okay, open up a command prompt, plug in your phone while in bootloader.
type this:
fastboot oem unlock
then hit yes, it should work...

Thanks friend :good:
i saw this issue with my friend´s n4.
he re flashed stock 4.2(yea 4.2, google it, its not 4.2.2) and tried again doin fastboot oem unlock and then fastboot format userdata.
but if dosent work, you can reflash the n4 using lgnpst. or even flash the beta bootloader found on n4´s .tot.
if still dosent work i can make a system.img with root so you can use one of those apps to unlock it.

recovery before wipe
After wipe
well then it seems your internal memory is fried, since it can't even wipe the phone. or its a corruption from a failed wipe made by the bootloader. since its still locked, you can't really do much with the bootloader... just stating facts here

Hey everyone,
I am using the DROID RAZR M Utility 1.20, as posted here:
http://forum.xda-developers.com/showthread.php?t=2249773
I also followed the youtube video of it, as posted here:
http://youtu.be/ej7HBxvNPv0 (The video is actually for the Razr HD but the process is basically the same.)
Here is what I did.
Powered up phone in AP Fast Boot, and did step 1.) Flash 4.1.2 Stock System.
Then rebooted phone into Normal Mode (USB Debugger is on) and ran option 5.) Motochopper Root Exploit.
It rooted successfully.
Ten i ran Step 6.) Unlock Bootloader (Motopocalypse), ran the App, and it says it was successful.
Then I Ran step 4. ) Flash CWM Custom Recovery.
after this i rebooted the phone and went into the Recovery mode, but the only thing im getting is the little android on his back with the alert sign:
{

I am not sure what to do next? I am trying to load the Cyanogenmod onto this Droid Razr M, but safestrap evidently is not going to do it for me.
Any help is appreciated.
Thanks!
quick update..
Appears that Step6 is not working.
After rebooting into AP Fastboot, it says the Device is Locked.
Anyother tools out there to unlock the bootloader?

Motopocalypse is the only tool to unlock the BL. You can find it stand-alone if you do a quick Google search. However, if you were on the latest update, you won't be able to unlock your BL, even if you revert back to the older version. You can root with Motochopper 1.3, though.
Also, that screen is the stock recovery screen. When you're in that screen, hold vol down and tap vol up to get into recovery. If in fact you can unlock your bootloader and you succeed and you flash CWM recovery, you'll need to reboot immediately into recovery so the CWM updater script can finish its install. Otherwise, the stock recovery will override.
So if the phone has ever been updated OTA to the latest version, unlocking the bootloader is a lost cause?
That really sticks because i think this phone was updated.
I have verified the phone is rooted - otherwise safestrap wouldn't work.
So phone is rooted - what your saying is, using that tool - run the CWM Script, then reboot the phone and go directly to the recovery screen, then hold the Volume Down button, then press the Volume Up button..?
I will give this a try.
Thanks!

Yeah, unfortunately, if it was ever updated, you can't unlock the BL. Even reverting back still won't open the "trusted zone." You can verify if Motopocalypse worked by booting back into the Fastboot screen. It should say the phone's unlocked. If you can get it unlocked, then yeah, immediately power off phone after flashing recovery and then reboot straight into recovery. If script ran as it should, you should boot straight into CWM.

Well i think im at a dead-end. :-/
Fastboot keeps saying Device is LOCKED. I cannot get it to unlock... Argh!
Any other way ? Is it possible to revert or modify the "trusted zone"?

Huh. There is no information on your post. What do you think XDA is? Can't help until you tell your situation.
Nobody can solve your problem until you explain what happened.

I got OP2 from friend. He used Oxygen 2.x (don't know exactly) and decided to flash some custom ROM. And something went wrong
He brought me today his phone and:
- fastboot works,
- device is locked and impossible tu unlock (FAILED (remote: oem unlock is disabled))
- after 2 hours of work I got stock recovery working (using some Chinese Qualcomm recovery tool).
But: I can't unlock BL, I can't flash anything via fastboot (because ->locked), ADB doesn't work too (cant push any file to devices).
When turning on phone it's in bootloop, but I can enter fastboot or stock recovery.
I tried almost all solutions from her and OP forums, but everything false because of locked BL.
ANY ideas? My short knowledge ends here There is probably no any data in device (no system, userdata etc.).
I don't have USB-C pendrive / cable so I cant flash anything from stock recovery. If I'll get USB-C pendrive will it be possible to flash stock ROM with stock recovery?
Does it show up in fastboot devices?

