My wife's school has at least or almost 200 of them, they decided they were shit and put them in the dungeon (storeroom). I'd like to revamp to let the kids use them again? But according to internet people and Reddit the firmware is locked down and can't be unlocked so I can run Linux?

Do you know if you can do it? I have machines to test (When I get a charger from ebay)...

Cheers,

Pavle.
