Recently I found a way to unbrick the phone by following this clip: https://www.youtube.com/watch?v=A3TmXtOA0IA

What I did:
- I Opened the SP Flash tool. Chose only the PRELOADER and hit "Download" (as describe in that clip at 16:38)
- Then I connected the Phone (with Battery inserted), pressed "Volume +" and "Power" Button at the same time. The phone was recognized in just 1 second, but it seems to be enough for download the PRELOADER to the phone. And the download process was success.
- After that, the phone became detected by my PC every time I connect. I could connect it to my PC and flash a full ROM to my BV5000, unplug it and connect to adapter and wall electric socket to charge it. The ROM I used is: https://mega.nz/#!j5tCERTA!ionIz-oaa3t2 ... ANe82kdxWc
- After charging for a while I turned it on. The phone took around 5 minutes to turn on, but it finally alive, and working normally. The Android 6.0 is a bit slower and lacks some functions I used in Android 5.1, but anyway I can use it again.

I like this phone's water proof body, large battery and low price. But I will use it only as a backup phone. I have to buy a new phone while this BV5000 had problem, and don't plan to buy any other phone from Blackview.

The phone it self is great for its price, but Blackview customer service turn their customers down.

Someone saw my clip on YouTube (https://youtu.be/RIE-L33oR9w) and suggested a similar solution. I hope other bricked phone users can find some useful information based on my experience.

I very problem with 6pcs BV5000 with last firmware version. This week all 6pcs phones power off and no available power on. For fix only wipe data or flash via Flashtools. Why is the same problem for all phones in one day ?

Thanks for you reply

Thank you for this information, I am struggling with the same problem myself but this gave me hope. I'll give a reply if it works!

But you have no idea how glad I am of this info. Thank you!!

I just wanted to say thank you. You are my savior!!!!!!!!!!!
I want to hug you right now DDDDDDDD

It works!!!

Get a different firmware... I used this one t89j-jk-bv5000-hd-33pgu-128g16g-1851_BV5000_C1_Blackview_V1.2_20160608_release. Then load and queue it in the SP tool for download... then hold power and volume up until the tool finds the phone and it will start the flash as the phone briefly connects... I just had _exactly_ the same problem, and recovered the phone to 5.1 this way
