How to fix the partial wakelock problem on CyanogenMod 11 with Google Play Services and OTA updates

For me only SystemUpdateService$SecretCodeReceiver had to be disabled. All other activities, receivers and services with a name starting with "SystemUpdate" were already disabled. I used ADB + "pm disable" to disable this one component.
Here is a list of commands to disable all SystemUpdate "stuff" via ADB (of course it requires a rooted phone with some sort of "su" installed):

How to grep through (aka. find) binary files looking for a byte sequence (aka. pattern match)

Here's my approach using more or less standard Unix/Linux tools:
find . -type f -exec fgrep -aqs $'\x3c\x3f\x70' '{}' \; -print

If your shell does not support the $'\xHH' notation (eg. standard POSIX shell does not, but bash and zsh do), then you can always fall back to echo's octal representation (although it's a bit uncomfortable since most hexeditors and viewers support the hexadecimal format):
patt="$(/bin/echo '\074\077\160')"
find . -type f -exec fgrep -aqs "$patt" '{}' \; -print

iStat Pro Widget External IP Fix

Open the $HOME/Library/Widgets/iStat Pro.wdgt/scripts/core.js script in a text editor, find the getExtIP() function and replace the following line:
ipURL = ''+new Date().getTime();

with this (or a similiar "what's my ip" service URL):
ipURL = ''+new Date().getTime();

And the following:
if(extIP.length < 20 && ipConnection.status == 200 && extIP.match(/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/)){

With these:
ip_regex = "\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}";
if(extIP.length < 100000 && ipConnection.status == 200 && extIP.match(new RegExp(ip_regex))){
    extIP = extIP.replace(new RegExp("^(.*[^\\d])?(" + ip_regex + ")([^\\d].*)?$"), "$2");

This patch lets you use quite many "what's my IP" services since the the script will take the first IP looking string from the result of the HTTP request.
