[Question] Regarding the FW update key #11

Open morgenstern09 opened 1 week ago

Hello,

Could there be any correlation between the update key for A100 and these parts from the update info XML (which I can't see because I may not know enough about these things)?

Update key: o0W0mihblfJOPtNQPN8Pc2hLKiTROL5MVERN9OmmkkMNZO2P XML info: eaid:ENC0001 daid:HAS0002 digest:31e23cc8f971db11e61a4fca52a5ffad

If there would be, then maybe this could help obtaining the update key for NW-A306 and the other Android devices as well.

Between different regions that info is different, while the update key is for sure one and only, no matter the region - so the conclusion is that there is no correlation...
