Good morning,

I tried the second method twice but it doesn't work
I downloaded the file "black view-bv8000 pro_2018062921_s21v57c2k_jk_tee-ota.zip"
at the root of the SD card
I validated "Apply update from SD card"

then here are the messages:
--Install /sdcard/black view-bv8000 pro_2018062921_s21v57c2k_jk_tee-ota .zip ...
Opening update package
Verifying update package...
Update package verification took 21.8 s (result 1).
Installation aborted.

And back to the menu, here is what is indicated at the top of the page:
Android Recovery
Blackview/BV8000Pro/BV8000Pro
7.0/NRD90M/1520422331
user/release-keys
Use Volume up/down and power.

I also tried the first method several times and without success too.

Where is the bug
My BV8000 Pro is in the version :
Android Version
7.0 
Android security patch level
July 5, 2017
Kernel version
4.4.15
root@android #14
Thu Aug 3 15:09:38 CST 207
Build number
BV8000PRO-Blackview-V0.1_20170803

I used all methods, including going back to a previous version (20171227 also failed) from the SD card, from the smartphone root...etc...And IMPOSSIBLE to do this update. Of course, after each update I did a reset factory.

Here are 2 links to the log files following an update today August 13, 2018 with the file "black view-bv8000 pro_2018062921_s21v57c2k_jk_tee-ota.zip" with the update method via the phone settings

Can you tell me where the bug came from?

Thank you in advance.

Thank you in advance for your help.

instead of doing downgrade by sdcard, try to do it by flash tool. that worked with me.

The problem might be because of memory card. Try another memory card and format, then drop the zip file and install firmware

OK.

I followed your advice and after some difficulties of understanding and rereading the posts, I managed to come back in version 2017 12 27, then after the update to Oreo 8.0 it went well.

Thank you all for your help.
