[Tip]{All firmwares} Easily root an Xperia ZR with unlocked bootloader

thHello all,
This is a known way to root any android phone with an unlocked bootloader. I tested it on my ZR, it just works fine and is easy & fast to follow !
It works for all firmwares and it's a good way to root the latest stock rom (eg .67 / .244 or even KitKat firmwares).
Note: I'm not responsible if something happens to your device ! Just follow the procedure and all'd be fine !
Quick instructions
Unlock bootloader
Flash any CWM-containing kernel
Boot into recovery and flash su-bin-arm-signed.zip (or this one that worked for me on KitKat)
Revert back to stock kernel
Install SuperSU and update su.bin
Enjoy
Instructions for noobies (yes I didn't forget you !)
Unlock your bootloader.
You may want to backup your TA before. In this case you need an already rooted phone. I personnaly downgraded mine to .310 then rooted it with Doom's toolkit to be able to backup my TA.
Download and copy the following file to your phone: su-bin-arm-signed.zip (or this one for 4.3)
Install the firmware you want to be on when the phone gets rooted
Flash a kernel that contains CWM, for example this one which comes from CM 10.1 FXP234a (you can also try to hotboot it, didn't work for me).
You can flash it with a command line or a soft like FlashTool:
In FlashTool select Flash > Fastboot mode
Connect the phone in fastboot mode : when powered off, connect it to your laptop while pressing Volume + key. You can release the key when the LED turns blue
Select the kernel to flash and run the operation
> Now do not try to boot normally the phone because it won't boot, as the kernel's not compatible with the stock rom.
Boot into recovery:
Power on the phone
When the led turns violet at boot for 3", press Volume +
Now you are in recovery. Use Volume buttons to navigate and Power to confirm.
Select Install zip > Choose zip from sdcard or external sdcard (depending where you put the .zip to flash)
Choose su-bin-arm-signed.zip
Confirm
Go to Advanded > Power off
Flash back the stock kernel corresponding to the firmware installed on the phone (.244 -> .244 kernel). You can for example use Flashtool:
Download the .ftf of the build installed on your phone (no matter the location of the firmware)
Run Flashtool
Do Flash > Flashmode and select the .ftf you downloaded
Uncheck anything on the "Wipe" colon
Check everything on the "Exclude" colon except "KERNEL"
You should now only have kernel.sin and loader.sin on the content colon.
Click on Flash
Connect the phone in flash mode : when powered off, connect it to your laptop while pressing Volume - key. You can release the key when the LED turns green
Reboot the phone, install SuperSU, run it and update the su binary
You can relock the bootloader with Backup TA to recover warranty or Bravia Engine 2 without losing root.

- Stock .244 kernel
- Stock .67 kernel

Backing up with pc companion, downgrading with flashtool, rooting and then wait for OTA update and after that restore the backup with pc companion.

Regarding backup of TA partition, does it have to revert to original firmware or can I back it up even after flashing 4.2.2 with root?

Backing up TA Partition can only be done BEFORE you unlocked bootloader.

Thanks NeoJeo for this awesome rooting method! Flashed the Nordic 4.2.2 ROM on my Xperia ZR and it is working like a charm .
I've backed up my phone's TA partition just in case something goes wrong and I need to re-lock it and give it for servicing .

@ Grim_ripper: Is your bootloader already unlocked ?
@ su1979: You're welcome, glad I helped !

thanks!! I'm testing !
Is it possible to re-lock the BL if I didn't do any TA backup before?

Hello,
No, not possible for the moment. For other devices such as the Xperia Z we can relock the bootloader by flashing a .ftf but without recovering the drm.
The backup and restore tool is the better way to reloock but it needs a backup before you unlock the BL.

I cant acces to the recovery mode even i press vol+ when i see the green light
Did i do something wrong？
The device is working good so far by this rooting method.
I just want the recovery mode back:cyclops:

If "select kernel to flash" says something like
"writing 'boot'...
FAILED (remote: Command not allowed)"
It means your bootloader is not unlocked yet.

oh, I mean after I flashed back the stock kernel.

I am sure the BL is unlocked already as I flashed CM10.1 before.
anyway, Thanks for your advise

Edit: Use PRFCreated method for lollipop 5.0.2->5.1.1
Edit: For windows 8/10, you need to enable test mode for S1Boot fastboot driver install, you can also sign it with Zadig afterwards and turn off test mode.
Code:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
(reboot)
Thanks NeoJeo for the method!
For some reason, my friend's new machine have to use flashtool to create a ftf backup first after updating the official firmware . Using other kernels will fail and creates a bootloop. (Maybe carrier locked? No idea.)
Bootloop can be solved by re-flashing the stock firmware completely and redo all the steps again, so its quite safe.

You can always download the latest with firmware with xperifirm.

https://drive.google.com/file/d/0B7l5nu0bqYuGX19QcUl5VWdKOXc/view
Step by step reference for my friends:
1. download & install flashtool http://flashtool.net/download.html
^if doesnt work, then try https://www.dropbox.com/s/xyk493qa8psydrf/flashtool-0.9.13.0-windows.exe
2. install flashmode and fastboot drivers from C:\Flashtool\drivers
3. plugin your phone, make sure settings->security->unknown source and settings->developer options->usb debugging is checked at all times
(if cant find developer options, go to settings->about phone->build number, keep tapping build number to see what happens)
4. - If your already phone upgraded, then:
4.1 If you want to keep your current kernel for later use, see: http://forum.xda-developers.com/showthread.php?t=2334653)
4.2 download 31x kernel (4.1.2) from http://forum.xda-developers.com/showthread.php?t=2384512
4.3 save it to \Flashtool\firmwares
4.4 open FlashTool.exe, click Flash device -> Flashmode
^ to enter flashmode, either plugin usb without battery or plugin usb with Volume - while your phone is OFF
4.5 select the 31x kernel and downgrade
4.6 kill FlashTool.exe
5. download and run doomlord's rooter from http://forum.xda-developers.com/showthread.php?t=2327472
6. use task manager or cmd to kill adb.exe, if it is still running
- Now you have a rooted phone
7. download and run backup ta from http://forum.xda-developers.com/showthread.php?t=2292598 , keep the zip file for later use
- Backup TA only works with rooted rom
- If you want to use the latest andriod continue below:
7 download the latest firmware with xperifirm and bundle it with flashtool.
8. upgrade / flash your system to the latest version (see step 4, but use the latest firmware file instead)
9. get unlock key from http://unlockbootloader.sonymobile.com/unlock/step1
11. download andriod sdk from google and install http://developer.android.com/
12. open SDK manager, scroll down and check Google USB Driver then click install packages
^ if doesnt work, then try: https://www.dropbox.com/s/lgs2m90p1et87hx/platform-tools.7z
^ USB drivers is also avaible under flashtools/drivers
13. go to \sdk\platform-tools
(replace %key% below with the key from sony's email)
run fastboot.exe -i 0x0fce oem unlock 0x%key% in cmd
or create a plain text file and save it as a .bat with
Code:
fastboot.exe -i 0x0fce oem unlock 0x[B][I]%key%[/I][/B] [user=607132]@pause[/user]
^ If stuck at 'waiting for device', you can use flashtool.exe to enter 'fastboot mode via adb' (run Flashtool.exe -> Flash device -> fastbootmode
), then re-try the command above
^ while in fastboot mode, your phone screen is off and led is blue
- Now you bootloader is unlocked.
14. put this zip file into your external sd from http://download.chainfire.eu/supers...om/s/sy1vzzq9ygfvqvb/UPDATE-SuperSU-v2.01.zip
15. run Flashtool.exe -> Flash device -> fastbootmode
16. reboot into fastboot mode (via ADB)
17. after led turns blue, select kernel to flash and choose boot.img from http://www.mediafire.com/download/4bs9zy3z4sl1lvl/boot.img
^ if doesnt work, try: https://www.dropbox.com/s/y5is541wd5lck79/boot.img
18 click reboot device into system while pressing Volume +
- if LED does not turn purple at all, something must be wrong
- press Volume + as long as but NOT before the LED turn purple.
^ return to step 4 if needed, bootloader may be not properly unlocked.
19 select install zip -> choose zip from external sdcard
^ Volume+ - is up and down, Power is select
20 confirm
21 go to advance -> power off
22 remove battery and plugin usb to enter flash mode
^ Flashtool.exe should show the phone is connected in flash mode
^ But there seems to be a time limit where CM 10.1 remount itself automatically with the wired blue thing popping up and then crash
23 return to Flashtool.exe -> Flash device -> Flashmode
24 choose the .ftf either from the one in step 8 or the one you have downloaded
25 Uncheck anything on the "Wipe" colon
26 Check everything on the "Exclude" colon except "KERNEL"
^ You should now only have kernel.sin and loader.sin on the content colon
27 FLASH!
- if bootloop occurs, return to step 4 lol
^ alternatively you can just redo step 24, but this time "Wipe" everything and "Include" everything. If it boots, then jump right to step 14 and retry installing the zip
28 Install super su in google play
^ first boot may need battery in and usb removed
29 (optional) Re-run backup-ta to restore the zip from step 7 for Relocking bootloader (and check for rooted at the same time)
- if backup ta failed because of no su rights, return to step 4 lol
EDIT: do not re-lock bootloader if using the new img
EDIT:
Upgrading should keep your settings and stuff, unless something went wrong that you have to wipe data for a clean install.
Quick check list:
1. Most Important. Make sure you still have your bootloader backups.
Run Backup-TA to backup your current bootlocker if needed (new version here:http://forum.xda-developers.com/showthread.php?t=2292598). Backup-TA only works on rooted.
2. If you somehow lost it, re-obtain your unlock key from http://unlockbootloader.sonymobile.com/unlock/step1
3. Have your Flashtool and SDK ready (https://www.dropbox.com/s/xyk493qa8psydrf/flashtool-0.9.13.0-windows.exe, https://www.dropbox.com/s/lgs2m90p1et87hx/platform-tools.7z)
4. If you need the stock firmware from your carrier, remember to clear contents in something like: C:\ProgramData\Sony Ericsson\Update Engine\db\13740270\blob_fs and/or C:\ProgramData\Sony Mobile\Update Engine\db\13740270\blob_fs (or something similar in %appdata% for windows XP)
5. You can use any ADB backup tool or Sony Companion to backup your settings, best timing is right after OS update but before rooting.
To do:
1. Either upgrade with Sony Companion and use Flashtool -> SEUS Decrypt, or download by XperiFirm to create your own firmware (Will take a while to load depending on the power level of your PC.)
or just use the firmware people uploaded
2. open Flashtool.exe -> Flash device -> fastbootmode
3. reboot into fastboot mode (via ADB)
4. Unlock you bootlocker by running "fastboot.exe -i 0x0fce oem unlock 0x%key%" (%key% is your unlock key from Sony's email)
^ (Last time I checked, some people say they need to update SDK first.)
^ (unlock key may change after new firmware is flashed)
^ you need to enter fastboot mode via ADB first, or it will get stuck at 'waiting for device'
5. select kernel to flash and choose boot.img
6. click reboot device into system while pressing Volume + (press Volume + after the LED turn purple)
7. select install zip -> choose zip from external sdcard -> your-su-zip-file (http://download.chainfire.eu/supersu)
^ 'Volume+' 'Volume-' and 'Power'.
8. go to advance -> power off
^ If you get a boot loop, simply remove battery and plugin usb cable to enter flashmode and re-flash the new firmware again.
^ remember to re-enable "Usb debugging" under "Developer options"
^ tap "About phone" -> "Build number" 10 times to unlock "Developer options"

Thanks this works great but I am unable to successfully install a recovery with this method. Has anyone had the same issues??
Sent from my C5503 using xda app-developers app

Hello,
@awwer2002: After you succeed rooting the device did you install any recovery ? If yes, which one ?
@gmengass: Which recovery are you trying to install ?

[Q] Can Root Sony Xperia Z1 on 4.4.2(Kitkat)

Can I root z1 on kitkat??anyone can help me?

Yes,
First, ask QUESTIONS in the Question and answer section.
Now, read the several guides in the general and/or development section on how to root.
In brief
Either, unlock your bootloader and flash an insecure kernel
or
flash stock 4.2, root, install recovery and flash a prerooted 4.4 rom.
Alll instructions are in their relevant threads so I will not reproduce them here.
Eigth time and counting I have written this today

Anyone can explain why there is not an straight forward method to root Z1 directly on kitKat and we need to downgrade to do it ?

Best way to do is it to downgrade to 534 using flashtool, grab the FTF file needed from the mega collection thread.
Use vroot to root the device, install a custom recovery, flash the rom that you want to install (Monx, ihacker, romaur) then don't reboot, but re-enter flashmode and flash everything (without wipe) from an FTF of the same base, do not flash TA and System.
Reboot and youre done.
I wrote a more in depth tutorial which can be found in this thread, second post.

No that's not the best way
1) Vroot sends your IMEI number to china for no known reason. They have been asked to change this but gave no response to XDA about it.
2) The point of downgrading to a .534 FTF is that you can install recovery without rooting first. So install dualrecovery, then flash SuperSU.zip from chainfire, then flash a 4.4 rom of your choice.

It's real easy to relock the bootloader using Flashtool, so don't sweat unlocking it to root.

But how do you backup your TA that way.
You need to root first then backup TA. Relocking with flashtool does not restore your TA.
Once you have your backup then that is always possible, but not for a first time root.

I didn't know you could do it that way, the way that i've mentioned is what was written on all the tutorials that i've seen so i'm literally going from what other people have said, including monx.
The IMEI thing is a bit creepy but I wasn't aware of that either.

another one bricked...sigh how to fix?
Hey all,
Successfully unlocked my c9603 with latest kitkat and installed cwm 6 with these instructions
How to Install CWM 6 Recovery on Xperia Z1:
Download Doomlord’s Advanced Stock Kernel with CWM Recovery
Copy the downloaded.zip file to your phone’s sd card.
Extract the downloaded .zip folder on your PC, you will get a Boot.img file.
Place the extracted Boot.img file in the Minimal ADB & Fastboot folder that you created using our ADB & Fastboot Quick Setup Guide.
If you are using Android ADB & Fastboot full package, you can place the downloaded Recovery.img file in the Fastboot folder or in the Platform-tools folder.
Open the folder where you placed the Boot.img file. E.g Minimal ADB & Fastbootor Fastboot or Platform Tools.
Press and hold the shift key and right click on an empty area within the folder, and click on “Open Command Window Here”.
Turn off your Xperia Z1 completely.
Now press the Volume Up Key and while keeping it pressed plug in the USB cable.
You should see a blue light in the notification light of your phone, that means your device is now connected in Fastboot mode.
Now type the following command: Fastboot Flash boot Boot.img
Hit Enter and it will quickly flash CWM 6.0.4.6 recovery in your Xperia Z1
Once recovery is flashed, now issue this command “Fastboot Reboot”
Your device will reboot now, as soon as you see the Sony logo, and the pink LED, press Volume Up key to enter recovery.
Congrats! You should now see the custom recovery.
Once in CWM recovery, flash the zip file you copied to your phone in step 2. To do so, select “install zip > choose zip from sd card > doomlord advanced stock kernel.zip > yes” and flash it.
Once flashed the zip file, reboot your device.
That’s all.
ok so I did all of the with success now when I turn my phone on I get what I think is a bootloop mode...it gives me the sony logo and the pink led to boot in cwm then re loops over and over.
I can get into cwm but thats it.
So how do I go about fixing my bricked phone now? Kinda need it lol
appreciated guys

WOW, I misread that...
If you flash doomkernel you already have recovery.
Please link to where you found those instructions, they seem way out of date.
and have you unlocked your bootloader?

