[Lenovo Yoga Tab 2 Questions & Answers] Xresdas:
So, my tab was working perfectly and it just went off. after leaving it for a few months, i decided to charge it and when i turned it on i get a flickering error message, it goes off and turns on with 'fastboot starting....'

So i did my research on it and i tried adb, fastboot commands - like reboot, continue...nothing worked. then i downloaded the flash tool got the appropriate drivers and installed them. but i keep getting this message
