I would love to achieve root without unlocking the BL. Like it is described in this post for the Z1.
The idea would be to flash the FTF for the (stock) JB kernel with Flashtool, apply Easyroot and then flash back the original kernel. At least on the Z1 it seems to work.
I would be willing to try, I just don't know how to get the FTF with the two kernels. Hopefully this shouldn't delete any data either and the root might stick with any future KitKat OTA updates. Does anyone know how to get a copy of the FTF for the D2303 JB and 18.3.1.C.0.21 kernels?

To get FTF for 2303 JB version, please look at the forum, maybe someone has posting FTF files for 4.3 android version.
For 18.3.1.C.0.21 kernel, you can obtain that from FTF 18.3.1.C.0.21, but only flash kernel. Don't wipe data and exlude anything except Kernel in flashtool while flashing.
Maybe you should try XperiFirm for download FTF files.

Ok, thanks. But all JB links I've found are dead. Still is it actually possible with Flashtool to just flash the kernel(s) from the whole ROM without wiping anything? That would be great.
My issue right now is that I can't find any active link to the JB ROM. Also I nearly finished my monthly Internet traffic quota already. And I don't have a Windows PC either (I use OSX). So if anyone with the ROMs and the right skills could make the kernel only FTFs I would really appreciate it.

Actually i have found one 4.3 FTF firmware. It's for D2303 and i have flashed only jb kernel on 4.4.2 but it's not working. After Sony logo, phone only switches on/off so you can't get to bootanimation even. If you have any idea tell me im going to test it. What we need is patched 4.4.2 kernel which we are going to push su file and then flash our original kernel.
Well my model is D2306, and I did the following:
1 - Flash JB ftf, root with towelroot and install SuperSU from playstore (dont update binary)
2- Update through OTA (Update Center) to KK 4.4.2, and then to 4.4.4.
3- Through flashtool, apply root via towelroot again, after reboot, install SuperSU to /system.
And now I'm rooted with locked BL. Try yourself.

Yea, that's working for D2303 too, but is little boring. So everytime when you going to brick your phone while changing build.prop for example or something like that you have to repeat that process and with this idea (just changing the kernles) could be great because it takes less time and it's easier.

So how does it work? After downgrading to 4.3 it gets two OTAs? I think the trick updating with OTAs works because the OTAs must just do an incremental install. Still i can't afford to do it every time, due to my network cap restriction (I know. It feels like living in Neanderthal).

Hi Friends,
I wanted to have my Xperia J with ICS 11.0.A.7.5 firmware to be backed up. So following some post here on this forum stating that first repair phone using PCC and then go to db\13740270\blob_fs and copy 3 files with name "File....." and then convert the file to ftf using Flashtool.
So I first repair it using PCC. It succesfully repaired but after repairing, I found that now it is not ICS 11.0.A.7.5 but its JB11.2.A.0.31.
Also instead of 3 files with name starting with "File..." in db\13740270\blob_fs folder, there are 4 files starting with that name.
Can someone please guide me out of these 4 files, which files are to be selected in Flashtool for creating .ftf file to keep the backup of 11.2.A.0.31 firmware?
Also we know that there are some bugs in JB 11.2.A.0.31 as well as its hard to root this version. So if I want to go back to ICS 11.0.A.7.5, how can i revert back.
Thanks very much.

Regarding the backup I'm not sure exactly but from what I understand you want to save the .31 firmware for future flashing. If so, if the .31 firmware is unbranded you won't need to save it because there are links to the .31 Central European version ftf file on these forums.
And regarding the getting back part, if you ever wanna go back to ICS you can just flash the ICS .ftf file ( again you can find the links in the threads here) and you're done. BTW, if you wanna update to .31 I would recommend rooting the ICS and then updating OTA so that you can keep your root.

