[Q] LG Quantum help

My lg quantum is not working please help

Wow, helpful... How about some symptoms... What is it doing, when did it start, what were you doing last on it?

also, if you ave a device specific question, try the device specific forum
LG Quantum Forum

the screen comes on when i plug it in but it dosent do anything after that

"plug it in"? does it work without plugging it in? I assume you mean USB to PC or power. Maybe a problem with the battery? not seated correctly?
If you turn the phone on and it doesn't respond I suggest you go to the next ATT store.

when i plug it out everything gose black

seeing that you had a number of phones in your hand I assume you know what you are doing.
Your description does not allow anybody to really help you. You need to do a step by step. It may be completely obvious to you when you say when I unplug it it goes black, but it's not to others.
1) what is the state of the phone before you plug it in. Is it working or not?
2) what do you plug it into?
3) when you plug it in, does it play the ringtone or vibrate? It should.
4) When you open Zune software on PC, does it see the phone?
5) when you unplug the phone goes black? Then nothing? just dead?
if it is dead before you plug it in and it comes alive when you plug it in and it goes dead when you unplug it, my suspicion is battery, battery life, maybe not seated correctly. unplug it, plug it back in.
My post would probably be exponentially shorter if you gave more details on what's actually happening.
btw. You did not answer my questions in my post at all. How can I help if you are not answering simple questions? Are you playing a bad joke on us

1 not
2 wall outlet
3nope it just gose to lg screen and stays there
4nope cant see it
5and yep just dead

well, sounds like dead is the correct word to use. Since you can't get into the phone to do a hard reset via the About button. Try this:
1. Power off the phone. Remove and re-insert the battery to make sure.
2. Press and hold the middle of the Volume button and the Camera button. While holding these buttons press also the Power button.
3. Wait until the screen shows "Cold Boot" then release the Power button only.
4. Keep holding the middle of Volume and Camera buttons pressed until the Welcome screen appears.
If it still fails to boot the next is to try to install a fresh ROM for the Quantum. There is one right here with instructions on how to install for several regions.
good luck

Well, guess that's what you get from a dead phone off of eBay. Just saw your other threads in the quantum forum. Try to flash the rom that is posted there. Go to an att store (good luck with explaining you got it fromebay)

it works with other battries but i use a captivate battery and its hard to keep it in to start up

ok i got my battery to day and tryed to do the thing you posted
when i hold the power button it comes on but when i keep holding waiting for the coldboot screen it just turns off

It sounds like your battery was too drained. If thebattery is really ou of charge, the phone won't start up, even if the phone is plugged in. It might take a few hours on the charger to get enough charge in the battery to run the phone. I suppose if the battery is bad, it'd do the same thing but never actually start.

[Q] Xoom will not power on. Tried the vol up/power trick to no avail.

I was shooting a video with my xoom and it powered off to a black screen. The led pops up showing that it is charging and it shows green when it is fully charged but will not register any button presses. I though about maybe flashing the stock sbf but i cant get my pc to recognize the xoom at all even after downloading and installing the drivers. I made created a new thread because i couldn't find anything about a xoom that wouldn't respond to the vol up/power combo. Any help would be greatly appreciated.

Sorry to hear about your Xoom. Have you contacted Motorola yet?

The same thing happened to me, I never found a solution. I exchanged it for a new one at Costco. Good luck.

Haven't contacted Moto yet. Has anyone tried disecting the xoom? Is it tough? looks like a couple screws in the bottom and bada boom bada bing right? lol

Same thing happened to me last night...I powered down the xoom and plugged it in over night, this morning I had a green light but it wouldn't turn on. I tried the Vol up key and power trick, I read someone else that someone was able to get Vol down and power to work as well....neither worked for me.
I am probably going to contact Motorola this morning when I have time unless someone else has a suggestion that works before that.

So did you have any custom mods on your Xoom or was it completely stock? Just to know if stock one can be bricked in that way

Take out the battery for a few seconds and put it back; then while holding Volume UP (+) press the Power Button.
See what happens...

Nothing. Happens it don't light up or power on at all. It is not reconized on computer either. It's hard bricked.

Make sure the Battery is charging...

How can I make sure the battery is charging when no lights come on at all? All I do know is I had it plugged in for a while yesterday and it got really warm. But no lights whatsoever. The screen doesn't light up at all neither does the led.

??????

There are no notification lights on the D720, but when you plug it in with a charger, you should see a battery bar on the display.
Other than that, you are probably right about hard-brick.
I, luckily, never had a "brick" on the Nexus S, so someone else with experience may wanna chime in. But Google and YouTube are your friends.
Sorry...

Please help me, i have the same problem

been awhile since any action here. saved mine with JIG method once but this time it won't work ??!(why) , in search of a solution again! -> hardbrick #2 on this device!

You guys can try a USB Jig. If that does not help, I think JTAG is what you need.

