Empty DHD not charging, not powering on, no led.

Hello people
A couple of hours ago, my phone shut down due to empty battery. I came home, plugged it in and booted it, all was fine. At about 60% I shut it off and went to have lunch, when I came back and tried to turn it on, I couldn't.
Led was orange at the time, I unplugged the power cord but the led stayed on! I removed the battery to be able to reboot it, but when I re-inserted it I still wouldn't boot.
Now no matter how I try to charge it, led stays off like it's not charging. Tried various different cables/chargers, the same. Tried to plug it to the charger without battery but no led flashed. Tried to boot without sim/sd card, still the same.
Any ideas?
My battery has never been changed (for a year now) and has had a bunch of full drains. Could this be a dead battery? :/

Well seems the phone is fried... I tried two more official batteries and no go...

Sorry to hear it. I thought that at first when I read your thread but I thought because I am not the most experienced person here, there might be some kind of fix.
HTC will most likely if not certainly replace this handset for you, seeing as it just happened out of the blue.

Well I certainly hope so, problem is I suspect it's an import (from another European country) and local HTC service generally does not do well with European imports.
Anyway I'll give it a try, meanwhile I'm getting a sensation soon

I have a similar problem.
I'm lucky that my girlfriend has the same handset as I do, the I could compare the phone abnormal behavior tho that of her properly working phone.
The first thing I've noticed, after a while when the charger was attached, was that the phone is very hot and that the battery keeps draining out in a surprisingly high rate.
After a while I've noticed that even when the phone is turned off it wont recharge. Sometimes the Orange LED is on when recharging while it is off, and the LED stays on for a few seconds after removing the charger, as if it was still charging. Note that the affects of connecting the charger to the phone, are mainly the ones listed below (not necessarily altogether)
* The phone indicates as if it recharges.
* Going to an infinite loop of rebooting and crashing.
* Getting hot when power supply is plugged, or at any time when the phone is turned on.
Ultimately the battery was empty, and the only way I had to keep using the phone (mostly to diagnose the symptoms listed here) was to swap the battery with the one of my girlfriend's device, and charge my battery in her device while using her's. That's the place to mention that the battery works just fine and that the phone is draining any battery, no matter what.
I took it apart to have a closer look at the source of all of the heat emitted while the phone is turned on, and it seem to come from the motherboard itself.
That's all I have.
The worst thing is that a friend of mine who helped me opening it up broke the pcb of the volume keys. Now I checked and It turns out that that pcb is actually part of the flex cable, which sort of extension of the motherboard and is mainly the second most important piece of hardware of all the phone parts (not that there are so many). If I would be able to expose the conductors inside the flat cable I might be able to solder an alternative volume pad I'll make out of old some miniature switches I have. The cable is very thin. any Ideas of how to expose the relevant conductors without ripping the cable apart?

Just a (late) update:
It's been almost two years, I had given the phone to a close friend of mine after a couple of weeks since writing the first post, just in case he could resurrect it, nothing.
Then, a couple of months down the road, the phone suddenly woke up! He tried to connect it with the charger, after months of not being able to charge or boot it up and somehow it worked. And it has been working flawlessly ever since.
I just got it back to give to my girlfriend until her sensation is fixed, flashing Viper now
In case something like this happens to any of you, don't give up!

[Q] Phone stopped charging after a a few odd beeps

A few hours ago my phone started emitting beeps as if some notification was turned on (I have all such off). I have not paid much attention, as the beeps eventually stopped (!!), except for when noticing, a while later, that the phone - albeit plugged in and with the battery indicator showing "charging" - the percentage was decreasing. I watched it for a while, and the batter was discharging while plugged in. Did the followings:
- replaced the battery with a new/charged one (my spare) - same behavior
- replaced the cable with the original samsung - still the same problem
- tried wall outlet charge, laptop charge (via USB), etc - same problem
The questions for those having experienced such:
- would the beeps be indicative of a problem, or just coincidental???
- the phone is definitely the culprit here - the question is if there is something that could be done for some sort of cleanup of the port, or improving the connection (seem to recall some such from a site - maybe this, maybe another forum - could not find the article by searching), or further tests I could carry out, before I take the phone into the repair shop (which I am not sure if there is such in my area)
TIA,
Stefan

can your phone charge with the phone off? Turn off the phone and then plug it in, do you see a big battery icon charging? Also is your phone rooted?

