So I was screwing around with the TWL_FIRM version to see if I could make my R4itt Pink card to work with a O3DS (sysNAND 4.2.0-9U, emuNAND 9.0.0-20U) I have rxTools installed, loading it from MSET and booting to sysNAND to install both the DS FLashcard Time Warp CIA and the TWL_FIRM CIA. The title ID and versions I downloaded are: 0004013800000102 v1489 (TWL_FIRM) 0004800F484E4841 v0 (FlashCardTimeWarp) I already had the FlashCardTimeWarp.cia installed and the Blue Gateway Card worked just fine, but since that is the one I use in my N3DS, I wanted to see if I could make the pink R4itt I had lying around work since that one didn't boot with only the Time Warp cia. So I went ahead and deleted 0004013800000102 (didn't check the version I had of that one, damn my soul) from NAND using FBI, and installed 0004013800000102 v1489 into NAND in its place. Rebooted the 3DS and... now the DS games give me an error at boot. "An error has occurred. Hold down the POWER button..." I already tried deleting 0004013800000102 each time and tried with EACH of the versions that I saw compatibe with the USA firmware, which are: v1489, v2565, v4625, v5681, v6704, v7762, v8817. ALL OF THEM GIVE ME THE SAME ERROR! Dx What can I do to fix this problem?! I am sure I only deleted 0004013800000102 and no other CIA.
