Here's another way to do this. I am assuming you have a relay switch installed with the cygnos too. Otherwise this wont work.

 

 

Read your 15574 nand on the retail nand with cygnos toolbox

 

Get your cpukey(hopefully you have this saved)

 

Get jrunner application

 

Open your 15574 nand in jrunner

 

Place your cpukey in jrunner

 

Make sure you select  glitch and your 15574 dash(you will need to let jrunner download this)

 

Select create image

 

Flash that image with cygnos toolbox to the cygnos

 

Save a backup of your new 15574 retail nand, cpukey and rgh 15574 you just created for future updates.
