Fully sertified version of the tv is m5502ua and costs 14000 uah (=520 usd).
Some sellers sell nor sertified tvs for around 10000 uah (=370 usd)
So i traded 150$ for a headache

Indeed that's why I didn't talk about SM yet.

LOL, means you didn't even have the right to make a channel search!?

I still don't believe in any modified fw.
Also if seller was "certified" he definitely wouldn't sell to Ukraine from Hungary.

You sure remote works?

I was more thinking of return cost to supposedly "restore fw"...

They sell tvs half illegally
Its ok in Ukraine

Pin is not reqired to search channels on this model

In the end they agreed to pay sipment costs, but i cant send them freaking tv every time frmwr gets fcked

Well, it looks you searched forum already and all infos we own are there. If key combinations are disabled in some way, I'm afraid you won't be able to do much by yourself, and have to remain "hostage"

Last thing i want to ask, if i flash firmware from the model m5502ua witch is sertified for Ukraine? Any chance it will help or mayby brick tv? Any chance that is exactly what seller does?
As well as i know ther is no hw differences

You can try to download firmwares from .hu or .ua, you'll just notice they're absolutely the same. So you'll be able to flash only if you don't have latest already (no downgrade possible), but updating usually don't change any setting anyway.
The trick is definitely not in firmware, I'd bet on some dumb flag file in user space, causing stupid restrictions...

They can flash modified SoC eeprom with some settings in it. They possible can even modify such eeprom for their needs. You reset fw, you clean eeprom to defaults = bingo, tv does not work in your region

So can i do anything myself?

Only assuming, but if juusso was right maybe EEPROM reset could help (note that TV would then ask to setup some SM values you can't reach/save now). Wouldn't help in case of flag file hypothesis though.
