Looking for an unmodified ROM for the Samsung Galaxy Tab S that is flashable via TWRP? An XDA user has developed a ROM that is based on latest Android 5 Lollipop firmware from Samsung. It is not rooted but is ODEXED. It is a full ROM with nothing removed with working boot animation and is based on latest firmware.
To install it you need the latest lollipop bootloader, so make sure you are on official Lollipop Tab S ROM before you flash it. To install it, download it to the root folder of your Tab S and then reboot into TWRP recovery.
Again while this ROM is nothing special when compared to the one officially available, it is odexed and for many that is very important.
