Need help with SD card for USB damaged 2455LMT, no detailed[and basemap?] map on device too

All i can say is if your device cannot read from/write to the internal memory using SD, that it's imperative you reflow the USB solder so as to regain Mass Storage Mode access and hope it's successful.

Need help with SD card for USB damaged 2455LMT, no detailed[and basemap?] map on device too Hi everyone, I need help prepare all maps(base/details/...) in SD card for my nuvi 2455LMT. Some car cable issue damaged my nuvi 2455LMT, some data lost in device, also usb port partially destroyed. Device can't be recognized neither MTP nor mass storage mode to PC. And my device also lost detailed maps(maybe base maps too) along with all my saved location.My car icon just display on a blank background now. Sadly I didn't back my device before, but I recovered GarminDevice.xml information Rating: 5

Forget to update the post. Finally got it working without any physical repair a year ago.
Not exactly remember the details, but GarminCure3+GarminExpress did the trick basically.

problem: internal drive can't mass storage and can access by LDR.bin in /update/
1. download official 8.3 firmware for Nuvi 24x5
nuvi24x5and25x5_GCDFile__830.gcd

2. download GarminCure3
3. follow "How to unbrick a nüvi.pdf" for how to use GarminCure3
a. makefirmware cure, call update in command line with generated rgn, remember to hold left corner until update complete
4. device can't start, turn off unplug, and open GarminExpress and plug in, and update
5. backup internal storage
6. makefirmware origin
