Hello all,
I am trying to install Cyanogenmod on my Nexus 10. I followed the instructions on the Cyanogenmod wiki (I can't link to them as a new user). I got as far as these instructions to unlock the device:
Enable USB debugging on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type the following to boot the device into fastboot mode:
Code:
$ adb reboot bootloader
From the same terminal, type the following command to unlock the bootloader (under Linux, you must be root):
Code:
$ fastboot oem unlock
A disclaimer will display on the device that must be accepted. Use the volume keys to cycle through the options. Pressing the power button should confirm your selection.
If the device doesn't automatically reboot, reboot it from the menu. It should now be unlocked. You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots.
However, the device never rebooted. It just shows the glowy nexus X logo indefinitely. If I reboot to the bootloader, I get options for recovery mode, however the device does not show up on fastboot or adb from my computer in recovery mode, so I don't know what to do.
I am new to the world of unlocking and custom roms and whatnot, and am worried that I just bricked my tablet . Thanks for reading.
OK, I found the answer searching online. A video on youtube explains it. The forum won't let me link the video, but the youtube id is T1Se7Hr9Cww. Put that after the "v=" in a youtube URL and you'll get there.
explains how to fix it. Evidently unlocking the boot loader doesn't reset the device, but the device must be reset to continue. So you need to do mash all the buttons in recovery mode to bring up a menu to delete your stuff.
I rooted my oneplus 2 some time ago to install the Screencast.app that there was on the oneplus one. I then after a while noticed that it started to perform worse than before i rooted it, so i decided to try to unroot it to fix the performance. But when i rebooted to fastboot and tried to flash the stock recovery, it said that the bootloader was locked. I then tried doing the unlock command (fastboot oem unlock), and it seemed to work (although - it didnt - in cmd it said finish but when i booted into bootloader again it was still locked) but when my phone tried to reboot, there was i quick flash of the oneplus logo and then the screen went blank. When i tried turning it off, i just rebooted and did the same thing. I could not boot into recovery either. The only thing i could do was booting into fastboot and from there i managed to use the command fastboot continue and restart my phone properly. So now i cant use my recovery to factory reset, i cant install a new recovery because the bootloader is locked, and now every time my phones powers off, i have to do the same thing with booting into fastboot and do the fastboot continue command to start it.
Can anyone tell me what the issues is here and how i can solve it?
I have the same problem, but once I got the phone to boot, I did a factory reset. Now I'm unable to even boot, literally the only thing that works is fastboot.
So my Nexus6p randomly restarted once (I had been on 7.0 since release date with no issues) and since then is stuck in bootloop on the Google Logo.
Holding the Power+Volume Down boots into bootloader. From there I can't get to recovery or even tried the factory reset from there and it always gets stuck on the Google Logo.
I have downloaded the SDK and while fastboot works, adb doesn't.
I can't flash anything through fastboot because boot loader is locked. I can't unlock the booatloader because remote oem unlock is disabled. I have never had the need to root or unlock bootloader, so never had USB debugging or allowing unlock checked under debugging tools.
Can't sideload OTAs since adb doesn't work.
Do I have any options to recover the device and make it work again?

Do you just have stock recovery? If so, can you boot directly into it with power + vol up. If so, maybe try hitting stock recovery menu to side load ADB or factory reset? Otherwise, sounds pretty borked unfortunately.

Try booting in TWRP and using the file manager to delete some user data to make space.

Can you use fastboot (volume down+power)? If you don't have Android SDK, then install Minimal ADB and Fastboot, open cmd in that directory and type "fastboot device" (or "fastboot devices"?) while phone is connected via USB in fastboot mode. If it displays your phone's serial number, then you can use fastboot. If it doesn't show you anything, then I think wiping your phone in recovery or performing a clean flash through Mi Flash is the only way. However, if you can use fastboot, then the next step would be booting into TWRP... but we'll get to that once you confirm if it's working or not.

Hi,
i have checked by typing command---fastboot reboot and my phone reboots and hangs at android one screen so that means i can use fastboot but strangely didnt see in fastboot devices but i found output for fastboot oem device-info where device unlocked shows false and other status.
If this is enough for using fastboot to boot into TWRP?

Actually bad news is that to boot into TWRP you need to unlock your bootloader first (fastboot oem unlock), but to do that I think you need to have enabled "OEM unlocking" in developer settings (though strangely I am unlocked, but for me this option is disabled). Try unlocking anyway. If it doesn't work, then I would follow this guide to clean flash official firmware with Mi Flash Tool. Be warned, you will lose all your data if you manage to unlock your device.

Hi,
Is that mean i will still loose all data even if i unlock bootloader?
And i am unable to unlock bootloader by command. So only option i have now to do factoryreset/wipe data?
So after factory reset again i need to flash the ROM ? Because if again i need to flash ROM, i understand the prerequisite is Bootloader unlock which will create issue again.
Please suggest.

Yes, unlocking bootloader wipes data.

No, if you wipe your phone through recovery you won't need to flash anything. It just deletes all your stuff without touching the system.

Guys pls help me i got stuck on boot logo i want to flash stock rom pls help me
I'm in the same boat. Unable to access developer options as phone won't boot and its stuck at the android one logo.
Fastboot oem unlock gives error Flashing Unlock is not allowed.
Is there anyway around this?
I'm still stuck with my Mi A2. I didn't enable OEM unlock or USB debugging and now i'm stuck on android one logo with only option is to boot into fast-boot mode. All commands and tools i try I get error stating unlock is not allowed in Lock State.
I bit the bullet and ordered an EDL cable so we'll see if i get anywhere with that. I've read that newer Xiaomi devices wont work with EDL cable and only option is to use the test point method....not sure how accurate that is but guess i'll find out whenever the cable gets here.

You can try fastboot oem edl
To put the phone in EDL mode without specific cable
However why not wipe data from the recovery?
Just use fastboot reboot recovery

If you see a triangle, you are in recovery mode
You need to press a button combination to see options, Search on Google for that
