=Using the Firmware Updater=
-
It is aparent, like all of the Linkstations, that the firmware does not want to update the firmware if the LS-GL reports the same firmware version as the the one to be that's to be sent to the LS-GL (i.e. a modified firmware).  The work around is to:
+
* <big>[[LS-Pro - Using the Firmware Updater]]</big>
-
*Add to lsupdater.ini
+
-
[SpecialFlags]
+
-
Debug
+
-
*Change in lsupdater.ini
+
-
VersionCheck = 1
+
-
to
+
-
VersionCheck = 0
+
-
*Open linkstation_version.txt in any text editor (i.e. vi).  Edit either the BOOT=, KERNEL=, INITRD=, or ROOTFS= (this is the main firmware and filesystem) to choose what to update by changing the version to a higher number.
+
-
**i.e. by setting rootfs to a higher number, the filesystem will get updated, but uboot, kernel, and initrd won't get updated.
+
-
* Steps originally drafted by Georg.
+
-
'''Note:''' We are not positive if only one segmet (i.e. rootfs) will get updated. This method must be fully tested to find this out.
+

* As EricC documented on the LS-GL side clientUtil_server handles the update process and replies to various "ACP"-Commands, which are similar for the LS-GL and the Kurobox:

+
-
:8080 ACP_FIRMUP2
+
-
:80A0 ACP_??  Possible Password?
+
-
:8A10 ACP_CMD
+
-
:8B10 ACP_??  Sent after 8080 and contains the filename. TCP File transfer starts after reply

=Telnet Access=
+
-
We have successfully managed to create a telnet-enabled firmware for the LS-GL.  Fortunately for us, the LS-GL already came with a telnet binary in the stock firmware.  Telnet can be enabled by uncommenting line 42 in /etc/init.d/rcS and repackaging hddrootfs.
+
-
 
+
-
There is a pre-made telnet enabled firmware available at [http://downloads.linkstationwiki.net/arm9-LS_Pro/telnet_enabled_no_root_password/LSPro-103.zip here].
+
-
 
+
-
'''Note:''' The above firmware package does not enable root access.  For users that already have root access, this firmware is fine.  There is testing being done for a telnet enabled firmware that includes root access.  See [http://linkstationwiki.net/index.php?title=LS-GL_Custom_Firmware_Development#Heinz.27_Method below].  Also, for repackaging the firmware, see [[Create_a_custom_firmware_image]].  The current firmware password is:
+

+
-
 
+
-
=Removing Root Password=
+
-
We are currently working on removing the Melco root password in the stock firmware.  Some users have managed to do this, but the development team as a whole has not agreed to which method to use.
+
-
===Manual Method===
+
-
The general idea is to open connect the sata drive to a desktop running a linux distribution (i.e. Knoppix or Ubuntu).  Then remove root password in /etc/shadow.
+
-
 
+
-
 
+
-
====Detailed Steps====
+
-
1) Connect the hard drive to a pc running Linux (i.e. Knoppix boots directly from cd/dvd)
+
-
 
+
-
2) Find out how it was recognized. (i.e. in Knoppix there are some shortcuts on the desktop).
+
-
 
+
-
3) Open a shell/commandline/terminal.
+
-
 
+
-
4) Mount the second partition of the sata hdd to somewhere.
+
-
 
+
-
5) Delete everything on the partition
+
-
 
+
-
6) Download the telnet enabled hddrootfs.img located in this [http://downloads.linkstationwiki.net/arm9-LS_Pro/telnet_enabled_no_root_password/LS-GL-103.zip zip]
+
-
 
+
-
7) Unzip hddrootfs.img...you will be prompted for a password.
+
-
it is:
+
-
IeY8omJwGlGkIbJm2FH_MV4fLsXE8ieu0gNYwE6Ty
+
-
 
+
-
8) Untar the resulting file to the second partition:
+
-
tar xzvf <file> <path_where_you_mounted_the_first_partition>
+
-
 
+
-
9*) mount /dev/sda1 (assuming the sata drive is the first special drive connected on the pc) somewhere
+
-
*extract conf_saved.tgz, remove password in etc/shadow to look like:
+
-
root::11009:0:99999:7:::
+
-
 
+
-
10*) re-tar the contents of conf_saved.tgz, replace conf_saved.tgz to /dev/sda1,
+
-
umount
+
-
 
+
-
 
+
-
(*)These steps still need to be tested further!!!
+
-
*Steps originally drafted by mindbender.
+

+

===Heinz' Method===
+
-
Heinz made a script to automatically convert a downloaded stock firmware into a telnet enabled firmware with root access.  The script is made for the German firmware.  The script is available [http://downloads.linkstationwiki.net/arm9-LS_Pro/telnet_enabled_no_root_password/enable-telnet.sh here].  Heinz also made a pre-made firmware package with his script.  It can be downloaded [http://downloads.linkstationwiki.net/arm9-LS_Pro/telnet_enabled_no_root_password/LS-GL_FW_103-modified.zip here].
+
-
*'''Testing Needed'''
+
-
 
+
-
The script mainly does the following things:
+
-
 
+
-
* retrieving the actual firmware update from the buffalo site.
+
-
* unzip the archive to a tmp directory
+
-
* modify linkstation_version, because the updater only updates "newer" firmwares. It seems this can be overwritten in the debug mode (see georg's changes)
+
-
* for modifing the installed image. it is unzipped (using the current password)
+
-
* then to start the (already installed) telnetd, some comments in the rcS script are removed.
+
-
* because the password of the root login is not known, it needs to be removed. Modifing /etc/shadow had not worked, so currently we change the web interface, which runs with root permissions, to do it for us.
+
-
* reverse the whole zip/tar process to create a useable firmware update again.
+
-

+
-
===Georg's Method===

-
Georg modified Heinz' automatic script.  For those with access, the script it is available in [http://downloads.linkstationwiki.net/uploads/LS_Pro_temporary/telnet_enabled_no_root_password/ LS_Pro Temporary Upload Folder for Telnet Enabled Firmwares]

LS-GL Custom Firmware Development
This wiki page is to document the work and progress in developing a custom firmware for the LS Pro (LS-GL) The goal of this page is to sort out the roadmap and accomplishments towards creating an OpenLink and FreeLink for the LS-GL. Though this page is mainly for developers, anyone is free to add their work.

 
WARNING!

The methods and information described below are intended for advanced users. Much of the information has not been verified by the development team. As a result, all users must exercise caution when performing any of the described methods. Failure to do so may result in a bricked Linkstation.


Please fix and update these sections. Also, please correct any grammar and spelling errors. Thanks --- Jonli447
