2 things are important for success:

1 Before doing anything Drag&Drop the rgn file you want to flash to your device in Updater.exe and it will open in your desktop.
2 The appropriate .rgn file must be in the same directory as the updater.exe.

Normal because you loaded cure.

I previously formatted the nuvi with RMPrepUSB with these settings: Max/GARMIN/Set part as non bootable/MS DOS Bootable/Boot as FDD/Fat 32.

Correct

I've made multiple attempts at holding the power button while simultaneously pressing the upper left corner of the screen and plugging in the USB cable (it would be easier if I had a third hand). But it seems like the nuvi is not recognizing the pre-boot attempts.

Have you dragged original .rgn in updater.exe ? Try this: shutdown Nuvi, attach it USB, it will start by itself and you wont have to press ON button, but just immediately before it starts hold on your finger on upper left corner.
If you loaded the .rgn in Updater and ticked USB ,you'll get for some seconds you nuvi model in Updater, this is the moment to hit ok.
Try and retry, this is the only way to revive your nuvi.

On nuvi 2x5 if i remember corect you must lock screen+finger or hold power button+finger and when you see logo then release power button but still hold screen.

Open nuvi and look if you add power button correct back, you will see on button little space where must be button from switch ( marked on picture with red circle ).

Kunix invented it so he would better explain, but in brief Cure3 is a 'stripped-down' fw which does not load map image files, voice files etc. This allows you to access the internal file system to reformat or to delete any corrupt file/s which cannot be loaded and therefore are preventing the unit from booting. The cure fw cannot boot the unit, merely allows it to be accessed for that purpose. The original full fw must then be loaded in pre-boot to complete that process and finally fresh necessary files are added.

Loly's question is valid, the method you used to access pre-boot for loading the cure should still work after it's been loaded.
