Black screen boot loop - HTC One A9

I was trying to root this phone so I unlocked the bootloader.
I went on twrp and selected A9 only to realize after I flashed that there is a difference between the a9 and a9s and now my phone is just not booting and is stuck in a black screen boot loop.
If I connect it to a computer it will connect for just a second then disconnect which makes me believe it is not 100% dead
What happens is that it will vibrate connect to the computer for around a few seconds then it will disconnect and then 10 seconds later vibrate again and repeat.
Model is 2pwd200
I cannot do anything such as get into bootloader or download mode. I even tried adb and fastboot but no connection

I've had a bootloop like that before. For me it worked to power-off with volume button up + power. Then power-on with volume button down + power. I was able to get into download mode that way and flash the right boot.img (in my case...)

Doesn't unlocking the bootloader void the warranty?
So if I send mine in, would they charge me any money for it or should i live with the fact that i turned the phone into an expensive vibrator?..
Ty anyway!

With the live chat person they i told them that it just stopped coming on and it only came on sometimes, I asked them what would void the warranty and they said broken screen or liquid damage. I never told them that the bootloader was unlocked. They did say that if there was physical damage to the device they would charge me £27 for it but there isn't so I am going to ship it tomorrow.

I managed to find a way. Every time I plugged the phone into the power adapter, the phone only vibrated every 23 seconds. I decided to leave it for a few days to complete exhaustion and after connecting the power supply for about 2 minutes blinking orange LED. After 3 minutes the phone normally switched on. However, when I tried to restore the factory settings again, I had a black screen. I left the phone again for two days and this time I prepared a SD card with the image from the link:
https://drive.google.com/file/d/0B0r...g5UkZucWc/view
I changed the file name to 2PWDIMG.zip
I started it with the VOL- key and loaded the image. After flash everything works fine.
PS.
Every time the first time I started the phone, the touch screen did not work, I had to restart my phone and then the touch was working. After flash image everything is ok.
This may help you.

You may want to try this, I will if the warranty thing doesn't work out. Credit @looqpl

So they sent the phone back and it is in fully working condition, they relocked the bootloader for me as well and they seemed to have also replaced the frame which had some scratches on it.

[Q] Nexus 5 Dead

Hi everyone, so yesterday I got home, and like everyday I dropped it on the wireless charger. After about 2 hours I took it and it has turned off itself and doesn't react to my button presses or anything. I tried holding Power, Power+Vol Up, Power+Down, Power+Vol up+Vol down, charged it overnight but it still doesn't work. Is there anything else left to do? (Bootloader is unlocked, twrp recovery + franco kernel and stock fw, it was working for like 2 weeks with no crashes).
If you've already tried holding the power button for 20 seconds it sounds like rma is the answer.
Does your computer recognizing your phone?
It does not, the phone isn't turned on, how could computer recognize it? (btw. The phone takes the power from the wall it seems, cause the power cord gives a noise when only it's pluged in without cable to the phone, then I can take it out, it still makes noise, and if i plug the phone into it, it stops making the noise)

It can recognize a phone even if it's not turned on,as adb,and then you can flash recovery,kernel and etc,using fastboot commands.
So go to device manager and see if recognized as adb,if yes,you're good to go,and try to flash stock rom and recovery.
Also you can try to reboot into bootloader using fastboot reboot command.

Ah yes,my bad,sorry. Also,when you took,didn't you notice that it's hot or something like that? Because I've read on the internet that wireless charging can make devices to overheat.

Yes, 2 times it was hot, but not yesterday. When I took it, it wasn't cold or hot, the same as normal phone would be.
Oh, and one more thing. When I hold power button it makes noise like this: h\ttp\s://w\ww.dropbox.c\o\m\/s/d3e0rqtlzm7x2ig/N5noise.mp3 (Remove all the \ from the link)
Barely hearable so I just accidentally noticed it.
Anyways, I'll go for the RMA. One more question, I really doubt it's possible but I will ask. is there a way to transfer all files from the phone if it's not responding to anything?

If your sending it to google, then you don't have to worry. However, your device is fully dead, right? They will most probably swap the mobo or just send you a refurbished piece.

It's making some kind of a noise when trying to turn it on/charge it, and doesn't react any other way, so yea, dead.

[Q] Nexus 5 constantly rebooting at 'Google'

Guys my gf's Nexus 5 shutdown today and just refuses to boot up. It doesn't do anything with any of the keys pressed in any of the combinations that are defined. But once it is plugged in to the charger or USB, the google logo pops up and the phone keeps on rebooting to that logo. If the volume down key is pressed when this is happening, the fastboot mode is visible for a second and the phone keeps rebooting. No action can be done in the fastboot mode due to the quick reboot. I am attaching the video of the problem. Any help guys?

If on battery, then the phone does nothing. If plugged in to charger and the key combination is tried then the phone keeps on doing as shown in the video.
Don't know what's going on.
Try doing that but with the phone connected to a PC that has adb and fastboot installed.

