It has nearly been four years since HP launched its ill-fated TouchPad tablet. The tablet came at a time when almost every other manufacturer was trying to develop its iPad-killer but almost all of them failed. TouchPad was a monumental failure and HP had to launch a fire sale just to get rid of the units that it had produced. However the tablet found home with a dedicated community that swapped its webOS software for Android. The same community has released an HP TouchPad Android 5.1 Lollipop ROM which works better than you might have expected.
This is surprising because of the fact that the TouchPad’s hardware is over four years old by now, yet it’s quite capable of running this Android 5.1.1 Lollipop ROM.
Based on the Android Open Source Project, the Evervolv ROM for the TouchPad is based on Android 5.1.1. It brings almost everything that you would expect from Lollipop to the tablet.
However since this is a ROM developed by a third-party one has to keep in mind that the installation process can be a bit tricky, particularly if you’re not used to tinkering with custom ROMs for such devices.
All of the instructions have been posted by the developer on the XDA thread, be warned though this process requires quite a lot of tweaking before the TouchPad can run Lollipop.
