Do I have to unlock the bootloader before install TWRP? Cause I rather not have to install/setup all my apps again.
Also I'm on Boost Mobile, if that matters.

Yes, you have. If you don't unlock it, you can't flash anything.

Back in the days before the unlock tool, and before I got my Prime, I have a vague memory of checking this forum and there being ROMS that could be installed without unlocking or using CWM.
Anyone know if there any of these still out there, or if you can somehow convert existing ROMS for use without unlocking?

You cannont flash a custom rom without being unlocked and having a custom recovery (cwm, twrp). The stock recovery will only flash roms signed by asus. So it is possible to downgrade or flash previous asus provided versions of android using the stock recovery if you are rooted. There is a thread on how to do this in the development section.

Yeah I'm rooted. Just wanted to check out custom ROMS but I'm scared of unlocking because of the warranty implications. Didn't think it would be possible, but my vague memories of seeing custom stuff before unlocking was possible prompted me to ask.
Did I dream this, or was there some limited customisation going on before we could unlock?
Okay, im new at this android stuff and im gonna say "sorry for my bad english" before i start to write it.
I just unlocked the bootloader and i did setup the "Advanced Stock ICS Kernel"
The Superuser app works great. (I think i might open root access(And thats what my purpose to do all that things.))
But, i just wanted to ask some questions. So;
1-) I have to lock the bootloader again? Because i saw something in internet named "Installing app's with unlocked bootloader is dangerous."
Is that true?
2-) If i lock the bootloader, will i still be able to use root access?
3-) The cellphone says "A new system upgrade is available" if i upgrade it, i will lose my root access? (And the upgrade is same with my version.)
Can i delete that reminding from the top of the screen?
You don't need to relock.
It also shouldn't tell you of system updates if you're unlocked?

I meant following the unlock instructions from the Sony website.
I want to reinstall cyanogenmod/aokp and use CWM that cm came with this time!
Thanks!
No. Once you unlock your bootloader, it doesn't relock until you do the process.

Reading a few articles here on XDA and a few outside about the general process of rooting and unlocking bootloader, here are a few things I have learnt (question is below) -
Usual steps to root -
1) Unlock bootloader or bypass bootloader.
2) Install a "Custom Recovery". Eg : CWM, TWRP.
3) Push(or copy) a binary file "su" to the "root" of the device using this "Custom Recovery".
For the Nexus, HTC and Sony devices, the first step (unlocking the bootloader) can usually be found on the website of the OEM itself.
It involves using "adb" and "fastboot" executables provided by Google.
BUT Samsung does NOT have this procedure.
Instead, MOST rooting procedures I have seen, use ODIN.
And the first steps are -
1) Boot to "Download mode"
2) Install "Custom Recovery" through ODIN.
So what EXACTLY is happening to the bootloader?
Does ODIN unlock the bootloader in Samsung devices?
OR is it just bypassed to install a Custom Recovery?
I hope this is a valid question!
And sorry for using all the quotation marks. I just wanted to highlight a few things and HTML tags for bold and italics are not working for me for some strange reason.
I love wrongly used quotation marks, some great websites for that!
With rooting every device is different and most Samsung devices do not need to have their bootloader unlocked. Its not better or worse just different. It's all about how the oem writes the firmware, Samsung just often doesn't have this, which also is why those same devices don't allow for fastboot commands, not written into the code
If you are asking how to root your device I would need more specifics on what it is but just know that unlocking the bootloader is not always a prerequisite.

I recently rooted my SGH-I577 and flashed CM11 on it.
Thanks to InkSlinger420!
In the process, I wanted to get a general idea of what is going on instead of only following the steps.
So I guess my Samsung phone is rooted but the bootloader is NOT unlocked?
And sorry for the quotation marks again.
I can't get the options on the top of the edit text message box to work. Like Bold, Italics, attach, hyperlink etc etc...
They're just thumbnails
The smilies on the side too...
Off topic, but help?
Wasnt picking on you by the way, just saying how fun it is to read sites like this
http://www.unnecessaryquotes.com
But to answer your question, you device doesn't have a step to unlock the bootloader in the rooting guide because it isn't needed. In a sense it is unlocked. The reason other devices need you to unlock the bootloader before root is there isn't another exploit to bypass the security checks done by the bootloader (and sometimes radio) so in order to root one of these often the first step is to unlock the bootloader.
Your bootloader doesn't run these same checks and so there is no need, again not necessarily better or worse, just different

Gave me a laugh, that website! I'll refrain from using quotes.
Thanks!
Have a better understanding of the root process now! (I think)

Hi first post. Have just got a z2 from Vodafone which has a locked boot loader now I know this stops me installing custom roms and kernel but will I be able to install stock roms. Mine has come with loads of bundled Vodafone apps and bloatware so want to be able to install stock UK rom. When there available as the battery performance seems to be badly affected.? Thanks
Yes there should be no reason why you can't use flashtool to debrand with an official signed stock Rom.

With HTCs there was a CID number which blocked official RUUs. Are Sonys like that at all? It stopped my friend upgrading to jellybean with the official RUU for ages.

Any stock based ROMs can be flashed on devices with locked bootloaders... This includes official Sony firmware, such as that from other regions (you'd probably want a generic version to avoid bloatware), and developer ROMs that are based on stock. Familiarise yourself with the latest flashtool as this will be your go to software for flashing.

Can someone explain exactly what we can/can't do with a locked bootloader?
Mine is locked, and not unlockable. Can I still flash a non Vodafone/generic Rom? Can it be fully rooted? Can I install different ROMs?
I like this phone a lot, but have until the weekend to decide whether to return it or not. If I can still root and remove all the unwanted apps/bloatware, I'll keep it

You can currently root the device, install the (one and only) current custom ROM, remove all bloatware and such just as you would any other phone
BUT
In order to do this the current method involves unlocking the bootloader first before obtaining root access which will wipe the TA partition, thus losing your DRM keys.
You need the DRM keys in order to restore your phone completely back to stock in order to get full warranty...
So until a root exploit is found which doesn't involve unlocking the bootloader first you can't uninstall apps without worrying about warranty - however you should be able to disable them from the app settings menu
Hope this helps explain things better for you

I'm in the same position mine is from vodafone uk, and has a locked bootloader. When a generic stock rom is out can I flash it as normal, which will then remove just the network bloatware?
Thanks
Thank you everyone who took Time to reply does anyone know how long it will likely be before a UK stock rom will be available and where would I likely find it. Thanks once again we
Dial *#*#7378423#*#* and under service infor there's configuration, under that does it say Bootloader unlock allowed: No?

At this moment in time there is no known root exploit so without boot loader unlock all you will be able to do is flash official Sony signed Roms. They can be for any region and any carrier. You won't be able to root or install custom rims.
Once a root exploit is found for any official Rom you will always be able to flash that Rom and gain root which will allow you to install some custom roms that are based on stock and use the stock kernel. You will never be able to run fully custom Rom images like cyanogen as they use custom kernel's which require an unlocked boot loader.
