pulsing blue notification, black screen, boot up sound, dies. - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

my note 4 running poprocks and xposed wants to boot up but it never does. it vibrates, gives the jingle, then nothing but a pulsing blue light that goes from blue to almost cyan color. if i pull the battery and connect it to the pc, it vibrates and does a connect/disconnect sound over and over until i hear the jingle but then the light starts again. bad battery? for extra info, the battery on lollipop would give me false reports. it would say like 30% to dead instantly. i was reading it was a lollipop issue cuz others had this same problem. it wasnt that bad tho i would at least get the low battery notification before turning off but recently it never even makes it to that level. so around 20% before it died. also saw in the poprocks thread xposed was killing batteries on samsung devices. i didnt really have any issues before tho until lollipop so thought it was like others had said a lollipop issue on samsung.

How would Xposed kill a battery?
Try this...shut down, pull the battery out, plug the device into the wall, turn it on. Does it work now?

if i plug it in without a battery it does nothing. i tried holding all the buttons for 20secs and it just vibrates then plays the bootup sound then blue pulsing light. also since i tried this last night i would see the screen extremely brief show a line of light when it would either try to start or when i would force a reboot. i would not have noticed it if i wasnt in pitch black.

It should not without a battery if it's plugged in. Sounds like hardware to me.

Have you tried to flash Xposed disabler? Or to flash your whole rom again? Because to me that simply sounds like a broken OS.
Regarding the battery issue, you need to calibrate it after you've flashed a new rom. Use "Battery Calibration' from Google Play.

no i cant access my phone at all the screen is totally black. i was able to odin flash stock rom but after the successful flash via odin i cannot hear a bootup jingle anymore and the blue led is gone. odin is still accessible tho. i was wondering if i should try a mhl but at this point i am not sure if the phone will detect it since IF it is working its still waiting for a setup.
btw who is the developer for the calibration app? there are a few but i would like to have it for future reference.

Strange, so you were able to flash a rom even though your screen was black? Did you enter download mode blindly, or how did you do it?
The dev calls himself NeMa, the app is named Battery Calibration.

blind. i just counted the bootup sequence pressing the keys at the right time. so not sure. gotta buy a heat gun and see if its the screen. also wanted to try mhl but dont know which to try.

I think my battery start failing and phone randomly shuts down in 14 - 25 % battery level, tries reboot itself and usually stuck with blue to cyan pulsating led. Battery pull and connecting to charger always solves the problem.

Damn, I'm sorry. That does really sound like hardware failure.

Hardware same thing just happened to me been on cmremix all year on kit kat bootloader updated 2 weeks ago to 5.0.1 bootloader using the Odin method flashing back to stock than re rooting... Initially phone seemed sluggish but was fine than the phone randomly started turning off would vibrate as to reboot than nothing would appear on the screen but the blue led light would be light up... Went on till last Friday where the phone just died at 60 % phone wouldn't do anything hooked it up to my comp couldn't do anything other than the phone coming up as USB mass storage. Took it T-Mobile they tried everything and it wouldn't do anything I hear lollipop is causing a lot of problems for the 910t anyways got me new phone yesterday its a 910c odd I know and running 5.0.1 thing runs amazing on cmremix 14.2.....I would take it T-Mobile see if its under warranty goodluck

i ordered a heat gun and lifted the display. just as soon as i could peek in, i saw the flex was disconnected. connected the flex and display was back on! luckily it only cost me a heat gun.

[Q] HTC Vivid Black Screen... :(

I don't really know what happened. When I press the power button my phone's screen lights just black then goes blank. When I press my buttons they vibrate but nothing happens. I've tried pulling the battery out several times, leaving it on the charge and all other kinds of things. It is just not working. Does anyone have the solution to this problem?
I'm not sure if this is the same issue..but along the process of rooting my rogers raider I encountered thus during a regular restart. I thought I bricked my phone but realize that the back light was just off and my phone was actually in the recovery menu. I put the phone under bright light and I could just barely see the headings in the recovery menu. It took some tilting and angling the phone just right to see it, but I was able to run a nandroid recovery and get back to a point before this happened. Once again, not sure if its the same thing but try tilting the phone around and using the volume keys to see if you can see the recovery menu in the blank screen.
Hope this helps

This doesn't seem to be the situation I'm having but thank you anyway. +Thanks.
when you plug it in to charge, does the orange charge light come on for 4-5 seconds then go out again? have you tried to hold the vol down key and the power button to get into HBoot? If you can get into HBoot, you might be able to get into recovery.

