This has been my experience. I attempted to decrypt the downloaded update.upx file via the following URL:

http://firmware-us.boox.com/865e7836a4d6da883e52ed2822f60b9c/update.upx

Which was derived from:

http://data.onyx-international.cn/api/firmware/update?where={"buildNumber":0,"buildType":"user","deviceMAC":"","lang":"en_US","model":"Nova3","submodel":"","fingerprint":""}

And it failed to decrypt after updating the DeBooxUpx.py file in the cloned Hagb / decryptBooxUpdateUpx Git repository with the following boox_strings variable sub-object, which was acquired after following the instructions How to get the strings:

'Nova3': {
	"MODEL": "Nova3",
	"STRING_7F00500": "VUkFew9KjsE54uQMSZI+S2tT1RRckT/vKkfiFFqImxi7",  # settings
	"STRING_7F00501": "VEsMcHw88MpwOByhT7zqNhRFTQcruVMqhdllIlY6T+6f",  # upgrade
	"STRING_7F00502": "TGlcNi8npJe4EHxzOKbCXakJKDssoRldHueY5OGl"       # local
}

I am more than happy to assist with rooting my Nova 3, but I lack the experience and knowhow to do so. What is the appropriate programmer file to use when attempting to backup the boot/recovery images for the Qualcomm® Snapdragon™ 636?

Thanks in advance!
