Hello everyone, I just registered here after finding this website come up alot in my Google searches to try and solve my problem, hopefully by making this thread someone here knows why I'm not being able to upgrade the card. So I just bought a 2nd hand DSi that came with this R4i card (the one that just says v1.4 without the WiFi logo): From what I can tell this is a legit card, with Truth Inquiry label. This being all new to me, and me being stupid, I updated the Firmware on my DSi to 1.4.5E and ofcourse the card stopped working. I searched online alot and from what I could gather I should be able to update the card to a newer Firmware and Kernel to work on a 1.4.5E DSi, so I borrowed an Old DSi with version 1.3E, put the updated files I got from the Official Website ( http://r4i-sdhc.com/downloade.asp ) in it. So the card works on the old DSi, I can boot R4i (shows up as a Star Wars Lethal Alliance), and boot roms, but when I go to the upgrade Screen instead of getting this: I only get a screen that shows the Current version as "Support Model: NDSL, NDSI 1.40", there's no New Version, Info or Upgrade Button displayed, and I've checked the flash file is present. If I try to use the Wi-Fi engine icon some times it fails to connect, and when it connects it fails to request login to server with the error "Erro code: -1071" I already tried download older versions of Kernel/Firmware (R4i V1.42b, V1.67b) I found online but all have the same behavior, no upgrade button is displayed. Does anyone know why this is happening? Should I be able to upgrade using a DSi with an old firmware? Thanks in advance.
