[Android Q&A, Help & Troubleshooting] BlueFlame:
Tips and tricks. (or something...)

Get adb working (needed for all the other tricks down below):

1. Download the Google development tools (sdk) here and install them on your computer. I assume you have windows 7 installed during the rest of this tutorial.

2. Connect your device to your computer and make sure it is installed correctly.

a. Connect your device while its powered on via USB to your pc.

b. Go to Start, right click "My Computer" and select "Properties". Click "Device Manager".

c. Right click the Android device with the exclamation mark and select "Update Driver Software...".

d. Select "Browse my computer for driver software".

e. Select "Let me pick from a list of device drivers on my computer".

f. Keep "Show All Devices" selected and click Next.

g. Click "Have Disk..." and click "Browse..."

h. You can find the drivers in the "SDKInstallLocation"\sdk\extras\google\usb_driver directory and click OK. Replace SDKInstallLocation with the location that you selected during installation of the SDK.

i. Select the "Android ADB Interface" driver from the list and click Next.

j. Confirm installation by clicking on "Yes". Sometimes you also have to click on "Install" if a screen pops up to ask you again if you really want to install the driver...

k. Click "Close".

To use it:

Open a command prompt (in search type "cmd" followed by ENTER) and go to the following directory ""SDKInstallLocation"\sdk\platform-tools".

If you want a backup of your tablets system directory (highly recommended!) use:

"adb pull /system C:\system"

where C:\system is the target location on your local computer where you want the backup of the system directory.

Remove the update package (this doesn't work for updating the tablet, so, useless.)

adb remount

adb shell

cd system/app

rm Update.apk

exit

Remove the unwanted apps (dragonfire.apk etc)

adb remount

adb shell

cd system/preinstall

rm *

exit

If you would like to have your tablet in the correct time zone after factory reset, you will have to adjust the build.prop file.

First you need to get it to your pc so you can edit it:

in the command prompt window and at the same location as in the tutorial above type "adb pull /system/build.prop C:\temp\build.prop".

Just in case, make a copy of the build.prop in Windows Explorer so you always have the original file if something goes wrong.

Now you can edit the build.prop, but DON'T EDIT IT WITH THE WINDOWS NOTEPAD! Use Notepad++ or similar to edit the build.prop.

After you made the changes (and be careful here, you could end up with a tablet that does not want to boot up, solution further down below) you have to upload the file back to your tablet.

in the command prompt type:

adb remount

adb push C:\temp\build.prop /system/build.prop

adb shell chmod 644 /system/build.prop

Don't forget the last line! If you do not chmod the file (set the correct permissions) your tablet will not boot up.

Changes in the build.prop:

Time zone:

Default time zone is "persist.sys.timezone=Europe/London"

you can change this to your locale time zone like "persist.sys.timezone=Europe/Amsterdam" (for the netherlands ;))

Search the internet for valid time zones.

Change the default language:

The default language is determined by these two values in the build.prop:

persist.sys.language=en

persist.sys.country=US

For dutch change them to:

persist.sys.language=nl

persist.sys.country=NL

and again, search the internet for valid language values.

Higher brightness after factory reset:

Add the following line to the build.prop file (at the top of the file)

ro.ph.def_brightness=225

You pushed the build.prop without changing the permissions:

No problem. Just connect your booting tablet to the PC, install the driver if its not installed correctly like explained in the tutorial, and then change the rights via adb. It's no problem that it's not fully booted!

in a command prompt in the adb directory:

adb remount

adb shell chmod 644 /system/build.prop

adb reboot

If you pushed a wrong non functioning build.prop, just use this method to push the original build.prop (you know, the copy you made ;)) back to the device (followed by setting the correct permissions of course).

Remove the (in my opinion) irritating boot sound:

adb remount

adb shell

cd system/media

rm boot.wav

exit
