TP-Link Re450 brick after trying to return the original firmware


I use re450 as AP
i installed lede for security in wifi.
After installing Lede, I realized that I only had 64 MB ram, after installation, AP was often restarted.
I tried to return the original firmware, but I got this:

U-Boot 1.1.4 (Jan 11 2017 - 18:09:36)

Autobooting in 1 seconds
## Booting image at 9f020000 ...

then restarts again

Can you fix "AP" it and how?
I apologize for my bad English.


Did You try my "back_to_stock" firmware?

You can write this file to spi flash chip using Uboot commands:
( You must copy this file to root directory on your tftp server (use tftpd32)

tftp 0x81000000 re450_back_to_stock.bin
erase 0x9f020000 +$filesize
cp.b $fileaddr 0x9f020000 $filesize


Translate into the language of your choice...


Thanks for the help.
I fixed my AP RE450.
A small addition to the documentation.
To get into CLI mode I did the following:
When I wrote the "Autobooting message in 1 seconds" I entered "tpl".
After that:
Scorpion> setenv serverip; setenv ipaddr
( - my tftp server, - ip address of my AP)
Then I used the commands above.
