Battery pulls | bootloops | black screen of death? - Nexus 6 Q&A, Help & Troubleshooting

I have never owned a nexus device. But I am always flashing new ROMs on my note 2.
When things go south (bootloops, black screen of death) I can pull the battery from the device, boot into recovery and move on.
What is the solution to these type of issues for devices with sealed batteries?
Thanks!

You hold the power button for about 15 second and your device reboots

I think you hold Vol - and Power

This combo would take you either to fastboot mode or recovery. Not the exact battery pull outcome that the OP is asking

My bad. Haven't had a rooted Nexus in over a year

On the Nexus 7 (2013) (should probably be the same for the Nexus 6), all button combos you need to know are as follows:
- Power & Volume Down (while off) takes you to fastboot.
- Power & Volume Up (while off) takes you to recovery.
- Hold down power for a while (On/partially on/frozen/wherever) forces a shut down.

Nexus 7 stuck on splash screen

Not a big deal, I know what the problem is but with no battery to pull how can I shut off my N7 or restart it again? Really don't feel like waiting for the battery to die.
I believe holding power and vol down for ~10 secs is the equivalent of removing the battery.
Have you tried just holding down the power button for 10 secs or so? If I recall correctly that is the equivalent of doing a hard shut down to your device.

OMG thank you guys!!!! i got so scared
won't boot past splash screen
I have rebooted the tablet 10+ times with vol + and vol - and it is still stuck on the Google screen when it starts up. In fact I can't make it turn off, only reboot and go right back to the Google text screen. Any ideas?

nexus 7 Safe Mode

So a trick (I actually found out on accident, and I am not sure it is fully publicized or if it is fully used) is booting the device into safe mode.
When you are in the device, hold the power button down as if you are wanting to power the device off. Now, instead of tapping the Power Off button, hold it down and it will prompt you to reboot into safe mode.
Again, sorry if this is old news, but this is the first time I have seen this.

Accidently entered Sideload in CWM..

Hi!
I accidently pressed "apply .zip from sideload" in Clockwork Recovery, and now I'm stuck on a screen saying:
Sideload started...
Now send the package you want to apply
to the device with "adb sideload <filename>"..
.
How do I exit this/reboot? I've pressed the power button for about 2 min, and nothing happens..
EDIT: I really need help now! The phones battery ran out when in this Sideload mode, now when I try to charge it, it's only an orange LED turned on, and I can't turn the phone on! It doesn't vibe and the screen's just black!
EDIT2: The phone's on now, I just had one of those panics..
If you ever get in it again by mistake, and you have a rom .zip you could flash, flashing that will work the same as if you had selected flash zip from sd card. Rather than get the .zip from the sdcard though, it will get the zip file from your pc via usb.
I have no idea why we can't cancel or hard reset/power off in this mode.
check my thread here for what happened to me http://forum.xda-developers.com/showthread.php?t=2200359&highlight=sideload&page=2
It seems left over drivers from my galaxy s 2 were causing me issues on my first 2 computers, but the 3rd computer was completely fresh with no previous driver installations and worked a charm to flash the zip.

huh i have xperia neo, xperia t, xperia x2, sammy s2 (miss's ex-phone) and friends nokia c-something and ofc xperia z installed here and i have no problems with drivers
I'd never had any issues either, that includes rooting, flashing CWM, bootloader unlocking and using flashtool with it. For some reason it didn't like like fastboot mode (threw back errors for any commands typed, the device was recognized, but not useable, it wasn't showing as [sideload] like it was once on the fresh pc)
Accidentally did that before also.
to get out of this mode. press the power button and Vol+ button until you get a vibrate confirmation and the phone screen blanks. keep pressing on the button combination until you get 3 vibrate confirms that would hard shutdown the phone. press the power button until the phone give a vibrate indicating its powering on.

You sure it was on the XZ when it happened to you? No button combination for any length of time works. I tried power, vol up, vol down, power + vol up, power + vol down, vol up + vol down. All for 10 sec, 15 sec, 1min +. Nothing.
I've been there too some time ago and after short period of panic and holding power for various length of time, I eventually pressed power + vol up (can't remember how long but not long for sure) which did the trick.
power + vol-up is the RPM cpu signal to reset the SoC and if you continue to hold it power off. however, there is something else you can do too, the mini adb that runs for sideload understands adb reboot.

