Hi,

I've had this router as replacement en case my main unit failed for some time.

Yesterday I put it to use. After getting everything working I checked to see if there was any firmware update (it came with version 080130). There was so I applied it.

My working speeds worsened noticeably and consistently so I decided to downgrade. The old firmware was also available for download, thus after downloading it I downgraded exactly the same way I upgraded.

Now it doesn't boot. It is not a brick, since the power light is on. It doesn't get out of a very short bootloop. My portable detects a plug and unplug of the ethernet cable continuously.

I would like to know if there is any documented way to recover it, with tftp, or something. Even a JTAG, I could use one but I haven't found any info on this model.

PS I still have to check if it still under warranty, but I'd prefer fixing it rather than having to send it back and wait for it, after all it is a simple and cheap model.
