    • Release the digitizer and LCD connectors. The two cameras are held slightly in the frame. Carefully remove the motherboard with cameras.

    It was easier to remove the two connectors to cameras on the top to remove the motherboard, than forcing the motherboard out with the two cameras still attached.

Are you able to put it back together?

Ivan Gergi -

Yes the are surprisingly easy to put back together

Hunter destroyer unit -

I have one that is not booting at all. Before that, If it was shut off or if the battery was drained completely it would not power up, even if the battery was at 100%. I would have to remove the battery and hold the power button down for at least 30 seconds. That is not working anymore, it just ill not power on. This reminds me of issues with laptops that typically involve a CMOS battery that is dead or very low. Is there a similar battery (that can be reasonably replaced) in a phone? For it to keep time and retain certain firmware settings I would think there would have to be something like that in there somewhere....

boxfreind -

Hi boxfreind, i've had a similar issue as of heaps of people (search youtuble for blue screen of death). i too thought of the old laptop days of cmos battery and before i seen this site i thought that vibrator motor was the battery lol. anyway, i cant boot my Lg up after 1 year of service (just like many others). people adivse that trying to remove the motherboard and 'clean it' tends to work... i didn't think that was the reason and thought perhaps removing the motherboard was just actually disconnecting the battery from the motherboard to drain the power... but alas, if no battery CMOS then that cant be the reason.

madmac -

quite easy to remove the back , thanks!

Mie Mohd -

I bought a frame and screen assembly, so I had to remove the cameras, earpiece, and additional board at bottom of phone in the process. upon reassembly the screen works great, audio output is fine, although I have to replace the earpiece speaker. Blue-tooth headset connects. but the mic on the phone and on my blue-tooth headset no longer work, any suggestions?

David T -

this really is a good phone for the current price and as a phone reviewer that has many phones and will be getting my google marlin soon i have plenty of quality phones and yet my daily driver is still the lg g3 because i can't be bothered setting up a new phone and there is nothing overly off putting about the lg g3 other than the outdated os but mine runs cyanogen mod which i like better than all other os skins

Joshua jacob -

HI i have problem with GPS, it take ages to fix and even then it looses fix constantly. Is it possible that this is because of GPS antenna? Where is GPS antenna located ? THX!

Tomasz Stawarz -

The middle button has no black sensor pad mark at all.do u think my problem keep the device power on related to power button

sensor pad wear out.

which part i should order ?

joe -

I am sure my LTE module is defect, 3G works. Which part do I need to change? Is it the whole motherboard?

sebroy -

What is the part number of the Bluetooth Chip here?Manufacturer?

Raul Piper -

Has anyone replaced the power cord plug-in port? I just bought one on this site and will want to know how to remove old/install new piece. Thanks for any advice.

James McKelvey -

Hello, If I buy a motherboard from the other side of the world, would it work in my phone or is there any "Region thing"?

Cicero Tiago -

We are having issues with screen flickering and turning to black. Its not the screen itself but I have been told its the GPU/CPU? I do have a sparge LG3. Thank you for the diagram now I feel confidant taking it apart. Where would the piece I need to replace be located?

lori_oreo -

I have an issue with my G3. It got some water in it and now the touchscreen feature is not working. The phone powers on fine, and charges fine, but I cannot access any functions with the touchscreen. I took it to a phone repair store and he was able to access the phone by plugging in a remote keypad. He took it apart to try and clean it, but that did not resolve the issue. He believed that the phone would need a new mother board. My question is, is this an expensive repair. In short, is it worth it to repair the phone, or is it more cost effective to buy a new one

grant tober -

Maybe you can get a display broken G3 (not with the flickering issue) used which people are selling because they don’t want to repair it. Then you could use the old motherboard of the display broken phone and insert it into yours. But remember the storage is on the board itself and if you have a 32GB variant now and you buy a 16GB for replacement parts then you will have the 16GB.
