I was playing a game with ez flash omega, it was working fine, I turned it off and turned back on after a few seconds, now i always get Gameboy screen, no nintendo logo. The cart isnt booting.

I tried to check the crystal with multimeter in continuity mode. No beeps between any of the 4 pins.

Can it still be the crystal?

Also does the crystal has to be exact 24.54545 mhz, or can it be rounded off like 25mhz or 24mhz will also work?

Thanks

Yes, it must be the exact number.

I got to say, although it was interesting, I wasn't much of a fan with your guy's EZ Flash V back in the days. But I do love your dedication and support of the product.

Appreciate seeing repair/diag info. Not a surprise to see some BGA issues on these thin boards.

I only have accesd to aliexpress, as other options have shipping charges almost equal to the price of the cart itself.

The closest option available is 24.576mhz. Will it work?

Im confirming beacause it takes 30 days for the package to arrive.

If 24.576mhz wont work, is there any other option left for me?

Thanks

Yes i have tried, still havnt got any response, and chances seem slim. I bought this from Aliexpress as well.

Ill try the local cellphone parts market , if indont find it ill order 24.576mhz.

In the mean time ill get the main chip reflowed (flux and a little heat) by a local guy here who repairs ps4.

Its just been a couple of days since i got my EZ Flash. I started having random hangups with RTC feature and some random cart restarts a couple of times.

I bought the EZ-FLASH OMEGA DE through a dealer in South Korea.
But my cartridge is showing 'Read S71 ID Error!!!!'

I wanted to exchange the product because it was difficult to refair.

A dealer in South Korea says to me :
"You can contact this forum and exchange the product,
if the ez-flash representative guarantees it."

So I would appreciate if the person in charge could reply quickly.

Hello EZ FLASH omega asked to update V00 version to V05 version. i clicked refresh and then it asked me to reboot. I turned the GBA off and on again. After that, when you turn on the GAME BOY without the Nintendo logo.

any quick fix to repair a (destroyed) card reader on the board? (the grey housing above the contact pins to hold the micro in place)? pretty sure the connector pins still work

What is the course of action in the event of #9 but without the safe mode errors? I've initiated contact w/ the dealer, but wanted to continue troubleshooting. Thoughts?

Impressive damage.

That would be situationally dependent.

If it is one of the readers with an eject function but everything else intact you could probably bodge it with some tape to hold it in.

Anything else would depend upon the damage. All the EZFlash gear with card readers onboard have been soldered on so removal, repair of any traces if damaged (be it by the damage already or removing it) and replacement then gets to be the main way, unless you want to go complete cowboy and solder the SD card into the flash cart (if it is not one of those fancy wireless SD cards then will be very annoying to update anything, especially as most DS slot management tools won't work or are extremely ill advised -- random bricking, and chances are you don't have DS homebrew capabilities on it to run a FTP server or something).

@EZ-Flash2 keep getting S71 read error on Omega DE, hot air reflow worked a few times but now it doesn't work anymore. I reballed it and reapplied it and still S71 read error. Any recommendations on where i can get a replacement S71 chip?
