Hi all,

i'm Matthias from Switzerland and i'm new here i'm an electronic-engineer and i repair all kinds of Electronics and iPhones on Chip-Level.

I try to downgrade the 06.15.00BB science a few days. i sucessfully flashed the old Baseband (fls and eep). But i can't run it. (normal, i know)

where is the version-value stored? in protected area of the XGOLD or in Intel-Flash?
when i flash an older BB with bbupdaterextreme, are some bytes skipped? (bacause fls-eep mismatch displayed)

who knows more?

BR Matthias
