Flashing back to BT v5.x firmware - Request for help


'DuDeX' has written to me to request help on his attempt to install BT v5.29.107.12 recovery firmware onto a hub running BT v6.1.x firmware.  Here is an edited copy of his message:

I have been carefully reverse engineering the 5.29 firmware and have got to a point where the 2700hgv with 6.1 firmware will accept the firmware (  However, the only exception now is that as a result of my editing, the digital signature is now void.  I know that there are many people out there who are experts in digital sigs. All I need is someone to sign this file and it will work.  You could always pay Verisign to do this but I assume it costs a bit.

Anyway, I have attached the firmware for you to put it on your site.  Some peeps may be able to get around the signature verification on the router.

Details are as follows:

As I say, all it needs is to be signed and is then good to go!

Editor's note:  Please note that even if the digital signature issue is resolved, there is currently no guarantee that a hacked copy of the BT v5.x firmware will work on a hub previously using BT v6.x.   ie. there is still a very good chance the hub could perhaps be bricked.  Experiment with this modified firmware file at your own risk - it should not successfully install onto a hub in its current state due to the voided digital signature.
