[Q] M8 No longer charging. Any options? - Verizon HTC One (M8)

I bought the M8 six months ago and loved it to death. Nothing was wrong with the phone.
Suddenly the battery quit taking a charge from any charger plugged into it. I went to Verizon to get it resolved but the only option was to send it to a hokey cell phone repair type place who wouldn't give me a quote on the cost to fix it.
I just purchased a new charger port (the board that includes the audio out port and ribbon cable) that will be shipped next week. The phone is already apart and the offending part removed.
Figuring it could be some solder joints that got yanked loose at some point and I was already going to replace the part, I baked the old part at 385 F for 6 minutes. No luck.
Are there any other options for charging my battery? I'm talking physically charging the battery directly. Is this possible? Are there any other options for me to charge this brick until I get my replacement part? Also, is it possible the charger port isn't even my issue?
EDIT: I figure it's important to know this: The phone is completely dead. I can't get anything at all to show on the screen. No charging light. Power+Volume up for any length of time does nothing, as does power+volume up+volume down.

Brought it to Verizon a week ago. No warranty through them because of case scratches. Do you think HTC would be any different?

Did it just flat out die one day or did you try charging it while it was still only to notice it not actually charging. If it's totally ran down and you fixed the port, it could take up to twenty minutes until you see the charge light.

I was having a couple issues a little while back where it would take significant persuasion to get the thing to charge. That's why I figure it's the port. At some point the phone died and since then it hasn't charged. I left it on the charger for over 5 hours hoping to get something. Nope. I haven't replaced the port yet, the new port comes next week. If it's the port I'm all good. In the mean time, I want to know if there's any way I could get this existing junk port to work somehow.
Been without a phone for a week now. Didn't realize how much I needed it until it died.

I took a good look at the teardown of this phone the other day. Did you repeat the ribbon cable once or twice? Look inside for foreign matter? I would recommend against tinkering until you have the new part. The new part is your most logical approach and will be easy to test.

Do you mean repeat the cable as in unlatch it, remove it, and relatch it? I did that several times in the process of trying to get the board to work. And do you mean inside as in the inside of where the ribbon cable attaches? I haven't done that but I'll be very surprised if there's anything in there. The port itself is completely clean, not bent, no corrosion.
I'm pretty good with soldering and the like because I did micro-pcb assembling for work a while back and other projects. I'm not scared of tearing this board apart (the charger port board, that is).
Oh, and before I forget, what is that aux clip on the left for? I have two aux cables that attach to my charger port board but on my replacement there's only one. I checked part numbers for my phone but everything I've found says it's compatible.

Oh, nuts. Of course it's something major. Here, I'll link the page without hyperlinking it:

Just by inspection all the brass pieces (if they are brass) could be salvaged and resoldered to the board I bought. The solder pads are all there, they just don't have the part on them.

Here's one from Ali..... They are normally fast to ship...

I would probably verify that charge works using the cable you have coming. Then move that connector over. That way you verify the port issue first.

You could remove the cable and plug it into a charger... Then see if you find 5volts of DC on ribbon end. See if power is making in through the cable.

Gotcha, I'll do that. The ribbon has many cables through it. I'm assuming they alternate polarities and I can just pick one cable in the ribbon and test it against another?

[Q] Dropped gTab! Not Charging!

I am quite bummed at this situation. If I can't manage to fix it I will be buying a new one (though I might wait for a price drop.) I've had it for over 30 days so no replacement under warranty. In the meantime does anybody have any thoughts on how I might fix it?

Well how good are you at taking apart things? The back cover is held on by 4 screws that hide under the little rubber covers in each corner. Then you need to release the clips that help hold the back on with a guitar pick, old credit card, something like that. You may have jarred a connection loose inside, or even broken one.
Does it power on at all (red light on front when plugged in), but just doesn't charge the battery?

It powers on fine, and has about 70% charge. I've seen it drop so I know it is not getting a charge (i was hoping it was just the light.)

There's a thread here about disassembling the Gtab, with pics. It sounds like hopefully a connector. Maybe look at the pics, to see how the battery, etc. is connected or ask on that thread.

You're gonna have to re-solder the power connector. There were a few incidents of this mentioned elsewhere.

