Nexus doesn't boot - Nexus 5X Q&A, Help & Troubleshooting

I'm using pure nexus rom for a while now and didn't give any kind of problem. Was casually using whatsapp on phone and battery was around 50%, phone suddenly started to vibrate. It vibrated for around 10 secs and it finally got shutdown. Now, It doesn't power on. I can enter into bootloader by holding vol down + power button for several seconds (than what it usually takes), but after entering bootloader, it doesn't go into recovery or start the phone. restart bootloader function is restarting bootloader normally but boot into recovery and power on doesn't work. Google logo appears for few seconds and again powers down. Please help! Thanks in advance!!

Fastboot and flash it? It's encrypted. I don't wanna loose my data. But will consider if nothing else works.

i have same shi* trying to flash recovery via fastboot and see if it loads....

@cbhhargava: if fastboot connects, you can erase both of the caches and fladh PureNexus.zip. Without erasing /data. Fastboot-syntax.

didn't work... tryinf to flash stock image via fastboot...

didn't helped either... used Nexus Root Toolkit to flash stock image - still no change. blackscreen after Google boot screen, i'm starting to think it's hard bricked either soft bricked....

then there's the oven-procedure (it's described here often): if it boots after heating, you can save your data and let replace mainboard.

Same issue

HTC one x bricked need help...

I just flashed a arhd rom a kernel and InfinitySound mod and then my phone was stuck in the htc quietly brilliant screen...
The main thing is i can't even enter the bootloader with "vol+power down" help please...
Keep pressing the power button for more then 5 second and you will see the 3 buttons blinking. After that phone will restart and then press volume down to enter in hboot.
Then look on xda a tool with witch you will flash a stock kernel.
Perhaps this is the solution for you

i tried it, but no luck... it still boots into the htc quietly brilliant screen.
Hold the power button to force a reboot. As soon as your HOX powers off press and hold vol down, keep holding until you enter hboot. It might take a few attempts
First boot can take awial I don't think your stuck its just loading

It's stuck not loading because I have waited 10 hours already. Also, I keep trying to get it into boot loader , but to no avail... tried 30 times already...
Without getting into the bootloader, there's nothing I can do...

Does your phone keeps rebooting?
If so, it sounds like you haven't flashed the correct boot.IMG
You need to flash the correct boot.IMG that is for the kernel you flashed.
-----
As for boot loader, why don't you just use the adb command?
adb reboot bootloader
As for the button combination not working, you need to hold both power & volume down at the 'exact same time', and don't release them until your boot loader screen shows - even if it does an extra reboot, keep them held!

I am having the same problem, and i forgot to backup my previous rom. I rooted, and unlocked my phone, then i tried to install the rom, it installed. however now it just stays in the spinning loading sign for CM10. Is there anyway of putting another rom on the >fake, ie internal> sd card, which cant get removed from the acctual phone? so then i can install that rom? i have tried reinstalling the rom but that didnt work
Click to expand...
Click to collapse
If you have cwm 5.8.4.0 you can mount the sd card as usb drive.
Don't forget to flash the boot.img that goes with the ROM.
fastboot flash boot boot.img
You are probably forgetting to flash boot.img using fastboot from your pc, from your description. After flashing boot.img, issue a
Fastboot erase cache
Or you will most likely get bootloops.

How to reboot Xperia S

Hey, i have installed TWRP recovery. It works, i can get to it and make backup etc. But how I can power on my phone? Really, I have no idea. Normally I should just push Power On button, and it will work. Now it doesn't. Phone is restarting all the time to sony logos, then pink led, then blue and power off. Then after few second phone is restarting again and again. How I can just normally power on my phone?

Please tell all the things you did before the problem begins. What have you did last thing to your device? Put your device on charger until your led turns green.Then flash official firmware by flash tool.
Another thing do you able to boot to twrp recovery?
So i have unlocked bootloader (but like 2 months ago) and installed twrp recovery. Actually now, since the battery decharged, because it was restarting all the time, i can do ****. I can't put it on charger, because its restarting after like 5-10 minutes after charging. I can't flash my phone, because its decharged or its stucked on sony logo. I can't use the official repair tool, because its not recognizing my phone. Now I can't even get to the recovery.

ok calm down.Its not a big problem.Just follow these steps.
1. while you see sony logo or when the phone is turning on ( Press and hold VOLUME UP key+POWER key simultaneously).While you feel a short vibrate release the keys. Now put on charger.hope you will not get the automatic turning on problem.
2. Then Download Flashtool software from internet. ( official repair tool will not work coz you have unlocked your boot loader)
3. Download your mobiles official stock firmwire.Then flash it using flash tool.
You can learn about flashing ftf(firmware files) by flashtool from internet.
Best of luck
Ill try to do that 1 step, but I think it wont work. And I have already googled those next steps. Anyway thanks for those steps
Yep, nothing actually works. I get the sony logo, start pressing power button and volume up, then green led is lighting. Its fine for like 5-10 seconds, then its decharged, need to charge for like 20 seconds, and then again sony logos appear. Infinite loop.

The green light means you are on flash mode.the mode is used to flash firmwires.so you need to install flashtool.then install flash mode drivers.then do the steps to flash firmware.
But I can't install anything, since the xperia just restarts after few seconds or just power off, because I can't charge the battery.

You have to install flashtool and drivers on your PC.search on google guide to use flashtool
I have installed drivers and flashtool, but man. You don't understand me. The phone is not charging when im in flash mode. And I can't charge it, because the screen with sony logo can't be powered off. I can only go to flash mode, but in this mode, phone is not being charged. And if I try to flash firmware the phone just run out of battery.

1. R u able to power off your device by volume and power key?
2.OK you can flash stock kernel by fastboot mode.it can be done with a low battery.(may be you have a corrupt kernel)so after flashing kernel you can try to turn off your device by pressing and holding vol up +power key.don't let go any of these two buttons until you get a vibrate.I have never listen or faced this type of issue where we can turn off our device.
---------- Post added at 07:53 PM ---------- Previous post was at 07:52 PM ----------
You can also try doomlords kernel.it has recovery included.
1. Im not. The only way to power off the phone is just to wait until the phone decharge.
2. How to do this? http://forum.xda-developers.com/showthread.php?t=1729280 If i download this Build 17 (Fastboot). Then what? I need to try to get fastboot somehow?

Best way is to go to a mobile shop and ask him to remove the battery by unscrewing. You can try at home to do that if u have tools to unscrew

Do You still have a working recovery? If yes, then You can push a ROM zip to phone via adb while being in TWRP and then flash it. Also, again if You have working TWRP, You can turn off phone via it by going in TWRP>Reboot>Power Off.
You can also turn off Your phone by pressing Power and Volume Up button together. You will first get a single vibration. Keep the combination pressed, then You will get three vibrations. Now Your phone will be turned off fully. This combination will work.
Whenever You connect Your phone to PC/Charger, Your phone will charge, regardless it's in bootloop or not.
But, can you read? I said i cant get to fastboot, cant power off phone, cant acces twrp.

Phone Not Booting Properly

I have a rooted One M8 here with a custom ROM and recovery that I have been trying to boot into recovery however every time I try the phone seems to crash, turn of and then won't boot. After about 15, 20 minutes the phone boots up again by itself. Anyone else ran into this problem before or any advice on a solution? Thanks.
You can get to bootloader okay?
If so, go into fastbootmode (connected to computer) and fastboot erase cache, and try installing TWRP again.

So what exactly worked, and what didn't? The way you've typed it, I can't tell:
You can boot into bootloader?
You were able to flash recovery?
You are able to get into recovery?
The ROM flashed successfully?
But then it failed to boot?
Also, what ROM?
What version TWRP (version number)?
Try another ROM. Be sure to do the default TWRP wipe (data, cache, Dalvik) before flashing ROM.
I can boot into the bootloader and into the system it's self but it takes maybe 15 to 20 minutes everytime the phone is turned of to start back up again and begin booting.
I'm not sure what version TWRP is as it been months since I flashed it and I can't check because I'm waiting on the phone to boot again.

