My curent noob question is now that i have my DRM img successfully backed up, i'm not sure from those threads how to actually restore it back to stock if i wanted to (i have only unlocked, not rooted).

Do you just copy the TA/DRM backup img file to phone and use twrp to flash it, or are you supposed to connect the phone to computer and boot into fastboot mode where you run adb commands from the pc? Have been searching but not found any explicit examples, just mentions of 'flash with the drm img back to stock'.

In the thread of the backup tool, there is a command that you can use to restore DRM keys, some people do with TWRP in the terminal, or connected to the pc with adb

After restore DRM keys, you have to flash stock rom to boot

Thats good to know. So as long as bootloader is unlocked and we use unsigned ROM (AOSP, SailfishOS etc.) we don't need (and don't can) restore the DRM-Keys ?

I tried to flash it with the Androxyde Flasher you suggested. It took me a while to get the right driver, indeed. The Device Manager is happy in Windows 10, no unknown devices any more.

But it won't flash yet.

That's right, or custom roms based on stock, so... You will restore DRM keys and flash stock rom just to let your phone as it was never unlocked

Did pop up a message that told you to use a fsc script? If so... Click yes and try to flash again

Yes thats normal. It tells you this message every time you load a new Firmware for flashing.

I flashed mine with XPeriaFlashTool under Linux

I found this question on GitHub: https://github.com/Androxyde/devices/issues/53 in which someone asks why he cannot flash the F5121 with Androxyde. He states he did manage with an earlier version: "I only flash successfully with an older version F5121_34.0.A.2.301 using 34.0.fsc script."
So it seems I had the wrong ftf to flash with. I will have another go with this version: https://easy-firmware.com/index.php?...egory&id=18692, at the bottom.

I suggest you to use Xperifirm from Flashtool, there it create the ftf after download is completed, that's how I flashed my Xperia X

OK, I will. Did you use a flash script? Androxyde Flashtool keeps saying:
No flash script found.
Flash script is mandatory. Closing session

(Which is weird as in ...\.flashtool\devices\F51XX there are 3 .fsc files)