You have a fauilty or a stucked power key.
If it is just stucked then you can unstuck it by abusing the power key or taking the phone apart.
If it is fauilty then you have to claim your warranty.
If you disassemble the phone you will void your warranty

A few days back, she had got the power button fixed because the power button response had become intermittent and the phone was rebooting randomly. She had taken the phone to a LG service center first, but they told her that changing the button or trying to fix it might damage the board and told her to change the board altogether. So we took it to a local repair guy who fixed it and the phone was working fine till yesterday when it shutdown all of a sudden and then the rest is history.
Note: The phone is not under warranty as the phone was bought from Dubai and we stay in India. No international warranty.

Then you have to visit that local repairer guy pay him to replace the power key again or pay LG to replace the mother board.

Yeah the repair guy you dealt with must have fixed the button short-term but in doing so inadvertently caused it to short out. Meaning it needs to go back to a repair shop (better one) and cross your fingers that it didn't short out more important components

Okie. Will take the phone to LG tomorrow or over the weekend.
Guys please clear my one doubt. If it's the stuck power button, what does it have to do with the phone not doing anything when on battery but decides to go till 'Google' when plugged in?

Did you get it fixed? I have the same issue and I've tried many ways to bring it back to life. My last step will be taking it to the tech support, because I live in Brazil, and I'm pretty sure they will charge me expensively as hell.

Had my Nexus 5 for about a few month now, and have loved it till this morning, it decided to just shut off (full battery too) and i tried to turn it on and it is now just constantly starting up to the "Google" splash screen then shutting off.
Sometimes it gets to the the 4 color circles then shuts off.
I want to enter into recovery mode, but I have no time to click recovery mode as it reboots frequently
One thing i noticed when it did boot up was the power button seems to be extremely sensitive and volatile
I had this same problem.. It constantly rebooted and wouldn't let me get into recovery.. Every time I plugged in the charger it would reboot also. You have to let the battery completely drain.. I gave it a couple weeks.. then tried it again and it worked.
Found a solution
Well same thing started to happening with me yesterday after installing android L's developers' preview in my nexus 5. It worked well for first 4-5 hours but then after terminating a phone call when I put it back to my pocket problem started. I searched many forums for solution then I decided to re-install from image. I connected my phone to My PC (Which had driver installed & fastBoot setup) dramatically my phone started working well. And I detached my phone from PC. So I thought it might solved because after supplying charging. But after 3-4 hours it started again so I directly plugged in to electric socket but it kept on rebooting. Then I turned on my PC and attached my nexus 5 with it. Again it started dramatically.
Still I don't know the exact reason behind it. But good new is my phone is still working since last 16 hours... But I took care of not to launch some apps listed risky for developer's preview. So I thing some incompatible app launch may be a reason... but still its only "may be"

Nexus 5 wont boot

Last night, my nexus 5 suddenly rebooted itself. When it restarted it was in a boot loop. but not a boot loop that i can get out of.
It just keeps going round and round almost as if the power button is stuck. however the power button is not stuck.
i cant get into recovery to clear the cache as when i boot into the bootloader it just automatically restarts again, i can move one option up or down and that is to shut down or reboot into bootloader, but not the second move that would take me to recovery.
i have now taken the back off, and unplugged the battery in the vain hope that it clears through whatever is causing the issue but im not convinced it will make any difference.
Please advise. i'm completely housebound and cannot walk due to having a knee operation, and completely dependent on my mobile if i have an emergency.
i've tried Kwoggers out of the box fix from his 2.1.2 toolkit but this didnt work as the phone wont stay in one place long enough for it to get a fix.

If it reboots, even in bootloader, then it's either a broken power button or a broken motherboard.

the reason i dont think its the power button is it just stops doing it and just switches off.
when its plugged in it just reboots around the white google logo, constantly. without being plugged in it goes to the 4 balls and reoots

[Q] Nexus 5 constantlly turning on and off

For quite a long time I did not make any change on Nexus ROM or applications, but yesterday my Nexus turns off while I was web browsing. I tried to turn it on but it refuses. It is only possible with USB cable plugged in, but then it constantly turns on for 1 second and then turns off, and this is going in endless loop as soon as USB cable is plugged in. But with unplugged cable NEXUS can not be powered on.
The video can be seen on this link
https://www.dropbox.com/s/cvyxii4ctm4aqgu/VID_20141110_190522.mp4?dl=0
Yesterday I somehow manage to get in recovery mode and I wipe cache and Nexus boot ROM, but after 30 minutes of usage it again turns of by itself. After that for more than 100 times I tried to get to recovery mode but I could not.
So, I think that my only chance to wipe cache and put new ROM is through ADB. But I do know how to do that. Can anyone help me?
P.S. I both my NEXUS in US, but I live in Croatia (EU) and Google tells that they can not make exchange for other NEXUS (although my phone is under warranty) because they can only do that for postal address inside US. Because I do not live there and any of my friends or relative will travel in US soon my only way to get my NEXUS working is through ADB.
sounds as your power button is "stuck'.

