Is it possible to use flashtool to flash OTA

Am a new bee with Sony mobile phone, and want to know: Is it possible to use flashtool to flash OTA files? So I can keep locked and rooted from Ver. 534 to Ver. 257?

No
flashtool flashes FTF files only in flashmode.
But of course you upgrade to .257 using flashtool and stay locked and rooted..thats what flashtool is for

I don't understand, can you flash .257 and keep root?
Doesn't he need to have or get a .534 that's from the right region, root it, then OTA?

You cant flash anything in flashtool and keep root.
He can use flashtool to flash 534 FTF to downgrade using flashtool then update OTA (Via the phone) to update and keep root.

[Q] How to root stock .257 firmware if bootloader is locked?

Hello, sadly I have rooted the Z1 within .534 without unlocking the bootloader and didn't realize that update via PC Companion overwrite the root access. I updated to .257 with PC Companion and then I have a Z1 updated, unrooted and without being able to be downgraded to .534 as I have read in other threads.
Can anyone help me to root the device in this condition? Suggestions?
Thanks

Download a .534 firmware FTF here : http://forum.xda-developers.com/showthread.php?t=2469191
Flash it with Flashtool : http://www.flashtool.net/index.php
Root with Kingo Root
Update to .257 with OTA

You follow the either one of the 3 or 4 guides that are in the general section.
PS, you can always downgrade no matter of whether you are rooted or not.

Unable to update z1 to 4.3

I got a prompt that a new update is available today. I tried to update but was unable to PC companion said i have a modified software. I tried to flash the stock ROM .290 back. But after that my phone did not book. I flashed .534 but my phone is not connecting to mobile network and i cannot update to .290.
I had the boot loader unlocked. But since i have flashed .534 again, not sure if it is locked. Is there any way for me to get my phone to work again ?

Flash the new FW .136 via Flashtool v0.9.13 in Flashmode. Turn off the phone, hold volume down all the time, connect to PC, let windows install drivers, flash the FTF.

Ok, then you want the official update? Nobody know when it will available in your Country but is rolling out, if you do not want to wait you can download it from XDA and flash it via Flashtool, is the same like the official but not branded and no bloatware. BTW if you have problems like you just mentioned probably you should flash it via Flashtool.

I got the official update notification via PC companion. But probably bcoz i had a custom kernel/ unlocked bootloader it din flash it. So I was impatient and flashed the stock 4.3 and boot looped my phone.

There is no better way and I think is something wrong there. Maybe you should relock your bootlader and then update to .136.
Did you try to repair with PC Companion?

BTW, if you relock your bootloader probably you will can update via PC Companion. But somebody reported have problem to Unlock Bootloader again on .136

So finally this is the method that i figured out, that might work (worked for me).
1. Flash .534 via flash tool. (phone will boot up but you will have no network).
2. Root and restore TA backup
3. Install the latest update via sus

Good, just like I mentioned.

<SOLVED>[Q] TA backup with firmware 14.3.A.0.683 (Sony Xperia Z1 C6903)

Hi,
I'm trying to backup the TA on my Xperia Z1 (C6903) running the stock KitKat firmware (14.3.A.0.681). From what I understand though, you need root to backup the partition, but to get root, you need an unlocked boot loader. I've seen a few tools that roots without unlocking the boot loader, but I need to downgrade the firmware to at least Android 4.2.2. Downgrading requires an unlocked boot loader.
Are developers working on a root-and-unlock tool for 14.3.A.0.681? Is there already a tool out there?
Thanks in advanced. Sorry for my arrogance.

You do not need an unlocked bootloader to get root and or to downgrade. Although yes, you would have to downgrade to 4.2 to get root. Just use flashtool to downgrade and pick a software to root

Cool
Just a couple more questions. Any suggested 4.2.2 and 4.4.2 firmwares to flash (if you can, link them here)? To root 4.2.2, do I simply click on the unlock icon shown in link?

I've used vroot 1.7.3 english and everything installed fine. However, when I installed the Root Checker app from Google play it reads "Sorry, this device isn't properly rooted."
Here's what I did / planning, in order:
1) Downloaded C6903 14.3.A.0.681 Global 1277-2880_R5C
2) Downloaded 14.1.G.1.534 downgrade FTF [NUT]
3)Pasted the 2 FTFs in the Firmware Folder under Flashtool
4)Flashed 14.1.G.1.534 downgrade FTF [NUT] using Flashtool from Androxyde (latest version)
5)Installed vroot English (1.7.3)
6)Clicked on the Root button. Phones reboots twice
7)After phone first start I was greeted with an error message from "Kingsapp".
8)Installed Root Checker from Google Play
9a)"Not properly rooted" <-- I'm right here
9b)If "root successful", proceed to flash C6903 14.3.A.0.681 Global 1277-2880_R5C
I did some research and people are pointing everywhere, vroot, bin4ry's rooting method, 360 (can't install).
Did I lose my TA partition? My X-Reality goodies?
What am I doing wrong?

Okay so now you are still on .534 firmware right? Do you have usb debugging on?
And also try rooting with bin4ry if vroot doesn't work for you.
Don't worry, you won't lose x-reality unless you've unlocked your bootloader

"Su upgrade failed. Missing root permission"
Yes, I'm on the .534 firmware. USB Debug turned on.
I'll try bin4ry's root now.
Once I'm through TA backup, I just need to flash 14.3.A.0.681 Global 1277-2880_R5C?

[Q] why do I'm unable to upgrade to kit kat?

Hi,
I have a 4.3 installed on my phone, I woul upgrade to 4.4, but I don' know how to do that.
If I check with pc companion, ittell me that there is no upgrade, and the same by OTA.
I'm wondering if is it possible that I'm still out of upgrade.
How can I upgrade it...?
TIA
Renato

Is your Z1 a UK unbranded one? Uk unbranded seem to be always the last one to get updates. You could back up your phone then perform a repair. Doing repair may wipe your phone so consider before doing it. BTW you have posted in Q&A section. Please move to Q&A Moderators many thanks

If you have root or unlock bootloader on your device you cant upgrade it through SUS or PCC. Lock it back or flash it via flashtool.

This is incorrect.
If you have root you can still update via PCCompanion or SUS, but you will lose root.
If you have an unlocked bootloader then you cannot use official tools such as PCCompanions or SUS, you can only use EMMA (Official tool from Sony for unlocked bootloaders)

ok, I thought I can do it with OTA or pccompanion. I thought it is a "regular" upgrade for Z1. Indeed I need flashtool? I need to root Z1 ?

You will be able to use PCCompanion once the update becomes available for you, they are not all released at the same time, it can roll out over a month or two.
In the meantime, you can flash a FTF using flashtool from flashtool.net and there is no need for root. It is just a repackage of an official download and made avaialable for all.
Find them in the FTF mega collection thread.... Use the search button.
