Hi admin, is there an official way to rollback to Android 6 ? I was very happy with Android 6 and the BV6000 rugged phone. But after updating to Android 7, there are issues with WIFI and the battery runs out much more quickly. I find it annoying with THE Android 7 under testing.

Please follow the link to install.

I downloaded BV6000_Blackview_V01_201610251.zip and unzipped it to a folder. But I can't find FlashTools or Flash_tool.exe. Where is this tool ?

About flash_tool.exe, I searched http://www.needrom.com/download/sp-flas ... v5-1640-2/ and downloaded the version for Windows, which I'm using. Is it ok ?

follow this instruction but when i enter android 6, i always get notification "sim card removed" and both of my simcard is undetected.
man this phone is soo buggy... kinda regret buying this bv6000

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.

One question kkleung...
After you rolled back to 6.0 did you need to reinstall all of your previous apps and contacts etc...???

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.
