Having LM maps for North America indicates that it must be HWID 1613 from the factory. Unless you or someone else successfully flashed the complete fw of a different HWID then it remains unchanged. You can check it's HWID in preboot using G7ToWin which is point 7 in initial post of this thread.
Please understand that this device's recent history before the problems occurred isn't clear. I need some answers, like these: Did you buy it in a malfunctioning state? Or was it working ok and then started not recognizing voices etc. without any apparent reason? Or did you try to update it and after a failed update it wouldn't work properly?
This is what you posted in the other thread you started:
You received an answer to the above from the helpful member Garmin_Nuvi directing you to the guide here: [Only registered and activated users can see links. ]. You then posted in this current thread with this information:HI,
i have GPS Nuvi 52. for some reason each time i plug it to my PC it say need to format it. i do so..
but still the same, i cannot access the memory of it..so now i lost all maps
i did install maps on SD card, but the main data have to be in built in memory the ROM.
it dose work, but no voice or other, as all deleted.
any one have idea how to fix?
Much of the information is the same in both posts, some is confusing and unfortunately regardless of numerous posts here by both of us i'm no clearer as to what's likely to have caused the fault. Best start again, firstly by you carefully reading again the document in the initial post of [Only registered and activated users can see links. ], then answer all the questions in the initial post of this thread and state if you don't understand anything about the process in the document by smokefree.i have nuvi 52, suddenly once i connected to PC it say need to format the ROM, and i did. since i can access GPS it self, but no sound or other, i had installed map on SD card and worked.
so i tried the GarminCure3, and now it is totally not working. just boot in garmin logo, tried to rest it it dose not work. i hold lower right nothing happen. i just can keep doing GarminCure3 by cure and original, if cure i can see the ROM, once original nothing happen
also used RMPrepUSB_Portable,. nothing.
This device may be fixable and i won't give up trying to help you but i've run out of guesses and need clear, unambiguous and definite information about how it got 'bricked'. If it's not soft-bricked it may have a hardware fault. That's not so likely but it does happen and sometimes a partial failure of the flash chip can cause similar symptoms as noted in a bricking from faulty files.
