Follow exactly what i mentioned if you want to root sucessfully on locked bootloader, i was tried and its work perfectly.
First you have to download the files:
download flashtool here > https://unrestrict.li/flashtool
1. You have to downgrade the firmware to .532 witch is able to support root so download file either direct or torrent here > http://forum.xda-developers.com/devdb/project/dl/?id=3442 and download Official firmware 14.3.A.0.757.FTF from here > http://forum.xda-developers.com/showthread.php?t=2453921 which is need to flash certain files from there, which is called stripped.FTF
if the C6833_14.1.B.1.532_NUT.ftf showed as .zip , simply you change .zip to .ftf and flash via flashtool.
2. Next download root file from binary here > http://forum.xda-developers.com/showthread.php?t=1886460
After download, you have to run.bat then have option there, choose 0 < it's root for ZUltra (you must turn on usb debugging on XZU) you will sucessfully rooted XZU
3. Next you have to install XZUrecovery, so download here > http://nut.xperia-files.com/ ( download files name ZU-lockeddualrecovery2.7.123-BETA.installer.zip (9.37MB) and ZU-lockeddualrecovery2.7.123-BETA.flashable.zip (7.63MB) )
Use installer.zip to push recovery on XZU While flashable.zip is flash together with custom ROM.
If you want to enter recovery > turn off XZU wait for few second and turn on > when you feel viberate > hold volume down button until enter to recovery
3. Next you have to update firmware from .532 back to 757 > you can choose either custom from monX here > http://forum.xda-developers.com/showthread.php?t=2606414 or http://forum.xda-developers.com/showthread.php?t=2712899 (download flashable.zip)
4.Next enter to recovery and make flash the flasable.zip and ZU-lockeddualrecovery2.7.123-BETA.flashable.zip and don't reboot to system, make power off XZU
Then go to flashtool flash the Official 14.3.A.0.757.FTF(Only exclude system.sin) and untick on wipe app, cache and data.
Done, you have rooted XZU with recovery.
I am sorry for the poor english, i try the best to help . If you still have trouble to root, willing to P.M me.

xperia ultra 6833 root
just done guys.All works fine on my new xperia z ultra 6833.
please read carefully tutorial and follow each step and Im sure You get rooted your phone and dual recovery as well.
good luck and Big Thanks

ROOT TO ROM IN X10 Mini PRO (from stock ROM or custom ROM)

ROOT TO ROM IN X10 Mini PRO (from stock ROM or custom ROM)
(thanks to xda developers nobodyAtall, Spyderex, Emperor.dk and many)
updating my earlier post. The complications in installing recovery completely removed. Now it is easy as charm.
I had myself miniCM pro v21 in stock kernal in my x10 mini pro. So this post intends to do on
1. flashing back to custom sony rom
2. rooting (with busy box installing)
3. installing recovery
4. unlocking bootloader
5. flashing custom kernel
6. flashing cutom ROM and google apps
before that : there are many other steps and methods for this but many of them did not work for me. I am describing here what worked for me.
Before starting save all your needed apps using app saver or with my backup root / titanium backup (after root). Back up your account with google account or export your contacts as .vcf to sd card for later import.
You should have through out internet connection and sometimes you would have to switch off the Antivirus to get it done properly. Also allow adb.exe to connect to net through firewall when needed.
1. FLASHING TO CUSTOM ROM WITH SONY ERICSSON PC COMPANION ( if you are having a custom ROM: other wise proceed to next step of rooting)
1. download and install pc companion from here http://www.sonyericsson.com/cws/sup...ject/pccompanion/xperiax10minipro?cc=in&lc=en if you are not already having it. Then make it recognize the phone.
2. Select support and update. It may tell having the latest update but go for repair.
3. Follow the commands. This may take a while
4. correctly follow the command to connect the phone in flash mode (switched off and back switch pressed)
later you have your old blue sony rom back.
1. ROOTING
1. download superoneclik.exe from here. http://www.mediafire.com/file/x1l6n7owj7uldbl/SuperOneClick.zip The problem is that many versions do not help and this version did it for me. Unzip and run the .exe
2. Plug the phone and leave it as such (do not charg/ connect or anything)
3. click root and follow the commands when prompted (like want to test?)
4. done (donate if you feel so)
5. Check for the superuser app in menu if it have been rooted.
Then go to market and install
* busybox
* root explorer (just to be on safer side)
3. RECOVERY
found out the easy way. Thanks to devrruti and rect2049 in xda
1. Download this clockworkmod installer from here https://github.com/downloads/react2409/X10-Mini-Pro-Utilities/CWMInstaller-Windows-v4-dl.zip
2. switch on the phone and connect the phone (ensure debugging mode on)
3. unzip the downloaded zip file and run the install.bat file. Follow the instructions
4. now disconnect when finished, switch off phone
5. switch on and when sony logo comes start multiple pressing and releasing the back switch to enter recovery mode
so there is cwm recovery
4. UNLOCKING BOOTLOADER
download the flashtool from (0.5.3 -I used) here. http://androxyde.github.com/Flashtool/
1. before advancing further download the required ROM (for me miniCM7 from http://minicm.googlecode.com/files/MiniCM7-2.1.8-mimmi.zip )and google apps from http://cmw.22aaf3.com/gapps/gapps-gb-20110613-signed.zip and copy both to the root of sdcard
2. open the install location of flashtool and install the ggsetup-2.2.0.11.exe file inside and install Gordon’s Gate found in /drivers folder
3. then restart the computer, open the task manager and kill any process named adb.exe
4. donot open flashtool after this till needed.
5. Download the s1tool to confirm the unlock certificate of phone from http://db.tt/OrOQO33 and unlocking tools from here http://db.tt/0zUMR5S4
6. Unzip the s1 tool to the designated folder and run the s1.exe. Switch off the phone. Select the Do Job button and wait.
7. Connect the phone in flash mode (switched off and back button pressed)
8. proceed further only if the screen shows semc simlock certificate
9. unplug the phone, switch it phone, connect to the computer
10. run msm7227_semc.cmd in the directory you unzipped the unlocking files to and press any key to start the unlocking process.
11. If everything goes correctly the log will show press any key at the end.
5. CUSTOM KERNEL AND ROM
download the require kernel.ftf from auther’s site (for me the kernel suiting my ROM was nAa kernal from http://minicm.googlecode.com/files/U20_nAa-10_2.6.29.6-nAa-10.ftf
1. copy this to the /firmware folder in flashtool install folder
2. run the flashtool and select flash, then flashmode
3. select the desired kernel
4. switch off the phone and connect in flash mode when pop up requests
5. disconnect phone when the tool says so
6. switch on the phone and enter the recovery mode when kernel logo comes by repeatedly pressing and releasing the back switch
7. in the recovery mode, do a backup from backup and restore option (up and down by volume keys and select by middle switch)
8. do a factory wipe data
9. then flash the ROM zip by selecting the option install zip from sdcard option followed by gapps zip flashing
10. finish this and take reboot (long)
Enjoy the new experience

A guide that can be stickied for newbies. i like this.
You can even modify the thread by giving elaborate colors and headlines and make it attractive. (if you are interested in doing that so)
Appreciate your work bro!
Thanks!
Tim

Like it.. But the rooting part is gonna feel complex for newbies... There are flash file which root and install CWM recovery automatically without any complication...

unnecessary rooting and recovery installs
I appreciate what you are trying to do as SpyderX's thread can be daunting. I think it would be easier to keep people using one tool as you go around the houses a bit.
Perhaps a simpler route from stock using S1 tool and flashtool. This is just an overview as I've copied and pasted it from my blog and would need expanding with links and sufficient detail:
Backup part 1 - use apps such as SMS Backup +, Bookmark sort and backup, APN backup and restore
Check that your bootloader can be safely unlocked with S1 tool (download from here: http://forum.xda-developers.com/showpost.php?p=19624790&postcount=2)
Turn on USB debugging on the phone (in settings in the applications section)
Use flashtool to root the phone (download from the homepage http://androxyde.github.com/Flashtool/)
Backup part 2 - use a root backup app (Titanium backup or MyBackup Root)
Use flashtool to unlock the bootloader
Flash the kernel (e.g. nAa kernel) in flashtool
Boot into CWM Recovery (assuming and flash customised firmware (e.g. MiniCM7)

The drop box links in bootloader unlocking section are not working. Can you please post new links?

Now it can be done with the new version of stool and flashtool. Anyway I will update everything as soon as I get time.

I made exactly the same thread quite ago, I was really motivated and stuff but mods just moved it and got it forgotten in the general section. It even had colors, headlines, sections, collaborators, and stuff, sorry to disappointing you but with staff like this it is impossible to help newbies.. I even explained why post it on the developers section: Strictly, it should have been posted on General, yes, but the guide is directed to new members. Most of them probably doesn't check nor even know there is that section. It got moved anyways without any warning or a single word from the one who did it..
Anyways, good luck.

[guide] how ro revert from kitkat on xperia ray

hi, a quick guide how to revert from kitkat on xperia ray, should be about the same for most xperia 2011 devices.
if you managed to get to kitkat you will manage to understand this quick guide
pre requirements
1) flashtool
2) original full ics tft file of .587
3) eroot
3) cm10.zip (this what i used to revert to)
1) go to fastboot mode
2) in flashtool select flashmode, select that tft file, and be sure to select no final verification!!!
* you can finish here if you want stock rom
3) let ics load, then enable:
a) develop option->usb debugging
b) xperia-> usb method->msc
c) security-> allow from unknown sources
4) run eroot (one click method) to root your device
5) install x-parts from google play and install cwm recovery
* you can finish here if you want stock rom+root+recovery
6) reboot to fastboot and instal boot.img from the custom rom!!!
7) reboot to recovery and install zip
8) profit...

