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

Thanks theaks, turns out to be a good battery issue...... Didn't know that warranty doesn't cover battery...... Optimus works fine now.... ICS on my mind.

[Q] Battery and heating problem

First, sorry for my bad english..
The problem started a few days ago when my phone started to get really hot.. About 49 C, according to the battary software..
But, it is not only the battery, which is hot.. Its mainly the place left for the camera, if you see the mobile from the behind.. And the screen get hot too.. and sometime the mobile shutdown too..
The battery also acts weird. It keeps power only for 2 hours, maximum, and often less than an hour..
I was using the Cyanogenmod 7.2.0 Stable rom, and thought that was the problem.. So i reinstalled the rom, and it didnt help..
Now im running the Nova HD 1.1.0, with android 4.0.4, and the same problem is still on..
Some ideas, why it is doing it?

I think I had the same problem. I got it fixed after sending my phone five times to a repair center. The problem that I had was a defective motherboard.
I think that HDMI broke the motherboard. After I sent my phone for the second or third time for repair, the phone received a board swap. It fixed the problem. But shortly afterwards I tried to connect my phone to a TV again. It worked OK for a while but then, after some minutes, the signal was lost and my phone froze with a black screen. After that, my phone began showing the same problem as before. At both times I was using CyanogenMod 7.x
So, have you ever used the HDMI-out on the phone? And did your phone freeze/crash while using it? If yes, then I am afraid you have a defective motherboard.
Though I am not 100% that that's the reason
Another issue that the phone had was when the phone was turned off, the phone still sucked power out of the battery, resulting a hot phone.
Now I am afraid to use HDMI on this phone.

[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.

Take it to the shop where you got it from , there is a 2 year warranty on your phone.
And you have nothing to loose its dead now.
Yesterday I went to my bathroom and light still working , today its not.
Did not do anything wrong , its how electronics works

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!

Charging problems

I've been flashing roms for awhile and have run into a weird problem that I never seen before...
If I boot up with the charger supplying power, it will charge when power is supplied (plugged in or wireless), but if I'm booting up without power being supplied, whenever I do supply power(plugging in or wireless) it doesn't charge....
I've changed kernels and roms, but it seems to persist...
Any ideas? Hardware/firmware/software?

I have nearly the same problem as you, except I can only use one certain chord to charge, as others won't work. oh, and a reboot with it plugged in doesn't help either. I have to boot into the recovery, while plugged in, then reboot into the system. I don't think its software, but I have no clue, honestly. I thought it was just my device. it started happening about 3-4 months ago.

Wow that's a long time to be running it like that, did your phone ever get soaked in water? Mine did, wondering if that had something to do with it... I do a lot of flashing custom roms so not sure if that's it either tho

Were any of you guys able to fix this issue? I started having the same problem qith my N6 a couple of days ago. i flashed a Pure Nexus rom 2 weeks ago and it worked fine, all of a sudden this issue came up. i flashed back the stock rom and the issue is still happening. my phone has never been wet or anything, it is an over 2yo phone.

I started having charging problems when my Nexus 6 was about a year and a half old, I tried different ROMs, kernels, stock. Nothing helped, till I bought a new OEM charger. The one I got with my shamu looked fine, but was apparently not fine. I haven't had any more problems in the 6 months since getting the new one.

Do you use the OEM Motorola Turbopower 15w charger and have you (most likely have, but still gotta ask) tried other chargers, both QC compadible along with non-QC chargers in different amp ranges? My stock charger burnt out awhile back, it first stopped triggering OC2.0 and instead wouldn't exceed 1400mA, which wasn't noticed at first, then stepped down to only 480mA max. however throughout the failure period I noticed certain cables would have varying speeds as displayed in Ampere, even testing high quality Anker/Aukey/name brand performance cables they would vary greatly even though all could support more than the 15w the charger could output. This lead me to believe a cable problem which then turned into a charger problem and I couldn't get my hands on another QC charger at the time without buying one outright just to test the theory. When I finally found a friend with one it became apparent the charger was bunk as it topped at 2200mA right away with every cable I tried with the stock charger. However shortly after that I started having problems where it wouldn't charge at times leading to me waking up with a dead phone. Thinking its either the solder on the micro-usb port failing or the battery I checked the solder joints first using my shops usb microscope and they were fine. Then I noticed, since I rarely let my phone go below 50% if I can help it, it was shutting down @ 30-50% battery remaining, sometimes it would be only 3-5% I found when testing it. Replaced the battery and shes golden now.
Guess what I'm trying to say is, there are some pretty strange reactions to a dying charger or battery that can make you think its something else, even software related (first thing I did was reinstall PN along with 3 other roms lol). If your not able to find the problem, and a friends QC charger doesn't fix it, spend the $20 or under and grab a battery, cheaper than taking it to a repair shop to just find out the battery is dying and you could have saved a ton replacing it yourself, & even if its not it, now you have a backup for when yours does go out, which it will, only a question of when (google the countless post of N6 batteries dying after avg 2 years usage) lol.

Mi5 Issue with phone/battery, brick every 2 weeks.

Hi,
I'm a Mi5 3/64 (black) user since 1 month, I bought it from Geekbuying.
Since 1 months the phone was hardbricked twice:
First time I left it overnight with 40% of battery and when I woke up in the morning the phone was dead, no life at all. I tried to charge it for couple of hours but it didn't help. Luckily I was able to flash MIUI through Miflash, so after that I was able to turn on my mobile and start again from zero. Terrible.
Second time it happened while I was charging my mobile. When it had 90% of battery I switched the mobile off. After one or two hours, still connected to charger I tried to turn it on but it was dead again. No life at all. I tried to charge it for couple of hours and nothing. So I left it and the next day I tried to turn it on by any chance and the red LED started to blink. Tried to charge for a while, but still without success. Connected to my laptop and it was visible in MiFlash, so I flashed latest Miui dev and now I can start again setting up my mobile.
What should I do now? Does it look like battery issue? I'm afraid that it will happen again after 2-3 weeks.
Somebody else had this issue? Did you ever return smth to Geekbuying and received item or refund back?
I wrote to Geekbuying and they just recommended me to flash this - https://goo.gl/jLBSsa I think it's bull****, just an old Miui ROM.
Thank you in advance for any help.

Was just going to restart the device and flash supersu binarys, tried to restart into recovery, eventually it died, couldnt boot it at all, doesnt respond while charging neither when plugging into the computer. I've no idea what happened but for me it feels like it was the battery failed. I was on lineage 170109 with brand kernel 3.3

Yes, so your issue is similar to mine. Terrible, no idea what's wrong with this phone and geekbuying support is terrible.
Use MiFlash to temporary make your device alive.

Using Mac but don't want to hassle, just bought a new battery from ebay instead and hope it will fix the problem.

On another community people told me that the main board is faulty, they say that it's the common issue in mi5.
