Hi,
I think I Kill my router's hardware (Archer C50) because by removing the flash chip to re-record your FW, some of the motherboard's trails have been damaged.
My hope is to find a socket and use wired solder to connect the flash chip to motherboard.
If someone knows if another solution or indicate a tutorial on the subject would be of great help.
If you were already familiar with electronics you would know how to and if it is worth the effort and your chances of getting it fixed.
Otherwise IMHO don't waste time. If I'am wrong I am happy to see your howto :- )
Your provided information is also to sparse & vague. But perhaps you are lucky and someone provide better help than me ;- ) Anyway: Good luck!
