[1.1.2OTB] Can we use testpoint method for BL4.6/1.1.3(accidental)

Becuase if i recall, the first news about any 1.1.2/1.1.3 posted by TAmobile being unlocked was 1.1.3, and he did it the hardware way... so i accidently (intentionally to unbrick) updated my 1.1.2OTB to 1.1.3.. is there any way to downgrade BL the testpoint way?

i think you have to wait for the 1.1.4 or 1.2.0 update/secpac

from geohot blog:
"You need to have a 1.1.2 4.6 phone for this to work. If you upgraded to 1.1.3, have fun waiting for 1.1.4!"
