increasing the success rate for iphone7

[d386538]

iphone7+, never had a success jb

• tries 30 time each time before going for yalu
• I tried beta 3 and 4
• disable gps, findmyiphone, passcode
• airplane mode
• Things here: https://www.reddit.com/r/jailbreak/comments/6gze38/tutorial_extra_recipeyalux_iphone_77_jailbreak/
• Clean reboot the device, wait for a couple of minutes, start extra_recipe, wait for 5 seconds or so, then hit "go".

b4 never say "failed, reboot", just simply close the app.
b3 it just hangs over there or reboot

I can't think of a thing that I haven't tried.
Does extra_recipe generate a log that we can see what's happening?
I suppose figuring out this will definitely improve the success rate.

i am on the same boat 2 hours now.i am trying to get it working and i get always, Failed,Reboot on ip7+ 10.1.1.
I don't know why, until yesterday i had a stable jb and today is fcked up.did more than 50 tries and i didn't get anything else than Failed reboot or some strange kernel panics. Mach portal sent me immediately on jb mode at the first try tho.i don't know whats going on.

Same steps taken on my iPhone 7 + 10.1.1. Some successful but after I've tried the multiple extra_recipe builds you can watch the console in Xcode. But now mach_portal always works. 4 days now no panics. Also uninstalled anemone.

If it says "failed, reboot" you should really reboot. I can't think of a thing that I haven't tried.

Seems like extra_recipe fixed mach_portal. Nice!

@greenZebraQuest Honestly, I never had mach_portal last more than several hours (same hardware), so you're either lying through your teeth or are a very lucky person.

@d386538 most likely no: increasing the success rate is a very difficult task, it not guaranteed to get close to a significant % and probably not worth my time. For the record, I get it working in 3-5 tries on average, worst case 10 tries. Granted, that is without Xcode -- that means after you install the app with Xcode, disconnect and try as is. You don't need the Xcode debug log, unless you are actively developing extra_recipe. Another hint, try increasing nports for your device to something insane (like 80000) or lower it; it's a gamble.

• Having the i7+ disconnected

1. int nports = 40000; app closed no matter what
2. int nports = 80000; reboot the phone no matter what

• Having the i7+ connected

1. int nports = 40000; app hangs
2. int nports = 80000; reboot the phone no matter what
3. int nports = 77500; app hangs

This is what I get. Don't know if you can come up with something.

Note: I always had to reinstall yalu b3 after trying out extra_recipe.
Otherwise, my phone will just reboot.
I assume some yalu files was replaced with extra_recipe?

If anybody could chime in on the actual failure reason, that would be much appreciated. (cc: @xerub)

I think I've read somewhere, that the reason why the failure where the phone reboots happens, is a race condition of the exploit vs the KPP. If that's the case, why don't we launch a beefy background thread to heat up the CPU enough to make KPP slower, thus increase the potential success rate?
