Hi, a couple of hours ago I decided to edit the build.prop to change lcd density, so I went to the market and got myself Lcd density modder, made the change and rebooted, unfortunatley the phone no longer boots.
I then searched for the solution to this problem, here on xda and on a bunch of other forums, and all agreed on the same solution, I had to replace the bad build.prop with a good one. Once again murphy's law knocked and I had no backup, so I grabbed the rom that I was using extracted factoryfs.img and and managed to extract the build.prop thanks xda.
For the next step I booted the phone to the recovery and using adb pushed the new file, the thing is the phone still does not boot. I tried using adb shell to check the permitions, but every time that I try to su I get a segmentation fault. I've already wiped the cache and dalvik-cache a bunch of times to no avail.
Can anyone help?

Next time, use Rom toolbox to edit your build.prop.

Boot to CWM recovery, then use ADB to restore your backup build.prop

Reflash your current FW or flash ParanoidAndroid if you like to change DPI.

If you can wait for 1 hour, then i will upload a flash template for you as soon as i get to my pc.

If not just flash your ROM back, you won't lose any data

Thanks for the offer, but I just reflashed it, seems to be working fine, just have to root it again, and should be good to go.

Thansk for the help

Hey, I also destroyed my build.prop and now my S2 is hanging in a bootloop. I can connect via ADB but I have no stock build.prop and dont get to extract it out of factoryfs.img. Can anyone support me by helping me to exract a stock build.prop or post all the info that has to be in the build.prop. That would be very nice.

Thanks, SmilerGrogan

PS: I am running Android 4.0.4 (german Telekom branding)
