Bricked R6400 won't let me interrupt loop from putty
Hi, My R6400 wifi router keeps looping in startup. (It happened after a power cycle from all my gear) Using a CP2102 USB-UART cable and Putty i managed to see what was going on inside the router...
Hi Oliver, thanks for your reply!
I’m familiar with the firmware flashing procedure. Thanks for the link. The problem is I can’t get the device into flashing mode. The LEDs are blinking in a certain sequence corresponding with the boot phase which seems to be infinite and I cannot interrupt (using Putty). Unfortunately i can’t attach a video with the blinking LEDs sequence. Any chance this can be resolved? Or is the device really bricked?
Regards,
Sebastian

You know this because you did everything possible in PuTTY? I'd
expect that to take a _very_ long time.
> [...] I cannot interrupt (using Putty).
"impossible" or "cannot" is not a useful problem description. It
does not say what you did. It does not say what happened when you did
it. As usual, showing actual actions (commands) with their actual
results (error messages, LED indicators, ...) can be more helpful than
vague descriptions or interpretations.
You _might_ actually know what you're doing, but that's not obvious
from your problem description.
- Dear Antinode,
Thank you for your reply!
Probably we’re not speaking the same language here. I’m not a technician that is drilled with problem describing routines. I’m a customer with a broken WiFi router who is trying to get some help because ‘internet how to’s’ are giving no result anymore. These we’re my steps:
1. Power on WiFi router
2. All the LEDs are blinking in a certain sequence and keep doing that till Power Off.
3. Tried reset button in different ways. No changes.
4. Open up the router
5. Connect a USB-UART cable to PC
6. Power On Router
7. Startup Putty with the corresponding com-port and settings. Nothing on the screen
8. Power Off Router
9. Disconnect USB cable
10. Power On Router
11. Connect USB cable
12. Startup Putty
13. See on Putty screen startup sequence Router. (Output Putty in first attachment)
14. On PC tried to interrupt boot sequence with Ctrl-C, Ctrl-insert, special BREAK-command Putty.
Tried this very often and many times in different moments in sequence.
15. Eventually gave up and ask for help in this community where I hope to find some nice people who can give me a good advice.
Thank you.

Sebastian
