Yes, after rollback, need to re-install all the apps, contacts, bookmark, etc. Also, my phone failed to recognize my sim card, i.e. failed to make call. I performed "factory data reset" once and then it recovered. Now, my phone works fine with Android 6.0.

I prefer BV7000 pro. Before I buy it, I need to know how to attach security strap (安全卦繩) since I'll use it in watersports. I don't use NFC.

I experienced similar continuous-rebooting (with Android 7.0 only) when I'm in Hong Kong Science Park with WIFI turned on. In other places, this problem doesn't happen. I suspect there is some kind of WIFI protocol not handled by the phone WIFI driver.

Congratulations !!

Hi, I'm also wondering how to attach security strap to BV7000. I'm using BV6000, which has a bar at the bottom of the phone for us to attach the strap or string. Admin, could you show how to attach it for BV7000?

Thanks admin. I successfully rolled back to Android 6. The problem of continuous self-rebooting in Hong Kong Science Park with WIFI on disappeared. Battery consumption is normal. Everything is back to normal now.

Thanks Phil. I tried "Factory data reset" and the sim card appears again !!

I finally can flash the ROM of http://www.needrom.com/download/blackview-bv6000-4/ without error. In doing this, I have to install Mediatek USB VCOM Driver as well as the latest FlashTool. Also, the sequence of "pressing DOWNLOAD" then "Connect USB cable" is essential. If this is...

I tried flash_tool.exe (SP_Flash_Tool_exe_Windows_v5.1648.00.000) on Windows 7 PC. Loaded the file MT6755_Android_scatter.txt. Then connect the BV6000 to a USB port of PC. Then press Download. There is no progress. Nothing changed to my phone.

Installed update 20170223, same WIFI problem as before, i.e. continuous self-rebooting in Hong Kong Science Park when WIFI is ON.
