Like Koush's ROM Manager, XDA Member elegos's ROM Updater performs many of the same tasks and more for free and without ads. ROM Updater is a stand alone repository based updater, which allows you to add repositories to pull from, along with allowing full and incremental ROM updates. ROM Updater has the following features:
- Full Recovery Control
- Version Recognition for ROM Updates
- Full Updates
- Incremental Updates (Increment Creator tool available for developers)
- Backups
- And More
The app is available free on the Android Market and in the discussion thread. Be sure to thank the developer and leave feedback in the thread.
