Firmware install help.

Post by Bklyn3 »

Hello,

I accidentally deleted the firmware on my Zumo595.
The unit is no longer recognized by my Mac, not even as a HD.
I did all the reset suggested by Garmin (5sec + bottom right corner of the screen etc…) and off course check different Cale and computers (Mac and pc) but nothing.
The unit turn on and get lock in the splash screen.
Is there a way to reinstall the firmware via a SD card or
perhaps do a re install with a JTAG/SWD by hooking up the motherboard directly.
Garmin was no help. They told me to buy a new one :(
and offer me $20 ☹️
Anyone more knowledgeable around. ?

I've no idea about how it works on a Mac, as all the firmware flashing I've done (Mainly flashing 590 to 595) has been under Windows. If you can get the use of a PC, it might be possible - I just don't know - to reflash it using the 590 to 595 technique. Have a read through this thread:

Bear in mind that the links in the thread to the Dutch forum no longer work, but there are sufficient instructions in that thread. Good luck!
