blue screen after installing monitor brightness kext

[christy123]

i installed iatkos v 7 successfully on x61 tablet and then installed a kext for " brightness control" from one of the posts. now, after i restarted the tablet, all i see is a blue screen

is there a way around this. system restore equavalent? does one have to reinstall everything everytime a small file misbehaves?

 

i will appreciate your help

Ideally, you would have a Time Machine backup at best and a backup of your Extensions folder at worst, in case something goes wrong. But you apparently don't, which means that all you can do is try to remove the offending kext and hope that nothing else is screwed up. What you can do is boot off the iAtkos disk, mount your drive using Disk Utility, open Terminal from the utilities menu, and do

rm -r /Volumes/DRIVE_NAME/System/Library/Extensions/KEXT_NAME.kext

Beware, that command is essentially an unforgiving delete command. Mistyping the path could have disastrous results. (For instance, put a space after the DRIVE_NAME and you just nuked your hard drive )

Oh, you'll need to force rebuild your kext cache with the -f option at next boot.

Thanks very much! I dont have any data on it yet. So dont have to worry about nuking the hard drive.

 

Does Time machine work only with time capsule or can i use any external hard drive to backup.

 

i am hoping Apple will come out with Tablet soon and i dont have to this .

You can use any external hard drive, thought you might want to do some more research before investing in it. Someone just told me that you can't do a full system restore with it, possibly because it doesn't preserve the bootloader. Even if that's the case, I would imagine you can just reinstall the bootloader or use EasyBCD. Regardless, TM still works for restoring individual files, I've done so myself.
