How to recover the OpenAZBox MOD kernel on an Azbox,
only displaying: Booting...
I ran into problems, after I installed OpenAZBox MOD firmware and wanted to go back to the RTi Core
1.6 firmware.
The problem was that, at the second zboot stage, the box got stuck, due to an incorrect zboot signature.
This problem started when using the latest version of AZUP, at that time 2.2.5.
Connecting my receiver to my PC with a FTDI Chip TTL-232R cable, gave the following error:
Checking zboot signature.. it's not zboot file.
Error : Internal, code = ffffffff

In this tutorial, I'll try to explain how to revive your fooked up AZBox HD receiver. This does not apply to
AZBox Me or miniME receivers.
Please read the tutorial thoroughly, for it describes where to obtain the hardware and also where you
can download additional needed software.
This tutorial is based on my personal situation and I hope others can use it to recover their first genera-
tion AZBox HD receiver. Using the manual or any flashing procedure is done at your own risk.
The manual is based on the original "How to recover a blocked Azbox only displaying:
Booting...".
Special thanks to sattommy for his insights.

Used hardware
I have used a FTDI Chip TTL-232R-5V-WE cable. This is a USB to TTL Serial cable.
Just Google "Yamon cable" and lots of shops will pop up. Please look for a finished product as the image
shows.

Used software
Putty.
Putty is a terminal emulator which also support serial connections.
Since most of us already use Putty we already have it installed.
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Download link: http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
There is no need to install Putty, simply download it somewhere on your PC and launch it.
TFTP server.
You will need a TFTP server on your PC, I use Pumpkin.
http://kin.klever.net/pumpkin/
Download link: http://kin.klever.net/pumpkin/binaries
Possible alternative: http://tftpd32.jounin.net/
Download link: http://tftpd32.jounin.net/tftpd32_download.html (this one has a 64 bits version).
FileZilla
You will need a FTP client:

The YAMON Interface
The connector to access Yamon looks like this on the motherboard:
Connector op de Azbox Connector op de USB/TTL adapter
TX [yellow] RX
VCC DO NOT CONNECT DO NOT CONNECT
GND [black] GND
RX [orange] TX
Just to be clear, I give you the wire colors that I use on the Azbox side since this connector is quite
common and my cable is assembled and ready.
IMPORTANT: On the Azbox motherboard there is a dot near the TX pin, this gives you an
indication on how to connect the cable (see later on for detailed photos).

Recovery of your Azbox.
Just to make sure.
You have the USB to TTL Serial cable.
You have a terminal emulataor [ Putty ]
You have a TFTP server running and pointing on the rigth folder on your PC. [ Pumpkin or TFTP32 ]
You know the COM port number associated with your adapter.
You have connected your Azbox to a wired network, using a network cable (RJ45). Your PC must be on
the same network.
How to find your PC IP address.
To find IP address of your PC, press the Start button on your desktop and type the following in the search
field: cmd
then press the Enter key and a black window will appear.
In this window, type the following command Then type: ipconfig
The result will look like:
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : home
IPv4 Address. . . . . . . . . . . : 192.168.1.7
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

The field Ipv4 Address shows the current IP address of your PC
In this example it is: 192.168.1.7
For your Azbox, you need to find a free IP address in your network in the range of 2 and 253.
Let say we choose 241. In that case, the IP of your AZBox would be; 192.168.1.241
Now, we will test if this address is free:
Give the following command in the black windows, where we typed the ipconfig command, earlier on.
ping 192.168.1.241
If the answer is ....
Pinging 192.168.1.241 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 192.168.1.241:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
... you can keep this value. It seems to be free on your network.

But if the answer is ...
C:\>ping 192.168.1.241

Reply from 192.168.1.241: bytes=32 time=6ms TTL=64

Reply from 192.168.1.241: bytes=32 time=6ms TTL=64
Reply from 192.168.1.241: bytes=32 time=3ms TTL=64
Ping statistics for 192.168.1.241:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 3ms, Maximum = 6ms, Average = 5ms
... you will need to find another IP address , by choosing another random value (between 2 and 253) and
test it again.

Starting Recovery process.
To follow and understand this tutorial you have to keep in mind that, in this example
below:
The IP address of the PC is 192.168.1.7 (by DHCP lease or as static IP number)
The Azbox IP address is 192.168.1.241 (to be defined by yourself)
You will need to adapt the values according to your local LAN. Or you can also
temporarily assign a fixed IP address to your PC. Lets say: 192.168.1.10
Step 1: starting Putty and the serial connection
Power off your Azbox with the back switch and connect the cable carefully inside your Azbox and the
adapter in your PC.
Start Putty.
Proceed, doing the following:
