An asciidoc version of the HT802 RCS tutorial.

An asciidoc version of HT802.

== Vonage/Grandstream HT802 Factory Unlock
 
#$$WARNING:$$ This is an advanced topic and will void your warranty! Neither SDF, the authors, contributors or sources linked within this file will be liable for your own actions. Proceed with caution!#
 
#WARNING 2: This page is provided for information only. Under no circumstances should these instructions be used for any illegal purpose or in violation of any contract or user agreement.#
 
Vonage branded models of the Grandstream HT802 come loaded with a factory-locked firmware which does not allow for user configuration. These models will not permit admin login with the standard Grandstream default login of admin/admin. Removing the Vonage settings will require the following tools and abilities:
 
* A philips-head screwdriver
* A computer with a USB port
* A USB-Serial adapter such as a PL2303 or FTDI and male jumper wires
* Terminal software cabaple of interacting with a serial console (screen or minicom)
* Basic hardware hacking knowledge (think raspberry pi GPIO)
* Common sense
* An adventurous spirit
 
=== Step one: Disassembly and mainboard access
 
* Puncture or remove the sticker on the bottom of the device that says "Warranty void if removed". WARNING: This will void your warranty
* Use a philips-head screwdriver to remove the single screw in the center of the bottom of the case
* Carefully unclip and remove the top of the case. The clips are very secure, and may require some gentle force to remove.
* The devices mainboard should now be exposed, you will see the components, including the serial headers labelled below:

=== Step two: Connect to the serial terminal
 
* Using male jumper wires, connect the serial headers on the mainboard to the appropriate pins of your USB to serial adapter: Note: Male jumper wires _should_ slip into the through-holes on the mainboard's header. _Do not_ force anything or you may risk damage to the board.
 
** RX to TX
** TX to RX
** GND to GND
** DO NOT allow the USB to serial adapter's +5v wire to come into contact with the mainboard, as this may cause damage to the device.
 
* Connect the USB to serial adapter to your computer's USB port
* Use a serial terminal program to access they USB serial port, e.g.: 
----
screen /dev/ttyUSB0 115200
----
 
* Carefully plug the HT802 into its power source. If you have everything connected properly, you will see boot messages printed to your terminal window. If you do not see this, disconnect everything and start over, carefully.
 
=== Step three: Apply unlock and flash firmware
 
* Wait for the device to finish boothing. Once it is complete, you should see a root command prompt, indicated by the '#' character.
* Type the following commands, in order. If at any point you recieve an error, stop, and carefully check your work.
+
----
cd /tmp
dd if=/dev/mtd1 of=/tmp/fact-old.img
wget http://shriver.sdf.org/misc/ht802unlock
chmod +x ht802unlock
./ht802unlock
flash_erase /dev/mtd1
cat /tmp/fact-new.img > /dev/mtd1
flash_eraseall /dev/mtd2
----
 
* Note: the ht802unlock file is a small program that reads the file fact-old.img and creates a fact-new.img with the Vonage settings removed.
* At this point you may wish to pause and backup the two files fact-old.img and fact-new.img. Having these will allow you to restore to the factory firmware. You can save these files by doing the following:
 
** First, determin the PID of the web server that the firmware is running, using:
+
----
ps w
----
** Kill the webserver process:
+
----
kill $PID
----
** Start a new webserver in the /tmp directory:
+
----
httpd -h /tmp -p 80
----
** Using a web browser on your computer, access and download the following files:
+
----
http://grandstream_ip_address/fact-old.img
http://grandstream_ip_address/fact-new.img
----       
* Finally, reboot the device:
----
reboot -f
----
 
When your HT802 reboots, you will be able to access the web interface using the device's ip address. The default login admin/admin will allow you to configure the device without factory restrictions.

Sam is a text editor. While the cursor is over the sam window, press the right button of your mouse and drag the cursor over the file name. Release the right mouse button once the cursor is over the file name. The cursor pointer will change to a square. Press the right button, while the square cursor is over the lower panel, to load the file in the lower panel.

A few words about (**w**) writing the file, and how to (**q**) quit "sam". Commands (//sam -d//) are typed in the upper panel, while edits are typed in the lower panel. Press the left mouse button to activate the upper panel, or the lower panel. Type a '**w**' in the upper panel, then press the carriage return. This saves the file. Type a '**q**' in the upper panel, then press the carriage return. This quits "sam".
 
Sam uses it's own cut/paste buffer. Exchange it with Rio's cut/paste buffer by using the <**rio**> option in the middle button (2) menu of sam.
 
The following edit ('% sam -d') will work from the https://wiki.sdf.org/doku.php?id=vps_-$$_$$plan9front_-_acme_sam_abaco_mothra_and_man#sam[VM console] rc prompt, or from the upper sam panel.

== abaco
 
You can use http://lab-fgb.com/abaco/[Abaco] to browse the web^1^. (Abaco is available in a default Plan 9 system.) You'll need to have your IP configured and DNS working in order to browse the web. After that, you'll have to run "webfs" and [underline]#then#^2^ "abaco". If you don't have a "/usr/$user/lib/webcookies" file, _touch_ it once. (You may want to add "webfs" in your "$home/lib/profile" just before plumber and rio.)
 
image::https://wiki.sdf.org/lib/exe/fetch.php?media=plan9-abaco-1.png[alt="plan9-abaco-1",width=600]
 
----
  % touch /usr/$user/lib/webcookies
----
 
----
  % webfs
  % abaco
----
 
When abaco starts, you can go to a webpage by clicking "_New_" with the middle button of the mouse, typing the address in the row below the one with "_Del Snarf Get …_" (see the previous figure: it's the one where the current legacy address is), and pressing "[**Enter**]" on your keyboard. You can follow links by clicking on them, as is usual, with the left button (the shape of the cursor won't change, though).
 
^1^ An http URL. ^2^ Both commands are used on one line with a separator: '% webfs; abaco'. ^3^ Another way to run Abaco.
