[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.

How are you sure that the battery is good and charged. Normally after one year if the usage is heavy, the chances of battery down happens. So make sure battery is good. Secondly you mentioned volume down button, how about vol up button ie recovery mode?

This happened to me as well last week. Tried everything but failed.
I did below steps and my phone is up & working
1) Remove the battery and keep it in a dry place for 4-6 hours (Very important step to make this work)
2) Place the battery back into computer and do not turn ON the phone
3) Plug the phone to wall charger and charge the phone for at least an Hour (I kept for 2 Hrs)
4) Remove the charger and gently press the power button for 15 secs
5) This should turn the phone back ON
Above steps helped for me. Let me know if this worked for you also :angel:

Ankush,
In your case I can think of only 2 things
1) If you have CWM installed then
press and hold "Volume UP Key + Power Key + Home Key" all together for 30 secs (may be a min) and see if you get recovery screen
If yes then all is ok & you just need to flash a new ROM
2) If you do not have CWM then
press and hold "Volume Down Key + Power Key + Home Key" all together for 30 secs (may be a min) and see if you get a custom screen
If yes then you can install custom ROM (or original ROM) using ODIN.
Let me know if anything helps you here

Israr

This step kinda weird.. Since I my note never get wet. I hope it will work.. I tried it later.. I dont have much budget to upgadet to Note 3 now. :crying:

Same kind of error
Over the night my phone closed. When I try to open it, on the screen apeared "Insert PIN to decrypt your ~something~ ". I never encrypted my phone so I tried to restart. I got stuck on the samsung logo. Then I removed the battery and put it back in and my device never started again. I have 2 batteries and none of them worked. I can charge the batteries independently and this is not the issue.

Have the same problem right now.. did you find a solution eventually?

Same happened to my device today. Had trouble with some apps before. Wanted to play back a two days old backup. But my phone never woke up again. Shut down forever. Never got to recovery. Had the latest cm11 nightly. Now its dead! RIP. My dear friend. We've gone a long way together. Never intended to replace you anytime soon. But I can't be without a Phone. Moving on to Galaxy S5 now. Hope it can fill the gapp.

Same here, completely dead after a reboot. I took it apart but I see no damage or signs of burn damage anywhere on the motherboard or other components. Is there anything I can do to troubleshoot and find out specifically what happened?

i am not sure, mayb the phone is design to last for only certain years, new apps launch make the phone in applicable for be running with latest apps and everything. Or mayb the phone is design with a timer to self destroy its chip or component after specific numbers of days being used??

[Q] Help - Blank Screen won't boot.

Hi,
I'm running Android Revolution HD 11.5 and everything had been peachy. I was running a back up using MyBackupPro before I updated to AR HD 12.0 and the ONE just went blank. I hadn't even started the flashing process.
It won't respond power or power + Volume Down. When I hold the power button down for 15 seconds when it's connected to a PC I here the USB Connect / Disconnect sound but nothing else happens. It doesn't appear to be visable from either ADB or Fastboot. There is nothing displayed on the screen.
EDIT: I should also mention there are no lights working on the phone.
What do I do next?
Please help! I'm lost without my phone.
Thanks.

This happened to my old nexus one a few years back.. Turned out to be a fried motherboard.. Dunno if its the same case.. Im sorry i cant help u dude

Xperia Z... freeze and brick?

Hey there,
So today I was using my Xperia Z aaaand bam, phone "died".
Battery was at that time 70%, phone was a little bit hot, but in scale of 1 to 10 it was like 6. I had not problems previously with it (besides broken screen that got replaced 3 weeks ago). I was playing a game then suddenly it got closed and my screen got shifted. Like Animation of horizontal menu stucked while going to vertical. I pressed power button many times, I've keept holding it for a short time, long time... nothing. Phone did not respond at all. After 10 minutes it went black. No idea if it went "sleep" or so since power button do not work again.
I tried to reset it with Power + Volume down, Power + Volume up and again, nothing.
I've tried factory reset with Sony Companion but no luck either. Phone is NOT detected by that program.
However, when I plug the phone to PC I hear sound that some device has been found. Phone is presented now as QHSUSB_DLOAD in device manager. I've heard that not a good sign...
When I plug it to PC or Charger nothing happens so I have no idea if phone is getting charged or not.
What even more confusing, when I press power button - nothing, phone is COLD. But when I press Power + Volume down after a while it starts to get warm, after a long time of repeating this really warm.
Any ideas what could I do?
Thanks!

You phone has locked or unlocked bootloader? If unlocked, give a try to enter Fastboot mode and flash any custom ROM

try this. hold power + volume up + volume down all at the same time for about 30 seconds. that is a forced power off/restart. learned that with my HTC when it would lock up from flashing custom roms that did not boot, but had a black screen

I just found out from my local UBreakIFix that Google has extended their warranties for all screen issues on the Pixel 5a, which means you could get a free screen replacement. My warranty expired back in Aug 22 and they gave me a free replacement for my black screen. https://support.google.com/pixelphone/answer/11833075?hl=en