My Touchstone charging case hack [UPDATE: Not Recommended]

IMPORTANT UPDATE: After a month of running this, I have concluded that the Palm components are not compatible with this phone. I was getting frequent reboots and eventually some instability of my phone. A couple of times my phone went temporarily dead and would not revive until I plugged it into the wall. I'm leaving this up in case others want to try it, but be aware you may be asking for trouble.
Lots of people have hacked the Palm Touchstone inductive charging setup for their phones, but I've seen nothing specific for the One XL. I used this thread by android94301 to get started. It's good for background and applies for the One X up until he starts putting it in the SIII back. Go and read the OP, as I won't repeat much of it.
I used the charging case approach because I did not want to open up my phone or make any permanent modifications to it. I wanted something simple, removable, and non-destructive. I used a TPU case because a) it's flexible enough to accomodate the charging coil and b) it's what I had. Plenty of other cases ought to work.
I would not advise attempting this project unless you're pretty handy with a soldering iron. You have to solder all the parts together or your won't get a good connection, and it's hard enough even then.
The Touchstone base will not work with a phone charging cord or the USB port in your computer because it needs more than 0.5A. It will, however, work with a tablet charger--at least it worked with my Nexus 7 charger--so if you've got a spare, you can save a few bucks and use that.
What you'll need:
-a charging back from a Pre or Pixi--I used the Pixi; be aware the Pre coil has the polarity reversed.
-a soldering iron
-some thin wire. I used two different colors to keep the polarity straight.
-some method of keeping the leads in contact with the pogo connectors.
-a multimeter to check your work. You'll want to repeatedly check whether you're getting 5V from the charging coil, because it needs to be aligned correctly with the base.
-a utility knife, wire cutters, and small needle nosed pliers
1. Start by carefully removing the coil assembly from the back. Peel the tape off, and keep the silver tape--you'll need it later. Using a sharp knife, very carefully pry the coil up from the adhesive. Pry out the four metal discs (be careful here--the Pixi back is quite flimsy, and I ended up punching the precision screwdriver I was using through the back and into my finger).
2. Once you've got everything free, place the case on the base and arrange the coil and discs so everything is in position. Check voltage with your multimeter. (Note: I ended up reversing the arrangement of the coil in the final version--it doesn't make a difference which way it goes.)

}
3. On the copper tape attached to the coil, you'll see two square contacts. Solder a wire to each one. On the Pixi, the contact at the end is + and the other one is -. Note that in this photo, red is + and black is -.
4. This should take you 10 minutes, tops. Now comes the tough part. By far the hardest part of this hack was getting a good connection with the pogo contacts. I came up with a workable approach, but you may want to try something else. Whatever it is, it needs to keep pressure on the leads to keep them in contact. Simply taping the leads to the contacts does not work, however.
What you see here is a piece of circuit board cut from an old 2.5" SATA hard drive adapter. I used it to fabricate a little pogo pin board by removing all but two of the connecters with my soldering iron. I pushed the remaining two through the board a bit further after melting the solder, then soldered the leads to the pins. You may note that the wires are reversed from the previous photo--this is because I accidentally soldered them in the wrong arrangement on the board, and immediately after this realization, the black wire broke off the coil. So I just unsoldered the red one and reattached them so the board would get the correct polarity. Again, check your work throughout this process to be sure you're getting a charge at the final connection.
5. Tape or hot glue everything into place. I taped my pogo board directly onto my phone just to make it easier.
This isn't quite the final product. I'm going to move it to an opaque case, and I'm going to try shaving down the pins on the pogo board because it's a bit thicker than I'd like. Still, it all works.

Hmm, that sucks.
That might explain why no one replied lol.
I've done the same thing ( buy a touchstone and a pre back)
I've gotten to the stage that the circuit board is removed from the phone back and I've soldered on 2 wires.
I'm having real difficulty trying to get a reliable connection to the pogo pins as they are so small and in a stupid place!
Would really like to see your photos to give me some inspiration but I can't. Any ideas?

The Touchstone base. It's actually quite small. Maybe 2" round and 1" high. Not much bigger than the coil in the first pic.
Someone who knows what there doing should make some of these and sell em.

It wouldn't be that hard. You can get pins that are designed for pogo contacts for next to nothing, and building a little contact board for them wouldn't be complicated. I just went with what I had because I didn't feel like waiting on another parts order.
Update:
After a week or so on this thing, I'm mostly happy but I have noticed one interesting thing. It charges fine up to around 90-05%, but it simply won't charge to full. Once it gets over 90% or so, it starts waking up every few minutes but never gets to 100%.
I think what may be going on is that the chip controlling the voltage from the induction coil is not completely optimized for this phone (which should hardly be surprising). So when it goes to trickle charge as it gets close to being full, the chip gets confused and stops the current, then kicks it back on when the phone keeps drawing on it. This causes the phone to wake up as the charges goes off and back on again. This cycle keeps repeating, thus preventing it from ever reaching full charge.
It's not a big deal for me as the difference between 100% and 95% is not that significant. Still, if you like everything to work perfectly, this may not be the mod for you.

Do you see the phone flipping between charging and not charging? I wonder if that's what I was seeing when I tried it on my phone. I was always nearly fully charged. I wasn't sure if it was my phone being picky or if there was something wrong with the charger. Same thing happens in my car charger too.

I haven't watched it closely enough. It just seems to wake up repeatedly while sitting next to me on my desk.
Okay no worries, I'll try it again when the battery is a bit lower and see if it responds.
So no dice on the low battery test. I guess my phone is just picky
I tried this afternoon. In fact, it rebooted when I left it on the battery screen to see what would happen. I've had this happen more than once, and I'm starting to suspect the mod is responsible. It only happens when the phone gets up to 95% or so.
I would be careful about that car charger, if it seems to be inducing issues. At least two people I know of have had their phones hard brick while on their car charger.
Ok i purchased all the necessary items, but my Coil is different from the one you have in the pics.
take a look,
so i am a bit confused.

Is that a Pre back? Looks like the power contacts are those two metal squares on the right.
Hi i'm sorry but it looks like the images are broken again. Can you maybe email them to me/pm or something? Really want to try this out...
This seems fairly straightforward
However, did you consider putting the coil in the actual One XL body? I have no idea how thick the coil and/or controlboard is, so I have no idea if that would even fit remotely.
It would also solve the pogopin problem, as there are some pads you can solder to (where the pogopin board is) inside the casing.
I just hate cases

[Q] Help. My tf300 is dead

1. I dropped the tablet from approximately 50cm above a hard surface.
2. Initially, I thought it was no big deal, so I proceed to try turning it on.
3. Something was odd; the tablet did not boot at all. It's NOT stuck on Asus logo. All I can see was black screen, completely unresponsive.
4. So I tried to hold power for 30sec, reset, hold reset for 30sec... nothing worked. :crying:
5. I figured, 'something must have gone wrong with the hardware when it dropped'.
6. Thus, I opened the tablet & carefully tried to find out what went wrong. (And I really hope I didn't break it even more in the process...)
7. And here I am stuck with no more idea.
WHAT I FOUND OUT:
LED indicator flashes twice when I press power or when I connect charger. Edit: It only flashes twice if I have charger connected. Nothing happens if it's disconnected from charger.
PC does not recognize tf300.
I have no warranty.
Please help me. Thank you!

Thank you, I fixed it!
I simply disconnected the battery connector and reconnected it, and everything magically started working again :victory:
I seem to have the same issue

Hi guys, I am having a similar problem. My device won't turn on unless the charger is connected. The battery display says 94% but if I unplug it, it immediately shuts off. It is like using a laptop with no battery connected, being powered by the charger only. I think it might be the same case as the OP here?
Well, looking at the photo tutorial and the video, I am still unsure about the exact location of the battery connector. Could you point it out more clearly for me? My tablet is out of warranty and I'd like to give it a shot at DIY, but taking the least possible risks.
Thanks!!

It's located underneath the copper shield. You need to lift it off to see. The connector is visible in plain sight. Just follow the wires coming out of the battery. But if you're still under warranty and don't want to break the seal, you can resort to Asus customer service.

Thanks, I will take a look at it tonight as it is just outside the warranty period
Hopefully this will solve the problem. I will post back when I try.

Well I tried disconnecting and re-connecting the battery connector, but it didn't work. To make things worth, the touch screen is no longer working. I am getting desperate... Can you point me in the right direction for, at least, getting the screen to work again?

Well, don't panic just yet. Try to remember if you'd done anything (flashing, loading or playing around with software) or anything had happened (tab drop etc...) before the tab started acting up. AFAIK, the TS board doesn't fail that often, but is fragile and thus prone to physical damage, especially the connectors and cables. The least movement in the wrong direction would wreck it. Pushing the cables in at the wrong angle would bend the pins beyond repair, to give you an idea. And you should've disconnected the battery or turned the service mode switch off before even touching anything.
At this point, my guess is either the battery is dead (not charging)*, or some weird software is screwing up the reading. Apparently, the main circuitry is intact since you can turn the tab on with the charger attached. If you can access recovery, and assuming you have CWM (TWRP requires touch), you can try wiping the battery stats.
Regarding the touch screen, there are a few possibilities. Check the surface of the mainboard if there's anything that's burned. Check the cables to make sure you did not displace any of them while pulling or pushing the battery connector. If you reconnect the cable or boards make they are seated correctly. Don't pull on the amber ribbons coming out of the digitizer. Last time I checked, the green part pasted to the face of the touchscreen can detach with the force you use to peel a protective screen off your tab. I kid you not. Above all, do not force a cable in, do not snap them in. They should slide in easy if you do it at the right angle. If nothing is damaged, I wouldn't worry too much about it now.
If you have access to a keyboard, you can go into the /etc/firmware/touch/ folder to see what's in there. This only shows the correct info if you're on stock rom. Then note the model of the touchscreen printed on the white sticker on the ribbons.
Again, turn the service switch off first.
* not charging could be caused by the battery itself or the chip controlling it on the mainboard. But we want to examine the obvious first.
wow this trend really old.
...just rediscovered my old asus transformer n upgraded it android 7 and gave it to my niece...
lonq story short she dropped it. and now the device dead. I opened it and reconnected the battery and still the screen looks dead.
when I connect it to the laptop, windows detects it and even shows it's charging
... did I miss something or? everything looked connected when I opened it

USB Power Connection

Has anyone had any issues with the connectivity of the USB port when trying to charge? Mine doesn't always charge; I have to find the right position for it to make correct contact (it doesn't seem loose either). I've tried different cables and I applied a couple bursts of contact cleaner to it to see if that would help as well--no go though. Any ideas?
It's breaking. It's difficult to fix. You could see if someone will try to fix it for you but they gotta be pretty good. Otherwise invest in an external battery charger.

Bummer... I'll try and look for some kind of guide on the net. I've fixed other electronic devices in the past, so I'll give this a whirl... Thanks for the reply!
Godspeed! What happened to mine was the traces broke off from the motherboard so I had to re-attach the connector. The connector itself was still in good shape though. It was quite a challenge.

Are you seeing that the battery is intermittently charging when plugged up? My wife's phone is having issues and I have isolated it to the most likely culprit being the USB port, though the port is not lose and I have cleaned it out. All I can figure is that it has bad connections with the motherboard. Phone works fine if I externally charge the battery and insert. Wanted to see if you were seeing the same sort of things. At this point, for $139.95 and free shipping, I ordered a Blaze S 4G from Amazon for her, and will likely give the S 4G to my daughter to play with.

Yes, it'll go in and out of the charging state; but when I put it in the "right" position it'll go back to charging. I opened it up to see what the deal was and everything seems fine. However, I did get a chance to compare it to a "working" one and it seems the metal port housing is a little bit out of whack. So when I get some time I'm gonna see if I can get it back to normal--the metal seems a little flimsy.
Here's a really good guide that I used to take it apart: http://www.youtube.com/watch?v=qMOdkBadlJU

Mine is doing the samething, 5 use an external charger with two batteries. I also use a different phone to upload roms, or anything else to the micro SD Card. Seems to work just fine.
Just got mine back from Josh over at mobiletechvideo. 35 bucks to change port. I couldn't buy a decent soldering iron and the part for that price.
Glad you got it fixed!
Another problem may be the USB cable itself -- My beloved OEM Samsung 2-meter cable doesn't work reliably any more, it needs to be "drooping" a bit to make contact (in any device).

Before I waste any money - What do y'all think? Battery, or worse?.. YiKES !!

So, yesterday, I'm just lounging on the couch, readin' on my OG Nexus 5 (from 2013, mind you). &, BAM !! Just turns off (with about 40% battery). So, I'm thinkin', "Ok. I'll just force a reboot..." NOTHING !! So, I plug it in... NOTHING !! I'm talkin' NO LEDs, no charging indicator, no NOTHIN' !! Can't access recovery or bootloader. I believe it to be a hardware issue, whether battery or some board, idk. So, what do you all think? Replace the battery? And, If it is dead, I'm out of luck !! Because, I have a good amount of research that I hadn't backed up yet. Btw, I'm no slouch, so I've tried every button combo, etc. Neither, do I believe it to be an internal power button issue.
Running rooted stock 6.0.1 MMB29K, stock recovery, franco.Kernel r79, SuperSU 2.66-BETA
Thanks !!
Mod Edit: please don't bypass swear filters
I suggest charging the phone using the original cable and charger that came with the phone. Leave it on the charger for about an hour to see what happens.
Yes, it could be the battery but it could also be something else. I assume you don't have another Nexus 5 to test it with.
Try to disconnect and reconnect the battery's wire. I had a similar problem and it was solved by doing so .

I've tried this, and unresponsive. And, you have assumed correctly. lol Also, I've only used the OEM cable & charger (aside from the occasional alternatives out & about i.e. friend's charger, g/f's, etc.).

By this, do you mean the long L-shaped one? Or, the smaller connection at the top of the battery? Because, I had disconnected & reconnected the ribbon, but never removed the battery, as I lack that li'l blue tool in the iFixit video.
Well, the battery will be the cheapest unless you can quickly score a used N5 with a damaged screen and working internals.

The small connector not the long L shaped. I think the L shaped is for the speaker and some other components in the bottom of the phone and not related to the battery.
You don't need the blue tool to remove the battery. Just heat the battery with a hair dryer to soften the adhesive. Then, take a a flat blade and gently slide it between the battery and frame. Slide and gently pry the battery away from the frame. I have done this several times on N5s and never had a problem.

Ok. So, I had gone ahead and disconnected & reconnected the battery connector to no avail. :\ (Why do bad things happen to kinda sorta, in a way relatively good people like myself?.. smh) Any other advice?..
So, I'd decided to stop being a cheap BASTARD and ordered a "Genuine OEM Google Nexus 5 LG D820 D821 2300mAh Battery BL-T9 3.8V 8.74Wh" on amazon, sold by YDT Parts for $6.49 (Free Shipping from California) if anyone else is interested. I'll post results after installation, just-in-case anyway else finds themselves in my predicament...
That price is really good for a genuine oem battery compared to prices from etradesupply.

I KNOW, RIGHT !? Hopefully, all that I have is a dead battery. Guess I'll see soon enough. Now, if only there were a way to get a fingerprint reader on this device, I wouldn't update till the N5's no longer updated. (What's the official term for that, anyway? Not EoL, is it?..)
Let's hope it is genuine. I bought one from Aliexpress that looked just like an original but people said it is not an original because the temperature would not go above 29c. I don't know if it is original but it's works fine.
Well, got the battery and NOTHiNG !! So, idk, maybe my N5's just dead. But, the supplier might as well have been from China - Typos, terrible English, the whole 9... Also, my OEM battery's by Sony, but this one says Samsung, so who knows?.. :: shrugs:: I don't trust these companies anymore. Thanks for y'all's input, though.
So not LEDs, no vibration, nothing?
If you have access to a Windows computer, connect the phone to the computer. Does anything appear in device manager?

Nope. NOTHiNG !! Its fine, though. My g/f'd given me her VZW HTC One (M7). So, that'll haveta do till I get my next Nexus (which'll be either a 5X or Google's 2016 offering, if I like the direction the rumors go in...). So, now... OFF to the M7 boards !! Godspeed, everyone ! Godspeed. lol
