Use openwrt to access the router boot loader

Hi,

Can I use openwrt to access my router's boot loader, so I can reflash it? (through the wan port)??

 

Thx in advance

If you are able to boot

If you are able to boot openwrt then your bootloader works and there is not need to reflash it. If you cannot boot any firmware then you can only reflash the bootloader through JTAG.

You can reflush bootloader

You can reflush bootloader only through JTAG cable. Why are you interested to flush out the bootloader?

I think the bootloader/backup

I think the bootloader/backup loader is messed up. Because I flashed ddwrt, stock, and openwrt with the backup loader and openwrt is the only one that worked. The others just killed my router. (My computer wont recognize them).

This rather sounds like the

This rather sounds like the builds you used were broken.
If there is anything with the bootloader then you cannot boot any firmware.

To break the bootloader you would have to manually overwrite it, a web firmware upgrade never writes to the bootloader partition and cannot break it.

hmmm...

I tried two versions of the stock firmware and one ddwrt. So i really doubt it's the firmwares' problem. Interesting...
