Cardputer COM Not Working
-
@ajb2k3 Yup, tried that button too xD
I'll with the multimeter if I can spot something wrong. If not, I will save some money for another Cardputer or something similar in the end of the year. I'm pretty sure that if I try to replace just the S3, I will mess with it. :( -
@hanktttop The screen is soldered direct to the StampS3 so you will need to be careful of that when replacing the stamp.
-
Guys, I found out how to make it on mac, where i had same problem. Cardputer off, connect usb cable to it, hold btngo and press btnrst - screen will go dark, release fingers, your in m5loader you'll see popup that its connected.
-
@doko178 Thanks for the comment, doko.
Still nothing even on the device manager. Now I believe I have tried every single button-press combination possible :D
-
@hanktttop What about pressing btngo when connecting usb? Works for me. I hope you'll solve it!
-
@doko178 Tried that some days ago. At least it prevents the cardputer autostart, but nothing about download mode. Thanks for the help xD
-
I posted a guide in the FAQ's
-
@ajb2k3 Thanks, still nothing.
Thank you very much to everyone who commented and helped, but I think I'll stop here. It took so many tries that some of the S3 pins are starting to bend, even though I'm careful when removing/inserting the chip.
I think I could end up damaging the cardputer if I continue with this stress on the components. I must continue my studies with simpler devices like the Portapack Mayhem until further notice.
Thank you very much for your comments, it is a very receptive community.

You can get the StampS3 separately (the core of the Cardputer) and experiment on that.
-
@hanktttop I have the same problem, my cardputer arrived yesterday, a follow all sugestions on this post.
Then I ask on discord channel hackingtroop about the problem, and their sugesto to try another cable, It's works. But one point of attention, the LED don't work as expected, anyway the cardputer enter on download mode.
Hold BtnGO, plug in o cable, and burn firmware. With the new cable, just plug and MM5Burner show pop-up about device found.
-
@has-oliveira who are you on the cardputer discord
-
@has-oliveira Tried multiple cables, no one worked. Did you used any specific brand?
-
@hanktttop have you used the firmware flashing method I posted in the forum?
-
@ajb2k3 Yup, I think this thread have (almost) all the possible methods of flashing the cardputer. Tried all posted here, the one on the FAQ, some I saw on other threads and Reddit (all very similar, just changing the order of pressing the buttons), some suggested on Github, etc. :(
-
Updating: After buying another batch of cables, I finally got a connection and can install firmware on the cardputer. For reference, it was this cable here. There is no specification, it is one of the cheapest you can find. With it, I just pressed BtnGo and connected. In fact, the S3's LED did not blink or light up at any time.
Thanks everyone for the comments, it was a long thread. xD
Maybe we can learn with types of cable doesn't work with cardputer and why they don't work after all. xD -
Might be a stupid question but did you make sure all the tested cables were data cables and there are quite a lot of charge only cables.
Glad you finally got it working. -
@ajb2k3 Yes, I tested the first time this was suggested. In fact, the first cable I was using was just for charging a portable gaming console. Then I tried a few more, inclund cables for smartphones, external drives, etc. And I tested then on their specific devices, everything normal.
No idea why the cheapest one worked on cardputer, though.

I'm glad you have it working now...mark this cable up as Cardputer saver cable

- Connect Cardputer on PC
- Open the Device Manager
- View > Show Hidden Devices
- Try Hold G0 and click RST until the USB JTAG becomes enable