Yes, that is exactly what is happening. I tried what you said but it is not working. My phone won't go into Hboot.
I think your battery isn't charging (at least that was the issue I was having). Your battery will only charge when the orange light goes on, and if it's anything like what was happening to me, when the orange light went off, that's when the buttons would vibrate. If this is the case, it may sound tedious, but you have to watch the phone. When the orange light goes off, push the home button several times and the vibrating will stop. Then you should see the orange light come on again to signify the charging state. It'll go off again after 4-5 seconds and the buttons will vibrate. Repeat the process of pushing the home button and letting the orange light come on and eventually, the phone should try and turn on. You can try and see if it'll boot, but mine never had enough juice to turn on. So I would pull the battery when the HTC Logo came up and repeat the process with the orange light. This time though, I would hold the vol down button knowing that when it tried to turn on again, it would load into the bootloader. I can't guarantee this'll work for you, but give it a go. What might make it easier is borrow a charged battery from someone and see if it'll load into the bootloader. That might save you from that tedious process.

help the charging light doesn't come back again.. vibration has stopped.. but still no charging light
help pleaseeee
Try different battery fully charged and see if your phone turns on. It it does then plug your phone for charging and see if charges.
Try connecting your phone with usb cable in computer and see if your computer recognize the phone.
there can be three issues.
1. Your battery is dead and won't charge
2. Your charging port on phone is not working
3. your phone backlight is not working.

EDIT: I have stopped looking for these threads. The more I look, the more I find. If the above threads don't convince you that there is a serious issue with the vivid, then adding more of the same problem will no longer help.
I have added this thread to a growing list of similar threads. Please read the other threads and see if your issues seem familiar.
From what I understand... Don't let your battery run out on this phone. Some Vivids kill batteries.
Solution? None yet.
1. Buy a new battery once a couple of months-ish, until someone figures out why some Vivids are eating batteries. YMMV
*OR*
2. You might invest in a external charger and see if that can bring the "Vivid munched" battery back to life. YMMV
I vote to thread merge the above threads if this proves to be the issue.
Hello
I hope to get an answer here to avoid a new thread. I was trying to return my vivid back to gb from ics. I had booted into the bootloader and i dont even remember at this point what i thought i was going to do. I think i got distracted. But anyway i pressed vol down to boot recovery because i was going to do a backup and i looked away from the phone for a minute and when i came back to it the phone was black screen. i hit the power thinking it was just on standby but nothing. I notice it was backlit on the screen but nothing would happen when i press anything. I pulled the battery waited a few min put it back and now totally black with no activity at all. no lights no vibrating no power on, no adb. I have played with a lot of phones and even iphones too so if this thing is fried i guess i will consider myself lucky that its the first ive actually killed out of probably 30 phones. I have searched and tried many things but i cant believe there is no way to recover it. I have recovered a lot of phones I thought I bricked before. any help is greatly appreciated. I was on ics and rooted. I also relocked the bootloader. (i was planning to go back to gb) I thought i had a recovery installed but maybe not. i posted in another thread that i was unable to get hboot by power + vol down method. i could only do it through the tool kit. so i dont know if any of that matters

I hope someone resolves this issue, I've messed with lots of phones. But this is really weird. But I got the same problem where all that happens is that there is backlight on but no boot IMG no HTC logo, no bootloader, recovery. Completly non responsive. At first it wouldn't even power on until I would unplug from a power source. Whether it was unpluging the charger or removing the battery. That's when the backlight would flash. All this happened in the process of flashing a PH39IMG.zip
Is there no other fixes for this? Anyone? Please

