[Q] Cannot access bootloader after rooting and unlocking bootloader - AT&T, Rogers HTC One X, Telstra One XL

I went through the process of rooting and then unlocking the bootloader based on this thread:
http://forum.xda-developers.com/showthread.php?t=1709424
And everything seems to be fine, I even installed CWM Recovery, but I can't load the bootloader to recovery mode or anything. I've turned off fast boot and am applying the power button + volume down key for at least a minute. Any ideas? Thanks for your help!

Try plugging your phone into your computer and adb into the bootloader using the command adb reboot bootloader. I have a hard time with the buttons but this always gets me into it.

Power button dead. Any way i can still unlock bootloader and root nexus 5

My power button is completely dead. I can neither switch off or switch on phone nor can i out it to sleep widout third party app.
I need to unlock bootloader and root phone but all methods need a working power button.. Any way i can do this widout power button jus by using pc and command window ?
Please help.. Em a noob..
U need To have the adb driver installed and fully working and the debug USB on.
Shutdown the phone by typing in the cmd "adb shell reboot -p"
When your device is off you now can keep pressing vol+ and vol- and plug a USB charger keep pressing the buttons until the fastboot menu starts; now u can use fastboot commands To unlock the bootloader. When the phone reboot it self you need To go to developer options and re-activate the debug USB; don't let the screen turn off cause if this happened your devices is died.
Now restart the procedure and re-enter the fastboot menu.
By typing "fastboot reboot recovery " you will have the access To the recovery and u can flash the super su module

Hi to to select unlocking of bootloader i have to select 'yes' but power button aint working. Can you guide ib detail how to unlock bootloader widout power button
I normally don't suggest anything but fastboot however if you aren't concerned about issues and bootloops with modifying your phone... Check out towelroot. You should be able to root without unlocking your bootloader and you can use adb on your PC to reboot. After root use terminal emulator on your device for reboots if needed.

Root with towelroot as previously suggested. Then get bootunlocker from the play store.

BLU Studio One Plus Unlocking Bootloader

Bought this device and everything works great and I have root. When I try to unlock the boot loader by going to "Developer Options" and checking the "Oem Unlock", I then
Code:
adb reboot-bootloader
At this point I do a
Code:
fastboot oem unlock
Which then the device asks me to use the volume buttons to confirm, Volume up for yes and volume down for no. The problem I'm running into is in fastboot mode it seems my volume up and power key are completely ignored. They work in recovery and in android but not in the boot loader itself.
I have tried unplugging the phone after sending the command over to see if that is a factor but it doesn't seem so. I'm only allowed to use volume down which denies unlocking the boot loader.
Another thing if anybody can get me a scatter file that would be much appreciated.

How did you root the phone?
Hoping for an answer to the bootloader question as well. For root I'm going to attempt kingoroot and replace with supersu

Nexus 5 Bootloop, Bootloader locked, No recovery, No root, No Emergency Mode...Help!!

Ive been asked by a friend of mine to fix his nexus 5 that is stuck on a Bootloop, I've opened it up to have a look at the power button and that wasn't the problem, the device has not been rooted, the Bootloader is locked, there is no emergency mode and there is no recovery. I am however able to access fastboot and when I try unlocking via fast boot it does unlock but then requires a full reboot and as I've said before this cannot happen because of the Bootloop.
Any suggestions!?!?!?!
After unlocking the bootloader, does the bootloader relock itself? If it does, the memory chip is damaged and requires a replacement motherboard.
I've had this problem when I corrupted my recovery by using FlashFire and my bootloader was locked. Though I was able to restore my device using Fastboot. I had unlocked my device and instead of flashing the stock recovery when unlocking the bootloader I had flashed the Team Win Recovery Project recovery and when I tried to boot up to TWRP recovery it would stay for a couple of second displaying that it couldn't wipe the data partition and then reboot me back into bootloader mode. I fixed that when trying out the following steps:
1= Download the latest firmware of the device found Here .
2= Boot the device to Fastboot mode (aka Bootloader mode) plug the device in and unlock the bootloader (of coarse confirm when asked by the device).
3= After seeing that the device has stopped wiping data indicated the text "wiping..." in the very bottom of the specifications in the Fastboot Bootloader REBOOT THE DEVICE IN FASTBOOT BOOTLOADER MODE by navigating using Volume buttons to scroll down and highlight the option "Reboot Bootloader" and then pressing the Power button.
4= Using the provided scripts for Windows , Mac and Linux flash the device with the firmware.
VERY IMPORTANT: WHEN YOU SEE THAT IT IS FLASHING "userdata" and after that "cache" HOLD DOWN THE VOLUME DOWN BUTTON THIS WILL FORCE THE DEVICE INTO FASTBOOT BOOTLOADER MODE.
5= When you see that the device is in the Fastboot Bootloader mode scroll down (again using volume buttons) and highlight "Recovery Mode" then boot into Recovery and it should automatically start wiping the ("userdata" partition) Data once more that the bootloader said when it displayed the "wiping..." message after being unlocked.
If not wipe data factory reset the device manually by using the recovery and reboot to the system.
Optional: 6= IF the device has successfully booted up power it back down and lock the bootloader again using the fastboot tool additionally before locking the bootloader you can reset the warranty tamper flags.
This tutorial explains in detail how to flash a firmware to the Nexus 5 and shows how to restore the tamper flags.
I hope that I helped in some way.

