This app was created for ZTE Spro 2 (MF97x) projectors only.

When your Spro 2 projector started to show this warning message:

"The battery life-cycle limit reached. Please contact the after-sale service to change a new battery. Projector will turn off in 5 minutes."

If after-sale service could not help you, battery removing or replacement, hard reset and firmware update most likely will not solve this issue because, in our opinion, this is a planned obsolescence built in by manufacturer.

But don't worry, our app can help to recover your device functionality, save you money and avoid of buying an expensive brand new device.

Important: you need to root your device before using this app.
