Hacking SC DSOne SDHC - Blank Screen

[ttrand25]

Hope i could get some help. I got the new SC DSOne SDHC last week with a 4GB Kingston Micro SD. I downloaded the OS and follow all instructions to set it up. It's been working great for a few days now till today. Whenever I play & finish a level, my DS would become blank on both screens when it changes levels or when quitting a game. I've tried all tips and tricks from this forum (i.e. change SD Speed, Save Size...), but still have the same problems. Please help. Thanks

Try the self-test. When you boot up the DS, hold L+R+UP while the health warning disappears. Then press A until you get to the part where it's counting through some numbers and letters. If it completes properly, you're safe here. But you're in trouble if you get an error like:

psram error!
cell error! addr=00000000

It's kind of bad because the paper trick doesn't have a very high success rate. I've tried it myself without success.
