Upgrade the Original Galaxy Tab P1000 to Ice Cream Sandwich via MIUI 4

Finally, the original 7-inch Samsung Galaxy Tab gets to taste some Ice Cream Sandwich.  Thanks to a MIUI 4 port for the original Galaxy Tab P1000, the tablet can now enjoy some of the goodness of Android 4.0.

A member of XDA Developers, sinamosavi, was able to port the MIUI 4 ROM to the Galaxy Tab.  The ROM is based on CyanogenMod 9, which in turn is based on stock Android 4.0 code from the Android Open Source Project (AOSP).

The custom ROM for the Galaxy Tab is still an alpha build, so you can expect it to carry several bugs.  Among the known bugs included in the ROM are all bugs carried over from CyanogenMod 9.  Wi-Fi and SD mounts are also reportedly problematic.

Considering that the original Samsung Galaxy Tab is already an old device, it doesn’t have to be left behind on the latest Android version.  So, if you want to enjoy Ice Cream Sandwich on your tablet, read on for the instructions on upgrading your Galaxy Tab P1000.
