Hello, After I installed OpenWRT 19.07.02 on TP Link Archer C50 V4 I experienced the common 2.4 GHz Wifi range issue so I decided to revert to stock firmware.
I tried flashing the stock image through web interface and TFTP directly and it bricked the router (Only Power or Power + Lock led on).
I have also tried stripping the first 512 bytes before flashing it and it didn't work either.
He suggested inserting 0x30000 dummy bytes at offset 0 and removing the last 0x30000 bytes at the end of the file but I don't know how to do that using dd commands.
If you could transform these to dd commands I would be so much thankful.
