It's easy to fix

Just follow my steps. :fingers-crossed:
1.Prepare the rom which was running ok before,for example, for me it was @satanduck 's prerooted TWRP S124 rom.
2.Open the SP flash tool.
3.Load the scatter file from the rom which worked ok for you.
4.Tick the box that says 'DA DL All With Check Sum'
5.Hit Firmware Upgrade
Now is the hardest step

1.Open the cover of your phone.
2.Look for the red reset button which was close to SD card and press it a few times.
3.Connect USB cable to your phone and firmware upgrade should start and wait for the green circle! :good::laugh:

Best luck :good:

What have you done to your phone? Did you install or flash something? Did you change something in system ?

Sent from my Lenovo P780 with TWRP 2.7.1.1

Yes, I installed mtk usb drivers. but I´m not sure if it´s ok o no. Because I have to connect the battery and push volume+up button to make it connected. and it´ll disappear immediately in device management window.

Hi,

Please verify that you have a correct production date. I got a P780 after 0314. please try the solution on this post

If this resolves your problem, that keep that preloader. With that you can almost flash every rom that there is with the flashtool.

(i'm very satisfied with the latest rom on needrom Vibeui2.0 (the rom page also offers the new preloader )

Greetz,

btw to try to flash with the new preloader set up the flashtool, push the red button on the back of your phone, connect the phone an release the button. If all the drivers are correct your phone will be flashed. ( this new batch phones gave me a heart attack also

, mine wasn't even 12 hours active before i softbricked it )

When I push the red button, phone can not be recognized by computer. Only I press the volume-up button, it can be recognized by computer.
I start the flash, then push volume-up button to make it connected, but then got BROM error. I attach the screen picture.

You must have this FlashTool - SP_Flash_Tool_v3.1304.0.119. Not Optional.
Check if your phone is produced in 2014. If it is you must use another preloader.

I think you should go to a service store. Thats my opinion.

I thought you have warranty on your phone !

So... this error appear when you try to flash wrong ROM or you have wrong drivers installed. Try to remove drivers you have installed and try to reinstall another driver.
Orrrr.. your phone could be a clone. Just an ideea ...
Could you tell us more about your phone... maybe pictures taken from battery or box who came with ?
