  3. I thought that you have tried Android 7.1.2 Nougat based custom ROM. Your issue may be due to outdated bootloader, so update the bootloader and try custom ROM. Also, let us know the exact error messages you have got.

  57. It does not install and gives me an error stating :-
    /dev/block/bootdevice/by-name/system has been remounted…..something

  58. I don’t want to replacement of my mobile, i want rectifications only. and i heard about all YU Yureka phones are not good when compare to battery and network and other issues

  60. I have downloaded and it is showing signature failed and aborted when tried manually. I don’t know why the update not sent to me.

  80. It is not installing on my yureka plus 5.0.2 I tried to install it many times but it often says installation aborted saying this device has YU/yureka/yureka:5.0.2/LRX22G/yng1tas3eg:user/release-keys
