Only issue I have is the power off power on. The Power Off works fine the Power on does not. Then when I power it on manually it gives me a sysytem error occured but powers up fine other than that
Hi all.J m the new on the forum. I just got the Lenovo A850. The first thing it wanted to do is download the OTA Firmware update. It failed!
Has anyone had the update work successfully?
Where Does the update file get downloaded to?
Is there a way to force the update because an update available does not show up in "about device".
The only way I know for it to force the OTA again is by doing a factory reset then that is one of the first things it asks you to do.
Thanks
