We have two iBox 3. We bought them when they came on the market so they are pretty old now. Booth we had to JTAG and put in a better bootloader and we made a special contact on the motherboards to make it easier to JTAG. We made JTAG working on both Windows XP, Vista and Win7.
It happens that a box crashes sometimes but 100 times a day as KiddaC says seems to be too much. If it does, it is only to restart it again, it always works. If it gets stuck during the boot procedure then it might be a difficult problem, it might be bricked but it does not have to be.
Yesterday when I tried to start an iBox I hadn't used for a long time this happened. No led was on, no boot and no load showed up on the iBox screen. After a while I switch it off and tried again with the same result. I tried to flash a new image from USB with only one usb connection on. It flashed and after restarting it got stuck during boot process. On the led screen I could see BOOT but it never went to Load. It was stuck and the solution was probably to JTAG. But this time I was wrong!
I had a hub with a WiFi stick and a 64 gigabyte USB stick as HDD connected to the USB port on the back. The hub also had its own power supply. It was the same hub I had used before to another iBox3. For some reason, I don't know why, this was a too heavy load for the USB port on this iBox3 and probably lowered the voltage so much that the box could not load the image and stopped during the boot process.
I disconnected the hub and inserted the USB-HDD stick into the USB port on the backside and the WiFi stick on the right side USB port. After restarting it all worked nicely.
Later I connected both the WiFi and the USB memory stick to a new hub connected to the backside USB port. It works. For one of the two iBoxes the old hub was a too heavy load, maybe that box is not reliable any more. It is not only people that get old and weak, it probably goes for STB too.
The reason I started to thread was to know if someone had the knowledge of how to JTAG newer versions of boxes and if it was necessary. Are they safer than the older ones? Of course they should never be switched off during boot procedure but sometime an accident happens. It is the easiest way to brick them. On some boxes (octagon sf8008) they say there is a knob for factory reset, I am still wondering what that is good for and what it does do?
If any else has any experience of the new boxes and what to do if they get bricked, please enlighten me.
Thanks for all good advices!
