Umidigi A7 Pro - Android Q&A, Help & Troubleshooting

Hello. I purchased an A7 Pro, as soon as it arrived it was not doing the updates automatically, so I chose to update with the Flash Tool. I installed this latest version and it was a success.
However, while I was using the device, it crashed, turned off by itself and did not turn on again. I tried to do the process of installing the rom again, but it does not install the preloader because it does not recognize the USB connection as "Mediatek Preloader USB VCOM", in addition to constantly connecting and disconnecting.
Can you help me?

Hi Kzwir,
Since you were able to take a screen capture on your computer of the SP flash tool, I'm assuming that you have figured out how to use the Flash tool. Did you follow the directions on the Umidigi site: https://community.umidigi.com/forum.php?mod=viewthread&tid=16931 ?
On the A7 Pro can you boot into bootloader mode? (From Power Off, press power button and volume up button once in the selection screen press the volume up button until you highlight fastboot and then press the volume down button)
If you can get into fastboot/bootloader mode, I would (in an account with administrator privileges) 1. Try a different usb cable, 2. completely uninstall any drivers, reboot the computer and then plug the phone in again while in Fastboot mode and see if it recognizes the connection. 3. Try a different computer - (if you used this computer to flash the phone originally, I suspect that this isn't the issue).
Good luck!

Hi.
I used all the procedures indicated in the official forum, I managed to make the device recognized with the necessary port for formatting (Mediatek Preloader USB VCOM).
The only problem that persists and probably hinders my goal is the intermittent connection and disconnection of the device, not allowing Flash Tool to perform the installation.
In all cases, what happens in the image I posted occurs. It loads the red bar and then does not perform any other procedure.

With an intermittent connection, I would look at 1. a different cable and 1. a different USB port (like the ports on the motherboard vs the front ports on a desktop).
Good Luck!
