Fastboot/Recovery/ADB Without Power Button and Volume Down?

My power volume down buttons don't work and I'm locked out of the phone. I can boot it up via USB when connected to a computer but USB debugging isn't enabled so I can't use ADB. Is there any way to wipe the phone without the power button and volume down key?
thanks.

Turn on USB debugging?
Solves problem #1
adb reboot bootloader

There's a pattern lock and I don't know it or the gmail info. I need to either find a way to boot into fastboot/recovery or find a way to turn on USB debugging without getting into the phone. Unless someone has a shortcut method to just wipe the phone back to factory settings.

[Q] Root jelly bean verizon galaxy nexus phone without using the power button?

My power button died, and I'm trying to deal with it, found my way here about rooting the phone. It seems like all the instructions require the power button to select a mode or something. Is there a way to root the phone without the power button so I can use sweep to wake?

activate adb debugging mode , then go to command prompt and type either "adb reboot bootloader " or "adb reboot recovery" to enter either mode without power button .

Thanks! I tried, but in order to unlock the bootloader, I have to press the power button to continue?

i think that can help .

You could possibly do this.

thanks, I have a mac so I couldn't do the latter, and the former I have a newer version. fml

you can always flash back to a older firmware using toolkits

[Q] I can't access Bootloader or Recovery PLEASE Help!

My HTC One M8 (Verizon) is seemingly bricked. My phone is rooted, S-Off, with the stock ROM. I have been trying to update to the latest OTA update by returning to stock. I had previously modified some entries in the Build.prop and Platform.xml. I knew those had to be default in order for the OTA to work. I had copied the original files and pasted them to my SD Card so that I could simply cut the modified versions, paste them to my SD Card, and cut the originals from my SD Card and put them in their corresponding system folders.
Upon a reboot something apparently went horribly wrong because all my phone does now is boot with the white screen and green HTC Logo, then the screen goes black. I have tried the typical Power Button + Volume Down but it won't enter the boot loader. The good news is that the USB port seems to still work for my windows computer recognizes a device connecting to it but it doesn't show up as an interactive device in windows explorer..if that makes sense.
Please Help!

When you connect it to the PC can you pick up the device with adb? If so, have you tried to run the command from adb to boot it into bootloader? adb devices ... if found, adb reboot bootloader
:fingers-crossed:

I'm not too familiar with ADB commands but I typed in "adb reboot recovery" and it said: "error: device not found" so even if my command was wrong it's still not detecting it. I also tried: "fastboot reboot bootloader" and it just says "waiting for device"
Also I feel like it's worth mentioning the phone is automatically rebooting every two minutes or so (haven't timed it exactly but it's a while). Still showing the green HTC Logo then the screen goes dim, then the screen turns off.

Try holding volume UP + Power button, this simulates a "battery pull", just hold it in for a while it can take a while to "pull", when it's off try again booting into bootloader, volume DOWN + Power button.

I held Volume Up + Power Button and it showed the white screen with the green HTC logo. I then released all buttons. Once the screen turned off I then held Volume Down + Power Button for two minutes straight and nothing happened.
Even though we haven't found a solution yet, I am appreciative of the help.

sounds like you never installed the htc drivers for your phone, hence your pc doesn't see the phone when you are doing ADB commands.
install the drivers for it, then try the ADB commands via your pc
and dont mess with the build prop or other system files unless you have a working back up and are 101% certain about what you are doing..

Just remember to change directory in command prompt to the folder where adb.exe is located.
I don't know why the device doesn't reboot into bootloader though when you hold volume down + power button, shouldn't have to hold it for 2minutes. Holding volume up + power button to simulate a "pull" should only take up to 20 seconds or so at most and pressing volume down + power will then immediately take you into bootloader mode, or at least it's supposed to.
Did you release the volume up / power combo when the screen went dead or before? Try holding it until the phone shuts off and then right away press volume down + power.
Sorry if I'm not answering right away though, busy eating, and will be here and away for the next hour or so while I get ready for work =o( once I leave for work I'll only be able to help some more after like 2 hours or so. Hopefully we can do something before then though =o)

You're right, I didn't install the drivers. I did so and ADB was able to recognize it and I was able to access the bootloader. Thank you everyone for your help. I won't be making the mistake again.

So you'll be able to fix it from here on then? I was just about to link this thread to you as well should you have gotten adb to work again, it's for the RUU for Verizon seeing as you said you're on Verizon.
But going by your response up there you might already know how to fix this issue further :good:

Indeed I appreciate it, but I just finished installing the RUU ha. Hopefully this thread will be of use to someone in a similar circumstance in the future.

Share another method of getting into recovery mode on non-responsive blank screen
Hi,
I just want to share how I accessed recovery mode with the same build.prop issue but with S-ON (might work with S-Off too).
I found the solution from here:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
To get into recovery mode on a non-responsive blank screen, hold the power button and volume up button at the same time and then approximately after 10 seconds, switch from pressing the volume up to volume down button before the HTC logo white screen shows while still holding down the power button. After, a white boot screen will give an option to go into recovery mode.

[Q] HTC Desire bricked, Vol Down button broken

I have this HTC Desire I'm trying to get back to work. I bricked it about a year ago but I'd like to use it as a spare phone.
When I try to boot the phone, nothing happens. When I boot while charging, the orange led goes out for a few seconds, so the power button press is registered. However, the screen just stays black.
I've been reading methods for flashing recovery using fastboot, but booting into fastboot requires to press the Vol. Down key, which is no longer working on the device.
Is there any way to fix this phone? I'm on a Linux machine and have Android SDK tools installed, however, I have little experience with flashing software (read: I only did it by copy-pasting pre-made commands).
Many thanks in advance!
Steven

Turn the phone on and keep pressing back and it should take you to the fastboot and u can navigate out of that to bootloader to recovery.
Sent from my HTC Desire using XDA Free mobile app

Completely power down the phone
Then use 'back + power' buttons will take you straight to fastboot
Then flash 4EXT recovery using fastboot commands, backup and partition you sd card, full wipe flash ROM
You can still navigate within fastboot and bootloader using only the volume up button if you need to

Have you enabled usb debugging?
try "adb devices". if it says "unauthorized" and you are don't to get a confirmation request on the phone then use the hardware button combination.
hold vol up + vol down + power, release the power key after the screen lights up but keep holding the two volume keys until the fastboot screen shows.

Were you able to boot in fastboot?
Do you have the proper drivers installed?
