Android Lollipop 5.1 factory images are now ready for download

by: Matthew BensonMarch 9, 2015

Lollipop statue Android Google straight on

Just a few hours ago, Android 5.1 became official, though it had been spotted running on Android One devices earlier this year. The new build includes three main features, multiple-SIM card support (a staple for many Asian devices), device protection, and HD voice calling along with bug fixes and the likes.

While there are no concrete details as to when the update will arrive OTA, Google has thankfully begun to post the factory images. Those who know what to do need only click on the link below, find their device, get their download on, and patch away. For those who aren’t quite sure what to do with a factory image, we have a guide that should help you along the way. Keep in mind that the guide was written for Android 5.0 Lollipop, but the same steps apply. Be aware that making a mistake with the process may brick your device, so please do so at your own risk.

The factory images are available directly from Google and can be accessed by clicking this link.

For reference, the images for the following devices are currently provided (the list will be updated as more devices are added):

  • Nexus 5
  • Nexus 7 2012 (Wifi)
  • Nexus 10

The following are currently unavailable:

  • Nexus 4 – Pending Release
  • Nexus 6 – Pending Release
  • Nexus 7 2012 (Mobile) – Pending Release
  • Nexus 7 2013 (Wifi) – Pending Release
  • Nexus 7 2013 (Mobile) – Pending Release
  • Nexus 9 (Wifi) – Pending Release
  • Nexus 9 (LTE) – Pending Release
  • Nexus Player – Pending Release

Anyone flash Android 5.1 to your Nexus yet? If so, how is the experience treating you, notice any improvements so far?

  • JoeBear

    Yay! Hope it fixes the audio bug.

    • Tobias Wikström

      This is highest on my wish list.

    • Cowen K. Gittens

      On which device?

      • JoeBear

        Nexus 10. Not sure about other devices but its common to have to reboot to get audio working with Lollipop.

  • crutchcorn

    Here’s to hoping Android being more stable than ever!

  • fatspirit

    Waiting for OTA now (:

  • mikegonzalez2k

    Running it right now on my Nexus 10. Seems stable so far.

    • KK

      Finally stable or more stable than 5.0.2 but still has issues?

      • mikegonzalez2k

        It’s been 24 hours and I have yet to see any issues. Crossing fingers…

  • jalado

    Still too early to tell. I hope the memory issue is fixed. It seems to hover around 400-500mb I’ll see what happens in a couple days.

  • Andrew Tan

    Nexus 6 is buggy, waiting on release fix.

  • Kirkilis Petros

    Just finished flashing it to my gf’s nexus 5. Everything seems to work fine, although there is no silent mode option, yet again…

    • RockAndRock

      Really ? How ? I’ve a error message “error: cannot load ‘system.img'” :(

      • Derek Wong

        Manually extract the IMG files from the zip file and use coand prompt to flash them into your phone.

        • RockAndRock

          Hi thank you for replying. It’s done, but this error message still here :/

          • KingofPing

            Running flash-all doesn’t seem to work for a lot of folks – even on the command line. You need to flash the system image by itself, manually.

            Flash everything but userdata and system manually, then flash system:
            fastboot flash system system.img

            Then userdata:
            fastboot flash userdata userdata.img

            This worked for me; hope it helps.

          • RockAndRock

            Hi thank your for your help ! But i’ve the system.img error message :/

          • Boris

            me too… :(

          • J. Rafael Rodriguez

            did you fix it? how?

          • RockAndRock

            Yes I’ve flashed the 5.0.1 image :/

  • ahmedt7866

    Anyone notice better battery life on any devices?

    • fatspirit

      In less than a day? (:

  • Cowen K. Gittens

    I’ll just wait for someone to say it’s stable enough then I’ll download it

  • yardie

    Have to say battery life has seen an improvement on my nexus 5 so far. Forbthe memory leak I’ll have to give it a week to see.

  • Jim Wilt

    Android Lollipop is proof that Google IS NOT the next Microsoft as so few hardware providers of recent devices (phone & tablet) have any path to upgrade to it. Granted, hardware providers have no reason (incentive) to promote an upgrade.

  • markelite

    I thought Nexus 6 is going to be one of the first nexus devices to get 5.1 update.
