Hello everybodys, This would be my issue which I am at a loss to figure out myself. I had an unmodded system which for some reason I would get to Health and safety screen press A and black screen. I discovered maintenance mode and decided that perhaps an update to the system was needed, so I upgraded it to 4.3. The problem still continued, so I went back to maintenance mode and attempted to format the Wii. I left the thing on for the entire night and nothing seemed to happen. Turned it off, when back into maintenance mode discovered it had deleted all the downloaded titles but did not fix the problem. I then started to look into modding, got bootmii and priiloader. Now when i update/install priiloader it seems to work fine, I can turn it off, get past the H+S warning and look around the system menu normally, even go into the channels with no issues. I could even turn off the Wii and go back to the system menu with no black screen. But if if load a channel and then after using it wish to go back to the system menu it goes to a black screen and my original problem seems to persist. I though it was a mail brick and so used Det1re's Mailbox Brick Fix to try and fix the problem, which again only seemed to help until i exited a channel. Although this never happened when i attempted the fix " 6. End the app and restart the Wii. You will get a message that your Mail account is broken and will be restored." I never received any message about the Mail account being broken. In conclusion: I have: 4.3, Bootmii as Boot2, priiloader, can enter maintenance mode, updating priiloader will temporarily fix issue as will Det1re's Mailbox Brick Fix. Tried: Formatting before and after modding, Det1re's Mailbox Brick Fix, deleting useless channels(news, whether, mii) I am new to this whole modding thing so I may not know too many acronyms. I will try and give as much information as needed. Thank you for any assistance.
