I tried to update my long long used mii plaza, using fbi and shameless I got the usa update and dlc from there and something failed in the install but something did install, when I tried to start mii plaza it said my ext data was corrupted and reset, so I tried to copy the exa data from 00000218 from my sd backup from after finishing a9lh hax, back into that folder but it still says corrupted. I even tried to remove the exdata and save data and dlc for mii plaza and put my original data back in and it still fails. I am pretty sure I could re flash my nand back with decrypt9 and keep a9lh from end of step 5 (before I used shameless) and but the files back. But assuming that works I would assume I have reinstall every cia I installed since then (minus the mii plaza stuff) and re jksm the saves back in. Is there an easier way to fix this? Is it possible that simply re flashing the nand back will work as its the same nand and like id as it is now just that perhaps a system title got messed up?
