Where I can find the upgrade.scu for 1.63?

Thank you

It's a *.bin file, not an upgrade.scu file.

But I can't run a BIN file because the DS hangs after checking for SCU

If there is a .SCU the DS ask for upgrade, but if you upgrade or not the result is a blank screeen

Please help me

Using a *.scu file to downgrade will only screw things up even worse and possibly brick it more.  Try what PCRep on the official forum suggested.  Take everything off your memory card except sd_163.bin and bootup.  Press A and see if it works even with a blank screen.

After upgrade from 1.61 -> 1.70 -> 1.80 and 1.81 finally

Thank you for your help

Well, as surprised as I am that that worked, I'm glad you got it working.  I just remember a while ago people tried to use the 1.63 *.scu file for their Rumble or Lite carts (can't remember which) when trying to downgrade from 1.7 and it bricked their devices.