So do I have this right: The phone turns itself off, will stay off 15-20 min; during which time you can't do anything until it starts to reboot itself?
What happens if you hold power button, or power + vol up for a minute or more? Do either of these force it to start booting, or no response until it boot on its own (15-20 min).

Stuck in Bootloop, reboots every 15 seconds, holding power button does not stop it

The first problem I encountered while rooting my phone was that TWRP wouldn't stick, even though I didn't choose read only (ie i allowed it to make system modifications on the first TWRP boot) after rebooting
and booting back into recovery I would boot into stock recovery, instead of TWRP. So I tried flashing twrp, booting into it and rooting the phone, which was successful!
THE ROOT was successful, TWRP still didn't stick, every time I want to boot into TWRP I have to boot into it via fastboot.
Getting to the main problem, I booted into twrp, flashed a custom rom and got stuck in a bootloop while rebooting. It reboots every 15 seconds, I have kept the power button pressed for almost 2 minutes it doesn't stop the bootloop, I tried other combinations of vol buttons and power buttons does nothing.
One weird thing is that while it's in the loop I just have to press the vol down button and it boots into fastboot (as opposed to both the power button and vol down) when I boot into fastboot it stays there for about 6-7 seconds before rebooting, I tried booting into twrp through fastboot, but before I am able to enter the decryption password to start twrp, the phone reboots.
Should I let it run out of battery? will that stop the bootloop? I have a backup in twrp but I can't access twrp!
Does anyone have a solution?
[update] I let it run out of battery and on charging it continued the bootloop, with great difficulty i managed to install stock img file but the device just wont quit the bootloop

1. Try flashing new recovery image using TWRP booted via fastboot.
2. Does your phone had contact with any fluid or was in place with high humidity level for longer time? Your power button is short circuited. In other words it is in pressed state all the time. I had same problem on my previous P2 when I came from 1h running session in light rain. Some sweat and/or water got inside my volume down button and same thing happened.
In my case the phone button recovered itself after drying and clicking it a lot of times

I can't access TWRP as the phone doesn't give me enough time to enter the password for decryption, which is asked at the start every time you boot into TWRP, I get like 5 seconds in TWRP before the phone reboots
It is possible that the power button is spoilt as I have sweaty hands...

That's the reason. I know that pain. You should try pressing that button with different pressure (but be careful) and move you finger while doing it. Maybe it will recover itself. If not you should find someone trusted who will open the phone and clean the buttons from the inside. It's a shame that Lenovo just left this construction vunerable like that.
After you get your P2 working properly again then just buy case that will cover whole buttons to prevent situations like this next time. Also make sure to clean it regullary inside.

can't boot, stuck at google logo

in the end of summer my tablet sometimes freezed or got slow. after a minute it worked fine again. then sometimes i couldn't acitivate the screen, altough i knew the device was running as i used it minutes or seconds ago. when i restartet it through long pressing the power button it restartet, but stuck at the google logo. after several trys it booted regulary but needed longer to show the apps or widgets on the homescreen. but it worked fine afterwards. this happend to occur more often then. sometimes i couldn't boot (stuck at google logo) for several days or weeks. then worked again for 1-2 days. everytime it stuck, i also tried the boot menu, but also with the other options there it'd stuck at the google logo. finally i can't start the tablet since 2 month. the day before yesterday i contacted google, but they couldn't help and wouldn't replace it, as the warranty ended in january.
is there anything i can do now?

THIS WILL ERASE EVERYTHING. I HOLD NO RESPONSIBILITY FOR ANY LOSS. CONTINUE AT WILL
Try booting into recovery mode by holding POWER + VOLUME DOWN until it boots into a menu and choose recovery mode.
Then an android with an exclamation mark should appear.When he does press POWER BUTTON then while holding it press VOLUME UP.
Recovery options should appear.
Select (update from ADB) and use a pc to sideload your firmware .Which should restore it back to normal.
thx. tried this already, but also the boot to recovery stops at the google logo
