CyanDelta Updater- Update your Cyanogenmod ROM (CM) just with a small delta file

Every Android device comes with an official stock firmware installed in it. The qualities and features that this firmware provides depend on the specific Android device you’re using. But there comes a time when everyone gets bored with this stock ROM and thinks of buying a new high end device with more unique features.

But if you’re an advanced user then rather buying a new phone you’ll go for the Custom ROMs. These are basically the un-official releases giving the best and better features as compared to Stock. With Custom ROMs, you can overclock your phone and even can change system settings of your phone. Basically you can attain a full control over your device. But before installing any Custom ROM you need to root your device. Remember that rooting will void your phones warranty which can be easily gained back by un-rooting.

Cyandelta-ss1Cyanogenmod Nightly is the most downloaded and preferred Custom ROM among Android users. Nothing beats it in terms of bringing a whole new experience to your device with more tweaks and eye-catchy features. The main reason behind its popularity is the features that it provides are bug-free and secondly it is updated weekly.

When any new update for CM nightly arrives, you need to download the zip file, copy it in SDcard and install it through recovery mode. It’s pretty much easy, but the zip file that you need to download is almost 200+ Mb file which requires a proper Wi-Fi or a good network connection.

Just think if this zip file would have been of 10-20 Mbs then it would have been so easier to download it. A 10 Mb file can be downloaded in not more than 10 minutes (depending on your net connection). But it’s clear that it would definitely not take much time than downloading a 200 Mb file.

If you’re using CM nightlies and want to update your ROM without much efforts then CyanDelta Updater is the only app you need. CyanDelta lets you update your CM nightly ROM by downloading just a small delta file (as the name suggest) of about 10 Mb instead of that big zip each time. All the credit goes to Mattia Baldani, the main developer of Cyandelta updater.

Firstly download the base nightly. Then launch CyanDelta Updater app and set your base version. This app will then automatically check for latest updates on a regular basis to get you incremental downloads. CyanDelta figures out whether a new update is available by checking If there is, it will notify you to download it. More of its feature re listed below.
