Reinstall fermwear

[NTG]

If I download fermwear from sammobile and install using Odin will the warranty get void.??

[nipoo]

I think yes. Why should you want to do something like that?

[BlackDemon223]

No.You will void your warrenty only If you flashed a custom recovery (ex- TWRP) , rooted, or tripped knox by somehow.

[Tharuchan]

No brother not void your warranty.
after flashing knox counter say 0×0
it mean not void your warranty

[NTG]

Thanks mine is M31. does not have knox

[Tharuchan]

oki, you haven't knox
but all devices have warranty void option in download mode

[NTG]

How can I check

[Tharuchan]

first power off your device, after 5 - 6 second press and hold power button and volume down button same time.after you can see blue or green WARNING screen, press the volume up button to confirm. you can see your device warranty status and this mode is your flashing mode (odin mode)

I did my firmware upgrade through odin by downloading the official os through Sammobile. There is word called KG stsues: checking but previously in download mode there were no such word. maybe it came with the upgrade. do you know anything about it bro?

[Tharuchan]

oh brother, i am sure your device is already warranty void. KG status or RMM status is new security in samsung bootloader. you flash twrp or any custom binary on your device?
