Flashing a mesa 5i25

I bought an unflashed mesa 5i25 and am runing it through a pcie to pci adaptor, I had some problems flashing it and it got disconected whilst running and now has two LED on when powered up, From reading the manual this means I have to reprogram it through the JTAG connector? This is way out of my knowlage base, so is there anyone who can walk me through what cables, software I need and how to do it. or somone in the uk who I can pay to fix it and flash my firmware ot it?
many thanks.

I would probably choose a FTDI based JTAG cable and OpenFPGAloader

Notes:

1. 5I25s cards always have firmware and backup firmware installed, there is no
host card access at all unless firmware is loaded.

2. Simply interrupting a programming operation will not require JTAG recovery
because the user flash image will be detected as corrupted and the fallback image will be loaded in its place.

3. If a programming operation corrupted both the user and fallback images this suggests a hardware issue.
Its best to always verify that you have a stable interface before you attempt to update the on card flash
( Say with a read operation like "sudo mesaflash --device 5i25 --readhmid" )
