My Android device YU Yuphoria is currently bricked and stuck in a bootloop. What I tried to do to cause this was that I first rooted the phone and installed TWRP. Then I installed Android Nougat on it, which was a success for the first few days but later got corrupted somehow. Now I'm stuck in a bootloop. Whenever I try to flash its stock ROM, it gives an error message "E: failed to mount". Infact, whatever I try to do in the Cynogen recovery mode, it gives this same error message. Can someone help me out of this?

  • So you need to flash it using a computer

You should try flashing the phone using a computer.

  • Download any firmware from this link. - all are for model Y5010a, since you didn't mention which model.

  • Unzip it and you'll find drivers, flash files and the flashing instructions.

  • Install drivers then follow the instructions for flashing.

Your​ phone should work fine now.


I thought it would help if I reproduce all flashing steps here

  • First download the Firmware, Flash tool and driver from above link

  • Extract the file (zip files) to desktop (You need to install winrar software or 7zip to Extract)

  • Open Driver folder and install Qualcomm_USB_Driver_Setup.exe file and wait until finish installation.

  • Open QPST.WIN.2.7_Installer-00430.1 folder, install setup.exe 

  • Now open QFIL from the "C:\Program Files\Qualcomm\QPST\bin" path.

  • Tick on Flat Build option

  • Go to Programmer Path and click on Browse.. button and choose prog_emmc_firehose_8916.mbn file

  • Click on Load XML... button and choose rawprogram_unsparse.xml file and then choose patch0.xml file from the Firmware folder

  • Now connect USB cable to the phone while holding​ volume up + volume down buttons.

  • Drivers should be installed. Just Click on Download button on the programm and wait until finish procedure.
