Hey guys I have some questions. First of all I own an sk17i with ics. I had locked the bootloader and flashed ics now I wanna unlock it again, should I do this via the official way or via test method. If I unlock the bootloader will everything be deleted? And if I flash a custom kernel will I be able to flash super charger script?
*sorry but I am a newbie!

If you do it with official method, you will lose your warranty, if you do it with tespoint method, you can unlock and relock and sony won't recognize, so your warranty is keepen up!
Here is the official method of sony, where you will loose your warranty.
Here you will find information on unlocking without loosing drm keys.
Unlocking the bootloader will delete all personal data, so do a nandroid backup via cwm before, so you can restore your current rom later.

If you've previously unlocked the bootloader, then RE-locked it, you need to use the official method again.
You can use the same key to unlock it as before.
Unlocking bootloader does not affect any system or data files. So no, you don't loose any data.
V6 supercharger script requires init.d. Stock kernel doesn't support that ability unless you install it.
Anyway, you can install V6 with any kernel supposedly it supports init.d.
As far as I know, every custom kernel has support...

I do not have cwm installed and that's why I want to unlock bootloader. I have unlocked via official way so I think I should unlock it again via official way.

So the apps will not be deleted? Cause the other man said that everything is gonna be deleted:S Please tell me man. I will unlock bootloader via official way, then I will install a custom kernel and finally I will install super charger
EDiT: you loose data partition so do make a backup
You can easily find a backup app on the market.
After that, you can flash a custom kernel and install V6
Official unlock method makes factory reset, so yes, you lose all data.
Thank you guys! when I will finish everything I'll tell you

so i'm about to install 4.5.91 in a few hours.. gonna backup lots of data first..
im trying to avoid bootloader unlocking for the meanwhile cause of the warranty issue and the fact u cannot re-lock.
anyway i just grabbed ATT-2.3.4_Pudding_preroot.rar and ill flash it over the gladiatrix 1.8.3 i have currently on the device (will it work?)
later i intend to use the preroot method and root and of course.. install a recovery BUT.. since the new recovery needs an unlocked bootloader.. ill use the previous one with the battery charging hack
so.. what do you think guys? will it work?

I would assume the att-2.3.4_pudding_preroot already is preunlocked (hence the pudding) which defeats your purpose?
Also, what would the purposed of the old plugged in Recovery? It won't install any of the new ROMs and I don't think the nandroid back up really works that well.
not quite.. its just have the "pudding" in it.. you'll have to perform an unlock with fastboot to void warranty.

Ok, so the other question - point of the old recovery? Just to help you wipe data/cache/batterystats?
The old recovery will still save him... You shouldn't need to be unlocked to do that.

save him from what and how? other than wiping data... he can't flash anything that can save him...
Indeed I think he can backup with old tenfar's recovery. The problem is that the sfb he wants to flash is the incorrect one, you can't use the prerooted without unlock the BL at least for the version I know. In other hand The update process is kinda complicated without unlocking the BL, if you do it OTA you will also update the BL and that one can't be unlocked now also could leave you bricked if flash back to 1.8.3.

Hello dear XDA Community,
- Xperia Z Ultra
- 4.4.2
- 14.3.A.0.681
- C6833
I have a big problem with understanding all of this tutorials. I read everything about rooting and unlocking the Bootloader.
I understood that I need to backup my TA Partition for Unlocking my Bootloader so I can continue to use Sony technology.
Requirements ? Root. Okay that was my first problem. So i looked up how to root my phone and what do i need ? A phone with a unlocked bootloader. great! Sure you can say "look at this topic and carefully read" but I really did that and I am really helpless. Thanks for any help!
What did I read ?

