DLPC3433: Custom firmware image for DLPC3433

Part Number: DLPC3433
Other Parts Discussed in Thread: DLPA2005,

Tool/software:

We have a custom board using the DLPC3433 and DLPA2005. We downloaded the firmware image FWSel_DLPC3433_DLPA2005_pm1_i2c0x36_v7p4p3.img from the TI DLP Pico Firmware selector tool and are able to load the firmware onto our flash chip, and the DLPC3433 is able to boot off of it with no issues. However, we need to set the start-up LED Current to be significantly lower than the default in the image file (<750mA). When we try to update the flash image in the DLP LightCrafter Display program we get the error "Flash Image Update Failed: Unexpected Error. Contact TI Application Engineer". 

Is there any way to get an updated flash image with the start-up LED currents lower?