Upon turning the phone off and first plugging it in, it depicts a grey battery with a non-spinning wheel in the center. After approx. 10sec the screens starts showing a semi-filled with green battery, with a scrolling bar of dots underneath it (active this time, unlike the wheel described before).
I am sure that everyone knows what I am talking about, having seen it many times before, even if my description is not that good. The issue is that I have never paid attention to this part - mostly because I almost never had the phone plugged into power and not immediately turned on.
Observation after doing the above: after having left the phone off for almost an hour, the battery charge decreased (84% -> 80%) while the phone was plugged in.
NOTE: When the charge was 100%, by using a battery I charged with an external samsung charger, I also re-calibrated the battery using the app (phone is rooted, but always using the stock ROM). Just FYI - if that matters.
Thanks for any [ongoing] assistance.

ok if your phone was off and plugged in, and was still losing charge then I'm not sure what to do, sorry, hopefully someone else who has experienced and solved this can help you out.
my issue was similar to you where i couldn't charge my phone while it was on, i could only do it while it was off...it was a software issue, so i flashed the stock ROM, started from scratch and everything was fine from then on.
if you havent already, make a back up of all your important data (msgs, apps, etc.) download a stock rom (http://forum.xda-developers.com/showthread.php?t=2276645) and flash it, maybe that might solve the issue

The beeps may have been the phone detecting the charger on then off multiple times. Check the charge port on the phone for any breaks or debris.
Otherwise I dont know what to tell you aside from try another cable and charger. Sorry.

Damn ! I had this error too but it would charge but so SLOW! It was on a ROM/KERNEL that i've flashed , I cant remember wich one. Try charge your battery in Recovery ( this was my solution )

[Q] USB port damage? Causing it to think it is always charging

Okay, this is a weird one that I researched and researched on the web. I think the problem is somehow related to the USB port. It would seem that my handset thinks it is always charging. I should qualify that statement by saying that with the handset unplugged from the charger and checking the SETTINGS > BATTERY stats it says "0 seconds on the battery" presumably meaning that the handset thinks it has a freshly charged battery and no time has expired since removal of the charger. However, it knows it isn't charging because it also says "89% Not charging". The other weird thing is the handset doesn't screen timeout when unplugged from the charger. That is, I have to hit the lock button to turn the screen off otherwise the 15 second delay doesn't work. I've also checked the developer settings to verify it isn't set to force the screen to stay on. However, the 15 second screen timeout delay works perfectly when the handset is plugged into the charger. After 15 seconds the screen shuts off and the red LED charging light comes on. Lastly, with the handset sitting idle with the screen black if I receive a phone call or text message but just leave the handset sitting there the screen lights up but it never times out after 15 seconds.
Any ideas if this is a USB port problem. I know it sounds like a firmware problem but I've checked just about everything you can think of. I've gone as far as to root my phone, backup all my stuff, then re-flash JellyBean. Speaking of USB port. Has anyone changed one out on a S2 Epic Touch 4G? I know that other S2's have a USB flex cable assembly but I can't seem to find one for this particular handset.

I had a similar issue a while back. All I did was clean out the gunk built up in the usb port with a wooden toothpick and the issue any away

I had tried the toothpick trick that you and others had recommended. In fact it did make a positive difference but I still noticed there were still some strange things going on. I went back a second time but this time with a sewing needle and some magnifier glasses and picked it clean of lint and other junk. Of course with was done with the battery uninstalled. I think I'm back and up and running. We'll see if any of the problems come back. Thanks!

My aunt has a device with the exact same problem. It goes doo-doop like you connected the charger. And you can't turn it off ever because it gets on again. Did you fix it?

Using the toothpick/needle trick went a long way towards getting it to behave properly. Like you said, it was doing the "do-doop" thing intermittently and sometimes it would go into and out of charging mode so fast that unless you were astute you wouldn't have realized that what it did. To figure it out I went into SETTING > BATTERY and observed that the "discharge time" on the battery would typically stay at 3 seconds which told me the phone thought it had been plug into the charger.
For the last two days it would seem that I have fixed the problem. After you carefully clean out the USB port of lint and junk with a toothpick and a magnifying glass or readers you may also want to consider getting a can of compressed air to blast it clean. I'm talking about the kind of compressed air sold at Walmart or Office Depot that is used to clean electronic equipment to blast the dust away.
Let us know if you get it fixed!

I don't know if cleaning the USB port had an effect on battery time but I'm getting relatively awesome battery performance like I've never seen before. After 12 hours and very light use the cell phone still has 81% battery left on it. It used to be sitting at around 30% by this time in the day.

think im having this problem. thinking its a damaged usb port. old battery everytime you stick the battery in or plug it in it thinks its charging. new battery i just ordered does the same too. its still charging so ill see what happens after but i say charging port probably?

