Emisar D4V2: Anduril 2 HEX File Selection for Flashing Firmware
One great thing about the Emisar D4V2 is that it can be flashed with newer versions of Anduril as updates come out. However, figuring out which HEX file can be confusing. This guide will give you some pointers on how to select the right HEX file.
Already running Anduril 2?
For lights that are already running Anduril 2, I highly recommend that you get a read out of the version that is currently on your light. This will give you a 12-digit number with the last 4 digits being a model number that can be used to correspond with HEX file loaded on your light.
From ToyKeeper’s instructions:
Use the version check function to find out which flavor of the firmware the light shipped with. It should blink out a date and maybe a 4-digit number after the date –
YYYYMMDDNNNN. Write this down. Version check is
15 or more clicksfrom Off.
Match up the 4-digit
NNNNnumber in the MODELS file.
Find the newest firmware for that model. You may need to scroll down to reach the newest files.
Upgrading from Anduril 1
If you’re upgrading from Anduril 1, you won’t have a reliable version/model number you can map to a HEX file. In this case, to choose the correct HEX file, you should consider both the emitter and the driver in your D4V2.
Notice how some drivers actually use a file named
You can, theoretically, flash the
noctigon-kr4 HEX with the 219B emitter, but
you run the risk of damaging the emitter. We don’t necessarily own
these lights because they’re the most safe lights, right? 🔥
White and red colored Emisar D4V2 drivers
NOTE: Besides the color differences between the above drivers, also notice some components and capacitors on the white driver that are not on the red river. ToyKeeper has commented on this:
The board color doesn’t necessarily reflect the type of driver. In my experience, Hank often seems to use one color for the first batch and another color for the second batch. The D4 driver type is more reliably indicated by the presence or absence of components on the spring side of the board, like a capacitor. FET+1 drivers are clean on the spring side, while linear D4 drivers have a few components visible.
