This model have same mainboard and have all files you need.
Make a original files backup and test it.

Hello.
I see three possible causes for your problem. One of the causes will be some type of incompatibility of the dump with the tool used to record the memory. Another cause may be that the tool configuration has some type of adjustment that is not compatible. Another option is that the EMMC chip is defective and this is the reason why the backup failed and it is now impossible to write all the software into memory.
I posted another emmc dump online from a TV with the same main board. If you want, download this backup and test if it works:

hi , i appreciate your trying to help , that what makes this fourm wounderful
i believe the emmc chip has some life still , helth report gives me :


Device Life Time Estimation (MLC) [269]: 0x04   30% - 40% device life time used
Device Life Time Estimation (SLC) [268]: 0x04   30% - 40% device life time used
Pre EOL information [267]: 0x01   Normal
i think userdata area has some bad blocks
the tv normaly comes on and freezw sometime or bootloop on logo
, the files you gave me now has  5 bin files , normaly any good backup files from easyjag box has at least one extcsd file, which is the config file
your file does not have it, may you please explain what do i need to do ? am i missing something here?

I don't use this programmer like yours, I don't know the settings. This backup was provided to me by a colleague, I didn't make it. You can test renaming the files, using the names of the original files that you copied from the TV. If the files have the same name you may be able to program the memory.
Unfortunately I don't have another dump of this main board.
