My T68 is on 175rc1 and I have experienced the odd sudden battery discharge, so I'd like to update and see if it is fixed. I saw that 175 was released on 2016-10-17 (
http://ereader-store.de/en/content/8-downloads).
Unfortunately my T68 does not recognize this as a valid update file. I opened it in 7zip and in "android-info.txt" it says "board=T68ML"
Previous updates from this site said "board=T68"
So, the question is: what really is the difference between the T68 and T68ML?
(I bought mine in 2015 while visiting China and on the box it says T68ML, but on the device it says T68, so I've always been puzzled about this...)
