[Q] Mytouch 4g died in sleep? - myTouch 4G Q&A, Help & Troubleshooting

So, this phone was working without any problems but then my wife turned it off and left it in the drawer for about 3 weeks when she went overseas. When she got back and tried to turn it on it wont turn on. We figured it might have drained the battery so we plugged it in but now its not charging either! When I unplugged and plugged in, the LED blinked orange once but now it wont even do that either, no power, no LED, not charging either. I have tired everything, left it disconnected, battery out for an hour, then put it together and tried to charge, still nothing.
Any ideas? It is already out of warranty so talking to T-Mobile is out of question.
Nothing has been done to it, it is physically fine, it was just off for a long period and not it just wont respond.
Edit: Fixed it! I don't know what, I was almost giving up, but I took the battery out and blew hard on the battery contacts in the phone and in the charging port then plugged everything in and put it back on charger, orange light started to blink and then went solid and now its charging. I just turned it on. This phone is dodgy, no other phone hard bricks like this if you leave it off.

Some phones don't function with completely discharged battery. Actually, most of newer phones. You need to leave the battery inside and the phone connected to charger for some time, till the charging light shows up. MT4G is very far from being "dodgy", doesn't differ from many other phones that behave the same, and you were nowhere near "hard brick".
Good luck in powering up Motorola Defy with completely discharged battery.

Recoverable problem

Had a similar problem. Phone died while using it then wouldn't light up when plugged in. Left it plugged in for half an hour wouldn't seem to charge via wall or car charger. Tried doing a hard reset with/without the battery & plugged in/not plugged in in various combinations. Got nuthin. Drove around for hours looking for a replacement or open T-Mobile place, until it got too late and I went home. Live chat with T-mobile rep was a waste of time. Plugged it in the wall and left it, as this once brought back a G2 battery that I thought was cold dead. Five hours later it was lit up and charging, showing 40% charge on the battery indicator app once I turned it back on. "HTC Sense" crashed immediately on boot then recovered. Seems to be fine so far.
- Suggestion; plug it in and leave it overnight if it seems cold dead and doesn't appear to be charging. It seems to need to hit some critical threshold before it will work again (as indicated by previous poster). Also pick up a couple spares off amazon or newegg if you don't have a second phone available.

