May I know if I got an ATT Atrix 4G and unlock the bootloader on day 1. Do I still need carrier unlock code for using other carrier?
Shoundn't be carrier lock is sitting inside bootloader originally?
Thanks in advance.
I still needed to unlock my carrier. Think you do too.

Unlocking the bootloader and carrier unlock - are two completely different things.
The only way to carrier unlock the Atrix is by typing in the correct unlock code.

carrier lock should be some kind of low level program perform carrier check inside bootloader, right? (correct me if i wrong). So, these 2 things are NOT completely no relationship. If bootloader unlocked, logically thinking that there has to be some way bypass carrier lock.

no there isnt a way as of now. you need to unlock both seperately if you want sim unlock AND boot loader unlock. one does not unlock the other, you need to do both.

Hi, I saw the news (on july) that the bootloader was cracked but then the posts about it's a lie and then the custom kernels appear and I don't know if the bootloader is unlocked or not.
My question is if there will be a way to free unlock the phone (sim unlock) shortly or better go paying an unlock code.
Thank you.
The custom kernels are here because some clever devs figured out how to bypass the bootloader to load unsigned kernels.
Apparently, Zdzihu is working with a mystery dev about unlocking the bootloader, and apparently, they have done it. Nothing has been released to us about it yet however.
Regarding your question, until the bootloader is unlocked, you will need to pay an unlocking service to sim unlock your phone. If the bootloader is unlocked, you might still need to pay an unlocking service.

Yum, no matter the bootloader is unlocked, the SIM unclocking is different and not relate to bootloader.

Actually, If you remember back to the flame war between Max and the_laser, much of the hype was about SIM unlock, as unlocking the bootloader would give us direct access to where SIM lock information is stored. I believe this is one of the reasons that SE will not unlock the bootloader, as they are in agreement with various carriers to keep it locked. The carriers obviously don't want people ditching them whenever they feel like it.
Edit:
I might have misunderstood your post. Sorry about that. But the bootloader is directly related to the SIM lock, on this phone at least, hence why I stated "If the bootloader is unlocked, you might still need to pay an unlocking service."
I successfully rooted my Atrix but since my volume up button does not work I cannot unlock it. Is there another way to unlock this phone without paying for unlock codes? I have read where at&t will give out the codes for free. Will that affect my account with them? Sorry if these questions are common knowledge but I am a newbie at this and anxious to check out some other roms.

I think you are confusing unlocking the boot loader (to install other ROMS) with unlocking so you can use other carriers besides ATT. You can buy unlock codes on ebay for 99 cents. This will enable you to use any carriers SIM card. That is where I purchased mine.

Yes, you are absolutely correct. I am confusing the two. What need and want to do is to unlock the phone so that I can unlock the bootloader and experiment with various roms. Thanks for clearing that up for me.

ok thanks,i will give thanks all for reply my question.
The phone comes with the sim unlocked. You can use it with another carrier's sim card without any extra steps. (You may need to verify compatility of the radios/frequencies).
There is a second lock on the phone - the bootloader. You will see many threads regarding unlocking the bootloader, as well as "rooting" - getting superuser access. Unlocking the bootloader has nothing to do with the sim. Unlocking/locking the bootloader will not affect the sim card lock (or lack thereof).
It is, and always will be(unless Verizon tries to update it and lock it down), sim unlocked. So you can use any sim in it.
But it is not boot loader unlocked stock. You have to do that yourself.

thanks my fri.
What exactly am I blocked from doing with a locked boot loader? There aren't too many roms out there for my Stellar... I figure I'd try to port one from an SIII... but with the seller's locked boot loader could I even get that far? Or is it stock Verizon roms or nothing?

You can't use custom kernels (anyway, you can use custom ROMs).
it restricts write access to some places
I am scouring everywhere for a way to do a sim unlock (i'm assuming this is the bootloader?) my boss sent me a new one of these and I live in a place where I have NO access to Verizon.. and if I don't figure this out i'll have a wifi capable paperweight.. I DID root the device though and put super battery saver on it.
any luck out there?
Cheers-

NO, both are a completely different things. Unlock the bootloader will allow you to use another kernel, regardless your network operator.
Some Samsung devices can be sim-unlocked for free (check Google Play), but for major of the rest of the phones, you need to paid for it.

How to check If my device is Sprint unlocked or OEM
I Is there a way for me to check if the device is SPRINT unlocked or OEM unlocked ?
I was able to stump/Bump and install other roms and I am currently using GSM Network on this Sprint version of LG.
Also looking 2know this...
How can I check if my Sprint LS990 is Sprint unlocked or OEM.
Guess if i can't access Bump screen (when device is off - holding Vol' Down+Power....when i see LG logo releasing power and immediately hold again) i am just NOT Bumped(=unlocked)?
Thanks!

Carrier unlocking and bump are 2 totally separate things. Bump referred to here, as unlocked, means you have twrp recovery, for flashing custom roms and backups. Carrier unlock means sim card port has been unlocked for use on any gsm network.

I really didnt knew that,
I do have a TWRP installed....which means it the same but different method.
I use my Sprint G3's out of u.s on a GSM/LTE network.
But i also interested to know if Sprint made them own unlock (with code...) or they did made an OEM unlock as they told,
Thanks for your help!

I dont need them...as for my understanding, if i have a TWRP it means my Bootloader is unlocked.
I think i mixed between two things:
1) Unlock to any Network by a code from Sprint to n oem by manufacturer.
2) Unlock Bootloader to install rom.
So if i can use a GSM network outside u.s = Phone is unlocked.
If i have a Recovery = Bootloader is unlocked.
Thanks!

Correct, to my understanding boot loader is not really unlocked, just "bumped".

So Sim unlock (by any carrier) & oem unlock completly are the same by all matter?
Thanks again!

so when u unlock you manually enter the apn of the desired gsm network. how does it work in case of roaming where it might have to switch to other gsm networks?
would switching to other networks be automatic or needs to be manually keyed in.

If you are on cloudy rom you dint have to worry about all these because his base rom is international it autoco figures the apn settings and selects the best network.
