Hi good day, im a newbie here. I have problem with my LG Optimus 7 E900 Windows Phone 7.5, its just stuck on boot logo. The problem started last week, i was sleeping and i woke up because my pillow is kinda hot and then i found out it was my phone. It was hotter than the usual and it was not even plugged in to a charger, it was also stuck to the LG boot logo screen. I tried to unlugged the battery since i cant turn it off, waited for 3 -5 minutes and plugged it back in - still the same. I tried to do the Cold Boot, by holding the Volume - and Camera and tapping the Power button but nothing is happening, it just says Cold Boot and wont do anything. I tried to do the Restore, by holding the Camera button and tapping the Power and i got the screen that shows it needs to be connected to the computer. I've connected it to the computer and Zune automatically detected it and says the phone needs to be restored. For few minutes the restoration was complete and the phone started to turn on again. I was very happy but then, the problem starts again, the phone just turn off and stuck on the boot logo. I've unplugged the battery, after half a day i plugged it back in and the phone turned on. I reset the phone because i thought that it could theres no memory left but after few minutes, it happened again. So my phone is now useless, it will turn on for 10 to 30 minutes if i unplugged the battery for 3 to 5 hours. Is this a software or hardware issue??? I am really wondering why and Im kinda frustrated about LG or WP7 already.
If anyone out there can help me i would really appreciate it. If you have the same problem, lets help each other so that we can have our phone working again. Thanks for reading! Have a great day!
please help
This is hardware problem. You have to buy this board:
You can buy New SIM Card Micro-HD Flex Cable for LG E900 Optimus 7 from ebay.com, sefelectronics.com or mobile-cherry.com.
I recommend to buy it from mobile-cherry.com. It 100% works!

Hi sir, thanks for your reply. after two weeks, my phone starts working again. its been two days now and still working fine. what happened is that i tried to charge it when it was off, after 30 mins or so i turned it on and it works. but i noticed and smelled burnt plastic. i stick my noise on the micro usb part and its really smells something is burning inside but the phone is still turned on. i took off the back cover and i felt that the upper is hot and the battery seems to be ok.
i guess my concern is, is it okey to use this still? im afraid that it might explode or something while on my pocket. what would you suggest?
thank you very much!, i really appreciate it.
I solved this problem by disabling the detection of the position in the menu settings. You should have a lot of patience in being able to restart it at least once to enter the menu, possibly leaving it off and without battery for a whole night.
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'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.
Hello everyone im really hoping you guys can save me here.
Ok so The phone is a LG G2 D802 16gb
because the phone was dropped i had to get a new screen. i also got a new battery as well as when trying to remove it i broke the seal.
the phones been without a battery connected for 3 days. now with everything reconnected i cannot get it to power on when holding the power button
also plugging it in to charge appears to do nothing. (however i can feel a chip getting warm so it must be charging.)
When i try to power on i literally get nothing, no sound, vibration or screen.
so i tried the solution in https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
Now when i jumped the pins it did show signs of life. i can see the screen is lighting up, but is black. (which apparently it should be)
when i connect it to the computer its recognised and maps about 12 partitions. but they are unreadable by my windows 10 (i assume is normal)
I then used the tool in https://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
i used this to unbrick the phone, i can see in the tool it was copying data successfully into them partitions on my phone. but its made no difference at all to its original state.
Does anyone have any suggestions?

Hello to every one,
I need your help. I don't have any other ideas anymore.
Yesterday evening I plugged my phone (LG G6 H870DS) at around 10% battery on my charger went then on to do something else.
When I returned my screen was completely black/turned off and since then my phone doesn't respond to anything anymore and I also can't detect it anymore, when I plug it into my pc.
I already tried everything I thought that might help (any combination of button presses, charging time, ...).
Do you have any other ideas what might help before I sadly have to call it a definitively dead phone?
