[Q] read file from data.ext4.tar.a


I have backed up my Samsung Galaxy SII i9100 using clockworkmod, and installed the CyanogenMod. Apperently my saved wifi settings, are not restored, and I wondered how to get them back.

I tried restoring the original Samsung image, but it seems broken as after booting the device, i can't see anything on the screen (but I can access it with adb). Now, since the wifi settings are stored in /data/wifi/bcm_supp.conf, i thought retrieving this file from my backup files (i assume this file must be in the data.ext4.tar.a file). But I have no clue how to open or mount this file. Is it possible to just get this file and store it in my new installation, or should I try something else?

thanks for you reply,
