Hello.
Plz help me out. 
I've been trying to flash (write stock ROM) my Tecno L9 plus with miracle box 2.27A. 
The phone was being detected i.e "Connected to phone" . But always stopped at "Downloading Boot8" then would show "ERR21002.00" in red colour
The Phone is not powering on after I wrongly flashed a corrupted stock roms I copied from another phone of the same model. And been trying to use Miracle box to fix it. 
I've tried to used Windows 7, 8 and 10, with MTK DA and Preloader drivers installed. Always gave same error. 
Please, help out! 

Thank you.

Thank you.

have you tried disconnecting / reconnecting the battery then retry flashing?
you can also try flashing miracle box firmware using nck box @ https://www.hovatek.com/forum/thread-26431.html ; see if that works out for you

Thank you, X3non. 
The battery is inbuilt.
I will try out the NCK box you recommended. 
Thanks a lot, sir. 

And please, what is the meaning of the error "err21002.00" of Miracle box and what could have caused it?

you need to loosen the back to get to the battery
"err21002.00" only miracle box team can tell what the error means and the real cause. we can only speculate

I've removed the battery. It didn't detect the phone without battery. And when I reconnected the battery, still saying ERR21002.00

try other different miracle box versions, if both miracle box and nck box fail
then download only scatter file from factory firmware @ https://www.hovatek.com/forum/thread-19383.html
flash this scatter file along with the other firmware files from your firmware build using SP flash tool

[dpol]

As a matter of addition: Pressing and holding either of the Vol +/- or both, just before the phone is connected for download, helps in making the flashing or reading phones with inbuilt batteries doable, especially when using Miracle Box when all requirements have been ticked.

Thanks.
