Please don't ask why (the answer will be: "because I'm stupid"), but I relocked my bootloader and now my Swift 2 Plus won't boot anymore. When turning it on, it vibrates and the Wileyfox logo flashes for less than a second. After that the screen stays black and nothing happens. Same thing when I try to boot into recovery. I can only boot into the bootloader but I can't flash any images or unlock it again ("FAILED (remote: oem unlock is not allowed)").
Is there any way I can revive my phone or is it lost?

I think your only way is to flash twrp again with fastboot install method :
//twrp.me/devices/wileyfoxswift2.html
And then flash the stock rom :
//cyngn.com/support
hope it will helps you!

Sorry, I'm a new user so I can't post link, you've just have to ad "https" at the beginning of the line.

Thanks for answering, but I can't do that, because the bootloader is locked and protected from unlocking. I guess the only thing I can do is ask the support if they can provide the mbn and xml files that are needed for unbricking with QFIL (I can boot into edl mode as I recently found out). They probably won't but it's worth a shot.

If you use the signed zip ( not the fastboot image) the default recovery should be able to install it.

It doesn't boot to recovery. Only fastboot and edl mode work.

Thanks, but that doesn't work with a locked bootloader (already tried).

It seems like the only way to revive it is with QFIL, but for doing that it needs the matching mbn and xml files that aren't included in the factory images. Wileyfox support wasn't helpful, either.

Can't we put the dirty cow bug to a use now? It should work on the phone unless it has the latest security patches, right? And with root privileges you should be able to flash a new recovery or reset the phone.

I'm actually not sure, if I still have root privileges. It could be that I turned it off inside the SuperSU app.
I tried to flash the stock rom and that didn't work, though. Do I have to do something different than usually to flash with root privileges?

I read a little about dirty cow, now (didn't know much about it before), but if I understand it right, I need adb to upload files onto the phone, right? Sadly, adb doesn't work. Only fastboot :/
