NO USE OF A PC TOOO….THATS simply annoying i feel as if my fingers are cut god please help me:crying::crying::crying:

God this is happening quite a lot now...

I had the same issue for quite a time, but seem to have solved it just now.
My phone only charged when the power was off. When the phone was turned on it didnt charge. So what I did was turn off the phone > let it charge for like an hour > than turn on the phone while it's loading.
Let me know if it worked. Good luck!!

[Q] Stock OneX switched itself off, now red flashing light.

I have used the search button and found many people with similar problems but I don't think any of them are the same as mine hence the question.
Please be patient with me as I'm new. :good:
My 18 month old factory stock OneX was switched off and on charge over night and in the morning the green light was on.
I took the phone off charge and switched it on, all was fine and I put it in my pocket and drove to work.
After about 5 mins I hear the low battery chime from the phone and when I take it from my pocket it has switched off and will not switch back on. I plug it in to a charger and get a red flashing light. I've searched for days and tried all the button pressing tricks, charging from mains, charging from usb and nothing has brought it back to life.
Thinking the battery had just decided it no longer wanted to be part of this world I bought a OneX+ battery and changed it over, it is still the same.
If I hold down the volume - and power buttons it will boot to the screen where it tells you it is ***locked*** and tell me not enough power to flash.
If I plug it in to the pc the HTC MTP device loads every few seconds.
Is my phone now an expensive paperweight or can it still be revived? Any help greatly appreciated.

What I understand you can go in bootloader this is ok! But it is strange that HTC MTP device loads every few seconds. Are you able to start the Android? Becouse only if you start the system you can see the MTP device in bootloader it is inposible.
Second download this unzip to folder and start the file chargeONEX.bat report back if the battery start charge. Dont worry the phone will start a lot of restart in the bootloader but will slowly charge.

I can only get in to the bootloader when connected to the mains charger, it will not go in to bootloader when connected to the laptop usb port.
I will try on a desktop pc and see what that does.
I ran the .bat file and it gave me a voltage of 477mV, this is a brand new OneX+ battery, I did try this script before I changed the battery and the old one was 536mV
Because the phone will not boot in to bootloader when plugged in to the laptop it only runs once, then the screen goes black, it is then that the MTP device loads every few seconds.

Use original cable and USB 2.0 port leave it for 20 min on the computer and after this try to go in bootloader and start the script and report back

I've just tried it in a desktop pc, an iMac and a G5 mac and it will still not go in to bootloader.
I'll leave it for 20 mins and report back.
Thank you very much for you help. :good:

After 20 mins plugged in to a G5 Mac I still have to connect it to the mains charger to start bootloader.
I then have to select Fastboot before the script will see the phone and the voltage was 501mV, it then goes black and the MTP driver tries to load again and again.
Any idea what could have caused this in the first place and why a new battery is doing the same?

Just you buy your new battery empty this is bad luck for you.
in my zip have fastboot-mac rename it to fastboot and the fastboot rename to fastboot-windows. Are you manage to start in bootloader. Are you with custom recovery. If you are with custom recovery go in recovery and try to charge the phone in recovery.
EDIT: I see you are full stock will not help with charge in recovery.
The best way will be if you start the script to charege the phone but if you cant the best way will be to charge the battery manually.

Voltage is now 520mV.
I still have to connect to the mains charger to go in to bootloader, I will leave it charging over night and see what the voltage is in the morning.

Checked again and the voltage is now 550mV.
At this rate it will take weeks to reach enough charge to switch on.
I'm not sure it will ever get to full charge, I think something else on the phone is causing the issue.

Wait to be possible to go in bootloader without charger and when you go in bootloader run the script to charge.

As my other thread has now been closed does anyone know if a lithium ion battery WILL actually recover from this voltage?

i think not, the system reads the battery voltage and 3680 mV is round about 10% of charge so 550 is way undervolted. and if i am not mistaken 4200 is about full loaded.
edit :
at least that's what i read from here

I am not sure the battery is deep discharged but have 50-50% to be good. If you have battery pack but not to connect with usb to the phone The battery pack must use the pins on the back side on your phone try to wake up the battery or manualy disconnect the battery and charge it or the chipest way is to buy new battery but mesure beffore to buy.

The battery voltage is slowly rising and is now at 562mV.
I'm still not sure this reading is correct because when you start in to fastboot or recovery you can remove the charger and the phone continues to run. Surely the phone would switch off as soon as the charger was removed if the battery was as low as .5V
Any ideas?

well it may be a bit more difficult but i would look for a way to charge the battery from another source outside the phone. something like a little project of cutting wires and connect them straight to the end of the usb cable (wall charger) ...... welll something like that ?

