well my nexus 7 was rooted for a long time and it was always a good tablet but one day i played around with it after an update i didn't tipe fastboot oem unlock but fastboot oem lock so i locked my bootloader by accident and with not even knowing that i did this mistake
but without a stock recovery.img, no stock system pretty much nothing stock but with twrp recovery and paranoid android on it, when i tryed to go to recovery with no error but it couldn't mount enything
when with the sdk tools i tryed to format everything and that even worked
then i looked at my bootloader that it was locked so i tryed to unlock it with no success, and pretty much the other 20 times :silly:, and i even tryed tools like N-Cry, well still (it went fine but going on with a black screen and bootloader still saying locked maybe because no system is there so no ADB mode to go in) or (saying unlocking... in the upper left corner of the bootloader and doing nothing else)
so my question is if there is a way to fix it

Can't find an example of this happening to anyone else, but it seems to be a difficult problem to search for since any possible fix appears to require that the problem I'm having not exist.
Basics: bootloader is unlocked, but otherwise everything is stock, NOT rooted.
Had a hard lockup a couple of days ago and any attempt to reboot would just get stuck at the Google logo. Even waiting for over an hour, it just wouldn't move on. Went into the bootloader, which was also acting weird, hanging up and just not working properly. A search indicated that the best thing to do is just grab the factory images from Google and use fastboot to re-flash the bootloader image (checksum was verified before I attempted to flash). That process went ok and "fastboot reboot-bootloader" sent to a nice and properly working bootloader. I used fastboot again to load up TWRP (via the "boot" command) to do a backup, and then rebooted back into the bootloader from TWRP. At this point it went fubar.
The screen will show just the up and down arrows for a couple of seconds, then the entire screen goes grey. Neither fastboot nor adb will see the tablet when in the bootloader and my only option seems to be to just hold the power button down and force a restart.
Luckily the original problem did get fixed with this process and it boots up fine now and works perfectly otherwise. adb does work fine when not in the bootloader, and I can use adb to restart into recovery which also works fine. It's just that the bootloader gives me nothing usable.
I'm not going to try and RMA for something that was obviously my fault, and the tablet works fine now except for the bootloader, but I'm sure that I'll want/need it fixed at some point. Does anyone have any suggestions for attempting to fix this, or am I just screwed?
Okay, so there is no screen protector or anything. Not rooted or unlocked or tampered in any way. I've had the phone for 26 hours and then the following happened:
EDIT: YouTube video added https://youtu.be/yAVmTz7MQbQ
I pulled the phone out of my pocket to unlock it. I see the lock screen and put in my pin (yes, I see the actual screen and stuff on it. Let me make that clear.) after I enter my pin successfully the screen locks itself. I contacted Google support and they said to factory reset it. I did the full factory data reset in the recovery mode (again, the screen works. I can see everything to do a FDR and I can see the boot animation) and it starts to boot up. Once I see the "welcome" screen it instantly locks itself. I can hear the audible "latch" locking sound that it makes when you press the power button. I know the buttons are not malfunctioning because they work perfectly fine in bootloader / recovery mode to scroll up and down and select things. I've tried multiple things but nothing seems to work. The problem here is that I want to try and do a factory image but my computer will NOT recognize my Nexus 6P when in recovery mode / bootloader mode. I have all the drivers installed but since I can't access the OS and enable OEM UNLOCKING there is no way to factory flash a factory image is there? Can someone maybe help point me in the right direction? Again, I can NOT access the OS at all whatsoever.
You just need the bootloader unlocked to flash a factory image, you can't enable that from settings o.0 so I guess your down to RMA now.
The command is now "fastboot flashing unlock"
Hey downloading a tool kit from this devices tools sections. Install the latest adb / fastboot binarys and try again
Good luck !

Hi Hutzdani, when I try to run the command it says "remote: oem unlock is not allowed". I have the RMA in progress but 3-5 days with no phone is going to become grueling unfortunately and I want to try everything I can. :S

