[Q] stuck on battery logo when rebooting when its charging?

I have a problem because everytime when my phone is on charge (doesnt matter if its USB cable or wall socket) and Im rebooting it (power -> switch off - > and power it again) the system will not boot up. It will just stay on black screen with battery logo. I never checked if its a problem with stock ICS or Revolution MOD. Anyone else have such a problem?

I have the same problem, it's annoying to have to remove the battery just to turn it back on.

I think most phones do that, on my Optimus 2x i can boot it by using the power button again.

Power button is not working. Can someone confirm if its a stock ICS issue or because our phones are rooted

Dude Android has nothing to say about a pre-boot enviroment like the charger.

Have it here as well. Have pulled the battery both times I have done it so far.

Same problem here. I have tried both Android Revolution and a stock F build.
It sounds like it might be something to do with the bootloader unlock process?
EDIT: Flashed Paul's ir3 release and ClockworkMod again and it's charging fine now. Very strange.

Phone goes into random boot loops and vibrates? Any help

Okay so ive been running jmt v8 for about a week on my phone and everything was running great. Then yesterday morning my phone became very slow and unusable. Then i started getting the error message acore system has stopped working and the phone would randomly restart and then it would start vibrating then stop then vibrate again and so on. So i insalled a new rom and i stopped getting the core system has stopped error but i am still getting the random reboots. And the screen also wakes up by itself. Please any help or suggestions would be greatly appreciated.

I just had this fixed. There's something wrong with the power sensor, especially if it tries to boot the second you put the battery in without touching the power button.
Unfortunately you've been rooted now and because of the issues, you can't flash stock and reset the root count. So you can't sent to your carrier.
Fortunately, http://www.mobiletechvideos.com fixes EXACTLY this for $35 minus shipping it to them. I got my phone back today and it's just the way it was ROM wise and all my files are there and the issue is fixed.
This is a pretty common T989 issue.

I can boot into recovery but its tricky because I have to press the buttons perfect or it'll just reboot. I believe the problem is with the power button and ill probably get it replaced.

For anyone with key issues and need to get into recovery or download mode there are adb commands that do this. We get too comfortable with apps and forget about the manual way of achieving a lot of the same tasks that apps provide for us.
From a command prompt:
adb reboot recovery
adb reboot download

hey guys. after the ics update my phone started to lock up and its not rooted. now all of a sudden when i put the battery in it it vibrates once then starts to load and gets about half way and stops. then it turns off and just vibrates a few seconds and vibrates but the screen never shows anything. tryed using just a usb with the battery out and it skips the load screen and automatically starts vibrate looping. the power button seems stuck but i dont think i can fix it any ideas?

Hey everyone! I have a similar (but not quite the same) problem. Every now and then my phone "tells" me to restart it for maximum performance. Every time I restart or just turn on my phone it goes through the boot cycle, including a message that says "android is upgrading" (I got the ICS upgrade from Kies prior to rooting my phone). Then, all of a sudden, the phone doesn't work, and it starts the boot cycle all over again. This happens several times in a row, which for me is a safety issue because I'm not able to call Big Jon (my husband) to get me from the train late at night. Any fixes for that? Thanks.

Damn! Just found this thread...sounds like what my phone started doing today!!
I was clicking around on gmail, then back to home screen, the camera FLASHED all by itself without me doing anything, then started the boot loop thing. Clicking the power button only made it worse. Finally was able to get into recovery via TWRP...but that was weird too. I did a factory reset/wipe and was going to reinstall The Sith ROM that I was running, but it just rebooted and loaded up The Sith anyway and it should have been cleared. I then tried to restore back to Beastmade ROM, restore was very quick and said successful but it booted back to Sith.
Now the power button is hyper sensitive! All I have to do is brush the power button and it will light up the screen. Touch it too long and it will bring up the boot menu. I'm afraid to actually CLICK the button as it might go haywire again.
WTF is going on!? This all seems really odd that it's going down with some of these new ROMs being released. I wasn't even touching the power button when all this started. The weird clicks and flashes didn't sound good when it was all going on.
Has anyone tried flashing back to and OLD rom to see if it will fix it?

change settings to interactive/deadline

[Q] URGENT HELP:Phone won't boot

I've had they Hercules for just over a year now but have only been using it for the past four months. I have only downloaded educational apps. However, yesterday i was not using it and came back to find it vibrating every 2-3 seconds. I removed the battery and left it out for an hour. When i replaced the battery, the phone began to reload but stopped during the boot,made a noise I've never heard before and began to vibrate as if going into recovery/download mode. I have been running ics for the past 4 months. The phone does not boot at all and is very frustrating . I have also tried charging it with no luck. Can anyone assist me with this problem??

sounds like you have the dreadful power button fail it gets a little jammed up try sticking a toothpick or something skinny in there and wiggle it a bit see if that works for you if not check if your still under warranty are you rooted or stock ICS?

u have a bad power button. try unsticking it.

Agreed. A friend had a similar issue and his power button was stuck.

