On to the motherboard, which had the following chips arrayed on it, according to iFixit:
Samsung K3PE0E00A 2 GB RAM (with the Snapdragon S4 Pro 1.5 GHz CPU beneath it)
Toshiba THGBM5G6A2JBA1R 8GB Flash
Qualcomm WTR1605L Seven-Band 4G LTE chip
Qualcomm MDM9215M 4G GSM/CDMA modem
SlimPort ANX7808 SlimPort Transmitter (HDMI output converter)
Invensense MPU-6050 Six-Axis (Gyro + Accelerometer)
Avago ACPM-7251 Quad-Band GSM/EDGE and Dual-Band UMTS Power Amplifier
Avago 3012 Ultra Low-Noise GNSS Front-End Module
Qualcomm PM8921 Power Management
Avago A5702, A5704, A5505
Qualcomm WCD9310 Audio Codec


Does this mean all that is needed for it to be LTE capable is a software update?

The chip is there because its based on the LTE equipped Optimus G and was just redesigned for the Nexus 4 and the chip was left there. Although the chip is there, there is no LTE antenna. There was also no power amp found on the board.

Dislike!

Seriously guys. It's been sold as a HSPA phone. The play store ones do not have LTE.

iFixit reveals LTE radio in teardown.

The LTE is not enabled, and never will be enabled. It is an HSPA+ phone.

I thought it requires additional hardware + that the chip is COMPATIBLE but the other parts of the phone isn't.

It would need the LTE radio to be LTE. Which the nexus 4 doesnt have. The chip is LTE compatible, not the phone.
