The Jelly Bean OS for Micromax A110 is out and there is nothing official about it. In other words it’s the Mobistel Jelly Bean ROM and nothing to do with Micromax. Updating to any 3rd party ROM will void your warrant and there is a risk, if you can take.

One again, proceed at your risk though the chances of failure are less, but you never know. If you are willing to take the risk and upgrade your Micromax A110 to Jelly Bean OS, read on.

The process is much simpler than as seen with the V2 ROM upgrade. You need to download the Jelly Bean ROM from here remember this is not the official Micromax JB ROM.

Once you download the file that is over 200 MB, place the ZIP file on the internal storage or the external storage, I prefer the internal storage, make sure there is plenty of space on the internal storage cause the 1.5GB is allocated for phone storage and 1.48GB for apps.

How To install Jelly Bean OS on Micromax A110 (Please read the full article before applying the update).

  • Make sure the battery level is over 60%.
  • Copy the zip file on to the internal SD card.
  • Shut down the handset.
  • Press volume +, volume – and power button simultaneously and keep pressing until you see two options.
  • Use the up or the + volume button to enter recovery mode.
  • Now select apply update from SD card and choose the CynusT2JellyBean_V15.01 file. For moving up and down use volume buttons and for selection, use the context button or the left square dedicated button.
  • The update will start, will take few minutes. Then restart the phone and all the apps on the phone will be optimized for the JB OS.

Though most or all of your apps will work, but better take backup of important files & contacts etc. if needed.

After the update

  • Quadrant score = 2586.
  • Antutu Score = 6830.
  • Nenamark2 = 22.9fps.
  • Internal storage for apps = 1.2GB (332MB used).
  • RAM 176MB free (311 MB used).
  • 1.05GB as phone storage.

One of my SIM card did not work – failed to show the network, I tried another SIM card and that worked. In fact both the SIM’s that worked were  64K SIM. If you are using older SIM card then probably it might not work, better upgraded the SIM or don’t update to Jelly Bean OS.

The performance is good, image quality seems a little better, sound is as it was before. I have just updated, will use the new OS for some time / days and will updated this page as soon as I find any issues or something good about it.

Update : 8th Feb 2013.

There are minor issues with the JB ROM, I would suggest wait for some more time before going in for the update. For me the main issue was that older SIM did not work and when receiving a call the caller name is not showing. I have reverted back to the V2 ROM and will wait for some more updates on XDA. If anyone has successfully installed the ROM with no issues, leave a comment below.

Update : 11 Feb 2012
I tried the new ROM JellyDream and it works great so far and both SIM’s are Working. I already had the V2 rom installed.

  • Download and copy the zip in the internal SD card folder.  (
  • You need CWM recovery its different if you try using the default recovery as on the V2 ROM it will not install.
  • First root the A110 running V2 ROM if you have not done it the easiest method is here
  • Check with root checker app and see if the handset is rooted.
  • Now install CWM details here (skip the root process).
  • Once done you will get an option start phone in CWM mode now follow the steps as on
  • Do clear the cache, data and Dalvik cache before restarting.

Here are some screen shots of the Jelly Bean and as you can see in the image both SIM’s are working.

MMX-A110-JB5 MMX-A110-JB4 MMX-A110-JB3 MMX-A110-JB2 MMX-A110-JB1

I have just started using the Jelly Bean ROM will keep updating here in case I find any issues.

  4. Dear Sir,

    I have a Micromax Canvas-2 A110 smart phone since November – 2012.

    My phone is good but last week in my phone keyboard “P” is not press….so when i msg it type very problems issue for not type of “P”

    SO what problem in my phone ?….

    what can i do ?

    Kindly suggest me ……..

    1. Sam, in settings developer option enable show touches and tap the same place or move finger on the screen to see if the touch is registered. If you are not able to find show touches option, try rotating the phone when using the keyboard and see if the ‘P’ key works. It could be touch issue at specific point and you might want to get it checked at service centre.

    will I be able to play such HD games in low ram?
    please help me should I upgrade or not.
    thank you.

