Accidentally relocked the bootloader before flashing system files provided by Google (flash-all)
Now I'm getting a message that the system files are corrupted and I can not get into recovery or unlock my bootloader.
Any help would be appreciated.
red screen or yellow warning screen.. if red and if you can still use fastboot there is a continue command that allows you to boot the phone up..then booted go into developers options, toggle oem locking and then boot back into bootloader and unlock again

Whoops, accidentally provided useless advice. Please disregard.

I am trying to unlock the bootloader on my wife's 1st gen moto g, using the method on Motorola's website:
fastboot oem unlock UNIQUE_KEY
copy and paste UNIQUE_KEY to the website
fastboot oem unlock UNLOCK_KEY
At this point, the site says:
"If the line was entered correctly, you will see a message confirming that your device was unlocked.
Congratulations! Your device will now reboot..."
Except the phone is just sitting at a black screen with "Unlock..." in blue. Should I just force a reboot or leave it for a while (its been about 10 minutes already)?
EDIT - I pressed the vol up button and this executed the command. How do I get rid of the unlocked bootloader warning splash screen now?
You can flash a new logo.bin file using fastboot.

I have Nexus 5 phone which was not turning on a few days back. I kept it aside so that battery drains fully.
Now when I turn on the phone, it is on Google Logo Boot-Loop. When I press Power and Volume Down, I can boot into fastboot mode.
In fastboot mode, the device says it is locked and i send the following commands:
fastboot devices
fastboot oem unlock (Select Yes on Screen and Confirm as well)
fastboot reboot
Click to expand...
Click to collapse
After this, ideally the bootloader should be unlocked, but the phone still remains in boot loop and when put into fastboot mode, it again shows device is locked.
I don't know what all is happening. Is there anything I can try now? Even fastboot boot recover.img is not working as phone boots into custom recovery for some time and then reboots automatically.
I kept my phone on charge for a few mins and when I came back to unplug, it was stuck on google screen. tried turning off the device or restarting it but nothing works. The phone was extremely hot. My phone is completely factory stock. the bootloader is locked too. how to recover it now ? please help.
i tried entering recovery mode but as soon as i select recovery it gets back to google logo screen again.
right now i have kept the phone in freezer now.
my bootloader is locked .. can i still unlock it and flash factory image ?
help ?
not a single reply ? bump...
Are you able to communicate with the device using fastboot?
Try flashing the stock images via fastboot
You won't need an unlocked bootloader for this

Try the instructions at the top of the page here https://developers.google.com/android/images
It may work without unlocking the bootloader.

whatever command i use it says OEM unlock is not allowed.
Just throwing out ideas that you may have already tried. If I understand right you cannot get into recovery which eliminates trying to sideload the stock image. Your bootloader is locked and it will not let you unlock so booting into TWRP is out of the question. Are you just wanting your phone operational again? Have you tried wiping/factory resetting with fastboot commands? i.e. fastboot erase userdata or fastboot format userdata.

yes i have tried flashing by giving the fastboot command "flash-all.bat" it starts flashing and it stops in the initial stage by giving error " restarting bootloader" then I get 2nd error " bootloader locked" and process repeats again

both command not working .. same bootloader locked message.
error message " Please unlock the device to activate this command"
anyone else can help ?
I would contact Google customer support. Even though my phone was out of warranty and I was not the original buyer (bought in eBay), they were willing to make a one-time exception for an RMA. I didn't use it because my phone is rooted and I was afraid of being charged for any repairs. As long as your phone is stock and unrooted, you have a chance. Just say that you think you have a hardware failure and while you understand that they are in no obligation to help, you would appreciate anything they can do.

If the "orange state" is "Your device is unlocked and cannot be trusted", you will most likely have your bootloader unlocked.

So what to do I need to lock my bootloader
No need to relock. What happens when you presses the button combination of fastboot mode (search Google)?

Take note that as soon as you re-lock the bootloader the bootloader simply gets forced to load phone's Stock ROM.

Hey there,
I have a Pixel 3a, which refuses to start. After powering on, it directly hangs on the first google logo forever.
The device has stock rom and a locked bootloader.
I can still enter fastboot, but when I try to enter recovery mode from there I'm stuck at the google logo again.
Is there anything left I can do to revive the device?
- I cannot unlock the bootloader, because I need to the check this oem unlock setting which in turn is not possible whithout a working device. Or is there a different way?
- I cannot switch the A/B slot because the device is locked.
- I cannot flash something because the device is locked.
I'm grateful for any advice.

Hi there.
A couple of questions first:
Does it respond to any adb or fastboot commands?
Does it enter into Recovery or Rescue mode from Fastboot?
If yes, then your best bet is either https://pixelrepair.withgoogle.com/ or https://flash.android.com/
Both tools should work even with a locked bootloader, you just need Chrome and the USB driver.
Be warned tho, both tools will erase and factory reset your phone.
