optimus black doesnt come on unless charger is plugged in

hey guys, my rooted 2.3.4 stock gingerbread optimus black doesn't come on unless plugged in to the charger. the issue started 3 days ago when i was playing virtual tennis sega and it was connected to the charger. at first my phone got very hot and then it restarted.i continued playing the game after it restarted and it later got hot and again went off, but this time blinking as it went off. i removed the battery and put it back but it remained same. i later removed the battery for a whole day and inserted it back the next day but it remained the same. i later plugged it to the charger and it came on and booted all the way to my home screen. i could even use the phone normally, but anytime i remove the charger it goes off. also, anytime i put on the camera while its plugged in it goes off and shows the battery icon charging. i have done a factory reset but its still the same. please help me.

Try another battery
I think it might be loose or dead
If it was software...it would have turned on

could be your battery, hard to tell though, what if it's pluged to the PC?

I had the same issue.. i lost the warranty due to "bad use" and send the phone to a repair center.. It has a broken wire of the USB connector.

If your phone still turns on while pluged to the computer you can use smartflash to go back to stock rom and this will get you back to warranty

phone still wont come on without charger

am going to the place i purchased my phone from tommorw, since i nw have my warranty regained.......lemme hear what they have to say about it.

Yes i understand it may aswell be another problem...you got a point but bear in mind that waranty service takes a lot of time

[Q] Sudden Death for Note N7000 ?

Hi XDA folks,
I request your help because something weird happened to my Samsung Galaxy Note (GT-N7000), and I need your suggestions for a repair.
What happened :
The phone seems hard-bricked, it doesn't turn on anymore.
No access to download and recovery mod. No charge icon anymore.
It is not the battery, direct charging didn't work.
How :
That's the problem : I don't know : it's a sudden death.
Last evening, I charged it up to 100%, removed the cable, sent some sms, then shut down the screen and went to sleep. At the next morning, the phone was dead.
The phone never fall, nor try to be a submarine.
The phone is almost 2 years-old, but only used those last 4 months.
The phone was never rooted and was under ICS (last samsung update in Belgium).
Request :
Does anyone have an idea about what happened ?
Any suggestion ? Any test to try ?
Is it a known bug fixable ? - or - Can I start sparing for a new phone ?
Thank you very much in advance,
Stefouch

Im the 2 today just a minute ago mine is dead 2.
Have to do a lot of reading here and when i succeed i will let it know.

First of all: test with a different and fully loaded battery.

Like ThaiDai mentioned, try with a different battery. You could be having the same problems that I had.
My battery was swollen. (Due to excessive charging, this reduces battery life like crazy, 70% jumped to 1% in a second.
PLUS
The circuit board of the my charging board is burnt so adb and direct charging doesn't work.
Cost me about $100 to fix them. $50 for each component. Ouch..
If your phone works after using another battery works, you might wanna look into the two problems I mentioned.

To Stefouch ,
Is your phone still dead?
I did not read your first post that good and saw later you cant get to download mode any more.
At first it looked I could not get into download mode , but I had to press those buttons for a longer time ( 30 sec + ).
After all I get my phone working again with a firmware and flash with Odin.
If want to try again to get into download mode by holding the buttons for a longer time I post again.

As mentioned previously, I tried direct charging on the battery connectors but it changes nothing. The battery is not involved.
I also changed the circuit board in a repair shop, unfortunately it didn't reanimate my samsung.
The tech said he can't do anymore unless putting a new Note mother board, but that's almost 300 bucks.

