A bit of searching and I found this thread

Can I downgrade?


On the third post it says:

PS: OTP stands for one time programming and it can not be changed. SEUS has changed your EROM CID to 52. So I guess flashing with CID49 EROM will help to have OTP CID = EROM CID = 49.
And my phone's
OTP CID: 49
EROM CID: 52
So that means I can downgrade?
