alt Hacker NewsThere are 10+ comments here praising a third-party firmware, so I think it deserves mention that this might (?) no longer be possible for new devices,

> "But now buyers report Xteink is blocking [CrossPoint Reader], which might depend on where you live and where you purchase its devices. [...] Instead of being offered a replacement, they received a statement they shared to Reddit explaining that recently shipped devices from Xteink now come with firmware flashing disabled."
IIRC this is mainly ones sold by third-party vendors in China? Like if you buy from AliExpress.
EDIT: if you look at the Reddit post the article references it even says:
> !!!!!THIS ONLY APPLIES TO LATEST CHINESE STOCK AND NOT THOSE THAT ARE BOUGHT FROM XTEINK.COM!!!!!
Also note that CrossPoint has a way to bypass said flash block if you look at their repo or website:
