Hi All
My friend recently gave me his LG G2 as it had a problem.
What happens is currently if you try and turn on the phone nothing happens. When you plug the phone into the charger the red led blinks and nothing else happens. He told me that he got the phone brand new off eBay and that the problem started after he left the phone plugged in overnight. No software modifications have been done to the phone prior to the red light issue.
After some investigation into the issue i found nothing except another eBay listing with a LG G2 D802 where the guy got water into his phone and it has the exact problem where the phone does not turn on and a red light comes on when attempting to charge the phone. The eBay listing also says that the phone was seen by a service technician who said the circuit board was damaged but is repairable
Before i spend any money buying spare parts does anyone have any idea on what the problem is and whether its worth fixing?
Thanks
Could it be that the motherboard got damaged?
I don't think the mother board got damaged. I had the same problem with both my G2's. (D800 and LS980)
I had changed the motherboard from ls980 to the d800, I connect everything, LCD, digitizer, battery,front and back camera ..etc..
I go to try and power the phone up but nothing happens..
I go to plug in the phone.(Nothing happens)
I use another charger(nothing happens.)
My phone wasn't water damaged though. In your case you could open up your phone and disconnect the battery connector, After about 1-3 minutes connect it back & leave phone alone.(don't try to power up)
I had a problem with one of the phones not having the red LED light coming up to tell nevit was charging. I switch the battery to another bezel & motherboard & it shows 40% battery level.
It definitely worth a try to open your phone & disconnect and connect the battery if the phone was charging one night.. I remember seeing a forum on here that the phone might be still on charging mode or something.

Hi,
I have the same problem, the only sign of life is a red flashing led when I try to charge it up.
My lg g2 (D802) did get water damaged tho, however I don't think it has been damaged that bad. When I found it in the watery environment it still worked, but it was quite warm. First hour or so I put in in a towel, because I wasnt home. When I got home I discovered it was dead. Then I put it in rice for two days, but now this problem occurred.
I reconnected the battery (twice) but it didnt change a thing, and now it still won't boot up...
Hopefully someone can help me (or sees this at all),
Thanks in advance
I have the same problem with my G2. I changed the motherboard after it got water damage but nothing else changed. what should i do?
Solution for blinking red error
Hello Guys,
I have the same problem like you others. 8 times red blinks, phone won't charge, PC won't recognize it, dead at all. But I found the solution. There is a short circuit on the moterboard. That can be LCD, digitizer, buttons or anything other. I have unpluged digitizer connector and BOoM!, connected it to charger and turn on with power button. So you guys can test what's making problem on your MB, it can be anythinhg. I hope that will help to someone.
Sorry for bad English.
same thing here
I have an LG G2 that I recently replaced the batter (ordered from ebay). After the install, the phone just blinks the red indicator light. When I hold the power button, it blinks 8 times, pauses then starts over again blinking 8 times and pausing. Please help.

I have the exact same problem. recently bought a new battery, because my original one is increasing in size (very strange) and decreasing in power.
When i put in the new battery the phone doesnt work if i try to turn it on. When i connect the battery to the charger its just the blinking red light...

I'm having the exact same problem...working ls980 phone using to restore my D801 motherboard....but have no power.
When I plug the ls980 board back in it works again. Last time my D801 board red led blinked 2x but wouldn't startup with its own battery. How did you fix it?
It is the battery. either the cable is ripped or the battery is at 0 volts I've just tested this on my LS980 using my analyzer to fully charge a battery externally to 100% made it work fine, please check the battery cable its very thin and very easy to rip without knowing it. (I work at a battery store) Hope this helps some of you!
A solution for 8 Red blinks:
If you have 8 Red blinks when you change the screen the Solution is:
The two metal joints from two small boards (besides volume and power button) that connect to the motherboard they should be completely attached to the connector.

hi! i have a dopod 838 pro. and it suddenly cant turn on. i was just texting then it went buggy (hanging up) then i did a soft reset then all of a sudden it didnt turn on. i was charging it at that time.
the phone never got wet, was never dropped. i installed the official wm 6.1 rom and it had been running for more than two weeks so i dont think the problem was the ROM. battery is good since i still get two days of battery.
i have tried hard resets, used the usb connector to power the phone up. havent tried another battery though. is there any way i can diagnose the problem before spending for diagnostics in the shop?
this was an observation: when i remove the battery and connect it to the charger, LED is red then it disappears when i replace the battery. no amber going. how do i test if the problem is in the battery? battery connector? power? or (please i pray not) the motherboard itself?
a little help please! more power to this forum. thanks!

