Image 1/1: Be careful when doing this because the middle panel comes in two pieces and if you start at the top, you may break the connection between the two pieces.
  • Starting from the bottom, use a plastic opening tool to pry off the middle panel from the phone.

The photo seems to show that the person is opening from the top, which is the opposite of your advice. So, just want to be clear.

yes, open from bottom first... the pic above shows the finished product after reaching top of phone. I found it best to actually start close to the right of the usbC connector. Pushing inbetween the 2 tabs and up will release the shell.. then work clockwise.

Anyone with the bootloop problem has been successful on returning the 5X to life by replacing the motherboard?

Jago MF - Reply

that's a stupid question. new motherboard means new operating system. maybe you should just use fastboot and flash stock firmware on your phone easy

Alek Kels -

where can I get a new motherboard at?????

Alek Kels -

in most 'google image boot' issues, it is a hardware issue, not software. besides, the phone will not allow a bootloader option.

Chris Mayberry -

same here! if anybody has luck fixing the bootloop problem by replacing the motherboard please let us know

Has the motherboard part been removed from the "Parts" section??? Not available for purchase anymore??? That would render this guide useless

Jago MF - Reply

What do you mean by useless? Mobos from other suppliers require different take apart?

I had bootloops within the year of buying this phone but because the LG webpage RA system wasn't working I missed out by a couple days and they want to charge me $180 to repair the phone. They won't budge and I will never buy an LG again. Has anyone found replacement motherboards or fixed this phone?

How do I do this? I'm having the bootloop problem atm.

Thanks!

Sand.

Don't worry about learning, because it is a hardware issue, not software. The phone will not boot proper past the fastboot.

Chris Mayberry -

It is probably a hardware problem. You can try redoing the software. It didn't work for me. You need to cook your phone. Sounds stupid right? But it works. One of the contacts for the ram or cpu is no longer good. Cooking it will melt the solder and fix it for at least a while. At least it worked for me.

I followed the instructions on a blog. Dev Alex - Oven fresh Nexus 5x.

This is an age old fix for crappy solder points connecting to CPUs or GPUs (most notably in HP laptops). Disassemble the phone and heat the snapdragon chip with a heat gun for 10 seconds. The chip is beneath a metal shield that pops up with a flat screwdriver. I am working to complete this now.. .will let you know how it works.

Chris Mayberry -

..alot of work for a little action. Got the phone to boot after heating the CPU for 15sec, stayed on for 4 minutes before rebooting again. ~sigh~

Chris Mayberry -

Found this forum comment re the rebooting sequence fix...

"The LG G4, V10, and the Nexus 5X are all affected by the bonded flipchip substrate breaking off of the BGA package under the CPU, which usually manifests in bootlooping or screen corruption, and eventually a complete brick. It’s not solder related; the only way to fix it is by completely replacing the CPU package with one that isn’t defective. – FrankTheCat"
