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.

Hello everybody,
As i don't have enough messages to answer on the development thread, i post a few information here.
On my Z bought on a xperia store (lock bootloader but unlockable, french version (I think it is a worldwide one...) ) i runned the exploit, and it do work!
But as some comment said, the NFC stopped to work (only bug so far...).
The error is simple: you can't 'check' the box in configuration.
The logcat is simple and say only a few information:
I/NfcService( 1102): Enabling NFC
E/NFCJNI ( 1102): phLibNfc_Mgt_ConfigureDriver() returned 0x0106[NFCSTATUS_INVALID_DEVICE]
W/NfcService( 1102): Error enabling NFC
I don't know if i can help. But here are the few informations i have =)

SuperUser is there, just no apps have root access. None.
In process of flashing back to stock and going all over again.
EDIT: restored with SUS and rooted again with this method. All seems good so far.
Thanks for the tip, it works like before now.
And root is correctly working

Worked like a charm, and thanks for the tip to fix NFC! This is very valuable to me, my bootloader isn't unlockable (I'm hoping a carrier unlock will help there, but Vodafone Ireland claim they don't have the NUCs yet).
AW: About goroh_kun & huhka_com exploit on C6603 / 10.1.A.1.350
No, wont help. An unlock blocked bootloader is locked for good. No way around it and I judge from your post, you dont read other threads so you have no idea whats going on: Sony - as other manufacturers did and do - didnt compromise Qcoms security installments in place by poorly engineering the phone. Bootloader security barrier most likely wont ever be broken through.
How exactly do you remove a directory like that?
Use root explorer.. Worked like a charm
I didn't remove it I just renamed it to usf1 it worked! But there are a lot of files in that folder. Is it not important?

I take it your talking about official bootloader unlocking? Coz obviously a dev might work out how to unlock a bootloader using other ways which would mean a blocked bootloader can be unlocked.

Hi everyone
I'm new at this root things so I would like to make a couple of questions if you don't mind...
I have a SIM Free UK Xperia Z, so I think my bootloader is unlockable. The thing is I don't want to do it (at least for now) because I will loose DRM keys, BE2, and my warranty...
1- Can I root using this method without unlocking the booloader?
2- If I root my phone with this method I mantain my DRM keys, BE2 and can restore it like when it came from factory?
Thanks in advance
1. Yes
2.Yes

I covered this in my initial post: recognized elite Android god Entropy512 himself, stated repeadetly, that bootloader security on Qualcomm devices is very strong. If it gets broken (this is what you ask/hope for) then it's usually because the manufacturer ****ed up Qcomms security. Sony, so it seems, does not have done that so an "unofficial" unlock or "bootloader crack" is very unlikely on the current devices, such as the Xperia T and Xperia Z.

Most likely, yes. Or better: usually, yes, exemptions exempt. You will be able to update and keep root using the help and procedures which will be published in this forum.

Make sure your file explorer is configured to access system directories (such as /data) in root mode. You may need to change a setting to enable root access.
/data is definitely not empty, it's filled with plenty of other stuff.

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.

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.

Hi Carbon, I cannot confirm if it give full root access on locked bootloader, however I am now on locked BL (relocked using Flashtool). And it's working as per, well, usual.
As mentioned in OP, I am not a dev nor am I fully aware on how partial root access will be like. At the moment, if you're referring to something like - locked BL not able to install Dual Recovery, it probably is as I'm not able to install any recovery at the moment. Troubleshooting with NUT and with unlocked BL (will update tomorrow on this, it's bed time.)
Edit : Chances are it's partial. Will look into this matter tomorrow. More updates to come tomorrow.
I wanted to know for those with locked bl do they have to unlock then relock boot loader?

Apologies but can I know which part is a repost? I mean, I went through these steps personally without following any guides out there. I simply made my own guide as to post in my local forum however, thought it would be great to at least share the method for .290 root, is it wrong to share some info on how to keep/retain root? Also, I am not very sure if I see any guides that gives such information here on xda yet. Krab's rooting guide is for the older firmwares.
I simply used what resources available and give it back to the community. I'm sorry if this upsets you. I'll remove op if you insist that this is a repost.
Hope to hear from you soon.
the files you will need: MUST PATCH FILE.zip
but in the tutorial, you do not explain when to use the patch
I am on 4.3 and I didn't backup my TA so this thread do not help much. Nothing what I already know.
C6903_14.2.A.0.290_Stripped.ftf from installing flashtool stays in a loop and it's not sony's image and restarts again and again.
In the links you put the file is a zip C6903_14.2.A.0.290.patch but *. With flashtool can not flash.
Greetings.
Why are you attacking this guy?!
Oh no, he opened a thread - unlike many other guy who open threads just to say we have new update in update center - this one is really good and smart one.
Of course something will be repeated but this is a guide and NUT has ROM, that's the difference.
I must agree with some comments - XDA for Z1 isn't good, all the time we see bad comments and very little development.
In Xperia S section we had so much fun why can't we have that here?
Atmosphere just isn't right....
For a days I'm trying to force my self to do some theme MODs but if I'll get this kind of "tnx" than I'll keep it for myself.
We have great guys here, awesome MODers and DEVs let's show them a bit of respect and if something they made isn't for you - just skip it, don't spit it.
Moderators are here to say what's junk and what's O.K, I agree with @gregbradley - way toooooo much of "how to" that aren't finished but this guys are trying their best to help you.
So...tnx to @8geek and if someone knows better and can give us full root on 290 - awesome, let us see that...

This will now work on model versions C6902/C6903/C6906/C6943

At the moment, I think that the only solution would be to backup apps and games is using an app called Helium. As far as I know that is the only working solution available on the market. Users have reported that the free version does not always work properly and that the safest would be to use the 5$ premium version of the app and to backup to a cloud storage, so I would recommend buying the premium app. Here is a link to the app:
https://play.google.com/store/apps/details?id=com.koushikdutta.backup.license&hl=en
You can backup your photos by either choosing cloud synching in Google+, Dropbox or any alternative storage or by transferring them over to your computer.
https://play.google.com/store/apps/details?id=com.dropbox.android&hl=en
https://play.google.com/store/apps/details?id=com.google.android.apps.plus&hl=en
Don't forget to backup your text messages as well. The following app works well:

And also any saved wifi networks using the following app:
