8125 died, now is acting strange. Red light shows charging, but isnt.?

2 days ago i had my cingular 8125 plugged into a charger . when i woke up it was off and dead, still plugged in?
now when i plug it in (to the stock charger) the red light comes on, but if i take the battery out, it stays on. if the battery is in, it is on. but i cant turn it on. ive left it for 15 hours now, and still nothing
even tried another battery.
when i first put the other battery in it turned on, was booting, but then died. probably cuz the battery was dead. but i had it plugged in as soon as i turned it on.
now the same thing happens.
any ideas?
i also thought i smelled something burnt. like if you have ever had a laptop that had a bad a/c connector and would heat up a bit, or even smoke!
dont know if it was my imagination or what?
thanks in advance

T mobile MDA shows RED LED
that is strange that you post this today, because I just received T-mobile MDA unit from 3bay that has a similar problem.
-The phone does not turn on when I press the power button.
-It does not respond to a soft reset or a hard reset.
-With the battery in, I connect the AC charger to the phone and for about 1-3 seconds the charging LED color is RED. THe LED turns off and I can not get the same result if I reconnect the AC charger.
The only visible sign of life this MDA unit has is:
-with the battery out and the AC charger connected, when the USB is removed to the point where it is not connected to the MDA, the charging LED light flashes red for a split second and the screen flashes white for a split second as well. [I hope this is a sign that there's still life in this MDA, but i'm thinking my unit is truly a brick..]
From all the websites I've searched, this does not seem to be an issue, although for me it is a scary one! Anybody that can help would be much appreciated because I want a working MDA not a dead one
EDIT: It turns out my non-booting MDA was due to a faulty vibrator and flashlight MDA part. After removing these two pieces that are connected to the back cover of the MDA housing, the MDA booted up with no problem.

I'm in exactly the same position - left phone on charge overnight two days ago and in the morning it was completely dead. I have managed to get it to power on for about 2-3 seconds on one or two occasions but now it won't do a thing

Not sure if this will help, but have you tried to push that soft reset button that you have to to push with your stylus when it is plugged in?
Sounds stupid, but my power button is completely dead and I thats how I have to start mine up. I also have to pop out the SD card to get the screen to come out of sleep mode!
I might not work, but hey...worth a try.

Well, I eventually got back up and running. Turns out the battery was completely dead. I used the 9v battery trick and then used my USB charger to get the battery fully charged and all is well.
This leads me to query how do I now charge my phone when I don't have access to a PC? I was using a standard AC wall charger and the phone showed that it was charging but due to the fact that the display stays lit whilst on external power, this eventually killed the battery as the charge indicator appeared to be false.

*as posted verbatim in another thread*
WHAT IS THIS 9 VOLT TRICK YOU SPEAK OF?!?
funny...i'm having the same problem with 2, what were perfectly fine, wizards.
which is what brought me to this forum post.
These two devices were turned off and sat in my desk for months as they were not needed. They were perfectly good, successfully unlocked and upgraded from the advice/steps/tools provided here (thanks!). They were my primary personal and work devices until i was given the option to try a few iPAQs.
Now that I want to go back NEITHER device will boot. On the original chargers (both wall and usb) both devices will display the red light as shown in the pic above, will not boot normally, or via the 2 or 3 button methods common for these devices. The batteries do not get warm, which tells me that they are not getting current...which makes NO sense if i'm using 4 different stock charging options (2 wall and 2 usb) in different locations. One expect some variable would work to eliminate some oddity, but nothing is working.
something odd is going here. how can 2 perfectly good devices and charges suddenly crapout? I could really believe it's the battery, but one is grand spankin new (only used for a month)! Both have the main board die? Both not recognizable on any computer?
Is it possible that the backup battery is causing this? Can it me charged same as the standard if its drained? I know i'm grasping at straws here, but this odd a coincidence.

FOUND FIX
okay..this was too simple.
for some reason the USB will not provide enough"juice" to pop these out of their sleep.
I have been using this great little charging system made by good old Radio Shack that is a single plug with different adapters for all different devices...i've been using it for my iPAQ's, Blackjacks, BB's, ect. SO as a last resort i went and got the CORRECT adapter (as there are many mini usb adapters available) and SHAZAM!!! they boot right up!
don't ask me why the stock wall chargers will not work, but these RS iGo systems are the trick!
i'm going to link to the other similar issue in hopes any other folks having the same issue can benefit from this.

[Q] Not recognized by computer, Red dot of death

Ok so:
Had CM 10.2 nothing else crazy (unlocked/rooted)
One day wifi started acting up (kept dropping) and USB started not being recognized.
Decided that maybe software might be acting up, switched to PA 3.99RC2: FUll Wipe, reinstall
Next day riding out to a meeting phone starts rebooting randomly while running Google maps and music
Keeps locking up and rebooting
Getting really hot
Turn phone off, go to meeting
Phone will not turn back on (solid red dot by usb)
Go home
Recovery no go, phone will not charge on wall or USB charging at all.
Red dot comes on when plugged into wall then turns off after about 30min, plugging/unplugging turns the solid red dot on again.
Put on wireless charger, for an hour
Phone boots up, at 60% charge
USB only charges phone does not send any kind of signal that it is there, no windows sound, nothing in device manager
No charging light at all, but the icon shows as charging.
Have airdroid installed, might try stock google, but it looks like something hardware related.
Has anyone experienced something similar?
Since I don't have ADB working how do I return to stock? (I presume unpackage the distro, airdroid them over, and then install individually?)
I called Google and they say that if they deem that the phone works, not only will they keep the phone I sent them, but they will also charge me for another nexus 4, this is kinda BS and wiht the Nexus 5 around the corner it seems even more BS.
Not sure what to do, as I have about another 1.5 weeks of warranty left. The USB seems jacked up but I am not sure if there are other diagnostics to confirm.

Scroll down to the 2nd post...I'd return it all to stock and RMA it.

Thanks for the tip, I was just wondering how this sort of malfunction happens. I never really used the USB port after I got wireless charging, so maybe some light dropping? I dunno

Cannot properly charge my S5

Hi, i just got my Galaxy S5. Somehow i had some charging problems and after it had contact problems and constantly showing "Connected" - "Not Connected" it completly stopped working when i installed Lollipop. I sent it to a repair center and they swapped the charging port and installed KitKat Stock firmware again. Charging now worked, but after some days the error came back again. I reinstalled KitKat via Odin again and now its charging normally. But i know this error will come again and i have no idea how this is possible.
No matter which firmware i got:
- When plugging in the charger while Android is shut down, it shows a battery with a yellow warning symbol. But the phone everytime detects when the charger is plugged in even if its not charging (when Android is running, it doesnt even shows the charger is connected)
- Connection in Download mode via Odin 100% working without any disconnection problems
What the hell is the problem when its not hardware-side and works when i reinstall KitKat?

Push...
Sent my S5 to Samsung and they replaced the charging port. Charging on KitKat WORKED flawless. After Lollipop Update via KIES it has contact error again and does not charge ... Download mode fully working, Charging while Android running NOT working, USB connection not working and charging while Android shut down shows battery error symbol after 1 minute. But it detects that the charger is plugged in when android is shut down....
Sometimes it detects USB and charger but very randomly and for short periods of time. Right now it somehow detected USB connection and works since some minutes after it showed connected disconnected for several times.

Get the phone replaced, it's obviously faulty

I cannot replace it, only send it to the support again. But it cant be that Download mode is working but depending on the Android version USB and charging is not. This is just not possible and cant be hardware-related.

Don't know if this has been already considered, but: did you try another USB cable and/or another charger ? Maybe its not the phone after all !
Just my 2 cents,
Axel

Of course it can be hardware related, if it was firmware related, it would be happening to everyone

Cause it heats
If it's cool it will charge
Happened to me when weather temperature is very high

me also got this issue
i also got this issue but i finally come to know that it is due to high temperature. After updating to 8.2.1 redmi devices start getting hot very soon.

i had this problem when i was using MiUI rom, i must switch my phone's power to off for it to charge normally. i've switched across to another custom ROMs and it's working just fine, just my personal experience!

Phone Just Died

So earlier this week, I was using my phone with Google Maps like usual. I plugged in my vehicle USB port to the phone to save battery. I had +50% on the phone and 1A USB port. So after like 5 minutes of it being plugged in, my phone just turned off. I tried turning it back on and all I get is the boot screen, then AXON shows, and puff... Phone off again. I tried booting into recovery but phone turns off before TWRP finishes loading. Phone doesn't seem to be charging. Tried different cables and charger to charge phone but nothing. No charge light. Seems like battery is dead because the phone turns off during boot and battery not charging.
Nothing seems shorted. Phone been working great for weeks before this. BL unlocked, Debloated stock, TWRP. Any ideas other than sending back for warranty? Luckily I still have my S7 as primary but I had my Axon for primary for my trip for real world daily use. Needles to say, photos and videos are wanted off the phone.

Have you tried going to bootloader mode by holding power and volume down
If the battery has died, then the phone wouldn't turn on is my thinking as everyone you then it on it eats some vattwry

You didn't mention specifically, but have you tried using the factory wall charger & cable and leave charge for like an hour?

Original charger but with certified Micro-b/USB-C cable I've been using for weeks between my S7 and the Axon.
So I left the phone alone for the last few days as I was busy at work and Just didn't feel like messing with it when I got home. I tried to turn the phone on but battery was dead. The quick flash of red led was the indicator trying to power it up. So I used my Samsung charger as it was right there and the original ZTE cable. Phone lights up charging and so I left it as is to go to work. I get home, the green led is lit, so I'm hoping my phone will power up now. Nope, right back to my original issue. Power on phone, gets to Axon logo then eventually turns off or goes black screen. I tried booting into recovery but turns off before fully loading. I try to charge phone again but no led indicator.
So later today, I'm going to try to boot into fastboot and try the new TWRP recovery. Maybe it was enabling r/w on system that caused this. I had downgraded to unlock bootloader and then installed ZADmix. I've been usuing it nonstop for 2 weeks with no issues. I have xposed installed so I know rebooted a few times to get everything working and it never turned off since then.
Really frustrating as that's the phone that had my pictures on it.

Hi @RoninBlackSoul, so what did you end up do ? Have you found any way to bring back the Axon from the dead or sent it back to ZTE for repair / replacement ? Same thing just happened to me, and for me Axon 7 is my primary phone ... if the phone is really dead ... will neve buy another ZTE phone ever !!!

Honestly not sure what did it. After battery drained, plugged it in to charge for 2 or 3 days. Then remembered some note about enabling write access in TWRP (something like that) would cause bootloops. Which is weird, rebooted the phone a few times when it was working.
Any case, I reflahed the recovery/bootstack in EDL and got my phone back. Been working great 5 months now

@RoninBlackSoul, thanks for the feedback.
Got mine working also, my phone was not charging at all. After suddenly rebooting and battery went dead fast, phone was not able to charge for about two days. After which, suddenly started working again, was able to charge and works normally now. This is weird. From my point of view this could be: 1. some sort of auto-protection perhaps or 2. an actual hardware design issue that manifests at random (for some after few weeks or months after purchase). For the 1 point: I was using a non original cable using the original charger, and the USB type c plug was hot at the time the issue occurred. Perhaps due to that heat some protection mechanism manifested that got reset after phone was completely out of juice. Will use only original cable with the Original Fast Charger from now on, as the usb-c plug of the 3rd party cable was fine with a normal charger (non QC3). Hope issue will not manifest again or, Axon 7 will be my last ZTE device ...

I only use good chargers rated for QC or 2/2.4 amps like samsung, anker, aukey. Haven't had issues since. Plus certified type-c cables at all times
