If your SWM8802 Android unit has a faulty software, maybe it’s bricked or lags (and hangs) when you use it then this firmware will help you restore it to factory settings and get it functioning once again.
But note, if you previously modified the system partition in any way, you shouldn’t use this firmware. Unless you REALLY know what you’re doing.
After downloading the firmware below be sure to read the flashing guide thereafter to learn how to flash the firmware.
The file below contains the firmware, flashtool, and required drivers to help you fully setup the flashing environment.
File Name: swm8802 firmware.zip
Size: 510 MB
If you already have SP Flashtool and know how to use it, then this should be easy for you.
Ensure you already have a USB cable connected to your computer before you click DOWNLOAD in the flashtool because you only have about 2-3 seconds to connect your SWM8802.
To learn how to use SP Flashtool please follow this link.
Do not hesitate to ask any questions you might have.
