Thread: How to patch unlock garmin img

I have spent hours and hours searching for a tool to unlock locked .img files. There is tons of rubbish out there, but this method is brilliant and works as advertised! Thanks a million for your generosity in sharing this.
As an aside, I purchased 4 second hand maps from secondhandgpsmaps.com despite being very suspicious about them. It seems my suspicions were warranted as they only delivered two of the four maps I paid for. The maps are all locked. They have not responded to my email enquiries about the missing maps or given me an indication on how to unlock the maps. So beware!
But your method here has solved the problem nicely. Thanks again.
