It has nothing to do with patience lol. I waited for a whole bloody day but it stayed at 0%. Reverted to 8.1 and then got 10536.1004. This seems to be the best resolve to this.
Nop I don't. :/Went straight on with my XL and our other 640's. Starting to feel like it's not far off now. Sounds like you may have a corrupt download. Does your phone say downloading or preparing to install? Phone recovery installed on my PC without any issues on 10 and 8.1.
You will probably need recovery to restore. Do you have another PC to try it on??
just re-read your first post. I think you may have internet issues. A hash problem indicates a corrupt d/l of recovery. I guess you've tried d/l again??
