Hey everyone, I stupidly didn't backup my DRM keys so i cant update my Sony Xperia Z1 via OTA updates so now i'm stuck with custom roms
Anyways the reason i unlocked my bootloader was to get stock android installed but after doing everything i got upto the last stage of installing the zip files aka cm11 nightlies but got a strange error message on install... i got the message saying this isn't a honami device and it was a togari :S i've tried several times and decided to start from the beginning again,
Anyways starting again ive already got the bootloader unlocked successfully, now i want to successfully root but i never know what's the most recent version that can be rooted? also if i do need to downgrade to root how do i get root back from upgrading :/
alo ive tried the few and only few recoveries managers for installing custom roms but they all suck...no offence but ones i've tried seem to be causing no soo much trouble...I just want 1 recovery being Clockworkmod touch that actually works like i remember on my old samsung, asus and nexus devices
and finally if i can get back up to the stage again get stock android installed on this finally! i was tying the official nightlies of Cyanogenmod but either they do work or they dont guess it just might be my really bad experience with sony devices
I hope i can get help on this as im lost now that ive lost my keys and no backup to restore my phone meaning i cant update via pc companion or OTA updates
Simply.
Download stock firmware for you device and flash it via flashtool.

You can still use official Sony tools to update, just relock your bootloader (you do not need a ta backup of your drm keys to do this, just flashtool), flash a stock ftf (as mentioned above), then use pccomapnion to update

As the JB update for Xperia T already came, I inevitably would like to upgrade as well. Problem is, I have unlocked my bootloader, which from what I heard, rendered it impossible to receive OTA updates. I have a bunch of apps (and game save data) that I don't want to lose/re-install. Note: my device is an LT30p, originated from Hong Kong and unlocked.
So what is the best course of action in my case?
1. I thought about relocking bootloader, but will anything be lost during the process? Will I be able to receive updates afterward?
2. Is it true that unlocking bootloader will render it impossible to receive OTA updates?
3. I tried manually refreshing system update, but nothing so far. It might be possible that the update has yet to reach my region, but is it possible that the unlocked bootloader could have something to do with it?
4. Is backing up my apps (using PC companion), then reflashing to JB (with flashtool), and restoring data afterward a viable option?
Rooting my current firmware and backup my app data using apps requiring root permission seems to be the safest route, but that's too much of a hassle.
In any case, I would like to hear your ideas on my situation. Thanks in advance.
You can use Sony's backup and restore app. It resides on the phone itself, and just got safeguarding copy the backup from your internal sdcard to your pc
Did I help? Please press the thanks button

Thanks, I was not aware of the app.
The backup is interchangable with the ones created by PC Companion, I presume?
I really don't know.. Sorry

Download flashtool
Download ftf file of. 157 kitkat for your phone's model
Install flashtool and drivers Google it also if you are using Windows 8 or higher some additional steps are required to install drivers
Switch off your phone
Once done open flash tool click on lightning icon select flashmode
Browse through your pc for downloaded ftf file select it and click on flash button
Now wait and once the dialogue box appears with phone's animation
Connect your phone along with pressing volume down button
Then once dialogue box disappears release volume button and let it do its thing
Then disconnect your phone and turn it on when flashtool says so in logs
Now you have kitkat..!!
I too, thinking of rolling back down to KK
Reason being battery drains faster, intense lagging in some apps, like what's app. Lag in games. Random reboots already more than my time in KK and it'd less than 2 weeks.

Stock LL 5.0.2 | Root |
This works,but before you do it ,back up everything from phone!
Hello i have upgraded my Z3C D5803 from 5.0.2 Slim Rom (twrp and rooted & bootlader unlocked) to 5.1.1 Stock Firmware 23.4.A.0.546 using XPERIFIRM to download and Flashtool to package and flash to the phone.
I have been looking for days but i am unable to find a way to root the stock firmware without having to reflash a custom firmware. I use the ScreenMirroring and Dualshock Support on a daily basis and this is usually taken out of custom roms as Bloatware.
Everything i have tried so far has not worked. Currently it is completely stock, no custom loader, no root (however I do not know if flashing stock rom via Flashtool will relock the bootloader?) Edit: Although from what i have read and understood it is not possible to relock the bootloader (that easily)
I have had many android phones/tablets and rooted/unlocked the majority of them, i just cannot work this one out =[
Thanks for any help
Did u already tried to downgrade , get root and reflashed an prerooted Firmware from here?

