Using a ldr.bin, aka boot.bin, from another device's fw is very risky and potentially will hard-brick it by writing an incompatible bootloader to region 5. It's not possible to know if a different device's ramloader (boot.bin) will be safe unless it's been tried and reliably reported so i highly recommend you not be the first.
Drive 52 is identical to Drive 5 Pro in that they use the same firmware and share a HWID. I'm unable to personally confirm that their HWID is 3061 however if you've used G7ToWin correctly and it's reported 3061 then that's reliable.
Do you have a file system backup of the device, even an old one? If so, it may be possible to use that to download the correct firmware from the Garmin server.
