Hello all,
Just a quick rooting question. Is there any reason to unlock the bootloader when rooting? According to some stickies, we can root without unlocking and I was able to root my friend's Captivate without unlocking anything. I am assuming we're unlocking the bootloader since it makes the rooting process easier as a hack isn't required? Thanks!

It allows you to flash a custom recovery image to go ahead and flash a custom rom and radio

Hi Dave,
Thanks for the info, but why didn't I need to unlock my friend's Captivate? We were able to get Clockworkmod Recovery on it without unlocking anything. Thanks!

The TL;DR of that article is that,
Every phone has a bootloader. The Nexus series (and now Sony Ericcson after filing out a form on their website) has a unlockable bootloader without the usage of any exploits. Phones such as the Galaxy S series (Vibrant, Captivate, Epic 4G, etc) -- mainly Samsung phones have weak bootloader protection.
HOWEVER, all of the other phones' bootloaders are unlocked due to a exploit. So yes, your friend did unlock the bootloader without actually knowing it.
The only phones that are unable to unlock the bootloader are Motorola phones because of the bootloader being signed.
But if you really want to know about bootloaders, read that article.
@dave: there is no such thing as a custom radio. The radio itself is not open sourced. But it allows you to flash a older version of the radio since results of radios vary between user. Some people may experience better connection with KB3 than KD1 and etc.
Thanks! It was as I thought.

Correct. Most other phones require an exploit to root, the Nexus S does not - if you unlock the bootloader. Conversely, you might still be able to root the Nexus using an exploit, even if you want to keep the bootloader locked.

I have a related question. I relocked my bootloader after rooting. What exactly can I not do with it locked?

It's kind of a PITA to flash an updated Clockworkmod Recovery. That's all I've found out.

^ but to be honest, not to many things get changed within the recovery. Sure the modified Clockwork recovery gets updated. But the original clockwork from ROM Manager doesn't.. it'll work, but I don't see a reason on keeping the bootloader locked. No security is ever compromised.

Funny, I actually paraphrased the OP. He was on the right track anyway, just needed some confirmation, not a whole paper Also there's a lot of stuff in there I don't really agree with all that much.

Flash (and probably boot) stuff via fastboot.
As stated, does unlocking the bootloader always wipe the device?
It did on mine. All unlocking guides have shown it to do that.

Wow, that blows. Well, I guess I am going stock for a while XD
Haven't got my nexus 7 yet, but I'm wondering why people say to do an OTA update before rooting. That's pointless if unlocking wipes the OS, as that's the prerequisite to root a device isn't it.

I don't understand this mentality. Just do it so that it's less of a pain down the line.

Doesn't wipe the OS, it wipes data (but not /sdcard); it's like a factory reset.

I unlocked the bootloader, relocked, and unlocked in a space of time.
After unlocking for the second time, EVERYTHING was gone, but my build.prop wasn't touched and I still had 4.1.1 (that I updated over OTA)
I just bought a Nexus 7 today and as soon as I setup the wifi it's prompting me to update to Android 4.11, it has 4.1 on it at the moment. I want to root the tablet but having use the Android Gingerbread in the past it is a PITA to wait for new root after we updated OTA on our smartphone. Should i avoid any OTA update for the N7?

Is there a new way to unlock 4.1.1? I'm new to rooting and stuff and I don't want to take any chances so I wanna be 100% sure.

It's a nexus. The answer to that is ALWAYS yes.

There's never a new way, it's always the same way. No update will "break" this.
fastboot oem unlock to unlock (this only have to be done once, it will remain unlocked unless you manually re-lock it)
fastboot flash recovery your.recovery.image (to flash a custom recovery)
Boot into recovery and apply the su zip of your choice if you merely want to root or if you want to flash a rom the rom of your choice (assuming these already reside on internal storage).

If you don't mind, I'd rather actually root my nexus s instead of my brand new bought nexus 7... I'm assuming it's almost the same guide to root both; just a different file; do you know of a guideline to root the nexus s on 4.1.1?

It is okay to use. BUT...it is always best to learn how to use adb. You know, just in case something ever goes wrong.
It is not like Apple's device, you will always be able to root and all, you dont have to be scared

I really like Wug's toolkit, I know there's a few so I'm not positive if the one you're referring too is wugs or another one, but I reccomend using wugs, and following its step by step on setting up drivers properly.

Have installed the 4.2 update via recovery and locked the bootloader. Will I now get future OTA updates from google?

The bootloader being locked or unlocked makes no difference. We typically see people OTA update fails from people who have modified system apps/files or installed a different kernel.
Ah ok. I had previously rooted it. But decided to revert back now that I have installed 4.2

Unlocking Bootloader
So, can you unlock the bootloader on 4.2? Or does it even matter on what Android version you are on?
Thanks and Cheers!

Yeah, but is the method for unlocking it on 4.2 different from the method on 4.1.1?
Sorry Im asking all these questions, rooting is a bit different from jailbreaking lol

Haha, no. The method is still the same. And I suspect it will be the same for a while to come.
Oh and welcome to the Android world
The bootloader is unrelated to the version of Android you are running.
It is a " boot loader" that runs before the operating system is loaded.
Unlock it once, when you first get the device - and it should stay unlocked forever.
Nothing to do with root either - except the bootloader has to be unlocked to root the device.
Root and unroot the device as you like - just never mess with the bootloader after you unlock it.
Unlocking purges all your files...

It hasn't changed since the first Nexus device and won't be changing any time soon.

NO, I meant AFTER.
See actually I rooted my phone through framaroot and boot unlocker it took hardly 5mins.
Root through Framaroot and then I unlocked the boot as it was giving a message "Waiting for root access"
Don't know about Toolkits. Sorry.

its two different types of unlocked. the nexus 4 is carrier unlocked, no matter where you buy it. but if you are unlocking the bootloader, thats a completely different thing that you are unlocking.

One more question does rooting with tool-kit and giving the device superuser cause issues with updates from google?
I really don't wanna run a custom rom.
also if I check the button USE CUSTOM RECOVERY it will use CWM right?
If u want OTA, don't use custom recovery. Only unlocking and rooting don't mess with OTA.

This is wrong having a custom recovery will not prevent you from receiving or installing the ota update. Its actually better to use a custom recovery because when you update it breaks root and twrp will ask you if you want it restored