Those non xda guides are crap...
If you have unlocked your bootloader (Did you make a TA backup first?) then just flash doomkernel
Doomkernel has recovery in it.
Once you have done that you are rooted and have recovery

No, I didnt back up the ta as I didnt have root in the first place.
I have doom kernal installed and can access cwm.
It is stuck in bootloop mode...how do I just get my phone to boot normally for now instead of bootlooping?

If you flash a new (base)rom on your device it may not automatically wipe your dalvik-cache, This means your old dalvik-cache will be used for the new system files which would result in a bootloop, to fix this problem:
1. Start your phone in CWM Recovery
2. Go to Advanced
3. Choose “Wipe dalvik-cache”
4. Now go to “Mounts & Storage”
5. Choose “Wipe /cache”
6. Reboot your phone
Note: by wiping “/cache” and “dalvik-cache” you make sure it’s completely deleted, some roms use /data and some use /cache for the dalvik-cache
If the problems still exists after doing that, you could try to wipe your /data partition. before you do that first make a backup of your phone (in it’s current bootlooping state)
1. Start your phone in CWM Recovery
2. Now go to “Backup & Restore”
3. Choose “backup” (it may also be called “backup to internal/external sdcard)
When that’s done you are free to wipe /data, you can achieve this by doing:
1. Now go to “Mounts & Storage”
2. Choose “Wipe /data”
3. Choose “Wipe /cache”
4. Reboot your phone
If the rom still doesn’t boot correctly it’s probably the rom which isn’t working, contact the rom creator then and try an other rom for the meanwhile.

Ok, flash SuperSU.zip from chainfires website (Google it)
Then flash a new rom of your choice.

Cool, ill get onto that. Ive noticed a cpl of roms floating around xda. Any suggestions on a good one or run with the

lol....might as well pick a good rom since i have stuffed my stock one.
I still will achieve my root! haha
thanks for the help so far, its always appreciated!

You do not need root to flash that.
Its a stock FTF, just flash it in flash tool

sorry I wasnt saying do i need root for this? i know i currently dont have root and can flash ftf anyway.
what i was saying was, once i have my phone back up, I will achieve root status on it...
so if I am correct flash the phone with supersu from sdcard via cwm6 then flash
[FTF] Xperia Z1 C6903 14.3.A.0.681 Commercial&Journalist
which I am downloading from http://forum.xda-developers.com/showthread.php?t=2687275
My phone should boot up now with root access, but I am only trying to fix it currently.
Cant see why I wouldnt have a working phone with root following these steps?
thanks , ill keep posting updates, might even help someone else in the process

But why are you insistent on backing up a system that is in bootloop? Why would you ever want to restore a bootlooping system?
I would just do a fresh system install and forget about backing up a non working system
Just flash the FTF of your choice, then the appropriate DooMKerneL version.
Then you are rooted and have CMW installed. 2 easy steps, I really don't understand your need to backup first, especially when your phone is bootlooping.

No, once you flash a FTF you lose root. You will need to reflash the appropriate DooMKerneL again

im not trying to backup the bootloop, i just want to fix my phone. I did not realise you were saying fresh install then start from scratch with the root process.
So I will flash the NEW ftf to my phone. Once phone is working I will flash doomlord kernel and supersu. thanks for the help. do you happen to know a link for the correct instructions for this, so I get it right this time.