On razr i, press power + vol-DOWN till the cel reboot... and its down
Anyone who gets here with the HTC One: power + voldown under a bright light (light sensor). I spent an evening trying every possible combination (this was the closest thread to the subject) until I read the 'under a bright light' thing elsewhere which did the trick.
it's work for me (currently using SG SIII mini) with (power) + (volume+).. it let me back to CWM "homepage" (the main page)..

Help please Aroma is stuck and holding down power won't reboot the phone

I HATE Aroma installer. didn't touch the screen and install is hung.
holding down the power button until the capacative keys flash does nothing.
Any other key combo to force a reboot?
EDIT:
adb reboot does nothing either device not found
Power + VOL down for about 10 seconds.

Not holding it long enough then. That's "battery pull" button combination. It can literally take 10-20 seconds. The buttons flashing is a good sign.
EDIT: Timed it on my phone, exactly 15seconds.

Huh, it's always worked without fail for me.
Congrats then, you get to wait until your battery dies.
try just holding power until screen goes off then volume down until in bootloader. may take a while but it works ive been in far worse situations with this phone but it always comes back. starting to think this phone is really hard to brick. all in one toolkit is a lifesaver if your not using it you should be. if you have a problem getting into recovery use it and if recovery starts then reboots or closes back to bootloader erase cache with all in one toolkit the boot to recovery
Define a while. Ive held the button down while lights flashed 200 times. It won't turn off.

where are you stuck at? download all in one toolkit and see if that has something that will help you. it saved me a bunch of times already. if the phone turns on or is on your okay. its just frustrating sometimes when you think you might have ruined a $600 device but as long as its on your ok no need to stress

just hold power+ volume down if it doesnt reboot after a minute let go and try again. or you could try all in one toolkit for your carrier to reboot to bootloader. trust me ive been stuck in aroma countless times there is a way
As I've said, adb and fast boot don't see the phone. I'm just going to have to wait for it to die.

If you've held the buttons for around 40 seconds you are going to just have to wait for the battery to die happened to another person. One other thing count the flashes after 20 release and then hold again and it should reset at 15 flashes if not then you are going to have to wait for the battery to die. Good news is after that the other person was able to get back to recovery and didn't have the problem again.
still nothing. Hope it drains down completely over night. I need to be able to get the thing up and running tomorrow
As an Evo owner I was shocked to hear the correct procedure for that phone was pwr + VOL UP AND VOL DOWN yes all three at the same time. I assumed vol up and vol down could not both be selected at the same time because they were on a rocker switch where, if one side is low, the other must be high. But it turns out you could do both. Is the HTC One like this?

back up and running. battery finally died. Flashed stock boot.img after a recharge and all is well.
I'm swearing off of aroma installers from here on out.
Had the same problem also today. But I did not give up to try pressing power + vol down. After several attempts the phone finally restarted.
You're more patient than me I guess. I worked at it for more than an hour and a half.

Is my note 9 bricked?

Hello everybody,
First of all, please forgive my time to time poor english. I tried to fill in my presentation and hope it's ok.
I also want to thanks all the developpers that make a great job to optimise and/or improve stock roms and to help people like me that are not so good in developping.
Let me explain my problem :
I've just bought the Samsung note 9 SM-N960F/DS I was dreaming of.
when I put my sim card inside (a french one) he went on a firmware update, and my phone changed for a french CSC (XEF). Thus, I losed some functions I like, such as SpO2 measure in Samsung Health (I know, it's not so important but...). I couldn't also force the sound in earplugs when phone whas ringing, even by using "Soundabout apk" that was working with my note 4....
I don't know why Samsung changes the available functions regarding the country as we pay the same price for in fact a bunch of functions !!!
I tried to come back to the initial CSC, by flashing an official rom, and following a tutorial on XDA site explaining how to do without rooting, using combination files.
But I certainly made an error as my phone has restarted in a curious mode named "kernel panic upload mode" that I cannot escape. It's impossible to go back to download mode, even with combo like vol down + start button, or other combinations of buttons.
This phone wasn't rooted and i'm afraid now as I don't know how to flash a working rom on it. Whem I use Odin, the flashin fails at beginnig (at setup connection step).
Does somebody have an idea or a solution to fix this phone?
I join some picture of the current state.
Thanks for your answers

