How to flash Lenovo Yoga Book that doesn't boot into the OS?
I've acquired a Lenovo Yoga Book (YB1-X90F) that doesn't boot into the OS. I can access the bootloader and recovery environment.
I've followed the guide over at https://forum.xda-developers.com/t/yoga-book-yb1-x90f-android-how-to-flash-back-to-stock-rom-6-0-1-downgrade.3709930/#post-74627585 that uses Intel Platform Flash Tool, but I get errors straight away. Another person has the same problem--2nd to last poster.:
02/20/22 15:54:20.155 ERROR : [Port 1/7] Command `"C:\Program Files (x86)\Intel\Platform Flash Tool Lite\fastboot.exe" "-s" "YETIDD2E4EC8" "flashing" "unlock"` failed 02/20/22 15:54:20.155 ERROR : [Port 1/7] Flash failed (Command type: Fastboot)
I've also installed Minimal ADB and Fastboot but I don't know what I'm doing.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices YETIDD2E4EC8 fastboot
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices List of
C:\Program Files (x86)\Minimal ADB and Fastboot>
The ROM I got (YB1-X90F_USR_S000196_1611040312_WW06_BP_ROW-flashfiles.zip) from some random site includes what looks like some info or installation steps in the .zip, but even with Word auto-translation into Chinglish, I don't understand what is being said.
Any input would be greatly appreciated.
Solved. I ran 'flash_update_from_user.json
Just waiting for the battery to charge to 30% to hopefully enable the Halo Keyboard.
