Download ROM updates for CyanogenMod, MIUI, AOKP or for alternative ROMs (manual repository).
Note that this application is for people who know the correct procedure to install / update a ROM.
For example, if you install a major update (eg Android 2.3 to 4.0), you need to WIPE / Cache to avoid conflicts and errors. Follow the procedure and it is not the fault of System Updater if you encounter an error.
Do not forget to write me a mail if you have good ideas to offer.
Thank you and hope you enjoy System Updater.
