Unable to boot installation usb. Stuck at [EB]#LOG:EXITBS:START]

[LouisLynn]

I had a 20R1 model and my laptop stuck at booting process. I googled the error code [EB]#LOG:EXITBS:START], and it seems to related to CFG Lock. I could not find the option to disable CFG lock in bios, and neither AppleCpuPmCfgLock nor AppleXcpmCfgLock in config.plist works for this issue.

what is your laptop specs?

X1 Carbon 7th Gen - (Type 20R1, 20R2) Laptop (ThinkPad) - Type 20R1
i7-10710u Whiskey Lake(based on Coffee Lake) / LPDDR3 16GB onboard / Intel® UHD Graphics for 10th Gen Intel® Processors
BIOS : 1.34 (N2QET40W)

Processor Number	Code Name	# of Cores	# of Threads	Base Frequency	Max Turbo Frequency	Cache	Memory Types	Graphics
i7-10710u	Whiskey Lake(based on Coffee Lake)	6	12	1.1 GHz	4.7 GHz	12 MB	LPDDR3-2133	Intel® UHD Graphics for 10th Gen Intel® Processors

btw I found same issue of this model on github: https://github.com/bomdurup/x1c7_2020_hacintosh, it seems that the cfg lock is an universal problem on Lenovo laptops.

@LouisLynn Does it work?

Hey all,

I actually got my laptop back from Lenovo while they fixed a hardware related issue and since it's return (and bios upgrade... ugh) I've been completely unable to get this repo's EFI. I have the older i7-8665u but I'm also stuck on EXITBS.
@LouisLynn did you have any success?

Hi all,

I tried @huyhoang8398's EFI and still stuck on EXITBS, then I modified the Cpuid1Data and Cpuid1Mask based on 20R1 model (in @aidanchandra's guide). Now I passed the EXITBS, but still stuck here:

I am sorry that I have to show you the error code by a photo, I am new to hackintosh and haven't figure out how to export the code...
