Modify Pocket Loox N100

[starsky74]

Hi,

I wonder if there`s any possibilities to moderate/hack Fujitsu Pocket LOOX N100 which has a Windows CE 5 core. The device has a Samsung 300 MHz processor, and 64 MB internal memory. Navigon 6 is installed and the manufacturer says the device is "locked". So would it be possible to hack this device so that it could be used with f.ex TomTom and TCPMP?

I know this is not a phone/pocket pc, but i pray for help anyways

I have tried to hack it. But without any results. There is no active sync, so you can't hack the registry. I made a dump of the update (1.16.0). I can play play Pacman on my own device ..... :)
I know what I want to change, but I can't build a nieuw image for the moment. I'm working on it, but it is a bit difficult! :mad:

I did it!

But, I can't deploy the picture yet!

:D :D :D

Cool! What did you do, and what are you now able to do? Do you have an image to share?

Any interesting mods for the N100 out yet? How to unlock it is already known, see here: http://www.mediafire.com/?celjlwwzbb1

Hey, it is even a HTC Device...

Especially, any idea how to upgrade the GPS firmware? Using the GPSROUTER command of the boot loader + SirfFlash doesnt work for me, and any of the gps update programs of other WinCE devices dont seem to do the trick either. Im stuck... too bad, from my Loox T830 I already know which firmware I would like to have...

By the way, since some people seem to be still trying:

I did some analysis a while ago on my N100, and I think one main point is that whatever baud rate you set SirfFlash to, it will change to 115.200 in the process. So this is why the GPSROUTER doesn't work I guess.

I was almost (?) as far as being able to at least read the firmware by using this method:

- Find RX and TX lines on the N100 mainboard

- Disconnect them from the system

- Find the TTL level RX and TX lines on a PC mainboard (before the chip that changes the serial voltage +/-12V!)

- connect N100/PC: TX-RX and RX-TX

- connect an oscilloscope to the lines to listen what's up

This is where I found with the oscilloscope that whatever baud rate I set, it seems the SirfFlash always changes to 115.200 after the first initial contact to the chip.

Unfortunately then I was very dumb and destroyed the com port on the used mainboard by creating a short circuit - and that was the end of my trials. The N100 is working Ok, still, after re-connecting the RX and TX lines.

If anyone is interested I might post some pictures about where to find RX and TX on the N100 mainboard later.

Just in case anyone is still trying: Somehow it seems to me that all my experiments to flash update the GPS firmware in the N100 seemed to fail due to baud rate issues. Tracing the serial communication I saw that every time after uploading the data that is supposed to set up the GPS chip to accept the firmware files, the baud rate of the transmissions from the chip side would be at some different value than originally set up. So always the "answers" would not be understood by the PC used for programming. There seems to be no baud rate at which to set up the PC so that the communication works later on. I gave up now, and use the N100 only sporadically anyway...
