dm800 clone oled display

[jims45]

Hi all...just bought dm800 clone its running perfectly with patched blackhole image.However the oled display does not work, have reflashed the image but no luck.
Would be very grateful if anyone could give advice.

Does it display anything when you first boot up? Like the boot version etc?
There is only one setting for lcd in blackhole afaik. It just says on or off and there is a bar to adjust the brightness/contrast.

open the unit and check the referer board behind the faceplate, theres small plastic contacts there, run your finger along that and try again.

The oled display is not working at any time. Will try cleaning contacts as suggested.Is the display easily replaced if faulty as I not do fancy sending the box back to China!
Thanks for your replies.

Flashing a new firmware (image) by Browser
What you need to flash
You need the image file you want to flash. Image files have the extension *.nfi. You can't flash other
images like *.img files. Don't try it - it won't work.
You need either a DHCP server, a configured bootloader or a serial cable and a terminal program
like HyperTerm.
You need a browser, and a network cable. If you connect the Dreambox directly to the PC,
you need a cross cable, if you connect trough a switch/hub/router you need a normal
(non-cross) cable.
To flash a new image, you can use the second stage loader. It must be present and not broken.
The following steps assume you have a DHCP server. If you don't have one, you have to setup
an IP address in the bootloader's serial setup.
- Power down the Dreambox, either using "shutdown" and by removing the power connector.
Standby is not enough!
- (1.) Press and hold the power button. Replug the power connector into the Dreambox.
- (3.) A text "*** STOP ***" should appear. Now you can release the button.
The bootloader entered the "waiting" mode.
- (4.) Above the "*** STOP ***" text, there should appear an IP-address
(four decimal values with a dot in between). If there appears the string "dhcp" instead,
the box still searches for a DHCP server. Wait a bit. If it doesn't change, something doesn't
work with the DHCP server. Check wether network cable is plugged in etc. If it just doesn't
work, set an IP using the serial terminal)
- Now, open a browser on your PC.
(1.) enter in the address line "http://ip/" (where ip must be replaced with the value in the LCD).

- (2.) on the bottom of the page, there's a link called "firmware upgrade". Click it.
On the next page, you can select the flash image you want to flash. be sure that it has the ".nfi" extension.
You can't flash other images (like .img)!
- Click on "FLASH!" and wait. It might take some time to upload and flash the image.
- Switch the box off again, and on again. The new image should be flashed and working.


======================
Multiboot is almost Barry-Allen there you need an USB-stick for installing
different images !
