I have a new Sage. It was running firmware version 4.30.18838. I did not like the fact that when you plugged in the charging cable that the light went off after a few seconds. I also thought that the reader orientation menu seemed to pop up every so often while I was reading and had turned the eReader orientation.

I decided to roll back the firmware and did so by connecting the USB cable and dropping the old firmware (4.29.18730) into the .kobo directory. I ejected the device and it "updated" the firmware. Everything appeared to work well and the device said it was running the 4.29.18730 firmware. The power light stayed on when it was connected to the USB charger and when I read for about an hour last night I never had the orientation menu pop up. Everything looked great. I pressed the power button on the back of the eReader and put it into Sleep mode and went to bed.

This morning when I got up the eReader said LOW BATTERY 1%. I've never seen this before. Either I have a flaky new Kobo Sage or downgrading the eReader this way caused some battery drain problems.

Beware if downgrading the firmware in this manner.

Once I get the eReader charged I'll do a true factory reset and see how that works.

TL;DR - Downgraded Sage firmware - battery went to near zero overnight.
