This page is meant as guide for recovery of receivers which is not functioning
due to flash problems.
Important note before you start:
1) The Jtag cable should not be longer than 12". Best to keep it as short as
possible.
2) Before you decide to upgrade your receiver firmware, please do a backup of
your original firmware
3) Your receiver flash rom can be erase and program again and again.
4) Loading the wrong file into your receiver will not damage your flash rom but
only render your
receiver non-functioning. So if you happen to load the wrong
file to your receiver, you can use
Jtag to reprogram it.
5) If Jtag can read your flash rom, then the flash rom is fine. If not, then is
corrupted.
6) It is always safer to use Jtag to upgrade your receiver than to use Null
modem cable.
7) When you use Null Modem cable to load firmware into your receiver, even a
slight error on the
serial port or cable will affect the transfer of file from
your computer to the receiver.
Here is how you build a your own Simple JTAG
Identifying the Chipset (eMetabox III)
1)With the receiver FACING YOU from the front
2) Open the Casing
3) Look inside and on the right-hand side you will see the Card Reader or Cam
slot
On the Left Hand side just next to the Card Reader slightly
lower on the Main Board
You will see a CHIP 1/2 Inch x 3/4 inch approx and see if it
says:-
Hyundai - Korea
HY29LV160 TT - 90V
0109A
THIS IS YOUR FLASH ROM.
4) If this is the CHIP then you can use all the software for 1-2-3 Boxes.
If not, write this number down and keep for future Reference.
5) This way you can state your CHIP number and then maybe it will be easier to
identify
the type of receiver you have and software to use.