I'm rooted and the warranty is up

Strange enough this just happened to me 10 minutes ago. I did manage to get the phone to boot after slapping the hell out if my power button which gave me the only means to get into recovery so now I can comment from experience. Ive been running pac for 3 weeks. Just yesterday my phone started doing really weird ****, dont know if it's just coincidence, calls would go through to random people, every time I clicked gallery I got a random reboot, I couldnt call voicemail, and trying to change wallpapers gave a reboot. Today I was changing a wallpaper and boom random reboot then began the loop and vibrating. A few things I noticed while this was happening, if I attempted to go into recovery the samsung splash screen appeared followed by the stock kernel splash( samsung and the blue bar at the bottom) which made me believe it wasnt the power button but indeed rom or kernel problem, also my led flashed once while going through the vibrate loop and I know the power button has nothing to do with that. I did manage to get pac to boot about 4 times by slapping the hell out of my power button but it went back to the loop after a few seconds so the next time I managed to get it to boot I held the power button and booted to recovery. Once I was able to get in to recovery I restored a liquid smooth back up. Ive powered the phone off and on with no problem. Now I'm just waiting to see what happens through out the day. I was running pac with cerux when this happened. I truly believe this is not a hardware problem at all until I get it again with another set up. If you need help I getting your phone to boot I could possibly be of assistance so pm me unless you want to keep getting responses from people who haven't experienced this at all. This was the single most scariest experience Ive had since I ve been flashing, even worse than my brick because I knew I bricked immediately.

my nexus gets stuck at x loading screen!

I need some help with this issue. My tablet is stock out of the box. I have been using it since last Friday. But today I turned it off then after an hour later I turned it back on, it gets stuck at x logo. I really dont know what issue is called? I have tried to restart the tablet several times by holding the powerbutton, but it is still stuck at X logo, and I have tried to use recovery mode in bootloading, but I get no command message everytime.

If you don't have a lot on your nexus and don't mind wiping then just hold power and vol up, which will data wipe your nexus. I know when I first started my nexus it would go to the welcome screen and then bootloop if I didn't click the next button fast enough. But you're saying you've been using it so dunno.
or you could fastboot then flash twrp and try to clear cache/dalvik and see if that helps

First hold power+volume down to go to boot loader, then select recovery, then in recovery do power+volume up. I think that's the proper order.

Just as a side-note, I've had 2 Nexuses 7 (the older versions) and BOTH of them did this to me when updating to a higher version of Android. I swore like a madman as I had to hard-reset the device thus losing nearly all my data. If anyone reports that this happens with the new Nexus, it might be the deciding factor for me to not buy it... unfortunately...

It's really easy to do. I had the same issue as you and a factory reset corrected it. Just make sure to follow the steps and everything will be fine

I'm having the same issue since last Saturday when I picked it up. Still running stock and it just would not boot up and it seemed no one else was facing any problems. So I did fastboot unlock, it reset the device and cleared all data. Since then, I've been running stock, and I'm still facing the issue. I'm not sure if it's actually an issue with stock or not.

Just had this same problem on a brand new nexus 7 only a couple of days old. I really can't believe Asus/Google has these problems in 2013. Unbelievable.

Do you have a custom recovery installed?

Just happened to me very weird.

It happened to me with old. Exchanged it. And happened today in new one this time I was able to turn it off then try again and it booted. Started after 6 days of flawless use. Weird.

Just happened to me...
I just had my SECOND one do this to me this morning. I bought the 2nd Gen Nexus 7 last week and it did this within an hour of using it (after an update). I took it back and got another one. This morning the second one did this after a simple reboot. I never had this trouble with my 1st Gen Nexus 7. I'm about to start trying the tips listed in this thread before I return yet another one. I'm wondering if this is the first reboot since the 4.3 update... maybe that is the issue.

Try Fully Charging?
Something similar happened to me on the first one I got, not sure if it will happened to the exchanged one since I only had it for a few days.
It happened after I shut it down one night, battery was about 80% or so. Next morning, I started it up and it actually loaded up fine but after a minute, it just rebooted, stuck at the X, then rebooted to the Google logo, over and over again. Did a factory reset and cleared the cache and still would get into the boot loop after 1 minute of successful boot up. Battery was about halfway when I decided to just charge it fully.
After the battery was fully charged, everything worked fine again. I suspect that the battery was run down next to nothing, but indicated that it was halfway. To me, that indicates a hardware issue so I exchanged it. I am wondering if they are using cheap batteries to keep the cost low. Not sure anyone else has seen this happened to them.
Anyway, if you watch the X, the colors move around, then suddenly stop after a while, it reboots again.

Same thing happened to me this moring around 3 a.m, shutdown and restarted and it was still stuck on the x screen. Tried wiping the cache from recovery and nothing. Had to do a factory reset in order to get passed boot screen. Tablet is working normally now.

Getting stuck on boot screen occasionally occur on 4.3. It seems like an OS issue not the hardware issue. I have seen it once or twice on my stock non-rooted Nexus 4 running 4.3. Never happened on 4.1~4.2.
On the other hand, if you have rooted your 4.3 device, the chance of ****up at boot rises dramatically. The toolkit is, while an admirable work, not perfect and you have no one but to blame yourself.

Phone Hangs on Boot Animation (CM 10.1)

While using my phone tonight, the battery was really low and the phone died. I plugged it into my charger and tried turning it back on after a few minutes. Unfortunately, the phone didn't start. It simply showed the CyanogenMod boot animation and nothing happened. I tried pulling the battery and turning the phone back on, but the same thing happened. I'm running CyangenMod 10.1, specifically cm-10.1-20130121-EXPERIMENTAL-toro-M1. I've been running this build for months now and have never had this problem before. I was using my phone in the hot tub shortly before this happened and am wondering if it got wet and damaged. I checked the water sensor, but it was not set off - there are still little red X's on the sticker.
Thankfully, it still lets me boot into the bootloader by holding the power button while holding volume up + volume down. I tried going into the recovery menu and doing a factory reset, but it didn't work - it still gets stuck at the boot animation. Anyone have any idea what the problem could be? Thanks!
