i try this but still same not relocked

schaggo said:
Relocking is not yet fully and flawlessly possible.
The current method for relocking worked for some, others posted myriads about how it screwed all up. As the level of technical proficiency of those users is unknown and not really determinable, at this time is probably safe to say, it's a) up to you to try and b) may work with a certain chance or c) it may not.

There is still a possibility that it does not work with your device (right now).
If you access the service menu and look up the "Bootloader unlocked" status it should either read "yes" (unsuccessful) or "unknown" (successful) if you have used the tool.
Also note that DRM keys are not coming back, so BE2 will still be missing after a relock.

After unlock/recovery/root, how to return to stock?

Hi there!
I've unlocked using flashtool, installed CWM Recovery and rooted using the recovery-only root.
Now, I need to return the phone to as stock as possible - certainly removing root, but relocking the bootloader would be a good secondary objective.
My current plan is to use the flashtool to relock the bootloader, then use the PC software to repair the phone. Will this work?
Thanks for your help
Edit: I've searched the forums but can't find an answer, including in the starting thread - please link to a relevant portion instead of the whole thing if possible
Further edit: There's no 'relock' option in the flashtool - huh?

As of now there is no option to relock the bootloader. You can unroot the phone by simply performing a repair system command in Sony PC Companion or flashing a stock rom. This has been explained in every single rooting or custom MOD thread.

Ya you are right. Relock bootloader using flashtool and repair or flash a ftf from flashtool.
And IIRC in the beta version of flashtool u will find option to relock under BLU. And btw u won't get back DRM keys and no Bravia engine.

I don't see the option to relock anywhere - perhaps as I did the unlock on another PC?

If you can't get it to work with PC Companion use SUS (Sony Update Service which you can download from Sony's website) http://www.sonymobile.com/gb/tools/update-service/ --> for UK

You have to relock the bootloader with flashtool beta4,click on BLU.
Flash a stock rom and repair it by update service.

Thanks - I expected there to be a separate button for relocking - whoops!
I've flashed the stock ROM and that's gotten rid of the root. It also says that the bootloader can be unlocked, so that seems all perfect as far as I'm concerned. Thanks for your help, ladies and gentlemen.

Doomkernel questions

I've recently flashed this http://forum.xda-developers.com/showthread.php?t=2448613 and was just wondering can I still update via Pc companion/SEUS to new firmwares/updates without losing the kernel, root etc...like will it replace the kernel with a stock one?
I'm a noob at Flashing and search didn't really answer my question.

If you have unlocked your bootloader by the official method at unlockbootloader.sonymobile.com, then you can not use PC Companion or SEUS to update firmware.

From what you said, I understand that there is an unofficial way to unlock the bootloader and still be able to use PC Companion and SEUS to update firmware?

If your bootloader is unlocked, there is no way to use pc companion or seus to update firmware unless you relock it

Thankyou for the replies, I might try to relock my bootloader. I unlocked it through the official Sony method.

Not as far as I know. Older Xperia models had test point method, but Z1 does not have this option.

Has someone actually ruled this out? I mostly hear that people with LB go swap their phones or just make sure they're getting a UB phone in the first place. The main complication I see is compromising the waterproof gasket...

Unlocking bootloader doesn't have anything to do with waterproofness, it's something done using a computer.

Obviously. In order to access test points, the back cover will have to be removed. The back cover uses tape/gasketing to enforce waterproofing. My question was about whether someone has actually looked into a testpoint unlock yet for the XZ1.

[Q] Sony Xperia Z1 Needs Rooting?

Hi there xda community.
I have been interested in rooting my android devices for quite some time now although with my previous phone I had no such luck (given it was a Samsung galaxy s2 with that damn Australian custom kernel)
Anyway I'm here now cause all I want to be able to do on my Xperia z1 is plug in an xbox controller and use that, online it is said I don't need a root, that I should be able to just plug it in and go (with the otg cable of course) but no such luck, my phone doesn't not indicate that it's recognised, I am running 4.2.2.
Will I need to root to be able to do this after all?
My phone specs are:
Sony Xperia Z1
C903
4.2.2
8974-AAAAANAZQ-10270011-23
3.4.0-perf-g66807d4-02450-g9a218f1
14.1.G.2.259
Is this unrootable?
Thanks in advance.

Then you should search more carefully, there is no direct root like Vroot, 360 or Cydia for .290 and .136 FW. The only way to Root Z1 is with THIS method by NUT. You have to Downgrade to .534 FW provided by NUT to not lose IMEI, Root with Bin4ar, then Update first to .290 with the instruction provided, then when you have .290 rooted follow this instruction HERE
Watch the Video tutorial Hot To Root on first link.

Okay so I now have my Xperia rooted at .136. I'm hoping now there is a way to connect a wired xbox controller, but my phone doesn't indicate that it's connected. Apologies for the questions.

Good, don't forget to click thanx. :good:
About connect Xbox Controller, what I know it cannot be connected natively because is not supported. The only controller which can be connected is from PS3. But you are Rooted and I think this can pe possible in some way.
First, try different OTG cable because I got the same problems like yours with my PS3 Controller, look HERE.
Then when you have the right cable and everything should work try to follow this Thread Hot To.
Good Luck. :fingers-crossed:

One last problem, as your probably aware now that my phone is rooted ive lost camera funcion, is there a fix for this?
Also I appear to have lost data, so I cant use the internet without wifi.

Are you sure that you only rooted? Sounds like bootloader unlock to me

Rooting device won't cause losing any camera functionality.
However, unlocking bootloader on 4.2.2 will do permanently damage - I hope you watched what did you do...
Procedure is quite clear, root firmware 534, upgrade to 290 - then unlock bootloader.
Sony fixed camera broke error but it's not for older firmware.
So if you unlocked bootloader on 4.2.2 you have permanently damaged camera.
If you have backup TA partition, restore it and do everything again and try to set up your controller with this MARKET APP

Are you sure about that? Permanently? I remember people saying that they have back the camera functionality after Update to .290 or .136.

I hope he Backup TA but sound like he do not even know about Bootlader, so guess not.
BTW, I got that App and working Awesome but is for PS3 Controller, he asking for Xbox Controller, It will working too?

I'm not 100% sure, Google should know that (for sixaxis controller).
And for bootloader - yeap, I'm sure.
If doesn't have TA backup - there's no help.
Only if someone found some way to fix it and I haven't heard for that - but I doubt...

I was under the impression I needed a rooted device to use backup TA?
Can somebody explain to me what part of process I went through where I unlocked my bootloader?
All I was trying to do is root my phone NOT unlock the bootloader.
I do appreciate the help.

How?

Downgraded to NUT's 14.1.G.1.534 with flash tool rooted it with Bin4ry, installed dualrecovery then updated to 14.1.G.2.257 and finally 14.2.A.1.136.
What went wrong?

You downgraded to .534 FW provided bu NUT, Rooted with Bin4ry, Installed DualRecovery then "updated to .257", this updeate wan not necessary and instead of doing that you should update to .136 directly with the instructions from the thread, BUT this should not cause any issues what so ever.
Then you never did this steps from HERE?
Type on keyboard *#*#7378423*#* and check what Bootoader Unlock Saying, Yes, No or Unlocked?

After unlocking bootloader, whats the significant loss? Like for example, after unlocking bootloader of xperia i lost my DRM keys and then after even relocking i couldn't get them back so some Sony apps like walkman, track id were not working.
Is there anything same here on Android one also.?

Absolutely right. All "tutorials" with unlocking bootloader, formatting userdata, installing custom recovery are trash. Especially because we are going to get L update soon and custom ROMs aren't going to be the priority for a lot of people.

If you have no idea what you're talking about, why accuse someone with some idea?

Quick thing guys... Correct me if i am wrong.
When you root the device, changes are done to system and (i think) now Google as a second level checks if there are changes done at the system. If that's the case, will we get L push update with locked default bootloader and a rooted device?
Thanks.

Unlocking bootloader here will wipe all the data stock in the phone. AFAIK there is no loss over here.
You will need the stock recovery to flash the OTA update
