I have followed a guide to debrand or flash a dead lumia by renaming the files and creating the folders 817. When i create the folder rm-817 the NCS product tool didn't detect it for me so i went with the rm-819. I've ranamed the files to my product name and everything went through find apart from the error before it started flashing under recovery mode. Signature verification error.
Has anyone encountered this before with the lumia 800?? If so please guide me to a work around, any help at all will be much appreciated.
