IPTV widget does tons of reads/writes. Widgets to watch films online.. (Cache read-write) ..They read and write a lot.
However, users install these widgets. The question about "tons of reads/writes" does not arise.

Someone's review - this is not a proof.
Because we can not exclude marriage TVs, failure of internal storage for reasons beyond the control of SamyGO.
Similarly, the internal storage can be damaged during installation of application from Samsung Apps.

Yeah and those tons of users reporting broken nands and wanting as to help them with "boot loop" have nothing to do with it
Anyway I don't care if user bricks his TV using some stupid widgets but I don't want my root to be the culprit

"tons of users"
. Do not invent. And enough fantasizing.

[Ended] SamyGO Extensions on F series - a huge number of downloads.
All of these methods work without USB, with image-file (128mb.xfs or samyext4.img) in memory of TV. But THERE IS NO EVIDENCE that someone had received a brick!
Guys, not use programs for IPTV, widgets for watching movies, etc.! Otherwise you will get a "brick" !
Sectroyer forbids to do it !

Well, without wanting to add fire to the discussion, mihd's root has an additional advantage apart from freeing up a USB port - and that is (believe it or not): security!
My use case is the following - I use root with libPinCode (I forgot the actual name but it locks the TV with PIN on demand) in order to impose a TV watching limit for the kids. This will be especially helpful when they will be older and home alone. Chances are that they'll figure out they can bypass it if they unplug the root USB and power-cycle the TV, but it might be more difficult for them to track down this thread and figure out what is the magic file that stops root at boot. So, better security for my use case
Regarding excessive usage of internal flash - although this root increases the read/writes to internal flash, I think that flash is EMMC (like the ones found in smartphones) and has better quality than most USB drives. It should support wear leveling automatically. It should be good for years of usage - most likely something else will fail thanks to Samsung's Planned Obsolescence program (TM).
@mihd: Can you also add an "unroot" guide to your first post - in case it's needed for whatever reason? Also, can one delete samyext4.img by resetting/formatting the Samsung HUB? Also, in case of samyext4.img corruption, what is the replacement/recovery procedure (can we get a minimal shell to run a fsck on it)?
Also, a suggestion - maybe you could implement a switch (a special file on USB) that triggers reading samyext4.img from USB instead of from internal storage. That way if anything bad happens with the internal image you can boot a rooted system and repair things manually?

This procedure is described. But it is not so pronounced.
Running of widget SamyGO-H(Uninstall) (appears after installation in SmartHub) used to remove SamyGO startup files.
Removing of widget SamyGO-H(Uninstall) in Smart Hub deletes samyext4.img .

Yes. Because Samsung HUB resetting removes widget SamyGO-H(Uninstall).

STOP_SAMYGO works. In this mode netcat on port 3023 or telnet on port 3123 can be used to correct errors.
Now I'm thinking ... FTP probably also need to be added.

Is it necessary?
FTP in STOP_SAMYGO mode - really necessary thing.

Check for file "STOP_SAMYGO_BUT_WITH_FTP"
Useless imho, FTP adds nothing you can't already do with netcat, and better keep "safe mode" as safe as possible, but it's up to you...

Copying samyext4.img from PC, copying samyext4.img to PC.. Is it possible these procedures in "safe mode" through netcat or telnet? As far as I know, no.
In addition, you can use WinSCP or Total Commander for FTP.

I understand you.
But it is much more convenient to do it with a computer, and not to go with the stick from the TV to the PC and vice versa.
