hi,
first of all, thanks for reviving ESPTool C# project.
I'm trying ESPFlasher with different kind of ESP32 device, but could not get it work. For example, ESP32-S3 (with chip model 0x9) should work if i change the code (at least bootloader sync or erase) but always got:

with another device, erase just hangs with Attempt 1. My guess is that for some reason these chips could not go into bootloader with the specified sequence. Could you tell me what is your ESP32 device model that worked for you?