It is not necessary to flash stock ftf file. Usually when I want to downgrade from cm11, I just flash the respective kernel and do the required wipes (system, data, cache and dalvik cache) and then flash the rom. This method certainly works for me and much easier than always flashing stock ftf.

5) install x-parts from google play and install cwm recovery
those steps are really useless if u switch to a custom rom, bcuz
for a) b) c) u dont need this to enter fastboot. only usb debugging may should be needed for flashtool. but i use flashtool like this: prepare all files till it says ''connect device'' then i connect (powered off) device to flashtool AT LEAST. it works on stock ics without ticked usb debugging -for me-
4) & 5) really useless mostly any custom rom comes prerooted. just a waste of time but maybe u add it below ''*finish here if u want stock.ics'' then u can write it for those who want CWM & root on STOCK.ics
anyway thx for ur effort in making this, im sure it helps many , i just also wanna help so dont take this as a complainment
peace

i wrote this after trying to downgrade and failed with other methods.
flash rom from recovery needed older kernel
flashed kernel but than couldnt get to recovery (might flashed wrong kernel though) was stuck on bootloop.
so i wrote this as a fool proof method, would work for many other cases if you have software problems.

Nice guide yes you may add "*finish here if you want rooted stock ICS & cwm" between 5 & 6.

Upgrade and root 5.1.1 Lollipop 14.6.A.0.368 locked or unlocked bootloader

** DISCLAIMER: I AM NOT A DEVELOPER. I DO THIS AS A HOBBY AND SHARE MY FINDINGS IN CASE SOMEONE ELSE FINDS THEM USEFUL. **
** THIS WORKED ON MY DEVICE BUT IT MAY NOT WORK ON YOURS. APPLY AT YOUR OWN RISK **
This post shows you how to upgrade your system to lollipop 5.1.1 and optionally have root privileges. This is tested on C6833 model. For other models see the troubleshooting section near the end of the post.
Requirements:
Flashtool 0.9.18.6. or 0.9.19.6 or higher Important: Do not use Flashtool 0.9.19.0.
If you want to root the phone: Rooted XZU on Android version 5.0.2 or Kitkat with custom recovery installed.
This works on locked or unlocked bootloaders and any customization.
Download link for upgrade only:
C6833_14.6.A.0.368_1275-8026_R2D.ftf (unmodified Customized DE):
https://mega.nz/#!khF1nILD!C5D70e-BjCKVBCuOurjFOLcIMZDcldYVeIDnFiR-PGM
Download link for upgrade and root:
5.1.1-system.zip:
https://mega.nz/#!YoFgCSjA!Zh8t_4jeXcAEWhOYePA40uQLI7vw4-CnxohjBdMbpz0
C6833_14.6.A.0.368_No_System.ftf
https://mega.nz/#!l4dllSTT!R393EG4W3CwOZp1OLOzfUzpHF0IlvsmfW04BrGOggXc
Instructions for upgrading without root:
1- Back up your internal SDCARD and your apps.
2- Download C6833_14.6.A.0.368_1275-8026_R2D.ftf
3- Open Flashtool and click on the flash icon. Choose flash mode.
4- Navigate to where you saved C6833_14.6.A.0.368_1275-8026_R2D.ftf and flash this ftf with your phone in flash mode. I recommend wiping apps and cache and data (Note that wiping data will erase your internal SDcard too). To put your phone in flash mode, hold the volume down button when it is off and connect with the USB cable to the PC.
5- Reboot.
Instructions for upgrading with root:
0- If your existing system is rooted using Kingroot read the troubleshooting section below before continuing.
1- Back up your internal SDCARD and your apps.
2- Download C6833_14.6.A.0.368_No_System.ftf and 5.1.1_system.zip.
3- Copy 5.1.1-system.zip to your phone's internal SDcard.
4- Reboot to recovery and install 5.1.1-system.zip.
5- If you are coming from Kitkat just Turn the phone off. If you are coming from 5.0.2, reboot the phone and let it work through the boot animation which will take a while. Then it will show force closing messages and possibly reboots itself. At this point turn it off by holding down the power and volume-up keys for a few seconds. The phone will vibrate 3 times and turns off.
6- Open Flashtool and click on the flash icon. Choose flash mode.
7- Navigate to where you saved C6833_14.6.A.0.368_No_System.ftf and flash this ftf with your phone in flash mode. I recommend wiping apps and cache and data (Note that wiping data will erase your internal SDcard too). To put your phone in flash mode, hold the volume down button when it is off and connect with the USB cable to the PC.
8- Reboot.
Troubleshooting, etc.
This procedure works only if you follow every step carefully. When you are done you can easily test your root status in a terminal emulator or via adb. Please see the attached image.
If you have used Kingroot to root your existing system flashing this ROM may not work and it may leave your system with a partially updated file system that may be broken. The reason is that Kingroot (which in my opinion is malware) makes some of your system files immutable which means they cannot be removed during a software upgrade. To proceed, you should either find a way to replace this horrendous piece of code with SuperSU or downgrade to Kitkat and root with XZDualRecovery before trying this guide. Read the second part of http://forum.xda-developers.com/showpost.php?p=62936808&postcount=22.
If during the procedure for root the flashing of the ftf in step 7 fails, repeat step 7 with C6833_14.6.A.0.368_1275-8026_R2D.ftf or any other 14.6.A.0.368 ftf but exclude the system partition in the flashtool dialog window. If you don't exclude the system partition you will not get root.
If you have root after the procedure but something else doesn't work, try a factory reset.
Note that flashtool 0.9.19.0 was specifically released to support the new sin format on new devices and some of its features don't work with older devices. So to avoid taking any chances I used version 18.
I don't know if this works for C6802 or C6806. Some users reported success on 6806, like this one and this. For that model you follow this guide and use the zip file posted here. The only difference is that instead of flashing the ftf posted here in the next step, use the stock 14.6.A.0.368 ftf for your phone and exclude system.

