Now when I plug it into the charger, it just goes to the Core Cell splash screen, for like a split second then turns off, then does it repeatedly... I donnu, how to charge my phone, I donnu what to do, please help.
like i ttly hope someone can halp...i donnu wut it iz.
i wuz in yor phonez checking ur batterys, and it looked mkay to meh.
lol.
I don't know WTF is going on here... My phone is like constantly just reloading the same thing, every 4 seconds, it just loads the Splash screen for less than a second, turns off, then does it again, this is while it's plugged into the charger, when it's taken off the charger, nothing happens, I can't ever turn the phone on...
You've obviously got a bad phone.....take it in to your local store T-mobile and have them look at it.
Have you tried plugging your phone into the computer to try syncing/charging it that way, or just into the wall?
I tried the computer, that takes longer to get the splash screen to come up, & there is no T-mobile in Australia, plus I don't have a stock rom, and HSPL.
Try taking your battery out and making sure that none of the pins that make contact with the battery are bent or broken. It is easy to bend the pins and it can prevent charging of the battery.
Another option may be to hold the volume down button during this startup loop and see if you can get into the bootloader. It should charge in the bootloader and it may stop the looping. After charging for a while just restart and all should be well.
I have also had this and other strange things happen when the battery is depleted or very low. I try to not get below 10% anymore just in case.

I fixed the issue last night, I chucked my Battery into the Freezer, for like... more than 8 hours, woke up, and plugged my phone back together, and it charged, without booting up and restart
So all good
Obviously, your battery was terrified by what happenned to the chicken and the turkey in your freezer and decided to behave!
I really don't think it's a good idea to put a freezing cold battery into a warm handset.....that's a recipe for condensation and rust and/or water damage.
Hello everyone,
First of all my problem. My nexus 7 is dead . the battery got too low as the charger was busted and it switched off and now its not turning on. I got the OEM nexus USB cable, OEM charger and have followed almost all the troubleshooting tips on this forum and elsewhere.
Now I dont know if the problem lies in the charging point or the battery.
My question to anyone who has the idea is that, IF i charge the battery in another Nexus 7, or with an external charger, will it work?
I want to fix this( i am in Nepal) and there is no way I can get a warranty in this. So I am in DIY mode
If the battery is dead and I cant boot into the bootloader anymore, is the above idea a possibility?
Thank you

Does it do anything when you first plug it in to charge?
As in does it start to show the charging screen and power off immediately? Does it start to boot then turn off?
Was having an issue with my wife's n7 where she let it discharge all the way to dead and would not take a charge or turn back on.
There is a trick you may be able to save it without doing much at all.
Plug it in to a wall charger and immediately, or as quickly as you can, hold power and volume down to try and get into recovery mode or bootloader. Needs to be almost instant.
If you can get into recovery or bootloader select power down (in bootloader use volume keys to navigate, power button to select).
Unplug the power cord and plug it right back in. You should hopefully see the charging battery screen.
Hope this helps.

I have already tried the above method. The good news is I went to a repair shop and asked them to charge the battery externally. My nexus did start. But it seems like I damaged the USB port somehow, so it is either a POGO pin charger or have to get the port frm smwhere..hmmm
Well my D802 past away (I think) two days ago; Isn't booting into any mode whatsoever and it doesn't seem to be charging (no red led, no heat) it was on 6% battery when I last seen it working and after that I've had nothing from it; and any pointers in what to look for or any knowledge what's possibly gone wrong would be greatly appreciated
Update: Well pulled both ribbons from each side of the battery and left it for a while' plonked them back and and left it for a couple of minutes; and attempted to turn it on and the LG Logo did show for like 2 seconds and then gone back to this original state mentioned above; don't even know what this means
Battery dead? Usb port broken so it doesn't charge?

I'm unsure; I don't believe that they are broken; my phone was on or around at least 6% when it failed on me; but like I mentioned battery doesn't warm up when I've had it plugged in while but when it does go flat on battery the first couple of times it would have attempted to boot back up when I hold the power button it hasn't at all recently so I'm totally stumped
Exactly. It might have emptied to the point it doesn't have enough charge to boot up.
No heat = battery not charging.
Battery not charging = dead battery, dead port, dead charger..
Firsr try using different charger / cable. If that doesn't work, that leaves you with bad port or battery bad.
For testing port, try getting into download mode. Plug the cable to just your phone, press and hold volume up button, and then (while holding volume up) plug the cable to your computer. If you get even a hint of download mode (since your battery is probably empty, it won't stay in download mode and it will shut down), that means the port and the cable is good but battery empty.
There are other parts to it, but if none of this show any result, you should take it to the service.
This is something I would do to test it, I might be missing something. Maybe someone else can give another idea.
Recently purchased a G4; still would like a few others to weigh in on this :') wouldn't mind selling it on to fund this G4; thanks
I'm running Omni rom with eas kernel and just yesterday my phone ran out of battery, and now I can't turn it on at all. At first when I held the power button, the phone would vibrate after about 15 seconds but it wouldn't do anything. Now it doesn't vibrate or show any signs of life at all; no charging led no nothing. If anyone knows a way to get into recovery or fastboot that would be enough for me to flash a new rom but I can't even get it to fastboot or recovery. Any help would be greatly appreciated.
Thanks.
What happens when you have the charger plugged in? Is it stock charging cable and brick? Have you tried checking what happens when you plug into a computer? If it is the stock cable check the end of the cable (phone side plug) to make sure there are no burns.
You can try holding the volume-down + power.

