Thread: GarminCure3 tool - the new way to create cure firmwares for Garmin devices

But no, pre-boot mode has to work, because bootloader inside boot.bin is not patched.
You can flash some garbage instead of fw_all.bin and pre-boot mode would still work on 99% of Garmin devices (on GVN53 it won't, sadly). This proves that pre-boot is not implemented in fw_all.bin. And GarminCure3 patches only fw_al.bin.
The answer seems to be too obvious... Maybe I didn't understand you.

What I meant is that the SD card method using update.txt and LDR.Bin won't work when GarminCure3 is loaded in cure mode.
I wrote updater.exe instead of update.txt (blonde moment).
