[Jerrrrry]

@tr1k0N4 i tried flashing firmware via ttftp and then erased the rootfs partition and tried to write the new firmware in that partition everything went well but somehow the router is now bricked

do you have the fimware of router? maybe i should try with another file one more time

 

[tr1k0N4]

I'd request you to maybe enumerate the steps, please.