Got like the same problem with N7000. Phone in use for about 11 months. Dropped it more then once but not last few months, find it hard to believe you didn't ever drop in in almost 700 days, but ow well you must be that one in a million guy, hèhè. Anywhooo... Phone was fully charged overnight. It had been of charger for only few hours. Got a call from friend, but I was buzzy, so ignored it. When I wanted to call him back an hour later phone didn't respond in any way. Went to store, they said it wasn't battery but most likely the power-grid or something like it he said. Spoke about changing a module. But as there are signs of damage on the outside they said warranty is no longer valid. He to said the micro USB did not go well in the port of the phone, which he connected to the failure of the phone. To my disappointment I can say, this flaw was present when I got the phone (new!). I figured getting it in difficultly was normal cause I had nothing to compare it to. But feel pretty screwed by my provider. So now I think about changing that specific module, but the guy from the store spoke about billing me around 90 euros (like $130) for the repair. So now feel double screwed by Vodaphone because: The module itself is for sale online between 23,95-32,95 euro, so they wanted to charge me 60 euro for 5 minutes work. I'm totally broke right now so can't tell you if this is gonna work. And with a week waiting till my pay-check is gonna make me whole again, I got the opportunity to learn from other peoples experience. So perhaps this is something for you to try?
I know for sure I got this eMMC Brickbug (tested it with the app) and I'm not sure I updated my Note the right way last year.
So...
Is it possible a new (automatic) update screwed me over and most of all: screwed the hardware?
Other QUESTIONS:
Could it be the Micro-USB module?
I used the phone much for online gaming, so it got pretty hot at the back sometimes. Did you have the same? Can anyone else relate to this?

If you take a light bulb connect it to power and shake it, the inside wiring will reconnect when it makes contact and work again. So changing the bulb is mostly because we THINK it's not fixable or being lazy. Most things we can fix ourselves or with a little help from our fellow users.
If there is still warranty left you should indeed try to take advantage of that. But please ask the guy that fixed it what was wrong and what was replaced and share it with us.
Hope you too will be able to fix it cheap.
Thanks all in advance!

Battery issue ROMs and Warranty

I have not really seen my answer on here so excuse me if I am asking repeated ?tions
My battery is NOT holding a charge, so i went to the mobile store and they tell me that the battery is not designed to last more than a year blah blah blah so i bought a new one since this one drained super fast anyway when using the GPS
So i get a new extended life MASSIVE battery and now it wont charge either. It worked fine for about a week, and now its just yellow exclamation point city.
I cannot get the phone to stay on, I have tried multiple charging leads, used the wall, used the computer port, nothing.
So I guess my only option is to mail it to Samsung as maybe it is the usb port itself?
I only think this as last night when I plugged in before bed it made the connection/disconnection sound like 4-5 times as if to say the plug is not in.
But with that said, even when i would plug in and see that it reads the charge is being accepted, I still get nothing hours later.
So if Samsung gets it, will they go into my phone and see the custom rom and tell me to have a nice day as my warranty is now voided for tampering with the original firmware?
Because clearly I have no way to flash it back to stock since the battery will not charge at all.
Entertaining suggestions
Thanks

You do have a way to flash stock, charge the battery externally/put a new battery and unroot and flash stock. Yes if you send it to Samsung they may notice a root so better to get the original firmware in place. I guess the internal charging circuit is flawed but then it shouldn't have charged the new battery at all, not even for a week.

And how do i charge the battery externally, you left that bit out.

Using some other N7000! Look, I'm just suggesting u, maybe there are other ways to charge externally.

I just took it to the phone shop in the mall and the battery is fully charged, just the phone is not excepting it for some reason.
So the phone is screwed up for sure.
Not sure what to do since I cannot get it to turn on to put it back to stock rom

Send it to Samsung, the circuit must be damaged. Hardware problem, you may get away with a root.

Problem is I have no pc anymore, i only have my mac, is there a way currently to flash the stock rom without needing a pc?

only other way is using mobile odin but phone need to be in working state for that. Try the last option for the service center if it is not even starting they would not be able to check which rom you have and if the motherboard is replaced (just assuming) then there is nothing to be worried about.

Well i took the battery to the shop and they said it was fully charged so its the phone
But now the aftermarket (extended life) actually took a charge when I got home, the phone read 100%, so i turned it on and it said 53% and charging, hmmmm
SO i removed betterbattery app and restarted the phone, then it said low battery again.
So its taking a charge but not holding it now.
I dont remember how to use the Odin since I did the rom flash and so on a year ago and have not touched my phone since I did the root and all of that so I dont remember how lol.
Plus I have only my macbook now and no pc

[Q] Xperia Z1 dead please help URGENT`

Hye guys, I searched all over the internet, couldn't find anything similar.
My Xperia Z1 was all fine today, until it suddenly turned off, and when i turn it back on, it shows the Sony Logo, boots and suddenly turns off.
I tried connecting the charger, and for the first time ever, it shows the battery logo with the amount of charge on it, and it doesn't charge, the LED doesn't light up.
I had around 50 percent battery, so i decided to flash my phone using the software updater, and it wont update, the process freezes and says unable, and now when i turn my phone on, it says some message about update failing and connect to pc.
Guys, my questions are:
1. why the hell doesnt it charge and shows up a battery with charge amount on it?
2. Why does it keeps turning off after boot?
Please help me guys, i really need it and its urgent. Im running Kitkat 4.4.4 and not rooted. Never did anything, but used it as it is. Never had previous issues.

Guys, I just flashed it using the software updater, it did flash but still it boots and dies off, and doesnt charge. Please help. Just shows the amount of battery on it.

It seems that your battery is totally empty or has hardware problem. If you have dock to charge your device use that over night and try again to boot it up.

Right, I will try the dock tomorrow and see, but I wonder why it shows the battery with the amount of charge in it. I still don't understand why the phone recognizes the charger but doesn't charge,
What if i replace the battery? Will it be worth doing so?

Anyone?

May I ask in where exactly it boot up? Whole OS or Sony logo or something else? Also if it show amount of battery how much it show in it?

well, it boots up to that wave thing, u know? Sony logo comes up, then Xperia and the waves keep going on, and everything fully loads upto where the brightness level also falls to the level set and it just turns off.
The battery icon has like 8 - 10 bars, and around 5 bars were filled, but now it has like 2 bars because the battery eventually died as i tried different stuff, but it never charged,

I just bought a new Xperia Z1, I did not have warrenty for my phone here in Srilanka, plus got one of the water indicators red ages ago. I'll try give it to some repair center and get it repaired, but I still don't understand whats up with it, and why nobody else had this issue, like ever.
Thanks for all your support.

sounds like some kind of boot loops!
don`t worry bro. this issue some times happened with a bunch of reasons but always its simply fix by flashing an .FTF of stock ROM on it. so don`t worry about it and if they couldn't repair your phone come back here and tell me to help you.

I am afraid that his problem ain't the bootloop. Problem is that his device won't charge. If one have hardly any battery left flashing any ROM would be problem.

Exactly, because bro my phone doesn't charge. If it charges I would be able to do something with it. But when the battery is dead its gone forever probably.
I did the hard reset, flashed the phone, tried different chargers, it still doesnt CHARGE, but shows a battery icon with the battery level on it.

How are charging it, may be the USB ports are damaged, try the magnetic port or a dock

Tried both the dock and the charger, still connects and shows the battery icon with the level on it. Its so annoying because nobody has ever had this issue.
I handed it over to some repair shop and bought a new Xperia Z1. I will update you guys with the fault of the phone as soon as i can.

hey guys,
I just sent my phone to Sony Center, I gave it to a local shop and he said it seem to be a software issue, but it doesnt still work.

You say you had a water indicator red. I'm no expert but to me it sounds like water damage. Sometimes a phone damaged by water can take a long time to show symptoms.
Bear in mind though like I said I am not an expert

Exactly what i thought, It might be water damage, but the stupid thing keeps turning on until it boots, and the worst thing is it shows the battery with a set of bars on it as the battery level when the charger it pluugged and no LED indication is shown.
