It's ok, no need to be sorry. I'm sure your English is much better than my Bahasa, Javanese or Malay .

In that case we should delete the latest detail map from the internal memory, look for "gmapprom.img" and any other similarly named files like "gmapprom.unl" and "gmapprom.gma". Remove them from the device but first make sure you have copies of them in your backup. Then open the folder from my previous PM named "Original" and follow the steps to flash that RGN in preboot.

It will now boot fully if those map files were the cause and you can just connect to GarminExpress to replace them with healthy ones.

If it 'bricks' again contact me again by Private Message with a link for an upload of a zipped files backup, so i can check all other files for you. It'll be a large file so use MegaNZ for that please.
