Win a Pentax Limited Lens: Raffle Now Live!

I was wondering if those in the know could help me on this.
I thought I had fixed my back focusing problem updating my K10D firmware to 1.31 from 1.30. It is now apparent that I have not fixed the problem

I tried the Vietzon.com Forums link to the hacked file which would allow me to access the debug mode but it looks like it is no more.
Anyone have any suggestions?

As far as I know users cannot downgrade firmware.

The procedure for v1.31 should be the same as v.1.30.

Debug mode
K10D Back focusing Issue

Or use PK_Tether
PK_Tether – Tethering Software for Pentax DSLR Cameras

Is that a k10d thing? I have upgraded then downgraded my k50 without any impact.

Really? I thought it was impossible on any Pentax. Doesn't the software look for installed version and if older upgrades, if same or newer doesn't?