Would suspect the battery... Red LED WOULDN'T turn on if this was a hardware problem, broken battery connectors and such. However, if you install the battery when the red LED is visible (connected to charger without battery) & it doesn't turn amber (charging) then I'd suspect the battery has died.
Take in to a shop and ask to try a battery, easier if you know someone with the same phone.
Cheers...
i have it sent to the authorized htc center here in our area. the technician tried using another battery but still it didnt work. my phone will be left at the shop for about 4 to 5 days for diagnostics. the technician said that theres a possibility that this may be a motherboad problem like the board short circuited.
but how come? how can this happen?
can anyon confirm that this is a motherboard problem? awh! cant wait for the result of the diagnostics.
thanks!
Hi, I just replaced my broken LCD but now it won't start. I'm worried I might have damaged the battery and I have damaged the logic board. The very little black thing pointed with an arrow in the picture below is hanging by a thread.
Symptom :
When plugged in USB, the red light flash constantly
Screen does not turn on, no vibration
If I unplug the battery and plug the USB nothing happens
I'm trying to diagnose wether it's the battery or motherboard or both that are broken
Question :
Should it start with the battery unplugged (it does not)
Should it start with a broken battery plugged
Do you think the little black thing I half broke can prevent it to start
Now that the screen is not broken, can I get the rest of the phone fixed by the warranty or they will be able to tell I opened it
Thanks !
No its not ur battery. The red light issue appears with nexus 4 a lot especially when your battery drains out to 0%. Let it charge for couple hours.

I ended up transfering the internal from another nexus 4, and it did the same thing. As you said, after charging for a while it started normally.
Although I still can't tell if the first one is working, I'll have to reconnect it to a broken screen and see if it boot after charging for a while because I forogt to do a nandroid backup of this one
Hello everyone,
I was going for a swim in the pool three days ago and have forgotten to put my Nexus 4 in my duffel bag. The phone was submerge along with my swimming short for over 30 seconds :crying:. I dried off the phone, opened it up to removed the battery, and dried it off with a hair blow dryer for five minutes continuously. Then I put my phone in a bowl of rice. Its been two days hoping that the moisture is gone, I plugged it to a wall charger and have gotten the "blinking red light of death". Next, I removed the battery and charge the phone with out it, giving me a boot loader screen with the green android and the Google logo. But putting the battery back and turning it on only giving me that annoying blinking red light. I hope all the phone component is still good. So at this stage can you guys tell me if the battery is dead and would purchasing a new battery resolve this issue? Any input to resolve this red blinking light would be helpful, thank you for reading.

I have charge twice and installed the battery back and still get the blinking red light. As you have done this before, how did you go about doing it? Was the battery suppose to be "hot" when its being charge? Did you soldered the charging cable "hot and neutral" to the battery positive (+) negative (-) as shown in step 7?

I'm not sure the battery was hot during the process #7..
I took some old phone charger, cut the two wires apart (the positive and negative), and just made them touch the relevant spots on the battery (no soldering was made).
Did you wait more than 15 minutes during this charging?

