@emmysammy
You've not answered Point 8, loading Cure3 firmware is what you need to do. Your nuvi 52 is most likely only in a bootloop because it cannot load the voice files copied from the nuvi 55. Go to the [Only registered and activated users can see links. ] to make the cure fw and also read thoroughly the following thread to understand the procedure: [Only registered and activated users can see links. ]. Loading cure fw will re-enable Mass Storage Mode and then you can remove the problem voice files, then load original fw and GarminExpress will offer you the required voice files. Provided that's the problem, there should be no need to re-format the internal memory, only removal of the incompatible VPM files.

@bram1980,

There is enough info here that you need to read:

Start with reading the first post and answer all the question.

[Only registered and activated users can see links. ]

And read what "Butters" posted

[Only registered and activated users can see links. ]

Then try and fix your Nuvi 50LM........

thank you , finally my gps can detect from my computer, but the original firmware said 2.10, after reset just 10 seconds the gps shut down,??

@bram1980,

You did not explain what steps you did.........

from the first post.

Please do so that way everyone has a clear picture of what steps you have taken.......

Use "Garmin Express" to update the firmware and anything else that needs updating or use the "Webupdater" from Garmin..

Spoiler: Garmin Express

OR

Spoiler: Garmin Webupdater

Leave the Garmin 50 on the PC and let it charge the unit up.
If it is a battery problem then look to getting a new battery.

Here is one of many places you can get a battery....

Spoiler: Battery for Garmin Nuvi 30, 40, 40LM, 50, 50LM

There are enough YouTube videos on how to replace the battery if you need to do that.

But make sure you do all the updates to the unit first......

@kaninkalle
Provided there is no hardware fault, there is likely still a file onboard which is preventing the device booting. If you don't wish to go thru further 'trial & error' file removal to find the culprit then simply reformat it using only [Only registered and activated users can see links. ] with correct settings while it has Cure firmware loaded.

About point 7 and the V2.70 firmware file you loaded: I don't quite understand what you've done but if it was placed in the device as GUPDATE.GCD it won't be used to update the device until it next boots fully. In any case, you don't want original fw loaded yet as only cure fw can re-enable Mass Storage Mode in a soft-bricked device by preventing files being loaded during the boot.

About point 9: You clearly can reach preboot as you've loaded a cure fw RGN file.

**kaninkalle** · 19th August 2021, 02:44 PM

Hi Thanks for answering!

point7, as a test i went through the updateprocedure to see if it would accept it, it did and as you said it was there in the storage as GUPDATE.GCD, i thought it might trigger something during bootstart if that file was there, but it didn't.

I went through formating storage ok with the tool(with correct settings) but everything is still the same it dies after Garmin logo, and the fineprint copyright etc, never loads anything more just dies.

Hardwarefault i guess, don't know what else i could try..maybee storagefiles from other gps but i don't know if that would help.

**Butters** · 19th August 2021, 09:41 PM

If you mean that it is still powering itself off even with Cure firmware loaded then it's almost certainly a hardware fault. With cure fw it should just stall on the "Garmin" splash screen but with Mass Storage Mode enabled.

Files from another unit won't help.

**kaninkalle** · 20th August 2021, 01:46 PM

Hi

It don't die in cure-mode, only in "normal" mode.

Normaly after a format of storage, on the next boot, does it rebuild/create the neccesary basic files/folders/settings in storage?
