I have just rooted my phone. I wonder if I can unlock bootloader after rooting?
If I can, which way is the easiest way?
And also I want to know the benefits of unlocking Bootloader.
I want to add that I don't know so much about doing so complicated things, please know that while informing me.
I really appriciate your answers...
stock rom Gingerbread 2.3.3, rooted.
Rooting and bootloader unlocking are separate. Your bootloader has to be unlocked using a special code unique to your phone. The code is supplied by Sony Ericsson. It won't work if your phone is a carrier locked one. Unlocking the sim card won't enable it either. You need something called fastboot and only unbranded, unlocked phones have it.

I've been trying to unlock my Rogers Arc's bootloader for a while now and it doesn't seem to be working. I've flashed WWE firmware that wasn't Rogers branded and I still can't get into fastboot mode. Is there any other way of unlocking the Rogers Arc's bootloader?
By definition, Rogers branded phones can't have unlocked bootloaders (as I posted in the other thread, blagus is trying to work around this)
Just want to add that SIM-unlocking your phone won't make a difference either. I thought doing so along with un-branding it would allow me to unlock the bootloader, but I was wrong.

Wish it were true, but it's also bad logic.
SIM/network unlocking is independent of any software/firmware/bootloader.
The bootloader is loaded before any firmware/ROM (i.e. generic/debranded) meaning that altering anything on top of it wouldn't have an affect.
Right now, there's almost no reason to unlock the bootloader anyways. There are no custom ROMs available yet so the only reason would be to root 2.3.3 which can't be rooted with Gingerbreak.
Maybe this can help you? I haven't tried yet, but will do soon.

I need your help guys,
just got my Xperia ARC and i wanted to root it by this guide and i have a few questions:
i bought the phone from an Israeli carrier (pelephone if its matter) so in the guide i need to change the carrier firmware to the original firmware and i wander if it will void the warranty. also is there any way to change back the firmware after the change, if so then how? i searched and i couldn't find anything...
thanks ahead
The thing with Rooting a phone, is that you can root your phone and still the ¨stock¨ Arc is untouched after you have unrooted.
The flashing and rooting dont break the warranty by it self.
If you change from locked bootloader to unlocked.. The warranty is removed.
Easiest way to root is:
*Download*
3.0.A.2.181 Generic World: http://www.mediafire.com/?y9s73andrl4bllc
*Use Flashtool to Flash .181*

*Use Gingerbreak after you flashed back*

*After it have rebooted and active, go to settings and do a OTA over wireless.
This way you keep your Arc locked, nothing good comes from unlocking the bootloader yet.

That's not entirely true. You've got custom ROMs being developed; over-clock kernel just released, Recovery and what not.
Unlocking the bootloader is personal choice. I may not unlock my bootloader just yet but I can't deny that with improvements being shown, it's an increasingly tempting option. LOL!
Hello,
New to xda and the modding scene. Just got my Arc about a month ago and I LOVE it! Pretty keen on putting some mods on it but my qustion is, can I unlock the bootloader, root, etc on a simlocked phone? Mine is locked to Optus AU.

Before going nuts on modifying your phone you need to ask yourself if you want to root+unlock bootloader or just root... Not all xperia phones can have their bootloaders unlocked (if your phone was sold by a carrier i.e. branded such as Rogers then you will NOT be able to unlock your bootloader... Technically there is a test point method but it is quite the procedure compared to simply unlocking it the simple way that Sony offers). In the newbie guide it explains if you root your xperia but not bootloader unlock it you can only install custom roms for stock kernels, although if you wanted say ICS beta rom that Sony released then you would NEED an ISC kernel which is only possible to get on your phone after bootloader unlocking...

Not sure exactly where to post this as your forums are very American Carrier focused so I just went with model number.
I am just entering the world of rooting Android phones etc. so forgive my noob-osity but am eager to learn after realising this carrier phone really isn't MY phone.
I am wanting to use Chainfire's CF-AutoRoot to get root access on my Australian Vodafone GT-N7105T device however his instructions make very clear that the device will be bricked if I do not unlock the bootloader. I cannot seem to find a method of unlocking the bootloader for this specific device. Can anyone help with this?
Also just in general, some Rooting methods I have read about don't seem to "require" unlocking the bootloader or maybe haven't mentioned that it is part of the process.
Is unlocking the bootloader something that needs to be done ALWAYS when you root? I thought that unlocking the bootloader was only required if you wanted to flash custom ROMs and that having a locked bootloader did not prevent some rooting methods? If that is the case then I'm confused as to why Chainfire's CF-AutoRoot needs an unlocked bootloader as it's purpose is to leave everything stock?
Thanks for your assistance.
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.
