ITI nBox 5800sx is dies!!!!

If you played 2850 image from box to box 5800sx unfortunately uboot which is uploaded in August deleted the memory of flesh, now you need to run uboot configuration backup of the address because the current a019 A020 has cleared

I got my box from him..he's a good guy think he charges £30

I myself terz well head equipment repair if someone asked here and it's free

After trying to decypher loads of polish and reading loads of different methods, i tried this and it revived my dead box. thanks :-)

To carry out this procedure you will need to strip down the box completely.
Remove the cover off the nbox, remove the screw holding the tuner in place on the chassis, remove the 4 screws that hold the mainboard in place.
Disconnect the cable from the hard drive (on the drive not the mainboard, i found that easier)
Unplug the grey cable that connects the front panel.

Slide the motherboard back out of the chassis, you dont need to remove the tuner it will all come out as a complete set.
flip over the MB and you will see a wire that has been added connecting 2 points on the board. One end of the wire should be connected 1 pin of a row of 4 pins, the other to a point on the MB which is marked as A20 on the picture shown.
Unsolder the wire from A20.

Now extract the rar file and place all 3 files onto a freshly fat32 formatted usb pendrive.

Place the usb pen into the nbox usb socket.

Now heres the tricky bit, you may find an extra pair of hands useful here!

Connect the grey cable back to the motherboard so you will be able to see what the VFD display says.

Hold the wire you just unsoldered onto point A19 shown on the picture.

Whilst you are holding it get a friend or someone to turn on the power to the box whilst holding in the power button on the front of the box. The display should then say uboot *.**.** (* means numbers of the currently installed uboot) after a second or so the display will say PROG, whilst still holding the power button in take off the wire from A19, it will continue to load back the uboot to the nand. After about 30 seconds it will say OK. You can then turn off the power to the box.

If it says FAIL at any time then you have not got the wire on A19 properly, the box could also be displaying TEST and flashing lights on and off, again this indicates the wire not been on correctly.

If it completes and says OK, then you can now resolder the wire back to A20 and if done correctly the box should boot back up normally, you may have to reselect the correct uboot via the usual method to allow the box to boot whichever image you had on (HDD, NAND etc).

If its all ok, give yourself a pat on the back, reassemble the box and enjoy TV again and crack open a ice cold beer :very-drunk:

It took me a couple of tries to get it to work, i only had my hands!!

Hope this is of help, it took me ages to verify and find the correct files needed.

can you use a usb hdd or does it have to be a usb pen as i dont get anything come up on the display at all hdd spins up fan trys to spin if you move it with your finger it starts to spin cheers

If the front display is dead and it won't boot up, but the hard drive is spinning and the cooling fan try's to turn your uboot is corrupt
