What firmware version is your ezflash at? I know the ezjr had issues with a specific hardware revision of the gbc which was fixed in a later software release.

Wouldn't explain it not working on the GBA, though. Is your GBA modified with a backlit screen as well? Are you using rechargeable batteries?

Not about a battery mod, are you using rechargable NiMh AA batteries or alkaline? If alkaline, what brand?

 

[EZ-Flash2]

what if you boot the card with CGB connected with a power supply(no battery)?

After I watched the video several times, I found that the problem should still be in the contact. After the last plug in. the card is working fine without any issue.

You may check the the metal contact in the socket, Some may be deformed or lose their elasticity.

I dont have the power supply and i re-clean all the parts, other games works fine. After the video the EZ Flash Jr don´t work at all (GBC and GBA). i think the flashcard its just broken and i need a refund.
Thanks.

dirty cartridge connector could also halt booting, and show a garbled Nintendo logo.

It could certainly be a faulty flashcard, but do try using a fresh pair of quality brand alkalines (Duracell, Energizer or similar - avoid budget brands from your local discounter or similar). While I haven't had issues with rechargables in the past, I know that some people have.

Flash carts generally have a higher power consumption and rechargable NiMh batteries only provide 1.2V of power as opossed to the 1.5V alkalines provide.

I run a 3.7v Li-Po battery in my GBC, with a TP4056 charging circuit, and no power issues. Even has the backlit IPS mod.

Thanks to all for your time, im gonna return the flashcard.
