[Q] Strange Reboot Loop, searched forum Not Addressed

Hello All
I did search the forum and still not answer for the stranger reboot loop.
I got a phone call, and answered it. The reception was crappy and hear no voice. I then looked at the phone to see if call had dropped and it was frozed on the incoming call screen. I then pulled the battery and pressed the power button to turn on the phone and It would not power on. After multiple battery pulls and many many power button presses, still nothing. It was like it was out of battery. It was stitting on the home charger before i left the house. Prior to this the phone worked fine. Over the past week or two I had to do a battery pull may be 3 times.
I got to my car and plugged it into the charger and the orange charge led came on, on the front of the device. I then pressed the power button and it vibrate once as normal and then went to the multi-colored nexus "X." he screen went black and then vibrated once again and and was back at the mulit-colored "X." Then the loop starts.
In between the restarts I try to get it to boot into the bootloader by using the "vol down and power" and the "trackball and power button" and the white screen for the boot loader flashed for a milisecond the goes to black. As long as I hold the "vol down" button the while bootloeader or recovery screen flashes every 4-5 sec for a milisecond. As soon as I let go of one of those button, it automatically goes to the full reboot loop.
THis all happens when it is plugged into a power source. As soon as i unplug it, it goes back to the power button not responding. Again it acts as if it has no battery power. But it is in the 90%.
So i am unable to do any other step as in reflashing, and or doing a recovery.
ANY IDEAS any one.
I was running Cyanogen RC3. the latest rom with amon RA 1 7 1, korean radio 5.0.8
It was running perfectly up till today. when it went into its loop.
ANY HELP WOULD BE AWESOME
THanks in advance

Plug it in to the USB, adb reboot recovery, reflash rom. Or even wipe and reflash if needed.
Sounds like it could be hardware the way you have to hold the keys down and you said it wasn't responding to the power button press.

ok thanks, ill give it a try.

here is my only issue. I am not using my original computer Mac. I just sent it out to apple for repair. So i am using my companies computer. I need to set up the AndroidSDK to be able to talk to the nexus. Since the phone will not turn on i can not load the drivers. and ive tried every way and it has not installed and i cant check because it wont stay on. it just goes to the loop. and it wont turn on if its not plugged to a power source.
Any ideas or suggestion.
SOrry I am an noob, so could you please be specific in your instructions.
I as of right now have insalled the Android SDK and i am unable to see the serial number (working on an old dell, running XP sp3) because it wont turn on.
It cant manually install the drivers because I cant turn the phone on to specify the drivers.
and
I using USBDeview, the phone also has to be on to erase all HTC previously installed drivers. i think. but there were none in the usb log...i think becuase they didnt install...agains because it would not power on...:-(
any ideas...please
DD

Also
Sorry excuse me if its a sort of a duhhh question...
even if i am able to load the device bridge, if the phone will not boot can i still flash another rom, or do a recovery. The phone is not getting past the Multi-colored "X" ???

It should still read the commands when it's trying to boot. You don't need to turn the phone on at all to be able to install the ADB drivers, they are independent of each other.

As strange as it started, is a strange as it went.
This morning open the phone to pull the sd and the sim to put it in a throw down phone. I replaced the battery and cover and just hit the power button. The phone does a full boot and it appears to be working properly. the sd card and sim are fine. I the odd thing is i did this multiple times yesterday and last night. I pulled both sim and sd, replaced the battery and tried to boot with the same issues as named above with nothing different.
I left the phone on charge last night and it was charging for close to 8 hours and it was still showing the orange charging light.
So after it booted this morning, and i checked everything. It showed the same amount of charge as yesterday, right before it froze, which was 75%. So that is another strange occurance.
I plan on reflashing the rom and seeing how things go.
I thank you for your assistance and time.
appericate you helping out a clueless noob.

[Q] Bricked? Stuck on either white AT&T screen or grey, frozen battery screen, no USB

[Q] Bricked? Stuck on either white AT&T screen or grey, frozen battery screen, no USB
While trying to install Cognition v2.2b3 via Clockworkmod (from stock at&t 2.1 froyo) something happened mid-install and my phone ended up rebooting, and I have not been able to turn it on since.
-When attempting to power on normally, phone shows white AT&T screen and hangs there
-When attaching USB, phone shows battery screen but battery is all grey and rotating progress icon is frozen. Does not appear to be charging.
-Computer does not recognize phone in any state. Latest USB drivers are installed and I have had no issues connecting via USB previously.
-Cannot get into download or recovery mode using any volume/power button combination or through adb. Also tried attaching USB with ODIN running while attempting button combinations, inserting/removing battery etc, still nothing.
Has anyone else experienced this? Anything else I should try?

Go into Download mode, hold both volume buttons down and plug your phone into USB. If it doesn't work than pull the battery and try again.
If that doesn't work keep trying until it does. I'm serious, it took me like 40 tries last night to flash stock with the 1 click and then finally get cognition running (that only took one flash)
Odin is a piece of crap, it works maybe every 10th time for me. I've never used the rom manager to install roms, always use clockwork recovery. Less to go wrong if your in recovery mode I suppose.
But literally just keep trying until it works o.0

Hi. I've experienced exactly the same this night. Try this: forum.xda-developers.com/showthread.php?t=775911 it helped instantaneously.
BTW, you really need to wait at least 10 secs after removing battery.

I have the exact same problem.
My battery screen shows up with nothing but a flash loading icon and a grey battery. When I simply turn my phone on its stuck in ATT boot screen. I tried the instructions many times trying to get into download mode but right when i put it in the battery while holding down up/down/power it simply just shows the "frozen battery charging" screen again.

