--- Quote from: Merlin201314 on November 16, 2016, 05:34:01 PM ---The splash is resident in the bootloader!!! I deleted all the files in the nand1/nand2 and the main root, the controller is bricked and it turn on with a persistent splash screen(the original one), nothing more..DEAD!! Now i am going to try to reload the files from the usb and see what happens :palm: :lol: Good luck Emanuel --- End quote --- That's expected to happen. Changing the bootlogo is also possible by altering the command line that is passed to the kernel by the bootloader. If we knew how the bootloader was called, we could try finding a way in through it. Just install the full firmware upgrade and everything should work again. After that, just reinstall the latest mod to get the custom splash screen back. |

Just done, all good as before :med: The OMIO cnc clearly bought the entire firmware, as they have their own logo on the machines with the same controller the question is: where they got the boot loader from? |

Or the company who made these did that. It is absolutely trivial to do so, as soon as we have more info on how the controller's bootloader works and which one it is (uboot - probably not, blob, etc.) |

The Digital Dream has shutted down, they no longer exist, maybe someone else took over the project |
| Merlin201314:
My question is: If without firmware in the nand the bootLogo still working, that mean the image is embedded inside the bootloader no? Am i wrong? SO, how they uploaded the Bootloader into the ROM? by the second usb port? Or they can connect the controller via a debug interface? Be an ignorant like me is very frustrating :palm: (some times) |
