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 

  1. We do not take guarantee that this rom will work perfectly and could crash / damage / brick your device. So proceed with your own caution.


  2. 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)
  3. We have added bug fixes and tweaks from the Micromax Android 2.2 rom and K-touch K700 Rom to this upgrade.

     

  4. 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)

  1. Its very stable = Little or no crashes.
  2. Audio quality is excellent and networks are solid.
  3. Battery performance seemed better / depends on usage.
  4. Very fast and snappy.

 

Okay now that you are aware of the above lets begin with the process.

    I have upgraded Micromax A85 to 2.3.4. Its successfully done with no obstacles. But i am facing a problem… Whenever i try to check balance through service code… Network goes immediately and “Connection problem or invalid MMI code” error displays on screen.
    If i try to call someone… after calling when i try to disconnect call.. again network goes immediately. 
    I am not able to use Hotspot… no data conenction… 
    NO doubt Battery backup becomes brilliant now as compare to previous version. But please help me to troubleshoot my existing problems.

    I have bought an Micromax A85 used phone which already had Gingerbread 2.3.4 installed.I have severe issue with the network and battery, I do not know if this phone was upgraded with the igyaan bundle. Do you think using igyaan bundle will help me solve the above issues.
          Please guide me I am a little novice in this department,will require your full help.   Secondly I am trying to use Mobilego software for copying the phones content to the PC but the software keeps on telling me to connect the phone via USB even after it is connected. Can you help me for this as well.    
    In my Laptop the Magnum 2x shows a exclamation mark in the Device Manager while in my desktop, the drivers are installed properly there is no exclamation mark but the phone does not connect to Mobilego neither does it shows up in the Windows Explorer. 
         If there is a driver issue, please provide me with a proper driver.    Actually I had a budget crunch but wanted to have a dual core i.e why I went for this used phone but the network keeps on fluctuating like a roller coaster even while the phone is stationary.  Lastly is there a upgrade above 2.3.4 or is it expected.  
    Awaiting your help
    Thanks
