If you are happy owner of ZTE Spro 2 (MF97x) android projector, this app is a "must have" for you! We believe that this device has a built in obsolescence and sooner or later you will come across it. The issue appears as a warning message: "The battery life-cycle limit reached. Please contact after-sale service to change a new battery. Projector will turn off in 5 minutes". Most likely it can not be solved by contacting after-sale service as adviced in the message (but anyway we recommend to try that first). Battery replacement, hard reset or even firmware update may not help as well. We have tried a lot of things before found a working solution. Now we are happy to share our Spro 2 Battery Life-Cycle Recovery app with you, it can remove the battery warning message and fully recover the projector functionality. Give your device a second life!
