[Q]Re-Unlock bootloader after relocked

Had anyone tried it before?
After I unlock my bootloader using the official method, it is a silly way to unlock your Arc S bootloader. You will lost your DRM key and FOTA bricked, I learned my lesson. If you want to unlock your phone Testpointer method is obviously a better way.
So I relock my bootloader again using a common method you can find online:
http://forum.xda-developers.com/show...php?p=20422618
fastboot flash -i 0x0fce getvar version
fastboot flash -i 0x0fce oem unlock 0xKEY
Error: cannot load '0x0fce' is what I got after execute these command.
I am so desperate to get my bootloader unlock again and manage to switch between locked and unlock state.
Is there something to do with preset.ta file so I can unlock my device again. If the re-lock patch involving this file.
Well! It seem to solved.
Using following command:
fastboot getvar version
fastboot oem unlock 0xKEY
Thanks you guys!

Booting into Recovery Automatically!

I unlocked my bootloader. Installed TWRP and when I was on stock I updated my moto z play to 7.1.1. I know never update through OTA when custom recovery is installed. But I didn't know that earlier. Device got rebooted and directly booted into TWRP and nothing happened. I then rebooted to bootloader and started the device and it booted up!
The problem is each time the phone is rebooted it goes into recovery and i have to reboot it to bootloader to start!
How can I solve this?
I'm currently on Resurrection remix Rom!
Thanks!
Fastboot command
adb reboot bootloader
fastboot oem fb_mode_set
fastboot oem fb_mode_clear
fastboot erase cache
fastboot reboot

Thanks!
I'll try this tomorrow.
Will update after I'm done!
Got the same problem - unlocked bootloader, installed TWRP, did dual sim mod for a friend and then the "idiot" did an ota - now phone is stuck into booting to TWRP.
I tried the fastboot commands and they went through fine, but phone is still only booting into twrp - with fastboot and "start" its booting up though.
There must still be some "do-ota" flag enabled somewhere.. ?!

EDIT: ok well **** it - after i booted it up once normal over the fastboot start it boots normal again!
+1 with same problem.

Can you give some more details on how you managed to fix it?
I have the same problem was on stock with root and tried OTA :silly:
These fastboot commands don't work for me, does anyone have another solution?

Perfect !!!
After flashing the android 8 version, my phone could not start normally (directly into the bootloader.)
The command lines saved my Moto lol ?
Thank you very much !

Moto Z Play reboot on TWRP instead of ROM (if I don't go by fastboot before booting)

Hi there,
I've got a problem with my Moto Z Play. It is unlocked with lastest unofficial TWRP, bootloader unlocked and running lastest Lineage OS ROM.
I already checked these type of threads:
https://forum.xda-developers.com/moto-z-play/help/booting-recovery-automatically-t3654698$
which gives a solution (doing some fastboot commands) but it doesn't work for me.
So I tried to do this in fastboot mode
" adb reboot bootloader
fastboot oem fb_mode_set
fastboot oem fb_mode_clear
fastboot erase cache
fastboot reboot "
But it didn't change anything. I need to boot on fastboot mode and then push power button while selecting start to get it runs on ROM.
Is anyone has a solution?

I faced the same issue ... Tried many things but simple solution worked like a charm
Flash twrp ... Re boot phone ... Don't boot to system instead boot to recovery ..then shutdown from recovery ... That's it twrp is permeant and phone boots to system normally
Tried this but still boots to recovery. Thanks for the idea.

today ,i tried blankflash_from_7.1NDX26.183-15_17.
then Found that BL model changed from MBM3.00-nash-sprint to MBM3.00-nash-verzion.
and can't enter blankflash mode anymore.The following methods have failed:

[HELP] Can't relock bootloader

So I've installed a custom ROM in a Moto G5s because was rebooting and lagging all time (sometimes reboot several times after start). But after the experience of a custom ROM, the problems persisted, so I decided return to the original firmware.
The thing is that I reinstalled the stock firm with CMD & fastboot, but I was not be able to unlock the bootloader (despite I used neccesary comands like fastboot oem fb_mode_set fastboot oem lock begin fastboot oem fb_mode_clear fastboot oem lock repeated times). So I download motorola RSD tool and flash it with it. The process was succesfull, but my bootloader still was unlocked.
What should I do? I missed any step?
Thanks