Hello Enzyne,
Thanks for your help !
I tried Vol up + Bixby + start, vol down + bixby + start, vol up + start, vol down + start, vol up + vol down + start, but nothing works.
I can't go back to recovery mode nor to download mode...
Odin says "added" but can't setup connection...
Have you flashed with this PC before using Odin? Can you possibly try another PC? Maybe different USB cables just to eliminate possibilities.

I used stock cable, given with the phone.
I gonna try with another one, and on anotehr PC... Maybe will I be lucky... But i'm not optimitic...
It could be that the drivers are no good. It is also possible that you may need a warranty exchange. I'm not aware of any other boot-loader level recovery process besides odin. Maybe even try another version of odin that is known to work with our note 9.

The Kernel Panic Upload Mode doesn't prevent the phone from booting to Recovery.
1. Make sure your phone is completely powered off.
2. Press and hold the Bixby button and the Volume up button.
3. Press and hold the Power button. At this point you should be holding down three buttons. Don't let these go until you see the Recovery screen pop up.
That's really all there is to it. If you have a case that goes over your buttons it's possible you aren't pressing down hard enough for one or more of the buttons to register.

Not to nit-pick,but,when the phone is fully powered down,the simultaneous 3-button push can be released as soon as you see the Note 9 splash screen & the recovery screen should pop-up within a few seconds.
Only reason I mention it is possibly the OP is experiencing issues by holding one or more of the buttons in too long,(just spit-ballin' here on this point)............

Hi Koliosis, and thanks for your help.
In fact, I even cannot power down the phone !!!
The only thing he does except showing kernel panic is to quickly flash on samsung splash screen when I push together vol down and power button, before to go back on panic kernel screen:crying:
No splash screen with bixby + vol up + power buttons combo...
The problem came after a failed flash with combined files (the good ones for my phone, I verified...)
Is there another way to reinitialise the phone except via Odin or Smart switch?

You got me there, I haven't used ODIN since the Note 5 days, LOL. (FWIW, I boot to recovery for cache wipe, otherwise, that's as deep as I've gotten into a Samsung device for quite some time).

I cross all I can !!!:fingers-crossed::fingers-crossed::fingers-crossed:
To get the Note 9 into download mode, do the following:
Turn the device off. Hold the volume down and Bixby button together and then plug in your USB cable that is attached to your PC. Your phone should go into download mode.
As this requires the phone to be off, you may get lucky once the battery runs out of charge.
Good luck

I've never had an issue with holding the buttons too long, but I have had an issue with not holding them long enough. I let go of the buttons as soon as the Recovery screen comes up and I haven't once had an issue with that. I think he'd have to hold the buttons for several seconds past the Recovery screen booting up before this caused an issue.

Okay, now we're on the same page. You have to be FAST with this.
1. Plug in a charging cable. This will give you the LED charging indicator on your phone.
2. Hold Power+Bixby until the charging indicator turns off. Once the charging indicator turns off you have to be VERY quick with step 3.
3. Press and hold Power+Bixby+Volume Up until you see the Recovery screen.
I was stuck in a bootloop after installing a Magisk module, and this happened to me as well. Every time I would power the phone down it wouldn't stay powered down. I had to be very fast to get into Recovery. It took me a couple of tries to press and hold the buttons quickly enough. That was partially because the case on my phone made pressing the buttons a bit more difficult.

Doesn't work as well :crying:
Is there another way to force connection with the PC in order to flash a rom again? Another "magic" application like odin but more powerfull?
The only thing that im aware of is very legacy like QPST. Im not sure if QPST is able to handle the newer phones tho. You can definitely ruin your phone with it too.
Hi again Enzyme
I looked on Google for QPST. But it seems it's only for Qualcom powered phones... mine is Exynos powered. ..
