I understand this topic has been discussed in multiple threads however I'm making this thread because I'm in need of some help. I've tried multiple methods but I've been completely unsuccessful in returning my phone to stock.

I S-off'ed with Sunshine (bootloader 2.49 VZW), and now I've relocked my phone. RUU's all fail for me..

I need to return to complete stock (locked, S-on) to send this device back, so any help would be greatly appreciated.

Thanks so much.
