Iron Pro soft brick

swissking

Hi everybody,
few moths ago, i bought an Iron Pro. Everything goes fine, until few days ago.
For some reason the 3g, didn't work, and i decided to restart the phone. But once i turned it on, it doesn't turn on.
So after some try, i was direct to a menu, as specified on this topic: http://community.umidigi.com/thread-1321-1-1.html.
I've tried to flash via Flashtools, the phone was recognized (the VCOM driver was recognized), and the operation went perfect. But, once i've tried to turn the phone on, it'seems the i hadn't do anything.
Please anybody can help me?

Anyone can help me?
The flash process come to the end successfully but, the phone seems that is not connected.
SP doesn't show any type of error.
I don't know what do.

So, you mean you can successfully flash your phone (you get the green checkmark at the end) but after that you can't power on your phone or at least establish a working USB connection?

swissking

Yes, exactly! I get the green checkmark, but once that i try to turn it on it's the same story.

You should try to charge your phone with an other USB cable (if you haven't done it yet) but if that doesn't help, I'd disassemble that phone and would check the USB lines, the battery voltage and the working of the power button.

I'll try and let know. Thank you.

Guys i've checked the USB lines and where good. But i can't check the battery, cause i don't have any multimeter.
I want to explain the situation:
1) I clean all the old drivers thanks to USB Review and thought Windows;                                          
2) I install the MTK driver (from the forum);
3) I open SPFlashtools and click to download (using Download mode disabling preloader);
4) I connect the phone via usb;
5) The phone is detected and the process start;
6) The flash process goes good.
But once i try to turn on the phone, pushing for long the power button:
the umi logo appears but the phone won't start.
I think that is not the battery because, every time i can access to the "strange" menu pushing the power button + the volume up.
Isn't strange that is the cable that don't work properly? The phone was recognized every time i connect it to SP Flashtools.
I'm actually, on holidays, once i return at home i'll buy a new USB cable.      
Any opinion can clarify me, please?
There's anything else i can try?
Thanks.

Originally you said that your phone can't turn on, not that it turns on but can't boot up. In this case there's no problem with the battery or the USB cable. I suggest you to flash your phone again but choose the 'Firmware Upgrade' option. That formats the flash memory before flashing. In that case you will flash the preloader as well but that doesn't cause any problem if you use a factory ROM (what Angel_UMI linked here) created for your phone.
