Bitmain A113D Amlogic (S19 90TH) issues after update

So, I've got this Amlogic A113D Control Board that’s part of the Bitmain Antminer S19 90Th. Here’s the deal: I tried to do an update using a Pendrive, and now the board just won’t respond. I was using this update: https://i.postimg.cc/7LwbtL9X/Vinish-1.png And my Pendrive looked like this: https://i.postimg.cc/VkbHZfvS/vanish-2.png The update went through, and the green light came on, saying it was good to go. I pulled out the Pendrive and rebooted, but now it’s like the board doesn’t recognize the Pendrive at all. The light that usually indicates it’s connected isn’t lighting up. The board isn’t booting up either. I only see the green light on the network card, but it doesn’t connect to the network, can’t get an IP, and still doesn’t read the Pendrive to reinstall the Bitmain software. Has anyone dealt with something like this? Is there a way to do a hard reset?

The image you posted above is very blurred I can't seem to read where did you downloaded the firmware. It seems it was from vnish-firmware.com but this website seems fake no one mentioned this website before that this is legit. The firmware you downloaded bricks your control board. Isn't that the original firmware should have come from asic.to? If the OTG to USB flashing doesn't work anymore then you can try to flash the control board through a TTL cable you can find the guide from this link below. - https://www.zeusbtc.com/articles/asic-miner-troubleshooting/1082-recovery-method-of-miner-serial-port-virus Hope this one will work.

Thanks for the answer. I just bought a USB TTL to try this. There is no other way. I downloaded the image from the website below. I don't know why the host downgraded my image resolution.

I do not know what this is. :-( Best regards,

Let us update here if USB to TTL would work. About the source where you download the firmware I never heard of this domain there is also vnish.net I do not know if these sites are legit but would you mind to download the firmware instead from asic.to for safety purposes? Or better download the stock firmware from Bitmain.

I was wrong to download this firmware. A big mistake. Yes, I can put any firmware you recommend. The board only turns on the network light, nothing else. And it doesn't read the pendrive, it doesn't even turn on the pendrive light, as if it had no power. I already bought the TTL cable, I'm waiting and it should arrive tomorrow. I bought this model with drivers: https://produto.mercadolivre.com.br/MLB-2200958817-1-x-cabo-ftdi-usb-a-para-ttl-rs232-pl2303hx-4-pinosnf-_JM?quantity=1 I looked at how to upload the OS using TTL and it doesn't seem to be simple, but it isn't complex either. I am going to try. Thank you for your help, BTC UP and the machine stopped... :-( I'm an enthusiast, I bought 30 S19 90Th. But I still don't have that knowledge in terms of maintenance. Best Regards,
