My router has been bricked for 6 months, or more.. week by week I fought with it. Finally I've managed to get into the uboot console, after months of having no boot wait. (I solved that by using a non-usb serial cable)
Can you explain how you solved that in a bit more detail?
from reading it - it sounds like his USB-UART converter would not work fast enough to catch the bootwait. Changing to a real UART allowed him to get it back.
Is there a specific key that I would need to press in order to catch the boot wait, if I do not see it?
Here is my current terminal output

I recovered from this using the SerialComm updater with a WinXP machine.
1. Download and install the SerialComm utility
2. Download the full_image from this post
3. (optional)Connect serial console to router and boot up router
4. Connect a LAN cable directly between router and Laptop (no intermediate HW)
5. Start the SerialComm utility and point it to your wired LAN connection used in step 4
6. Point SerialComm to the full_image.bin you downloaded in step 2
7. Ignore the warning about "older version". If your router was running a new firmware before bricking, flashing the full_image from that posts will "downgrade" it to revision .17
8. Hit the "flash" button in SerialComm and get some coffee
9. AFTER a successfull flash, you may need to power cycle the router
Cheers and thanks for all the help!