I am exactly in the same position. All I want is my COMPLETELY stock 5.1.1 to have root access, and possibly custom recovery. I don't want it pre-debloated (will remove the apps I want remove with Titanium) I don't want Xposed or anything added to it.I don't want to have to flash-downgrade ROM or worse, install a custom ROM, then reupgrade, and all the palaver.
Just like you I have rooted and CWM'd successfully many phones like Xperia X10, Xperia Mini, Galaxy S1, Galaxy S2 and Fairphone and I have always managed to do it in a fairly straightforward way. Just like you I cannot work this one out. I have spent the best part of my free time in the last week searching the web and this website, to no avail. No one and nowhere is offering a simple way to root & CWM the Z3C on stock 5.1.1. It seems even less likely on a D5833 and even less so on a locked bootloader!
Feeling like giving up on this phone.... :crying:

Problem is, atm u cannot root directly 5.1.1. U have to downgrade.
I have lost function of the camera button by going through all that flash-downgrading, custom recovery, reupgrading etc... I don't want to do that and screw up my phone any further, so I'll wait for a safer and more straightforward process to come up...
I have a C6603 that I rooted into a custom KitKat 4.2.2 with the help of xda back in May 2014. I tried flashing Nougat 7.1.1 using Resurrection Remix OS but something went wrong - it didn't seem to get into recovery and became totally locked. I tried all sort of things but the only thing that worked was Sony's own Xperia Companion, which installed Lollipop 5.1.1. (horrible!) Now I have lost root and the bootloader is locked. The service test says it is unlockable. Sony have a website that describes an unlocking process which involves mega downloads on my PC. The instructions don't seem to relate to what I see on the screen, so I could not get anywhere with it.
Is there any way I can get back to where I was with 4.2.2? I still have all the downloads with which I installed it nearly 4 years ago. I did a full Titanium backup before I embarked on this folly. If I could get to 7.1.1, that would be nice - but that has lost me a lot of sleep already!
OK, let me put this another way.
Has anyone flashed an Xperia Z C6603 with Lollipop 5.1.1. using Sony's own Xperia Companion, and then unlocked the bootloader and rooted it? And if so, how did you do it?
Hello everyone
Some months ago I got the Xperia T (Lt30p)
Ive been browing on forums about the posibility of install a stock rom
I know the basic and normal process of install a rom (since I did on old phones), but this time, it seems I ned to upgrade the phone in order to get the recovery and then follow the rest of the process
Is there anyway of make a backup of the original stock rom i actually have? , I know was possible with the recovery, but I cant find the way to install the recovery in my version
Sorry for pening a thread of this old phone, but , I really liked it, but would like to upgrade the android version
Android 4.1.2

Okay, first of all, go to your phone app and enter *#*#7378423#*#*. Then navigate to service info- configuration. If it says "Bootloader unlock allowed: yes" Your bootloader is still locked and you could try to update your phone via an over the air update if available or Sony Companion, or whatever it's called.
If it says "bootloader unlocked: yes" you could try to flash any firmware with flashtool by androxyde. As long as you uncheck the box with wipe data all your data will be kept.
A backup of your files is only possible if you have a custom recovery installed. For that you need root and it's risky if you're new to it.
I don't have any working Xperia T anymore, so I can't give you an advice since it's been such a long time that I flashed it.
If you follow my suggestions above you'll be able to update to Android 4.3 though. In the service menu at the point Software info you'll find your customization version. Write it here and I'll see what the newest version for your phone is.
Cheers

It says
Bootloader unlock allowed: NO
And its already rooted(came rooted when I bought it) I used to do it with some old phones (well, way older), so I know some of the risky stuff
The thing is, I was searching for a recovery to install, but , apparently it only can be done on android 4.3 (or at least is what Ive seen around, I still having the 4.1) , I tought would be the same process to drop the files on the system folders
And the customization number 1266-9267_R21
SO, shall I try to directly update to 4.3 in order to install any other stock roms?

Ok, so I searched for the xperia t, but it looks like there's nothing I can do, as it's not listed anywhere anymore. If you search for android 4.3 ftf xperia t you should find the update.
Rooting Android 4.1 was pretty simple, I can't remember though. Sorry mate.. It's been such a long time since I've used this device

I found the tft for 4.3, but I wanted to wait to see if I could make a back up before I really like how does it look with 4.1, and in case something went wrong, so I will try to update it directly...
Hope nothign goes wrong, since , Xperia Companion doesnt recognize my phone, but an old xperia x8 or an experia e1 are being recognized
Still, thank you bud
