Connect your calculator to computer with ON/C key pressed down. Then you can use ExistOS Updater to unbrick it.

If https://github.com/ExistOS-Team/ExistOS_Updater_v2 broke the base of the machine??

Is there a new device appeared in Device Manager? Or you can use another computer and try again. STMP3770 has On-Chip Rom inside it, so it's not that possible to brick it.

Yeah,same cable,same PC.SUCCESS flash it!but I found another problem: I use the ExistOS Update tool ,Choose lastest OSloader and system.Use hostlinkmode. I can boot the system now but it run in the RAM.So I can't shutdown or do anything about power. How to flash OSloader on this machine so that make it work?Only can do this by using Ninja?

ExistOS Updater will flash OSLoader and System to flash after sending OSLoader to calculator RAM.

For example, I use HostLink mode to update my device, and after I pressed the Update OSLoader&System button, the application will send OSLoader to calculator RAM. Then, the calculator will reboot automatically, and the updater will flash OSLoader and System to calculator flash. Finally, the calculator will reboot the last time and enter the system. That's the whole progress of updating using HostLink Mode.
