Yes I flashed CSC not the HOME_CSC.
I download the firmware from updato.com, is it OFFICIAL? Anyway I can do firmware upgrade.

No idea, shouldn't affect anything though, just means the bootloader is unlocked, as long as you don't flash anything custom OTAs will work etc

questions about "TAMPERED" and S-OFF

My M8 is bootloader unlocked and S-OFF
Now i want to remove the "TAMPERED" flag in bootloader. How to do that?
Is it possible to "lock" the bootloader again? If the phone is "locked" but still S-OFF, is it possible to flash rom, recovery, firmware etc. ?
What if i want to get S-ON again? How to do that?
i succesfully removed the "TAMPERED" flag.
But what about locking the bootloader?

Is it still possible to flash rom, recovery, firmware etc. with a "locked" bootloader? Can i get back to s-on with a locked bootloader?

1. No, you need to be unlocked to use a custom recovery
2. Yes, but you don't ever have to go back to S-ON anyway

Yes, as if it's locked you can't flash a custom recovery (well, there is a way but it's a ball ache to do)

How to do that without unlocking BL?

Not that I'm aware of, you might want to try a Factory Data Reset first. After doing the appropriate backups first of course.
If that fails, unlock the BL, flash stock. Once you verify it works lock the BL again. You might have to FDR again to get the Play Store to show Certified if clearing data under Apps doesn't work.
I wish I could still trust my Robin, but I have a battery heating issue that nothing seems to fix. Hence my signature showing my former backup phone as my DD.

JSYK Your phone will not get sim/network locked if your phone is already sim/network unlocked.
(if by locked your referring to the sim/network lock)

[solved]Green Writing on Boot & OTA not working after CSC Change. (GWA2)

Hi all,
After flashing my GWA2 (SM-R830) following this guide to change my CSC, there's now Green Writing on my Watch whenever I boot the watch. In addition to that, OTA Updates are now failing.
A person in that post has the same issue as I had and fixed it by flashing stock firmware but that doesn't seem to fix it. I'm back to BTA1 and the green writing still persists as well as OTA still failing. The watch is fully working, except for OTA and said writing.
Anyone got a lead on why that is and possibly how to resolve it?
Edit: Solved it by reflashing it and leaving "Auto Reboot" ticked.

Is that reversible? or am I just stuck with non-working OTA?

Yes it's reversible. Flash this firmware using NetOdin https://drive.google.com/open?id=1ZaoBm2hFXT2QTeZxrS8j4sqqgVyp6Iqo . After that, use Galaxy Wearable to update Tizen to the latest version.
I have exactly the same problem with an Active 2. Can someone point me in a direction toward Firmware to re-flash an 820 too please? (is this just leftover from the combination firmware I used during a region change?)

I simply reflashed the 3-multi files and kept the "Auto Reboot" in netodin ticked.

Did you hold volume up to unlock the bootloader? Look at this picture. Note that it will format your device.

I don't know then, try disabling OEM unlock, rebooting, enabling OEM unlock again and rebooting again.
I already tried several times

Can you enter download mode? If you can, try to install the latest stock firmware. Install it with ODIN.
I already tried but I don't know if it has to be one firmware from different specific countries
