build.prop - Galaxy S III Q&A, Help & Troubleshooting

Hello people!
I'm with a big problem here. First, I'm a newbie on Android, but I searched a lot before do this question. Ok, I bought a SGSIII some days ago, and I did a root on it. So, I wanted to change the resolution of cell phone: I edited build.prop to 240DPI, and rebooted the phone.
But so, Samsung's TouchWiz stopped working! And I can't access Root Explorer anymore... I installed Android Tools on my PC, and I tried to push, remount, use adb shell (+su, +mount on system partition), but nothing works. I ALWAYS find a new error. For example, after mount the partition in the shell (and exit, of course), I got "Permission denied" on adb push. Just see:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Anybody knows what I should do?
Thanks ^^

Try reflash with your original firmware using odin.

Make a flashable zip and flash it through cwm

Adb remount command won't work unless you flash an insecure kernel or use insecure adbd app from chainfire. If you can boot into your mobile and getting launcher force crash better push a secondary launcher app like apex or nova via Adb and reboot now use the second launcher to make changes. Stock launcher will jot work @ 240 dpi

i think this is the best option...
get any flashable zip..uynzipit and look at it...youl qquickly get where to put build.prop and what to modify... then compress it (without the old signature) again and sign it
launcher keep crushing because stock touchwizz doesn't support another dpi. you should mod it or find one moded

I'm just stupid! How I didn't think this? It worked man! Thank you! s2
Thanks to all people tried to help me too (Arsaw, E_Goldstein, nodstuff, bala_game and pelpa87)! I don't know how to sign in a Flashable Zip, but it doesn't care any more. I'll unroot this device, else I'll do stupidties again...