It usually helps the button back out again, I think you should RMA to LG, I'm sure they're worldwide. You could always open up the phone and try unsticking the power button if you can't be bothered sending it back.

Power button is not what cause the problem. I found many reports about the same problem, like on this page
http://www.reddit.com/r/Nexus5/comments/29tr5n/nexus_5_wont_turn_on_google_screen_keeps_flashing/
but nothing which I tried did not helped. But certainly power button is not causing the problem.
When the problem appears for the first time I manage to get into recovery and wipe cache, and after that phone booted ROM. After 30 minutes of working phone turns off and now I'm not able to get even into recovery.

So, since shaking, hard wacks, and anyting physical did not helped after your post I dismantle my phone and without back plate and upper plate on chips my phone works perfectly. So it seems that upper plate which covers chips is the cause of the problem.
For me, not even disassembling has helped, so I bought another motherboard and put it into my phone.

the problem occured and i found what it was my power button it wasnt staying in place like its tilting so now i got to buy a new button for it :/
As far as I remember, the button is soldered to the board, and can not be bought separately. I know the second thing for sure, since I was also only searching for a separate button in the beginning...

blocked on black screen

Hello,
Ive tried to look for a similar situation in other thread but each case is different so i open a new one.
This morning, when i took my idol 3 the screen did not switch off when pressing power button. I thought it was battery but when i plugged charger,nothing happened except the led is on continuously. I kept power button pressed for 10 seconds. The phone vibrates shortly but still a black screen, no sound and no reaction from the touch panel. Power+vol+ did not led me to my twrp recovery. What can i do now to get it work again? The phone is rooted with Rom Eu 4.2 from murigny64 and it is the first time i encounter this issu. Thanks in advance for helping me
Tonight i disconnected the battery for about 30min then connect it again. Then i tried to start in recovery: Just a vibration but no display and no sound. I unplugged/plugged the battery again and try to start. Same problem. What the hell could happen? Maybe a deffective hardware
Insist on boot ( normal or in to recovery with vol + and power).
That is a hardware brick.
Happened to me to some times, insist, it will unbrick

Hopelessly i tried to restart several times before you post your message. But im gonna try again.
I charged the phone all the night but nothing better and the phone is not detected on pc so no adb action possible.
Maybe the battery is dead...

Can be, can be to... To bad if is battery.
But still trying to boot, is very difficult to.
.
thank you for advise but it's still not working. I spend about 30 minutes trying different combination of button: power pressed until it vibrate, power+vol up, power+vol down, power+vol up & down, discontinuous press of power with charger and no charger....and so on. Its a complete failure.
If it is the battery, there was no sign of weakness before (short life, random shutoff, ....) . It happen suddenly: I lock my screen before sleeping and the next morning no way to switch it on again.
I thought I would avoid problems for long with a twrp recovery, a backup and adb tools on my pc.....but for hardware issues its useless.
How can I be sure it is battery before purchasing another one ?

There is also possibility that your screen has been broken

If it was the screen the touch panel would work and i could sense vibration when typing the pin code no?
The led bright continuously when i plug instead of flashing slowly as it used to do when charging. That why i think its battery.
...and when i start in recovery the phone is not detected on my pc
That's hardware brick. Don't give up, try to boot, normally or in recovery, keep trying it will boot.
Have you tried to open the phone and disconnect battery? Custom ROMs made me similar issue a few times.

Therefore the back can be dismantle and we can access battery and that s what i did.
Yes i disconnected it for several hours and pluged it again but it gave me the same result. And now it doesnt vibrate anymore when i keep the power button pressed a while.
I purchased a battery on internet and im waiting for delivery to test if im right or not. Il feedback about the test.
Anyway its nice from you to look for any solution. Thanks

I guess you did everything properly, so just one thing: at first time when I did this, I choosed the wrong cable (which didn't 'reset' the phone), so I hope you pulled both out.

I think i choose the good connection: This is the one over the battery with 6 wires: 2 red, 2 white and 1 black (see picture attached). I just left it with a small screwdriver to disconnect.

Yep, that's it
Hello,
I received the new battery today.
So i unpacked it, i unplugged the old one and plugged the new one ...and guess what happened......the same bevahiour as with the old battery: when i press the button power, it vibrate but it doesnt start neither in recovery nor in normal mode.
I just precise that the new battery is charged at 50%........:crying:
So the problem is not the battery but it was the only thing i could test by myself before sending the phone to alcatel for repair.
Im still wondering what could happen to my idol 3: It had been woking perfectly for months and one morning with no warning, it refuse to switch on. Ok sorry for annoying us and hope it wont happen with yours.
I hope alacatel will apply the guarantee although the phone is rooted and bootloader unlocked....because its a hardware issue i think.
Hello,
Just to conclude. The phone got back from repair after 10 days. They have changed motherboard, battery and also the back that was damaged. Its a brand new phone .
