- Imagine that you are in Singapore and have a Pie on your device. If you want to upgrade to the latest android version and if the latest version is not supported in your country. Don’t worry. Still, you can flash the latest version, find the right model from the nearest country. Find the right Model number and flash it. (Not recommended but still working).

Download Country/Carrier Based Stock Rom
