Htc one m8 - does not start - When connected to the charger, the LED lights up.

Hello,
I bought htc one m8 abroad and when I received it did not start.
I connected it to charging. Charged for several hours but still nothing. When connected to
Charging the orange LED is on all the time. I tried different chargers but it also doesn't help.
I think it can be something with a battery, but what can I do with it?

You have to unscrew the phone and measure the voltage on the battery. If it is below 3.4 V, you will not charge it with a standard charger.

There is no way to charge the battery without taking your phone apart?

No, you need to skip the charging system and give a higher current to excite the battery.

Hello,

I took my phone down, how should I check the battery voltage?

You unscrew the battery and measure with a meter

Well, the meter shows 0

What's the conclusion?

The conclusion is that a colleague rather measures something badly, if the battery was so dead, the orange LED would not light up after connecting the charger. When the battery is discharged, nothing happens first, then the LED starts blinking, after a while and after reaching the appropriate voltage (something about 3.65V), the normal charging process begins - such protection so as not to whip the battery completely.

To the author - do the chargers you used have at least 1.5A? On a 1A or weaker M8 is not able to start the charging cycle if the battery is heavily discharged and the LED is on all the time (or flashing, I don't remember exactly)

On the other hand, a lit LED can also indicate problems with the bootloader or NAND bone, but it is better to exclude charging first.

A common problem in these phones, overheating and memory corruption. It would be wise to look for a new motherboard.

I was charging with a 5V 2A charger.
An example of a meter electrode for these battery meshes and shows 0.

I bought a bargain battery that is supposed to be good. When I start the phone on this new battery the motherboard heats up but the picture is not displayed. 1507104781...288225.jpg (1.15 MB)You must be logged in to download this attachment.

Mark on the picture which eyelets you applied the meter to ?? A new or used battery does not mean that it is fully charged.

I applied to these holes.

The question was rather to which pins in this connector because there are 4 and to measure the battery voltage you need to measure two specific.
However, looking at the photo of the disc and the remains of the seals on it, I can tell you that there are already some yellow handles rummaging hard and the phone is some refurbish-folding, probably on non-original parts, which on some auction sites can be bought as 'nówki' for a few hundred zlotys from delivery time 2 months. Investing in it rather doesn't make sense.

So what won't I run it?

I was able to check this spare battery and it has 4v

I had a similar situation. I gave the battery to be replaced. After putting on a new phonik, total weakness came over him. It turned out that I came across an old battery (sold to me as a new one). After the complaint and the creation of a new phonik came to life. On this folded-up battery, only the indicator light was on, but the power consumption was practically zero.
