Part 1, 2, 3 & 4: Downgrade, Root, backup TA and unlock the bootloader
== Part 1: Downgrading the Xperia Z1 ==
To be able to root your Xperia Z1 when it has Jellybean 4.3fw or later you need to downgrade it first to be able to use a rooting toolkit, you can succesfully downgrade by downloading this ftf:
- Torrent:
14.1.G.1.534 torrent
- XDA DevDB:
14.1.G.1.534 downgrade FTF
All you need to do to downgrade to a working 14.1.G.1.534 is flashing this ftf in Flashtool. If you don'tknow how to flash an ftf move to the part about FlashTool in this guide
== Part 2: Rooting the Xperia Z1 ==
It seems rooting at the moment will work with a tool called 360rot, you can download it here:
360 root homepage. this tool sadly is in chinese language, I'll try to find out which rooting method it uses ot create an English exploit.
You can also use vroot, I'll discuss this one too
VRoot guide:
- You need to download vroot here:
vroot homepage
- Install vroot, I just clicked next, next, next until it finished installation
I don't understand Chinese, but I rooted my phone
- Open up vroot and connect your Xperia Z1, you need to get something like this:
- Click the green button to start rooting
- When it finished you're phone will restart and you'll get this:
_ Voila, your phone is now rooted
For now this is the guide I made, thanks to
@yeeson for helping me with translating the chinese and giving me screenshots for root 360
- Download and open 360 root
- You'll get a prompt about needing to close the following conflicting service before continuing: adb.exe
- turn on usb-debugging in settings => developer options, and connect your phone
- Open 360 Root again, at this time the upper left corner shows a red font but it isn't to root:
- Click the green button in the bottom right corner, this button is to start rooting your device:
- Progress bar will advance automatically, it can restart a few times, just let it do it's magic!
- When it finished, on top there will be a message: Congratulations, rooting was succesfull:
- To get Root permissions, click the green button in the bottom right corner again now.
- Then the top left corner displays a blue font, this means you are rooted:
== Part 2: Backup TA ==
To backup your TA partition you can use this wonderfull tool created by
@DevShaft
You can find it here:
[Tool] Backup TA v9.7 for Windows
== Part 3: Unlock your bootloader ==
Unlocking your bootloader means you'll be ablet to flash custom kernels and more roms, like CM, AOKP, PAC and all other source based roms. What you need is a pc with adb acces.
You can download the adb files:
- Windows:
Will add these later
- MAC:
Will add these later
WARNINGS:
This procedure will wipe the /data partition of your phone, so you will loose all your stored data, settings. SDCARD will BE WIPED!!!
For Xperia™ devices released 2013 or later (for example Xperia™ Z and Xperia™ Z1), the SD card of your device will be formatted and you will lose all content (for example photos, music, videos) when you unlock the boot loader.
- DRM keys WILL be lost during this process
Unlocking the bootloader isn't a difficult process, just follow the steps:
