Acer R856TN - don't turn on after disabling CCD

Support General Device Support

Hello,

I have Acer R856TN and after tests with RW_Legacy tests I decided to go with Full ROM. I removed battery and using MrChromebox guide I started to enable CCD. I reached point where device should reboot in Normal/Verified Boot Mode but instead of this it doesn’t run at all. Power led blinks once white/blue + 4 times red and it’s repeats every couple of seconds…

Power / Power + F2 / Power + F2+Esc doesn’t work. Is it mean that device is bricked and I need to use Suzy-Q to recovery it?

edit: I am able to run recovery mode using Power+F2+Esc and than enable Developer Mode but when back to terminal mode it looks that CCD is locked. When I use gsctool to enable CCD it’s run but I finish again in same place

You should not disconnect the battery when running the gsctool command
