[Jayinem]

I should have stayed on 6.72 been having a lot of crashes on 9.0.

The lower the firmware the better, since older firmwares also have exploits for newer firmwares, I'm updating my 6.72 whenever I have time

Goldhen 2.3 is the best for 6.72, you want 2.3 instead of latest beta?

Yes. Can you make it Goldhen 2.3? Or at least 2.4b16.2 to have Overlay SysInfo.

Try this one for older GoldHen, I'm also having issues with latest GH, it is 2.4b16.2 version

thank you very much @viggen66. so far this is the most stable host that i use. thank you

 

[viggen66]

I recommend refresh the hosts, as it has a small big change on thread handling

Hi

Just tried it (hard), but can't get it to work.
Deleted all browser data, typed url in, cached and after reopening browser always an instand kp with black screen.
Tried three or four times, clean from scratch. Also kp with rebooting between caching and reopening.

Then I tried the Webhost with new GH, cache works, reopening works, manual expl. and GH works and even autoload switch is working. But every second try the reboot and/or shut down kp's (white light flashing forever, pulled the power cord after 15 mins, long press power button worked too). Noted that GH settings take some time to show up in settings, after the notification shows up.

Maybe the host doesn't like external hdds' (PS formatted)?

Coming from an ancient PRB Leeful host, which was quite stable, only the webkit needed always a few times to run.

susi91,

That's very weird, I'm using these hosts, never had any issue, gonna check, but it doesn't make sense, gonna try to reload hosts on git, you probably got an older version of a jailbreak which had some issues.

Is normal to have memory errors when caching, no problem, but if memory error appears when trying to load GoldHen is better to reboot, to avoid any instability, but that memory issue is so rare to happen.

Try this one.

[susi91]

Try this one.

Done. Seems fine, works including resume from restmode. Tried it five times (with reboot/power off), no issues for now. Thanks

I got the previous JB version, which was prone to issues, , but absolutely no jailbreak is perfect especially when you need race condition to accomplish, only thing you can do is to dimmish the risk of happening.

Also this particular exploit is extremely hard to stabilize, for the time when the heap memory is corrupted, and the aftermath of it afterwards.

 

[susi91]

Yesterday evening two kp's in a row, just after the GH notification.
Maybe my Pro is somehow cursed lol

2 KP in a row? Seriously?
I have Fw 6.72 and executing the original JB exploit and GH I never have a single KP...

 

[susi91]

Yes, idk whats wrong.
Just installed 672 manual host from karo (GH2.3) to see if it's host related.

The date/clock is gone as soon as I pull the power cord, maybe thats the reason?

Could be... So that means that your clock battery died?.. idk , the last version of GH have a clock fix but you need to have Internet connection.. No sure because I don't need it..

Thanks a lot for your hard work on this jailbreak!
I’ve tried the page exploit you improved and it works perfectly for me with no issues or kernel panics
Honestly, it’s way better than any other host I’ve tried so far
Really appreciate your effort and thanks again

Yes I have made a change to the ROP chain of the exploit, the critical part of the exploit is not so dependent on race conditions.

Hi
Thank you very much for your efforts
But I have the same issue
( I tried the Webhost with new GH, cache works, reopening works, manual expl. and GH works and even autoload switch is working. But every second try the reboot and/or shut down kp's (white light flashing forever, pulled the power cord after 15 mins, long press power button worked too))

Maybe this issue because of the latest goldhen

And now new goldhen version is released 2.4b.18. 8
So if u could help me pls and tell me how to update and try latest version with your host
Or i should try old versions like 2.3 to fix this issue

Hi,
Didn't know of newer GoldHen release, the hosts are updated with new GH, try this fast host instead, is much newer code.
