Why do I have to suddenly do this with clips and special programmer? I followed your steps described in readme file and now my laptop is fully broken or what, until I somehow get that clip?
Anyway, your laptop must be reflashed.
You can do it yourself using programmer+clip+my help or...
you may bring your laptop to repair service, they can recover bios.However, it'll cost more expensive.
If you want get unlocked hidden settings,you should get/buy these tools.
If you have programmer,you can easy recover laptop if you brick it
Ok, how do I know what programmer I need? And what clips?
it may be standard cheap programmer ch341a with Pomona SOIC8 clip, however you should contact with seller if hardware support your bios chip.
You can buy these tools at Ebay, Ali and another online-shops.
I somehow managed to get screen.
I've tried several things so far, reset CMOS, tried to recovery flash stock a14 bios, took out gpu, took out display and nothing of these worked. However, there seems to be a second connector called EDP which looks like exactly the same connector, right above the one where the original was plugged in. When I insert the LVDS cable into the second connector, I get no more beeps but display also doesn't turn on. When I inserted my gpu again, with the LVDS cable into the EDP port and an external display, I get screen on my external monitor and I can use my laptop as normal again. I flashed original stock bios. So how do I fix my laptop screen now?
EDIT: I narrowed it down a bit. I looked into bios and it said Integrated GPU: (none detected) which was very strange to me, I have never disabled it before. So after booting into OS I looked into device manager and HD 4600 was missing. It was just gone. So I pressed FN + F5, it asked me if I wanted to enable integrated gpu, I said yes and laptop restarted. Then it was the same issue again, black screen with 2 grey lines. So any ideas? How do i re-enable HD 4600?
It sees HD 4600 have hardware failure,this GPU integrated to CPU.
So if you want to see HD 4600 in device manager again, you should replace CPU.
However,there is one bad thing.
Mobile Intel Cores before 4th generation produced in PGA socket, so CPU can be replaced by user without problem.
New processors have BGA socket,it means your CPU is soldered.If you want to change CPU,you need infrared solder station or bring laptop to repair service (they can do this job).
It's an Intel core i7 4700mq, I can take it out.
So your modified bios destroyed my hd4600? This problem only started right after I flashed your bios.
No, modified cant destroy your laptop component, it is just changed code with unlocked tabs (I did this many times, all are successed)
However users who wants to get hidden settings,they must be Power users and know what they do.
Changing of some hidden settings can be brick laptop, only programmer can recover laptop.
If you disable integrated GPU, you'll get black screen after restart.This operation is strongly not recommended.
We can try to recover your laptop using another dump.
Tell me your full laptop model and motherboard.