I once got stuck on the HTC screen (White background) and found out I could access the device in adb.
So, connect your phone to your pc and check if you can access it from adb (adb devices). If you can try get to the bootloader from here and see what happens (adb reboot-bootloader)!
And if you can access bootloader,
>If you need to get back to stock, get your carrier RUU, put rom.zip from it in an external sdcard and use reboot into hboot again, OR
>if you need a custom ROM unlock bootloader, flash a custom recovery (TWRP is cool) and you may use TWRP to install your ROM
I hope this helps... lets know...
I did mention I cant get it to recognize the phone. So no adb I tried all that before posting. Im afraid im just dead
So I am having the same problem. I eventually got it on yesterday but I turned off my phone and I am back to square one. Would using the vivid toolkit work to reboot to hboot? or am I stuck like this until i replace battery?
4 hours later I am back on!! never turning this thing off again
Had the same problem and just left the at&t store and its the battery. Once he exchanged batteries it worked fine

[Q] My screen is stuck on black ;(

Hey Team!
I've been rooting and tinkering with android phones since the HTC Dream days. Normally, most troubleshoots I can overcome on my own fairly routinely over the years. I kind of feel like I've met my match on this one and I could REALLY use you guys' help!
Here's the story:
So my phone, of course, is the T-Mobile HTC One. What I've done so far? Unlocked the Bootloader. Added a CWM custom recovery. Currently using a 1.29....16 OTA clone deodexed Rom created by Team Nocturnal. I'm using a Faux123 Kernel and have it overclocked to 1.9 GHz with all of his suggested UV settings and Intellidemand Governor chosen. I have the Xposed Framwork installed as well. I've had all of this running smoothly together for weeks with not one random reboot or lockup. The phone has literally been flawless. Until this.....
So, i'm listening to music with headphones plugged in for my Spotify app and relaxing. About 10 minutes into the music session, the music stops. I look down and the app seems frozen. I pick up the phone and turn the screen on. As I swipe the screen to unlock, the phone freezes. I turn the screen off by pressing the power button. From this point on, the screen will not turn back on at all!!
What I've tried:
1) The usual hard reset via power button and volume down. Even power button by itself. The capacitive buttons just keep blinking, but the device never reboots at all.
2) I've tried plugging the device to a computer. The usb connection responds because the computer makes a sound. When I look at the device manager, it does show that it detects the M7 device to be connected. However, when trying to use any ADB commands, it simply states the device is not found (running Windows 8, btw).
3) Freaked out for about 10 minutes before regaining my composure and thinking of one last thing. Only thing I can think left to do is pull the battery. Of course this isn't possible with the HTC One, so my only comparative option would be to let the battery drain completely. The irony is that I boast so much about my phone's battery life, so I know that I'll be waiting 2-3 days for this to happen before I can hope for resolution after.
I've tried to be as specific as possible here guys. I'm far from an expert, but I've owned 4 or 5 android phones since 2008 and have never bricked one. If anyone knows anyway to bring my phone back from this RANDOM sleep of death, please let me know so.
Forever Grateful!
Find a bright light. Hold phone under this light and hold power button down again. Phone lights will blink and the phone will shut off.

I've just been mindf**ked... It WORKED! What kind of crazy HTC Easter Egg is that??? And thank you so much by the way! You have no idea! I use my phone to promote my photography and film to my followers, and I was pretty heart broken lol
Also, what do you think couldv'e caused such a random deep sleep?
Could be the over clock. No need to oc a phone this fast IMHO. The bright light thing is a safeguard against accidentally powering off while in a purse or pocket.

I agree completely. Phone doesn't need to be OC'd. I was just being indulgent I guess lol. That's the first thing I changed when booting it back up. And ya, that's a pretty cool trick sir. This is why I love my XDA Fam! Android FTW!
Also I'd turn off mpdecision in faux control app. It doesn't play nice with faux intelliplug

Yep. That was already turned off based from his recommendations. Only thing I really did was change the OC levels back down to stock.

