Hi All,
I had the dreaded boot loop on my LG v10 in early January, about a month out of warranty. I heard that LG was sometimes replacing out of warranty units, except that I accidentally dropped the phone onto pavement back in October. The top glass had a large spider web on it, but the phone had been fully functional from October to January until the boot loop started . Because of the broken glass, LG told me to take a hike. Usually, the phone would run for about two minutes from a cold boot, and after that the loop started 10 to 20 seconds past the initial boot. Back in August, the phone often started running very hot and battery life became very bad. I heard that all of this heat helped to further degrade the soldering on the motherboard to the point where it eventually fails which is why the boot loop is happening.
I was forced to buy another phone, since I could not be without one even for a day or two. Even with this issue on my LG V10, I got the LG v20 which has been great.
I am stubborn so I kept the LG v10 because I still wanted to try to make it functional again. With nothing to lose, I decided to bake it. ONLY bake the motherboard and not the entire phone, especially do not bake the battery!!!
Make sure that your remove your SIM card and any micro SD card that is installed. Set them aside until you are ready to reassemble after baking.
Definitely, you have to get a set of jewelers screwdrivers, find the right size and unscrew about 14 screws to remove the back plate that is below the rubberized back cover. Under that is the motherboard which is not screwed down. On either side are three screws that hold in the aluminum side pieces. I only removed the 3 on the right side of the phone when you are looking at the back of the phone. near the bottom of the right side you will notice two silver metal contacts that make contact to a thin part of the motherboard. Once you remove the three screws to the side piece, you can slide it a little without removing it and carefully use the screwdriver to lift up two ribbon connectors just below the battery compartment on the right side. They will snap right off but make sure you don't tear them when you are removing and reinstalling the motherboard (or you are finished with this phone). Once the two connectors are released, carefully and gently use the screwdriver to pop the motherboard free.
Now you are ready to bake. Please don't make the one mistake that I made. You need to remove the main rear camera assembly and the two lense front camera assembly. Both of these also have a ribbon cable with a connector to the motherboard. carefully use the screwdriver to pop the connector off and set those aside since the plastic lenses will not survive the baking process. My camera's work, but because I baked them on the board, the plastic lenses have warped and the resulting photos or videos are a blurry mess. I just ordered replacement camera assemblies on ebay for about $10.00 each so my stupidity did not cost too much.
I followed these steps from another internet post.
Preheat your oven to 385 degrees farenheit.
Put Aluminum foil on a cookie sheet.
Take 3 smaller pieces of foil, fold them into a v shape so that the point supports the
motherboard at the point, about an inch above the larger piece of foil on the cookie sheet.
One support on the middle of the motherboard and the others on each end. Place the motherboard (without the camera assemblies attached) On the cookie sheet, with the foil sheet and on the foil supports with the EMI shielding facing up.
Once the oven is at 385 degrees, carefully place the cookie sheet with motherboard on the middle shelf and close the door. Bake for about 8 minutes.
When time is up, turn off your oven, open the door to allow the heat to escape. DO NOT TOUCH OR MOVE THE COOKIE TRAY OR ANYTHING ON IT FOR ABOUT AN HOUR. This is important, because if the solder has been liquified, it needs to cool in place without being jostled to make sure that there are solid solder connnections at the end of this procedure.
After an hour, everything is cool to the touch and you can carefully reassemble your phone.
Snap both the front and back camera assemblies into their connectors.
Gently reinstall the motherboard, shifting the aluminum side piece and jiggling the motherboard so that the board slides under the two silver contact points making sure that you don't tear the other two connectors below the battery compartment. If the board is not going under the silver contacts, don't force it, just slide and gently pull the aluminum side to remove it, you can hold the board at a 45 degree angle to help it get past the right wall of the battery compartment.
Once the board is down you can slide the aluminum side back on and push toward the center of the phone to make sure it is securely re-seated with no spaces at the glass bezel.
Rescrew any of the three screws that you removed that hold in the aluminum side piece.
Make sure all cameras are properly attached and flush in their recesses, make sure the two tabs are making contact with the silver contacts and make sure that both connectors below the battery case are securely snapped in place.
put the cover back on and replace the 14 screws that hold it down.
Replace your SIM card and micro SD card, put the battery back in, replace the back cover and hold down the fingerprint/power button and hope for the startup.
Mine did and I was very happy. It has been on and I have been playing around with it for the last four hours with no boot loop so in my case, baking the mother board is a fix to this issue. Just make sure that you pop out the cameras before baking.
Because I have an LG V20 now that is using the phone SIM from the LG V10, I will use this repaired LG V10 as a very powerful wi-fi only secondary web browser, GPS, music player and game player. I did all of that and used it as a phone with the spider web glass, so now I am back in busines with this phone for limited service.
I hope this helps some folks to save some money, and gets your phone fully functional especially if your LG V10 is out of warranty or had screen damage like mine did.
Good Luck and Best Regards,