Thanks for your reply. I also used an old lg charge with the right amount of Voltage ouput. I think it was 5 Volt or something and just split the cable, made it touch the relevant spots and used it electrical tape to secure the the charging charging cable making sure that the wire made contact with the positive and negative spot. Im not sure which cable was positive or negative, so I had to swap cable around and recharge every 15 minutes trial. I know my connection looks messy but thats the best i could do to make sure the make contact at the charging point on the battery. Is this how you do it? lol

Basically it seems fine.
There are two more things I recommend trying:
1. Try charging it for 30 minutes.
2. When plugging the battery back, just plug it, and don't screw the two screws of the battery.
Try these two things - and keep updating if the red light still shows

I have tried charging twice with 30 minutes cycle on each attempt, and have installed the battery back to the phone without the screw of the battery. I tried turning the phone on by holding down the power button for 10 seconds, but there was no Google logo splash screen. The same thing happen on my second attempt, no Google or boot-loader screen. I plugged in the wall charger and let it sit for over two hour and still cant turn it on, only the blinking red light. Removing the battery, charging directly from the cable, and holding the power volume button down at the same time gave me a boot-loader screen and Google logo but the phone immediately shut off. Any ideas what else I could try? Could you tell me about where my phone is damage base on the picture from my earlier post?
If you see Google's logo, your phone can run fine. The problem is probably the dead battery. Consider replacing it with a new one.

Thanks i just order a new one yesterday, just thought I give it a shot instead of buying a new phone. Lets hope its as you say. Thanks for your input.
Ordered a new battery, and it booted up fine. The important thing is that the blinking red light of death is gone so far.. thank goodness! Looks like the battery shorted out when my phone was submerge in the water. There is one small yellow streak line on the bottom right of the screen now but I can live with that. Glad nothing else is damage Thank you for all of your help! Cheers!
What we had:
Nexus 4. with cracked digitizier, but finely working. (except the battery, which lasted less than it should) i tried to remove glass, of course with no luck. Ended with no image on lcd. but phone worked fine, charged, connected to pc, played sounds, etc.
2 weeks of waiting for new lcd. I didn't charge it all that time. (my bad)
So after replacement, i tried to power on, aand it didn't show any signs of life. Put it on charge, red led blinked once when i connected usb. (there was no red led any time after "first charge")
So now:
When i power it on without charge it gives one short vibration. No led or image.
When i put it on charge no reaction at all, but when i hold power button it gives the same vibration and if i hold it for 8-10 seconds more the red led blinks. It stops blinking only when i release power. Also, when the red led blinks, strange repeated noise comes from charger.
Also, i'm not sure about lcd, but it should be fine. No reaction from pc, also.
Your ideas? Hoping it's not the motherboard fault

Take the back off again, unplug the battery and replug it. Then try to boot/charge (you can do this without replacing the back, in case you want to try again). If this doesn't work, you may need a new battery. Most likely the battery itself is fine, but maybe the connector ribbon was damaged.

I tried. Maybe. Now i'm looking for donor.
Hello guys!
I've dropped my nexus 4 and the LCD crashed completly. Then i bought a new LCD (only LCD) and tried to change by myself, but everything went wrong, i couldn't attach it with the glue that they sent me and i saw some cracks on the display.
After the "change", the phone does not turn on anymore, just blink the notification led with red color.
Now i'm thinking to buy the full display (LCD+Display) and try to change it again, i mean, it can't be hard to do, you just have to connect the cables and close (that's what i think).
Is there a way to discover if the full display will bring my phone back to life? :crying:
Thank you!!
Up :crying:

The blinking red LED could indicate a fully discharged battery. Try leaving it on a 2.0 amp charger for a few hours to see if you can get it to boot.

I've tried it but the phone still the same. Maybe it's happening due the display is broken (cracked in the top right). I've installed a new one lcd thinking this could be the problem but now i'm thinking it's the display. Is there any way to test the motherboard and see if it's ok? If i could test the motherboard, i could decide between buy a new complete display (lcd + display) or another phone.
Thanks!
I don't know of any way to test the motherboard without a working display.
Heeyy, i've tried a new one charger, the phone blinked the red light a few minutes and then the screen turned on, but unable to see anything, due the broken display, but² the power button dont do anything, not even to turn the screen off. By this we can conclude that the motherboard is ok, and the problem is the display, right?
I've attached the photo of the screen. The white traces is where the display is "cracked", not really cracked, it's like a kneaded cloth, but it matches the cracks that the screen had.
As a test of the motherboard, let the phone charge with the new charger for a couple of hours. Then, try and power up the phone in fastboot mode, and type "fastboot devices" from a command prompt. Hopefully, the command will return the phone's serial #.
