@knc1 @NiLuJe @ixtab Thank you all for the replies, esp. @knc1 for a comprehensive explanation!
My device's serial is:
B024 1604 3263 XXXX
For the hack's UI messages, English is okay. I just want to hack the device to tweak fonts for better Chinese rendering.
After jailbreaking, I can use the USBNetwork patch from this @NiLuJe's thread, right?
