Serial Interface to connect to AZBox HD
You also need your PC's IP address (via command prompt):
Start -> Run -> write: cmd -> hit enter on your keyboard -> ipconfig -> enter -> your PC's IP address is there
If your PC IP address = 192.168.1.12
We choose AZbox HD IP address, let's say 192.168.1.34
1. Start TFTPD32
2. Start Putty, choose serial, put the COM port where your serial interface is, Speed = 115200
3. Connect serial interface with AZBox and switch AZBox ON
4. Press CTRL+C to stop the booting
setxenv y.ipaddr 192.168.1.3
setxenv y.gateway 192.168.1.1
setxenv y.subnetmask 255.255.255.0
load -b tftp://192.168.1.2/backup_kernel 0xb0100000
pflash write -f 0x80000 0xb0100000 0x680000
Wait till it erases a part of the FLASH, then write the new content in.
This lasts around 5-6minuts, be patient and when it finishes - reboot your AZBox.
If it went well, on your TV screen you will see a standard update you came to know so well...
Plug a USB stick with Official FW and proceed as usual.
I did it all like this, connecting AZbox with PC via rs 232 and LAN connection.
Home-made but works:
