Here is the new 2.01 firmware revised by spanish Hanlin resellers. Usually their version works nicely. It also has the option to switch to English, but is in Spanish first.
REMEMBER TO BACKUP ALL YOUR BOOKS BEFORE UPGRADING. There has been some issues with upgrades deleting all content of memory.
Tried it, seems solid so far last 10 minutes
By the way as a WAG I would say that all firmwares are jinke's with some revision by the resellers, so probably very similar. I have tried different resellers firmwares and all worked on my Spanish version of the HanlinV3.
SALES! Check out
this Hanlin for 279€ I don't know if they sell outside of spain, but it's a good offer