I went through the same exact thing...ordered a new battery thinking the original battery was at the end of its life and causing the phone to behave strangely. With the new battery in place the craziness continued. I was thinking the micro USB was damaged and needed to be replace which BTW isn't an easy thing to change out like some of the other Galaxy phones because the S2 uses surface mount solder connections. You'll need very good eyesight and professional soldier skills to do it right without effing it up. Luckily, doing an extensive cleaning of the USB port fixed the problem. You wouldn't think lint would be conductive enough to cause a problem but alas, it does. Use a toothpick and compressed computer cleaner air with the battery removed when you clean it.

I'll have to try with the toothpick later. It's weird when you go into setting and look at battery it knows when it's on charge and when not on charge. But soon as you put a battery in, it turns on by its self but to the charging screen and can't be turned on unless both charger and battery are in.
Will the battery percentage read accurate still I wonder?

Yup, that is exactly what I saw when I was having the problem. Basically what that screen shot is telling me is 13 seconds ago your cell phone made the "doo-doop" sound as a temporary short within the USB port fooled the cell phone into thinking it had the charger plugged in but just as fast as it thought the charger was plugged in the temporary short went away. In fact the "short" may have come and gone so fast as make it so that "doo-doop" isn't even heard. The key here in recognizing the problem is that while your charge may have been unplugged for hours you'll note the number of seconds that have gone by since the cell phone thought it was charging will be somewhere well under 60 seconds or at least that is what I experienced. I have every confidence that you have the same exact problem and you just need to thoroughly clean that USB port of every speck of lint and dust. Also, make sure your charger USB is clean and lastly make sure none of the pins on the USB connectors is bent and that that middle portion on the cell phone USB is right in the middle and not bent up or down in any fashion.

How did that happen?
BTW, don't forget...if the phone doesn't seem to want to power up hold the VOLUME UP and the POWER buttons at the same time for 15 seconds until you get the reboot option.

I'm in the same boat now [emoji22] Just happened a couple nights ago... Phone is plugged in but not charging. Not that big a deal, as I just got some spare batteries and external chargers. But now I've got to be super-cautious when flashing stuff, as I can't just Odin back without working USB

That's what I'm stuck doing now. I'm not gonna be switching roms anymore lol. Had to buy a universal charger for the battery

I had this issue with mine as well. At first it seemed to be the recovery but I reverted to stock unroot and it still happened sometimes shine blue to make it think it was completely charged I know this phone had a lot of hardware issues. And then I took it apart cleaned it and what not. It still happened. So after some time it just stop happening and functioned normally. I am unsure what the problem was or why it happened. The whole time I really couldn't charge my phone at all unless it was by computer only

G7 will only charge when powered off

I seem to be having the same issue as found on this thread, can't find anything here though.

Anyone else have the same issue and found a fix? Guessing this might have to go back to lg.
Thanks!

I started getting this issue yesterday a day after I got a software monthly update for Nov. I normally shut the phone off to charge but sometimes leave it on. When plugged into something it doesnt seem to detect its plugged in. I even swapped cables to a slower charger and same thing. It doesnt see it.
When I fully charged it off, It beeps the battery and does a circle hue randomly by the home button but than detected the connection to pc. I ignored it and started up again but without the beeping, just wont charge when on. There is no dirt or anything in the unit,. I have not moved any-wires, they have been sitting in the same spot on the counter since day 1. I'm gonna try a factor reset if it keeps happening a day or 2 from now.

Same problem here, it was behaving strangely few days ago (charging problem right away but worked in the end so let it go) and now it charges only when off or if plugged within 30 seconds after turning on and only on normal charge speed (not quick charge). Tried to wipe apps and everything, did the facrory reset 2 times but still nothing.

I have similar issues with charging my g7, first give me notification of moisture detected on USB port, then can't charge normally need to plug a few times and sometimes get slow charging, i was thinking have faulty USB port, and have poor battery life.
Then I turn off and put the cable and charges normally and realized that it's software issue.
I flash the ULM10i firmware and now everything work flawless the USB port charges when it's turn on and have very good battery life now.

As an update, I called LG and they basically stated that it sounds like a software issue and to send the phone in. I declined hoping to get another update that would fix it.
I have yet to get one from T-mobile. Long story short, it corrected itself and now charges off or on and no longer does the beeping. Whatever it was, was a bug that temporary for me.

same problem here; no moisture errors, aleatory starts charging when it's on, poor battery life; mainly starts charging with the phone off

problem solved! I've forced LG BRIDGE to reflash the ROM and voilà, all working like a charm. Just download from lge.com, install LG BRIDGE, under "software update" ... "update error recovery" and it will download and reflash the working ROM.

HELP! Can't charge Galaxy Tab S 10.5

I've been having all kinds of trouble getting my tablet to charge. It's acting really weird. Over the last couple of days, I will turn the tablet on and it will say 80% charged (after being plugged in all night). Then, with it still plugged in, it will drain down to 15% in about 30 minutes. Why would it drain so fast (if at all?) when it's plugged in? It's also been taking hours for it to charge once it hits that 15% and I don't use it.
At first, I discovered my charging cable was to blame. I'd plug it in, but the tablet wouldn't detect it was connected unless I pulled on the wires just right for them to make contact. Apparently there was a broken wire inside the plug of the cable. So I replaced it with a new cable. Everything seemed to be working good then, and was actually getting proper charges again. Now though, it doesn't seem to want to work.
I was using the tablet yesterday to check my email. It had been plugged in all day and not being used. It said it was at 100%. After about 10 minutes though, the tablet shut off saying "battery low". When I try to turn it back on, I get the battery indicator showing it's at 0%. So I left it plugged in the rest of the day and over night. I just went to turn it on about an hour ago, and it's still sitting at 0%!
I thought maybe the cable was bad again, so I found another charger and tried that. It does the same thing the other cable does.. It stays off until I plug in the cable. Then, as soon as it's in, the tablet "wakes up" and displays the battery indicator. Like, it detects a power source has been plugged in. But no matter what I do, and how long I keep it plugged in, it stays at 0%. I can force the tablet to turn on by holding the power button. It goes through the boot animation prior to loading the screen. Then, in about 5 seconds, it turns itself off again.
I don't think the battery is truly at 0%. If it were, how would it be able to boot up without even a cable plugged in? I really don't know what to do now. I've rooted it, so I can't send it in to Samsung for repair. I don't even think the warranty would still be good at this point anyway. The tablet is at least 3 years old (based on when I joined this site looking for root help). And I think it was 2-3 years older than that before I bought it. Is there anything I can do?

I can't wait anymore. So frustrating to own something that's worked great then all of a sudden decide to no want to even power on anymore. I've spent all day trying to get it to charge with other cables. I've tried chargers, I've tried just straight cables. Plugging into the wall, plugging into the computer, plugging into the USB port in the car. Nothing works. So I hopped over to Amazon to just order a new tablet. I can afford it, not big deal there. But then I saw a ribbon cable used to replace the USB port on the tablet. Maybe the port is bad? Lots of "highly recommended" reviews. I went ahead and ordered one. It was less than $7. If it doesn't work, I still have the money to go forward with buying a new tablet. If it does, money saved! I went ahead and bought the "customers also buy" kit, with a replacement battery (just in case it's not the port), and a set of tools. If the cable is all I need, I'll have a spare battery. If the battery is all I need, I'll have a spare ribbon. If it still doesn't work, I'll go back to my original plan.
Just kinda bummed this is where I have to go now. Why would it suddenly just stop altogether like that? Is it because I keep it plugged in 95% of the time? Should I keep it unplugged till it's drained then charge it and unplug it again right away? I used to have to do that with an old cell phone. This is my first tablet so I dunno. If I end up needing to replace the whole thing, it'd be nice to know from experienced users what the best way to do it is, and what, if anything, I can do to prevent it happening again.

I'd suspect the battery is kaput.
It's not a good idea to keep the battery on permanent charge, there's no need. Let it cycle normally.

Well, all told this was an educating experience. I got the battery first. It came about 40% charged. Once it was installed I used TWRP to create a system backup and downloaded it to my computer. Then I left it plugged in overnight. The next day it was down to 30%. So the "charging" indicator on the screen was just a bunch of lies. I got the replacement charging port a day later and installed it. I didn't do anything else with the tablet, just left it turned off and the charging cable plugged in. It said it was charging, but again, after about 12 hours of charging overnight, the following morning it was down to 18%. So I'm returning both the battery and the port. They may still be working fine, and the problem is elsewhere in the tablet. I accidentally broke the little metal connectors over the power button (it's a contact sensor, and the connectors sit on top and complete the circuit when the button is pressed) when I took the back off to replace the parts. I also cracked my screen, although I think it's just the protector I put on it. I'm not sure what else to try at this point. The tablet is essentially a paperweight now. I can turn it on and watch the battery slowly drain to 0%, but I'll never get any more use out of it. So I decided to do a system wipe prior to putting it away for some future project to try and rescue it. Now it's stuck with the "Teamwin" screen flashing at me. I give up. I looked at Amazon to see if I could just buy another one, but they don't have any "new" left. They're all refurbished or "slightly used" from 3rd parties. I looked at other tablets, and bought a new Samsung Galaxy Tab S5E. It looks like it has the best reviews and marks. The only issue would be the wifi, but it seems to be a hit or miss with people. Some people say it's a problem, others say they don't even have a problem. So.. <shrug> I'll see how it works for me.
