I have downloaded the locked img file for my 1490T and successfully renamed it to gmapprom, unlocked it using the Jetmouse keygen and placed it into the .System folder in the unit. I have also replaced the JCV file with the new one D3084020A and ignored the 3D file as the 1490T cannot handle this. All this now seems to work although I can't easily test out the JCV file from where I am. I am left wondering about the G2S file which is currently D2331040A (from 2011.40) and I think this will not work with 2012.20? Has the new G2S file been released yet? If so could someone please upload it?
