Flint 2 mt6000 firmware upgrade issue

I’ve signed up to the preview release firmwares and was able to update firmware to 4.7.4 release 1.
Today I noticed an update to 4.7 release 6.

The router doesn’t upgrade/downgrade its firmware.

I’ve tried to update firmware with keeping settings.
I’ve tried to update firmware without settings.
I’ve reverted firmware then tried to upgrade.
I’ve tried holding in the reset button.
I’ve tried to downgrade firmware.

Is anyone having an issue like this, also?

How should I proceed?

Any advice would be greatly appreciated, thanks for your time.

Hello,

Downgrade the firmware version is successful, is it?

Did you try manually upgrading the firmware from dl.gl-inet.com?

If no luck, you can try upgrading the firmware on uboot mode.
