After updating my M96 Universe , I've got serious issue with the battery, it drains super fast, it serve less than a couple of hours, and suddenly the device freeze and won't work tell I connect it to power supply and reboot, moreover battery indicator doesn't give correct battery percentage it always shows 100% or 99% tell it freeze, and then when I put it in charging it jump directly to 100%, it seems that this is battery issue, but this problem happened only when I update firmware through onyx boox international site "Firmware for Artatech_M96Univerce V1.7.5_rc1" dated on 30 may 2016.
First time I made the update I've got the issue, so I contacted Archatech, sent them the device, and they change the battery for me and reformat it to original software, then the device works perfectly, the battery life was about 1 month of moderate use, till I decided to upgrade it again, and the same problem comes again directly after updating.
Now I couldn't use the devise since it requires charging several time a day, can anybody provide me solution for this issue?
Or can someone tell me how can I retract the update and rollback to original software?
