LG G3 D855 will not boot
After rooting my D855 worked perfect until it the battery drained. Now, with a fully charged battery, it won't boot. It's currently stuck at the LG boot screen with the LED's cycling colours. Custom recovery isn't installed so I factory reset it using stock recovery and it still won't boot. When I connect it to my iMac, Android File Transfer recognises a device but tells me it's not available.
If anyone needs any info then please ask, hopefully someone is able to help.
