[Guide] Flashing Any Firmware for Any Xperia Phones

[Kuarinfou]

Hello everyone. This is my quick guide to flash the firmwares available to your phone WITHOUT UNLOCKING BOOTLOADER (this is important especially to change the region). Before doing this, you should get the drivers of your phone, i did it with connecting the phone with Xperia Companion and it installed automatically.
You need 2 apps to do these operations:

1- XperiFirm from Igor Eisberg
2- Flashtool from Androxyde

Downloading Firmware Using XperiFirm
-Select your device from left row.
-Select the firmware you want and download it.
-When the download finished, the folder will appear where you selected as download directory. We need to convert the firmware to FTF file.

Converting Firmware to FTF File
-We'll use Flashtool to doing this.
-Open Flashtool, select Tools --> Bundles --> Create
-Select source folder as your firmware folder, select your device by double-clicking the blank (because of here is XZ forum, select F833X but i think this will not interrupt anything). Write your region to Branding and your version to Version
-When you select source folder, in folder list which is on the left there are some .sin files should appear, if it does not then check if you select the source correctly. Then select all .sin files and move to right, then press CREATE.
*Please check notes if you see FSC script found.

Flashing the Firmware
-Press Flash Device (the flash icon on the left side), select Flashmode, select your firmware from Firmwares.
-In Wipe, Sin section (not exclude), select all boxes, DO NOT SELECT SIM-LOCK, then press Flash. Wait for Flashmode screen should appear when the operation finish.
-Turn off your phone. Press Power and Volume Keys and Connect the Phone via USB Cable AT THE SAME TIME to put the phone to Flashmode, the LED should blink Green and Flashtool will do its work. When it says "flash completed, restart your phone.", restart your phone. Your new firmware is ready to use

NOTES:
-In creating FTF session, sometimes "A FSC script is found: xxx. Do you want to add it?" appears. Press Yes if you don't have another flash script.
-If in flashing session, "No flash script found" error occurs, then you need a flash script which comes with the firmware. Usually this script should come with firmware which you download from XperiFirm, if it didn't, try another firmware.
-If you completed your flash but the phone does not reboot and says "The software update failed." or the flash session does not complete successfully, then flash the firmware again. This occurs, i think, because of the encryption of Android (This happened to me twice when i downgraded from Oreo to Nougat).
-If you have a FTF file, skip the first 2 steps.

what's version? version of what? does it means the fw version? (for ex. 41.3.A.2.184 about italy fw)
In the branding's field, is correct to write the entire name? (for ex. "Italy" with major and minor letters)
Thanks

Version is the firmware version which named by Sony (like 41.3.A.2.184) not the Android version, and the branding is the region where the firmware is made for (like DE for Germany or TR for Turkey). You do not have to fill the blanks correctly, because it's just for remind you what the version or region of firmware is if you have multiple FTF files.
