Another one Ingenic X1000E SoC based DAP that I have is TempoTec V3. It's hardware close to HiBy R3Pro so I've collect the information too.

To get USB boot mode hold two buttons (in powered off state): 'Power' and 'Forward' (>>) (status LED will blink with blue color)
To get original recovery hold two buttons (in powered off state): 'Power' and 'Backward' (<<)

Looking in boot log you may notice that TempoTec V3 bootloader is based on HiBy R3II original one

--- Code: ---Board: R3II (Ingenic XBurst X1000 SoC)
--- End code ---
OTA firmware file is also managed by HiBy server.

Here is DAC/Audio related part of boot log.
You may note that board has physically GW1NZ-LV1 device but log is reffered to HBC3000/HBC2500. That is why I suggest HBC3000 is remarked GW1NZ-LV1.

Boot log in attachment. boot_log.txt is on stock firmware 0.0.4 with a lot of bugs and new_boot_log.txt is on latest firmware 1.0.

vitt13:
I also found that original firmware contains bootloader part UBOOT.BIN but it never flashed to device since the config file UPDATE.TXT does not have specific section. The additional section has to be like

--- Code: ---bootloader={
name=uboot
file_path=autoupdate/uboot.bin
md5=e1b0c012da7094b8a9686f15c9132ce1
}
--- End code ---
but it missing.
That discovery leads me to get dump of bootloader from the working device, compared to "new" one, and tested to flash 'new' bootloader.
So, 'new' bootloader does not work correctly (like odd LCD flash noised image on boot animation) and overwrite boot buttons combinations. It also has "Board: smsl_dp5 (Ingenic XBurst X1000 SoC)" in boot log so I do not think that is really bootloader update file for the TempoTec V3 device.
Here is original bootloader (mtd0 dump without OOB) that I got from the device (rename mtd0.zip.txt to mtd0.zip)