I'll give it a go, nothing to loose.
This is a new battery I've got in the phone now, the original one read the same voltage. Only thing I didn't do was to check the voltage of the new battery before I installed it.
I'll try charging the original battery that is sat on my desk.

I've just checked the voltage of the orignal battery that I removed from the phone fully charged and it reads 4.2V, my multi meter might not be 100% acurate as it's only a cheap one. I also checked my 65% charge HTC Desire battery and that reads 3.9V.
So it looks like the batteries are fine and the phone is seeing the wrong voltage.
Do you think this would definitely be a hardware issue?

I cant say no but indeed those voltages looks fine. It could be the circuit on the mainboard not reading correct

phone not charging ?

Hello , i dropped my phone and it seemed ok , but few hours later when i tried to charge it nothing , i tried on wall socket and pc nothing , tried samsung charger and old htc one charger also nothing

Call htc see if you can get a warranty replacement.

Let the battery die sounds like you damaged your power port on your phone is the charger you were using bent or damaged were you charging it up high like on a tall entertainment center or a bed side table

i already did , unfortunately i;m rooted and s-on , so i wont be able to go to stock completely , they told me the repaird price is around 100-200 $ depending on the problem :crying:

****ing htc asked me for about 300 $ to repair the phone without even telling me what's the problem with the phone !!!!!!!
and the phone here in my country is worth 600 - 650 $ :crying:

Note II Not starting up and not charging

Hey guys it has been a while since i used my Note 2, i had custom cyanogen rom v12 stable running it..
The phone has been off for a month.. i wanted to use it again so at first it wouldn't start, figured it would be battery ran out so plugged it for charge yet not battery symbol/logo of charging came out as it used to do.. i let it for about half an hour plugged in and tried to turn it on yet nothing happened.
i also tried download mode and recovery yet also not booting into them.
My brother has a functioning Note 2 so i thought maybe the issue is battery wise, so i switched batteries between both phones,
[the battery that was originally in my phone now in the functioning other phone... AND IT CHARGED NORMALLY]
[the battery taken from the other phone and put it into mine didn't charge!!!]
What's the problem with my phone?? how can it brick by itself after just leaving it turned off for a month.
I hope i can find a solution for it
Regards

Are you using the original Samsung cable and charger with the phone?

yeah the official cable.
I don't know why the phone failed on its own

Maybe try a 2.0 amp charger? Was the phone exposed to moisture?

Does the phone actually function properly now that the battery is charged? You could try disassembling the phone and removing the charging port and cleaning it with isopropyl alcohol and baking just the port on a cooking sheet in the oven for 5 minutes at 350 degrees. This fixed my Note II when it wouldn't charge after I dropped it in water

I also have a similar problem. I was on dn4 rom when this started my phone didn't even alow me to flash a rom so I used Odin aand failed the first time and thankfuly it worked the 2nd time. Now the phone is better than before but if I unplug it turns off and tries to reboot but stays on the note 2 logo and also if the battery is on 82% and it reboots it can jump all the way to 4%.

Problem is that the phone was left in my closet untouched for a whole month, i changed the battery and was sure it was 100% charged...
[no note 2 logo , no nothing] .. the phone is black and doesn't turn on
Its not a battery issue more than i think its the faulty rom that ruined it

The phone could only go into download mode. Also if I try to turn it on, it would only show the note 2 logo and won't go any further. Yesterday I tried an aftermarket battery with my phone and it was able to boot past the note 2 logo.

Help phone wont charge, stuck on red battery

So my zenfone 2 is rooted and today it ran out of battery. I put it on charger, there is no LED indicator lighting but ok, i thought it´s charging, so in few minutes i tried to power my device on, but i got only that low battery screen and it turn off after few seconds. I can get to this low battery screen even without charger, but it´s same. When i press power button in this low battery screen i get that bolt there, like it´s charging for a second but then it turn off. I also can´t get to recovery mode, even when i try it on that screen, it shows white battery with question mark. When i try it from turned off mobile, nothing happens. Please help me. Sorry for my bad english. Im sure that charger is OK because it works with other stuff and when i plug the mobile into pc, it´s just same, nothing. I have TWRP recovery btw.

Seems that you are having my same problem (http://forum.xda-developers.com/zenfone2/help/phone-wont-charge-tries-to-t3426130), but you can see the charging screen. Does your phone get hot while charging? Mine doesn't (so it is not charging) I bought the usb chargning module, hoping that it will arrive soon if that is the problem.