X2 Charging problem

So the phone was really low, at 6% this morning. SO I put it on the wall charger. I saw the icon come up that it was charging and then put the phone down.
A while later I went back to the phone and saw that although the charger was plugged in to the wall and also plugged into the phone, it was NOT charging.
Using the phone I went to my contacts to check a phone number and then it turned off, due to no charge.
I plug it into the wall charger, the USB connected to the computer, as well as the car charger and here is what happens:
The top and bottom of the phone blink red for about 1-3 minutes.
Without pressing anything on the phone it automatically turns itself on, I see the Sony Ericsson boot screen, the Windows boot screen then my SPB Mobil Shell screen for about a second and then it turns off again showing and the blinking red light for about 1-3 minutes and then it starts the process all over again.
I think that a setting for Backlight/Power management was changed. As setting similar to "Only charge with usb", or "only charge when connected with ActiveSync" or somthing like that.
The problem is that I turned off the Active sync on the phone in order to conserve battery power so that I could look up the phone number from my contacts. And after I did that the phone shut off and I cannot change it, because it will not charge.
I do not have a different, charged, battery to try and do not think that I can find one easily.
Any suggestions?
Now when I see that the phone is re-booting(I see the SE logo), I use the stylus to to soft reset. It is obvious that there is some type of charge happening before it re-boots, , otherwise it would not re-boot. SO my theory is that by doing a soft rest between restarts, the battery will gain more of a charge each time. And possibly have enough of a charge so that I can go into my settings and see the backlight/ power settings have been changed.
So I took a battery from my old SE 902 phone and rigged it to work with my X2.
It booted up just fine. I was able to get into the menu for power settings. Nothig was changed however I did check the box "do not charge when connected to the computer" backed out of that screen and then went back into the screen and unchecked the box.
I powered down the phone and the screen went to the default charging battery meter.
I then put the proper battery in the phone and it was still blinking red. I saw it blink green for a few seconds, then I felt it vibrate, and then I saw the green battery meter. But after a few seconds it went back to blinking red and I could not see the battery meter again.
This seems to be happening intermittenly. As of right now there is a green blinking light and I see a dimmed battery meter.
Hopefully it will be fine, we shall see.
So it was charging for a while and now has stopped. I see the battery meeter, but there is no green bar moving up. and the light has stopped blinking.
I unplugged the usb and I still see the battery meter with no green bar moving. Installed the back cover and plugged the usb back in.
Now it is back to the red blinking again. . . ? ? ? ? ?
I think that it is a battery issue.
CAn anyone suggest why a battery would all of a sudden stop working?
Just ordered a new battery. $70.00!!! Ouch!!!
It does come with a battery charger for use with a Mini USB, but still, $70.00 is a lot of money!!
I will update with the results after i charge it up.
I got the new battery and put it into the charger. As I mentioned in an earlier post the new battery came with a separate charger for use with a mini usb. At first I had problems. The charger would not charge the new battery. I was using a wall connected mini usb to power the charger. So I went to the computer and tried the mini usb from there. It still would not charge. So I took the battery out of the charger and put it into then phone and went back to the wall charger and it was charging. I could feel the phone vibrate and then saw the battery meter slowly fill with green and back to empty and then fill green again.
So I decided to do a few other chores around the house and went to check the charging status after about 10 minutes. I noticed that the phone was on!! I did not turn the phone on. No one else was in the house to turn it on. It was just on. Weird.
So I took the battery out of the phone and decided to try the new charger again with the computer mini USB. It WAS charging this time!! I charged the new battery on this charger using the computer mini USB until the red light(charging) turned green (finished charging) and then put it in the phone. It works fine.
I then decided to put the defective battery into this charger and it was actually charging!! I left it overnight and it was green this morning: identifying it as a full charge.
When the new battery is down to 10% or less I will take it out and put the defective battery in and see what happens.
So I put the original battery back in after the green light came on identifying a full charge on the accessory charger.
It showed 1% and a message came up identifying that "the battery is low, please charge asap", something like that.
So, in my unprofessional opinion , the original battery is toast.
The new battery worked great after its initial charge using the included accessory charger.
When I decided to charge it using the phone itself with the wall charger I noticed some really weird things happening.
First of all you should know that I downloaded and installed Spoon Charge. Look it up here on the forums, free and works great. It basically tells you what charge level you have, temperature of the battery, what voltage is coming in to charge it and also type of charge the battery is doing: trickle, fast, very fast and on battery.You can set it to read reading at specific time intervals: I have it set to read at every second.
I noticed that the charge kept bouncing between very fast and trickle. At one point it went to on battery, then to trickle then to on battery then to fast.
Ok. Weird. . . I thought to myself.
So I let it continue to charge overnight.
The next day I "tried" to use the phone. it was as slow as it was at it's factory installed settings before I did the memory card fix, accelerator settings, and other fixes that I forgot now have forgotten that I have installed.
At this point I decided to drain the battery as fast as I could by turning on WiFi, Bluetooth, and play a movie at the loudest volume possible. As soon as it reached 10% I took the battery out and charged it with the accessory charger. The next morning I saw that the indicator light was green showing full charge and installed the battery in the phone. It booted up and I immediately received a message that the battery was low, saw 1%.
Knowing that this was a BRAND NEW BATTERY, I turned off the phone and took the battery out and waited a few seconds until I put it back in and rebooted the phone.
This time it said 86% charge!!!!!!
WTF!!!!
So I tried to use the phone and it was as sluggish as before. After about 25 minutes it was starting to be a bit faster but nothing like it was before.
I am really confused now. Since I have a new battery I have ruled out that as a problem. So now is it the phone itself? Could it be the wall charger that is faulty?
Any other suggestions would be greatly appreciated.
Another update.
I put the original battery in the phone and now it works!!!! The old battery that would not charge now charges and works!!!
The phone is not the same. Still really slow, can't get it out of the "LOCKED" position when I want to answer a phone call. Opera is sliggish then fast then sluggish. Not what I had the phone at before all of this started. It actually WAS stable. It WAS useable. Now I want to throw it into the drink!!!!!!
Not sure what to think anymore.
well bro go into the system help of ur mobile press as i say
2ce the end button one time call button, 2ce the end button one time call button,one time end button and u will find the problem it is in the charging port the same issue with me

Computer reset and now phone wont turn on

I was changing the frequency of my video card and the screen went blank and I had to reset my computer. After resetting my computer I looked at my phone (which had been plugged in and charging to my computer) and it was off. When I tried to turn it back on the screen flashed for maybe half of a second and went back off. I am using a HTC EVO 4G rooted with gingerbread 2.3 ROM

Sounds like for whatever reason, your battery may be completely dead. Maybe something weird happened when the computer reset...I'm not sure. Do you get a charging led when you plug the phone into the wall (A/C) charger? The USB from the computer isn't strong enough to charge the phone when the battery is completely dead, so you need to plug into the wall. I would charge it up for a while, and then try to turn it on again. If you don't get a charging led at all when you plug it in, I would try a battery that is known to be charged up if you have access to one. Good luck.
It also wouldn't hurt to try doing a battery pull.

