[Q] Clarifying question about 4.3 root.

This is for my curiosity and many other users who I know are wondering the same thing, I've searched for this, but can't really find anything that answers it to my satisfaction.
So I'm running 4.3, with build number .290
I want to root my phone, but I know I need to flash .534 back to my phone. As far as I know, THIS will stop my sim being recognised by the phone. Do I then need to ROOT the phone, and then flash .290 again for the sim to work again.
So which .290 flash will I use? Just the normal FTF file for .290?
Thank you, I'm an active contributor to the forum, but I like to be super sure about what I'm doing before I do it, and I gather many other users do. The reason I'm asking in such detail is because my phone was rooted before, I updated (by mistake) to 4.3 and then flashed back to .290 where it stopped my sim working. Took me a few hours to work out how to fix it, as the pccompanion wasn't working for me!
Thank you!

why don't you unlock your 4.3 rom and flash a recovery to root it ? would be easier

If you want to flash the firmware you have, follow this guide from part B to part C, then you will have a ftf copy of your current firmware.
About the root thing, downgrade to .257 then .534 so you don't have the IMEI and signal issues. Then root and OTA to .257 and then, if you get OTA update to .290 go for it, but some people said that you will only get partial root access.
So you will have to either flash a prerooted firmware or unlock bootloader and turn off Sony's RIC and then root the normal way.
To unlock bootloader, just follow the instructions here but don't forget to backup the TA partition using this guide.

[Q] Updating to 4.3

Hi guys,
I have just rooted my new Sony Xperia Z (Android 4.2.2) and I would like to upgrade to Android 4.3.
I was wondering if there was anyway to get the update without loosing my root access?
I am pretty unexperienced at all this stuff. I've heard that "flashing" the 4.3 firmware keeps the root access?
Thanks,
-Lambo

Just flash a prerooted 4.3 through cwm and your root is preserved, just like that

If your bootloader is locked just update it over the air. If your bootloader is unlocked flash a prerooted Rom via Cwm or twrp.
Just flashing a ftf file via flashtool wI'll make you lose root

Thanks guys for the responses. Does anyone know where I can find a pre-rooted ROM?

There are several in the development section.

[Q] Rooting and dualrecovery

I apologise if this is previously sorted out, but I am pretty new to the xperia lineup(2nd day).
I have a C6902 with build number 14.1.G.1.531(android version 4.2.2)
Can I use bin4ry's tool to root?
And then directly use the XZdualrecovery installer?
At present I do not wish to unlock the bootloader neither upgrade to kitkat, but want to try stock based custom 4.3(flashplayer! Yay!) JB. Will iHackers 3.0 be installed without loosing root and the dual recovery?

bump
Anyone?

I'm not sure about the bin4ry thing but there are many ways u can root on z1 since it's on .531
maybe vroot or king root
yes, then u can install dualrecovery and go for iHackers 3.0, your dualrecovery will be still here after installing
have fun

Help Updating a Rooted z1s

Recently Sony has launched the Kit Kat 4.4.4 on the T-Mobile Xperia Z1s. I have the Original 4.3 Jellybean Rooted. I would like to update but I downloaded the update thru my phone and it gives me the DEODEX menu I think is what it is called. I am a newbie or a beginner in this. I did the root myself reading and following steps. Is there anyone who can help me out because I know the Z1s comes with bootloader locked. I had to rooted not like many other phones with just one click or a few steps and its done. Please don't judge me or tell me What I should Do. I came here because I know you guys are the best and know WAY MORE BEYOND I know. Please Let me know how to update it with out loosing any info or root. I do not run custom roms, I have also always wondered what are those for, what do they do. But I do not modify anything on my phone but just the SuperSU that grants permission to certain apps that need root access.
Thanks.:cyclops:

You can't update it with root on it.
You need to flash stock rom or unroot to install update and then root it again if new firmware is rootable.

[Solved] Xperia T - 4.3 not able to root

Hello
I've been trying to install Cyanogenmod on my Xperia T.
However, I need recovery (CWM) to do so, which requires root acces.
I've been able to unlock bootloader but rooting isn't a succes.
I tried all the root functions in flashtool, and some others but nothing works.
So, is it safe to downgrade my firmware from 4.3 to 4.1.2 with flashtool, root that version, and then install recovery/cyanogen?
Thanks!

Yes it is safe. You can install any custom rom from any stock firmware (unless it states in the description that you need a certain firmware).
Btw: did you try towelroot? I believe it should work on 4.3

Allright, just wanted to be sure!
I've tried towelroot but it kept rebooting, even on 4.1.2.
But I've been able to flash CM on my xperia a couple of minutes ago without problems (apparently it came with its own recovery menu).
Developer tools had a root option and that luckily worked.
Thanks for the help :good:
