Ok... i'l try to explain my situation the best i can. My friend has a CFW o3ds running arm9 + luma 3ds, E region. And i have a stock 3ds U region. I've been trying to change his modded 3ds region to be able to dsiware downgrade my stock 3ds but no luck so far. I followed Plailect's guide and managed to change region to U, but the problem is... i can't connect to eshop it keeps showing error code 005-5964 (or something like that, didn't write it down, but it's not that error code for wrong region setting). The guide says it should work, and i've been trying to get help from the wonderfull people of 3ds hacking discord channel but they also don't know why it wont work. So... what are my options ? i heard that this kind of data from eshop stay tied to secureinfo_A. Is there a way to make sysnand fresh only keeping a9lh of course then do the region change and maybe make it work ?
