You may check v70 documentation to see if it says something about it.

V70 makes big changes in autoprovisioning format... You can find various documentation for infos about it at the above link.

Interesting, I have a T22p stuck on, and they will not use any firmware on the official update page, even in tftp recovery mode:

Edit: It turns out I was updating the firmware wrong. It must be named t22.rom in your tftp root folder.
