The timebomb was pushed back from September 3, 2019 to September 3, 2024 in the most recent updates to the relevant flashcarts. These changes fix issue #1715 .
More detail:
The "R4iSDHC 20XX" carts were updated from 3.9b to 4.0b, and I figured out the new timebomb date by testing it on my own r4isdhc.com flashcart.
I don't own any r4i-sdhc.com carts, so I can't test it. However, I found a [store page](https://www.r4wood.com/home/16-r4i-sdhc-3ds-rts-card-for-3ds-all-systems.html) for this flashcart explaining that the "Latest time bomb for 1.85b kernel is Sept 3rd, 2024." The latest kernel version before 1.85b was 1.84b, but for some reason the current guide references kernel version 1.87. I think this must be a typo because I couldn't actually find any evidence that there ever was a 1.87, so I believe 1.85b is now the latest.
I hope my changes are received well.