Rooting from .101 walkthrough

This is the first time I root/flash my Xperia ZR from .101. This post is to document how I rooted my phone and the problems I encountered.
Tools I used:
Helium - App Sync and Backup
https://play.google.com/store/apps/details?id=com.koushikdutta.backup
Flashtool (Windows Installer)
http://www.flashtool.net/index.php
Backup TA
http://forum.xda-developers.com/showthread.php?t=2292598
DooMLoRD Easy-Rooting-Toolkit v17
http://forum.xda-developers.com/showthread.php?t=2327472
XZDualRecovery
http://forum.xda-developers.com/showthread.php?t=2261606
ROM/files used:
[Stock ROM][LB&UB][4.3] Rooted, Deodexed & Zipaligned Stock 10.4.1.B.0.101
by IJskonijn22
http://forum.xda-developers.com/showthread.php?t=2713073
C5503_10.1.1.A.1.310_GLOBAL-LTE.ftf: which can be downloaded from the above thread
C5503_10.4.1.B.0.101_Generic NL.ftf: which can be downloaded from the above thread
Idea:
1. Downgrade to .310
2. Root it
3. Install Recovery
4. Flash rooted .101 ROM
Steps:
1. Backup all the data in the Internal Storage
2. Backup apps data using Helium - App Sync and Backup
3. Install all Flashtool and driver
Flashtool comes with drivers installer. I checked "Flashmode Drivers", "Fastboot Drivers", and "Common drivers Lagan, Fusion3 board"
4. Enable USB Debugging
5. Use Flashtool and Flashmode to downgrade to .310
When asked to hold "back buttom" and connect the USB cable, hold volumn down instead.
6. After booting into .310, enable USB Debugging Mode and UNKNOWN SOURCES
7. Make sure you close Flashtool in your PC
8. Run runme_win.bat in DooMLoRD Easy-Rooting-Toolkit v17 and root the device
9. (Optional) After rooting, backup the TA in case you need to unlock the device in the future.
10. Run install.bat and install XZDualRecovery
11. Copy the ROM zip file to the SD card and flash it using Recovery
12. Swith Off the device
13. Use Flashtool to flash C5503_10.4.1.B.0.101_Generic NL.ftf, CHECK exclude system
14. Boot and after 1-2 minutes, reboot the phone
15. Restore apps data
16. DONE
Advice:
1. Take some screenshots for the homescreen before everthing, so you can put the apps icons back to where they were after rooting the phone
2. Check MD5 checksum of the files downloaded
3. Make sure the battery of the PC and phone are enough
4. Download everything before you start
5. Have fun
Some problems I encountered:
Problem with MTP/MSC USB Mode:
MTP mode seems cannot be used with Flashtool. For .101, you can find them in Setting->Xperia->USB Connection.
Using DooMLoRD Easy-Rooting-Toolkit v17, got stuck at *daemon started successfully*:
1. Make sure ADB driver is installed
2. Make sure no other adb.exe process is on
3. Make sure USB Debugging Mode and UNKNOWN SOURCES are enabled
4. Try Restart PC
5. Try uninstall drivers and install again

Hello,
for all fellow ZR users: you do not need to downgrade your ROM version to root it.
here is a simple way, you will only need Flashtool, Cyanogenmod kernel, SuperSu zip and original .230 ROM kernel
1 Backup TA, link provided in first post (this is optional but highly RECOMMENDED)
2 Unlock Bootloader, you will need flashtool and code from Sony
3 Download SuperSu and place it somewhere on your device
4 Flash boot.img from CyanogenMod 10.2.1 (unzip and flash only boot.img using fastboot mode - USB in holding vol+ while device is powered off)
5 Boot into recovery (power on, hold Vol+), choose "install zip from SD card", find where u placed SuperSu zip, install it and power off the device, do not do anything more
6 Connect device in flashmode (USB in holding vol- while device powered off) and flash the kernel form your 10.5.A.0.230 ROM (or any .230 ftf for that matter, for ex. this). Flash ONLY kernel, uncheck everything else.

And if you dont have a ta backup you still need to downgrade to gain root.
If you dont you will lose the drm keys and bravia.

This is a way to root a ZR which includes unlocking the bootloader, it is clearly stated. Unlocking your bootloader is supported by manufacturer since it is Sony who provides you with a key. So I suppose it is no more unsafe than any other operation with the device, although yes it voids your warranty. That's why making TA backup is recommended, one can relock the bootloader easily with it.
If one's priority is safe play, do not proceed with flashing and rooting in the first place.

sijav said:
well that's interesting that you had restored your TA without downgrade. I couldn't.
alright I just translated with google, did you mean: derogate = void? cumbersome = bloated? and lengthy = too many steps? please correct me if I'm wrong my English is not good.

