[Q] safe to reenable bootloader lock after flashing kernel - Galaxy S6 Q&A, Help & Troubleshooting

Hi,
Before I do anything stupid, i just upgraded S6 (920T) to 5.1.1 stock. I flashed unikernel afterwards and through root I froze all the bloat.
Now my question, am I able to lock the bootloader again?
Thanks

Rooted P907A...now what?

Hey guys, I recently rooted my P907A recently, and I am wondering is there any stuff I can do this boss of a tablet(aside from tweaks, SuperSU, KNOX disabling, and what not).
I've looked around for custom ROMs viable for me but this being a carrier based tablet(on stock 4.4.2(it was 5.1.1. before I reflashed with ODIN since towelroot would not work on 5.1.1 of THAT build.)) what will happen if this updated to 5.1.1. that build P907AUCU1BOH3 with root? Would it lose root and enable KNOX? Should I install a new custom ROM? Suggestions?
Right now it's 4.4.2 stock with SuperSu with root and stock bootloader.

flash without pc

Is it possible to flash bootloader, modem and twrp without a PC? My S6 doesn't communicate with any pc anymore. I did everything but it doesn't helped. So is there a way to do this?
If you are rooted yes. You can flash Twrp and modem through recovery, I'm not sure about the bootloader.
But if you are not rooted there is no way.
I am rooted. But is there a way to update to mm without bootloader? I don't think so. Looks like I am stuck with 5.1.1

Lost dev bootloader updating to PD1, any hope?

Hey everyone, in an attempt to update my baseband, I ended up losing developer bootloader status, and I'm now on stock PD1. Is there any hope for me to be able to regain root/unlocked bootloader? I tried flashing PB1, and it would flash alright, but got stuck on the Verizon logo animation.
I'm willing to try just about anything to get cyanogenmod back!

I would suggest that you first need to wipe your cache and dalvik, data as well if you want best results; then flash back to stock PB1. Re-root PB1, re unlock the bootloader of PB1, and then follow the instructions here regarding upgrading to PD1 with an unlocked bootloader (it is found on the OP of the thread that tells you how to unlock your bootloader. You should end up with the rooted version of whatever rom you are after while still having an unlocked PD1 bootloader.
Perfect, thanks! I believe I tried that but it's possible I didn't do it right, so I'll try again.

Question about XtreStoLite (G920F)

Please forgive if i'm posting incorrectly, have been a lurker for a while
I have a Samsung s6 G920F variant, locked onto o2 (UK network) I believe the bootloader is locked also.
I was on Lollipop (with pingpong root) and recently upgraded to Marshmallow 6.1, so my root is obviously gone, and it doesn't seem that there's root right now that works.
I really want to try out the XtreStoLite rom, theoretically could i flash this rom via odin, since its TW based, would it load on without root, and with locked bootloader? I don't really care about Xnox tripping, but I definitely don't want to brick the phone... I'm not sure if the XtreStoLite rom would count as 'stock based' therefore being recognized by the phone as an official operating system? If that sounds correct.

Link to root your phone correctly.
And Yes you can flash xtrastolite with a custom recovery and without root .
Agreed. ROM has root already. Since you're already on MM, don't flash BL and modem, just ROM & optionally addon. Note that if you replace the stock kernel, you'll probably lose root.

If you lose it, just flash the zip below again

Relocking Bootloader WITHOUT flashing

So I have stock 5.1 on my XT1033, rooted and bootloader unlocked. I wish to un-root and relock the bootloader (for security reasons?) but without having to go through the trouble of flashing the stock firmware since I already am on stock.
Do I really need to flash the stock firmware in order to re-lock? If not, then how do I re-lock?
TIA.
the relocking of bootloader will change nothing. flash Nought Roms & try Magisk Root Manager to hide root in important applications like banking.
and go for nought rom which is way better than 5.1.
