mrjayviper Posted June 15, 2014 Share Posted June 15, 2014 Hello. I have created my bootable USB using myhack and the 10.9.3 as download from the AppStore. Anyway, I have tried rc6 and rc7 FX kernels and have replaced System and Sandbox KEXTs. In both cases, it results in a blank screen (my monitor says power saving mode). I'm not sure how to extract the dump the screen so I took a video. from what I can see the last 4 entries before the screen goes blank is probe start Built-in decrypter used [IOBluetoothHCIController][start] - completed blank screen here I am using 10.9.2 right now and the only KEXTs I needed to replace are the ones I mentioned above. I am using chameleon (like what I used in 10.9.2) and used the flags "-f -v npci=0x2000". Any ideas what could be wrong? thanks very much in advance. ps. my setup is in my sig. edit1: I tried installing without using patched KEXTs and still the same results and error. edit2: I used myhack to create the 10.9.2 USB installer and that works fine. edit3: I've tried 2.1 Kernel/Kext from niresh and still no luck.

zerking Posted June 17, 2014 Share Posted June 17, 2014 I have no luck at all trying to update to neither 10.9.2 or 10.9.3. Whatever kernel I tried, I still got a white screen with spinning wheel. The only way to get to desktop is trough safe mode (boot with -x) Any idea on my case? Link to comment Share on other sites More sharing options...
Saerith Posted June 17, 2014 Share Posted June 17, 2014 This is strange, because I updated to 10.9.3 without problems using 2.1 kernel from Niresh. Also, you could try like this: 1. Backup your working mach_kernel and S/L/E folder 2. Update to 10.9.3 3. Boot with usb to terminal 4. Replace new mach_kernel and S/L/E with backuped ones (don't forget to back new ones too, just in case) 5. Fix permissions (chown -R root:wheel / chmod -R 755) 6. Restart and boot from HDD Some users are reporting that this method works. Also this is method i updated to 10.9.2 with (Well, I used different mach_kernel and ADDED kexts tho). Good luck!

zerking Posted June 19, 2014 Share Posted June 19, 2014 I tried your method Searith, but no luck at all. Still stuck at white screen and colorful spinning wheel.... @_@ Awr....... so frustrated !!! Link to comment Share on other sites More sharing options...
Saerith Posted June 19, 2014 Share Posted June 19, 2014 You tried old (10.9.0) and new (modded for 2.1) kernels and none of them work? Makes me think, there is something with VGA, because I have same CPU and it worked like charm. Also strange thing is that You don't get kernel panic, which should be in case of wrong kernel / kexts - so that makes Me think more that it might be VGA issue...

zerking Posted June 20, 2014 Share Posted June 20, 2014 Yeah, that's my thought as well... hmm.. but I don't have other VGA to do the test (sad thing). I thought HD 7770 is natively supported by OS X, but it seems like I'm wrong then. Do you have any other suggestion for me on this quest of conquering my VGA (LOL...)
