How I go about unloacking the bootloader on a LG K10 without a PC? Can it be done or do I need a computer. Thanks in advance
You will need a PC to run the required fastboot commands. So, yes, it cannot be done without a PC. One alternative can be to use another rooted Android phone with ADB and Fastboot binaries installed. Then connect the two phones using a USB OTG connector/cable and you should be able to use the fastboot commands.
