Pre requisites:
1. FlashTool http://www.flashtool.net/download.php
2. Working Adb


ETA: 1-2 hours

Step 1. Download 14.1.G.1.534 C6902 IN FTF and flash with Flash Tool (this erases internal storage)

Step 2. Enable USB debugging, enable Unknown sources in settings.
Mod edit -Vroot collects your IMEI for no known reason, use it at your own risk
Use Vroot or root360 to root (both are chinese tools) http://singgihjohary.wordpress.com/2013/10/13/root-xperia-z1-14-1-g-1-534-and-later/

Step 3. Install SuperSU from play store and run it.


Step 4. Install DualRecovery using windows installer (bat file) http://xdaforums.com/showthread.php?t=2261606

Step 5 and 6: http://xdaforums.com/showthread.php?t=2687443
Step 5. Flash 4.4 Zip through TWRP (dont reboot, just power off) http://nut.xperia-files.com/?dlid=QzY5MDJfMTQuMy5BLjAuNjgxLmZsYXNoYWJsZS56aXAudG9ycmVudA==

Step 6. While in power off state, enter flashmode (Volume down as you plug in power cable) and flash FTF stripped via flashtool

Thank you so much for the guide! I never rooted an Xperia before (4 years with samsung so all I know is Odin :p), and this will help me a lot!

@taranfx you can skip the vroot part in your guide, you can install XZDualRecovery on the unrooted .534 rom. Saves a step prior to updating :)

thats a problematic point NUT, i've tried that yestarday... flashed the recovery just fine, restarted into TWRP, then i restarted system and asked him to install supersu.

but when i was back into sony rom it sais i need to download supersu from the playstore, and since flashing .534 ruins the 3g reception i couldn't without wifi around...

luckly you don't actually need root to update to 4.4, you just need TWRP working so you can flash the flashable file.

Thanks will do this when I have time, tired of Google's stupid restrictions on the SD card

Adb?

Hi,

I have just looked at the instructions on http://geeknizer.com/root-upgrade-to-stock-4-4-2-kitkat-on-xperia-z1/

and noticed this - 4.Working Adb

What is this and how do I enable it? I am running Windows 8.1. Do I have to install anything?

I just tried running the bat file for the dual recovery (just to see what would happen - no phone connected) and got this -

'adb' is not recognized as an internal or external command,
operable program or batch file.


Any help will be appreciated!

Regards,

Alan

Hi gregbradley,

Thank-you. Sorry for the noob questions but I want to get this right! (I am currently on .681) so to get a rooted version of 681 I have to -
Flash .534
Root it using vroot or Rot360
Install SuperSU (from market)
Install DualRecovery
Install NUTs rooted .290 (or .136) (or can I go straight to .681?)
Install NUTs rooted .681

Is this correct?

Regards,

Alan

When you flash the superSU you will get root, no need to do it before then

Hi gregbradley,

Sorry for all of the questions! Its just that I do not want to screw anything up! So, in order -

1) Flash either C6903 14.1.G.1.534 Generic UK 1276-0875_R9A or C6903 14.1.G.1.534 Vodafone UK (I'm on Vodafone UK)
2) Install dualrecovery
3) Flash SuperSU (is this done through Flashtool?)
4) Update to NUTs .681

Regards,

Alan

Hi gregbradley,

Thank-you for your help! Have you got a non-torrent version of - C6903_14.3.A.0.681.flashable.zip ? As I am trying to download via the zBigz.com torrent downloader and its saying about 5 hours to complete the download!

Regards,

Alan

Not at the moment, download and install utorrent, that should download it quicker
