Here is the Scepter8_Tablet_v01_20220915 it's zipped

Off topic question lol does anyone kn

Maybe this was answered already. My XDA app logged me out and I did not get any notifications. Thought it was quiet to long lol. That failure at 20% if it says unexpected end or something like that it's because the file is either not extracted properly or just corruption while attempting. The .zip file can be extract with really anything to reveal the .IMG file. You need to extract that carefully into the proper .fex formatted files. Can't recall the name of the tool but it's listed in this thread. If you don't have the files extracted the encrypted.fex files won't read properly and will have data lost so they will be invalid. If you extract the .zip and .IMG file and the result is .IMG files. It's the wrong format and not a valid image. Almost all failed attempts lead to files named 01.boot.img when the IMG is corrupt. If you get file names as boot.fex vbmet.fex super.fex those are correct and you can rename them boot.img if you want. However the boot fex will work as expected. As for ATT unlocking. Try the att website. They have been easier to work with on network unlocking. Even Verizon will network only unlock any device as long as you have it for 90 days on a account. Even if you end up not paying it off. As long as you kept it good for 90 days. Automatically the new devices unlock the network. Just swap the device out on your plan if your changing service provider due to the bill. Don't lock the device to your bill. However that may not be necessary anymore with the resent unlocking policy. Vzw doesn't bootloader unlocked willingly anything tho. ATT however will even unlock some prepay devices and most postpay that are not att brands. Takes about 48 hours to get an email back with a response and the unlock.