Dead within 8 hours of use (dead dead. not battery dead)

ok so i've been using it a bit but my battery was 70% last i checked. was playing around with throw and just opened youtube and the screen flickered a bit (black lines) then decided to go black completely.
nothing i do will make the screen do anything.
holding the power button for ages (usually the way to turn off/reboot a phone) doesnt do anything. the backlight is on as i can see that. but nothing is on the screen.
anyone got any ideas on how to force a shutdown/reboot on these?

IIRC the Xperia Z1 has a hard reset button under the sim flap, it's a small red button, give it a shot.
remove sim card and sd card and try again, if it's still not responding do an update repair using SUS or PCC
BTW there is a known fault with the XZU and it could also be on the Z1 as they use similar Firmware, what people have found is that the phone will start up eventually and then they go into the display setting and untick the auto backlight option and that fixes it
I also reboot my Z1in this way when it blackout.

Put it on charge overnight but it doesn't see,m to have taken any charge at all....just trying again using diff PSU and cables but it doesn't want to charge. It recognises that I've out a cable in as I played with the smart connect setting. When it is off completely I get a red light (presumably meaning its charging ) but not in android
Any ideas?
Got it charging again by pushing the red button near sim slot for a couple seconds.
Just had another issue with SD card not being recognised after I removed another (/safely) had to reboot again using power plus vol up as it stuck on the shutdown logo when I tried to power down'...
Wow I can't believe the amount of issues I've ran into within 24hours of having this thing. I really don't know what to do...return it because it sounds like a faulty device (but all the issues are seemingly unrelated) or return and get another phone (is anyone else getting problems like I am?)
Sometimes phones have issues. I got one once that had no speakers or Mic inside... it happens lol
Try to go exchange it, and see if the next device gives you issues.. if not then you're good, if it does pick a different phone..
Do it soon though, most carriers only have a 14 day exchange period, and then after that will charge you all sorts of fees and try to fix your phone rather than just giving you a new one....

sounds like a similar problem I had with my 64gb SD card - as I mentioned above remove all cards then start from there - a reflash of the firmware might help also

Something happened to mine with Youtube too. I'd started a video and paused it on a frame for comparison with another screen. While I was setting the other phone up, the screen on Z1 timed out. I pressed power, the screen come on and flickered, then went black!
Power and both volume keys function the same as the red button under the flap. I wasn't able to reproduce the bug.

yeah i've been trying to reproduce it and failing to. very odd. maybe its something to do with the first time you use youtube and do something specific?
gunna phone o2 up tomorrow and see what they say about all my issues. seems to have been fine this last 24 hours though and in their eyes that is prob reason enough not to issue a replacement.
I've had mine since Monday and this happened to me yesterday. I was troubleshooting sending MMS with T-Mobile tech support (not a phone issue as it was happening on previous phones too) and had to restart the phone several times. I noticed upon restarting that the backlight seemed to be on but the phone was not booting up. Had to perform several hard resets (both with the red reset button as well as the power/volume up buttons) before it FINALLY rebooted and stayed on. While trying to figure this out I ran a Google search to see if others were having this problem. One solution was to make sure the backlight option is checked. I had been messing with settings the night before and must have unchecked it. Since I rechecked it I haven't had the same issue.

[Q] Phone won't turn on, red charging LED stays on, hardware buttons lit

Hey guys,
I left my HTC One to charge and when I tried to unlock it, it wouldn't respond. Right now it's a blank screen, the red LED is on even when I unplug the phone, and the hardware buttons are lit. I've tried to restart the phone by holding the power, holding power + volume down, but nothing is working. Device isn't showing up under adb or fastboot devices. What is going on? How can I fix this?
Help me out. Thanks!

