Expected Behavior
[coreboot bios screen then install OS]
I have done this on at least 10 Chromebooks with no issue. I suppose USB C cable wiggled during flashing as I grabbed at cat causing damage. I have RTFM and ordered a SusyQ cable. I just want to confirm I am on the right track. I should be able to flash Full UEFI to ROM chip on Lenovo Yoga C13? This laptop is almost flawless and has a cool blue case. She is lovely and would hate to part her out. I was excited to have 8G RAM and 8 cores with replaceable NVMe. Please reassure me that I can rescue this one.
Sorry to hear about your incident with the cat… The good news is your laptop can probably be saved.
I would treat this machine as bricked. Follow the instructions here:
I can recommend the SuzyQ route. You can either flash the recovery image you made and try the script again, or follow the instructions there to download the UEFI version.
From my personal experience I can recommmend to read the instructions carefully before starting and having a good idea of what step comes when. Double check you have the correct firmware for the correct board. You can always come back here with questions.
If the machine is in fact bricked then the SuzyQ cable should be able to save it, but try reconnecting the battery, plugging it in, resetting the EC by holding Esc, Refresh, and pressing the power button on the side (the power LED should flash 3 times and the orange light next to the USB port should turn on but the laptop probably won’t), and letting it charge for 15 minutes before attempting to turn it on again. I know it sounds crazy but my MORPHIUS acts like it’s bricked every time I accidentally let the battery run dry if I don’t do this.
I am replying from my now working morphius laptop. SuzyQ cable worked great. It was an interesting process. I rescued another one from recycling. I use FTDI serial cables to program old network equipment such as old cisco switches and routers along with vintage phone systems in my day job so how does the SuzyQ cable actually do it’s thing? I see there are 3 tty devices created by it. Thanks everyone for info and encouragement.
the GSC (CR50) provides 3 serial interfaces to access the CR50, AP (main CPU) and EC consoles on ttyUSB0/1/2 respectively. it also provides a direct bridge the SPI interface via the flashrom raiden programmer. the SuzyQ cable allows for the CCD interface to the GSC by abusing the USB spec a bit.
