gpicon said:SapientSlayer said:i5 760, GA-P55A-UD3, XFX 5770 running on 10.7 lion with no flashing of GPU!
GUIDE: I had a running build with 10.6.7 so anything before i cant comment on
1. to upgrade to 10.6.8 i first backed up ATI5000Controller.kext, ATIFramebuffer.kext & ATISupport.kext from 10.6.7.
2. download and install combo update 10.6.8(not software update.
3. DO NOT RESTART... you need to install ATI5000Controller.kext, ATIFramebuffer.kext & ATISupport.kext using kextbeast then repair permissions and cache.
4. RESTART and 10.6.8 should work.
5. download lion from app store and follow tonymacs xmove instructions... if everything installs then restart.
6. at chimera boot screen boot into installer partition using GraphicEnabler=no -x
7. this should boot you into lion installation. install and restart
8. at chimera boot screen boot with GraphicEnabler=no -x on Partition you installed lion on.(first time i did this i got a KP but restarted and did it again no problem)
9.once in lion i did the same thing as i did in 10.6.8 with ATI5000Controller.kext, ATIFramebuffer.kext & ATISupport.kext from 10.6.7 and repaired permissions and cache.
10. restart and booted into 10.7
I can confirm that this worked without flashing. Thanks SapientSlayer.
Warning: do not flash your 5770. I bricked one of my 5770A-ZNFCs with XFX.HD5770.1024.090926 and now it won't even POST.
What is the difference between upgrading from 10.6.7 (what I did) to Lion and 10.6.8 to Lion? I'm using rollback kexts from 10.6.7 and my lion works, but as another user mentioned there is no QE/CI or acceleration of any sort. I'll try to install Lion over 10.6.8 soon and see how it goes.