[Q] Stuck on stupid:can't force download

Hate to be that guy, but alas I am
I flashed my Captivate with the latest Twingerbread ROM. Everything was running nice and smooth until I decided to use a Galaxy S Mod tool from the market place to change my battery icon.
Long story short the phone is now stuck trying to boot. It will run the Twingerbread loading animation for a few seconds, flash a screen that says
Candidates:
Preparing external SD Card
and then continue with the loading animation.
Before this happened I had been able to force download mode using only the volume up/down buttons, that is no longer the case. I have tried using adb to access and force download but the phone isn't found whether powered off or in it's current "loading" state. ODIN is able to recognize it as a COM:7 device but fails to flash it.
I'm in a bit over my head here, anyone have any suggestions on how to fix this?

Try this:
Open Odin and plug the cable into your computer only not your phone
Remove your battery from your phone
Wait 30 seconds and put it back in, don't turn your phone on
Hold both volume buttons down and then plug the cable into your phone, it should go into download mode.

Thank you for the suggestion but I can't get that to work for me. I tried it multiple times but it simply loads the charging screen. I have heard the term jig thrown around a time or two in here but can't seem to find any more info on it. Would that be my next step?

Yes if that doesn't work then you will need to get a jig to force download mode. Look here....http://www.mobiletechvideos.com/blog/?page_id=100
Good Luck

Nice, I don't have to make it even. Thanks for helping the noob out, jhernand1102. Hopefully this cures my issue.

[Q] stuck at "dual core" but now can't even fastboot?!

I bought one of the refurb'd bionic's a couple months ago. I've rooted and masked the wifi tether, but nothing else, no custom ROMs or anything. phone's been working great for the past seveal weeks since those changes were made, several reboots, etc. no problems until last weekend.
I randomly found my phone stuck on the "dual core" screen one morning. it must have rebooted overnight and been that way for several hours as it was quite hot. I did a battery pull and tried to turn it back on, got nothing. plug it in to the charger, nothing, no leds, nothing. several battery pulls later, still nothing. try to enter fastboot/bootloader by pressing power + volume up/done, nothing. plug it into the computer, nothing.
I'm sorta fearing its been hard bricked (though I have no idea why... i wasn't loading ROMs), except, the other day, after leaving the battery out all night, I was able to get it to turn on, it booted up to the home screen, but before it was usable, rebooted and was stuck on "dual core" again. messing with it some more, I eventually got to the bootloader screen. I wish I had siezed that moment, but i didn't. Messed with it some more yesterday, saw the 'dual core' screen again, but couldn't get it into fastboot. its very hit or miss and I can't do it consistantly, but on rare occasion, it does seem to want to come back to life.
any advice on what happened? where to go from here? and if it can get it back into fastboot? I'm hoping i can and rsdlite will recognize it and I'll try loading 902 fxz back on it, but sure could use some advice to save this phone... no insurance and it was a refurb thats been rooted, I don't think verizon will be too much help.
THanks

Try this
Little known hidden key (actually button) sequence: press and hold both volume up & down then hold the power button ten seconds (five should work, but ten always gets it). You should boot into fastboot mode, then flash 902 using a USB cable. You do NOT need to delete data! Check the batch file and REM out or remove any line that says it will. Worst case, Motofail after that will give you access to your latest CWM backup, assuming you have one, just restore that once you have root.

What he said and also you may need to charge your battery.

It could just be a dying phone, I came across an Atrix basically in the same situation. The radio in it had died, so the only way to boot the phone was to skip booting the radio, but if you hit the phone application it would crash the phone.

OnePlus 3t; Stuck in a endless cycle of restarting

**PHONE SPECS**
OnePlus 3t~ ver. 8.0, storage is only half full, no water damage or any damage of any kind
Like the title says, my phone is just restarting over and over again. This happening out of no where yesterday. I simply put my phone to charge and when I came back it was like someone is holding down the power button.
What I have tried so far is get to screen with the Chinese letters,^sorry ^I ^don't ^know ^what ^this ^screen ^is ^called .^All ^I ^know ^is ^that ^you ^hold ^volume ^down, so I can factory reset it but, the phone quickly restarts so I was not able to.
I also tried using a oneplus3t unbrick program I found while searching for possible answers but that program was unable to work on my computer. Hopefully someone can help with that
The good news is that I was able to back up my phone so I have no problem resetting it.
All help is welcome; Thank you!

If you hold the power button for a long time does it shut off and stay off? If so. That is the time try and enter recovery. While it's restarting it will be difficult. Try with the phone off. If you can get to recovery you should be able to either restore to your backup or flash a diff build. I would also download the latest stable build to your PC first. If you can get to recovery and connect your phone to the pc and have it recognized by the pc, you should be good.

Sorry for the late reply, I was in class
When i hold the power button it does not turn off it just continues to restart. The only way it "turns off" is when I plug it in to a power source or my computer. But it will turn on and do a bootloop at random intervals and at random times. When it is plugged in my computer, I can not find it in the device manager. And when it appears, it quickly disappears.
Speaking of downloading a build onto my computer, how would I go to do that? Is there a detailed tutorial I can follow.

Can you get into fastboot (power & volume up)?
If you can you could clear the cache via command line to see if something in there is the culprit.

Update
Out of frustration of nothing working, I left my phone to die for 3 days straight( i didn't touch or move it) and on the 3rd day I charged it. And it works now!! Idk if it was hardware or software but it works and I hope it continues do so.
Just as a note this phone as no water damage and very minimal physical damage so I have no idea what happened. Thanks to everyone who pitched in ideas
