will persist if I flash darkside v7 or if I will have any issues using my phone in europe after flashing a custom rom
EDIT: I actually also remember seeing a dev only unlock thread in the android development section so you might wanna check that out.

You can absolutely flash the leaked AT&T rom onto an unrooted Rogers glide, it's no different from installing it on an AT&T glide. If you're new to flashing in general, you can see my walkthrough here.
You should also be able to flash a stock AT&T firmware onto it and get the official update through Kies, but that seems like more effort than it's worth. I'd recommend either flashing the leak (and then clockworkmod and the keyboard backlight fix) or waiting for someone to release a version of the official 4.0.4 rom with the AT&T bloatware removed, which should happen soon.
You'll need to set your APN to match Rogers, or your MMS and internet won't work.
Hey thank you very much for answering..prob gonna give it a shot tonight. Gotta love paying 600 for a phone outright to get no help from your carrier lol.

[Q] flashing at&t roms on tmobile galaxy s3

hey guys just wondering if it is possible to flash at&t GS3 roms on tmobile GS3 roms. i heard you could but just wanted to confirm it.
You can. Just DON'T flash any modems from there.
If I'm not mistaken, you can flash any ROM from any of the US variants. Not everything will work right, but it works.

Help needed after much searching

Hey Guys,
New to the Note II, and have been searching and searching, and have a few questions, as I really want to get started and use my phone. Have spent hours trying to search.
1- Is the bootloader unlocked from factory?
2- Can I debrand the phone or flash a "stock" samsung firmware without any of tmobile restrictions and apps? Please guide me on where to find the stock samsung build that takes out all tmobile stuff.
3- I heard tethering doesn't work if I use a non-tmobile SIM. Is that true?
Thanks for all the help!
Yes the bootloader is unlocked and the rom im using jedi x8 which is based off of the international one...so I im pretty sure all you do is flash the tmobile radio

ROM/Radio for unlocked T-mobile s4?

Hello,
Recently my friend gave me a T-mobile S4 which I successfully unlock using this ( http://forum.xda-developers.com/showthread.php?t=2283068 )method. I aslo was able to install Chaos (universal) ROM and seems to be working fine, but I have a few questions.
Can I install an ATT ROM/Radio or I need to stick to universal ROMs?
Can I lose unlock status if I upgrade the radio?
TIA!
Anyone?

I've never tried ATT ROMs and haven't seen much mention of them in this forum, but I know i9505 ROMs usually work if the developer hasn't put specific device checks in the updater-script. I would guess ATT ROMs will work as well. You may need to flash a T-Mobile kernel though. Radios that are not specific to your device should not be flashed.

Why would you want an ATT Rom or radio? The Tmobile radio package supports more frequencies than the AT&T version. I am currently using my M919 on an AT&T mvno and my girlfriend has the I337 (AT&T S4) so Ive switched sims around on both and could find no significant difference.
