Hi this is my 1st post so sorry if it been asked before. In have my P10 plus running b150 firmware.. I had unlocked the boot loader with adb and went to install a new firmware but decided against it. But now whenever I reboot or power off my phone when it reboots I get the msg saying the phone isn't secure and can't be trusted. I've tried the fastboot OEM relock plus code in adb but all I get is an error saying root is at risk.
Any advice appreciated.
BTW I don't want to flash an OEM firmware if possible.

Hello,
I want to relock the bootloader and go back to stock.
I tried flashing stock firmware using fastboot.
fastboot oem lock begin
flashed stock firmware
fastboot oem lock
But Bootloader is still unlocked.
I got message as first flash full stock system. Something like that. Don't remember as I tried this a week ago.
Any help will be highly appreciated.
Thank you in advance.
Edit : I also tried the Windows tool provided by one of the members but it failed too.
I used the same to unlock in the first place.
I think it depends on what you want to achive. While you might be able to re-lock the bootloader (which means it can't be flashed without being unlocked again), you will never ever get rid of the unlock message again. This - to my understanding - is an efuse which is permanently set. If you want to remove the unlocked bootloader boot message, I'd stay unlocked and would just flash a different boot logo (logo.bin) where the unlocked gfx are replaced with the standard gfx thus showing the standard boot logo.
I would like to relock the bootloader altogether.
I don't think you can. You can lock it but you can't remove the warning that it has been tampered with.
I don't care about the warning.
I just want to re-lock it.
Flashing the Official firmware for my Country - India did the job.
Last time I tried with firmware for ASIA.
I don't see any reason for that to fail but you never know.
Thanks for replying.
hey can you give me the link for that rom im also using the indian version but unable to lock the bootloader
I seem to have lost the ability to unlock the bootloader of my XT1700. I previously had unlocked the bootloader and installed TWRP and SuperSU, which took a while to figure out, but it worked. Today I tried to install a newer version of the stock firmware using SP flash tool (from here), which seemed to work fine, except now I find I am unable to reinstalled TWRP or SuperSU because I cannot unlock the boot loader.
When the phone boots, I still see the "device unlocked" message, and I have enabled oem unlocking and USB debugging in the developer options menu, however when I go into fastboot mode, if I run the "fastboot oem unlock" command, when the phone prompts me to press up or down, I get an "unlocking failed" error, and Fastboot reports "Unlock operation is not allowed"
Any ideas on how I can unlock this device again?
So it seems like those firmware images must have locked boot loaders. I ended up installing an xt1706 firmware instead (from here) and was able to unlock the boot loader successfully.
Anyone know where to get xt1700 stock firmwares with unlocked boot loader?
Trying to flash an OTA update bricks my phone, it just loops and boots into recovery mode, can't unlock the bootloader because it's not supported, I get in cmd "oem unlock is not allowed"
I will try the dm-veriry removal method tonight and see if it works
Can anyone tell me how to unbrick the phone, when I flash nougat (it fails which is normal) and oreo I get "error!" And my phones just a pointless paperweight until I can find an unbrick method
I can still boot into fastboot BTW
And also my bootloader is still on 7.1.2
I have a A2017U that I just downgraded to B35 using this guide: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413
I want to lock the bootloader to stop the annoying boot warning but can't get into fastboot when using AXON7TOOLKIT.
I tried flashing A2017U_FASTBOOT_UNLOCK_EDL (downloaded from https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128) through miFlash but I still can't get into the bootloader.
What can I do?
EDIT: Thanks everyone! I used the toolkit to unlock the bootloader again, then locked it. For some reason I couldn't access the bootloader even though i got the bootloader ulocked warning.

You only want to lock it because of the boot warning? There are flashables to get rid of that... I dom't know which exact files there are for stock B35 or Oreo but there are some going around.
hell you could even go custom and use the splash bootstack if you wanted.
If you want to lock anyways, you have to get an A2017U B19 package and flash it via EDL Tool (or MiFlash). Right after that you'll have fastboot. enable oem unlocking then enter fastboot and issue fastboot oem lock and you're done. But it's way too overkill if you want to just get rid of the 5 sec screen

you need to flash original stock rom for your device trough edl. (rom your device came from factory,marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
PS: you dont need locked bootloader to recieve ota's,and make sure you are on the firmware your device came shipped with!!
You need a locked bootloader to get rid of the warning message ( dont flash any mod package that claims it delete the warning page)
Hello all! I have been trying to unlock my bootloader on my SGP311. I have searched the threads, followed the instructions, and still have problems. i initially looked at my service menu to determine if it is unlockable and it said yes. I then went through the steps to unlock it and it kept saying failed. Then, it finally worked, and my tablet rebooted. i got dual recovery loaded and then proceeded to wipe and install lineageOS from recovery. recovery kept failing to install the new rom. i then had to reflash a stock rom because the tablet wouldnt even boot into recovery again. now my service menu simply says rooting status: unknown and says nothing about the bootloader. What the heck happened?

You can't install LOS Rom from the dual recovery (XZDR). By flashing stock ROM, you bootloader may be locked again.
Check this guide to unlock it, and install LOS.
It simply will not let me unlock the bootloader anymore. And I can't seem to find a firmware that I can flash to get me to the appropriate version
so far, part of the problem is flashtool in androxyde still using the command fastboot -i 0x0fce oem unlock 0xkey. windows 10 denies this command every time and should be fastboot oem unlock 0xkey. But even doing so manually through the cmd prompt, it still will not let me unlock the bootloader. does anyone have a ftf file that has an unlockable bootloader? seems mine locked up completely when i reflashed the rom

bootloader is in device, not in firmware, so no such firmware exist you ask for.
