Then, start your flash tool

Press the flash button, Select flash mode

Select the firmware & Leave all the settings as it is i.e. wipe data and cache selected, Select No final verification[I selected it, i don't know whats the use of it can anybody tell me ?? ] [After searching google i got this answer : It will check whether any error occurred during flashing, i had disabled it when flashing stock rom on my phone. so idont know what happens when we keep it unchecked.]

The flash tool will setup files and start flashing, Don't touch your phone or press any button.

Hurray you have successfully recovered your phone back to stock state. :highfive: :fingers-crossed:

Have you solved the issue? In case you didn't, both flashtool and Sony's command line procedure works, so choice is yours.

I want to give some information to everyone reading this. After unlocking bootloader, my device got stuck on a bootloop. I tried the advice given here and flashed the latest stock firmware but it didn't help. Then I relocked bootloader but still no luck could not get out of the bootloop. Then I tried to give stock firmware another shot but this time I checked Wipe USERDATA and Disable Final Verification, and this time IT WORKED! My guess is that it's about wiping USERDATA so if anyone encounters an issue like this, give this a shot.

Hi All,

I tried unlocking the boot loader with the officially mentioned fastboot method and have ended up in a bootloop while starting the phone.

As mentioned in this thread, I am trying to flash the stock ROM C2105_15.0.A.1.31_CE.ftf onto my phone. However, I am getting an error message "No available services matched the connected device" on the EMMA tool. I tried the following:

1. Tried putting the file C2105_15.0.A.1.31_CE.ftf in C:\Program Files\Sony Mobile\Emma\firmwares folder, but EMMA doesn't recognise this.
2. Tried putting the file in C:\Flashtool\firmwares, still EMMA doesn't recognise this and shows "No available services matched the connected device".

I have attached the screenshot of the error message herewith.

Please let me know how I can resolve this issue.

Thanks.

yeah mee to i am getting the same error

Yes you should wipe data (this why factory reset work instead of flashing the whole rom) cause the cache is set to null so you need to wipe it to rewrite the cache.

Try this version of flashtool 9.11.0
It will probably work and don't forget to install the drivers in the driver folder of flashtool .
Good luck.