Edit: Recently this has been happening to my phone frequently, but I am usually able to get it to restart doing the methods said above. This is the first time I can't get it to do anything.
Put it under a stronger light and longpress power + vol-
Try this
I was actually searching through old threads and found that same answer and tried it. I can't believe it worked! Thanks! Why does this happen though? And will this hopefully prevent it from happening later on?
Are you rooted with a custom rom?
However, idk why it happened

I have 4.3 Google Edition on my phone with TWRP.
I'll remember this trick next time though. Thanks again!

Why the stronger light? Im confused! :cyclops:
This has worked for me a ton of times too, I guess it must just trigger something with the light sensor the phone has and wakes it up.

It happened to me when i was rooted and used CWM.
It happened everytime i let the battery run down completely.
I havent rooted my replacement yet and when i let it run down, charged it for ten minutes and it booted straight up.
Seems to be an issue with the phone reading the charge state of the safety circuit in the phone. Mere speculation but i havent heard of it happening to anyone who wasnt rooted with custom recovery....

Can you please give me a little bit more details?
I have exact the same issue: The battery ran out completely, then I can't charge it or turn it on.
I have tried
1. with charger connect to outlet, power + vol-
2. with charger connect to PC, power + vol-
3. under desk light, without charger connected, power + vol-
Nothing worked for me.
Some questions:
- Should I connect the cable when I attempt to turn on the phone?
- Is normal desk fluorescent light "bright enough"?
- Should I move the phone under the light first then press the button, or the other way around?
Thank you for your help!
i have the same problem in my htc eye. i tried your solution. but it won't worked for me. phone still on blank screen and red light is on. how can i fix it?????

HTC One Not Charging :(

I don't know what to do now, I'm feeling depressed just by thinking about my problem. Okay, so just to give ya the backstory (nothing big), my phone's battery died when going home to the gym (automatically shut down), didn't think much about it. I got home, after awhile, I plugged in my HTC One into the charger and it wouldn't charge at all!!! :crying: Never happened to me before, I'm running on the latest TWRP, and on the Google Edition rom. Now on to what I did next.
I tried just leaving it on there for a few hours, NOT A PEEP, no LED light, nada just completely dead. Then I plugged it into the laptop USB port, it doesn't recognizes the device but it did install a driver too (forgot what it was called though). And the computer does indeed recognizes the device's existence cuz I hear the computer make that sound when you hook it up to the computer. Also in the the Devices and Printers on Windows 7, it either says Unknown Device or USB Input Device depending on what USB port I hook it up to. And after a few hours charging from the PC, the LED light did come back but only the low battery is dead pulsing (dunno what else to call it lol, its not the solid LED light). And it only does it for a few minutes, goes away then repeats. So does that mean there is some glimmer of hope? I've tried holding the Power button for a minute or 2, nothing. Power button + Vol Up? Nope. Power button + Vol Down? Nope. Do all of those while the LED light is pulsing? Nope. When its completely black? Nope.
So what can I do?! I can't claim warranty because I bought this off Craigslist (plus I'm rooted, so that would be moot anyways), can someone help this depressed as heck man? Its like I'm watching my best friend die slowly. :crying: lol. Sorry if it was a long read, just wanted to put everything in OP, would appreciate the help!

Thank you for responding. Yeah, I tried those 2 steps, so far no good. I'm just very confused because when I charge the One by my PC, the LED orange light just blinks for awhile then goes away, then the cycle continues, does that mean the battery isn't 100% completely dead? god I'm so confused and sad at the same time lol.
This seems to be happening with TWRP 2.7.x. If you can possibly flash a different recovery you may resurrect your phone...

How can I flash anything when the phone wont wake up? ugh, the only hope I'm getting is that the LED is blinking from time to time, meaning there's at least something going on.
Anyone else?
Anyone? I guess theres nothing else to do huh?
*If* twrp 2.7.0.0 caused your issue (which is hard to say since we don't know which recovery you are using) then somehow you have to overwrite the recovery in fastboot.
The phone needs to be able to boot into HBOOT and then go into fastboot. the battery will have to have enough charge for the recovery flash to succeed.
i honestly don't know the next step for your case, maybe someone else can help.
