Hacking M3 Lite will only work in GBA mode

[Tir]

I have an M3 Lite Perfect + Passcard 3, after putting new games on the card the DS refuses to boot it into NDS mode, only its GBA mode will work. I don't see the Passcard logo when I boot anymore. I tried:

- Cleaning the Passcard's contacts (bit hard to get to them though)
- Downgrading the firmware to an earlier version in GBA mode
- Formatting the 2GB Kingston Micro SD with the Panasonic card tool

I've had random issues before where NDS mode wouldn't work after putting the M3 in, but it fixed itself after taking the M3 and Passcard out, blowing on them and putting them back in. But I've tried that dozens of times and it's just not playing nice anymore. I've also had weird issues on some of these tries, such as the DS only booting with white screens (no health warning), getting past the GBA logo then freezing with a black screen, and even having a corrupt garbled GBA logo screen that it froze on. The poor DS must be getting sick of being turned off/on every 10 seconds.

Anyone had this happen or anything else I can try? Would it be the Passcard or M3 at fault here?

Thanks

Maybe the battery is dying. You may want to try changing it.

Well I unscrewed and opened up the M3, put it back together and... it booted, yay. Gogo dodgy Chinese hardware, eh?

the cart may not have been making full contact with the port in the ds
most likely the problem
