Manually flashing an OTA-update

I recently acquired a second-hand HTC One X. A week or two back HTC decided to release the JellyBean update for the phone, all was well. Yesterday, another update was sighted on XDA, and since it seems like this one gives better battery life, I didn’t feel like waiting another 3-5 weeks before it became available in my country, so I searched on how to manually flash an OTA.

As always, this procedure comes with no guarantees it will work for you. It might as well decide to eat your cat, or turn your blood into liquid metal (if you don’t have a cat).

Copying over your wifi access points on Android

In case you have just bought a new phone, rooted it, and want to copy over all your wifi access points, there are a few options:

  • Use the synchronisation to Google to have them keep a backup. Not my favourite, since it tends to restore just a bit too much (like all the apps you already removed before)
  • Use a tool like Titanium Backup, but I’ve noticed that this doesn’t always work between phones. On the same one, sure.
  • Manually copy them over. This is the way I usually go, and it works well.

First, copy the original files over: (do this for both phones)

  1. Plug your phone via USB, enable USB debugging in the setting (developer options) and make sure you have the Android SDK installed on your computer
  2. Disable wifi on your phone. Really. Just do it.
  3. open a shell to your phone, and copy the wpa_supplicant.conf file to your SD:
    adb shell
    cd /data/misc/wifi
    cp wpa_supplicant.conf /mnt/sdcard

  4. Pull the file to your computer somewhere:
    adb pull /mnt/sdcard/wpa_supplicant.conf /tmp/wpa_supplicant.old

Repeat this for the new phone, but in the last step, you should pull it to /tmp/

Now, edit the /tmp/wpa_supplicant.old file, and remove everything that doesn’t read



Next, we want to add this to the new file. Easy peasy: cat /tmp/wpa_supplicant.old >> /tmp/

The last thing to do is put the new file on the new phone, and reset it’s permissions:
adb push /tmp/ /mnt/sdcard/wpa_supplicant.conf
adb shell
cd /data/misc/wifi
cp wpa_supplicant.conf wpa_supplicant.conf.backup
mv /mnt/sdcard/wpa_supplicant.conf .
chown system.wifi wpa_supplicant.conf

And you’re good to go. Rebooting your phone might not be necessary, but it’s recommended.

S-OFF and Jellybean on the HTC Desire HD (Ace)

I acquired a secondhand HTC Desire HD, a nice phone (albeit a bit heavy). Comes with Android 2.3 (Gingerbread) and Sense. I’m personally not much of a Sense fan, and I wanted to move to a newer Android release, so I looked around on how to achieve S-OFF.

In the end, it’s fairly easy, thanks to the Advanced Ace Hack Kit (AAHK now for short).

Requirements for the adventure:

First, read the “effen manual” that comes with the AAHK. Find the code, and once you’re in the menu, pick option 1 – “Hack Ace”.
Wait a bit.
See the phone reboot some.
Wait some more.
*poof* you’re now S-OFF!

The next thing I did was flash a new recovery (I’m a big fan of 4Ext Recovery), and after that downloaded the radio and the lastest version of JellyTime and the accompanying Google Apps and flashed those. A reboot later: JellyBean on the HTC Desire HD!

Reset android lockscreen to slide

You’ve just reconfigured the security lockscreen settings on your (rooted) android phone, and then forgotten eg. the PIN code to unlock it? It happened to me yesterday.

Luckely(?) there’s an easy way around it, if you have adb activated:

Connect your phone to your computer, and do this:

adb shell
rm /data/system/locksettings.db*

This will basically delete the lockscreen settings database, which will make it revert to the default setting (slide to unlock).

This does mean that if you have adb enabled by default on your phone, the lockscreen is defeated very easily. So don’t depend on it with your life.
