  • 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?

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....

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.

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?

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i can't be bothered setting up a new phone and there is nothing overly off putting about the lg g3 other than the outdated os but mine runs cyanogen mod which i like better than all other os skins

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.

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"?
