Thank you Jessie, this totally made my day! The device is now displaying Chinese beautifully. You guys are truly geniuses! Many thanks to both you and scottjin
For those who are interested:
As I've installed the russian version of Boroda 1.05f, I thought it would be safer to flash back to the official version first. The program ran alright (with a little tweak of version number), but the Boroda was still there when the device restarted. So...I decided to go ahead with the Chinese version anyway (not the smartest thing to do). Luckily the system didn't seem to mind and my Chinese books displayed alright. Not what I would recommend people to do though. If you are in the same boat as me, better wait till you are sure there's a way to go back.
