I tried unlocking bootloader but nothing happened. I tried this 3-4 times and suddenly my Phone gone blank.
Now the condition is neither LED or any kind of vibration is working. Phone is detected as Qualcomm Qloader 9008. I tried figuring out and found that bootloader is corrupt. Many person having Snapdragon Chipset have same problem. I found EMMC DL Tool which can repair this but in version 5.2.0.r I am getting invalid user error.
Then I tried Tool studio EMMC tool from ZTE but I am getting error while downloading the Hex file. Phone is detected but unfortunately I am not able to fix it.
Please go through screenshot.
Someone please help me to fix. Either using this emmc tool or anyother.
P.S. Went to SC they said to replace MB which will cost around 6500-7500. But I don't think to spend such money for repairing when I can but much better phone in that price segment.
