did you take note of the build number of your J8 before flashing?
the combination for recovery mode is vol up + power button not the other way round
also try vol down + power see if you can get into factory mode

What is a build number?
I have tried both combination ...they are not working
The best I get when I brings factory mode is rf calibration test fail

refer to https://www.hovatek.com/blog/your-phone-...verything/ for build no.
maybe the vol up key is faulty.

It may work, usually those kitkat/lollipop phones require factory reset after flashing firmware.

You can use NCK mtk to format user data pending when you fix your volume button
You can get it here https://www.hovatek.com/redirectcode.php...RkJMdUxNcw==

There are two modes here
1. Recovery (volume up + Power in that order) as explained @ https://www.hovatek.com/forum/thread-479.html
2. Factory mode (volume down + Power).

What we're interested in is recovery mode. Also, how many different J8 firmware @ https://www.hovatek.com/forum/thread-19362.html have you tried?
