The phone is vibrating when I press the power button. 
Like rebooting the preloader.
When I try flashing with special flash tool. 
The huawei connects and disconnects every 2 seconds. 
After the red bar loads. 
I have tried following up this two threads but still didn't work.

I noticed that when I hold down the power button before inserting the USB CABLE it stays for about 6-8 seconds long but doesn't still enter DA mode before disconnecting. 
It's urgent please.

When it disconnects, do you get any error on the tool you're using?
State the tool version and error you get.

flashed a new system.img through fastboot mode. Since it was disconnecting via flashtool. But before then it was stuck at boot animation. On its own, I didn't cause this.

Try the fixes for error 2004 @ https://www.hovatek.com/forum/thread-439.html
Have you tried flashing more partitions via fastboot?

If you apply the fixes and still get error, I think you should check the phone for hardware faults.

still the same thing. I have serviced the board.
What do you think I can do to the board.

[EMMANUS]

You should take it to a hardware technician.
