I try to update Orion 102 tablet android version with next version published by manufacturer
using update manual: orion-102_08d8c3c8f870e7e3f1e57ef8ac5157b946026642.pdf
and update file: R1042BK_ORION102_20140725.rar Android 4.4.
1. Charge the device battery.
2. Open RkBatchtool (V1.8), and select firmware
3. Connect device in Flash Mode
Go to additional Storage settings. Change USB connection mode to „Mass Storage”
Now click „Switch” button, and wait to change notification color to green.
In moment to press Switch button tablet restarting, and not change notification button to green.
From this moment, update not working.
How it's possible to update from Android 4.2 to newer version ?
P.S. External link not working for me to add source of software and update manual link.
