Many users report that after flashing their BU40N to 1.00 (specifically the "HL-DT-ST-BD-RE_BU40N-1.00-NM00500-211810241935.bin" firmware), the drive becomes extremely hot during operation—sometimes too hot to touch.

The exact search "bu40n 100 firmware hot" describes a real, measurable problem: The LG BU40N running dangerously hot under firmware version 1.00. While this firmware is excellent for 4K decryption, its aggressive power and thermal management shorten the drive's life.

The proven solution is to cross-flash to the patched 1.03-MK firmware using SDFtool Flasher. This eliminates the overheating without sacrificing LibreDrive compatibility. Do not let your BU40N cook itself—flash safely today.

The BU40N is an LG/HL DS (Hitachi-LG) slim internal Blu-ray drive. The "100" likely refers to firmware version 1.00 (or a similar early build), which is often sought after because earlier firmware versions (1.00, 1.01, 1.02, 1.03) are friendly for LibreDrive and can be flashed to enable UHD (4K Blu-ray) ripping.

Here’s what you need to know about "BU40N 1.00 firmware hot" — meaning popular or in-demand:

The LG BU40N is a slim, slot-loading 9.5mm Blu-ray drive found in many external USB enclosures (like the Vantec NST-510S3-BK) and high-end laptops. It is one of the few drives on the market capable of reading Ultra HD (4K) Blu-rays—but only if the firmware has been patched or downgraded.

Officially, the drive ships with firmware versions like 1.03, 1.04, or 1.05, which enforce AACS 2.0 encryption and prevent unlicensed ripping software (like MakeMKV) from accessing 4K discs. The nuclear option: hot-glue a 40mm x 40mm

This guide assumes you have a Windows PC and a USB-to-SATA adapter (or an external enclosure that can put the drive into "flashing mode").

In enthusiast communities, the designation "hot" often alludes to "Hot-swappable" firmware flashing methods. Because many modern drives are "flashed" (updated) via software commands in Windows or DOS, users often look for the most current or "hot" version to ensure they have the latest features or specific modifications enabled.

One common reason users seek modified firmware for the BU40N is to bypass Region Coding (RPC-2). Commercial Blu-ray and DVD drives are typically locked to a specific geographic region (e.g., Region 1 for the USA, Region 2 for Europe). They usually allow the user to change the region only five times before locking permanently. Modified firmware resets this counter or removes the lock entirely, allowing the drive to play media from any region.
