Using the python EDL client is where I get a little lost. I can install it no problem, though I see two install methods on the github, I assume either or works. I would then reboot to EDL, but not sure what command I should use after that, I've seen a lot of tutorials use a .elf file, in this thread I've seen reference to a .bin file, am I supposed to rename that? I do not see the command needed to get the boot.img file on the github page under UFS or emmc, nor do I see a command to do a complete backup.
I guess my other option is to get the update from:
http://data.onyx-international.cn/api/firmware/update?where={"buildNumber":0,"buildType":"user"," deviceMAC":"","lang":"en_US","model":"Poke3","subm odel":"","fingerprint":""}
But
https://github.com/Hagb/decryptBooxUpdateUpx does not list the Tab Ultra, seem like obtaining a string isn't too difficult, but in either case it would be nice to get a full 128gb backup using EDL in case things go wrong.
Any help appreciated!
