We use N810s to do on-device testing of our maemo4 builds of our mobile browser. In order to deal with maintaining 80 of these devices we have developed an imaging solution. Our initial attempt was to create a custom firmware image but file corruption became an issue. We eventually figured out how to boot these devices from MiniSD cards. We have special tools for creating and maintaining the filesystems on these cards. | We use N810s to do on-device testing of our maemo4 builds of our mobile browser.

The purpose of this step is to zero out the root mtd device as well as reflashing the linux kernel and bootloader. We want to make sure that any possible corruption in these critical subsystems is repaired | The purpose of this step is to zero out the root mtd device as well as reflashing the linux kernel and bootloader.

this is a sign that moz-prep encountered an error. This is a sign that for some reason, the nokia flashing program lost connection to the device. This is often caused by trying to flash with a dead battery. We mitigate this by flashing with the charger connected. This has also been caused by issues with the linux kernel on the imaging host. If you encounter this error on multiple devices using different batteries reboot the imaging machine. If you still have issues, someone has broken the imaging machine. | this is a sign that moz-prep encountered an error.