When your bootloader is unlocked, you can never use X-Reality and any other item which requires the DRM in the Trim Area partition,
Restoring the TA partition without relocking the bootloader will not result in the return of X-Reality and such even if you are using a Sony ROM. This situation appears to have changed since the release of 4.4.
Backing up the TA partition is only good for relocking the bootloader on a Stock ROM (any custom AOSP, CM, AOSPA etc will fail to boot on a locked bootloader), for personal choice or returning the phone under warranty.
You can unlock the bootloader when not rooted, in fact you don't do it with the phone running normally anyway so root or not rooted, it does not matter in that sense.
You don't need to unlock the bootloader to root, if you are willing to re-set up your phone again. What you need to do is downgrade to 4.2, which is rootable, root, install recovery and flash the 681 pre-rooted zip, and use flashtool to flash the associated ftf file to get rooted on 681.
Follow the instructions in Lord Manhattan's thread that you linked to,in order to downgrade and install a recovery, then visit the following link to get the zip & ftf to re-up to 4.4 (681). You most likely will lose cellular connectivity whilst you are downgraded (there is a way around this, but as you are only going down to 4.2 to get a recovery, maintaining your IMEI for that short period of time is just a waste of effort), but it will return when you are back on 681 (4.4).

- Downgrade to 532
- Root it using Bin4ry's tool
- Backup the TA partition
- Unlock bootloader
- Either update to 681 again and take it from there or flash a kernel with recovery/TWRP and flash a pre-rooted 681. It's easy to root 681, so whatever floats your boat.
Don't mean to hijack this topic but I don't want to open another thread,
if I back up the TA partition, unlock bootloader, root the phone, then relock bootloader, then restore TA partition to bring back the xreality,
I am not going to install custom recovery and Roms.
Thanks for the Informations. I will give it a try the next days and report you if it worked.

Technically it'll work, but i have never done it before. Everything should go smoothly until you're going to re-lock the bootloader. You can't re-lock it on a custom kernel, and you'll be on a custom kernel once you flash Jackie's kernel with recovery, so you'll have to flash a complete stock kernel, then restore the TA partition with the TA Backup Tool, which will also automatically re-lock the bootloader. You should in theory end up with a complete stock ROM with root. That's on paper.
Worst case scenario? If you re-lock the bootloader while you're on a custom kernel, it'll explode it won't power on at all, and all you'll get is a blinking red LED and death. To fix this, just unlock the bootloader in Flashtool again and you're back to start again. It's not dangerous, but it's nerve wrecking to see it there, just blinking without any sign of life. I almost crapped my pants the first time i experienced it, and had no clue what was happening or what to do.

Thanks for the reply, I think I will ditch rooting from this phone, too much troubles, I don't understand why Sony put the DRM key in a trim partition, perhaps they don't want us to root the phone after all.
I did it guys. It worked!
My steps:
- Downgraded to 4.2.2 with Flashtool (.532)
- Rooted with Bin4ry's tool
- Installed CWM and TWRP Dual Recovery for Xperia Z locked Bootloader by krabappe12548
- Flashed to 4.4.2[rooted] (http://forum.xda-developers.com/showthread.php?t=2687848)
Now I have the newest version with Root Access. Everything works great

Yep, that will work well on a locked BL
If you are only downgrading to flash the current rooted firmware, you don't even need to root 532, as [nut]'s dual recovery can be installed by the same method that bin4ry's root is delivered, just install the recovery, flash the zip, flash the ftf and away you go
Hi,
As we all know unless we downgrade and stuff, or install custom recoveries (which require some hackeries) we can't root the latest firmware.
I came across this method: http://whiteboard.ping.se/Android/Rooting
It uses the original boot.img and edits it then using fastboot it flashes it with the su binaries and security turned off.
Would this work on our Xperia?
Thanks
Probably, but you'd need to unlock your bootloader...
That kind of defeats the purpose. I'm trying to not do that
I want to be able to install OTA updates and support.
You can alway relock back once rooted. By that, you can OTA update safely and keep rooting

Ok so if I follow that guide to get root, unlock bootloader, flash the new boot, and relock bootloader, I will be able to install OTA?
Won't that brick my device since I have a modified boot.img?
In order to relock the bootloader you must firdt change back to a stock kernel, otherwise you will brick the phone, wich luckily is recoverable...
Even if yo relock on custom kernel, you will also can enter in fastboot mode to flash stock one

Hi first post. Have just got a z2 from Vodafone which has a locked boot loader now I know this stops me installing custom roms and kernel but will I be able to install stock roms. Mine has come with loads of bundled Vodafone apps and bloatware so want to be able to install stock UK rom. When there available as the battery performance seems to be badly affected.? Thanks
Yes there should be no reason why you can't use flashtool to debrand with an official signed stock Rom.