Jesus... just to revive this thread (and this concept of hard bricking), I think I just accidentally bricked mine as well.
Here's exactly what I did:
One moment, it was working spectacularly - fully stock, but unlocked. I had just listed it on eBay, too.
So I ran a factory reset on it (from the Settings menu), also "erase USB storage".
Then, after it shut down for the reboot, I pulled the battery.
...
That was it. Now it doesn't turn on for anything whatsoever. No device detected on USB when plugged into PC. Remove, replace battery, hold VolUp+Power, nothing. Plug into power adapter, nothing. Nothing at all.
But the back does get lukewarm after a minute or so, as if it's alive in the head but frozen, unable to start the bootloader.
WTF? I also have 2 more of these Nexus S 4G's, and both of them seem to have Flash storage chips that exhibit the same behavior when their chips are placed in (this) working motherboard. They can't boot. When I try to "hot-flash" it by booting the bootloader then swapping the Flash chips, they can't flash anything (this is probably to be expected). So, if I can get my ONCE-WORKING phone back to life, there's a good chance I can get another working as well (one just has a cracked glass, otherwise working mainboard & peripherals).
It's old, yes, but it's a damn shame to E-waste these things for a stupid software problem like this!

[Q] Photon Q won't boot up

Sorry if this is something that has been covered before. I searched, and searched and didn't find my exact problem. Any guidance you may have, including links to the appropriate threads is greatly appreciated.
My Q shutdown today while it was sitting in my pocket during a meeting. It was way too soon for my battery to be dead, but I tried charging it, both by USB on a computer and on a stock charger just in case. The backlight on the screen comes on for a few seconds every minute or so, regardless of whether its on hte charger or not. The screen is black otherwise. The battery is HOT, even after being off the charger for a long time. I tried soft-reset and booting into recovery with no luck. Plugging into USB on a computer that has Moto Device manager installed results in the computer alternating between recognizing and not recognizing the device every few seconds (seemingly in concert with the backlight turning on and off) but it does not recognize it long enough to load directories, etc. RSD lite will not recognize the device.
I wasn't doing anything with the phone at the time. It is rooted but not unlocked.
Any ideas? Will I run into a warranty issue since it was rooted even though it's not unlocked?

Have you tried to force reboot (Vol down + Power button for about 7-10 secs)?

Yes. Thanks for the reply. That's what I meant by soft reset. What the issue, I figured out, was that my battery had decided to self-destruct. It didn't have enough charge to even boot the phone successfully, so it was not possible to put it into recovery mode or anything else. I took it to Sprint and they replaced it under warranty.

One mini with bootloader fail. Still alive but not boot up accurately

Hello to all.
I tried to find an answer for my troubles here by a few hours but unfortunatelly i didnt. So I wonder to find help here thanks to XDA specimens society.
Problem symptoms
1 I bought One mini in USA. Seller provided a photo with bootloader screen which I attach below.
2 When received device, it didnt boot up at all. Only a HTC logo appeared at white background and screen began black.
Than when I press a power button, a touch buttons under screen flash 10 times and stop. Again press of power button gives one short vibration and nothing later happens.
I noticed that alu cover at down side (battery area) becomes warm and it is working till battery power goes to 0%
3 When "working", mobile is detected by Windows system connected by usb. It show mass storage, modem and not recognized device.
4 Also it shows a battery charging animation if power button was not pressed before and battery is charged from 0%.
After a two weeks in my desk it still shows 99% what means that battery is mint condition and mobile is not working when not powered on before.
Serviceman said that I have broken bootloader and it should be repaired.
Finally I found out that I can install a new ROM.
So I downloaded a
drivers (recommended here at another article)
TWRP recovery file 2 7 0 5 m4kk
customized Rom by CodenameLungo version CM 11
What I should do now? What tools install? How to putt all these into phone memory if I have not acces to bootloader screen?
If you know article which solve my problem than I will be thankfull for a link.
I know that for most of you these questions are stupid but I m not a pro and will be thankfull for a little help
THX in advance for all who will try to help me.

Do you know how to enter bootloader? When the phone is off, you hold the Volume Down Button and the power button until phone boots up (several seconds). If you can access bootloader this way, we have a chance to help you out.

Yes I read about this method. Unfortunatelly it didnt work. Or i tried power+vol up.
Today I visited another specialist and left it for diagnostic purposes. They suppose that bootloader is damaged and should be reconstructed (if I can name it this way).
They were listening to me carefully before said that wold try to connect it with computer.
I hope they know what to do. Will call them on Friday and post here what s going on in their opinion.

OK. Good luck with it.

Bootloader was reconstructed and now it is running to the boot menu. But serviceman has a problem with flashing ROM. He said that during instalation system cant rebuild certificate and all proces fails at 3%.
May anyone point me any link with instructions what should be done at this situation? We have a deal that on Monday i take mobile back, even if rom will not be flashed correctly...
He confirmed that this phone comes from ATT broadband and is not sure if that change anything or not.
Also suggest that previous owner tried to modify ROM by himself and thats why bootloader was damaged...
