Our readers already know about CyanogenMod, as it's only the most popular Android ROM out there, so I won't waste time with an introduction. Many also already use CyanogenROM Downloader to get their hands on the latest versions, even though it's not an official updater. The app's already awesome, but its author sent out a tease a few days ago implying that it could be even better - that it could automatically update your ROM to the latest version overnight, do a backup beforehand, and install your preferred custom kernel without a single touch. Today an update has rolled out making all of these things come true.

What's new:

  • Added Flash function in Download Button
  • Automatic flash only if new build has same CM version as installed
  • Bug fixes

As promised, version 1.7.1 of CyanogenROM Downloader removes the need to manually download and flash updates. Users just select when the app should download an update and designate another time for when the app should auto-flash. This process can be followed by the automatic installation of an additional zip, useful for applying a custom kernel. The option to do an automatic backup before the flash is also tucked away in the app's settings.


As is the case with anything concerning CyanogenMod, be pragmatic and cautious. Don't use this new functionality if you rely on your phone as an alarm clock, because there's the chance it could bootloop overnight. CyanogenROM Downloader may make an automatic backup, but that doesn't mean it's completely safe. This is a tool for people who want to live on the edge.

    That's awesome.

  • xsirxx

    How does that work with keeping all of your info on there but not having to wipe before updating?

    • palf91

      Dirty flashes work fine.

      • xsirxx

        Do they really? Ive always done a total wipe so I wouldnt know. BUT if thats the case nowadays then Ill stop wasting my time...

        • Gwanatu

          If you run in to issues always try a clean flash, otherwise dirty flashes are usually fine. I've kept my wife's Nexus 4 on CM10.1 nightlies for months without doing a clean flash and have never run into any issues.

        • shadowdude777

          CM has publicly stated that their ROMs are fine to "dirty flash". I think they might have said that you may need to do a wipe when going between major versions (ie, from CM 10.1 to 10.2), but between just daily nightlies, they've said there's no need. Don't wipe anything, just install the newest nightly zip file and reboot.

          • xsirxx

            That makes sense then. I always backup anyways so i dont have to worry but I also hate when people complain about a rom only to find it was a dirty.

        • palf91

          shadowdude777 below is correct, as long as the major version is the same, it's fine without wiping.

          To be on the safe side, you could wipe cache and dalvik, but that doesn't touch any user generated files like settings or photos.

      • xsirxx

        Also is that strictly for this software or all routes?

        • palf91

          Not every ROM is the same, best to read the documentation on installation. Most devs will post instructions, and for Cyanogenmod, dirty flashing is fine between major releases.

    I don't know about automatically flashing nightlies, to be honest. I'd rather quickly check xda every couple of days to see if there are problems before I actually flash it. The second 10.2 nightly (iirc) had a couple of annoying problems, and reading the forums helped me avoid them.

    I do use CyanDelta for downloading, though.. it's pretty convenient as it only needs to download the files that actually did change between the nightlies (usually 5-20mb) and it can flash it as well and shows you a changelog. Haven't had a single issue with it yet.

  • xsirxx

    How does this stack up against goo.im which I have been using to check for latest...

    • CoreRooted

      GooManager doesn't allow scheduled updates, automatic backups, and adding additional files to the flash.

  • Crazydog

    I still prefer CyanDelta. Not having to download the entire 150+MB updates every day is nice.


    • CoreRooted

      And doesn't do what this app does.

  • Cole Mickens

    Why not use the built in CM Updater?

    Edit: Oh, because I can have it automate flashing my Exchange-Mod zip afterward. Nice.

  • bimsebasse

    CyanogenMod has a built-in updater - what's wrong with that?

    • squiddy20

      If you took even a minute to glance though the article (let alone the title), you'd find that this has many more options than the built-in updater... People like options.

  • Gian Ilac

    Why not use CyanDelta?

    • CoreRooted

      CyanDelta can't automate like this app can.

  • Niels

    I think that would be even more useful if you could automatically flash monthly releases overnight... If you prefer to stay near the edge, but not quite the edge itself and favour a combination of stability and that edge.
