My Galaxy S2 build.prop tweaks

Justyn — Sat, 14 Apr 2012 02:59:47 +0000

I’m currently running Cyanogenmod9 on my Galaxy S2 on Telstra. It runs beautifully and I am loving ICS and all the hard work that the CM devs put into their ROM’s. What I’ve done though is created a local.prop file inside /data/ (I know the title says build.prop) but I decided on local.prop since flashing new nightly builds of CM9 I don’t lose any of the settings since they’re in /data/.

I figured I would post it here not only for my future reference but also for anyone else that wanted to copy some of the settings. Once changed, wipe cache and dalvik-cache and reboot. If you do however break your phone, I will not be held responsible.

Calibrate Galaxy S2 Battery

Justyn — Fri, 23 Mar 2012 09:47:26 +0000

So I’ve flashed a couple different ROM’s on my Galaxy S2 and figured I should re-calibrate the battery. I found this thread over on XDA about calibrating the battery, and thought I would post it here (for personal reference) and also for anyone else interested. All props go to ram3n at XDA.

Unlike HTC devices, battery calibration doesn’t apply to our devices. Google MAX17040 for more info – while our fuel gauge chip (MAX17042) does have advanced features that would require calibration if used, those features are not yet enabled and it basically behaves identically to a 17040. Maxim specifically designs their fuel gauge chips to not require special calibration procedures.

So, here are the steps to calibrating the battery for the Galaxy S2.

1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug.
4. Pull out the battery.
5. Wait for 3 – 5 minutes (take this opportunity to clean internals).
6. Put the battery back in.
7. Turn on the phone.

Once you have completed this, do a full cycle (let battery run down to roughly 5% then fully charge).

Samsung Galaxy S2 modem test

Justyn — Sat, 03 Mar 2012 01:28:47 +0000

I have a Samsung Galaxy S2 (GT-I9100T), which is rooted and running CyanogenMod 7 nightly. It’s a Telstra branded modem so it shipped with the DVKF2 modem. Since it is rooted, it is easy to test different modems by flashing them through ClockWorkMod.

I decided to test a couple of the different modems using the SpeedTest application on the Brisbane server. I did 3 tests with each of the different modems and then made an average of the results. Each test was a minute apart. I thought I might post the results here for personal reference. I found out that the modem that wasn’t made for the Telstra network performed worse.

The following results are all averages of the 3 tests. If you like I can update the post with results of each of the 3 tests but figured it may be irrelevant.

As you can see from the results, XXKI3 had faster download and upload, with a little bit higher ping than XXKG2, so I opted to use that modem. So far it’s been working fine and have had no issues. If you’ve found another modem that you’ve tested, and is flashable via CWM please comment a link to the modem so I can test it and add it to my Dropbox folder.

I’ve placed a copy of all the modems on my Dropbox for you to download and test, they are all flashable via CWM. If you destroy your Galaxy S2 though, I will not be held responsible. You have been warned.

Import Google Contacts to iCloud easily

Justyn — Sat, 19 Nov 2011 22:43:58 +0000

Since updating to iOS 5 I figured I would give the whole iCould thing a go for my contacts, calendar and mail. The only problem here was that exporting my Google Contacts and importing the into iCloud was that everything I read said I need to use iCal / Address Book to get them across. I ended up using Sunbird to transfer the Calendar across, and came across these simple instructions in MacRumors forum.

Requirements are Gmail Account and a valid iCloud account (Apple ID)

1. Go to your Google Contacts

2. Click the More > Export

3. Choose the group or all of your contacts you wish to export, whichever you prefer.

4. Choose vCard format and click the Export button.

5. You will now have a contacts.vcf which has been downloaded to your computer. Put it on your desktop if you prefer.

6. Rename contacts.vcf to yournamehere.vcf (example: justyn.vcf)

7. Log in to iCloud.

8. Click Contacts
Important Note: Make sure there are no contacts listed here before importing or this may not work. The page needs to be blank.

9. Drag the .vcf file into the window under All Contacts.
The page will highlight with a blue rectangle when you drag the .vcf onto it. Wait a little bit. (It took about 8 seconds for mine to import. I only have 136 contacts though.)

On your iPhone, go to Settings > iCloud and make sure Contacts is listed as ON.

My Firefox addons

Justyn — Sun, 01 May 2011 06:50:43 +0000

My web browser of choice is Firefox. I have been using it for years and since the upgrade to 4.0 losing the status bar, I thought I might create a post with my Firefox Addons.

Microsoft launches IE6 Countdown

Justyn — Fri, 04 Mar 2011 22:18:17 +0000

Microsoft is monitoring the worlds usage of Internet Explorer 6 by launching a website, IE6 Countdown. Their aim is to try and get the global usage under 1% so more websites can drop Internet Explorer 6 support which will save web developers a lot of work trying to support a web browser that is 10 years old.

At this point in time 12% of the world is using IE6 which is down 9% from last year. China has the highest users of IE6 coming in at 34.5% where Norway and Finland come it at just 0.7%. Australia is only at 3.2% while the US comes in just under at 2.9%.

If you have a website and would like to join the cause you can add a banner to your website asking the user to upgrade to a newer version of Internet Explorer.

