Why bother re-locking bootloader? - Xperia Z Q&A, Help & Troubleshooting

I dont know why some people wants to re-lock their bootloader when DRM is long gone since you unlock it the very first time. No DRM = warranty is void. Or is there something else to it?

If you want to get official updates I guess. Updates won't install on a unlocked BL.

I see. Thanks. But I thought the main reason people unlocking bootloader is because they want to move away from stock rom, no? And since custom rom is way better than stock anyway, so, I dont see why anyone would need to update via official release :/

Stock based custom roms can be installed on locked bootloader. People unlock their bootloaders to flash roms which use a kernel other than stock kernel like PA, CM10 etc. Also, just in case something happens to your phone, it is wiser to relock the bootloader and flash a stock rom and then send it for repairs.
Also, it depends on your country too. In my country although my DRM keys were lost, I relocked my bootloader and gave it for repairs. They repaired it within the warranty.

I don't think that a custom rom will be better than stock on this phone.

tbh, i feel that BE2 is horrible when browsing photos gallery. The color is just way too strong. But on the other hand, BE2 when watching a video is really nice and this is the only reason why I havnt unlock my bootloader just yet.

Likewise. There are a couple of things (and literally a couple) that I miss from CM but the Xperia software is really very close to AOSP. I'm rooted and I've flashed the black soft button bar but that's all I'm going to do until Sony release 4.2. Once that's out, then I'll decide whether I want a custom ROM or not.

How do I tell if my phone is rooted?

I bought a "rooted"phone, but I never used android before. I'm guessing the build number? Mine is FRF91. What are some benefits of rooting?
FRF91 is just the version of Android.
Best way is to see if there is an app installed called Super User. Other than that, try downloading an app that required root. Just search for riot on the market.
Search if you want to know what root is for. If you're new, I suggest not rooting your phone.
Sent from my Nexus One
OK thanks, I don't have Super User and noticed when using N1Torch it wont let me go super bright since it can't find root. So I guess not. lol. Don't worry, I'm fine for now without rooting, but I come from WinMo having ORD, so I'll need to know how to get custom roms soon. lol

Perhaps "rooted" in this case meant bootloader-unlocked then? Does your N1 show a padlock icon on the bottom of the first X screen when you boot up? If so, the hard part (and your software warranty) is already done
I know its sim unlocked, ill check for the lock now
EDIT: no padlock, good or bad?

All Nexus ones are sim unlocked.
As for no padlock, means you bootloader is locked, which is good. meaning you're completely stock.
There are methods of loading custom roms without unlocking bootloader.
Unlock bootloader (you see padlock) means your Nexus One's software warranty is void.
I don't worry about voiding warranty, that's the first thing I do with most of my electronics lol

In that case, unlocking the bootloader is by far the easiest way to hack this phone
Once you've got the android SDK installed on your computer, all it takes is the command "fastboot oem unlock" to get your phone's bootloader unlocked. How much easier could it get?
Ok great. I guess ill play around with the phone stock for about a week
Sent from my Nexus One using XDA App
You don't need to unlock the bootloader to root or flash custom roms anymore though so I would suggest using the alternative methods found in the development section and leave your warranty intact. Although most people haven't had a problem replacing their phones with unlocked bootloader there's just no point in risking it anymore because there's no need to do it that way imo.

This is my understanding too. Bear in mind that as soon as official updates are released a developer here will make it available on xda. This means you often get updates before you would normally (because they are rolled out at different times depending on carrier and region).

Once you install CWM, you can deodex your stock firmware without any problem :good:
No need to flash another ROM to do that.

Usually a carrier locked xperia has a permanent locked bootloader. Don't be surprised if you can't unlock it.
Just a heads up before you do too much research.

It is an issue if you want those highly customisable roms such as cm,pac etc. I rather lose be2 than not having the chance to flash those. But now there's a way to save your ta before unlocking bootloader so it's all good for those who want to unlock bootloader and still keep be2 for future use.

Yeah viper rom was always great in htc phones. I know not it since htc sensation. CM always seemed broken. Always something isn't working what works on other roms. I always wondered why CM always seems to have issues with things.

[Q] Is there "one-click" rooting for 4.3 (.290) firmware?

So it seems there is not simple VROOT or Kingo Android ROOT style rooting available for those who don't want to unlock the boot loader.
Anyone came across anything similar that works?
I'm aware of this thread http://forum.xda-developers.com/showthread.php?t=2588331 and the instruction in there, this is not quite the same as what I'm looking for.
Not yet.
I just want to ask this though. If unlocking doesn't break anything anymore why are you guys not willing to unlock.
On one side there are users who bash the manufacturers all year long just to get their devices unlocked, to no avail. Then some super awesome dev comes by with a Santa stick and pwns the bootloaders. (ex-AtrixHD user). And there are those who have unlockable bootloaders but don't want to unlock. I do not understand why really...This is my first unlockable phone. Unlocked my N7 2013 one month from purchase. Never have been happier.

Useless, I already tried iHackers (pre-rooted stock-ish) on locked bootloader and got partial root access because Sony's RIC is in the kernel now. So whatever you do, you will only get partial root unless (somehow) you disable it. And currently there's no way to do it with a locked bootloader.

are we likely to ever see a 1 click root for 4.3?????
4.4 Kitkat will be out soon, make sense to whoever makes these 1click roots to just wait for 4.4Kitkat.
i stuck with 4.2 for now. locked BL and nothing on 4.3 to get excited about. rooted.4.2 is better. ill happily wait for 4.4

Sorry, I'm a rookie at android devices, where can I get a custom kernel
And what do i need to do after that?
EDIT: It seems we replied at the same time! haha.. nevermind what I said below then....
Also note that a lot of our Xperia T's bootloaders are NOT unlockable. There is a code you can dial on your phone to take you to a service menu where it will tell you if your bootloader is unlockable. If it says No, then your bootloader simply cannot be unlocked. Then you can join the many of us who patiently pray and wait for someone out there to crack or work around it