It has been charging for hours on the stock cable and brick. There are no signs of burns anywhere, plugging it into the computer doesn't change anything either. The computer doesn't detect that it is even plugged in.
Ran out of battery? Like 1% was left? That's no good. You're never supposed to let a lithium-ion battery get that low. You might have to replace the battery. Just keep attempting to charge it and boot it up again, use different outlets, different cables and adapters, etc. This is a common issue--people are stupid and just let their phones die instead of being vigilant about charging them. And there's plenty of stories about and advice for Android phones that won't turn on after being completely drained of battery life. Google is here to help you.
Did you try what slgooding suggested?
I tried holding down the power and volume down button. I usually don't let my phone die but I went camping and left my phone in my car and I forgot to power it off I guess. Still I've never heard of this happening to anyone else.

This is a real bummer. I would suggest trying another power brick and cable. That may be your best bet. See if it has any indication it is charging.
Try a different cable to charge and press and hold that power button till it boots(2,3, 5min...) it happened to me the other day... I love my LP3 keeps me entertained...lol
I have an ASUS ZenFone Max Pro (X00T/X00TD)
It is/was discharged and powered off. When i plug it in for charging, it is cycling in start of chaging:
1. vibration
2. the icon of empty battery
3. The bootloader is unlocked... text
4. the icon of empty battery
5. empty screen
1. and then starts again from vibration
I tried to clean the phone's connector, even wiped and stracthed the connector a littlebit, and changed cable, charging source. (One cable is in the 1A charger, another cable is connected to PC.) It doesn't get better.
I tried to leave it in the cycling, i hoped it gets some power.
Does the phone charge always when connected to power, or it just start the charging process after it shows the charging animation (which i don't reach)?
I tried to step in Fastboot mode. It stays in this mode, no cycling.
Does the phone charge in fastboot mode?
I tried to step in Recovery mode.
1. vibration
2. powered by android
3. The bootloader is unlocked... text
4. powered by android
5. empty screen and turns off
In fastboot mode i tried to flash stock recovery, and also TWRP recovery. The flashing process works, but i still cannot get in recovery mode, to see something more, maybe about battery or i dont know.
Of course the phone does not turn on. The same as when i try to get in recovery mode.
1. vibration
2. powered by android
3. The bootloader is unlocked... text

I did not do anything special nowadays with the phone. Bootloader unlock and rooting was years ago, nor i did upgrade, so nothing special. I just used the phone, it discharged, and i'm in this state.
What can i do? Is it something with charging, or it has enough power after connected in fastboot mode, but the problem is something with the software?
Please help.
Was it discharged until it turned off or left more then a few weeks in a very low charge state?
Auto shutoff is about 5-6% of battery capacity.
If allowed to sit until it self discharges below 1% the battery's microprocessor will permanently disable the output to prevent a possible runaway thermal event from charging a depolarized LI cell(s).

It discharged today morning, turned off (or maybe i turned it off, i don't remember), and about one hour later i tried to charge.

Does it mean really permanently, without any possibility of get it back?
One more thing: maybe i "pressed" the buttons randomly in my pocket. Is it possible that in an unlucky situation i got into the recovery mode and pressed something away in recovery menu?
Even if discharge to the 6% cutoff you have at least a few weeks in cool temps until permanent auto shutdown.
It is permanent. If disassembled you could bypass the controller and attempt to charge.
Once the cell voltage reaches the controller threshold (if it takes a charge) it would function as before. Generally this is impractical to do.
If the cell has completely dipolarize it may not charge and will simply overheat with a potential thermal runaway if not manually disconnected.
Inspect port for debris, clean if needed.
Try a -known- good charger/wall socket and cable.
Normally phones will take a charge regardless of their power on/off state.
Otherwise the port, battery or the internal phone power control circuit may have failed.
A cable, charger, port failure are the most common causes though.
Best to use a 3 foot long cable; longer ones can cause charging issues.

