Small correction: the "USB downloader" mode is baked into the SoC, and is what happens *before* u-boot (and what allows to download and execute a custom u-boot). There is currently NO known way of getting there. u-boot only allows you to get into fastboot mode, but that's a different story again. (Yes, I know this is all very confusing; it also took me months to wrap my head around it).

Although it might be possible with a special USB cable to trigger the downloader mode.

You will want to read all of the posts related to the above before taking the risk of bricking your device.
The former might be true - I'm too much of an idiot in electronics to be able to contribute anything meaningful. The latter is definitely true
