Thank you very much!!
So, I ill share my experience with rooting.
TV:
UE48H6270
My FW version was
2113.4. Anyway, on the start of this topic is list of models and their FW version and I found exactly same model, but with higher FW (2130.0). So, I risked everything(!) and updated to this version. And yes,
it can bee rooted without any problem! After update, I disabled OTN support (it was automatically enabled after update) and also I disabled auto update in Settings. Then, I adjusted settings again, because I entered Service menu before, which leads to reset of Settings.
Then, I ran scripts and followed guide - no problem. But then, I cannot telnet to TV. After some time, I check IP address to TV and found, that it is different from address, which I assigned manually in my router. If set Automatic DHCP in TV, it always take another address, but not that one manually entered (and yes, I also enter TV's MAC address). So, I entered all IP data in TV manually, and after that, I can telnet to TV.
After that, I only edited
(thanks to
zoelechat) and voila - I have everything, I wanted!!
One more hint - I cannot have only one USB flash in port, because it was set for recording and it is formatted by another filesystem, than FAT or VFAT. So, finally, I have one USB only formatted for recording in USB1 (labelled as for Camera) and second one, with root data is in USB2. I only deleted folder "
InstallSamyGO-H", because it in only widget for initial root. I leaved on this FAT32 USB flash only "
SamyGO" folder. With this configuration, everything goes well and smooth. And I have 3rd USB free (labelled as for HDD with rating 1A), so I can also use external HDD without limitation.
Hope, that my experience will help to somebody.
For mods: if you want to store FW 2130.0, which was worked for me perfectly, just let me know, where to upload (filesize is 887MB).
