Backup for U22-XJ

Just a simple question...does the twrps on my u22 sd card work with u9. I.e could I make a u9h backup on the same card If I inserted it into the u9h and backed up what I have there?
 
hi Marty, this TWRP is not working after U22XJ update to V005, any idea?
It is working for me on FW005 so I really have no idea why it would not work for you?

Could other forum members confirm TWRP is working for them too on FW005 please.
 
after press and hold the reset button, it should go to the TWRP main screen but it doesn't, the tv screen just in blue screen, is this related to the display setting in FW005?
