[Galaxy Tab 2 General] shinobisoft:
Here's my fixed updater-script. It installs clean. But it DOES NOT boot. Went thru the installation and left my P3113 to boot while I went to the store. Came back 20 minutes later and still stuck on Galaxy Tab splash screen :(

I am positive there are some files missing from the device specific part. Just haven't had time to figure out what they are and where to get them from.

I have added some ui_print() statements so that there is an indicator of some kind of progress.

assert(getprop("ro.product.device") == "p3113" || getprop("ro.build.product") == "p3113" ||
getprop("ro.product.device") == "GT-P3113" || getprop("ro.build.product") == "GT-P3113" ||
getprop("ro.product.device") == "p3113" || getprop("ro.build.product") == "p3113" ||
getprop("ro.product.device") == "GT-p3113" || getprop("ro.build.product") == "GT-p3113" ||
getprop("ro.product.device") == "espressowifi" || getprop("ro.build.product") == "espressowifi" ||
getprop("ro.product.device") == "espressowifixx" || getprop("ro.build.product") == "espressowifixx");
