Backdoor for sideloading apps in Mango will enable more powerful ChevronWP7 Labs [Homebrew]

Back in June when "Mango" was first making its rounds, one of the first things we noted with regret was the inability to sideload pretty much all homebrew apps created up to that point. What would happen is you would try to load the app and be greated with "Error 0×81030120". Reason? It's technical but "Mango won’t officially support the deployment of custom applications with the ID_CAP_INTEROPSERVICES capability flag".


Even more of a bummer for the proposed ChevronWP7 Labs, which would be limited to sideloading only apps that don't modify the registry--that is, apps that can't customize the OS at any level.

The good news though, as reported by ChevronWP7 member Rafael Rivera, is there is a way around this. XDA member“Heathcliff74” discovered that if your MaxUnsignedApp value is 300 or higher, you can remove the limitation and sideload the app. This gives devs an easy workaround for re-enabling Homebrew apps (it's been speculated that this "trick" was for MS employees and OEM partners).

Rivera goes on to state "The suitable pairing for this hack is, of course, ChevronWP7 Labs". That's of course, some great news for all of us.

  • The first thing that comes to mind is Yeah!
  • "The suitable pairing for this hack is, of course, ChevronWP7 Labs"Not more than marketing imho. It should work fine with the official unlock, the LG MFG registry or the old Chevron unlock.Anyhow good news :-)
  • "The suitable pairing for this hack is, of course, ChevronWP7 Labs"Whatever. Go Heathcliff74!
  • The fact that this borks the 3G settings has me worried, but it seems to be an easy fix. I was certainly not pleased when MS announced the restriction for Mango. I'm even happier that this fix comes first for Samsung devices.
  • Yea, it sounds like a cool hack but, LG and Samsung only. HTC owners need not apply (does not work on HTC devices)