Exposé switching on Microsoft Windows

Justyn — Sat, 12 Feb 2011 07:30:24 +0000

One of the things I like about OS X is the exposé styled window switching and I found that was lacking on Windows. I do like how Microsoft have made the alt+tab nicer in Windows 7, but I wanted more. I wanted that OS X style, which can be achieved with a nice utility called Switcher.

I have Switcher set to alt+tab and gives the feel of exposé. I have also installed another small utility called SmallWindows which can set a “hotspot” for your mouse which will activate the exposé style switching too. I have mine set to the top-right corner.

Speed up the iPhone 4

Justyn — Tue, 17 Aug 2010 21:30:50 +0000

I take no responsibility if you destroy your phone, it explodes or your arm falls off.

So you’re probably thinking the iPhone 4 is fast enough already, right? Well if there is any bit of performance you can squeeze out of a device then why not? After doing all this I get around 360MB – 370MB of available memory after a reboot.

First things first, you need to JailBreak which is simple as going to JailBreakMe in Safari on the iPhone. You can either download limera1n or greenpois0n to JailBreak.

What I did was download and run langdel.sh which deletes all language packs except English and Japanese (chmod it to 755 and run as root from MobileTerminal). If you want to remove all except just English, you can run langdelen.sh which is what I did.

Next I deleted the following Launch Daemons from /System/Library/LaunchDaemons/.

- com.apple.Dump* – 2 daemons to disable purpose is to dump the crash for apple evaluation.
- com.apple.Report* – 6 daemons to make reports about what caused the crash/what were running e.t.c.
- com.apple.CrashHouseKeeping.plist – Also deals with crashes.
- com.apple.VoiceOverTouch – Another Voice Control daemon.
- com.apple.aslmanager.plist – This daemon manages system logs.
- com.apple.awd_ice2.plist – Apparently only affects the iPhone 3G and 3GS. It’s not known what its function is on those devices, however, so remove this daemon at your own risk.
- com.apple.datamigrator.plist – Used to transfer contacts from SIM card to phone. iPod touch users can delete this.
- com.apple.marcoagent.plist – Logs errors with WiFi connections (failed to connect).
- com.apple.marco.tcpdump.en0.plist – Logs errors with WiFi connections (failed to connect).
- com.apple.mediaremoted.plist – Backend for AirTunes.
- com.apple.scrod.plist – This daemon deals with Voice Control. If you don’t use Voice Control, you can delete this daemon.
- com.apple.voiced – Yet another Voice Control daemon.
- com.apple.syslogd.plist – Logs system events.
- com.apple.powerlog.plist – This is used to monitor any incompatibilities with 3rd party chargers.
- com.apple.tcpdump.server.plist – This daemon is apparently used to dump traffic on a network. Removing this daemon has no adverse effects on one’s device.
- com.apple.mobile.profile_janitor.plist – This daemon’s function is currently unknown, but removing it has no adverse effects on one’s device.
- com.apple.searchd.plist – Disables Spotlight search if removed. The Spotlight page will still be there, but nothing will show up when you start typing. Disable this daemon if you don’t use Spotlight.
- com.apple.chud.chum.plist – This daemon is thought to relate to Apple’s CHUD (Computer Hardware Understanding Developer) tools. Removing this daemon will have no adverse effects on your device, unless you are a developer.
- com.apple.racoon.plist – Used for Virtual Private Networks. Disable this daemon if you do not use any VPNs.
- com.apple.chud.pilotfish.plist – This daemon is also thought to relate to Apple’s CHUD tools. Removing this daemon will have no adverse effects on your device, unless you are a developer.
- com.apple.AOSNotification.plist – This daemon deals with MobileMe syncing. If you do not use the MobileMe service, you can disable this.
- com.apple.AdminLite.plist – This daemon tries to return control of your device to you if it thinks that you are waiting for a lengthy process to respond. It does this by force-quitting the process, so if you’re tired of your apps crashing and you would rather wait a few seconds for them to finish what they’re doing, disable this daemon.

The next thing I did was edit com.apple.locationd.plist which makes locationd run when needed and not at startup.

Change:

>RunAtLoad>/>

>RunAtLoad>/>

The other thing I did was delete the following files from /System/Library/CoreServices/SpringBoard.app/ which removes shadows from the icons on the SpringBoard.

- FolderShadowBottom.png
- FolderShadowBottom@2x.png
- FolderShadowBottomNotch.png
- FolderShadowBottomNotch@2x.png
- FolderShadowTop.png
- FolderShadowTop@2x.png
- FolderShadowTopNotch.png
- FolderShadowTopNotch@2x.png
- WallpaperIconDockShadow.png
- WallpaperIconDockShadow@2x.png
- WallpaperIconDockShadowT.png
- WallpaperIconShadow.png
- WallpaperIconShadow@2x.png
- WallpaperIconShadowT.png

Another thing I have done is in /System/Library/Frameworks/UIKit.framework/ I deleted all the Keyboard*.plist except for Keyboard-default.plist, Keyboard-en.plist and Keyboard-en_AU.plist. You’re setup may vary though. I also deleted Keyboard-Emoji.artwork and Keyboard-Emoji@2x.artwork since I don’t use Emoji.