It sounds like the ability to unlock the bootloader is disabled in developer options. I think, but I'm only guessing.

Yes, but I can't boot to system (probably memory is empty- no data) and switch OEM Unlock.
I've got only fastboot and stock recovery.
do any of these help you? I guess you could say your phone is hard bricked due to not booting to OS and not having TWRP recovery?

Fastboot this, it will DELETE EVERYTHING(no exceptions) (maybe except firmware) and install seraph08's cm13.
https://s.basketbuild.com/devs/Seraph08/oneplus2/fastboot img files
or flash stock OOS2.x official via stock recovery(if MTP or ADB works in stock recovery)
No idea about USB OTG, try dont buy. Might work in TWRP, dont think itll work on stock
or try the soft brick recovery on his basketbuild or other various available threads
Edit: you said fastboot works and then you said it doesnt work, confirm.
I used other PC and other tool including system.bin and userdata.bin. And it finally worked. Unbricked

It seems that the boot image was lost or erased on your phone, at least you still keep the Bootloader right? it's still alive, so there's a way to solve it, yet, this means the procedure may be hard, but you can make it boot again but your files will be erased since flashing a rom by fastboot usually clears all User Data, follow the steps from here https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 but Skip the Blank Flash files, you won't need them (thankfully) I hope this solve your problem

Since the Link contains the Stock Moto G4/G4 Plus rom, you shouldn't have any problem with the Bootloader being locked or unlocked, so try it out and hopefully it will make Android boot once again

As the message says, it can't find a bootlogo. (usually logo.bin). If you've got a locked bootloader, you must have all key partitions, including logo.bin on the same patch level (and as such you may have to flash all partitions).
Which firmware did you try to flash and what flashing commands did you use, and can you show us the outputs of said commands?

Make sure you have unlocked the bootloader AND unlocked critical partitions, then flash the latest factory image found on essentials support page. DO NOT flash TWRP or anything like that.

How do I unlock critical partitions? Also I have already flashed TWRP. If I try to push the factory image without TWRP it tells me not enough space.
I suspect you need to change the slot that's loading... I had a similar thing recently. .. Try going into fastboot and typing "fastboot --set-active=slot" where slot is "a" or "b", depending on where you flashed TWRP (you need to load the opposite slot).
If that doesn't work, flash the original boot file in fastboot and keep everything crossed...!

flash OTA via adb sideload , it will fix your issue
Just do the fastboot flashall from the Essential download page and start over. I flashed the october update the other day and my phone has been running so much better since then.

Instructions are on the Essential website where you can grab the downloads. Basically download the fastboot image, unzip it and run the flashall script inside the unzip. Easier if your fastboot path is setup properly. It will flash stock to both slots and away you go.
You NEED to unlock critical partitions to flash all of them.

via MiUnlocker the unlock gets to de 50% and gives an error and on its logs it says: Remote: oem unlock is not allowed
I tryed to flash TWRP with command fastboot flash recovery but the error is the same: remote: partition flashing is not allowed
Can anyone help me please??
I'm stuck on the bootloop i can't go to setting - developer - allow oem unlock option!!
Have you tried doing a Factory Reset from stock recovery?
This is a strange behavior, even if an OTA update corrupted the system for some reason, the phone should boot from the original slot.
Have you tried switching slots manually from fastboot ?

Hello!
I've faced the exact same problem yesterday.
You need to force the phone to boot in EDL mode by opening the back cover and short circuit 2 pins as shown in THIS video.
After you have the phone in EDL and being detected by your PC (you need the correct drivers, you may get them on THIS thread by @CosmicDan), you may use MiFlash Tool to flash official PIE Rom, access developer options and enable oem unlock to be able to unlock your phone again.
If you wish to revert to Oreo, please use THIS guide.
Cheers!

Hello!
I've faced the exact same problem yesterday.
You need to force the phone to boot in EDL mode by opening the back cover and short circuit 2 pins as shown in THIS video.
After you have the phone in EDL and being detected by your PC (you need the correct drivers, you may get them on THIS thread by @CosmicDan), you may use MiFlash Tool to flash official PIE Rom, access developer options and enable oem unlock to be able to unlock your phone again.
If you wish to revert to Oreo, please use THIS guide.
Cheers!

Actually you have a recovery. You need to long press the power button and, afterwards (not at the same time), press the volume + button. You'll see that all options will appear.
