I have no idea why, but the phone won't boot after I initiated a factory reset while on OB2. Only thing the phone responds to is when I press Power + Vol DOWN for 10 seconds. It vibrates, the Android logo comes on and then the screen seemingly turns off again.
Tried getting into recovery but phone does not seem to respond to Power + Vol UP. It did once, but did not go into recovery or fastboot after letting go when the Android logo came on.
Any suggestions?
MSM saved my bacon. Thank you XDA!

So I did a factory reset, the tab rebooted to wipe the device, went to nvidia logo then screen went black, shuts off automatically and I can turn back on just for it to get right past the logo and shut off again, I've tried volume up with power and volume down and same thing happens. Sometimes the power won't even turn it back on for 5-10 minutes. Any suggestions?

Dumb question, but are you sure the battery is charged? I would leave it plugged in for awhile and try again. Then if it still is not booting try to enter download mode while connected to PC. Mine did something similar to this once when I did a factory reset as well. It only recovered after connecting USB to my PC.
I'm guessing you have custom recovery installed?
1. Download the factory image from NVIDIA website (specific to your device version),
2. Go into fastboot by pressing volume down and give a slight nudge to the power button (don't press until the logo comes up, just a quick nudge will do)
3. Unlock your bootloader using the instruction which can be found on this forum (if you have, skip this step) sorry I'm on mobile phone, so a bit hard to do a search for the link with small screen.
4. Unzip the recovery image zip file.
4. While still in fastboot, flash the recovery images using flash-all.bat contained in the unzipped folder.
You will lose your custom recovery and your root, but since you were gonna wipe your device anyway.. let me know if you're stuck somewhere.
I think i might have found fix....
Shut down the device with long press (8sec) Power button
Press and hold Vol down key
Press and release Power key
Device enters fastboot mode
Select Recovery mode option (using Vol up/down for navigation and power key to select)
Device enters recovery mode (after showing NVIDIA boot logo) with Android Robot screen.
Press and release Vol UP + Power button simultaneously
Then select wipe data/factory reset with Vol up/down key to navigate and power key to select
try this but be PATIENT AND wait for it to say erasing then i think ill be normal once its done also just wait with it on the "blank screen" we could have just got ahed of are selves and whent to conclusions and thought it was bricked
Just took the Lollipop OTA update from stock 4.4.2. Upon completion my phone rebooted and is stuck on the LG boot logo. I tried entering download mode (holding volume up button and plugging phone into computer) but my phone doesn't enter it. Attempting to power off the phone doesn't work either, since the phone just powers off for a second and turns back on to the boot logo. I tried factory reset (power + volume down) and after proceeding with the reset the phone is still stuck on boot logo. What should I do?

You can power off if you hold power button longer. wait till logo appears, and still hold, till it gone away second time, and hold even a little longer.
Turns off but still stuck at logo when turned on

I have the same problem with the friend who posted first. There is no way on how to get to fastboot mode and when turned on it just restarts and back to logo. Hard reset is the only thing it allows me to try but no result. Any possible way to get to fastboot or download mode??? Help somebdyy

After i flashed the Lollipop firmware, it looked like the phone got stuck with LG logo but i gave it good 5 to 6 minutes and all was fine. The phone just needed to breathe a little.
I accidentally froze, by my mistake, all my apps with titanium backup, now my Phone is re booting itself after the message "optimizing x app of x"
I'm not able to reboot in recovery neither safe mode but only in fastboot but I'd like to avoid flash stock and restart from scratch, suggestions?
Even to save /sdcard
Thanks in advance

Why?
Shutdown phone from any screen by holding power button for 10 sec (or it turns off). You can do it also while it is optimising apps, does not matter now.
Then hold Vol down+ Power to boot into recovery.
What he said. There's no reason you shouldn't be able to shut it off by holding the power button and then boot into recovery. If you are already doing this then it's probably a case of using the button combo incorrectly (lots of people do). You need to hold volume down, then power (so you're holding them together), then when the phone begins to boot and you see the OnePlus boot logo you need to let go of power but keep holding volume down until you reach recovery. If you keep holding power after seeing the boot logo the phone thinks you just want to reboot again.

Thanks guys, maybe due to panic, cause I need phone and was not at home, I did the button combo incorrectly,
Booted in TWRP and wiped /data did the trick, then reinstalled TiBu and restored all apps
Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"
I had my US version OpO 64GB working with CM12 for quite a while, rooted and bootloader unlocked with TWRP (possibly 2.8.6) installed, then some months ago I tried upgrading to CM12.1 through CM updater. This failed miserably - The phone started bootlooping on "Optimizing apps n of N" - as soon as it finished optimizing apps, the phone would reboot and start optimizing again. Booting to safe-mode (Power + VolUpDown) also fails in the same way (though optimizing fewer apps).
I tried rebooting to recovery mode holding Power + VolDown but it just gives a quick buzz (vibration motor) at the "1+" screen and reboots. The same thing happens when I try to boot to fastboot mode with Power + VolUp. So I'm completely stuck. All the guides show being able to boot either to fastboot or recovery (soft-brick) or else the screen being completely black/unresponsive (hard-brick). My phone is neither of these!
I got frustrated enough that I've let it sit on the shelf for the past 6 months, but now I'd like to fix this. All help appreciated.

Did you try clearing the cache and doing a factory reset ?

That's impossible for me to do since I can't get to launcher or recovery.
No acess to recovery?? Then better take it to service center... Atleast can u boot to fastboot mode or adb accesible then use oneplus one toolkits
---------- Post added at 11:34 AM ---------- Previous post was at 11:31 AM ----------
Install oneplus tool kit, while optimising apps it gets dectected by pc, just make it reboot mode & do reset.... Dnt worry this can be fixed, if all these seems messy then take it to service center

while things are loading, have u tried to hold vol up + power for 10 seconds or until the screen turns off and then hold vol down + power button until the oneplus logo?

Yes, just tried it. Same thing as described in my original post. When I hold power+volup the screen goes blank. I switch to power+voldown until the 1+ logo. At that point:
1. If I continue to hold the power+voldown key through the 1+ logo, the screen goes blank briefly, the phone vibrates once and reboots. If I continue to hold the power+voldown key, the vibrate&reboot cycle continues indefinitely
2. If I let go of either the power button, the voldown button, or both at or before the 1+ logo, the phone boots normally and goes to "Android is starting... Optimizing app n of 119). When the optimization finishes, the phone instantly reboots.
It's like the phone recovery is gone or inaccessible. Could this have to do with the phone tampering setting? As I said, I had this phone rooted and bootloader unlocked, working fine with CM12 for some time before trying an in-place upgrade to 12.1. That's when things went south.

Hello
My stock A515F/DS received an OTA about 3 days ago. After it restarted to finish the update, it got stuck in the boot logo. It will reboot on itself from time to time, and I was able to reboot it manually by pressing vol down + power, but I can't get into recovery or donwload mode (by pressing vol up as soon as it reboots). The screen flickers for a moment, but it reboots again. We are under quarantine by federal law so I can't get my phone to samsung. Is there any way you guys know to flash it without going into recovery/download mode? I don't mind losing my data, everything is on my drive account, I just want my phone again
Thanks in advance
I think there is no way without entering in download mode or bootloader. Try with this:
When the phone is on, no matter which state, press Vol down + power until it reboots. As soon as the screen goes black, change to Vol. up+power. If this is successful, you can then select Reboot to bootloader to enter in download mode.
If this doesn't work, the next solution is waiting the end of quarantine
