Another piece of information I read on your blog regarding the dev mod certificate: when you remove the battery and restart, you successfully boot into dev mode. However, once the certificate expires, it reverts to retail mode. I’ve tested this twice on the series x devkit 1881

Thanks you for the details.
I have an Xbox Series X devkit prototype 1881 'Scarlett' (silver color), and the only things I can do are: configure the network, sniff, and perform offline updates. However, it requires connecting to Xbox Live, which I avoid

Guide and with a proper kit
xb@ing../devicedevicegroups.. ;)
Do you know how to do that with a proto kit 1881 who need to download the 4GB to finish configuration after a offline update and avoid the need to update on next boot and stuck on black screen ?
