Only turn on in fastboot mode - Nexus 4 Q&A, Help & Troubleshooting

My nexus 4 isn't turning on in any way.
If i connect the power cable a red light blink once and stop, pressing the power button nothing happens. The only way to get some activity it's pressing the volume down + power and connect the power cable, but turn on in the fastboot mode and can get out of there. If i try recovery mode the phone dies, if i try to reboot the phone dies, if try to normal boot the phone dies.
I can turn on in download mode, but the LGNPST don't recognize it.
Fastboot commands via prompt are fine, unless i need to do something that reboot the phone.
Someone can help me?

Recovery Mode to start the Moto X play

and sorry for the English.
After that I decided to upgrade to Android 6.0 marshmallow Always restart the device in recovery mode. Even if I disconnect and reconnect it always falls into the Recovery screen.
I've tried reinstalling Rom Stock and does not normalize.
A note: I can not turn the appliance by pressing the Start button in Recovery Mode. But if I turn off the power he again falls into the recovery mode screen.
When he is off and the battery cable to the connected energy only appears to Recovery Mode screen.
Help me! I do not know what else to do.

Power off completely and try to get into fastboot mode by pressing both Power and Volume down button. If you able to access fastboot then no worries.
Exactly what is happening.
When I turn on the Device normally, rather than direct it into the android system, always falls on the Fastboot.

if reset doesn't matter to you then I suggest you to do a full flash with stock rom, either using fastboot commands or simply use the rsdlite tool

Yes.
You still can go to fastboot by force turn-off.
When the USB logo appears, hold the power button, the phone will power off.
Then, hold the volume key, AND THEN, hold the power key too. When the screen turns on, release power key and keep holding volume up until you see fastboot.
To use your recovery, you must unlock your bootloader.
You can go back to your system by using the REBOOT fastboot option.
I tried but it just show the USB logo and suddently reboot... I made a video, its uploading, I will post here when its done.
Sorry my bad english:

Hard brick of Z5C ... can I save it?

Well, I did it this time.
In a valiant attempt to install a custom ROM, I erased every partition using fastboot,
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
fastboot erase cache
Now what I meant to do here was flash a recovery, using
Code:
//fastboot flash recovery TWRP.img
but repeating this so many times over the last 48 hours, I did not do above and instead went quickly right into below,
Code:
fastboot reboot
The system rebooted as I told it to ... right into a black void of nothing. Now their is no 'recovery' image and no 'bootloader' image ... the phone is hard bricked, won't turn on at all, dead. I was so close to getting to the custom ROM! Is there any chance to get it back into recovery mode? or have I learned a $350 lesson?
Edit: Further research indicates it may be possible to force the system into fastboot using a USB jig. Has anyone tried this method?

When you plug it in while holding volume up what happens?

Nothing. LED flashes red every few seconds. The same response if plugging it in without holding volume up. Along these same lines, holding the power button on for a few seconds causes the small vibration haptic feedback to occur as if it is turning on normally ... but nothing happens the phone remains dead. Similarly, holding volume down and the power key causes a small vibration haptic feedback as it was booting into recovery ... but nothing happens the phone remains dead. I haven't seen anything on the screen appear, or the phone turn on it any way, since executing the fastboot sequence previously described.
Whatever you did, you should still be able to enter in flash mode and flash a stock firmware. And by this I mean full stock firmware, not a ROM.

Ok, that would be great. I would be thrilled to get the stock ROM back, at this point getting the phone to turn on at all would be a victory! Would you please describe precisely how to do enter flash mode with the phone in the current state? To reiterate, the phone will not turn on in any way (normally, or volume down + power to boot into recovery). The only life in the device is a slow blinking red LED when it's plugged in, and a quick vibration after holding the power button. The screen has not turned on in any way, or the LED shown any color other than red, since executing the fastboot sequence previously described.
hold power button + volume up and to force shutdown
and then hold volume up (or down, i don't quite remember) while connecting it to a pc (hold the button while connecting the usb cable).
If the led turns green or blue, congrats
The power key has nothing to do in this context. It is used only to boot into recovery or force OFF.
While holding VOL ↑, plug the USB cable to your PC to enter into fastboot mode (blue light)
While holding VOL ↓, plug the USB cable to your PC to enter into flash mode (green light, or maybe nothing)

Nothing. Device still unresponsive as described.
does your PC detect the device ? (new device sound notification)

No, the PC does not currently detect the device. All drivers are correctly installed as the phone was recognized accurately prior to the described fastboot sequence.
This is weird. I already erased everyting via fastboot too a while ago, and I could still flash it.
Just to be sure.... unplug all other "smart device" before anything (drivers can't handle more than one device at a time when it comes to FB or flash mode). Open the device manager and let it to the foreground. While you hold the vol down key, plug it and keep holding it until the device is detected. Don't expect any reaction on phone's screen, it remains OFF in both fastboot and flash mode. So, if the device manager reacts, you win.

I'm getting something here which is very encouraging! Executing your sequence causes the device manager to blink (refresh) as if it sees something, however no new devices are recognized in the tree. The phone LED goes to a solid green, reminiscent of a fully charged battery, stays on for about 30 seconds, briefly blinks red and then back to green, etc. The device manager is certainly reacting here it just doesn't recognize the device.
So here we are, you win. Because you have the "two", detection and green led. And if this state goes off after a certain time, it is normal. There is a kind of countdown and the device quits that mode if nothing is sent to it. You should be able to flash a firmware now with flashtool software.
Just ensure you have proper drivers installed properly (WinUSB drivers need to turn signature verification OFF before or Windows will block the installation)

Unbelievable! You saved me! I'm back up with the stock ROM and peace of mind to attempt the custom ROM process again. Saved me $350 ... thank you!!
That's great : )
It is almost impossible to hard brick a Xperia. If something goes wrong, remember flashtool ^^

Help! Stuck on black screen and cannot get to fastboot

I tried unrooting my 6T and something went wrong. Now when it boots it shows the bootloader unlocked warning then goes to black screen and stops. It will randomly vibrate when I press the screen or the power button. My computer doesn't recognize it and I can't even seem to be able to turn it off completely. The only thing I can get it to do is reboot by pressing and holding the power and volume up buttons.
Any advice on how I can force it into fastboot or get my computer to recognize it so I can working on it?

Keep pressing simultaneously volume up , volume down and power button all three of them until you get the fastboot screen.
It maybe takes a while...

like the first answer:
hold vol up, vol down and power butten as long as the phone boots into fastboot mode and flash fastboot Rom OR
hold vol up and vol down for about 5-6 seconds, and plug your phone to your computer. if it gets recognized (with typical sound of windows) try msm tool. And be sure you have the qualcomm driver installed.

Galaxy A40 infinite loop - impossible to turn on

Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!
The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...
you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.
