Nothing to do with erom,sets before 12W14 are old and can be done via tp,sets after 12w14 cant be done this way, simple.

Actually in some rare cases, phones after 12w14 still have old security and can be unlocked through tp, and some more rare sets before this date may have new sec...

But this is really not common.

[koperta4512]

By 2011 - the old security
From 12w01 to 12w10 - usually old security
From 12w11 to 12w16 - usually new security

Error conectando terminal: Preloader check timed out
Note: Devices manufactured after 12W10 have no support for TestPoint operations
Proceso abortado. Tiempo total [17 seg]

New security - If you need unlock phone buy NCK code.
