  3. Nirman parkar Reply

    How long does it take to boot for the first time. I waited for almost 20mins and the phone was stuck on boot logo. Any help

  4. Nandan Hegde Reply

    hey, i did all the same as mentioned. Now my phone is continuously vibrating once switched on.

    • Nandan Hegde Reply

      Once after flashing, i locked the bootloader i guess that caused me that problem. Once i again i performed the same process without locking the boot loader, now its stuck in boot logo.

      • Nandan Hegde Reply

        Ok finally for the third time. It was a success. Scared me like hell

        • I’m glad you successfully managed to install it on your device..Can you share with others what you missed in first that other will take benefits with any issue.

    • dear, please help me, i am facing same problem and now very scare, because this phone belongs to my big brother, please suggest me what should i do now,,,,,, fast

  5. Nandan Hegde Reply

    Ya sure. After flashing with all the commands, i believe ” fastboot -i 0x1ebf oem lock ” this command of locking boot loader is causing the issue. Better not perform it and directly move onto rebooting once all the process is done. Please be patient as in for a while it looks like its stuck in boot loop. Later on it will boot normally. Also make sure you have charged your device well before performing to avoid unexpected power off during this process.

  6. Nandan Hegde Reply

    Also, I am aware its beta build and i have observed several bugs. How and where can i report it. Can you drop of a link to it which will be quite helpful for a small contribution.

  7. Nandan Hegde Reply

    Can this be rooted and can i install Custom recovery on this. I want to flash other ROM so am not sure how do i do it when i am having this beta build.

      • my yureka was rooted, and then i installed this os by following these methods, and later i realised my rood access have been denied after that full format, so if you flash this os, you will be unrooting your phone too along with it

  8. in cmd promt it says -i is not recognized as internal or external cmd how to find my device code

  9. hey if the phone is vibrating continuesly then how to put it back to fast boot mode i tried restating it is same even after restarting

  16. bhai koi to help kar do yaar. yureka phone update kiya, sare step follow kiye, ab phone vibrate ho raha h, pichle aadhe ghante se, please help me……..

    • Try again and this time skip step no 8. Some users says that cause the issue. Also try clearing the cache from recovery.

    • You don’t need device code for yunique.
      Try the code without device code like fastboot oem unlock.

  20. I have Custome rom(HexagonOS 6.0) installed in my Yureka YU5510. I want stock OS with 6.0 only and please confirm that can i flash this rom with Gapps.
    You r doing great job. Thanks in advance.

  21. I have installed this yu os on my yureka, and then i realized that i cannot switch to bootloader or fast boot mode , if i have to change to custom rom and root yureka, how can i do it?

  22. Did anyone figure out to install gapps along with this. Yuphoria.

  23. For those who face the problem for Opengapps … here is the solution.. Download YUOS Official – Andriod 6.0.1 from and use it… do all the steps just skip “”fastboot -i 0x1ebf oem lock”” reboot and enjoy ,,,,,,,,,,,,,

  24. Hi Sumit forgot to tag you, can you please advise me which procedure to follow for the official Marshmallow for Yu Yunique

    • Both the method works…the link you shared has batch files which automated the process and with above method you have to flash the files manually. Both methods will you can use any of them.

  25. Thanks for reply,

    In the disclaimer of, there is a Note that says YuOS MM does not support voice call feature for voLTE, is that true?

    Then I should stay on 5.1 until another build comes with the update, though the available MM build seems stable.

    • Hi Sumit, I have YU yurekha 5510 with upgraded 5.1 android lollipop, I have took a Jio sim the network bars has appeared but still my data services are not activated.does nt show any sign of lte or volte. Need help

    Can anyone tell me the advantages and disadvantages of installing this OS ???

  30. Hi! I followed these steps and stuck at the logo overnight. I tried to get it boot into fastboot mode (Vol Up+Power) and the phone is not detected, so I can try to reinstall.

  31. If this is official OS, why are we not getting it in software updates? Did anyone successfully upgraded to marshmallow using above steps, or any other url is there for Yu Yureka which has easy steps and no issues?
