HTC just posted the RUU file so that users can now manually install Lollipop on the Sprint One M7. If yesterday we told you that the Sprint’s One M8 will be getting its update next week, now we can let you know that the Sprint M7 is also getting the Lollipop treatment. If you don’t have access to a Wi Fi network, you can manually install the update via manual download.
You will have to download the 1.5 GB file to your PC and be sure the device is detected when you plug it in. Then you will have to install HTC Sync Manager where you will find the necessary drivers. Then you just launch the file and it will show an installation wizard. This action is completely re-flashing your phone, which means it is likely that everything will be deleted. Be sure to back up your files before manually updating.
