Can I use the old firmware to fix the boox's fastboot command?

[Eternalcat]

I sent my Tab10CPro back to the boox to fix the boot issue. They helped me write an older version of the firmware , the version is 3.5.1. And I found the old firmware can stell use the "fastboot flash xxx".

For now, I am already make an full backup for the firmware Ver.3.5.1, Is that possible to keep fastboot command work with newer firmware? Like use 3.5.1's boot.img and xbl.img with 4.0's super.img?

Probably. You tell us.

Personally, I can do without fastboot completely.
There are two things that it can do more conveniently though than other components.

• Boot images directly without flashing
• Swap _a and _b slots.

yes, it's possible, however, you must make sure you flash the images matches your device, and proper recovery/abl images

Could you please explain how to boot images without flashing? Thanks.

It depends on your fastboot supporting it.
I believe that they have been getting rid of all that stuff on Onyx.

adb reboot bootloader