Can you run fastboot format cache and format user data? Then will anything happen ?
Sounds like you need to edit the partition that holds the data change for allow OEM unlock - there's a few threads about this on XDA for the N9 and N6 as far as I can remember.
It would seem the ability to flash a fresh system.img would solve this
ive ran into a big problem. i had my OP2 rooted and loaded with CM12. Recently i wanted to revert back to stock to receive all the updates for the phone and in the process of reversing everything, i've managed to lose everything as i was expecting when i was initially going to. Now the bootloader will not unlock with using "fastboot oem unlock". The phone restarts out of fastboot to the 1+ logo then black screen or just sits in a constant boot loop.
Any and all help will be greatly appreciated.
It's sad no one answered your post u know I'm going thru the same problem
Done everything like enable OEM unlock and USB Debugging in developer settings?
Wife's phone got stuck in a bootloop last night, just stayed on the moto logo. Tried wiping cache and then data from recovery. phone now boots to moto then a black screen. I can see the device in fastboot, but not in recovery. I want to unlock the phone so that I can reflash the OS either from a custom recovery or from fastboot, but since I cant fully boot, I cant get to the developer options. This phone has never been unlocked/rooted or anything.
Is there a way to unlock the bootloader without going into the developer options and enabling it?

No there is no way to unlock bootloader without allowing OEM unlock, you're gonna wanna flash the latest version of stock available for your phone. Unfortunately I'm not very familiar with the commands so maybe another user can chime in here!

You cannot unlock BL without "allow oem unlock" enabled.
Usb debugging you can't enable with fastboot.
You can try to erase with commands:
fastboot erase userdata
fastboot erase cache
fastboot erase customize
fastboot reboot
Give it some time.
How long are you waiting for it to boot after a factory reset? This can take 30 minutes... sometimes more.

I've waited at least 20 mins (not really timing it.) but with the black screen (screen on, not displaying anything) after the boot screen, how can I be sure its actually doing anything?
Honestly... Locked and stock there isn't much you can do. If we had the latest firmware image, maybe, but we are a release behind with no way knowing when, or if, we will ever get the current one.
There are two likely cases here for the cause of this problem... Actually, the cause is corruption of data on the internal emmc chip, the reason behind that corruption is the issue. It is either a faulty emmc chip or a fluke from cosmic radiation, static electricity, or who knows what. Either way, there since a factory reset isn't fixing it and we don't have a current firmware image your only option is send it in to Moto or replace it.
Hi, just bought a phone for my son secondhand, it's going to be sold again if I can't fix this! The phone was sold cheap as it had software issues (of course) so I figured I could fix these and get it going (install custom recovery, ROM etc). I'm slightly stumped at the moment, so maybe you can help me.
The phone's defaulting to the bootloader screen, lots of info on this but the key thing I noticed was that it says 'the device is locked status code: 2'.
Clicking 'start' takes me a 'warning unlocked bootloader screen' then it runs through the 'hello moto' startup screen and back to bootloader
Clicking 'recovery' - there is definitely no working recovery on it, I just a get the dead robot with 'no command' underneath.
Clicking 'Factory Mode' allows me so far through the startup (after the bootloader unlocked warning), and you can get so far through setting it up, but because the battery is so low (it's permanently on with the bootloader when plugged in) it never seems to charge up enough, and either way the screen freezes at or around the final setup steps and then it reverts back to bootloader. I thought if I got into developer options and security, I could enable the USB debugging, OEM unlock etc, but no go there.
I've installed Motorola USB drivers but it doesn't seem to be registering on the PC (Windows 10).
There is some suggestion on other forums (less reputable!) that the locked status code may mean the bootloader has been relocked, but this seems contrary to what the phone is telling me.
Any ideas welcome, thanks - it's a lovely phone, just not much use at the moment.

OK, some progress, I have now unlocked the bootloader, so have the UNLOCKED Status Code:3 which is good, unfortunately has not yet helped with my issues. I can't use ADB, but MFastboot tool is working, so can run commands from that (hence me getting to that stage). Tried reinstalling firmware, may try and do this again now bootloader unlocked....
slightly further along...

I have now managed to flash stock firmwares using Mfastboot tool, but hasn't unfortunately fixed the boot up issues. However, I have now worked out how to access the recovery, by reading other posts on different Motorola phones:
boot to bootloader, power+vol down
in bootloader select recovery using the volume up/down buttons, press power button to select
phone boots into 'recovery,' showing the dead android with no command
at this point hold down the power and volume up, then release volume up but keep power held down
phones boots, by magic, into android recovery, where you can factory reset, wipe cache adb sideload and install from SD card
I now need to try and get a flashable recovery to sideload, as the attempts to flash it don't work for me. The OS I seem to be on is reteu 7.1.1, so I will try and go for a lower version, and see if that allows me to flash the custom recovery I desperately need.
But....things are improving slowly....:laugh:

OK thanks, I read that, but didn't realise it was a thing....should I be able to sideload a custom rom using ADB?