Will this C6833 FTF work on a C6806 USA phone?, because I can't find a C6806 FTF anywhere...

Can this system zip be used with other customized versions of c6833 ftf.

You probably didn't exclude the system partition in this step:
7- Navigate to where you saved C6833_Customized+DE_14.6.A.0.368.ftf.*Exclude system partition*and flash this ftf.

Out of curiosity, what is wrong with the latest flashtool?

I was able to flash android 5.1.1 but could not get root and I did every step as posted and I did exclude system partition. and without root could not install dual recovery there for could not flash SuperSU

I am sorry for my noobie question...but what is customised DE?
ALso if i run this, I am still at locked bootloader...will i lose the partition that enable me to have all Sony's special goodies (i didn't mean the bloatware of course)?
Also i am running stock 5.1.1 already after OTA but interested to have root...shall i go with the 2nd steps with root?

Customized DE just means it is the German version of the ROM. I used that because I bought the phone in Germany. But the menus and keyboard and everything is in English so you would not even notice the difference.
This method will not touch your bootloader status so if you are locked you remain locked.
If you are already on 5.1.1 through OTA this will not work for you. You need to start from rooted 5.0.2 with recovery installed.

I think you can still do it straight from kitkat but if you are following the instructions with root in step 5 instead of rebooting just turn the phone off.
Let me know if that works.

so my ZU used to be rooted with Lollipop 5.0.2, but i removed Kinguser/chinese root app and no longer have root access. I've also previously installed recovery but don't know if it will still work ? i forgot how to boot into recovery to see if it even works.. any helpers?

Power on the phone and when u see the led notification start pressing either the Volume UP or Volume Down key a couple of times to make your phone boot into recovery mode

If your custom rom hasn't done ctazy stuff to your phone, like making parts of the OS read-only (which is for example what kingroot does), then this method should work fine with pretty much any custom rom that has a recovery.

Thanks for answer

@ najoor , Hi, thanks for these, I have used the last two on my C6802 without a hitch. Are you planning on doing one for 14.6.A.1.236? Thanks again.

I am not even sure that 14.6.A.1236 actually gives us over the previous release, can anyone say? thanks.

"Flash" means installing something to the internal memory.
You need to go back to a "rootable" version and after having your terminal rooted you can flash the latest rooted ROM.
Following the instructions on this thread https://forum.xda-developers.com/xp...lipopprerooted231a128z2-tabletsgp511-t3100821 I suggest you:
Flash the Lollipop 23.1.A.1.28 firmware with Flashtool;
Unlock the bootloader (not sure it is strictly needed but better avoid potential issues) with Flashtool (use the Sony website to get the unlock code as the automatic retrieval of Flashtool did not work for me);
Root using the script mentioned in the thread;
Flash the custom recovery;
Flash the rooted 6.0.1 ROM.

You cant make the root with the flashtool! Copy the SuperSu (download newest zip) on your tablet (anywhere) and proceed with this: "TabZ2-lockeddualrecovery2.8.21-RELEASE.installer" you already downloaded from the tutorial. when you launch the "install.bat", the tablet will be rooted and twrp installed it auto-boot into twrp and now you can isntall your copied supersu zip then you can proceed with the tutorial
Got it fixed. In my first CWM Backup from the Dualrecovery Package (installer) was a working boot.img All fine now!
