Tried the usual? Try with a different HDMI cable, ports on the TV and even test with a different TV.
If still fails, try booting into the recovery mode.. It should have one, only a question of how to access it.. From within the recover mode, try wiping cache & dalvik to see if that forces it.. As a last resort, factory reset and or flash the firmware via USB method.

U mean q10 or q10pro?

Can u describe what requests for what updates?

Yes, i wanted to know if the update is for the box firmware or some app.

I do not think it is the box firmware as himedia is not known to do that. It is normally done manually via settings, online or via usb.

Still, if it was a firmware update that failed, it will not install, will fall back on last firmware once u power off n on again.

If app update.... i hv seen apps that hijack the launcher upon startup. If this app had an update and failed or upset the box firmware, u will get strange things. Once this app is removed, all will be good.

You definitely need to take the box back to seller to diagnose, fix.

Do you mean the below screen?

P/S: smileguy not purchase from me, but it is interesting to understand. Himedia ready the OTA for Q5 and Q10 Pro recently. I'm checking with Himedia to get more detail.

Have u try factory reset?
