Hey guys i just updated to 290 via pc companion, is it safe to unlock the bootloader? And is it possible to gain root? I just moved to the z1 from the nexus4

You don't need to unlock the bootloader to get root. If you wanna keep it locked and get root:

If you do decide to unlock the bootloader. BACKUP YOUR TA:

Yes, before that you have to Backup your TA. Remember, unlocking bootlader will void your warranty.

If you want cm on your Z1 you need to unlock your bootloader. Backup ta first

How do I do this and do I unlock the bootloader before rooting the device ?? Is unlocking the bootloader risky ??

Root first, backup ta, then unlock the boot.

Okay - is there an all in one guide I can follow from someone? How do I backup the Ta partition and do I have to unlock the bootloader using Android Sdk or is there a different way?

[Q] Xperia Z1 help with unroot, relock bootloader and restore to factory settings

Hey,
I've got a Sony Xperia z1 which I will be selling now and I need to get it to factory settings. Im currently running CM11 and am rooted, unlocked bootloader and have a custom recovery. Are there any guides that will get me back to stock firmware and is it possible to get it back so that no one knows it was ever rooted ?? When I unlocked the bootloader I backed up my TA partition.
Thnx

you can flash the latest official firmware via flashtool(root,recovery gone) than you relock your bootloader and use the TA partition.
good luck

Sorry to bother again but Im a bit of a noob :/ In which order do I proceed then ?? Does flashing the FTF via flashtoolget rid of the custom recovery and root the device ? Then I have to relock the bootloader via flashtool too and then restore the TA partition ???

Flash the FTF, root using newroot, restore your TA, flash the FTF again.
Done

Ohhh and this will regain my warranty correct ??

Well, warranty fraud is not condoned on XDA. I have told you how to relock your bootloader and return your phone to a stock state.
If unlocking your bootloader voided your warranty then its voided no matter what you do after that,

Erhmmm sorry I might be a bit lost ( English isnt my first language...) but I think I get what u are saying... So pls one last question - Is a locked bootloader and stock state any different then when I first got the phone ?

You got your phone with a locked bootloader and stock means it is the firmware that comes from Sony, so yes...

Rooted - now what?

After using the gieroot method, what can we do now?
Am I safe to assume we cannot install custom roms without unlocking BL?
What xposed modules are there for the xperia line?

You can unlock the bootloader!
There's no need to unlock it when using stock kernel but if you want to use a custom kernel, then you have to unlock the bootloader.

then wait for 5.0

Seriously, if you don't know what to do after rooting, then why did you root at all?! :silly:

I don't know. Why do we do anything in this world? Why do you go around forum boards and reply to questions you could care less to answer. Why? Why?
Anyways to update this thread - Since this is my first sony xperia phone, i tried different Gem and Serajr Xposed mods and found them to be a bit buggy. One of the mods even made it so the phone was inoperable from an UI standpoint. I had to go into safe mod and delete them.
I tried to run Rectify without unlocking BL but ran into issues. Dev informed to flash stock boot.img. Then I proceeded to install the CM12 nightlies.. running very well!
Remember to backup that TA!
