I have successfully bricked a R7800
Little bit of info:
The router originally had the stock firmware but the LAN ports were not working.
I decided to flash OpenWRT and maybe use the device as a wifi client AP
I flashed the latest OpenWRT from the stock web interface and got a boot loop.
I opened the case and connected via serial, and if I held the reset button and interrupted via serial TTY the device entered OpenWRT successfully.
I wanted to restore to the stock firmware (since OpenWRT goes into a bootloop) but since I cannot use TFTP (since the LAN ports do not work) I tried the USB debrick method with a powered USB HUB.
Upon entering u-boot command “usb start” I get this:
(IPQ) # usb start
(Re)start USB...

I could not fix the bootloop so stupidly ran a command that I read on the ddwrt forum which goes like this:
nand erase 0x3480000 0x4480000
Yeah I know I'm an idiot.
As a result now I get a kernel panic when starting OpenWRT.

[ 3.001011] Rebooting in 1 seconds..
The only thing I can do is enter uboot.
It’s a longshot but ive seen on other devices that you can send OpenWRT from a serial console directly. Like on the BT HH5.
cat lede-lantiq-bthomehubv5a_ram-u-boot.asc > /dev/ttyUSB0
And then flash OpenWRT again from a wifi connection.
So basically my question is are there other methods of flashing this router besides TFTP and USB?
Thank you for your time
