This summary "tutorial" to explain how to fix a DM800 not booting with the code "ERROR01 : NO CA FOUND" on the screen.

Cause of the error:
- bad flash
- official image flashed

-> ERR01 : NO CA FOUND

What doesn't work anymore:
- no boot
- no network connection
- no possible image upgrade
- DreamUp unable to upgrade even with serial cable

Solution:
1) Use DreamUp 1.3.3 with serial (null modem) cable
2) Choose COM1, connect, power ON DM800 and wait
3) After a few seconds the DM800 screen will come back with an IP address
4) Type in that address in IE
5) Flash first a BootLoader (ex: 72R1)6) reboot DM800 and hold power button
7) Wait for IP to appear on DM800 screen
8)Type in that address in IE
9) Flash your desired image

ok nice but when i power on my dm 800 i've this error immediatly (1 or 2second)
so dreamup with rs232 cable don't find my DM.
so it's not very easy to flash it....
have a solution please?

Check the COM port you are using...

If still not possible.
- remove power
- press power button
- put power back
- wait for the screen to show a DHCP given IP address
- try to flash via Network on that address

dammed i've already trying flash by ethernet but when ERR01 : NO CA FOUND appers to screen i can't do anything even if i press power button when DM800 reboot...

Try again. It is the only way to get through it.

- Remove power plug
- Wait 30 sec
- Put power back and immediately hold the power on button

Im having a issue also on my DM800 clone. I tried to flash using the network, but after flashing it try to reboot & after that wont boot.

I have hold down the power button & back on, still same error coming in the front display. no dhcp ip address shows on the front display.

Do i need to flash using the null-modem cable? if so where can i find only the boot loader 1st as you said.

I tried to install Gemini 4.6 , and also how can i find the image is suitable for clone box?


I got to know original box images not support for clone boxes.

pls help.

Many thanks, above method works for my problem.

But i didnt flash only bootloader 1st. after connecting to the serial cable just flash the Gemini image.
