[JALEBI] [UNBRICK] [STOCK] Flashing Stock Firmware on Yu Yunique YU4711

Wiped 'System' while flashing CM and now stuck on 'Cyanogen Fastboot Mode' screen?
What's even worse, is that, you didn't enable USB Debugging!
This guide is for you! Read On!

Yes, you guessed it right! You can get your soft-bricked Yunique up and alive, and I did this too, so I guess this is the only method that works.

Some things before we start:

1. This guide is tested to work on YUNIQUE ONLY, and not any other devices. Try any other devices at your own risk.
2. This guide shall work only if your phone starts up and shows that ugly Fastboot screen. If the device doesn't show any signs of starting, get it to the service center.
3. Don't lodge an FIR on me if this doesn't work for you. Maybe you're not following the steps correctly, or you just aren't lucky.

Requisites:

1. Stock Firmware Zip: HERE
2. Qualcomm Drivers: HERE
3. Windows PC
4. Original/Good Quality USB Cable (else writing speed will be very slow and could even be interrupted).
5. The phone (Fully Charged. Since you can't see the battery level, I suggest you to plug it in for 2-3 hours to ensure enough battery for the process)
6. Patience

Now comes the real part. I've divided the procedure into two parts to make it easy for you. First, go through the entire post, then proceed.

Part 1- BACKSTAGE WORKS:

1. The file you will download has no extension (null extension) so you need to add the zip extension (.zip) at the end of the filename by renaming it. Only then it will be extractable. So go ahead and extract it.
2. Run the 'setup' from inside the 'Driver' folder inside the folder that you just extracted. Let it instal the drivers, then Restart your computer. Restarting is necessary.
3. Extract the 'QualcommDrv.zip' (Qualcomm Drivers Zip). Depending on your architecture, instal the driver by running either 'dpinst32.exe' or 'dpinst64.exe' which can be found inside 'Allx86' and 'Allx64' folders respectively.
4. Get your phone into that Fastboot screen by holding down Volume Up + Power button for 7-10 seconds.

Part 2- DAMN YOU, BRICK:

1. Run 'ets.startrun.exe' fron inside the 'HQXA CustomerDL EMMC V1.15 150706' folder.
2. While in fastboot mode, connect the phone to your computer.
3. Now in the ETS Flasher window, click on the USB Button (Butterfly Icon). This should open up a list of all interface ports and devices connected to them. Look under the 'DevDesc' field for your phone. It should be mentioned as 'Android Bootloader Interface' or 'Android Composite Hardware' or 'QCOM Interface'. Take a note of the port number in the format 'USB_XYZ' (like USB_202) because you shall need the port number. To find your device easily, remove all other USB devices till you're done unbricking.
4. Close the USB Device Manager window and get back to the ETS Flasher window. Hit the 'Set' button (beside the Butterfly Icon). Set 'Download Mode' to 'EmergencyDownload'. Now click on 'Change Path' and select the 'Firmware' folder found inside the extracted ROM Zip.
5. Under 'Port Settings', Select the port number you took a note of in the previous step, and make sure every other 'Thrd' box is set to NULL. Click 'Ok' to get back to the main window. Let it load the directory completely.
6. After the directory is loaded, push your phone into 'Download Mode' by pressing and holding all three physical buttons- VOLUME UP + POWER + VOLUME DOWN together for some time. The phone shall reboot into 'Cyanogen Download Mode'.
7. Once the 'Download Mode' screen appears, Press VOLUME UP to confirm. The screen shall now go blank and your computer should detect the device.
8. If your phone is detected by ETS Flasher, your phone should appear across the selected port. The 'Item' name should read 'sahara download mode' and 'P/F' should change to 'READY' from 'NO PHONE'. If you can't see these, it means your drivers are not properly installed. See the troubleshooting at the end of this post.
9. Now hit 'Start All' button and wait till the progress bar goes from zero all the way upto 100%. In my case, it took 7 minutes and 15 seconds to flash the phone, but it may vary.
10. After it has flashed your phone completely, your phone should restart automatically. Done! Mission Accomplished!

Troubleshooting:

• Phone doesn't reboot into Download Mode: Try a normal force rebbot first, by holding the power button for some seconds. After you feel a slight vibration, try to get into Download Mode and it should work.
• Phone is not detected in ETS Flash window: Follow these steps.
• Flashing stops in between, doesn't complete: The USB Port of your computer might have loose plates. Try changing to a different port and retry.

This is my first post here so I tried to be as descriptive as I can. If hit helped, don't forget to give :good: a thumbs up!
Cheers!