    1. i am playing asphalt heat 7 and other hd games of jelly bean update…
      update without any prob dear…..

    2. Looks like you are keeping your phone “FRRrrrrrrrrressssshhhhhhh”. For you there won’t be any prob with JB.

      How can you have 230mb rom with many apps installed? Hard to believe

  14. Hey gogi,
    I recently bricked my A110 while trying to install the 4.1.2 official micromax approved jellybean rom;.
    Now it’s not starting..
    It’s doesnt even get to the boot screen.
    Just plain black screen when i hold the power button..

    PLEASE help me to unbrick my phone.. please sir

    1. Better to visit service centre..
      you have done some mistake while installing the V3 ROM..
      you do one thing pull out the battery for 2 mins and after inserting hold the power button for 15 seconds…..else visit nearest service centre…tc bye

    2. Hi Abhay, as above said the chances are very less to brick…I had same issue and this is what i did..
      connect your ph with usb and make sure you have installed the phone drivers “MT6577 USB VCOM drivers” (because i didn’t initially). download a Stock v2 ROM and SP flash tool. read the instructions for SP flash tool and I hope it works. Do not try to turn on the phone during the update.

  15. Gogi… We should salute micromax for providing V3 jelly bean 4.1.1 official ROM… No doubt come bit late but is really nice.. The free RAM i checked was 180mb and all other features really are so nice.. The display brightness is same as we saw in V1 ROM which was lacking in V2 and Cynus and other custom ROMS…

  16. Micromax A110 Official JellyBean Launched

    Happy News,

    Jellybean Launched for Micromax A110…

  17. Gogi and all…
    Dear today i played shadowgun HD game on my A110… The experience with new updated Cynus T2 jelly bean is marvellous. It is running so smooth that my lips cant stop to saying this…. Love u micromax a110 but slight less than Mobistel Cynus Germany as they made this phone on top of the world.. Enjoy hd games friends..

  18. I have updated my mmx a110 to jelly bean using cynus t2 rom … Alls fine .. Net fine, both the sims fine, perfect actually. Only Need to root it please help how.. And i have nearly tried all the ics roms by xda developers… Only few worked like indi rom.

    New software update statement

    4) Press the “power button” and “The mean volume button” together at the same time and “The upper volume key” to access the recovery mode.

    → Reset Please go to Menu → Settings → Backup & reset → Factory data reset → Delete all phone

      1. @negi…. Cynus is brand phone in Germany like our micromax in india so it is not a custom rom which often have bugs. This new jelly bean updated rom of cynus is better among all and hopefully u will not find issues like sim coverage internet problems Google voice as found in almost all custom roms. Negi plz confirm me wich sim u r using..

    1. its showing signature verification failed, installation aborted. what to do now?

      1. @ amit u need atleast v2 version of micromax or cynus t2 rom to update cynus jelly bean

    2. Hi Imtiyaz Bhai,
      Thanks for the detailed steps. I have done it and it got installed well. But, I am facing the same problem as I faced with the official MMX JB update. After completion of all the steps, again, the IMEI No. is shown as invalid. I am not able to either make or receive calls. However, GPRS is working OK. Can you please suggest how to regain/correct the IMEI problem? Regards.

    3. Sheikh Bhai,

I tryied to find the solutions on web but it is out of my understandings, it says replace the modem.img file but how coz I found the one modem.img file in system but what about the another file in stock v2… again all the sites shows screen shots after the JB installed… they shows setting page having icons in coloured… but after installed JB my icons are as it is…. please provide me solution for starting my internet again….. with easy steps coz I’m not an engineer..

    2. Yea I did…. it is smooth and fast among all ROMS till date. Moreover it is official but brand name is Cygnus Germany despite Microma. Much usable RAM. Will check HD games later and update….
