Concerns about flashing ROMs - what happens if bootloop? - Nexus 4 Q&A, Help & Troubleshooting

Sorry stupid question but the only thing I am concerned about ist the unremoveable battery.. what happens if you get an bootloop after flashing a ROM? Is there something like a reset button? do I have to use a screwdriver? Do I have to wait till battery drains completely?

If it bootloops you wipe and reflash!

Try holding the power button on your Nexus 7. I hope that answer your question.

Sorry i meant hanging on boot I had this the other day with my Nexus S.. The only solution was to remove the battery..

The One X has a function where holding the power button for 10 seconds or so performs a reboot. I'd imagine a similar system will be in place here

He asks how can he get back to the recovery.
I think long press on the power, anyway, you can use adb

Hold the power button to reboot, once the screen goes off, hold the volume keys and it will boot recovery/bootloader.

You can still input ADB commands during a bootloop, just type "adb reboot recovery" and you should be fine.

Hold down power button for 10 seconds, google thinks about the hacking community when it makes irremovable batteries.
Then 3 button combo into bootloader then choose recovery.
*if its anything like Nexus 7's bootloader*

Thanks a lot too all of us.. sometimes a solution can be so easy Tried that thing with holding before but I think I held the button not long enough..

All you have to do is plug in the phone to an AC charger, and the phone should come on.
Sometimes, however, it will show the boot logo, then go to a screen showing you your battery percentage, and not actually boot. No problem. Just pull the battery and unplug. Replace the battery, and while holding the "x" button on your keyboard, plug the phone back in .
If not working..
plug you nexus to USB cable..then restart your pc/laptop without unplugged your nexus..it will power on automatically...
Or if not working...refer to this thread.

[Q] Bootanimation bootloop

Hi,
I am very new to Nexus 7 but experienced in flashing ROMs (as a user been playing with ROMs on my Nexus S).
Now I just got into a bootanimation bootloop and the device won't turn up and I can only see CM logo. That's not a problem as I have CWM and did backup.
With Nexus S it was easy to hard restart the device (take out battery) but how would one do it with Nexus 7? I think that taking out battery is a bit complex and I just don't want to wait till the device is out of energy...
Is there any trick Nexus 7 user can use to hard reset the device?
Hope the question is understandable and not that much noobish. Anyway hopefully someone could advice me... thanks guys
Hold the power button.
Hold the power button for about 10sec. this will turn off the nexus7 instantly. Than you can press three buttons (power, volume up & down) together to turn it on into bootloader mode. Use volume key to navigate and power button to select..
Disconnecting the battery is very easy, but maybe if you just keep holding power button, or with volume down, or up for 20 secs or so it will reset.
I've flashed loads of ROMs, kernels etc now, and I've not been in that position yet, unlike with my galaxy s1. That thing used to boot loop if you so much as looked at it the wrong way lol
I shouldn't have said that. Tempting fate.
Edit: beaten to it.....

Thank you very much for advice!!! I thought there must be something else than just taking out batter! Thank you once more!

Boot Failed, No Command, No ABD

My wife turned on her N7 this morning and it wouldn't boot. Instead there is the droid guy with red triangle saying no command.
Can't use WUG since ADB returns no devices. Tried several computers but none see the device. Unplugged the battery but still the same issue.
Appreciate your help

Turn off the device(Hold the power button for about 10sec) if it's on. Now hold all three hardware buttons(Power, volume UO & Down) togather till the google logo shows up, and this will tur your device on into fastboot mode. Now you should be able to to find your devece from your PC(if driver installed). If you ment "Wug's Nexus Root Toolkit" by "WUG" than you probably want to use Flash stock + Unroot (Can't boot up).

Thanks I tried this. When I try to turn it off it immediately reboots. Tried holding the 3 buttons when this occurs, but the result is still the dead droid with no command under it. The screen where you can select reboot recovery, bootloader never comes up. Confirmed fastboot isn't working.
Any other ideas?

Got the angry droid doing this. One I turned the power on, held the volume key up and once again with the volume key down. What am I doing something wrong?

Even if you just tap the volume button on the Google screen? It should have the same result normally, but something is funky.

Something is really funky. I did the same exercise with another N7 and got into bootloader with no issues
Think it's worth letting the battery die and start over? Grasping at straws

Perhaps, just be aware that running the battery all the way down can also cause booting issues.

Caution: Factory Reset Warning

Im just opening this thread to let any new Galaxy S5 owners know to be very careful when trying to do a Hard Reboot by holding all the buttons down for 10 seconds (volume up and down, power key, and home key). This is known to cause a factory reset to occur upon device restart. Im currently looking into a solution to doing a reboot for an unresponsive device with out a battery pull, but for now a battery pull is the best solution.
Thanks,
Chris

Home button issues

hi guys. today my galaxy s4 suddenly rebooted and now it cant get past the galaxy s4 screen on boot. it automaticly gets into this screen for several seconds, then a black screen and then again. also, when i put in the battery it automaticly starts, and gets in this loop.
i searched the forum a little and i suspect it is somthing with the home button. do i need to replace the whole display to fix thix? or what should i do.
And some important infomation, my home button is a little bent for the last 5 months, but so far it had no problems.
Have you tried to start recovery or download?
Remove the battery, wait half a minute, reinsert the battery and push at the same time Vol Up+Home+Power keys.
If that works you may wipe Cache and Dalvik Cache and maybe it will boot normally again.

power button or home button..? power button looks fine but home is bent and not working for a while.
I agree with @DeepankarS. Seems your power button is stuck.
If so it is a good reason to have the bootloop. Please double check it.

there is a huge difference mate in being okay and looking okay
Thus is not the first kinda problem..the download mode rebooting is directly liked to it..because the download mode will never reboot without the power button being pressed (exceptions ignored)
Try tapping it on a flat surface too...not hard..but ya..
Or search..how people released the stuck power buttons here..
