Hi experts ,
My xperia z2 was on 5.0.2 and rooted with Kingroot , I upgraded to 5.1.1 but root method is too complex for me , i want to downgrade back to 5.0.2 where kingroot is still possible ,.
I have saved my original stock 5.0.2 by compiling the Files from blob_fs folder from PC companion , Shall i flash this ftf file using flashtool directly or do i need to something else ?
Just flash 5.0.2 ftf. And don't forget to wipe user data when downgrading.

downgrade to lollipop 5.0.2 (by flashing a new ftf via flashtool)and root via king root and install recovery via xzrecovery app (after getting root access) and then follow these steps:
1.Download a pre-rooted firmware 5.1.1 (flashable zip)
2.Boot into Recovery (TWRP Recommend)
3.Install - Choose ROM direction - flash the ROM zip and wipe cache\dalvik cache
(don't worry this won't wipe your data)
# I highly recommend you to do a factory reset after flashing because if you didn't the phone will be laggy and battery will drain extremely fast
*And If you have xposed installed don't forget to remove it because it may causes problems
If I Helped, Leave A Thanks ?

Z2 with Bell Canada, locked bootloader.
Seems one of the forced ota updates has un-rooted my phone...
What is the best way to root it again?
Android 5.1.1
Build # 23.4.A.0.546
Cheers.
Same way you did it the first time I guess
Hi there,
With a locked boot-loader , you will have to flash an older root-able firmware ( think .134 ) in Flash tool . Root the phone, sure Towel root works, then flash a prerooted flash-able zip.
Or create a prerooted with PRFCreator.

Had to roll back to D6503_17.1.A.2.55 to get it to root, now I'm just looking for pre-rooted firmware, any that you recommend?
Just download the latest bell ftf file (it will be what your ota version would be), and create a pre-rooted flashable zip using prf creator. Tutorials are here on XDA. They're very easy to follow.
I ended up creating a ROOTED update package from stock FTF
Seems to be all good now

Ok so im by no means new to rooting and roms and the like since ive rooted every phone ive had over the last 5 years but for the life of me i can not seems to figure out these sony devices. So i downloaded and flashed the new 5.1.1 ftf thru flashtool last night and everything is working fine. I have google and searched thru xda about ways to root and i thought the first step would be to install XZdual recovery but i downloaded nuts installer and ran it which seems to have worked but it still does nothing whether trying to manually enter recovery or doing it thru adb. Ok guys what am i doing wrong? Any help would be great!
Must downgrade to 4.4.2, the XZDR will root and install a recovery, then you install a pre rooted package or modified but stock-based 5.1.1 ROM, you won't loose root or recovery; but you wont be able to update via "official" methods like OTA or PC Companion because you have modified the phone's software.
Step # 1 is downgrade to 4.4.2 (314 build number works like a charm)
Damn what a pain but thank you for the reply at least thats a start since there are lots of guides for rooting 4.4.2 lol. Thanks
You don't have to downgrade to kitkat, You can downgrade to lollipop 5.0.2 (by flashing a new ftf via flashtool) and root via king root and install recovery via xzrecovery app (after getting root access) and then follow these steps:
1.Download a pre-rooted firmware 5.1.1 (flashable zip)
2.Boot into Recovery (TWRP Recommend)
3.Install - Choose ROM direction - flash the ROM zip and wipe cache\dalvik cache

If your going to downgrade to an older version of Android, why not go to a version of Android that can be rooted by an app that that doesn't require internet access or all the permissions of kingroot?
Kingroot requires a lot of permissions on your phone to complete something fairly basic.

Hi, I am a newbie here, I have a problem with flashing the rom (zip file) in the recovery that is my phone will crash (restart instead). And I have my phone locked bootloader here is what I have done to my phone
1) using flashtool to downgrade to a rootable rom ( 23.1.A.1.28 )
2) after flashing I use kingroot to root, after that install busybox and last install xzrecovery.
3) after I reboot my phone to twrp recovery and wipe data to perform a rom install (twrp version v2.8.6.0 )
But when I install the rom my phone restart and I stuck and the Sony logo boot screen.
How do I solve this problem.
Thanks

Downgrade firmware to. 314 kit kat and than root and install recovery and finall y try to flash rom.
For locked BL you must flash stock based custom roms.

A bit of background here:
I am trying to get setup for a fresh install of [ROM][LOLLIPOP][LB/UB][5.1.1] eXistenZ Premium | 7.0.0 | FINAL | 16/02.
As per that threads directions:
Fresh installation:
LOCKED & UNLOCKED Bootloaders
Flash latest rootable Sony's rom with flashtool (http://forum.xda-developers.com/show....php?t=2162907)
Root
Install NUT dual recovery (http://forum.xda-developers.com/show....php?t=2261606) or the recovery of your choice.
Reboot in recovery, Wipe Data, Cache and Dalvik/ART Cache.
Flash the rom.
Flash update if available.

So I am struggling getting a "lastest rootable sony" stock ROM working with root. All my tools are working just fine (ADB/Fastboot/Flashtools/PRFCreator) and bootloader is unlocked, I've just been out of this way too long. I can get a stock FTF file flashed but I just can't get root. I think I really just need to know which FTF to grab and which root technique I should be using for that FTF version. I've tried grabbing some older FTF's (KK) but I still haven't had much luck with root. The flashtools root techiques all give me the same "ERROR - Illegal key size or default parameters". With my understanding and past experience this really should be an easy task but it is definitely not being so right now.
Any specific advise I would really appreciate right now.
To be clear right now:
Boot loader is unlocked
Tools are working ADB/fastboot/Flashtools
No custom recovery
No Root
I can flash any FTF no problem
i get root with this method, downgrade to KK, root and recovery (root in KK is easy) then flash via recovery any custom rom, in your case eXistenZ
What version the firmware are you using and what root technique?
I tried a KK version and towelroot app. App reported root was achieved but it wasn't.
Going to try 23.0.1.A.0.167 which should be KK 4.4.4 from http://forum.xda-developers.com/showthread.php?t=2759934
Best root Method for kk 4.4.4?
Shouldn't be too confusing if you done it before. Basically you are going to flash a custom kernel with built in recovery and flash a SuperSU zip to get root before flashing your rom.
1. Download and flash stock Lollipop 5.1.1 FTF (either 232 or 264) with flashtool.
2. Download AndroPlus Kernel for Z2 here.
3. Flash with fastboot.
4. Download SuperSu zip and place onto SD card.
5. Boot into recovery and flash the zip. Reboot without wiping anything.
6. Download your ROM, in your case eXistenZ and place on SD card.
7. Reboot in recovery, Wipe Data, Cache and Dalvik/ART Cache.
8. Flash ROM and update.
9. Reboot and you're done.
