    1. Hi anand

      engineering mode is not solution of your problem.

      if it is hardware problem then contact service center

  16. 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.

  17. 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.

  18. 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?

  19. 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. try it For TV Out in Microma canvas 4 A210 :- Connect OTG Cable with your phone —> HDMI Cable (one side USB male and second side HDMI port) —-> connect with TV

  25. HIII ABHI.

  26. A110 has no HDMI out also not with MHL over USB.
    You have to use the 3,5mm Audio Jack with a special cable that is also available cheap for Nokia Phones (CA-75U) and then you have analog video/audio out.

  31. Abhishek, Hi , was just going through the comments on new to your site.. just wanted to know about the ROM new and have absolutely no idea about anything advanced like
    which is the latest software to a116 and how to update..
    does it fix the volume and gps problems..does it affect the quality of sound..
    how to get back to the original ROm ..will this affect warranty
    and finally if you do a factory reset after trying out the engineering option, will it come back to the original values

    looking forward to your reply ..thanks…. Kumar

    1. hi
      this is official update and no warranty issue so update it .
      after update it will come back to the original values.

      don,t worry after update if you it is not official update then we provide V1 stock Rom of this phone.

    2. Hey thanks for the reply:) . So does it solve the problem of gps and volume. Also is there a custom updating software for Micromax A116 like what LG has . I want it to be as simple as possible. Is rooting required? and please post the link to the latest a116 software..


  32. Hi Abhishek, I have an issue with my Micromax A116. I have to reduce the ear volume for each call as the default ear volume is 100%. Is there anything that we can do to change this default setting? Appreciate your help, Man!!

  36. Hi ABhi,
    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.

  37. 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.

  38. 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.

  39. Hi Abhishek, after upgrading to Jelly bean..headphone music switch buttons are not working anymore….plz suggest solution….

  41. Hi,

    After update to Jelly Bean, my headset button has stopped functioning. Like previously with on lick i can play/pause the music, but now it's not responding. Is there anything i can do in engineermode that will solve this problem?

    1. Hi Abhishek,

      I also have the same issue with the Jelly Bean ROM. This issue is present even in custom ROMS. I flashed SUVI ROM V9 and same issue exists. I reflashed ROM many times, but with no luck. 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.

    2. 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.

  42. Hi Sir,

    Great Information!!
    Can you please help me with the Engineering Mode for XOLO Q800? I am going to buy one today and it will be very nice of you if you could provide the combination for the engineering mode for this Handset.

  43. Hey abhii

    Thanks for ur resolutions even i messed up with my audio settings…. will my phone behave as new once once i change the settings back to default audio settings

    1. Hi Abhishek,

      I'm using SUVI v9 ROM. Everything works fine except that during phone call using the head phone, the other person can not hear me clearly. I need to speak quite loud. I reverted to JMP ROM which I used earlier and I don't face this issue, meaning the head phone is okay and there is some problem with SUVI ROM. Could you please help? Is there any setting I can change? Thanks.

  44. dehey abhishek really stuck up with my phone i have mhl cable hdmi cable but when i conncet to the tv i cannot see see anything.i have neither updated my phone it is the same as it was on the day i buyed it plzz help me out.

    1. so abhishek if i have the jelly bean update will i be able to connect micromax a110 to tv?
      moreover how was the tv display when you connected.ABHISHEK CAN YOU PLEASE UPLOAD A VIDEO "HOW TO CONNECT A110 TO HDMI IN TV".

  45. ya tv has hdmi port i use mhl cable which has microusb one side and male hdmi pin on another side so i directly connect but not working. i think otg is use only for pendrive.

  46. i have mhl cable (micro usb to hdmi) n using cynus T2 jelly bean ROM( for micromax a110) but TV OUT not working plz help. post a screenshot of TV out working

  47. Hello Abhishek,

    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.

  48. 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

  49. 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

  50. 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?

    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?