With HTCs there was a CID number which blocked official RUUs. Are Sonys like that at all? It stopped my friend upgrading to jellybean with the official RUU for ages.

Any stock based ROMs can be flashed on devices with locked bootloaders... This includes official Sony firmware, such as that from other regions (you'd probably want a generic version to avoid bloatware), and developer ROMs that are based on stock. Familiarise yourself with the latest flashtool as this will be your go to software for flashing.

Can someone explain exactly what we can/can't do with a locked bootloader?
Mine is locked, and not unlockable. Can I still flash a non Vodafone/generic Rom? Can it be fully rooted? Can I install different ROMs?
I like this phone a lot, but have until the weekend to decide whether to return it or not. If I can still root and remove all the unwanted apps/bloatware, I'll keep it
Sent from my D6503 using Tapatalk
You can currently root the device, install the (one and only) current custom ROM, remove all bloatware and such just as you would any other phone
BUT
In order to do this the current method involves unlocking the bootloader first before obtaining root access which will wipe the TA partition, thus losing your DRM keys.
You need the DRM keys in order to restore your phone completely back to stock in order to get full warranty...
So until a root exploit is found which doesn't involve unlocking the bootloader first you can't uninstall apps without worrying about warranty - however you should be able to disable them from the app settings menu
Hope this helps explain things better for you

I'm in the same position mine is from vodafone uk, and has a locked bootloader. When a generic stock rom is out can I flash it as normal, which will then remove just the network bloatware?
Thanks
Thank you everyone who took Time to reply does anyone know how long it will likely be before a UK stock rom will be available and where would I likely find it. Thanks once again we

At this moment in time there is no known root exploit so without boot loader unlock all you will be able to do is flash official Sony signed Roms. They can be for any region and any carrier. You won't be able to root or install custom rims.
Once a root exploit is found for any official Rom you will always be able to flash that Rom and gain root which will allow you to install some custom roms that are based on stock and use the stock kernel. You will never be able to run fully custom Rom images like cyanogen as they use custom kernel's which require an unlocked boot loader.

The other day, I set about installing Cyanogenmod 11 on my Xperia Z2 D5603. I was already rooted on the stock rom 4.4.4 Kitkat 23.0.1.A.0.167. I used flashtool to downgrade to 4.4.2 17.1.2.A.0.314, rerooted it, and installed dualrecovery from this link: http://forum.xda-developers.com/showthread.php?t=2785598
But upon choosing reboot after flashing the custom ROM via TWRP, the phone went dark, and wouldn't turn on. The only response I got was a quick vibration every second or two if I hold down the power button. I could not access recovery either.
I was able to revive it by using flashtool to reflash 4.4.2 17.1.2.A.0.314. I tried the same procedure with AOKP ROM, which had the same result. After trying many different things, I realized that factory reset, or wiping 'system' under advanced wipe would cause this to happen. Flashing without factory reset either returns an error, or finishes, but doesn't actually flash the ROM (stock ROM boots)
How to I flash a ROM without this happening? Any help is appreciated.
Have you unlocked your bootloader? It doesn't sound like it.
These roms require another kernel and you need to unlock your bootloader to install it.

I thought that the fact that it was successfully rooted meant that the bootloader was unlocked. Is this not the case?

Hmm no.
Root ! = unlocked bootloader.
Go to the sony website ( http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader) to get instructions to unlock your bootloader.
But with your first assumption in mind, I suggest you read up about it first. Understand the risks and limitations.
