Fixing up your Android OTA file

If you’ve deleted some apps (e.g. using TitaniumBackup) and have a custom recovery, but you still want to apply an OTA, here’s what you can do:

unzip the OTA file (into a directory named “n”)

Run some sed commands:

FILE=n/META-INF/com/google/android/updater-script cp $FILE t sed -i '/apply_patch_check.*EmailGoogle/d;/apply_patch.*EmailGoogle/,+2d' $FILE sed -i '/apply_patch_check.*PlusOne/d;/apply_patch.*PlusOne/,+2d' $FILE sed -i '/apply_patch_check.*Gmail/d;/apply_patch.*Gmail/,+2d' $FILE diff -u t $FILE rm n/recovery/etc/install-recovery.sh cd n zip -r ../o3.zip .

and then use your custom recovery (e.g. clockwork) to install the zip.

Hi Devrandom, thanks for the post! I have a question, which I posted here: http://stackoverflow.com/questions/20162112/sed-syntax-explanation-android-updater-script . Would be great if you could have a look at it. :)
