Hello.
After upgrading from 10.7.3 to 10.7.4 using instructions from the 1st post I'm no longer able to boot into system (LY479EA#ACB, F20, i5-2450M, 4Gb, IntelHD)
After white logo there should be lightblue screen blink and then logon screen. But instead of this I get a glitched screen full of magenta/blue (or other random colors) vertical lines (like on dead videocard).
I tried multiple ways to recover:
- rBoot/rBoot-LE
- By putting NullCPUPowerManagement.kext into /S/L/E
- By deleting AppleHDA.kext and AppleIntelSNBGraphicsFB.kext from /S/L/E
- By replacing kext in /S/L/E and SSDT.aml/dsdt.aml in /Extra (from HP Probook Installer, MultiBeast and Patched 10.7.4)
Nothing works. I don't understand what is wrong.
All I can is to boot from USB-stick with 10.7.3 Installer and manipulate files with Terminal.
Any ideas?
