Hello everybody,
i have an Xperia XZ F8331 with android 7.0 and i want to install another region software because this is with some apps preinstall and i want to flash it. I have to say that i try 3 versions of software, but the same result. When i connect the phone i recive the following error:
31/001/2017 14:01:38 - WARN - No loader found or set manually. Skipping loader

does flashtool pop up a message to you as soon as you plug it in for starting the flash process?

well, this little window message is about "script " to use... and you have to click YES... if you click No, you'd get that error or similar one...


what build numbers you were trying to flash?

i flashed Nordic Generic with no bloatware... except AVG anti-virus and those typical google apps (just disable them) so it's pretty much clean rom!


also go to devices same folder where firmware is stored... and go to XZ folder and check if you have all the required files... just screenshot all and send in here , and lets see how i can help you :cowboy:

Thank you for your answer. When i connect the phone flashtool doesn't pop up any window, just stay for 10 seconds, and for the first time i was tinking that is working but, after that i recive the error. On my phone i have android 7.0: 39.2.A.0.386.
I try with following software:
Xperia XZ_F8331_39.2.A.0.361_Nordic_Generic 7.0
Xperia XZ_F8331_39.2.A.0.374_Australia_Generic 7.0
Xperia XZ_F8331_39.0.A.3.30_Central Europe 1_Generic 6.0.1
and i revice the same results. I have to say that i install drivers from Flashool folder and its all good.

ok go to that folder: C:\Users\yourcomputername\.flashTool\devices\F83XX

and you should have some script files exactly like in the attached picture below!


if you don't have that folder... try to uninstall Flashtool and start a fresh installation....


but if you have, you need to create a flash-script otherwise the flashing will not gonna succeed at all....


now, follow the steps carefully.... believe me, its so easy...


first off,

make sure flashtool isn't running (if so, close it)

we're going to select the ( F8331_39.2.A.0.361_R5C_Nordic Generic ) for flashing... it's good and it doesn't have bloatware...
(i flashed it in mine)


2- go to the folder "Devices" scroll down to F83XX... open it, and you will find some .fsc files



copy the name "F8331_39.2.A.0.361_R5C_Nordic Generic" (this is how i have it, if the name you have is different than mine, then use yours....

and then go to that script -> F8331_39.2.A.0.327.fsc then rename it and overwrite with the same one we copied (the one you will use for flashing)

then open flashtool for flashing... wait until the window pops up asking you to connect your phone for flashing... then put your phone..... a message will pop up notifying you about "a new script was detected and if you want to use it" click YES or OK.. and then wait, and hopefully it will continue the flashing process successfully...


Good luck and let me know how's everything went :cowboy:
