Archer A7 V5 [stuck at boot]

[xkpx]

The deal so far was that i managed to flash OpenWRT , and then i forgot the admin password, tried to reset via small button in back but nothing. Then i tried to use TFPT to turn back to StockFm but .... ( turn off the device hold the reset for 10 sec till green is lit and Solaris TFTP confirmed that transfer is complete , then release ) and now
My brand new aracher turned into a brick becouse is keep reseting
Is there a way to fix ?

Try TFTPing the openwrt image again?

I think the image broke it becouse when nothing happend with Stock via TFPT i saw somewhere to use ---squashfs-factory and from that point nothing happens anymore i will record a video

can't read those files ....

but if everything else fails, and the device isn't completely dead, you'll need serial.

I'am sorry i reupload them again https://drive.google.com/drive/folders/1413oj67iS0m4gjGVHuaKq4Mvu6i6_h4M?usp=sharing

CLEAN This is default output without {sending file or anything tftp related , just cable and listening}
TFTP - This is with sended .BIN { router just reboots after the file is sended }

well the router should reboot after the image's sent.
question is what's happening after the reboot.

If you can't get it to accept/write any image, you'll have to get a serial up and running.

I need 4wire jtag right to usb/serial right ? Please suggest some devices

Going back to stock (re200)

get something like this https://www.amazon.com/dp/B07TXVRQ7V/ / https://www.amazon.de/dp/B07TXVRQ7V/ there are cheaper models, if you want to save some $$$. connect it to the PCB, as in the photos in the wiki. remember RX goes to TX, and vice versa. connect GND as well, but not Vcc. fire up Putty using com port assigned to the device by Windows, and hope there's serial output coming from the RE200.

note the comments about the serial port in https://openwrt.org/toh/tp-link/archer_a7_v5#serial

Thanks Sir i will buy the device and try i hope i got my router working again like this.
I'am also pretty sure something messed up in NVRAM becouse its router is stucked with power LED only and rebooting after 1-2 mins. I hope it works <3 if its remember beer is from me.

Btw is it possible using Arduino as TTL device insted of usb ?

Broo miracle small happend for me.
I downloaded factory from here https://downloads.openwrt.org/releases/22.03.0-rc1/targets/ath79/generic/
And then updated via SSH.
Now everything works. Btw i still own you a beer
