General Firmware and OS version questions

How do i find out what firmware i am on?
Can i update the OS without updating the firmware?
How do i update the OS?

 

OS and firmware version shown in "device info" menu
yes, you can update os without firmware update
you can update os via "update os" menu

 

Any way to recover from a bad OS update? I was trying to update to OS v15 from v8, and my cat got excited and accidentally pulled out the power cord, so it just boots to a blank screen.

 

try press A+B+C or A+B+C+UP, before power on, keep butons until reserve OS copy will be loaded (should start immediately after sega copyright screen).

 

Would using a 6 button controller make any difference? I've tried both combos and both give me the same black screen.

 

console show sega copyright screen?

 

Yes, it does show the normal copyright screen, then is black after that.

 

can you remember which default OS version was installed on your cart in the beginning?

 

I got it during the assembler group buy. I think it was v5 maybe?

 

I remember that some old carts have bootloader which mey not load reserve OS by some reasons. i will try instal same bootloader on my cart and check how to run reserve OS. i will let you know soon

 

Thank you.

 

give me more info about your system please. MD/GENNY? 1/2? 3/6 button joy?

 

It is a Genesis Model 1, High Definition graphics. I'm using a 6 button 3rd party controller as that is all I have.

 

i have solution! problem in joypad initialisation. joypad not inited by bootloader, so need to int joypad by some game.

I have tried it repeatedly with sonic 2, vectorman, and aladdin and so far no luck, I still only get a black screen. I'll keep trying though. Also, is there a specific way i need to pull the cart as sometimes it seems to reset itself.

EDIT: I did manage to get it to work! I updated with the update-os module to v15, which took no time at all. Before when using the built in OS upgrade in the toolbox menu it ran for a few minutes and didn't have a progress bar or anything. Should it take that long?

EDIT 2: Thank you soooooo much KRIKzz, you have made my birthday so much better! I appreciate all of your hard work.

 

so all ok?

 

Yes, everything is working fine now. Got it updated to OS v15, and it works normally if I power it off and back on.

 

good. i guess your cat will stay a live now

edit: i like cats

 

Yes, she seems quite happy about that as well LOL

 

Oh the trick to getting it to work was A+B+C+Up, just A+B+C did not work. Worked on the first try when holding Up.
