Fastboot

I am 99.99999% sure i know the answer to this question, but i figure ill ask anyways....
Is there a way to get into fastboot without the power button?
Recently my power button crapped out on me. I got a new replacement phone, but i wanted to pull files off my old phone...
any help would be appreciated, thanks!
EDIT:
Again, 99.99% sure i know this answer too... but is there a way to sent a power up signal via USB when the phone is off?

does your phone turn on?
if so and you have adb setup, you can use: adb reboot bootloader

Nope, doesnt turn on... When im plugged in via USB either to a computer or a power outlet, i get the battery charging icon, but thats it...
before it broke, the power button was working spotty... then the next morning it was not working at all

I have no idea if this works but worth a shot...
cohrs said:
take the battery out and plug into usb (connected to computer). put the battery back in and when you see the battery charging on the screen remove the battery again. On mine the battery image starts flickering. at that point i put the battery back in and it rebooted.
This has worked for me a few times. Once rebooted you will be able to see your device using adb and then fastboot.
i got the idea from this post but found the timing i used worked better than his random attempts while holding the x key on the nexus one.

If you're really desperate for the data, you could always open the phone up and manually trigger the button as someone above has posted. There probably is another way via hardware tools e.g. JTAG or something OMAP/flash related but I'm not aware of anything specific.

Arc won't boot

Hello guys,
I hope you can help. I'm having issues with my Arc running cyanogenmod 7 (.2 I think). I've been using cm on the device for over a year and one morning it would not turn on. I thought it's out of battery so I charged it. Later I tried to turn it on but it still wouldn't start. I further noticed that when plugged in to charge the LED was not illuminated. I tried a different battery from another arc device, but didn't change anything. (Mine worked on the other device.)
A week later or so, I tried to charge it again and suddenly the LED lit up and I was able to turn it on. Unfortunately, this was only temporarily. I checked the phone later and it was off again.
So I thought, I try to send it back to Amazon where I bought it, and maybe they don't get that I modified the software. But they did...
Any thoughts on what I could do?
Cheers,
Diophantus

Can you get the phone into flash mode or fast boot mode or have it detected by any computer?
Sent from my Xperia Arc S using xda premium

I tried flasboot (0.9 linux) and it did not work. I'll try to get a windows machine and test fast boot

Fastboot doesn't work either. Nothing pops up when connecting the device while holding the fastboot key.

Any other suggestions?

So the LED won't turn blue if you hold the menubutton and connect the USB?
And no green LED on flashmode?
Did you do something special with the phone before it happened?

Nope, it just happened over night. Didn't flash or anything. I had been using the Wifi a lot more than usual, but nothing else.
It is strange, that it turned on that one time.

Can they ask Sony if I unlocked the bootloader or how could they know this?

was an odd thing phone was ringing and shut off, had several calls from same number i had rejected and when i called the number from a landline said the number was not active

i do appreciate the help though was seeing if there was something i hadn't thought of trying already

Similar thing happened to the display model at a local Verizon store. They said after hooking it up it shut off and wouldn't power on, all you get is the battery charge logo and the Orange light. Went in planning to buy one...decided to wait a bit...

Take out your battery AND remove it from a charger. Put the battery back in, then turn it on. If it's connected to a power source sometimes the phone will not turn on.
Do you have TWRP installed? Are you rooted?

5x Wll Not Boot

Hey All -
I awoke to find my 5x off.
Naturally, I though the battery was completely dead.
I charged it for a few hours and still could not get the phone to turn on.
I know the charge is fine because my wfe's 5x charges it no problem.
When connected to my Windows 10 box, Windows reports that it is an unrecognized USB device.
ADB does not find it.
It did boot to Fastboot ONCE, but I have not been able to do that again.
Any suggestions, or is this hard-bricked?
Thanks!

I called Google and they will be replacing the device.
However, I am concerned that I cannot wipe the phone.
Should I be concerned? Or is the data not retrievable?

You can't get into recovery mode?

No, the phone does nothing at all.
It does not turn on and a computer does not recognize it over USB.

You said you charged it for a few hours so does the screen with the white battery still show up or you had just left it plugged it hoping it's charging?

I saw the charging icon on the screen briefly once.
When I saw that, I left it alone, assuming that it was charging.
About two hours later, i tried to turn it on and it did not turn on.
So I tried to boot into fastboot. It did so.
Then, I selected to just start it up. It merely turned back off when I did that.
I booted it into fastboot once more and selected recovery.
It has not done anything since.

When my bootlooping 5X wouldn't let me do a factory reset via recovery mode, I let it cool and waited maybe 15 minutes. After that I was able to get in and cleared it up.

Mine is stone cold.
I am unsure if it is even charging.
The port is clean, so that is not the issue.
