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.

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.

Here's the story,
it's been literally a whole month I've been looking throughout the forums for a way to simply unlock my bootloader for my HTC Glacier.
Previously, my phone fell into a puddle of water about 4-5 months ago so I got a new replacement with something labeled as "LOCKED" in the boot screen, which I had no idea what it was. So, I keep't requesting replacements, and I received a new one every time with a locked bootloader! I realized I couldn't/shouldn't unlock through HTC Dev because of all the consequences, so I just looked through just about every post on here about the MyTouch 4g on how to unlock it, and even trying HTC Dev when I became hopeless about the issue, it didn't even work! I'm STILL stuck on stock rom, stock everything, and with a LOCKED BOOTLOADER!
PLEASE, if anyone can help me in any possible way, I would be the most appreciative of any person on the planet! If you have the slightest idea on this issue, please comment below, message me, or something!
Thank you..

Does the standard downgrade procedure not work for you? When someone with and htc-dev unlocked bootloader comes in here we tell them to relock, dowgrade and use gfree to get S-Off.

Well if I didn't state it correctly, I am still locked. The downgrade I'm sure would work just fine if I could unlock, and I also cannot unlock through HTC Dev; during the fastboot commands, it does not allow me to flash the unlock code.bin file. I don't think there is a possible way for me to unlock this bootloader, which I'm hoping to find a way asap..

You didn't read me correctly. SKIP the unlock and downgrade then use gfree to get S-Off. The downgrade method predates your bootloader but still works with it as long as it's locked. S-Off gives you full access. An HTC-dev unlcked bootloader sucks butt. Also, your red text was rather unecessary.

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

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

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...

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

You cannot unlock the bootloader. You can still flash roms with ss but not kernels. Odds of the bootloader ever being unlocked are extremely slim to none. The dev edition comes with an unlocked bootloader.
Moved to Q&A forum.

Yes this is Q&A now because your thread was moved from "General" and I posted it when it was in that forum
say what
I posted that in General?? Then my bad, I didn't realize that I had done that
Actually been looking for info on this matter. Being that I am stuck without the dev variant for the foreseeable future, does anyone know if it is being worked at the moment? I understand the chances for an unlocked bootloader just curious.

I want to root my Razr M and need assistance as I've never rooted a phone before. Could someone link me a safe guide that I can use? My phone is that "Not for sale. Motorola Mobility Confidential Restricted Property" version and it apparently can't seem to detect any kitkat update(even though razr m has the update). So I'm going to root it and update it to kitkat. I'm not a noob per say, just that I haven't ever rooted a phone and have least bit knowledge about cellphones.

Everything has the potential to go bad. So, if you're not willing to accept that, modifying is not for you. With that being said, Sam's update is easy to use if you follow the directions. Once updated, root and unlocking the bootloader are also easy.
