I don’t know what happened to my phone, but I booted up the phone and I get the error in the picture below. The boot loader is locked and I can’t unlock it, it says “flashing unlock is not allowed “ and I can’t access download mode or any mode except boot loader.
So is there anyway to revive my phone again? Maybe force unlock boot loader or flashing stock bios using fastboot?
Thank you for your time.

You probably pressed power button which paused it from going further
That's the ugly Red safety warning, not the benign yellow one. As I understand, this is what happens if the bootloader is locked and one of the partitions fails its security check. All partitions must be completely stock when the bootloader is locked.
@runningnak3d described this somewhere, and I seem to recall it's a hard brick, or at least pretty hard. But I hope I'm wrong

I am in a messed up situation, I live outside US, asked a friend to bring me a nexus 9 from US. Tablet was ordered from Amazon, and when I received it its box was open. Anyway long story short when I turned on the tablet it showed me google logo then directly went to recovery screen (android logo with exclamation sign and text no command). This is all I get no matter how many times I restart the tablet.
I don't know how it got into this state, but I tried resetting it from recovery and fast boot, but it shows me same screen.
Boot loader is locked and I can not unlock it with unlock boot loader command, it tells me I don't have permission to run this command, now I know in nexus 9 you have to check a box in developer settings to run that command but the irony is I never reach the OS screen.
So I have locked boot loader, I am in a boot loop where my tablet boots into recovery by default, I can not unlock boot loader with simple unlock command, but I have access to boot loader and recovery and also ADB.
What option if any I have, is there any way to unlock boat loader without first checking that box in developer options, I really need help here other wise my money is going down the drain.

Can you get into recovery, when you get the exclamation mark use power + vol up? If you can do a factory reset in that

Yap, already tried that, but it did not fix any thing

Did you try a factory reset from the bootloader?

So I had a moto e with it's bootloader unlocked, and had a custom ROM running on it; however without my knowledge, someone gave the phone to a local (unauthorized )service center. I am not sure about what they did but after this incident, I get the Bootloader unlocked warning when it powers on, but then it directly goes to the fastboot menu saying that there was a fall through in the normal boot-up procedure, and 'system image validation failed'. However I was able to boot into android by rebooting a number of times. But recently, when it did boot up after several attempts the IMEI numbers were gone, so it wouldn't recognize my SIM cards.
I should also mention that the fastboot menu says that the phone is LOCKED. I tried using fastboot, but i cannot even get the unlock code info, or unlock the bootloader itself.
At this point, what do I do? Do I try flashing the same firmware again?
Thank You.
Try flashing the stock firmware :fingers-crossed: Best of Luck!
Hit Thanks if I Helped!!!!!!!!!!!
Is there a rooting section or something? I feel as if this may be in the wrong section (if so, please move it thanks)
So, today, I decided that I wanted to unlock, root, and install a custom ROM on my htc m9. Now, on my previous phone, I only rooted and installed a custom kernal, all of which were apps that I used on my phone to do all the work. for the m9, there are no apps that root the phone for you so I looked up a few tutorials. (I'll list what I did in case you find something I did wrong
list of my guides :
droidviews.com/root-htc-one-m9-marshmallow
.droidviews.com/how-to-root-htc-one-m9-and-install-twrp-recovery-on-it/
and I used htc dev to unlock my phone's bootloader
unlocking my bootloader.
Unlocking my bootloader was successful, when I go into download mode (the black screen to be clear) it says unlocked
installing twrp
There was a lot of issues when installing since all but one of the guides kept saying go into bootloader mode, bootloader mode this, bootloader mode that (which is the white screen). After some searching, I realized that they really meant download mode... two different things... I believe twrp was successfully downloaded since I am able to access twrp when I go into bootloader mode, then recovery mode, and I end up in twrp.
rooting
so, according to the guide, I move the supersu zip files into my internal storage (anywhere). then go into twrp, press install, select the zip file, then swipe to flash.
well, I did just that, however, when I go to turn on my phone, I get stuck on the htc load screen, It's not a boot loop, it's just that white screen that says htc... I can't do anything else. holding down the power button does nothing (even for 10 seconds)... update, after typing this, I get a nice animation, then I'm stuck on the white screen that says htc one...holding the power button again does nothing, power button, and volume down does nothing... I think if I hold the power button and volume up, I turn off the phone, meaning I can access download mode, boot loader mode, etc. So... now what? clearly, following instruction has got me not where (bummer) and my lack of experience has also gotten in trouble (it could be worse? right?) what can I do to fix this?
note: my previous phone, I soft bricked it and I was able to flash the stock rom with LG flash tool, but there's no such thing as htc flash tool...
Hi there,
I need your help with my device which I just bricked in a peculiar way...
So, something I flashed was not correct. That resulted in an infinite reboot loop (the logo is shown for half a second and it reboots... endlessly). I just used the volume-up rocker to go into fastboot mode to fix the thing as I usually do. I booted into fastboot and this is where it become weird: I cannot do anything!
If I try to use fastboot continue, the phone reboots endlessly again.
If I try to boot to any img (TWRP or signed recovery or signed boot), the device tells me it cannot because it is locked.
If I try to unlock the bootloader (again, because it was), I am told that I am not allowed to do it. The problem is that I cannot boot into a ROM to go into dev mode to allow this.
If I try to flash things, it obviously doesn't work either as the bootloader is considered locked.
The worse here is that since my phone is "not" hard-bricked, I cannot go into qhsusb_bulk mode and use Qualcomm tools to unbrick the thing.
Can I still do something myself or am I screwed?

Still you can do that hard brick recovery method it will work for sure..switch off your phone completely and try to connect qhsusb mode.
I had no idea that I could force the qhsusb mode. It worked indeed. Damn ARM devices with their non-standard way of doing anything...
Hi All,
I am currently in the phone repair business. Well i buy as much as i can fix and sell on. Its all fun. I have a very nice one currently and looking to see if anyone has ideas. All i want to do is boot to recovery that is my current goal.
So phone clearly has corrupt installation, likely a flash Rom or update gone wrong. It boots to Huawei logo then reboots and that's all it does. Tried de-powering and all sorts including removing battery cable but to no luck.
There is no recovery mode
No download mode
Can get to fastboot but unable to run commands it seems due to FRP lock. I am not worried about FRP lock at this time, i only want recovery back.
Tried:-
All flash commands and all fail
Any attempt to get to receovery or download mode fails
All three buttons to force SD card boot fails
Currently trying to boot using SD card but seems i need to change boot devices from within recovery. Well it has no recovery mode so no luck there.
So it is pretty much a brick at this point and could be a write off but before I give up does anyone have any other ideas? maybe a FB command i can run with FRP lock and bootloader lock on?
Thanks
Karl
