What is Firmware over the air (FOTA)?
Firmware over the air or FOTA is a convenient way of updating the system software of your android phone. It doesn’t require the device to be plugged into a computer to perform the update. It also allows the phone to retain user information like contacts, calendar, emails, text messages and more.
How does FOTA work?
The HTC Desire HD routinely checks for software updates. When a software update is available, the phone notifies the user that a new software update is available and prompts the user to download the update file to the phone. Once the user has downloaded the update file, which gets stored into the memory card, the device prompts the user to install the update. After the installation is complete the phone reboots and the device is updated.
What happens if the downloading breaks in the middle?
The download manager is capable of resuming a download. If the downloading is interrupted because of data connection loss, or the user turns off the device, the download will resume as soon as the next data connection comes back.
What happens if the installation breaks in the middle?
The FOTA installation is performed in the Recovery mode; there is no way for users to interrupt the process unless the device runs out of battery. In such cases the device can still reboot into Recovery mode and restart or resume the installation when the battery is back.
What is the FOTA behavior in roaming mode?
In roaming mode if the data connection is through 3G/GPRS, all check-ins and downloads will be blocked. If Wi-Fi connection is available then the checking and downloading can still work.
