It seems that my instability problem happens when I keep the lid closed, the computer will randomly shut down, as if it ran out of power or got too hot, which are not the case. Maybe it's some lid related sensor?

If power management and backlight control is implemented correctly, your computer should enter sleep when you close the lid. Note that it is a bad idea to leave the AC power unplugged while a hack laptop is in sleep... Because hibernation is generally disabled, sleep mode will drain the battery completely until the laptop shuts off.
 
I got my hp dv7-4295US internal monitor (lvds) and HDMI both working, with hardware acceleration and even extended desktop!!!

Inject EDID - vendor 0x1002 - product ID 0x68c0 (ATI HD5730/6570 mobility)

BABOON framebuffer and

patching AMD5000controller this way:

Using clover configurator, Kernel and kext patches, kex to patch,

find:

04000000 14000000 00010000 00000000 01020103 00000000

Replace for:

02000000 40000000 19010000 00000000 00000005 00000000


This patch will replace the first connector hex from DP to LVDS, and keep the other two connectors (HDMI and VGA) untouched

Still no hdmi audio yet, only analogic audio.

Nice! Congrats!
I have since sold my unit of this laptop, but it's nice to see it working strong!

Hi , I am trying for months to make my hp dv7 4290us boot normally on Sierra, I tried your video patch above. Still no luck, is it possible to upload your EFI clover folder? please....
