Created attachment 8503225 [details] download_flame.log.3.txt I could not figure out which component. I sometimes get a message saying that the update failed to download (it shows on the screen after a reboot) - "There was an error while downloading the updates". However, what I see most is that after the unzipping update stage finishes the state of that update goes back to say that I can download an update. I have attached a logcat in hopes that it can help figure this out. I'm on 2.10.0-prerelease, 34.0a2, 201410060000205, update channel aurora.
Please provide |adb shell df| output, I feel it's just a free space issue.

I think the minimum we could fix in here is to not download a new update without checking remaining free space under /system. There's no need to get us into an infinite loop and we could notify the user how to proceed (e.g. file a bug in X and attach Y).
I don't know why I had /system/media , however, after deleting it I got close to 100MB free space on /system  and managed to update. I also pasted the output of a flame that was flashed yesterday .  armenzg-thinkpad buildbot-configs hg:[production!] $ adb shell ls -al /system/media drwxr-xr-x root root 2014-09-04 03:53 audio -rw-r--r-- root root 9835252 2014-09-04 03:53 bootanimation.zip root@flame:/system/media # ls audio bootanimation.zip root@flame:/system/media # ls audio/ alarms notifications ringtones ui  armenzg-thinkpad buildbot-configs hg:[production!] $ adb shell df /system Filesystem Size Used Free Blksize /system 354.2M 254.9M 99.2M 4096  flash@FlashStation50:~$ adb shell du -d 1 /system 8 /system/lost+found 175360 /system/b2g 9896 /system/bin 5752 /system/etc 57664 /system/fonts 51696 /system/lib 12672 /system/tts 38720 /system/usr 90168 /system/vendor 442024 /system
OK, if the free space in /system is the issue, it's a dupe of bug 1073399. Thanks for the detailed data!
