Dual-boot between Sense and Google edition ROMs on your HTC One, with a single set of app data
Update: For those interested in having similar capabilities on the Galaxy S4 (GT-i9505), MoDaCo has an Indiegogo project set up to raise £1000 ($1500) to bring Switch to the GS4.
MoDaCo Switch, revealed a couple of weeks ago, is a unique custom firmware allowing you to switch between HTC Sense and vanilla Android on the HTC One. The software comes as two ROMs in one, with a "Switch" app in the app drawer allowing you to hop between the two flavors of Android. Even more useful, MoDaCo Switch does all this with a single set of user data, meaning apps and accounts are shared between Sense and stock.
It's been in private testing for a few days, but today creator Paul O'Brien has released the current build — beta 8 — to the public. There's a little bit of initial setup to go through, so you'll want to check out the full list of installation instructions before you get started, even if you're familiar with flashing custom ROMs. It's also worth noting that right now only the GSM HTC One is officially supported in MoDaCo Switch.
We've been testing MoDaCo Switch on the European HTC One for the past couple of days, and we've found it works just as advertised. It's a great way to live in the Google Play ROM if you prefer the look and feel of vanilla Android, while having the ability to escape back to Sense if you need to use a certain feature, or if you just fancy a change. And when you do switch over, all your app data and accounts are preserved.
