Hello, I am student In KOREA..


I want Install NEXUS7 2012 images on my NEXUS7 device.


I have downloaded 4 image files, boot.img,  system.img, userdata.img, recovery.img

on http://snapshots.linaro.org/android/~linaro-android/nexus7-2012-linaro/lastSuccessful

 

and I tried porting these files on my device using fastboot like this command that "fastboot flash boot boot.img"...

 

but my device is blocked and the logcat error message tell "couldn't find an OpenGL ES implementation"..

 

I can't solve this problem, can you give some solutions? and i attached logcat file with this mail.

 

and if I use linaro_android_build_cmds.sh..., How can I install?? I read the guide but there is only way install on sd card...

so I don't know make image files without sd card...

 

Thank U!!!