So should i try to leave it in the cycle? Or better leave it in the fastboot state?
Hm. But i tried to charge in fastboot state for a few hours.
I don't understand.

Yesterday with a third charger everything was fine. And this charger was fine, last time i used it two weeks ago. I tried to charge in my car now - the same cycling of starting to charge.
Okay, so i keep trying to charge, if you don't have better ideas.
But why does not it go into recovery mode? Maybe i could inspect the things more in recovery mode.
Thank you very much for your detailed answers.
If the battery is nearly fully discharged ie >5-6% and not recieving enough current or voltage from the cable, it will not power up even to its boot menu.

But it should start to charge without cycling, and show the charging animation, right?
Edit #1: Ah, you mean, IF enough current. And if three different charger and cable was not enough for it, then probably the connector damaged. But i don't know how and why.
Edit #2: No, you mean this for booting up. But charging should start normally without the cycling.

Your first concern is getting the battery to at least 60%
That's why you use a known good wall socket, cable and charger; a process of elimination.
I've had 2 bad power cables in a row before; more bad cables, etc. doesn't help.
For the boot issues someone here will hopefully recognize your problem if it persists.

Yes, i threw out a bad cable last week. But these 3 cables were good, there is not a big chance that all of them get wrong suddenly and at the same time, i think. I would be happy, because this would be the most easy solution for my problem.
In fastboot the red/green LED is dark, even if the cable is plugged in. Is this LED controlled directly also by the charging controller? Or does not the dark LED show anything, because it controlled by software, what does not run now, while the charging still work?
Or maybe both of charging start cycling and fastboot are use power of battery, while they don't charging it, so power is only getting lower? (Although you said the opposite, as phone is charging, not matter of the power state.)
Could be a bad batch if all are the same brand.
That's why you use a >known< good cable etc.
Don't have that phone so can't say how it behaves.
If it's below 5% power it won't do anything except maybe try to boot maybe not even that. Plus each attempt drains the battery more towards that critical 1% auto disable in the Li pack.
Killing the battery won't help your cause...

Okay, i try.
Thank you very much for your help.
Is it possible to turn off the charging screen, charging vibration, screen turning on from fastboot mode? Maybe flash something on or similar?
Because then it won't use the slowly chagring power.
So the screen is active abnormally when it's charging?
Is it stuck in a boot loop?
I know zero about rooting and firmware flashing.
Eventually someone here with that knowledge will step up... be patient.

1. I plug the cable in.
2. It recognize there is power, so vibrates a littlebit, then starts to charge OR starts to start to charge - it would be in important thing to know which.
3. It shows the big battery icon at the center of the screen.
4. It notices its boot loader is unlocked, so it warns me - i can pause the phone for one minute in this step.
5. It shows the big battery icon at the center of the screen for a second.
6. But i think it feels its battery is too low, so it turns itself off, even from the charging process.
2. Then it feels the power again, so the cycle starts again and again...
In step 2., if i would know it is already charging itself, then i played with it, i pause every time for a minute, and everytime the battery gets a little more power. Because every vibrate and starting charging take a littlebit power from the battery i think.
So, for example, in every unpaused charge cycle (about 10 seconds) it gets 5 mAh, but uses 7mAh from the battery, then it get worse and worse. But if i pause it for a minute, it gets 30mAh, uses 7mAh, then every minute it gets 23mAh more, so this game eventually worths.
But, if in step 2. it does not start to charge itself, just later, after the "unlocked" text, then playing with this does not help, worse, take the battery lower and lower.
But: if i could disable the charging screen and the vibration, then it won't use the power just for showing to me it charges. And maybe the screen is the one who use the power and makes the controller feel low power from battery/cable.
Or, maybe, charging is already disabled, so no matter what i do, it does not help, and the only solution is to take apart and charge the battery directly.
I just put

Good news!
This gets the voltage of the battery:
Code:
fastboot getvar battery-voltage
It says it's 4,32 V. If i remember right, this is around a fully charged battery. So probably it charged up when i left in Fastboot state for some hours. And the cycle/loop meant not that it cannot charge, but rather it does not need to charge.
Bad news!
Then what the heck is with my phone?
Summary:
1. My phone is fully charged.
2. It does not boot into normal.
3. It does not boot into recovery, nor by hardware keys, nor by command from fastboot. I tried to flash TWRP, RedWolf and the original recovery too.
4. Fastboot mode works normally.
Believe it or not...
The solution was very stupid.
I cleaned the phone inside, especially the bottom part. Around the connectors, lot of dirt and drying moisture got in. Just enough for - probably - some short circuit.
I don't know why was it okay for fastboot mode, and not okay for recovery and normal boot.
Blackhawk, Thank you soooooo much for your help and your time. I learned a lot from you now.
Excellent.
Guess it was getting mixed signals...
