I've restored my stock nandroid backup and flashed stock recovery, but I can't get the OTA to install. My M9 is from T-Mobile, and it has S-off. Here's what I get.

E:missing bitmap oem_unlock_bg
(Code-1)
E:missing bitmap oem_unlock_bg_yes
(Code-1)
E:missing bitmap oem_unlock_bg_no

Any help with this?
