Yes. Or actually I've tried so many different links that I'm not sure anymore. I'll try one final time just to make sure.

What you can try to is :

Create a folder : .flashTool/mydevices/F51XX/

in the tar file I uploaded, there is a fsc file. Extract it
and copy it here:


.flashTool/mydevices/F51XX/
.flashTool/devices/F51XX/

Then, close flashtool and launch it again and try flashing again

Good luck

Unfortunately even this didn't work. Same boot loop as a result.

I was frustrated looking at programs whose purpose wasn't clearly stated, and instructions which say 'do xyz' but don't state what the purpose is, or what the expected result is.
I've yet to do this myself, but trying to make sense of docs. It would be good if someone could do a video of some of the steps to downgrade using official Sony image to help understand instructions.

Happened to me once with one SE device. Used Xperia Companion from Sony to fix it.

I wonder if whether it works correctly, fails alltogether to flash or goes to brickloop depends also on the variant existing on the device?

Using the "Xperia Companion" is a no-no since it is a windoze tool.

---------- edit ----------

I kind of thought the whole point of flashing a device that has a locked bootloader is to do it so that only official Sony-signed images can be flashed... so either it flashes or not but is impossible to brick...??

Hard to believe that I was just lucky so here is the process that I did with my Xperia and Opensuse PC. Hope I remember it all.

- enabled usb debugging and allowed application install from usb in Xperia original android 7
- downloaded flashtool for linux and applied the update available on the flashtool page
- downloaded Xperia scandinavia image version 6.something from the link I gave earlier
- downloaded madcows DRM backup script
- started root shell with "su - root"
- installed adb with "zypper install android-tools"
- plugged in Xperia
- tested that "adb devices" works
- unplugged Xperia
- shut off Xperia
- held volume down button and plugged in Xperia
- launched Flashtool as root
- browsed and opened the Android 6.x what I just downloaded
- used flash mode
- selected all wipes
- watched it update
- rebooted Xperia, set the new user mandatory settings
- enabled usb debugging and install apps from usb
- executed madcows DRM backup script

Never had a glitch. Did I forget something?

I've also wondered whether there are multiple versions of Xperia X with subtle differences that could explain failure. My box says revision 4, which suggests there is other revisions.
