Opps.
You needed to careful when you are using rm command.

I don't understand your TV situation too. What is the problem you have?
And also you need indicate your FULL MODEL. Like LExxB650T2W...
There is multiple models of B650, LA,LE,LN, CI, CI+... right?
And do you have ExLink cable? What TV returns as error messages?
So you can identify the real problem.
Wish you recover your TV soon.
This why, you needed to take BACKUP before playing your TV.

I think your TV reboots after 1 minute right?
This is sound of authld.
Since you changed your Game directory, authld checks some files under that directory. Even if it finds files, those files from changed version (do you have files for CI TV?) and does not same the original files (I believe), so TV restarts it self after. You can recover your TV (that I believe) but don't exactly know how you could. Might be you can copy some files from USB to TV's internal memory that re create hashes from this directory too.

Building an exlink cable is really easy, it also sold from any electronic shop or some one who can make solder could prepare one easily. I don't exactly know if that cable help you but I believe you will have more information about error with cable.

This authld problem also occurs if you changed mtd_exe and/or mtd_appdata partitions via force write. We are still looking and investigating to authld. You can find more information at this thread: http://forum.samygo.tv/viewtopic.php?f=2&t=655

Another way is booting with external USB with manually configured linux kernel, that doesn't start authld so you will have no restart and could cure your TV without time constraints. But this requires flash u-boot code to your TV.

flash u-boot code is not enough, still bootloader does not load u-boot. it need replaced from CI version of tv.

Calling samsung tech is another option. I guess its the fastest. Since you bricked your TV, It's out of warranty.
But Samsung placed booby trap into TV (authld) so that is Samsungs fault to produce TV with traps. Without authld, your TV will be working.
So I count that TV under warranty, but I guess samsung does not. If they understand what happened, will require money from you for repair.
Might be they will change of the motherboard. But you know the problem is about on the "software" there is no Hardware problem.
So proper Samsung tech needed to load new firmware only and doesn't want motherboard price from you just firmware installing and service price...
Don't know legal thing in your country but this is the truth.
