Revision Content

This article provides tips for resolving common problems you may have while using Firefox OS. Please feel free to add more content to this page!

Note: This instructions assume you have configured the udev settings for your device.

Networking problems

If you are having trouble connecting to Wi-Fi networks, it may be helpful to delete the Wi-Fi configuration file from the device. You can do this as follows:

adb shell rm /data/misc/wifi/wpa_supplicant.conf
adb reboot

Bricked Phone

If you happen to brick the phone, by, for example, trying to flash wrong images on it,  try rebooting into the bootloader (fastboot or heimdal depending on your phone). The exact sequence varies depending on the phone. Try removing the usb cable, removing and then re-inserting the battery. For the Unagi and Otoro, press and hold volume up and power for several seconds until you see the splash screen. Verify that the phone is in bootloader mode by using fastboot devices (or heimdall devices for some Samsung phones). Once you can see your phone using fastboot devices, you can use ./flash.sh to flash your image for Unagi.

Flashing Red LED (otoro/unagi)

This means that the battery is too low to boot the phone. You can let it charge for a while (until the red LED stops flashing and a little bit longer), or you can unplug the USB cable, remove the battery, insert the USB cable, and re-insert the battery.
