Downloads and documentation

Installation

The Flasher-3.5 tool should be installed from the installation package provided for Debian based Linuxes, Windows and Mac OS X. For other than Debian based Linux distributions also compressed tar file is provided.

Installation of Maemo Flasher-3.5 requires administration rights in all supported operating systems.

Short description

The Maemo Flasher-3.5 Tool is a command line utility that supports N900 device with Fremantle 5.x platform releases and N800, N810 and N810 WiMAX devices with Maemo Diablo 4.1.x platform releases.

Notice that older Maemo devices (like Nokia 770) and older Maemo platform releases may require a specific Flasher Tool.

Flasher-3.5 Tool is run from a Linux, Windows or Mac host computer as command line tool, and it will send data and commands to the connected Maemo device over USB.

Flasher-3.5 Tool can be used to:

  • flash Maemo device with Diablo or Fremantle FIASCO image
  • flash Maemo device (N900 only) internal memory card with eMMC image
  • unpack FIASCO image into separate parts like kernel and rootfs images
  • flash unpacked kernel or rootfs images to the Maemo device separately
  • change Mameo device into R&D mode and back to normal mode
  • set and clear R&D flags for Maemo device when in R&D mode
  • boot Maemo device with additional kernel startup parameters
  • and for many other purposes

All command line parameters supported by Flasher-3.5 Tool together with some basic usage examples are documented in Help.txt file available as part of tool installation package. Flasher-3.5 Tool binary gives command line help if it is run without any parameter or with "--set-rd-flags" or "--clear-rd-flags" parameters.

Before flashing Maemo device with FIASCO image it is recommended to set Maemo device first into flashing mode.

For Nokia N800 and N810 with Diablo image, flashing mode can be enabled by following these steps:

  1. Turn off Maemo device (and do not use charger)
  2. Attach USB cable on your Maemo device and computer
  3. Turn on Maemo device while holding down the Home (N800) or Swap (N810) hardware button


For Nokia N900 with Fremantle image, flashing mode can be enabled by following these steps:

  1. Turn off Maemo device
  2. Press and hold down key 'u'
  3. Connect USB cable between Maemo device and host PC while holding down key 'u'
  4. When USB cable gets connected it powers Maemo device and sets it to flashing mode
  5. When USB icon appears on right upper corner Maemo device is in flashing mode
  6. You can release key 'u'


You will see USB image in the upper right hand corner of the screen if you did this correctly.

Maemo device will wait for Flasher-3.5 input indefinitely when it is in flashing mode. If flashing is tried without setting Maemo device first into flashing mode image flashing may fail because Maemo device may not be able to change to the flashing mode automatically.

NOTICE: Make sure that device battery is fully charged before doing any sort of flashing operation because flashing will fail if batteryruns out of power during image flashing operation and device may not be able to charge empty battery after failure in flashing.

Tips & troubleshooting

If you get a "Permission denied" error then make sure you have execution rights to the flasher-3.5 binary executable. You may also need to have administrator permissions or run command with sudo in Linux.

It may help to connect USB cable directly to the computer USB ports, avoiding the use of a hub. The USB ports in the back of a computer may also work better than using those in the front.
