Repeated crashing when executing jailbreak

[apach3guy]

"I read the issue posting guidelines."

iPad Air 2 (iOS 10.2) yalu102 beta 7. Cannot enter jailbroken state after upgrading cydia and mobilesubstrate this morning. I have repeatedly launched yalu102 (more than 10 times now) and each time iOS crashes and reboots. I relaunch yalu, hit "go" and the iPad crashes and reboots. Over and over and over.

Last time I launched Cydia I had a "Half Installed Package" warning; however, I did not forcibly clear as this was not recommended. Not sure if this is related.

I have deleted yalu102 and side-loaded again with Cydia Impactor to no avail.

would you please provide the full .log

[apach3guy]

I cannot. The size exceeds the maximum enforced by github. I can provide this additional log which may prove useful. Reset counter event:

I have the same problem on iPad air2 , qwerty needs to fix the reboots but if you open 6 random apps then try and hit go it has about 95% success rate to rejailbreak, but I keep getting random reboots and I've got nothing at all installed

@apach3guy from looking at the log, it looks as if the kernel is crashing because it notices a buffer overflow, and it specifically notes yalu102 as the thread that caused the panic so i can assume that yalu is bugging out on your device. ill try to find the bug in the code. keep trying to resign yalu, check the hash, and redownload the .ipa and see if that fixes it. ;)

Just keep trying. Eventually, you'll get there.
