I have an Xperia Z Tablet (SGP311) want to update to 4.2.2 but for some reason won't let me OTA. Think maybe its because of unlocked bootloader or CWM. So before I just go ahead and use flashtool to update I want to know ill be able to get root access back. Think DooMLoRD's toolkit v17 I used before will work on this firmware for my model and could it hurt to try? Appreciate any help or advice in pointing me in the right direction.

you can only update by flashtool

I tried that but i dont get it working. When i run the toolkit i get some errors. I tried on 2 diferent laptops.
And i dont get the thing were i flash the 423 kernel on locked bootloader. I couldnt flash it on xperia S so i think i cant flash it on Z now.
The kernel is for XZ only, so it wont work on Xs.
Just Try it, for me it's Always working like a charm.

My apologies if this is obvious to you all but ive been roaming back n forth over all the threads trying to find the best course of action. I am looking to root my device (c6903) to 4.3 rooted. I am currently running 14.1.G.2.257 I understand that this firmware cant be rooted and i need to downgrade to 14.1.G.534.
Q1 do i then wait once rooted for the OTA update or do i then backup my TA and flash a rooted generic 4.3 using flashtool?
Q2 is it better to just update to 4.3 generic unrooted and wait for this firmware to be rooted which i believe is being worked on. I have noted that my device can unlock the bootloader if this helps?
Thank you for any advice im a bit confused on which course to take
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.

Hi guys this is my first post here so be gentle! I'm trying to get cyanogen mod on my Z1.
I have followed the guides on this forum, my appreciation to all involved here great job!
I downgraded to 4.2.2 from 4.3. I then rooted my the phone. I then unlocked the bootloader.
All went ok. I then downloaded C6903_14.2.A.0.290_1276-0875_Generic UK.ftf and flashed it. The phone then wouldn't turn back on.
So I downloaded C6903 14.1.G.1.534 EE UK 1276-2219_R9A (I'm on EE) and flashed that and I got the phone working again.
I then flashed DoomKernal to get CWM. DoomKernal went fine.
Somewhere along the line I think I got confused and thought DoomKernal would give me CWM and I flashed C6903_14.2.A.0.290_1276-0875_Generic UK.ftf again to upgrade back to 4.3.
Same problem...Phone wouldn't turn on so I repeated the EE branded 4.2.2 flash.
Now DoomKernal seems to be taken off. So my questions are as followed:
Do i need DoomKernal to get CWM?
Do i need to be on 4.4 before I install Cyanogen mod or can I do it straight from 4.2.2 with DoomKernal?
If I'm being a total noob I apologize!
Thanks.

Accidently gave you a thank lol
I actually don't know about branded phone, but I can tell you that your step has gone wrong. You will always lose root
if you flash a sock ftf file.
So you are saying you unlocked bootloader on the 534 rom? Your camera is probably dead now, check it if you can boot.
Unlocking bootloader before getting on 4.3 or 4.4 will result in disabling the camera. You did it now anyway, I can't help you. Maybe flash 4.4 now and see if your camera works again.
Flashing cyanogen is not about root but unlock bootloader, people would recommend you to root first becoz you will be able to do TA back up with root
(TA backup is a way to backup drm key, so you can restore it in the future and restore locked bootloader exclusive feature like X reality and better quality camera. Seems you don't know what I'm talking about and already unlocked the bootloader before you even ever heard about TA. Sorry can't help you to save this part, you may continue anyway)
So on 4.4, you may have to unlock the bootloader again since the bootloader itself maybe relocked itself when you flash a sock ftf file. ( doesn't mean you restored DRM key is back)
So maybe unlock it again and start to flash cm.
Personally I wouldnt recommend a newbie in Android to unlock bl so fast since it's too easy to mess up serious things up and it's not so easy for turning back. Well you started messing them up anyway, continue then
Thanks for the reply.
I did do a TA back up before I unlocked the bootloader....If i restore from this will it get the camera working?
I have tried to flash Cyanogen mod but it fails error 7. It thinks my Z1 is a Togari (Z ultra) which it isnt cant find anything on this!
Ok so, i'll try and get on 4.4...
I have a UK Z1 C6903.
Can I flash to C6903 14.3.A.0.681 Global 1277-2880_R5C (this is 4.4 right?)
OR does it have to be a UK one I cant seem to find a uk 4.4?
So after a bit of stress and the phone getting stuck in bootloop I have installed 4.4.2 using .681 commercial.
I hope it will be smooth sailing now to install cyanogen mod
Oh and the camera works again!

happy to hear that u actually did TA backup

after that install doomlord advanced stock kernel v2 i think
Hi guys, up till last week i had an xperia z for nearly 2 years and rooted it on several occasions, however the phone developed a fault and was returned to Sony.
I was sent a new device today (6603) which came with 4.4.4 10.5.1.A.0.292 but i want to put it back to how i had it on 4.2.2 10.3.1.A.2.67, for some reason i just cannot get the phone to root. I have used the procedure that i always used but this time i cannot get it to root. I would downgrade to 10.3.1.A.0.244 via flash tool, no problem. Then i would flash 10.3.A.0.423 kernel only but in settings the phone would still say the 244 build, then use doomlords v18 to root but i cannot get SuperSU installed....
I have tried many methods from the net to no avail. I went into the service menu and its says i can root
Any help will be much appreciated, any more info u guys need i can let u know.
Thanks
c6603

why don't u flash 10.5.1.A.0.292 firmware, i think kitkat 4.4.4 is very good to use and it is very easy to root
lollipop is good too but we can't root it now.
