Consistent Crashing on iPhone 6 (Does not produce logs)

[cjnott1999]

Upon jailbreak of 4k device (iPhone 7,2) consistent, and to my current knowledge, seemingly random crashing of what appears to be coreduetd along with several unknown crash logs. Attached is the crash log for coreduetd.

Do you happen to have an Apple Watch connected?

@AppleBetas Yes, yes I do. Are there known issues with apple watch compatibility? I saw something similar in another issue, but didn't seem to be exactly what I was experiencing.

[6e757275706f]

Yes there are many issues with the apple watch. Crashing apps. Blank icons, Delayed notifications, and now this

[AppleBetas]

There are a few known issues, but those don’t appear to be as severe as this one. I also have an Apple Watch and iPhone 6, with coreduetd crashing. Since coreduetd does do a few things regarding Apple Watch, it could be partly because of it.

[cjnott1999]

I am attempting to replicate the issue and collect more logs now

[karboN90]

Not just with Apple Watch. I don't have a Apple Watch. And the problem still exists. Everything works fine but there is sudden crash and reboot of the iPhone

[cjnott1999]

I appears the crashes i am experiencing don't produce logs at all. Unknown crashes. all around

[tamer3030]

same here Iphone 6+ random restarts specially when I connect my Bluetooth headset

[silerh7]

Yalu crashes when I open safari or messages for a little while, it's somewhat stable everywhere else

[msamuel002]

i wonder if he fixed any crashes on the iPhone 6 in the newest commit (10 minutes ago). He didnt say anything about it but

[tamer3030]

I will compile the current commit and check

[kpwn]

Please test last commit. Closing this for now, reopen if issue persists.

[liudayu]

Issue persists. After I press GO in the app, most of the time device produces a "coreduetd" log then reboots, few times it resprings and back in jailbroken mode.

[nullpixel]

@applebetas is also having it still happen

[kpwn]

oh i'm tripping. i thought this was my iPhone 6 is not stable issue. sorry, reopening. haven't looked into this

[nullpixel]

Also, it looks like a permission issue, and I think it's linked to the watch issuee

[liudayu]

This is the coreduetd log file. Log.txt

[nullpixel]

Ooo that looks like a permission issue even more now

[nullpixel]

coreduetd handles stuff like watch connectivity and handoff for the record

[kpwn]

Is this only happening while in jailbroken mode?

[nullpixel]

Yep

[liudayu]

No, when you reactivating your jailbreak by pressing GO, sometimes it fails and then reboot, this is the only log it produces.

[nullpixel]

I tried to start it manually, and it crashes almost instantly

[cjnott1999]

It appears from timing that coreduetd actually crashes before the phone itself reboots. Then it produces an unknown log.

[AppleBetas]

I also was just able to trigger a crash by switching to Safari on my Mac (therefore activating Handoff).

[blobbyblo]

After the latest commit I have expierenced 0 crashes or bugs. I'll try and stress test it to see if it crashes.

[liudayu]

It still crashes for me, just got a panic log and reset counter log after the latest commit

panic-2017-01-30-024234.txt

[kpwn]

Ew, a SError with version set to MarijuanARM64. Are you sure you got the last commit?

[kpwn]

Anyway, that's a KPP failure. Had it happen due to inconsistent branch prediction. At least not a unknown memory access fault!

[liudayu]

Yes I did git-pull before I opened my Xcode. I will delete everything again and do a fresh clone, then see how it goes.

[karboN90]

@bobbysnow You sure the latest commit experiences no crash at all ?

[cjnott1999]

Major kernel panic on clicking "go" with latest commit. In Xcode console the jailbreak doesn't reach completion. no logs generated.

[kpwn]

This is not 100% reliable, and expected. You should have a 50/50 chance of the exploit working.

[cjnott1999]

@kpwn Ah, still getting consistent crashing, again, no logs. Crashing happened quicker than last time upon reboot into a jailbroken state

[andrewwiik]

@kpwn rebooted, almost got to pressing the mail app before it crashed, iP6 10.2 Edit crashing is happening about 5 seconds after reboot into Jailbroken mode. I do not have a apple watch paired to the best of my knowledge.

[malhal]

After todays commits I successfully jailbroke my iPod Touch 6th Gen (log output), thanks can now get on with updating my tweaks. SSH working.

[callum-99]

Also getting a random panic with the same panic log as @liudayu (iPhone 7,2 10.2). But other than that its very stable

[justinoboyle]

Latest commit randomly panics as well (AFTER jailbreaking. Like, swiping pages on home screen, open an app and it will randomly go black and reboot). i6.

Also, Cydia just crashes, but SSH works.

[msamuel002]

Yea at least luca knows what the issue is. Hope its an easy fix

[chashmeetsingh]

works on iPhone 6

[msamuel002]

@chashmeetsingh no crashing at all? how lol

[chashmeetsingh]

did once -> rejailbreak -> works fine now

[msamuel002]

hmm, i havent tried it out since they said its still not fixed. let me try

[raj0x29]

rejailbreak won't work/// rebooted 4 times and try it still does not work

[justinoboyle]

@chashmeetsingh Try doing a few things on your device, it will probably crash in a few seconds.

[chashmeetsingh]

hmm right did

[msamuel002]

ohh

[andrewwiik]

I think it is important to reboot inbetween a failed patching that causes crashes, is this correct? @kpwn

[msamuel002]

lol so basically luca just fixed the 5S and accidentally left the 6 undone? (which is fine idc)

[kpwn]

I am unable to repro this over multiple rejailbreaks.
