How To : Upgrade Micromax A85 to Android 2.3.4 Gingerbread, Step by Step ( iGyaan Version)
Happy March 2012 people, since we promised a stable workable rom for the A85/ cherry Magnum / K Touch k700 with Android 2.3 , we are here to deliver in time.
Before we begin with the update process there are a few things we would like to clear out few important things with you people.
Important Notes
-
We do not take guarantee that this rom will work perfectly and could crash / damage / brick your device. So proceed with your own caution.
- This ROM has been cooked by iGyaan but is majorly based on the official Cherry Magnum 2x update (you will see once you flash your phone)
- We have added bug fixes and tweaks from the Micromax Android 2.2 rom and K-touch K700 Rom to this upgrade.
-
Unfortunately during the update you will loose all data/ apps and most importantly gesture features from the Micromax 2.2 stock rom. So Please Backup Accordingly.
Here are our finding with this rom.
(Based on 3 test units)
- Its very stable = Little or no crashes.
- Audio quality is excellent and networks are solid.
- Battery performance seemed better / depends on usage.
- Very fast and snappy.
Okay now that you are aware of the above lets begin with the process.
