Help with Fengmi 4K Cinema UST projector


Hello everybody,

I'm new to the forum as a writer, even if I've been reading regularly. Sorry if I'm asking help on my very first post..

As in title, I really need help with my projector. It's a Fengmi 4K Cinema UST bought in January 2020. Model: L176FCN
I had an issue with a Firmware update and now the projector is dead and can't access the "Recovery" folder for backup.

I would need any other owner of a recent Fengmi 4K to share with me the content of their recovery backup folder.
It's not a difficult procedure and I can guide through it.

I would be really grateful to anybody willing to help me fixing it.

Thanks already!


Unfortunately I'm still stuck.
My hardware version is fm_10 and we are still trying to retrieve a "dev/block/backup" from somebody with the same hw version.

On the xda forum there a couple of different firmwares that you can try from other Fengmi 4K Cinema, you might be lucky and find the one that matches your hw.
