Title: Flashtool on Windows 11
Post by: FredL on October 13, 2023, 10:10:19 am

I've just successfully flashed my Gemini, but to get it to get the FlashTool to recognise the Gemini I had to disable memory protection in Windows 11:

Windows Security > Device Security > Core Isolation

After a Windows reboot the Gemini could be flashed. Just reporting here in case anyone else has the same problem in future.

To turn on Core Isolation again afterwards I had to remove the FlashTool drivers (slightly technical, but a quick google solved the issue)

Thanks for this useful hint! I wonder what does OS' memory protection have to do with a flashing tool...

Would be worth adding this to the `shymega/planet-devices` wiki as a PR.

Likely to do with the driver for interfacing with Mediatek's preloader. This isn't unusual. But I wouldn't trust it with a five-foot pole... it doesn't happen on Linux, but it could do, if it was a hardened kernel.

I've never had this happen to me though.
