      don't worry take a backup of your phone then reset your phone.

    1. 1st Ans:- No need to root your phone for Engineer code

      2nd Ans : – Enable your debugging and Media Mode

  33. Hello Abhishek,

    Pankaj again…if u remember I had few questions regarding Doodle A111 connectivity with Sony LED TV through USB cable.

    I have two more questions :-

    1st Question : Does Micromax Doodle A111 must be rooted first to open the engineering mode through that *#*#3646633#*#* code ? If not then is there any way to open the engineering mode of A111 Doodle as this code is not working ?

    2nd Question : When I connect another phone like Micromax Canvas 2 to TV through USB cable …then it gives 4 options to selec (1) Mass Storage (2) Media Transfer (3) Charging (4) I think some debugging….and we can easily select Media transfer or Mass Storege …and I can access the SD card folder. However, while connecting Doodle A111 it gives only one option to "ON" or "OFF" the "Mass Storage". Is there any way to get that 4 options in the phone so that I can select the Media Transfer and access the SD Card folder in my Sony LED.

  34. Dear Abhishek I have a MICROMAX A110Q I have tried from the phone dialer *#*#3646633#*#* but Iam unable to locate TV out in the Engineering Mode. Kindly help. I have bought the MHL adapter cable (SONY make) which has a mini USB on one end and HDMI on the other end.

  35. I appreciate the quick response… Abhishek..!!!
    Few more kind questions please…
    When I connect my phone with computer with same steps…I could access SD folders. However, when using same steps to LED TV…not able to see the folder on LED TV. Strange??

    Does OTG works on Doodle A111? if no then is there any apps or way to OTG start working on this phone?

    Further, Micromax Enginerring Code also not working on Doodle A111? Is there any other way to open engineering mode?

    1. Microma not support TV out

      Micromax not provide OTG service

      Micromax Enginerring Code is working Doodle A111

  36. Hey, I am not able to connect my Micromax Doodle A111 with Sony LED. I wanna just access the SD card folder where I have movies saved. So when I connect with USB cable it gives me 2 options —(1) Debugging …I already checked that option …and (2) USB Mass Storage turn "ON" or "OFF". I had tried keeping it "ON" but still no folder shown on LED TV. Does that problem reated with TV Out option in Engenerring Mode? Please reply ASAP…thanks for your help on this

    1. default launcher have 5 page, it is not removable
      if want to delete then use other launcher

  45. A110 has no HDMI out also not with MHL over USB.

    Have u tried tv out with Jelly Bean,Is it working?
    i m going to buy MHL adapter ,what should i do,u will check first and let us know,in JB there is option of tv out (enable/disable) in engineering mode.

  57. Hi,
    Increasing the Loudspeaker volume is cracking the sound. Sound cracks from the Loudspeaker when increasing the max value above 140. The default value is 152, and sound is cracking on this value too, so I reduced the value to 138.
    Please suggest if it is with everyone or only my mobile (A116) has this problem. So that I take it to the Service Center.

  58. Hi
    Is there any option in A116 so that the mobile go to sleep mode but do not lock. I mean it unlock with a touch only and no need to press physical unlock button.

    1. hi kiran with tv we watch move on tv & play game on TV with mobile lots more but it is not clear that micromax a110 tvout is working or not because some people told it is working & same says is not working.

  61. Hi,

    1. no, it is not solve by engineer mode. your phone touch driver not install properly. so re-install Rom via Sp tool

    2. Hi Abhishek,

Please let me know if you have a solution for this issue. This is the only reason I keep going back to the stock ROM. Right now, as I'm typing this I'm flashing the stock ROM after testing the SUVI ROM. Thanks in advance for you help.

    3. No Abhishek, Same problem exists in Cynus T2 ROM as well. I flashed it, tested and went back to stock again. Please help here if you have any solution for this. Thanks in advance.

    I messed with the Audio Setting for Value for both Headset Mode and Loudspeaker Mode.
    Please can someone let me know the default setting for Audio; Headset Mode [Value, Max Vol] and LoudSpeaker Mode [Value].

    Thanks in advance.

  70. if you update with cynus T2 Jelly Bean Rom than you get by default TV out setting in display option

    this best rom for Micomax A110 update now with Stock Rom Cynus T2 Jelly Bean 4.1.1

  71. currently on suvi ROM v3 when I enter into engineer mode TV out option not showing there I have mhl cable n HDMI cable. please post TV out patch so that I can use TV out on suvi ROM

    1. it is not only suvi ROM. it is basically Cynus T2 Rom Default Feature.

      Suvi Rom is cyuns T2 modified Rom ok

      best ROM is Stock ROM
      V2 and Cyuns T2 Jelly Bean

  72. My a110 phone came with v2 ROM. I flashed with Mobistel cynes T2 JB. I like the updates but is there any way to go back to original rom as it was supplied with phone?

  73. OTG Cable —> HDMI Cable —-> TV Cable

    HDMI Cable:- one side micro usb to HDMI

    TV Cable:- one side HDMI Female to Three pin (Audio & Video)

    1. I think OTG cable is just micro-usb to USB(i use it to connect keyboard, pendrive, mouse, etc to phone), so its not in the scene. MHL cables have one end micro usb, other end HDMI Female socket. My TV already have a cable out with male HDMI. So i think one end of MHL cable(micro-usb) goes into phone, other end( HDMI Female ) should be plugged into Cable out in my tv ( HDMI male).

      My phone is rooted but it have stock rom. The number you told in this post i tried and it works. I saw an option TV out. I think i have v2 rom as stock because i have two internal memories(1gb, 1.45gb). So will i have to flash another rom for it to work?

  74. Hi i want to connect my Micromax a110 to my TV which supports HDMI. Will a micro usb to HDMI cable(MHL cable) work? my phone is rooted.


    1. Engineering mode —> Audio —> Loud Speaker Mode —–> default 128 customize 0-160 change & enjoy

      good day

  76. no, when you connect your phone to TV then you enable & see this setting in display setting
