When you try to update the system from 1.2 to 1.32 firmware. Someone can easy to done but someone encounter "Fel2Fes Error" and fail to update.
The problem is caused by OTA function. This tablet like other manufactory to provide OTA update the system on air. Alternatively, you can update through the computer manually. Currently, Onda V812 still provide 1.2 firmware only for OTA. For 1.32 firmware, you only can do by using computer. Facing this problem if you did updated to 1.2 by OTA before. Update to 1.32 can been done if update 1.2 by using computer.
So, very simple to fix this problem by do again update 1.2 by using computer instead of OTA. Then you can update to 1.32 firmware.