Derogate means belittle, make something appear less than it is. This is what you've done on Thibou's thread and here. It also means not being able to discuss thing in civilized manner, swearing and insults.
Cumbersome means inconvenient or too complex.
Lengthy means taking more time than one would expect

thanks for full translation of those words

This method works with prerooted 4.4 too.
If you want to backup your TA, root is required. And if you are in 4.3/4.4 already, you need to downgrade to root your device tho.

Hi , Everyone is saying one different method. Please give one method. That we will follow. I am really confused by seeing different methods. Don't understand a bit

It's easy all you have to do is reflash your software using flashtool by Androxyde
Download the flashtool
Search for ftf file for your country or global
ftf file: it's software file created by flashtool to flash sony software
After download and install flashtool go to
Your_Windows_Partition:\\flashtool\drivers
And install drivers for your device ,flashmode and fastboot mode
Note: if you have win 8 or higher you need to disable signture virification to install drivers
Then open flashtool and click on lighting button and press flashmode then select the folder of your ftf and flash
Note: before flash there is list called exclude check TA in this list then flash
Wait for flashtool to prepare files then after popup message put your phone in flashmode
Flashmode: connect USB with vol down pressed and wait for flash
Be aware cause flashing software wipe internal memory
Note: you mentioned that you have unlocked bootloader
You can download any custom rom like Cyanogenmod and put on sdcard and install using TWRP
hit thanks if helped

Flashtool doesn't work well now, so can I downgrade from N to MM?

I'm on the stock Nougat now with locked bootloader. I'm planning to downgrade to MM so I can backup the TA, but i heard flashtool have problem downgrading phone that is already on Nougat, and I guess sony pcc wont help me to downgrade to MM, so anyway I can downgrade?
Thanks

I did that with no issues. From N to MM you need to flash full firmware, that means: excluding nothing, wiping everything (all your data will be lost).
Do exclude *.ta files only (If any is present in ftf)!

Ok, thanks for the info

@serajr please can you tell me how Flashtool works and Xperia X series are not listed in the device lists? everytime i try to flash my phone it asks me to choose my model name (Xperia X) which is not listed in the flashtool supported devices...
also, when i browse to choose the FTF it doesn't recognize it.. i downloaded it from Xperifirm, and did all the bundle in Flashtool.
I have:
latest flashtool installed
installed all drivers in flashtool and in computer for my Xperia X
USB Debug and unknown resources are checked.
everything is well installed!!
please if you can help me or tell me how i can flash my Xperia X ??
give me information or guides...etc
i appreciate your help
thank you

@Nidhal AKA the king
This is basically what I do:
1. Open Flashtool with device disconnected from usb port
2. Click "Flash device" button, choose "Flashmode" and choose the firmware
3. Click "Flash" button
4. When prompted to connect the device, connect it in flashmode (plug usb cable with device's volume down rocker pressed, and release it after the flash process starts)
5. Choose "No" for script (if prompted for)
6. Wait till it finishes!

I've unlocked and I'm still at MM now
Can I get back to nougat? coz sony wont update for me now and flashtool have problem

Same, you need wipe everything.
1.relock bootloader by flashtool
2.flash MM6.0
3. use sony pc companion to upgrade.
4. you get nougat.

@serajr
the Xperia X is not available in the lists of flashtool supported devices.. i tried that and it keeps popping up a menu to choosee phone model (X not available) when I ignore it gives the error loader.sin not found and flash cancelled...
that's in the previous flashtool version... the latest one when i browse the FTF for Xperia X, it doesn't even see it in the firmware folder as there is no FTF file!
any trick or solution to make the flash successful ?
thanks!

I find out how to do it now, u need to exclude system.sin when u flash the system, afterwards flash the system.sin as system.img
The convert is complex as **** (at least for me) anyone wants the system.img just give a shout i will upload it