Yes after unlocking Bootloader and restarting the device into the Bootloader it relocks and I'm back at square one
The motherboard needs to be changed. I recommend looking for a used Nexus 5 with a smashed screen and a working motherboard as this may easier than trying to find a new motherboard.

Thanks for the suggestion but I've tried this already and it doesn't work because when I unlock the bootloader and reboot into the Bootloader it locks itself again making impossible to flash the system image

No download mode - LG Mobile Driver problem?

Hello, I have problem with my softbricked Nexus 5.
phone is full stock
bootloader is locked
USB debugging is not enabled
Android 6.0.1
all buttons are working
USB socket is fine
Factory reset from recovery mode is not working - still bootlooping
My purpose is to bring it to live, but I am stuck. Due to locked bootloader I have to use LG Flash Tool. Some time ago I used it with my other Nexus 5 and it was fine - worked excellent. Now I want to do it again with other phone but I am stuck on start: Can't enter download mode (volume up+usb cable). When I am trying to enter to download mode,charging battery icon appears and after few seconds my phone is being recognized as MTP USB device in device manager. I thought it is a problem with the phone, but tried with another working Nexus and there is no difference - it looks like problem with phone-pc connection to me. I tried few cables (original samsung and nokia) and two pc's - no difference. Tried all USB ports etc. Clean reinstall (with registry keys delete) doesn't help, updated version 4.2 neither. Do you have any ideas how to fix it?
Download mode? Never heard of that on the Nexus 5. There is a fastboot mode for flashing stock ROMs and to unlock the bootloader.
I recommend unlocking the bootloader and using NRT to flash a stock ROM.

I have NRT but problem is that to unlock bootloader I have to enable USB debugging - I can't do it with bootlooping phone.
Bootloader can be unlocked without enabling debugging as you are not running adb commands, you need to run fastboot commands.

Thanks! Can I do it with NRT also?
Easiest way to unlock the bootloader on a windows machine is to do this:
make sure that the necessary fast boot drivers are installed;
boot phone into fast boot mode by holding down volume up, volume down, and power;
connect the phone to the computer;
type "fastboot oem unlock" without the quotation marks and press enter key.
Unlocking will wipe the phone.
Once unlocked, you can flash a stock ROM using fastboot commands.

Ok I did it. Do I have to proceed "fastboot reboot" command? when I am doing it it reboots and still bootlooping. When I enter bootloader it is locked again
If the bootloader relocks itself when the phone is rebooted, the memory chip is damaged and will need a motherboard replacement.

Soyes 7S, any idea how to unlock/flash/root?

Got this phone today, can't get it to boot into fastboot or recovery - volup+power, volup+home+power, volup+voldown+power nothing seems to work and the phone just boots normally.
Also can't find which android drivers to use, or a reliable source of the apk to flash it.
Any suggestions?
Can get into fastboot via the command line, I guess I had the right drivers already. But can't unlock the bootloader because the volume up to unlock doesn't work, it doesn't recognise the button press.
Kingoroot won't work, likely because the bootloader is locked but not certain on that.
Try it maby
Try to enable the hidden developer setting and enabling ome unlock And then flash a recovery or a rotting file via Odin 3 sorry for bad spelling im 12 + I think that will unlock the bootloader and you can try kingroot , kingoroot and super one click
I have the version with 6.0 firmware, which doesnt unlock bootloader since the vol up does nothing on fastboot. Any solutions were found? Gratitude
