BV8000 pro not charging issue fixed
My BV8000 pro malfunctioned with skipping/stuttering audio then shut down
I Powered it back on and 2 hours later it happened again
I Powered it back on.. put it on charge and went to bed
In the morning phone would not power on or show any sign of life
Connecting the charger made the red led flicker faintly but did not reach the charging screen animation that I would expect to see
Purchased and installed a new charge board… but this seemed to have no effect on my issue.
Removed the battery and wired a 3.1a 5v charger directly to the terminals bypassing whatever the long thing circuit board is on top of the battery. I have a usb voltage meter that showed me that the battery was charging.
After putting 400mah into the battery it was getting hot and the display on the voltage meter burned out THIS WAS PROBABLY DANGEROUSE
After reinserting the battery the phone powered on but hung at the blackview/android splash screen
After a short time… extremely small blue squares could be seen around the blackview logo text.
I was able to reboot the phone into twrp recovery and I did all kinds of wipes and restores to no avail
But noticed that there was no battery level indicated in twrp recovery? so I figured that the long thin circuit on top of the battery could be the issue?
Purchased and installed a battey…
Now when I connect the charger I get the same red led flickering faintly
I do get the charge animation on the screen but it sits at 0%
And after a short time… extremely small blue squares could be seen around the battery icon. like with the splash screen
So I figure… maybe the malfunction has corrupted some kind of battery monitoring partition?
I tried to reflash the phone with rom 20180308_s21v57c2k_jk_fsm program SP_MDT_v3.1712
but It refused to work
I tried everything.. cables, drivers… etc.
Then I tried a reflash with rom 20180308_s21v57c2k_jk_fsm program SP_Flash_Tool_exe_Windows_v5.1744.00.000
The flash was successful
The phone booted and presented the android welcome screen
And the phone is now charging
So some or all of these steps seem to have fixed my issue.
I hope this helps some of you guys out

Dear blackview admin when you lock threads with..
“Be sure you use the original cable with long plug and it is inserted correct.
Flashing can work also with empty phone.
If nothing helps exchange the device over seller”
And
“Hi there,
it really looks like a bad hardware fault. Unfortunately your only solution is to contact your seller for a replacement.
The only thing you can try before sending it back is to charge your device using another cable + the micro-usb/USB-C adapter.
This will exclude a cable fault.”
It prevents us from helping each other and finding real solutions.
