Having the same problem. I was on purity rom(4.4.3), with default purity kernel. I flashed the Ak poseidon kernel, with Ukm. It booted fine , was on phone for about 4 minutes, and then I ran antutu benchmark. Before that I didn’t change anything via synapse app. Then when I ran test on antutu phone went off. Non of the buttons were responding. I plugged the phone into wall charger and pressed all 3 buttons. Then the download mode appeared. Left it like that on the charger , went to sleep. When I woke up the phone was turned off. Today I was flashing factory img ( 4.4.3. occam). Following the instructions
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312 [/URL]. Everything went ok no problem in the cmd , only the thing was , when I had to fastboot the booth loader, then the phone stuck in power on loop . ( reboots, then it says google, and reboots again) I was able to stop this by holding volume down, then it goes into bootloader. Finished flashing factory img, like it says on the tut. And the same thing happens. The phone won’t boot, And it is not responding when it is unplugged. Please help :/
