Device Info

Sinowealth Device: SH6890A
IC Label: Sinowealth SH6890AS
PCB label: BYK926

Variant:
https://www.yunzii.com/en-ca/products/yunzii-al71-mechanical-keyboard
They are almost the same (Yunzii has a version M71B I don't know what it is, but M71 and AL71 are the same), AL71 is rebrand name of M71. They use the same software (in AL71 software has a folder name M71) and since AL71 is flexcut, it's equal to M71v2 (v1 is 1.6mm non flex-cut). Reference

I've run sinowealth-kb-tool 0.0.10 several times and it returned nothing. Will try to run it on a Linux distro.

@rfcclub based on the HID dump, try using --isp_index 1, it should work:

sinowealth-kb-tool.exe read --vendor_id 0x258a --product_id 0x010c --firmware_size 61440 --isp_index 1 xm71.hex

Answer 3 · 2024-04-14T02:29:51.000Z

It worked, but I performed the read through an USB hub so I must plug keyboard directly to PC to make it works again. Read is OK, I am not confidence to perform a write yet since I don't have Sinolink to backup it first.
Also, the size of hex file is 168,972 bytes.
xm71.zip
Uploaded it here, hope it's useful.

Answer 4 · 2024-04-14T08:57:29.000Z

@rfcclub could you please read the bootloader portion of your device and update the device report template with it? (use the -b flag)

Also, based on the title, do you have two different devices? Do they have the exact same firmware? Eitherway, could you please open up another device-report issue for the Yunzii AL71, if you're able to test against it?

I am not confidence to perform a write yet since I don't have Sinolink to backup it first.

You can get a full dump of your device flash with the --full option, but yes, incase something goes wrong, you would need other means to restore it (sinolink).

@carlossless here is full dump with log

Actually I read from community AL71 and M71 are the same. Also I see they share the same software (AL71 also has M71 directory in their software). I can just try on M71 only.

Hope it helps to determine device information.

Answer 7 · 2024-04-27T18:28:17.000Z

@rfcclub thanks! the flag to read the bootloader is actually -b but I got the bootloader portion from your full dump and can confirm that its md5sum is 2d169670eae0d36eae8188562c1f66e8!

Answer 8 · 2024-04-27T18:40:05.000Z

@rfcclub interestingly I noticed that the md5sum for your first read (a123abac3a075fd4745cb6fd31a5324d) and second read (189f254a5715fba9ccd610890f5b90fc) is different.
The only actual difference is:
