try to connect you phoen to your computer to check if it is still on?

I think I have encountered that error before too, was using the latest nightly 54. Even if you press the power button nothing happens..
I held down the power button for maybe like 20-30 secs or so and then it would restart again, but then I'd get a bootloop and to fix that bootloop I had to restore an old nandroid

Omg thank you so much! I did as you said and it restarted (without loop)

No problem! I wonder why mine goes into a bootloop, but whatever. Glad it worked for you though!

Power it off fully by taking out the battery and wait for a few minutes. Then press Vol- and then power button, till ! mark comes. Then press both Vol+ and vol-.

thanks, left it for a good few minutes, all i get is a few minutes of black screen, followed by the red motorola logo, still nothing,
the weird thing is that it bricked itself after running fine for the last few weeks.

Hmmm, that worked for me. Took out the battery, left it for 2 minutes. I put back the battery, nothing happened. Then I realized that the phone had gone off so I did what I told you.
I can get to the bootloader with no problem, stock recovery on the other hand is completely absesnt

You're not doing it correctly I suspect. However, flash an sbf and try.
By not doing it right, what do you mean?? this is what ive been doing take out battery - wait - replace battery and then hold power button down then hold the power button while keeping the volume down key pressed
RSD lite is showing the device as Omap3630 and imei as N/A

What I mean is that when you put the battery back, the phone should not switch on (the moto symbol should not come)
As long as it shows in RSDlite, its all good.

THE BLUE LED ONLY COMES WHEN CUSTOM RECOVERY IS INSTALLED.
SEE GOOGLE ON HOW TO ENTER STOCK RECOVERY. IF YOU MANAGED TO USE RSDLITE THEN I'M SURE YOU CAN GO TO STICK RECOVERY.
When you put back the battery, does the phone start? If it does then remove it and wait a little longer and try. It should work, it has worked for me. Plus If it shows in rsdlite you can try flashing to stock.

Be sure to turn of the phone completly by holding the power button untill it starts to reboot. You will see the lg logo for a short while. After that do the volume down + power button. When you see the lg logo let go and press (and hold) volume down and power button again. Now you should be prompt to press the power button three times to reset the phone. This will take you to the recovery and let you restor your backup if you have made one.
Hope this will help you.
I ran into this same problem not too long ago. The best way to get your phone back working is trying to get into download mode and reflashing pure stock.
Just hold down the power button, even when it tries to boot up. Keep holding after the second vibration where it tries to boot up again. Then, if the screen stays black, your phone is fully off.
Then follow the instructions on here http://forum.xda-developers.com/showthread.php?t=2432476
I had the exact problem and I installed LGMobile Support Tool. It will flash stock recovery + stock system. Once the program complete you'll need to hold the volume down + power button. When you see the lg logo let go and press (and hold) volume down and power button again. Now you should be prompt to press the power button three times to reset the phone. Then will start up CWM recovery and will return you to stock.

Hmm i did the button procedure, and took me to twrp i installed recovery but now it says i only have 11gb of internal storage, compared to 19 i had before. I saw that people who used the lg launcher to install recovery to their phone in download mode had the same issue. Have you expereinced this? Does it really mean i only have 11gb? Mine was the 32gb version

Most likely your phone has the D80010o firmware, downgrade to D80010d and you shouldn't have that issue you've described in the OP.
When downgrading, follow the instructions from this thread: http://forum.xda-developers.com/showthread.php?t=2432476

Possible soft brick or hardware failure?

I think my Z1 is really dead.
The phone is stuck on logo screen and gets very hot. The battery fails from full in less than 1 hour. No button combinations will work for reboots to recovery or fastboot and I cannot switch it off (Just reboots to logo screen every time)
I can ADB to the phone but not fastboot. If I adb reboot recovery I get a messed up corrupted screen with green vertical lines and flashing colours. Same for adb reboot bootloader (but only green vertical lines)
I searched around but no-one has this exact problem. I have tried QFIL but I can't get a port as adb reboot edl looks like it goes to the same corrupted screen and nothing happens
So is the phone dead or do you have any suggestions? Any help appreciated
Bro i recommend you to try pressing power button and both volume buttons at a time so you could go to recovery mode.If u try normal recovery process buttons at this time won't work.

Ok first thing try pressing both volume buttons and power button for 10 sec at a time. And as soon as the phone restarts leave the power button and press both the volume buttons after the vibration to go to recovery. If that doesnt work then use adb commands to restart it.

Finally had some time to look at this and amazingly that works (holding the 3 buttons). I thought I had tried every button combination going. Rebooting by adb didn't work either before. So thanks

HTC U Ultra stuck in reboot. HELP!!!

Hey guys,
So here it goes. Phone was getting really slow, so I did a factory reset on it. Worked pretty fine for a few days and then suddenly yesterday phone started freezing while starting. Just get to see the HTC Logo but thats it. I have not unlocked the bootloader since I never felt the need to root my phone.
I have absolutely ZERO experience in rooting a phone or flashing the ROM. Please provide me a dummy's guide to fix the darn thing and get it running back up.
P.S:- I have the 4GB/64GB version

hi,
press and hold volume down + power key until the phone start into fastboot mode
then chose with volume up/down the "reboot to bootloader" press power button, then a white screen with colorfull font appers
then chose "boot recovery mode" in the same way as before and press power button, then a screen with a red exclamtion mark appears,
now press and hold power button + press volume up key several times, a screen appers,
now chose "WIPE DATA/FACTORY RESET" and press power key,
after this has finished maybe there is a reboot option, chose it and press power button
this should bring your phone back to life
if not, or your phone makes noise or huanging, press and hold volume down + power key until the phone goes into fastboot there you can power down
if your phone does not boot normal then your phone need to send into service...

Redmi Note 7 stuck on bootloop, can't even hard reset it

Hello.
I have bought my note 7 in July of this year. Everything was working fine until today. Out of nowhere, my phone restarted and got stuck on a bootloop. It doesn't go past the redmi logo screen, keeps restarting after that. I can't even hard reset it, when entering in recovery mode, it doesn't stay there, instead it restarts again and again. I tried formatting it on my computer, but the PC won't recognize my phone.
I'm out of ideas, I can't seem to find anyone online with the same problem as I do.

Well, somehow the phone let me format it. I guess the problem was with the power button, coming to think of it, a few days ago it appeared randomly on the screen the options to turn off the phone, reboot, etc. Maybe the button got stuck somehow, I have no idea. I managed to press the format button and it's back to normal, as of now.
Solved without format!
the same happened to me with Redmi Note 7. I followed the instructions from the link posted. After pressing Volume Down btn + Power for more than 15 seconds for a couple of times it got unstuck. Try that!

Issue also happened to me.
Get to the recovery mode, and try as many times as it takes to select the Reboot option. IF and WHEN you select it, thos should take you to the new menu saying Rebot or Go back to Main Menu. Select Reboot. That did it for me.
Before that it was rebooting for 2 hours and the trick with the power button and volume down (fastboot mode) did not work...
My redmi 7 got stuck fo second day now, keep rebooting, when I press power + volume up, sometimes reset menu appears but fast disappear. Sometimes it stays for a while but half way through resetting it boots again. Sometimes it begin to allegedly wipe data but stops half way and reboot again. It's wife's phone and she's not deleting stuff when phone is full, I think that's the reason, we'll see...
