1. Make a copy of your v3.4 ET
2. Replace the old build.prop inside the copy of v3.4 with the new build.prop that I just sent. You can find it inside the v3.4 zip file: /system/build.prop
1. Make sure that your system is working properly before installing the modified v3.4 above
2. Boot into your custom recovery and install it without any wipes. Just install and reboot when it is done..
Please report back if it works...
I can not upload the zip file at the moment. I will try again soon...
