    Have you prepared marshmallow for Karbonn A30?

  • Murtaza


    i have been hunting for a custom rom for SWIPE MTV VOLT phablet. specs are similar to a30. would you think this new rom for a30 would be compatible with swipe

    • Hey Murtaza ! I just searched your device details it has MTK6577 4.1 so this won't work for your device. But, i think ROMS of Karbonn A27+ might work on your Swipe MTV Volt as they both have exactly same specs. Checkout all the ROMS for A27+ here : A27+ ROM List

    I enjoyed your custom rom, but facing a peculiar issue and unable to use my phone any longer.
    I did a factory reset through setting menu, it rebooted trying to delete/erase data, android man appear and after few seconds it boots back and tried to erase the data with android man logo. This bootloop is happening for hours together. I am unable to goto CM recovery using volume down + power buttons or volume up + power buttons or volume up + volume down + power buttons.
    Volume down + power button leads to a Chinese menu, which i guess is testing screen.
    I am unable to go to CM recovery. Please help.

  • Vishal Gajul

    We usually dont get CWM for Karbonn A 30 so use MTK droid tools carefully….I used MTK droid tools so use it carefully or it might brick your phone…!!!!!

  • Vishal Gajul

    If you want to install this rom : READ BELOW ( i did this )
    1) Have your stock rom backup or full stock rom
    2) Get CWM recovery ( to make it easy , download MTK droid tools and read the process of flashing CWM carefully!!!!!!!! on the website….find it..
    3) After flashing CWM , copy the given rom in sd card and boot in recovery mode.

    Follow these carefully !!!! { Keep your phone connected to its charger } for safety .
    1) Wipe cache
    2) Go to advanced and wipe dalvick cache.
    3) Then select wipe data/factory reset option.
    4) Then, select install zip from sd card
    5) Select choose zip from sd card.
    6) Select the given roms location and select it…
    7) After that wait for some time.
    8) Wipe cache and dalvick cache again.
    9) Done !!!!
    { remember in CWM the side button is for select and volume button is to move up and down } this rom might have camera problem so keep your stock rom ready.

    how to install this

  • Anonymous

    Could you please fix the bluetooth range problem,its very short(20-25cm with stereo headset) other wise everything else is good.

    • I'll try to fix this but cannot assure you 100% result as Bluetooth range depends on kernel code.

  • Vishal Gajul

    first of all I THINK THIS IS A BUG :
    1) There is no camera apk in system/app.
    2) Still its showing the camera app in menu.
    3) It cannot be uninstalled because it is not bieng showed in any kind of uninstaller.
    4) I tried a person's flashable camera zip file which i got from a website.
    5) It was for 4.2.2 android but still my camera was not working.
    6) But with that flash there became two camera app and two galery apps.
    7) I have my stock roms camera apk but i dont know how to flash it.????
    8) My camera works fine with stock rom.
    9) I dont want to switch to stock rom again.!!!!
    10) Now how can i fix this????

    • Sorry for this Camera bug. I will try to make a Camera.apk patch of stock rom.

  • Vishal Gajul

    I installed your custom rom and my camera is not working.
    it shows black screen and says " could not connect to camera "..
    i cannot uninstall that camera app because it is not showing in titanium backup….HOW CAN I FIX THIS????
    WHat shoul i do …..!!!!!
    i am waiting from 2 months….for solution?????

    • To remove the Camera.apk Install ES File Explorer. Grant root access to ES File explorer. Open System & Goto App and delete the Camera.apk. Use any third party camera.apk 😀 Hope this helps.

    what is he talking about camera apk..????

  • i found 2 roms for karbon A30 one is this one on the page and other one is MIUI which one is best please let me know

    • According to me both are best& Stable but MIUI would be a better option as its too boring to use the Stock Android look. I think you should Go for MIUI. Hope this helps. Do leave your feedback/Suggestions. Thanks for visiting !

  • There is no camera apk in app folder. can i flash it on Karbonn A30?

  • Link is not working
