I think mine is in the clear too. My
Lite+ might have came directly from the factory recently because the wandering is very minimal. I'll be performing more tests tomorrow but I think I got lucky.
As for the firmware update, holy ****. What an arduous task. It failed 5-6 times in a row (never even getting to 1%). Then after the 6-7th attempt, it commences to download BUT fails after 3%. Finally around my 11th attempt, it starts to download but it takes FOREVER. Then... it fails to 40% (downloaded at that point but still needs to be uploaded and installed to the
Lite+) twice in a row. The whole ordeal took about an hour to complete
