Thought I'd post this in case someone is having a Fastboot problem, i.e., your phone is being an arse and is only booting to Fastboot and your battery has finally lost its charge.
What helps me is to hold both the volume up+down THEN plug in the phone. You might have to press the power button, though, but it should bring up the Boot Mode Selection Menu where you can select Normal Powerup (If it isn't selected already, select it then hit volume up). This should power up and the battery icon will show that it's charging. Let it charge up and you'll have some more extra time to troubleshoot your problem.
By the way, I'm still having the Fastboot problem myself so if anyone could help me out that would be fantastic.

Hi, I'm facing a strange problem with my 2 years old Galaxy Note. It auto turns on as if power on switch is pressed as soon as you insert the battery. Also, if I only press the home button and volume down key together I go into download mode without even pressing power on button, similar thing when I try to enter recovery mode (I just need to press volume up + home button, without power on). So I may think of a stuck poweron button, but phone doesn't cycle in rebooting itself as it should if I pressed continuously its poweron button. Could it be the battery? Sometimes I have problems charging it... the phone stays in charge 3 seconds yes and 3 second no even if I take out the usb power cable (the icon blinks with the little thunder every 3 seconds). If I plug back and forth the usb power cable for 3 seconds twice the problem disappears... what can you say about it? Tried full recovery with stock 4.1.2 rom without success
This may or may not be a power button problem. I had this problem myself! Try removing your battery, cleaning carefully your micro usb port with a thin toothpick and try gently moving it up or down but really carefully!!!, insert your battery and try again. I had problems 2 3 days after cleaning it, but after that no more problems. Also see if your battery has a little bulge. If yes, then you should replace that too.
Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?
Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,
Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?
Try opening and disconnect battery for a bit.
I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?
Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?
Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.
I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:
Did You enter medfield mode using combination with camera button??
By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.
Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.
Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?
Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.
Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.

A panacea for your device.
For those coming to this post in search of an answer to their seemingly dead device.
After looking at Sony's support website, the answer I found was to hold the OFF button inside of the Micro-SD/SIM cover for a total of 2 minutes (120 seconds).
This is tricky for some users, due to the length of time involved.
It is important that the OFF button remain held for the full duration of time.
After this, your device 'should' power on normally by holding the power button.
This worked for me, and I hope it will work for you!
Thumbs up and stuff if this helps~!
I've had my Droid 4 completely lose battery on one or two occasions where I wasn't paying attention to it while doing something else.
It turns out that I have to plug it in and wait until the battery is at 100% to get it to start up again. What is the way around this? Just holding the power button turns the phone on, shows the motorola boot logo, and then shows the battery at whatever percentage it's currently charged to. How do I bypass this and start into the ROM and then just charge from there?
In an emergency when I'm waiting for a call or something, this is something I need to be able to do.

The power button on my phone is completely non-functional, so I have to plug it into a charger to "kick-start" it on the rare occasion that it's completely shut off; which, more often than not, is when my now rapidly-aging battery craps out and I don't catch it in time. So I face this every now and then.
The solution:
Let the phone charge enough to safely boot; 10% oughtta do it. It seems that the phone does charge whenever power is being supplied regardless of its state, but the amount of drain while booting means your charger by itself probably won't keep up
Unplug the phone; this should make it shut off
While holding Vol+ and Vol-, plug the phone back in (you may be able to use the power button instead of plugging in, but I wouldn't know). This will bring up the menu of which the name escapes me at the moment
Unplug the phone (may or may not actually be necessary for success, but I always do)
Select Recovery (Vol- navigates, Vol+ selects); this will get you into the 96% useless stock recovery
Press Vol+ and Vol- together until the menu comes up; this might take several tries because either the phone is fidgety or the timing is stupid-precise
Select Reboot (either Enter or Ok on the keyboard to select, I forget)
The phone should reboot properly, skipping the forced charging thing. You can (and should) plug the charger back in anytime after you hit Safestrap/the post-SS kexec buzz if you have the custom SS installed which disables the popup at boot.

Yes... this is the method I remember using once, but I couldn't get passed the useless stock recovery this time around so I thought maybe I was just dreaming. I guess my timing was just bad this go around.
Thanks again, Septfox!
My DROID 4 is like my DROID 3. When the battery completely dies, you cannot press the power button while it's plugged in.
So, Dead phone. Plug it into the charger. Wait a couple minutes, so it gets some charge. Unplug the charger, Hit the POWER button, then plug it back in.
It won't work if it's plugged in, dead, and charging. You gotta unplug it to turn it on, then plug it back in to continue charging.
That is happening not only with this model phone. On other brands is the same.
Poco M3 Pro 5g
Stock rom
Locked bootloader
It was powered off for some time because I had to replace broken display
Now when I try to boot a battery icon appears and then it turns off. Same thing happen when I plug in the charger
I repair smartphones professionally so I am sure no hardware damage during the repair

I went through it. try holding the power button, connect the cable and only release after the battery shows 1%. you can try holding the power and volume + or power and volume - buttons too instead of Power button only, in the same way. alternatively, you can leave it on the charger for hours and it might turn on. Make sure you are using the supplied xiaomi charger
If I plug the cable or I plug and hold the power button the phone just tries to boot continuously showing the battery icon and then turning off and repeat, nothing really happens
Is that what is supposed to happen?

Yes, It happens. Luckily the phone will reach 1% and charge normally, keep trying
You actually saved me, it worked in the end, after some loops it booted alone, all I had to do was just let it sit there, didn't even have to keep power button all the time, once it started the loop I just left it there and when I came back it was booted.
