How to recover a blocked Azbox only displaying:
Booting
If your Azbox is no longer responding and it is stucked with Booting... in the front display, it is normally
possible to recover it but you will need to purchase an adapter cable, USB (RS232) to TTL.
Thanks to andressis2k and VVK to Herbie and to Hectore and to all the other people that contribute to
this solution.
CAUTION: USE AT YOUR OWN RISK, we didn't take any responsibility about
this procedure. It is given as is.
Pre-requisite : hardware needed.
You need a convertor UART TTL to serial/USB, since serial port tend to disappear on PC, I look for an USB
adapter. I find it on eBay:

Seller on eBay Ynhstore8 : http://myworld.befr.ebay.be/ynhstore8/
Object description USB 2.0 to UART TTL Serial Converter w/ Protective Case
Price around 5€
The provided CD-Rom doesn't work on Windows 7, so go to this site to download the latest driver

There is different models available on eBay, I choose one with a case.