It was dead when I first plugged it into my computer and then it started charging. I plugged it into the wall and it still wasn't turning on and wasn't getting a charging LED. I left it on the wall for about 15 minutes and nothing still, right now I have my battery in the freezer. I read somewhere putting your battery in your freezer could fix it or it could be completely wrong.

Take it out of the freezer, leave the phone alone for about an hour then but the battery in and plug it up. When the led light comes on, don't turn the phone on just let it charge. This has happened to me a few times and I thought I screwed something up but I did what I just told you to do and when the led light came on I let it sit and charge and then turned it on in the morning. I think the battery discharged somehow (guess), good luck.

Yea, I'd put it back in the phone and plug it back in. Let it sit for a while, an hour or two. If you don't get an led in that amount of time, you probably won't get one. You can take your battery to sprint and they should be able to boost the battery and bring it back to life.

Phone issues charging and powering on

Ok so, last night my phone was dying. I didn't charge it until about 5 PM today. However when I plugged it in, it wasn't picking up charge. I took off the battery and it looked like there was water under it, not a lot (no I haven't gotten my phone wet... or near water at all) so I wiped it off and plugged in a spare battery that I have. When I plugged that in, the camera flash turned on briefly and the phone began to blink orange. I left it plugged in for about 20 minutes then I tried turning it back on and nothing. Now when I unplugged it again I tried doing other thigns like turning it on without a battery while it's plugged in, doing it through usb (which when I plug it in through usb the PC makes that USB sound) and for a brief second I tried turning it on, and it DID show the "MyTouch 4G" logo, then it shut off. It hasn't been picking up charge right and I can't get it to turn on... What can I do? I got this off of craiglist and it was working fine for almost a month, so there's no warranty. Any suggestions?
Also, whenever I put in the "good" battery, the phone vibrates and the flash turns on. What do you guys think could be done??
And when I plug it in through USB it looks like it's "charging" (as in the light at the top is orange) and the buttosn turn on if I mess with them, but no image on the screen. Frustrating.

[Q] Phone suddenly went dead (latest MIUI 2.6.35 kernel)

My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).

[Q] n4 is completely unresponsive (dead)

So this is what happened:
the phone discharged fully and i connected it to charge. then i got a flashing red led. seeing this as a bad omen i tried to turn my device on - no luck - it wasn't responding.
i unplugged the charger and plugged it back in and again the same result, then again..... and i got a solid red light. so after a few times of messing about with it , trying out a few sources of power and such i got it charging (the battery logo appeared). The charging lasted for ~30 sec and it went black.
So after that the n4 is completely unresponsive. No flashing leds no backlight on screen, NOTHING.i tried out a few chargers and cables and beside those i used a genuine n4 charger (it's 100% working - i tried to charge another device). i left it there for the whole day to charge thinking that maaaaaby the battery ran to a complete 0 and i just need to give it time, as you probably guessed it, that did nothing.
In fact, i think the phone is not charging at all. The reason i think so is because the wall charger is emitting a faint high-pitch squeal regardless of the fact that the phone is connected (it should be squealing only when it's plugged into socket and the phone is not plugged in it)
so TL DR:
n4 is completely dead, no signs of life. The things that were tried:
a handful of chargers and cables that are 100% working on other devices
trying to boot with a combination of volume buttons pressed
holding the power button for 60 sec. while plugged in
prolonged charging (~7 hours)
verbal threatening to sell the damned thing if it's a serious problem
so that's that. i should get my tools back from a friend on monday. i'll try to take it apart, maby there's a loose connector here or there or something. Any ideas what i could try before that?
Some searching around the forums wouldn't hurt. Try this for example.

thanks for the link, that seems to be worth a shot.... i'll be able to take the phone apart on monday, that's the earliest i will be able to try it. i was wondering if there is anything i can do until then to remedy the situation. I mean i'm really getting a kick out of my old sony erricson k300 but i kinda prefer the nexus and would prefer to fix it asap.
ok i fixed it
i used a 3v source and held the contacts manually for 5 min. that returned it to the red blinking led state and after leaving it to charge for 5 min it returned to the battery icon on screen. thanks for the info again.
