Tutorial: How to upgrade Huawei Ascend from Android 2.1 OS to 2.3
How to get Android 2.3 Operating System(OS) on your Huawei Ascend (For Newbies)
Ok, to start things off, You need to move all of the files that you downloaded to your phone’s SD Card, you will also need a Application Installer, You can download one from the android marketplace for free, there’s tons of them. “AppInstaller” is the one that I personally use.
1)First you must root the phone by installing the Z4Root file. Open your application installer and find Z4Root where ever you placed it onto your SD Card, install the Z4Root. The phone will restart on its own. The phone is now rooted.
2)Next you need to download clockwork recovery from the android marketplace. There is a Free version and a Paid version. The free version works just fine
. After downloading the app, open it and under the 2nd tab of the app choose the reboot into recovery option.
3)The phone will restart itself and a black screen with blue/green text will appear, it is recommended to create a backup before installing anything new. Next, Choose the “wipe data/factory reset” option and click yes. Then choose the “wipe cache partition” option and click yes again. Lastly, click the “advanced” option then scroll down to “wipe Dalvik Cache” and choose yes again.
4)Once you have wiped the three files, choose the “Install From Zip” option, then the “choose Zip from SD Card” option. (You should have the Android 2.3, gapps and Metro backup Files on your zip already, If not, put the two files onto your SD card then repeat the last step). Then scroll down to the “Cm7-Ascend-05142011” option, the new operating system will now be installed onto your phone.
5)After that, choose the “MetrOFF.v1.1-MMS-[GB]-[CM_AOSP]” option. This fixes a bug that caused users to not send multimedia messages properly.
6)Now choose the “gapps-gb-20110307-signed-1.zip”, this installs all of the google apps onto your phone
6)After installing the Gapps file, choose the “reboot system now” option. Your phone now has Android 2.3 Operating system!
