But this one will now work. Run as admin, Also did the, run cmd box as administrator, then, C:\ bios_name /forceit Neither work. Unless there is a 3rd party flash software I can use? May not be safe? This last update was to cover vulnerability in CPU kernel? Screen will light up if I boot without dsdt, but it runs like C#@P, and it takes over 5 minutes to boot. Maybe needs a DSDT edit? HD3000 graphics set to defaults in Clover. Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 10, 2018 Moderators Share Posted September 10, 2018 If you can't downgrade, then re-patching DSDT is the next route. Boot to Clover, press F4. Then compress and attach the Clover folder here. I'll try to retrace the patches used to the new files. Quote Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted September 11, 2018 Moderators Share Posted September 11, 2018 try this, Replace Config, DSDT and SSDT-PNLF goes into /EFI/Clover/ACPI/Patched and AppleBacklightInjector.kext goes into /L/E Repair permissions and rebuild cache 3520.zip Quote Link to comment Share on other sites More sharing options...
morpheousman Posted September 12, 2018 Share Posted September 12, 2018 Thanks for the help. LCD lights up, but it's a bit buggy. Sometimes boots up like I would expect. Other times, it takes longer to boot, and then when it reaches desktop it has brightness all the way up, there is no brightness control in Preferences >> Displays, and Icon for dual-monitors is showing like there is a projector or another monitor hooked up. Then it can take anywhere from 1 to several reboots to get it to boot to normal desktop. Quote Link to comment Share on other sites More sharing options...

morpheousman Posted September 13, 2018 Share Posted September 13, 2018 Well, I probably did a mixture of boot & reboot 25 times, and that one is working. Only thing is that the brightness always boots at 100%. Trying to figure out why it won't save brightness setting, I thought I had working NVRAM.
