@philipdev1 ty for the update.
Remaining question : why nanos+ is not included ?
0xa00 --> except if there is a good reason you should have the same appflags like boilerplate.

please use the same flag as Boilerplate app flag :

"appFlags": {"flex": "0x200", "nanos": "0x000", "nanos2": "0x000", "nanox": "0x200", "stax": "0x200"},

ty @philipdev1 almost good
(but as I said, please remove NanoS)

- remove nanos from appFlags
- add support nanox, flex and stax
appFlags: 0x250 = 0x200 + 0x40 + 0x10
 - 0x200: BOLOS application
 - 0x40: multi-account
 - 0x10: only visible in developer mode
