As I haven't posted here for nearly a month, I will now quote an email I got by a guy I contacted. All copyrights go to him, I haven't had time to test his explanations, but maybe it helps some of you that want their A910 to connect to every wireless network._

I'll try to make some explainations. We can discuss together in order to improve the text and make a correct howto we can put on the web… (contains and form (I'm an old vi dinosaur from 1994 ;) ) + the english, as it's not my mother language…) 4 parts: telnetd, swap, wifi and mackconnectivitypack/fake_dsm
  1. Telnetd/login Motorola didn't install any telnetd nor login. (thanks, Moto :-) Mount your phone as an usb mass storage, then edit [path]/.system/javaCardRegistr
    y and set lines as follow (you can install a dummy java application then adapt the values (IMEI, AppID,…) JavaId must be -1.
[1bf504e3-a1e3-d1e8-b96a-40f3a7f60087]
AppID = {1bf504e3-a1e3-d1e8-b96a-40f3a7f60087}
Args =
Attribute = 2
BigIcon = inetd.png
Daemon = 0
Directory = /mmc/mmca1/scripts
Eraseable = 1
Exec = inetd_start.lin
FixedAllPosition = 0
FixedPosition = 0
GroupID = ezx
IMEI = 353300010213731
Icon = inetd.png
InstalledDate = 2007/6/6
JavaId = -1
LockValue = 0
MassStorageStatus = 1
MpkgFile =
Name = Inetd_Start.lin
OsVersion = 1.0
Shared = 1
Size = 64K
Type = 2
UserID = ezx
Visible = 1

with /mmc/mmca1/scripts/inetd_start.lin

#!/bin/bash
export QTDIR=/usr/lib/ezx
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/ezxlocal/sbin
export PATH=$PATH:/ezxlocal/sbin
my_alert='/usr/SYSqtapp/phone/alertprocess'
my_mid1='/ezxlocal/sbin/done.mid'
cp -f /mmc/mmca1/sbin/inetd.conf /tmp/inetd.conf
echo -n “Starting internet superserver:”
echo -n ” inetd” ; start-stop-daemon —start —quiet —chuid root
—pidfile /var/run/inetd.pid —exec /mmc/mmca1/sbin/inetd
$my_alert -playvol 1 -playfile $my_mid1

/mmc/mmca1/sbin/inetd.conf contains:

telnet  stream  tcp     nowait  root    /mmc/mmca1/sbin/in.telnetd
in.telnetd -L /mmc/mmca1/sbin/login

for the in.telnetd daemon, login exec, those from my A780 are ok, or google search Telnet_Samba_preload.rar on a russian moto site. A780-AddOns.tgz is also very usefull for login and many more (was available on the old motorolafan download section, but no more today) (install without diska sub-directory, into your mmc card)

Then after a A910 reboot, you see into games, a “Inetd_Start.lin” you can activate (hear a sound).

you can connect your linux box (A910 usb in modem mode)

usb 4-2: new full speed USB device using uhci_hcd and address 4
cdc_acm 4-2:1.0: ttyACM0: USB ACM device
usb 4-2: USB disconnect, address 4
usb 4-2: new full speed USB device using uhci_hcd and address 5

see http://www.courville.org/mediawiki/index.php/EZX

echo “AT+mode=13” > /dev/ttyACM0
echo “AT+mode=99” > /dev/ttyACM0

sometimes more than one time (why? :-), until you get something like this in the kernel message (dmesg):

MontaVista(R) Linux(R) Consumer Electronics Edition 3.1
Linux/armv5tel 2.4.20_mvlcee31-mainstone_pxa27x

(none) login: root

MontaVista(R) Linux(R) Consumer Electronics Edition 3.1

No directory /root!
Logging in with home = “/”.

I set a more convenient environment with

/mmc/mmca1/root/start

root@a910 ~ 11:38:16 > cat /mmc/mmca1/root/start
#!/bin/sh
/etc/init.d/ezxenvr.sh
export PATH=$PATH:/mmc/mmca1/.system/bin:/mmc/mmca1/.system/sbin
export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$QTDIR/lib:/lib:/usr/lib:/usr/lib/ezx/lib:/mmc/mmca1/.system/lib
export EZX_RES_FONT_PATH=/usr/lib/ezx/lib/fonts
eval “`dircolors -b`”
alias ls='ls —color=auto'
export HOME=/mmc/mmca1/root
cd $HOME
export COLUMNS=150
/mmc/mmca1/.system/bin/bash

root@a910 ~ 11:38:22 > cat .bashrc
export PROMPT_COMMAND='echo -ne “33]0;root@910:${PWD/#$HOME/~}07”'
export PS1=”u@a910 w t > “
export HISTFILESIZE=100
export HISTSIZE=100
export HISTCONTROL=ignoreboth
export QTDIR=/usr/lib/ezx
export EZX_RES_FONT_PATH=/usr/lib/ezx/lib/fonts
eval “`dircolors -b`”
alias ls='ls —color=auto'
export HOME=/mmc/mmca1/root
export COLUMNS=150
. /etc/init.d/ezxenvr.sh
export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$QTDIR/lib:/lib:/usr/lib:/usr/lib/ezx/lib:/mmc/mmca1/.system/lib
alias scp='scp -S /mmc/mmca1/.system/bin/ssh -q'
alias sftp='sftp -S /mmc/mmca1/.system/bin/ssh'
alias l='ls -l'
alias ..='cd ..'
alias cp='cp -v'
alias la='ls -la'
alias ll='ls -lA'

Then, I changed the telnetd and login directory, moving from /mmc/mmca1 to /ezxlocal (11Mb internal A910 storage) so telnetd is no more dependant of the removable microSD.

