Preparing your WordPress Upgrade
From time to time you may want to update your WordPress installation to the latest version. You might want to do this because you’ve seen a message at the top of your Dashboard telling you that a new release is available, because you’ve been made aware of some useful new functionality, or because a security fix has been released.
Check Requirements
Whatever the reason for updating, before getting started it is best to check the current minimum requirements page first to make sure that your web host has the required versions of PHP and MySQL. (If you are not sure, then your hosting provider should be able to tell you.)
Take a Backup
The next thing to do is to take a backup of your database. All your posts and Pages are held in the database, so you will need to have a copy of it in case, for whatever reason, you change your mind after upgrading and need to go back. If you are not sure how to backup your database, then complete instructions can be found in the WordPress Backups section of the Codex.
Disable Plugins
The final preperation step is to disable plugins. Now, you don’t have to do this, but every now and again a plugin hasn’t been updated to work with the latest version of WordPress, and causes a problem after the upgrade. So, it’s best to try and avoid that, yes? You can easily disable your plugins by heading to the Manage Plugins page in the Dashboard, changing the “Bulk Actions” pull down menu to “Deactivate” and clicking “Apply”.
Ready to Update
Now that you’ve checked that you’re ready to update, you’ve turned off your plugins and you’ve got your backup, it’s time to get started.
Step 1: Download & unzip the WordPress package from:
- If you will be uploading WordPress to a remote web server, download the WordPress package to your computer with a web browser and unzip the package.
- If you will be using FTP, skip to the next step – uploading files is covered later.
- If you have shell access to your web server, and are comfortable using console-based tools, you may wish to download WordPress directly to your web server using wget (or lynx or another console-based web browser) if you want to avoid FTPing:
- wget http://wordpress.org/latest.tar.gz
- Then unzip the package using:
- tar -xzvf latest.tar.gzThe WordPress package will extract into a folder called wordpress in the same directory that you downloaded latest.tar.gz.
- Delete the old
wp-includes and wp-admin directories on your web host (through your FTP or shell access).
Then, run the following commands to unpack and copy the contents into your web directory.
tar -xzvf latest.tar.gz
sudo cp -R wordpress/* /var/www/
- If you do not have shell access to your web server, or you are not comfortable using console-based tools, you may wish to deploy WordPress directly to your web server using ZipDeploy.
Step 2: Update your installation files
This will update your database to be compatible with the latest code
Visit your main WordPress admin page at /wp-admin. You may be asked to login again. If a database upgrade is necessary at this point, WordPress will detect it and give you a link to a URL like http://example.com/wordpress/wp-admin/upgrade.php. Follow that link and follow the instructions. You should do this as soon as possible after step 1.
That’s it, you’re complete!

It’s here. It’s finally, finally here. After countless rumor-fueled false starts and delays, the Android 2.1 update has finally started rolling out to Verizon Droid owners.
Unfortunately, it’s only been rolled out to around 8,000 Droids at this point — and considering that there are purportedly at least a million of these things floating around, that means the majority of people are still waiting for their update. Are you one of them? Fear not, friend! We’ve got all the details on how to manually update your Droid to the official, Verizon-and-Google-blessed build of Android 2.1.
All in all, it should take you about 10 minutes. There is no “hacking” required – your device doesn’t need to be rooted, overclocked, underpantsed, or what have you. This is the same package you’d be downloading from Verizon (it even comes from Google’s server!), just a whole lot sooner.
Here’s how to do it:
- Download the update package from here. Don’t unzip it! If your browser automatically unzips things (like Safari on Mac, for example), use a different browser. It MUST stay zipped.
- Rename the file from signed-voles-ESE81-from-ESD56.fa406da6.zip to update.zip. If you’re using an OS that doesn’t show the .zip extension, just rename it “update” — otherwise it’ll be called “update.zip.zip” and won’t work.
- Take the microSD card from your phone, plug it into a microSD card reader.
- Drag and drop the “update.zip” file into the main folder (otherwise known as the root folder) of your microSD card. Don’t go looking for a folder called “main” or “root” – we’re referring to the folder on your microSD card that holds all the other folders.
- Turn your Droid off, and put the microSD card back in.
- Hold down the letter “X” on the keyboard. While still holding it, turn your Droid back on. You should see an exclamation point icon appear on your screen.
- Push the volume up button and the camera button at the exact same time. If nothing happens, do it again. When you get to the bootloader screen, you know it worked. (Some folks are reporting that you need to hold the volume up button and then tap the camera button right after. It’s a bit tricky, but it’ll work eventually.)
- Use the d-pad to navigate to the “apply: update.zip” option, and choose the file you just dragged onto your microSD card.
Bam! Download, rename, reboot, hold a button, done. Could it get much simpler? As soon as the upgrade process finishes, you’ll be Android 2.1′d up and ready to go.
Enjoy!
