old thread, but i just went through this process and i've got it working.
using latest Go4 4.3.3-frida.ipa
assuming you've got super-impactor downloaded/installed and running with your ios device plugged into your computer... click on device, you'll see "install from IPA" - that will let you select your ipa.
some recommend keeping wifi off for this part - i think it did help me to do so.
you'll have to use an apple id and password... some use app specific password, but i found that too much of a PITA so i just put in my regular old id/password since i try not to use any of that ****** icloud crap and i just DGAF (let's face it, nothing is going to stop anyone from compromising your apple id as it probably has been compromised by a massive hack more times than anyone can count).
then you attempt to install... i think it errors out once or twice and even freezes at some point, but it will eventually work in several minutes. basically it signs the untrusted app.
when you enable wifi.. open up itunes... select your ios device and select file sharing.. select the DJI app that was just put in there and you drag all the files into the documents window (files unzipped from the dji-ios-frida-tweak github... i just put them all in there).. and SYNC
THEN you gotta go into settings on your ios device, general : device management ... and you'll see under DEVELOPER APP your itunes id.. you click on that and VERIFY.
then i opened up the app and ran it like regular old dji go app... but it has a popup for config.
reason i'm in here looking this up for the mavic air is... i enabled boost mode and i'm wondering if this actually helps for anyone?
i'm using an amplified antenna (alientech pro 5.8g) and i can't tell a difference.
i mainly set this up for a mavic pro to use in 1.5w 2.57ghz, but wondering if it even helps for a mavic air?
