• Select 'Reboot system now'. Alternatively you can perform a factory data reset here by choosing 'Wipe data/factory reset'
  

Kind request from users:
Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with SP Flash Tool in Firmware Upgrade mode. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

After FOTA update I get the watermark "The software version is incorrect, please download the correct software"

I flashed my A9 Pro 2020 with the Firmware Upgrade option in the SP Flash Tool and used the Vcom drivers in SP Flash tool folder (Driver).  Pressing and hold vol-up / vol-down together and connecting the cable worked for me!

Hi!
I found issue about ROM of Umidigi A9 Pro.
The randomization of MAC address for Wi-Fi return same address when it is connected same access point.


I have two Umidigi A9 Pro (2020 4GB model), and connected to my access point with option "Use randomized MAC(default)"

However, the devices seem to use same MAC address. I think this is not random.
After that, devices has disconnected from AP. I think it is because of exists of two same MAC address in a local network.
I turned off randomized MAC address to avoid this issue.

I notice this with UMIDIGI_A9_Pro_64GB_V1.0_20201121.
And I also tried it with V1.0_20210128.
The issue is also occurred on both ROM.

Is this issue known? and will it be fixed?

If here is not suit for issue report, please tell me where to report.

Hi Mr. bencebacsi
I posted a question and reported issue about ROM of Umidigi A9 pro last week.
Is it issue of ROM of it? And Is this known issue?

Personally, I don't feel the issue is critical. Because I can turn off random MAC address.
But as a company, it may be critical issue of OS and ROM.
I also tried with A7 Pro and the issue has also occured.
Do you know fundamental solution of the issue?

I wish this report will be helpful for Umidigi

Hi Mr. bencebacsi

How about this???

My A9 Pro 2020 got updated to UMIDIGI_A9_PRO_1_64GB_V1.0_20210316 rom when I bought, and I think this ROM is for A9 Pro 2021.Sometimes it restarts itself.
I'll install the last correct A9 Pro 2020 ROM: UMIDIGI_A9_PRO_64GB_V1-0_20210128
