There's something seriously weird about this box: I eventually tried to flash FW006, USB burning tool hangs for minutes at 25% then stops with an error. I tried a flash with full erase, and it did the same. I recalled I had root at some point, so flashed to FW006 + root, and that worked. Boot (takes a while), then check FOTA: no update available. Checks that root is indeed off (switch it on and off again), try to reboot the box, and it won't boot again at all.
This box is mental, trying to figure things out is complete guesswork. I never had this kind of malarkey with any Minix boxes before.
*EDIT* unable to get to recovery either, so trying to flash with USB burning tool again!
*EDIT 2* tried to burn FW006 non root again. "Surely going from FW006 root to FW006 non root will be no problem he said". Ah! Now trying to burn FW004!
*EDIT 3* managed to burn FW004 (failed 1st time, so tried again!), then FOTA to FW006A, and now FOTA tells me there's no update.
