downgrade hboot 1.57 to 1.40
I have an Evo 3d with Virgin Mobile and I desperately want 10.1
I am rooted, s-off, unlocked, and on hboot 1.57. To flash CM 10.1, you must be on an hboot version lower than 1.57. Is there a way to downgrade my hboot without reverting to s-on? because every link I find warns that you must be s-on.
I tried putting the PG86IMG.zip file with hboot 1.40 on my sd card and rebooting into bootloader, but I get an error message (see attached picture)
Please help, and Thank you in advance.
