Hi.
My Nexus 4 got wet a couple of weeks ago and received the red light of death. I assumed it was the battery that was the issue and ordered a new one. When I replaced the battery the red light of death was gone and the display showed me the charging icon when I plugged it in to the wall.
When the battery was fully charged I pushed the start button, but the phone wont start!
I have taken apart the phone completely and dried all the parts in rice. The main board and everything looks fine, but as I said, it wont start.
Does anyone have a suggestion what the issue can be and what tricks I can try?
I miss my nexus...
Try volume down + power to get into the bootloader. Anything?
then

No, that didnt do it either. But I found a cheap used Nexus 4 with a smashed screen today. Bought it and took the motherboard from that one, and voilá! Now it works again.
So the problem was the motherboard.
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.
Okay...Im trying to rescue my sister's data on her Note 3. We've replaced the phone but some important stuff remains on this one. Ive been messing with it for quite some time...replaced the charger port, power button and vibrator flex cable. No luck...except Ive noticed a couple of times after it has sat for a couple days if i plug it in it will display the battery with the charging volt and shortly after the red charging light will cime on. However, as soon as I touch the power button again (to try to boot it) the charging light gies out and im back to square one. Any ideas? Really need to get that data! Thanks in advance.

Dumb question...have you tried a different battery?

Yes..2 brand new ones
Let it sit overnight (or at least an hour or two) with the charging light on. Beyond that...I'm thinking you have a motherboard (or component on it) that's failed, thus kind of SOL on the data.

Hello everyone,
i recently acquired a used P10 plus almost for nothing.
the guy i bought it from said it fell on a carpet and it wont turn on anymore.
the symptoms were:
*black screen
*red led blinking (first 3 fast blinks, later only 1 every couple of seconds)
So i thought to myself, probably battery issues from the fall, maybe it disconnected somehow.
I disassembled the phone, reconnected every cable, but still same symptoms.
i read somewhere that red led usually means battery dead or the small charging motherboard (?) is broken. So i ordered both from Aliexpress and installed them today, but still the same issue.
i connected the phone on the charger without the battery, the screen came on (but it seems its broken also - only vertical lines and a crack, lol).
Any ideas?
should i order a new screen and try to fix it or should i give up? (i read somewhere that people couldn't power up their phone after screen replacement)
thank you guys in advance!
well, i guess ill just give up.
i was hoping for an idea of what to do, but nothing.
a shame really, i was hoping to get it back to work again.
cheers!
Hello,
I have my moto g5 plus for 6 years and I decided to change battery (old one was almost dead)
so I get new one and I did everything according to iFixit, but after 5 hours on charger I noticed that white led is blinking and phone wont start. It shows only flash symbol (when trying to charge) for one second, then turn of and on again to that flash sign,
I can get to bootloader and it says that battery is OK (charging) but if I unplug it from charger, phone turns off immediately.
is that sign that new battery is dead? or did I forgot to calibrate it or something (hopefuly)?
Dead battery sounds like. Carefully inspect its cable and pins for damage.
I opened my phone and noticed that I accidentally cut the red cable on the battery. With some unbending and duct tape, it's working like new, hopefully for longer than a week
