[Android Software/Hacking General [Developers Only]] Cricket Ryan:
Now Available - Cricket Zio 2.2 Android Upgrade

Hi All,

My name is Ryan and I work on behalf of Cricket. As many have notice, Android 2.2 is Here! We're excited to let you know that the Android 2.2 upgrade for the Sanyo Zio (1.6 OS) by Kyocera is now available.

The upgrade will be available in Cricket company-owned and premier dealer retail stores where it will take about ten minutes to complete. You can also upgrade your phone over Wi-Fi which is expected to take between 30 and 60 minutes.

How to Upgrade Zio

The Android 2.2 OS upgrade must be downloaded over Wi-Fi and consists of three individual packages. Each package will first download and then install. Installation and download times will vary depending on your Wi-Fi connection and data speeds. The average time for download and installation of the first and second packages is 5 - 10 minutes each, and 20 – 30 minutes for the third package. There will be a power cycle after each of these packages has installed. You may be required to re-establish a Wi-Fi connection after the power cycle.

Please Note: The server can only handle so many simultaneous upgrades. If you get the message ‘no download available’ on or after February 28th, it’s likely that the server is busy. Please try again in 20-30 minutes or during off peak hours (i.e. after 9 pm).

Before you start the upgrade, make sure you’re phone is fully charged and we recommend you set your device timeout setting to ‘never timeout.’

To start the upgrade - Establishing a Wi-Fi Connection - Go to Menu > Settings > About Phone > System Update > Select “Check for update”

Q: I am attempting to download the Zio 2.2 upgrade over Wi-Fi, but I’m getting the error ‘no download available,’ what does this mean?

A: If you’re attempting to download the upgrade on or after February 28th and receive the message ‘no download available,’ the server hosting the upgrade software is busy. Try again in 20-30 minutes, or during typically slow times (i.e. after 9 pm), or you can take your Zio to a Cricket store and we’ll be happy to upgrade your device for you.

Q: Can I use my phone while the new software is downloading?

A: You can, for the most part; there are only a few times during the upgrade that the device will not be usable (this is noted in the upgrade instructions). It is recommended, for the most efficient upgrade experience, that you refrain from using your device to make / accept calls, send messages, or for web access while the upgrade is in process. Doing these things while the download is taking place in the background won’t harm the device, but download speeds will be slower.

Q: What happens if I lose my Wi-Fi connection in the middle of the upgrade?

A: Reconnect to Wi-Fi and then go to Settings > About Phone > System Update > Check for Update to finish the upgrade. Otherwise, your device will automatically retry the download in 2 weeks.

Q: If I need to Factory Data Reset later, will my Zio revert to an older version of Android?

A: No, a Factory Data Reset will remove any installed third-party apps and all Google account information. It will not affect data on the microSD card, or change the Android version in any way.
