I noticed the first link on the first page of this thread (Damipan) the china .img file is locked. I also had downloaded the unlocked version of the china .img file (megaload). Just for interests sake, I was trying to use the garmin unlocker and gmaptool to unlock the locked china .img from the first link. I did the procedure using these tools as I had done before and a new unlocked .img file was created but I don't believe it is correct when I compare it with the premade unlocked version from the megaload link.
I think it has to do with all the extra srt.img files. Are these files the offset correction? When I examine the Megaload unlocked .img file in GMaptool, the srt.img files seem to be linked with a corresponding map .img file. But when do the unlocking and joining on the locked version and examine the new file in GMaptool, the srt.img files do not seem to be linked with the other map .img files so I am assuming that the offset correction will not be there.
Can someone give a detailed procedure on how the unlocked china .img file was created while still maintaing the offset corrections?
