You don’t get to hear this very often, but someone managed to upgrade the RAM on a LG Nexus 5X from 2GB to 4GB. Yes, you read that right.
An XdaDevelopers member had a problem with his Nexus 5X, the cause of which was a bad CPU. The official LG service center in Hong Kong, where the device was bought from, denied to replace the CPU for the user. That’s when he contacted a local repair service in China, who agreed to fix his device.
The user sent his device to China, and while changing the CPU, the technician advised to upgrade the RAM as well. This is because the RAM and the CPU are packed together. The repair was a success and the user now has an LG Nexus 5X with 4GB of RAM.
Recently, the user also managed to install Android 7.1.1, and everything is working perfectly, including the extra RAM. The repair cost him $60, which is pretty good as it brought new life to the dead Nexus 5X.
