My friend's Nexus 5x can't boot normaller neither in recovery, the bootloader is not unlocked. I tried a lot of things but is there a way to unlock the bootloader directly from it so I could flash a custom recovery?
Thanks

Can I flash stock image from Google's site without unlocking bootloader? My phone is defected and came without a recovery image in the software meaning I cannot update to 4.0.4 or perform factory wipes, so does this mean i cannot unlock bootloader? I need to unlock bootloader to flash stock 4.0.4 image correct?
The recovery and bootloader are seperate things. If you can boot into the bootloader you can unlock it. Hold down both volume up and down and power. It should boot you into the bootloader.
Yeah i'm pretty new to this so thanks for the response. I can get into fastboot mode by holding the power and volume buttons down but entering recovery mode does not work. I know that during the unlocking the bootloader process it causes a factory wipe, but theres no recovery image on my phone for my phone to revert back to, so what would happen?
You dont need to go into recovery to unlock your bootloader. You do it from fastboot itself. After unlocking you can flash the system image which includes the recovery.
Follow this tutorial: http://forum.xda-developers.com/showpost.php?p=25477039&postcount=1 It will walk you through the whole process.
Thanks a lot. Im in the middle of unlocking the bootloader now and that link will really help me flash the stock image. thanks!
No problem. If you get stuck either PM me or post to this thread again.
just unlocked bootloader and flashed stock 4.0.4 flawlessly. thanks for the help. fixed all my problems!
I unlocked my bootloader using Omnius but when I FASTBOOT flash a kernel I get stuck in a boot loop. I can flash back to stock kernels fine and access cwm. Am I missing a step? I have followed a lot of guides but most seem a bit out of date. How can I check that my boot loader is defiantly unlocked? Also, in-case I am being to impatient is it normal to wait 30 minutes for the first boot?
If you use flash tool for enter in fastboot?
Fastboot flash boot boot.img, check you're doing it correctly.

If you don't know, what you are doing, you shouldn't be doing it at all.

Just use the common way, like flashtool...
Oh and if custom kernel gets flashed without errors, then your bootloader is unlocked. If bootloader would be locked, kernel flashing would give an error.
I have a Nexus 5x H790, the bootloader is locked (by mistake), can't access the system beacuse it's have bootloader version BHZ11m, baseband M8994F-2.6.22.0.56 and i can't flash bootloader, radio, etc.
It get stuck on google logo.
thanks.

Edit
flashing an OTA update by the recovery solved the problem.

Hello Guys,
i have a redmi 5a and i made a rollback on rom from 10 to 9.
i had to unlock the bootloader and install previous verson of miui.
i could done that succesfully.
but i also installed twrp and root.
now i want to relock bootloader but when i do it via adb
not just the bootloader locks but the whole device too
and the phone does not start.
then i go back to fastboot and unlock the device with miflash unlock
and it works again but the bootloader is still open
what did i do wrong?
It's possible to relocked your device after rooting but relock the bootloader means locking the mod of your device, you'll lose your root. And again, if you need to root your device, you need to open the bootloader.
U cant relock the bootloader with custom recovery coz phone it doesnt start and maybe hard brick.always relock bootloader with stock recovery.also consider relocking,because u maybe cant unlock again until unofficial way found

Hi I lost my phone but my phone is locked with samsung id. Just wondering if any one can install custom recovery and custom rom without unlocking or if bootloader can be unlocked using adb or fastboot?
