1. Shortcut the 2 pins with the label R148 next to the screen on the EB according to this [picture](https://wiki.openwrt.org/_media/media/arcadyan/eb904xdsl_pcb_r148_uart.jpg?w=500&tok=318f3d) for example by soldering two wires to the pins and simply connect them while starting, or use a tweezer etc.
2. Connect you serial console according to this [picture](https://github.com/majuss/easybox904/blob/master/serial.JPG?raw=true) and connect the USB to your computer.

3. Start screen on your Debian with the command `screen /dev/ttyUSB0 115200`
4. Now start the EB while you shortcut the pins. After it started you don't have to shortcut anymore.

8. Now hit enter when it asks for a password. You will now see a prompt like: `VR9 #` enter `loady`. A program will start which allows the recieving of a new u-boot via y-modem.
9. Transfer the closed u-boot image with: `sb uboot_closed.lq </dev/ttyUSB0 >/dev/ttyUSB0`.
10. Switch to the screen-window, when the transferring is finished, loady will close automatically. Erase the partition of the persistent memory which contains the bootloader: `nand erase 0 d0000` and write the transferred file with: `nand write 80800000 0 40000`. Note that the "80800000" is the memory address where loady saved it's recieved data, you see this address when you start loady or when the transfer is finished.
11. Turn off the box, hold the reset button, and start it. Hold the button for about 10 seconds. Now prepare the tftp-server and serve the opened-firmware image (see the quick and easy guide). When flashing is finished your EB is debricked.