  1. swapspace I also set a swap space ( no more available on motorolafan) in /mmc/mmca1/.system/java/CardRegistry:
[793bffb3-96f9-d929-bfd7-84e623c514cf]
AniIcon =
AppID = {793bffb3-96f9-d929-bfd7-84e623c514cf}
Args =
Attribute = 4
BigIcon = swapon.png
Daemon = 0
Directory = /mmc/mmca1/.system/swap
Eraseable = 1
Exec = swapon.lin
FixedAllPosition = 0
FixedPosition = 0
GroupID = ezx
IMEI = 35330001*******
Icon = swapon.png
InstalledDate = 2007/6/13
JavaId = -1
MassStorageStatus = 0
MpkgFile =
Name = Swap_on_off.lin
OsVersion = 1.1
Shared = 2
Size = 386K
Type = 2
UserID = ezx
Visible = 1

root@a910 ~ 12:14:25 > cat /mmc/mmca1/.system/swap/swaponoff.sh

#!/bin/sh
SWAPDIR=/mmc/mmca1/.system/swap
SWAPFILE=$SWAPDIR/swapfile
if [ ! -f $SWAPFILE ]; then
     gzip -c -d  $SWAPFILE
fi
if ! grep $SWAPFILE /proc/swaps; then
     swapon $SWAPFILE
     rm $SWAPDIR/OFF
     touch $SWAPDIR/ON
     my_mid1='/usr/data_resource/ringtone/rt_alert_2.mid'
else
     rm $SWAPDIR/ON
     swapoff $SWAPFILE
     touch $SWAPDIR/OFF
     my_mid1='/usr/data_resource/ringtone/rt_alert_5.mid'
fi
my_alert='/usr/SYSqtapp/phone/alertprocess'
$my_alert -playvol 1 -playfile $my_mid1
  1. Wifi The WIFI connection tool /usr/SYSqtapp/wsp/wlanapp fails everytime (UMA stuff? Orange or BT limitation? Grrr…) so the solution is to kill the process when we are connected and continue with normal dhcp request: see the awful script setwifidhcp.lin:
#!/bin/sh
/etc/init.d/ezxenvr.sh
export PATH=$PATH:/mmc/mmca1/.system/bin:/mmc/mmca1/.system/sbin
export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$QTDIR/lib:/lib:/usr/lib:/usr/lib/ezx/lib:/mmc/mmca1/.system/lib
export EZX_RES_FONT_PATH=/usr/lib/ezx/lib/fonts
/usr/SYSqtapp/wsp/wlanapp >/ezxlocal/wlanapp.log 2>&1 &
pid=`find /proc/ -name exe -ls 2> /dev/null|grep wlanapp|cut -d/ -f3`
connected=0
while [ ${connected} -eq 0 ]; do
     sleep 2
     connected=`grep “Successfully connected to AP”
/ezxlocal/wlanapp.log |wc -l`
done
kill $pid
kill `cat /ram/tmp/dhcpcd-eth0.pid`
rm /ram/tmp/dhcpcd-eth0.pid
dhcpcd eth0
my_alert='/usr/SYSqtapp/phone/alertprocess'
my_mid1='/ezxlocal/sbin/done.mid'
$my_alert -playvol 1 -playfile $my_mid1

Now, the problem is the setting of the dnsproxy process:

cat /etc/dnsproxy.conf
include /ram/tmp/dsmdns.conf
include /ram/tmp/pppdns.conf

Even when I fix a proper value into /ram/tmp/dsmdns.conf, it's not taken into account. By mounting a writable /etc, I can set a working /etc/resolv.conf http://www.courville.org/mediawiki/index.php/EZX#Make_.2Fetc_editable_.26_change_root_passwd_.28more_secure_telnet.29

  1. mackconnectivitypack/fake_dsm

When the wifi link is ok (see iwconfig eth0) I can access internet with native application (ping, telnet,…) but not with web browser, nor native opera nor java opera-mini.

The solution would be to set a fake_dsm route but I did'nt succeed… I used the dsm_spy from clovisKKK to adapt the fake_dsm code, as suggested in the thread http://www.motorolafans.com/forums/viewtopic.php?t=9096&postdays=0&postorder=asc&start=0

B******

As you can easily see, there is still a lot of work to do, and I have to say, I'd prefer to modify the firmware and flash it into the device to get things working without lots of dirty hacks not everybody is able to perform.

With hindsight (May 2021):

Back then this wasn't as helpful for me as you would maybe think, as I did not know how to successfully exit Vi yet.
