Same situation: in my ACER ASPIRE ES1-111M-C1LE after installing ukuu I put linux v4.14.9 and v4.14.10: both don't solve my problems with the bios. my idea was to follow this guide to flash the bios: https://askubuntu.com/questions/144526/how-to-flash-a-bios-when-only-a-windows-binary-is-provided
I tried to make a backup of my bios with 'flashrom' and the result is: # sudo flashrom -p internal -r backup.rom -o backuplog.txt flashrom v0.9.9-r1954 on Linux 4.14.10-041410-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop... OK. No DMI table found. Found chipset "Intel Bay Trail". Enabling flash write... Warning: BIOS region SMM protection is enabled! Warning: Setting Bios Control at 0x0 from 0x22 to 0x01 failed. New value is 0x22. Warning: SPI Configuration Lockdown activated. FREG0: Warning: Flash Descriptor region (0x00000000-0x00000fff) is read-only. FREG2: Warning: Management Engine region (0x00001000-0x003fffff) is locked. Not all flash regions are freely accessible by flashrom. This is most likely due to an active ME.

You can enforce write support with the ich_spi_force programmer option, but you will most likely harm your hardware! If you force flashrom you will get no support if something breaks. On a few mainboards it is possible to enable write access by setting a jumper (see its documentation or the board itself). OK.

Main issues were Settings being not stored, USB Boot impossible and EFI entries read- only. Fix: The issue was fixed in Kernel Version 4.13.0-21. But previous affected machines still suffered from a broken BIOS. Repair: Boot Linux and Install Kernel Version 4.14.9. Reboot into Linux and BIOS should be restored to a working state. --- Test Case: Fix has been verified by our HWE team on affected hardware. Regression Potential: Minimal, it's unlikely anyone is actually doing anything which requires this driver. --- Affected Machines: Lenovo B40-70 Lenovo B50-70 Lenovo B50-80 Lenovo Flex-3 Lenovo Flex-10 Lenovo G40-30 Lenovo G50-30 Lenovo G50-70 Lenovo G50-80 Lenovo S20-30 Lenovo U31-70 Lenovo Y50-70 Lenovo Y70-70 Lenovo Yoga Thinkpad (20C0) Lenovo Yoga 2 11" - 20332 Lenovo Z50-70 Lenovo Z51-70 Lenovo ideapad 100-15IBY Acer Aspire E5-771G Acer Aspire ES1-111M-C1LE Acer TravelMate B113 Toshiba Satellite S55T-B5233 Toshiba Satellite L50-B-1R7 Toshiba Satellite S50-B-13G Dell Inspiron 15-3531 (not fixed by 4.14.9) Mediacom Smartbook 14 Ultra M-SB14UC Acer Aspire E3-111-C0UM --- Original Description: Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users reported a corrupted BIOS. It's not possible to save new settings in BIOS anymore and after rebooting, the system starts with the old settings. Moreover (and most important) USB booting is not possible anymore since USB is not recognized. It's very serious, since our machines do not have a CDROM. Lenovo forums at the moment are full of topics regading this issue. Thank you!!
