Android 1.5 Cupcake Update Now Available For Android Dev Phones

Owners of the Android developer phone can now download and install the latest Android 1.5 ‘Cupcake‘ update on to their handsets.

The Official HTC website has been updated to offer instructions on how users can flash their Android Dev Phones with a factory Android platform system image and associated radio images.

With these system image files, Android dev phone users can:

  • Keep their Dev Phone up to date with the latest Android system images
  • Test their application on multiple Android platform versions, to ensure compatibility
  • Restore a corrupted device to a factory state

The Android 1.5 radio image, system image, and recovery image can all be downloaded here

    Anyone have success installing this update on their T-mobile G1?

  • Kitsunisan

    I’d be interested in seeing if someone can mod this for use on a standard G1. I know everyone is supposed to be getting it within the next month, but still, it would be great to play with it now.

    This is easy to do just root your phone and install the dev software not that hard also I’ve been using Cupcake for a while although the framework is a little outdated still wouldn’t be that much of a difference but I’ll install it later and check it out.

    worked fine on my dev phone g1

    Android 1.5 (cupcake) feels great; speedier on actions, but lags when having a few apps running…
    But more important: I LOST root access to my Android Dev Phone… Anyone knows how to get root access back?

    thanx heaps :)

  • Stephen

    Ditto here Sameer. I LOST root access to my Android Dev Phone too. Any help would be greatly appreciated.

  • ARMS

    Wow update to cupcake and lose root access! F you Google I thought this phone was a POS now I know it is. And I have a google supplied Android Dev 1. I’m gonna go throw this thing at Sergey’s head

  • Stephen

    I was unable to get root back for the image push from T-Mobile. But I was successful in getting root back for the dev phone by installing the HTC image from

    and then applying the commands from

    “using adb as su”

    mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
    cd /system/bin
    cat sh > su
    chmod 4755 su

    I reimaged from HTC since the image pushed from T-Mobile kept puking on me when I tried to use su under adb.

    bleh i installed cupcake but now the phone says i have the icon for missing sim card in the notification bar all the time and it says my phone has no # when i view about my phone -_-

  • Beth

    Does anybody still have the 1.5 Recovery image supposedly linked to here: ??

    I can download the 1.5 radio image, but when I try to get either the 1.5 system image or the 1.5 recovery image I just get the License agreement and then get redirected back to the same support web page. Help!

  • Beth

    Never mind… IE works, problem apparently only with Firefox (which I used successfully to download the radio image).

  • austin

    i “upgraded” my Retail version G1 to a devphone 1.5 with this NO problems. it just takes a few steps. all f the software and instructions can be found on the HTC website and the XDA forums. good luck

  • Skythe

    Just to add on a few commands to what stephen said:

    (From a windows’ cmd, with adb setup with PATH set, etc)

    adb shell
    mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
    cd /system/bin
    cat sh > su
    chmod 4755 su


    Thanks for this guys, I was a bit baffled as to why my dev phone which i upgraded from 1.0 to 1.5 did not have root!
