I've rooted my S4, and I'm running 5.0.1 Stock rooted firmware.
I'd like to re-lock the bootloader so that no one can hack my phone by flashing a zip with a lock screen bypass, if I lose it.
Is there anything that can re-lock the bootloader, while maintaining root?
Thanks.

I'm getting this phone soon, never had a Samsung before. When rooting this, is there a bootloader to unlock? And does Odin unlock it during the root process?
Thanks
If you want an unlocked bootloader, you have to purchase the Developer Edition.
The retail edition has a locked bootloader. You need to use safestrap if you want to flash roms, you will not be able to flash custom kernels. Odin is used to restore your phone, not unlock it.
The phone's bootloader is probably locked. It has never been unlocked, and I believe model SM-G900M was sold with the bootloader locked. (I tried to check if the bootloader is indeed locked, but fastboot did not detect the phone.)
I understand that in this scenario there is currently no way to root an S5, right?
It appears that the only way to go is to perform an Android downgrade. I would have to use Odin to flash a stock 4.4 ROM (is this correct?), then I would be able to root the phone with towelroot, unlock the bootloader and install flashfire on my device. Does this sound like a doable approach?
Suggestions/advice very much appreciated.
Thanks!
I'm on G900VVRU2BPB1 and I believe my bootloader is locked as I did root my phone and the samsung unlock app did not unlock my bootloader. I am rooted and I am wondering, there a way for me to go to MM and keep root? Or am I stuck at LP? If I read the information correctly, I am stuck at LP if I want to keep root correct?
If you're CID 11 the bootloader cannot be unlocked. Also there is no root method as of now for marshmallow. You must flash back to PB1 (lollipop) and root and unlock if possible.
Right now I have two CID 15 G900Vs with PB1 rooted 5.0 firmware and OD5 bootloader. I'd like to use the spare to try out MM 6.0.1 rooted using the unlock procedure.
I know that loading a post-OD5 stock bootloader is irreversible. If I use the procedure here:
https://forum.xda-developers.com/ve...t/rd-unlocking-galaxys-s5-bootloader-t3337909
to install an unlocked bootloader, is that an irreversible change? Will I be unable to go back to an earlier (OD5) bootloader or firmware after the unlock procedure?
If I use this procedure:
https://forum.xda-developers.com/verizon-galaxy-s5/general/update-qi2-t3688046
and install
Developer Bootloader Friendly/No Aboot No-Wipe Firmware:
G900VVRU2DQI2_G900VVZW2DQI2_G900VVRU2DQI2_HOME_No_ Aboot.tar.md5.zip
will I trip a KNOX flag or set any fuses or otherwise do anything that cannot be undone? I'd love to play with this stuff but want to make sure I can back it out if necessary.
Thanks,

I want to relock bootloader without downgrading to (or using) fw340. I intend to flash stock recovery then lock bootloader. After that flash stock pie rom vai stock recovery. does any method exists just to lock bootloader instead of flashing whole rom.