Thanks Sir for your guidance.
I did it this way...
Previously it was ICS unbranded and I rooted it sucessfully. Then I Repaired it with PCC (for getting backup of ICS) but it was repaired with JB .31 and root was lost.
Should I follow this way ?
First Flash ICS 7.5 .ftf file, then root it, then OTA update with JB. I also want to know that :
1. Will instead OTA updating with PCC work?
2.Is there any way to get back ICS by flashing with PCC instead of flash tools?
Thanks

Not a problem man.
To answer your questions :
1- If you update withe Pc companion you will loose your root. Only updating over the air will keep the root. ( after you finish the updating process you simply need to update the superuser app from the playstore).
2- Unfortunately, if you use the repair function Pc Companion will give you the latest version available, there is no way of choosing which Android Version to install, it will choose it for you. So if you want ICS you need to flash the .ftf file with flashtools
Hello,
I tried to find a way to root D2303. I unlocked the boot loader the official way.
On my device is Build 18.3.1.C.0.21 (KitKat 4.4.4).
There are two possible ways: Towelroot and CWM with SuperSU.
It seems KK 4.4.2 is needed for both. So I tried to flash 18.3.C.0.37 (KK 4.4.2) it with Sony's tool Emma.
After boot the device had still Build 18.3.1.C.0.21.
What shall I try next?
Here you have a way to root 4.4.4 -->http://forum.xda-developers.com/xperia-m2/general/d2303-how-to-root-kitkat-4-4-4-t2955337
stay on 18.3.1.C.0.21 it is and for this rom root
Use this flashtool, is the best
You said that Towelroot works fine in 4.4.4? Or did I misunderstand the comment? xD
If I'm right, could you please tell me how could root the phone? Thanks
buddy, Towelroot only for JB ... please read a little

That already know xD. So, the thing you try to appoint is Root from 4.3 and then using OTA Update for 4.4.4 KitKat? Is that? Thanks.
1. you need to make a backup copy of DRM keys (this is the forum)
2. unlock the bootloader
3. and then (after reading a few threads on the root), download the appropriate software,ect..., you can start working on the root of your phone
Good luck
Just wondering if the Lolipop update brings any updates to the baseband radio and bootloader etc?
If so - anyone know if there is a way to upgrade these without OTA or Flashtool upgrade, I'm using Rooted LB and will need to use a pre-rooted FTF

There is no such thing as a pre-rooted FTF
What you need is a flashable zip and there are plenty in the development section
Sorry, pre-rooted created from FTF
either way OP still unanswered.
I'm trying to update to either official LP or AOSP lollipop, but trying to flash a zip with recovery just ends in errors with all the zips I've tried to flash with both clockwork and Phil Whi Touch, some zip files fail because of bad footer, some actually say "installed sucessfully" and then just reboot in to my old 4.4.4 setup.
Is this due to a locked bootloader?
I actually can flash ROMS using Sony Mobile Flasher but I've only found the 4.4.4 stock D6603_23.0.A.2.93_Generic GLOBAL.ftf file and not a LP version.
Any Ideas where to go from here?

wow,
OK, official lollipop does not need an unlocked bootloader but AOSP does.
Also, the official flashtool from Sony (Often called EMMA and downloaded from Sony) DEFINATELY needs an unlocked bootloader, it will not work without one.
Only the unofficial flashtool (From flashtool.net) will work to flash FTF files on both locked and unlocked bootloader.
Please provide the actual setup of your phone and show the outputs of recovery or flashtool once you try to flash
dont even try flashing any custom ROMs, youre going to end up bricking your device.
Wtf?. Please do not spread confusion here. Base your posts on facts.
Talk about scaring the users away from custom ROM's
I meant flashing custom roms (aosp: cm roms) on a locked bootloader lol.. My bad

No problem, good you explained.
How to downgrade from this version?? i commited an error on upgrading it via OTA, and, i lost my root, XZRecovery and all.. i do the search on Z3/general but cant find anything talking about D6643.. only for the other models.. can someone help me!? :/
If you really need to downgrade, Google the rom u want, just flash it, and you're done, its always there in Google
When you have root and recovery you NEVER do an ota update!
What you can try:
Flash rootable firmware as you had before with flashtool, download it via xperifirm. Then root and install recovery. After that install the rom you have been on before ota. When you do this all and never wipe data partition, you maybe keep your files and apps.
When flashing rootable ftf you must uncheck data wipe. Dalvik and cache can be wiped. Once i did this on my z1 and z3 and it worked. Should work for you too because the whole xperia plattform works mostly the same.
