Non-newb: need to boot into recovery without volume keys - Android Software/Hacking General [Developers Only]

Hi guys,
My Galaxy Nexus has volume keys that aren't working. I unrooted it, but now it's in a bootloop. Obviously I need those volume keys to boot into the bootloader. Does anyone know of a way I can get to the bootloader without those keys? Keep in mind that it's boot looped, so I can't do anything on the phone itself.
Thanks,
Alec

If you can take the back cover off, you could probably get at the actual switches with a paperclip or your finger.

[Q] how do i get into bootloader mode?

I just got the google nexus s 4g phone and im trying to root it but i cant get into bootloader mode? Ive tried both volume up and power and volume down and power and it just boots to main screen. Is there something i have to do first to get into bootloader mode that i missed or something?
Nop, just press volume up, and while keeping it pressed hit power.
To add to that, make sure you keep them held down because even letting off slightly early just brings up the Google screen. At least in my case.
Not to mention the phone needs to previously be off
Since you're going to be unlocking it you're going to be using fastboot once you get there. Boot the phone up normally and make sure usb debugging is on if it isnt. adb reboot bootloader

To get into bootloader hold vol- while holding the power button. Don't let go until it reboots. It will now be in bootloader

You need to let go of power, but keep holding vol down. If you don't let go of power, nothing will happen (except the phone shutting off).
The most surefire way (works in just about any situation) is to hold power and volume down. Don't let go of volume down until I say so later. The capacitive buttons will flash after about 5 seconds. Then the buttons will stop flashing, the screen will turn off (if it was on). After that, release the power button, but keep holding volume down until the white bootloader screen shows up.
If the screen turns on at all, the phone will always be able to go to bootloader. Failure to get into bootloader is almost always a matter of the user not performing the button sequence properly, rather than an issue with the phone.

[Q] Boot Lopp + No Power Button

Hey guys, I just got the older HTC One S (C2) from my sister , to play a bit around.
I rooted, unlocked without any Problem, but after flashing it just stuck in a bootloop . And I can't even escape.
Unfortunately the power button is broken and i can barely turn it on by making contact with a pin needle (works rather badly)
ADB won't find my device, and even pressing all buttons the same time won't change a thing.
Anybody got an idea or some other plan?

Beg your sister for not doing to you what you did to her phone...
Your phone will power of by pressing "Power" for 10-15seconds. Is the button itself GONE? How? Once powered of press or in your case "jumper" the "power button + Vol down" at the same time. You can release power when display turns on and just keeping "Vol down" pressed will bring you into bootloader.
You will have to try getting to fastboot. Or pay 40€ for a bootloader repair. There is no other way :/ for
As you did not tell anything about S-OFF you're probably S-ON. So you may be forgot to flash the kernel???
If flashing means you flashed a custom rom. Bootloader is working in every case.
May you post some more infos?
-Firmware / HBoot
-Recovery version
-rom/KERNEL installed
-any other modifications?
Did you face any issiues while flashing?

[Q] Phone boots to recovery only. HELP!

Hi,
My Oneplus One boots only to the CWM recovery. I noticed that my volume down button not working. So I restarted the phone, and now it only boots to CWM only.
In the recovery, the volume down button still doesn't work. It looks like the button may be stuck? and my guess is it's initiating the volume button down + power button to boot to CWM.
But I also tested the Button Test function in CWM, and the down button doesn't even register.
Is there any way to bypass this? I don't need the volume button down to work necessarily, but I need my phone to work.
I'd appreciate if there's any other way to bypass this, or maybe modify CWM file to change the recovery button combo.
If the button is stuck, then no amount of altering CWM is going to help because you'll never be able to boot into the OS with a stuck volume button. You're going to need to physically inspect and fix that volume button. In the meantime in order to have a functional recovery, ditch CWM and flash TWRP, the UI is all touchscreen so no replying on buttons, and it's leaps and bounds better than CWM anyway.

Hey, Thanks for the reply.
I noticed a few more things, which makes me to believe that this is not a physical button problem.
First, whenever I charge the device, the device won't stay OFF. It constantly turns on automatically.
However, if I don't charge, the device will stay OFF.
Second, I can't even go to Bootloader. I tried "adb reboot bootloader" from the command prompt and the phone boots directly to CWM recovery.
Third, if the volume down button is stuck, wouldn't it be activated all the times? So when I'm in CWM, it'll constantly go down, and when I test on Button Test, it should register constantly.
But that's not happening. It's simply dead.
I'm going to try the RMA process, but meanwhile, I would be glad if someone has better idea with the new info I provided here.
Thanks
Im having the same issue did u get it fixed? plz help
