What do you mean? Did you flash s17 with s19 firmware?

If I'm right why not flash it again with s17 firmware through an sd card?

You can also use brainsOS firmware if ever the above does not work then flash it again with stock firmware.

I watched the video and that looks like an S17 control board, so where does that S19 come into play here? anyway, the green led is constantly on which is bad, it has to blink a bit when booting, and the boot files in this control board are missing/corrupted.

You need to go to https://shop.bitmain.com/support/download and download the TF file under the name > sd_set_default_password_enhanced_0527_S17.zip, follow the flash instructions.

Hi, I have a sj 19 pro like to put braiins on it and they made me switch to the s17 c55 controlboard, because I had amlogic my asic, for that reason bought that.

I did the unlock and then put the original bitmain firmware, s19 j pro and then it never detected the ip and the 3 lights never came on again.

mikeywith, I have tried that file and it still does not work..

Actually, I can't understand what you trying to say would you mind using a translator instead and paste it here.

If you have a control board of s19 and it's broken and you buy an s17 control board and you are trying to flash it with s19 firmware there is a big possibility it would brick.
If you have a bad s19 control board you must replace it with a control board which only use for s19, not for the s17 control board.

Take note if you have a fake SD card with fake volume the firmware that you are trying to flash is always corrupted so better use an authentic SD card Samsung or Sandisk.

Did you try a hard reset? you can do that by pressing the IP report button while the board is powered off, keep pressing the button while using your other hand to reach to the 12v cable and plug it in, keep that IP report button pressed for at least 10 seconds, the control board should blink, and that would signal a successful hard reset which could bring it back to life.

Hello, I tried everything, but I have not been able to fix anything. The Chinese company where I buy them send me another 3 new ones, the ones that do not work I still have them here, I can send someone a free one, send me private if you are interested to see if you can fix it and inform me to do it.
Thanks

Are you sure that you successfully flash them?
I guess the control board is fully bricked what I think is that flash the control board through the serial port if you don't have a serial port cable you can jump them just make sure to jump them RX, tx, and gnd.

There is a full guide about this you can follow the guide from the link below.

I would like to suggest remove all hash boards and fans from the control board and test if you can find the IP. If not then your network might have conflict IP sometimes Bitmain send units with duplicate mac address if you can able to replace the mac address it might fix your issue.
