So, when you connect the device to PC, You'll see something like this in the device manager,
------------------------------------------
Download Section
------------------------------------
Here is the full mmcblk0.img backup i've made and tested myself to unbrick alot of 816W,

Here is the tool we're going to use to write the img file into the SD card,
Win32DiskImager
----------------------------
Unbrick Guide
---------------------------
Summary of the process
-------------------------------------------------
We will write an backup of mmcblk0 from a working device (same as the dead one) to an SD Card (same size as the internal memory),
Then we put that SD into the phone and let it boot from the SD Card,
Then we flash the phone with it's Official Firmware,
That's it
Detailed Guide
------------------------------
1. Go to the Download section and download both (mmcblk0.img and win32diskimager),
2. Connect 8GB SD Card to PC via SD Card Reader,
3. Setup Win32DiskImager and Run it,
4. From Win32DiskImager do as this image,
5. Just let it finish, Then disconnect the SD Card,
6. Make sure the device's battery is well charged,
7. Put the SD Card into the phone,
8. Now try to boot into bootloader mode by pressing,
Vol- & Power button
9. After few seconds phone should boot into bootloader mode,
10. Now flash your phone according to your device info and case
(S-OFF, S-ON, SuperCID, BL Locked or Unlocked)
11. After flashing process finish, Your phone now is bootable working as it should be,
12. There is no 12, we're done ..
------------------------------------------------------
Final Word
---------------------
This method not only works with 816w, it should work for all Qualcomm devices, but you'll need the right mmcblk0.img backup.
I have tested this method myself with 3 phones, 2 of 'em are working fine now,
the third one powered on but it has a faulty EMMC so, it doesn't accept flashing, and here's one of the working,
----------------------------------------------------
I've been working on this for almost 3 days,
So, in case this guide was helpful for you,
Just hit "Thanks"
