How to unbrick a nüvi - step by step guide

It depends on what bricked your unit, if pc after flashing cure sees your nuvi and you can delete the offending file from your nuvi, formatting is not necessary.
Detete the file causing bricking, then flash original rgn, restart nuvi and see if it works

Create in it a directory named Garmin, restart it and see if you get garmindevice.xml in it (or garmindevice.temp to rename to garmindevice.xml)
If you get garmindevice.xml run Garmin Webupdater.

PS. If you get Garmin logo it can go to preboot mode and use Updater.exe. You have to retry

Edit:
PS.#2 Updater.exe is not Garmin Webupdater. You must read better step by step guide and my post above.

If it doesn't create garmindevice.xml it means NV is corrupt
and if you cant reach preboot and cannot flash kunix's cure and get any error message from Updater.exe,we cant have a confirm of the above statement.
I cant help further sorry.

Cure can't boot as stated in cure thread and in this thread. It is useful only if nuvi cannot be seen in pc and to delete corrupt files.

The Nuvi 150 from my parents went into bootloop. This helped. I was even able to skip the formatting part so they still have their POIs.

Thank you alot.

Hello - trying to unbrick my wife's Nuvi 54. I followed all instructions, downloaded the .gcd file for nuvi40and50_GCD. I run GarminCure3, and it generates a .rgn file. But when I click on "updater.exe", I get an error - can't run and the path name. I am running the program in administrator mode. Any suggestions?

Okay - the .rgn file was generated in a new directory - GarminCure3_TEMP, so I copied that .rgn file up one level into the same directory as updater.exe, and it ran okay. Put Nuvi 54 into pre-boot mode, connected USB, and updater recognized my device. when I clicked okay, got error saying Garmin device is not responding. I re-tried several times, and eventually, got a dialogue box saying no updates available, which implies that my .gcd file may be wrong. I got it from here:
