Axon 7 woun't turn on for no reason - ZTE Axon 7 Questions & Answers

Hello, I got this morning an issue with my ZTE Axon 7. Turned my phone off for the night and when I got up I plugged it in to charge it. The orange led didn't turn on. It tried to replug it but no change. I tried to charge it with my power bank - the power bank indicated charging but the phone still didn't respond anyhow. Then I decided to just turn it on as there was still around 40% of the battery as I remember. However, the phone didn't start. I have tried to hold the power button for a long time, held "turn on" with the "volume up" or "down" but nothing - the phone didn't respond at all while being a brick. I didn't smash it, drop or hit. What can I try else to do besides going to the repair service? Thank you!

Was your battery having problems before this happened, or was it working fine?
My battery is somewhat shot and does that thing where it will shut down when in use around 40%, and then if restarted claims 1%. It can, however, be coaxed to recharge but sometimes won't at first acknowledge that it's plugged in.

[Q] HELP: Battery Problem? Can't Even Turn On!

Hi guys, my HD2's battery hasn't been impressive since I first purchased it, especially after using Android on it, but it seems everyone else's complaining about it so maybe it was just the inherent problem with the phone.
Then comes tonight, I didn't have a chance to charge the battery and it turned itself off. But when I got home and had the charger plugged in, NOTHING HAPPEND, not even the LED light. Nothing happened when I tried to hold the Turn On button, then try holding the Volume up button and the start button to do a hard reset but no luck, NO response at all! I kept it plugged in still nothing happened, though the bottom part of the phone at the back turned warm, otherwise, it's like DEAD....
I think the only cause of it is the battery dies. (I didn't drop the phone prior to the problem.) Any suggestions? Would T-Mobile(U.S.A.) cover a replacement, I had the phone less than 1 year? HELP PLZ guys!
take battery out, plug usb in (wall charger, not pc), and only then reinsert battery.
this prevents the phone trying to turn on when you plug into the wall.
don't be surprised the light doesn't come on.
leave for a few hours.

Why won't my phone stay off??

I have the Bell version of this phone. I received it last week and I love it so far. The biggest issue that I have with this phone is that it will not stay off.
If I turn the phone off by holding the power button, it shows that it is turning off. 20 seconds later, the LG splash screen shows up and the phone powers back on by itself.
If I run it until the battery dies, I connect it to the charger, and a few seconds later I see the battery indicator. Without fail, within 40 seconds the phone powers back up on its own.
I have done a hard reset, and reinstalled everything and it doesn't help. Is this a quirk of this phone? Is there a fix that anyone knows of? I would really like the phone to remain off when I turn it off.
Sorry to hear you have this problem. I have not experience this problem with my phone.
Mine won't stay off if the power cord is plugged in.
So it can't charge while powered off (this is something I used to do to "re-calibrate" the battery on my Kaiser since WM6.x used to get in the way of the charging).
It could be that your USB port is damaged somehow to make the phone think that the power is plugged in?
That's about all I could think of... I find this behavior really aggravating.

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.
Anyway, I'm going to contact their crappy support. Thanks everyone for trying to help.

[Q] Is my Nexus 4 dead? What can I do to recover it?

Hi,
A few days ago my nexus 4 stopped working on me, I haven't found anyone having an identical issue so far.
Essentially, my phone does not turn on any more. I have tried holding volume down and power and this produces nothing. The only thing I can get is the red LED turning on if I hold power for about 10 seconds with it plugged in, it lingers a bit if I release power., but immediately turns off if unplugged.
It stopped working while it was plugged in and at about 60% battery, I had not had any problems with the device in the past, it worked flawlessly up to that moment. The device was running stock without any third party firmware.
Does anyone know what happened, and what I can do about it? I somewhat suspect a battery issue but I'm not sure, any help would be appreciated.
Thanks!
Hi, I'm having the exact same issue. My Nexus 4 (stock Lollipop 5.0, not rooted) died while the battery was 80% full, and the phone was charging. Shortly before it died, it restarted several times within a few hours. The phone doesn't respond to power button, neither it responds to power/volume button combination. When the phone is connected to a charger, nothing happens - no LED, no screen. If the phone is connected to a charger, and I press the power button (or power/volume) for >10s, LED starts blinking in red. The blinking pattern is weird - it blinks steadily 10 times, and gives one short blink. Any suggestions? Or any hope to get the data out?
You can possibly fix this by holding either power up or down for 15+ seconds and then connect the phone to a computer with USB. This has worked for me.
The problem might be that the battery is dying, because I've only had this problem when I've let the battery discharge, and then turned it on again. It's probably a mechanism to protect the battery from becoming "too" discharged, which might break it.
Everytime I had this in the past, I was able to fix by plugging into a very high powered charger (1000mA <) and holding down vol up + power. Eventually, it seems to trickle charge and then start. Once it's started, give it 20 seconds to get a boost then switch it on.

BATTERY (?) Help

Hi Guys, so I flashed Resurrection Remix and it was working fine. Few days later, I woke up to my phone continuously vibrating. Upon checking I saw that it was vibrating because it was doing a boot loop. Unfortunately my PC was broken at the time too, tough week.
Anyway, I let it do it's thing until it runs out of power. It never did. Seriously I waited for a day. When I slept, it had 20% battery (not charging). So I thought maybe, the power button is acting up again which has happened many many times before.
So I opened up my phone and adjusted the power button. Even, holding the volume up while plugging in didnt work anymore.
While I was there I saw the battery connector thingy, I unplugged it and re plugged it real quick without breaking anything. And It restarted and the device worked fine.
But.... The battery icon is steadily at 50% for a min then drops to 0% even while connected to charger. So, I charged it for a few minutes but it doesn't move.
I was about to do a factory reset but it shut down. The battery icon doesn't appear, only the red blinking led light. I tried charging it like that overnight to no avail.
I then tried to remove the battery connector again and as soon as I plug it, the screen turns on then off again. Sometimes it gets to the battery charging icon before it shuts down. If I bend the connector downwards it sometimes turns the screen on and sometimes doesnt.
I took it to repair shops and they said that the problem is the battery and ofc to no suprise, they dont have a replacement.
Do you guys have any idea what happened? Was it a button issue, software issue or indeed battery issue. Before all this happened, the device was working perfectly.
Please help. I miss my phone already.
I think it due socket of battery, can you open the back cover and plugout and plugin this socket, will be OK
