First, I flashed my NANDmin.bin into my emuNAND so that I have a 9.2 firmware in emuNAND whilst a 11.x in sysNAND. I did not delete the emuNAND after installing a9lh. I am about to region change my emuNAND (from US 9.2 to JP 9.2) by following this guide: https://github.com/Plailect/Guide/wiki/Region-Changing. Of course with common sense, I should do everything with EmuNAND, rather than messing up with the present SysNAND. What I am not sure is whether I could get access to e-shop in light of the following circumstances:- 1. I remember that my US N3DS console (be it sysnand or emunand) has connected to internet before, but I cannot recall whether I created a NNID for my previous sysNAND (i.e. the present emuNAND) (probably not). What I am sure is that I created a sysNAND in my previous emuNAND (i.e. present sysNAND). Here, the Guide provides that: "After this process, only Old 3DSs and New 3DSs which have never accessed the eShop before will be able to access the eShop after creating a new NNID on their new region. Region changed New 3DSs that have already accessed the eShop on their original region cannot create a new NNID and access the eShop on their new region!" So, does it mean that I could never gain access to esShop even I have a valid JP Secureinfo_A from another JP console simply because my console has connected to internet before? 2. I had a JP console (A9lh installed of course) which I rarely play but sometimes I would mess around with it on eshop (so I am not prepared to abandon my JP console completely) . I created NNID on this JP console. What I am prepared to do is to extract the Secureinfo_A from the JP console and to inject it into the emuNAND of my US console. On the other hands, I may still constantly use my JP console and do things online on eshop. My question is, (a) can I create another NNID with the secureinfo_A obtained from the JP console in my US emuNAND and so to get an access on eshop in my region-changed US emuNAND? (b) would I get ban from sharing the Secureinfo_A with another console? Certainly I would not log on eshop in both US and JP console at the same time. Can this avoid a ban on sharing the Secureinfo_A? Any thought or help would be much appreciated as I am gonna region change my emuNAND first whilst awaiting you guys' replies. Thank you.
