Installing Nokia maemo Flasher 3.5 My MacBook Pro runs El Capitan. I am trying to install Nokia's maemo Flasher 3.5, which is an application (or better a command line tool) designed for a 32-bit system (I think it would work on Leopard). If I launch the installer, I end up with a warning (the package is not compatible with my system and may be harmful). Is there a way to get it work?
Metapackage decomposition shows the package was designed specifically for 10.5 and 10.6, no other versions of macOS. Installing the metapackage normally outside of these versions will copy the files to a temporary location but not actually install the software (and also not remove the temporary files, seems like bad design). For more information about the error you received, see Package is incompatible with this version of OS X. If you're sure you still wish to proceed and install this on a recent version of macOS…

The metapackage contains the following packages:


lib.pkg for 10.6, installs a variety of dylibs and other accompanying files
lib-1.pkg for 10.5, similar to lib.pkg
flashergitinstall.pkg for both versions, installs documentation including a readme (included below) and licence documents to /share/doc, and man gz to /share/man.
flasher3-1.pkg for 10.6, installs the binary to /usr/lib
flasher3.pkg for 10.5, similar to flasher3-1.pkg (interesting that the ‘-1’ versions are for opposite versions of macOS to the lib packages)


Excluding flashergitinstall.pkg, the packages only copy files to a temporary location (e.g. /private/tmp/pc-connectivity-bin/10.6/flasher-3.5), then run a ‘postinstall’ to move the files depending on macOS version.

Run the following to install the package:



pkgutil --expand /path/to/flasher-3.5.pkg /path/to/temp
cd /path/to/temp
xattr -rc .
sudo tar xvf ./lib.pkg/Payload -C /usr/lib
sudo tar xvf ./flasher3-1.pkg/Payload -C /usr/lib
sudo chmod +x /usr/lib/flasher-3.5


If you wish to remove the package, delete:


/path/to/temp
/usr/lib/flasher-3.5
the following files from /usr/lib:

.SH EXAMPLE

To flash a image to the Maemo device, open a terminal on your computer, then run:

.B flasher-3.5 -F &lt;FIASCO image&gt; -f -R

Replace  &lt;FIASCO image&gt;  with  the  firmware image you downloaded from Nokia. This will flash a FIASCO image to your Maemo device and reboot device after it’s done (at which point, you can unplug the USB). The procedure is the same for all other image flashing components (like separate kernel, rootfs and eMMC images), see the option list for details. If you wish to do other commands than image flashing, then omit the -R option as rebooting Maemo device may reset given configuration change back to normal.

To flash a kernel image if you have an individual image, open a terminal on your computer, then run:

.B flasher-3.5 -k &lt;kernel zImage&gt; -f -R

If you don't have individual images, but want to flash just a part of the whole FIASCO image you can do so by running:

.B flasher-3.5 -F &lt;FIASCO image&gt; --flash-only=rootfs -R

This will flash just the rootfs from the FIASCO image and reboot the device.

If you need access to the individual parts of the FIASCO image, it can be unpacked by running:

.B flasher-3.5 -F &lt;FIASCO image&gt; -u

Which will expand it to your current directory.

To cold flash (needed usually when the bootloader has been changed) run:

.B flasher-3.5 -c -h RX-51:&lt;hwid&gt; -F &lt;FIASCO image&gt; -S usb

The 'hwid' in the command options is a 4-digit code that can be found from the type label of the device to be flashed.

* 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:
    1. flash Maemo device with Diablo or Fremantle FIASCO image
    2. flash Maemo device (N900 only) internal memory card with eMMC image
    3. unpack FIASCO image into separate parts like kernel and rootfs images
    4. flash unpacked kernel or rootfs images to the Maemo device separately
    5. change Mameo device into R&amp;D mode and back to normal mode
    6. set and clear R&amp;D flags for Maemo device when in R&amp;D mode
    7. boot Maemo device with additional kernel startup parameters 
    8. 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 
      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
   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 set's 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 battery
          runs out of power during image flashing operation and device 
          may not be able to charge empty battery after failure in flashing. 

* TIPS &amp; 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.
