Yes I used RMPrepUSB, following the setting in the "unbrick step by step guide." It looks like have been completed successfully. Right after formatting I think I saw only one folder called something like "formatted drive... ". Then after Garmin Express software refresh (I only got through halfway stopping at the restart), I think I saw 4-5 folders.

No I don't have Mass Storage Mode anymore at this moment. I had Mass Storage Mode after the formatting, but now I can't even get the device to connect to PC or boot up. Every time I connect the USB, only a dimmed Garmin logo showed up for 2 sec, then the screen went to black, which really sucks. I don't know what else I can do at this stage. It won't boot when I long-press the power button, so I can't even try the preboot trick (it feels super hard to do anyway).

BTW, is there anyway to completely drain the battery without opening the case? I found it need torx-5 screwdriver which I don't have.
