Many thanks to everyone who helped

This unit is successfully hashing for 12 hours following firmware upgrade.

Two issues remain

1)
Overnight the "old" issue reappeared , the fans go on FULL PELT , full power
this is the issue that caused me to mess up the firmware in first place:-)
hashes fine continues working but fans seem to go full power mode ! and does
not stop until unit disconnected from power and restarted

i cant imagine this is a fan issue , can it be ? is this not a software/control board issue ?

2)
one of the hash boards has been gubbed for months , is their a Uk repairer ?or
sales place for S9i hash boards ?
are the boards in S9 and s9i the same ?

It's cool to know that it's working again and that you've succeeded with the firmware.

1). Yeah it could be a fan issue, but I'm not sure. Are you running your S9i in good conditions? Is the room big enough?

2). Here's a list of ASIC repair centers: https://www.zeusbtc.com/RepairCenter/

I don't think there are any in the UK, but you could send it to France or Germany perhaps.

However, I don't know if the profitability of an S9i would justify such costs, I don't know if the repair would be justified.

You can always find hashboards on the internet, on ebay for example, but choose your seller extremely carefully if you don't want to receive a dubious hashboard.

No, S9 and S9i boards are not the same, and are not interchangeable.
