  1. Sir I’m using canvas a1 which was running on 6.0.1 but unfortunately I lost my software I’m trying to applying from SD card but it say abroad …. Use 6.0.1/MOB31E/3142026: user/ release-key sir give me the link of 6.0.1 / MOB31E plsssss

  2. Reboot into recovery and wipe cache. Still have problem, do a factory reset in recovery (backup data before proceeding). If problem still persist reinstall your stock ROM

  3. Status 7 error means you have modified your device, so you cannot apply the OTA update. However, you can flash the full ROM

  4. And one more thing…I don’t really know what hast happened to my phone(Micromax Canvas A1) but whenever I’m unlocking my phone it’s showing “could not start Home”…..Please help me hat should I do…Please reply asap!.

  5. I tried to update as per your instructions but it’s showing

  8. Can’t install June Security update on my android one.
    It fails every time I update it through OTA, once it restarts it shows I have the update pending. Cleared cache and when it didn’t work, I Did a factory reset but to no avail. I’m using spice dream uno. Last successful update: May 1 2016

  9. I understand that you have updated your phone to 5.1 from service center. Check for unlocked bootloader, if unlocked, relock it and try the OTA update. Alternatively, you can flash the full firmware via ADB.

  12. When you see ‘No Command’ hold Power button, then press and release Volume up button to enter into recovery mode.

  13. Kannan, i tried what you said, but after selected recovery mode, few seconds later it is showing “no command” in my micro max android one mobile. By mobile updation also it is showing err on boot time. Please tell me how to rectify this.

  14. For updating with official OTA, your device should be in stock (no custom recovery, root access and unlocked bootloader) and update to the latest version.

  15. You may try by deleting the cache partition by going to stock recovery. Also, enable battery saver mode and app standby.

  16. While selecting from memory card. During manual upgrading in recovery mode
    There is no OTA file shown.
    I downloaded it already

  17. For Karbonn Sparkle V, go here [] and download the update.
