Transit custom dash broken please help

[marvelg]

Hi guys i have corrected the miles or a 2015 custom using the obdprog mt401.
I selected 2013 ford focus, it read the miles ok but i then changed the miles, the dash display then went dark and now is broken.
The cluster has just stopped working altogether and the hazzard lights plus indicators have also stopped.
I know this as a stupid thing to do but i dont mind fixing the issue to gain a bit of knowledge.
Could someone help me with it or explain on how to resolve the issue.
TIA

Start with posting your dump.

Did you tried battery reset?

you used a focus calculation and wrote over important hex strings
put the original back or find a new original dump and i assume no immo data on eprom or it wouldnt run either
