Staying on the topic of CyanogenMod, one thing that does get a little over the top when you have CM running on your Android phone is the updates. And downloading the entire ROM update every night can be a bit of a pain in a country like India where the internet connectivity is not a luxury that everyone has. However, what if you knew magically every file that has been changed by the CM team in the nightly update and only those are downloaded and updated on your Android phone running CM ROM and update is patched with the latest version?
In theory it sounds great, in practicality, it is even better. Up steps, an application called CyanDelta which as the name suggests, will only download the delta files when the ROM is being updated. The application will then go on to update your smartphone, ensuring you are always on the latest CM files and do not have to depend upon large bandwidth internet connections.
Main features of the application, as written down by the developers are as follows from Google Play, mind you CyanDelta is recommended by CyanogenMod themselves, though it is not directly produced or affiliated to them:
? Security: all downloaded data is digitally signed by us to prevent manomissions.
? Recovery zip install: it can automatically reboot to recovery, install the ROM zip and other additional zips (kernel, modem…), wipe dalvik cache and reboot (requires root).
? Changelog: if you have a NIGHTLY build, when an update is available, CyanDelta will show you the list of changes between the ROM version you have installed and the new one.
? Update notification: when a ROM update is available, CyanDelta will notify you.
? High efficiency deltas: it uses the RFC3284 VCDIFF algorithm and some magic to produce really small deltas.
? Supports TWRP and CWM-based recovery, but NOT the closed-source ClockworkMod (the name is similar to CWM-based, but it’s a different thing!), since it’s locked down by its author to only work with ROM Manager. If you have an unsupported recovery you can just manually install the zips generated by CyanDelta.
? Supports all official CyanogenMod ROMs and devices listed in http://download.cyanogenmod.org
