Not sure where to ask this, but here's where I'm at....
- Downgraded my 2DS to 9.2.0-20U successfully
- Dumped NAND with Gateway ULTRA 3.6.2
- Set up dbs
- Used ninjhax (latest version) to get to miniPasta, then installed FBI CIA to sysnand
- Dumped SD card
- Formatted emunand
- Copied SD card dump back except for NAND dump
- Downloaded rxTools 2.5.2, generated firmware with the python script, and used http://dukesrg.no-ip.org/3ds/go/?rxTools.dat to access emunand
- Updated emunand
- Unlinked sysnand
- Re-setup dbs on sysnand
- Installed menuhax on sysnand and set up ability to boot to CtrBootManager automatically
I can now get as far as CtrBootManager, but I am unsure of how to boot to rxTools 2.5.2 from there. The default boot.cfg points to /rxTools/sys/code.bin, offset 0x12000, but I do not have that file (I assume it's a future version of rxTools). I attempted to access /rxTools.dat both without an offset and with an offset of 0x12000, but both take me to two black screens and hang there indefinitely.
I am still able to get to sysnand and homebrew menu, and using the link above to get me into rxTools still works. However, I would like to be able to get in without an internet connection so I can delete all internet connections from my sysnand to prevent accidental updates.
This is the last step before I'm all good to go, it seems. What am I missing? And furthermore, if the issue is that the version of rxTools I'm using does not support launching from CtrBootManager, am I somehow able to update rxTools and keep my existing emunand?
