dreaded 507 or 567 screen
I went through OS recovery He..
Wiped fine but had fatal errors trying to install OS
(I must have tried 10 times in 5 hours)
Then, I made sure all old OS's were uninstalled
(Still have the exe files if I want to go back)
I had the USB cable on my laptop docking port, moved it to a port directly on my laptop.
Deleted all the OS files of the OS I wanted and reran the OS exe install
Did the DOS version of the loader and it finally worked.
Thanks all!
Now I have 4.5.0.52 on my curve...
