FFB supports only one T-CHUCIPDEUC-3000.0 firmware. This is the preFEB and needed.
I don`t know why you`re trying to install postfebruary firmware. You already have the same firmware active!!!

So hash file does not match because it is not for this firmware version... Why don`t you read manual carefully?

Use this: T-CHUCIPDEUC-3000.0. and this MacPart.bin. Don`t forget to extract to right place.

p.s. Ok, i see, you have it already. See you? which firmware version is it for?

Use files from here and FFB. I see you haven`t understand what really you `re doing. Please, read steps you have to do more careful else you`ll brick TV which i think is out of warranty. So don`t risk. All steps what to do are explaned with pictures on my first post. You have just read and follow.

So i already said, you`re flashing your CI+ device with firmware from CI model.
Next time you flashed TV with firmware for your TV BUT you used different firmware and MacPart.bin files....

You haven`t downgraded firmware successfully. That`s why TV is showing you have T-CHUCIPDEUC-3001.1...

All what you need to do i wrote on this post.

p.s. Firmware T-CHUCIPDEUC-3001.1 is different than 3000.0.

No no wait. Give please me full logs. This error is not your foul.

p.s. Needed to do some bugfixes. CI+ behaves a bit other than CI.

Today i re-uploaded fixed version (0.6.0.1). Please remove SamygoHorse_fake (it removes FFB also), install new version and try again.
Or might you tried with this version already? Show log please

ATTENTION. Fresh info. Due some problems I removed support of B650/750 T-CHLCIPDEUC. New version (0.6.1) uploaded and available for downloading. If you have v 0.6.0.1, dont use on T-CHLCIPDEUC! Brick danger!
