hey few questions, how big microsd card can i put into this player? will it lag if we exceed like 16GB or something?

Max 32GB. Can't help you on the lag, as I'm not using any microSD on my C30 yet nor do I plan to exceed 16GB..

got some problem with this cube!!!
failed to boot and ask me to format it....how to format it?

Firmware for the C30 can be found at their official page. I'll give you the link to the said page.
- v007.020 here
- v007.021 here

Also, the default firmware is v007.020. While .021 is newer, the only person that I know to have used it said that it doesn't have extra BBE presets i.e. VIVA, MP etc.

Never flashed my C30 before, so can't help you with the installation part...

EDIT: Just downloaded the firmware. From the given software, it looks like it's as simple as plug-in the C30, run the software & flash the device..

thx for helping me out....
already try to flash it...but still cant boot

You probably have tried this, but just to be sure, does pushing the reset button do any good?

p/s: Just a reminder, only something with the size of a paper clip can properly click the reset button. Pen tips can't.

yay! yay! all c30 purchases are posted today to all buyers, i cant wait!!

well..i already try to reset it..but its still failed to boot...some1 plz help me

Google results are no good; ran out of idea..

Hoping that more experienced Gummy/C30/N2 users could help. Final resort, warranty claim?

Have you tried the quick format method? Plug in the C30 and right click the drive and click on format. The quick format option should be there.

After reading through a thread named Nationite N2 - tips, tricks and how to use UPDATED 28th FEB, it's said that the latest N2 firmware is the same as C30's.

Also, I found this: Nationite N2 Firmware restore guide; A guide from mp4nation on flashing an N2. Perhaps with this you can try flashing your C30 with the given, proper steps.

MrJinggles : already test this method..its said please input drive

Agnaem : i will try this method bro..if success i will inform u XD

The Windows format method is not very reliable to be honest. Try this software, I use it to format all my external memory cards and Sansa Fuze.

If Agnaem's method doesn't work, give this a shot.

So, is there any diff. regarding the Sound Quality. Some said that the SQ is even better .

my batch of C30, which came in like last week or so, are with the 021 firmware, and all BBE presets are available, including VIVA, VIVA 2, MP, and BBE Headphone 1 - 3, User 1-3

btw the 021 version firmware changelog:
fix for BBe volume shrink when volume reaches "27"

version 20 changelog:
FM volume fix
fix custom BBE being defaulted when restarting c30
fix display when switching from FM to Music becomes "NOR"
fix charging displayed when connected to PC

Thanks for sharing!

Also, I've read somewhere that says when .020 is ejected from windows, it'll show the USB connected screen as usual, but with .021, whenever it's ejected, it'll leave the USB connection mode and enters charging mode. Difference is, you can use the C30 while in charge mode unlike the USB connection mode..

It'll be great if you would confirm it.

I gave it a shot just now, 021, but after eject, its still on the usb connection mode... btw, you made the c30 userbar? nice one

Pls give the link where it says that 0.20 when ejected from windows will remain in usb mode rendering it unusable.
I'm on 0.20 and have never experienced what you just said.
So 0.21 will remain in charging mode when ejected from windows? hmm interesting.

Added on May 13, 2011, 1:38 amfunny that your 0.21 is behaving differently from the 'norm'....... shouldn't it revert to charging mode once ejected from windows?

I see.. Btw, yeah I did. Thanks!

@wongpeter
Just to be sure, you mean yours always gets to charge mode after being ejected? Nice. Which version of windows are you using?

It is somewhere in the mp4nation's N2 tips & tricks thread that I mentioned earlier. IIRC, someone said that latest N2 and C30 firmware's allows the charge mode after being ejected, hinting that previous doesn't. Though, IIRC, what I get from the same thread is that with older firmware, some say it works, some say it's not..

My C30 with .020 never went to charge mode after a safe removal btw. Not that it actually matters.

does c30 support music sorting by artist/album etc?
