checkra1n 0.11.0 hangs or crashes on userland boot

[ghost]

Tell us about your setup: What iDevice are you using? A: iPad 5th Generation (WiFi) Board Config: j71tap to be exact On what version of iOS is it? iPadOS 14.0 (18A373) What version of checkra1n are you using? Latest 0.11.0 What is your host system (OS version? Hackintosh? VM? etc.)? An old 2010 white MacBook on Catalina 10.16.5, same error on my HP Laptop running the latest version of Ubuntu 20.04 LTS. How are you connecting to the device (USB-A? USB-C? Apple/3rd party cable? Through a USB hub?)? Original Apple USB-A cable, tried every USB 3/2 ports. Aswell tried using different cables. What are the steps to reproduce the issue?

1. Connect the iPad to any usb port
2. Run checkra1n as usual
3. When checkra1n says "Booting" the device shows the checkra1n logo then it reboots to a normal apple logo. ...

What do you expect, and what is happening instead?

I expect it to continue showing the checkra1n logo until the device has reached SpringBoard, Instead it reboots and the Loader doesnt get installed and I usually get 2 errors from this.

1. usbmuxd (Error -79)
2. Bootstrap Timeout (Error -20)

I have tried to jailbreak with the safe mode option on but the same thing happends. Everything worked fine on 13.7 and below.

Does the issue also occur if you tick "Safe Mode" in the checkra1n options?

Yes

Any other info, error logs, screenshots, ...?

^ Same thing happen when I use the CLI version.

[Catta1997]

Same thing with same device (iPad 5 wifi), noticed that the reboot happen afterL2TP domain init complete but I don't think that is related because sometimes crash on IOMFB use_scaled_brightness: doit=0. I have tried a "clean iOS install" but with no success

[Siguza]

Can reproduce.

[noob698]

I also noticed the same thing happening on old iPadOS 14.0 beta with iPad (5th Generation Wifi)

[jeffry2berdugo]

Same here :( on the same device

[Epicvoid986]

Yea, ipad 5th generation (cellular), tried on Mac and Windows with checkn1x, can reproduce, both error code -20 and -79

[noob698]

I guess this is happening on all iPad 5th generation

[shoyrock]

I have the same problem it was working fine on 13.7 once I tried version 11 everything stopped working

[leofe4]

I have the same thing happening to me on my ipad 5.

[mmm286]

Same problem

[noob698]

Hopefully this gets fixed soon. Everyone who are using iPad 5 will experience this crappy problem

[BorisYeltsin]

Hopefully this gets fixed soon. Everyone who are using iPad 5 will experience this crappy problem

and iPad Pro 1st gen

[Sandwhich253989]

Same problem here I have tried 20 times with Linux windows mac on my ipad 5th gen

[clove7802]

same problem with my ipad 5th gen on ios14 and ios14.0.1. hopefully this gets fixed soon.

[michaelmantz]

Same here, ipad 5th generation cellular, on my iphone 6s works fine on ios 14.01

[jazzmaxx]

Any idea when this will be fixed? Closing the issues doesn‘t fix it. I understand that duplicate tickets need to be closed but also this issue should be worked on.

[trn1ty]

Glad to hear I'm not the only one with this issue, and that it's known to the developers.

[TOTALMICHEL]

pretty sure that they are working on it, but its a FREE project. they don't get payed to do this, so even it takes a year or more to fix, we should be glad that they took some of their valuable time to give this awesome tool to us.

I have the same issue here using ipad pro 9.7 inch ios 14.0.1... It worked perfectly with ios 13.5.1 but now it's not I v tried it for 30 times in the past 3 days (I change the cable.. Used the method were u unplug the cable before booting ect.. until I given up.. i thought the problem with my iPad now its clear to me.. I hope it fix soon my son is killing me with his noise lol.. Thanks for this great tool developers

[Vitteliustin]

Same problem here with ipad pro 9.7 :( hope there will be a fix soon...I've tried macOS Linux Bootrain CLI mode, nothing works...

[noob698]

Yeah same with iPad 5th

[iosfabian]

Same error on iPhone X iOS 13.7

Tried all given solution options

Anything else I can try?

[noob698]

I don’t know. After this problem gets fixed, your iPhone problem might also be fixed. The checkrain before 11.0 got released worked on my iPad when it was running on 13.7. Just turn untested thing on and see if that works

[iosfabian]

@noob698 tried all this simple things No solution

[victorcrane]

iPad Pro 12.9 First Gen ios14 After jailbreak error -20 stuck on CR app booting screen and weird part is when I connect to the ifunbox its says jailed

[noob698]

@victorcrane does the checkrain application there though?

[victorcrane]

@victorcrane does the checkrain application there though?

no CR app in springboard

[noob698]

Shit

[iosfabian]

Is there any update expected in the nearly future?

[Ismael903]

Hi i got the same problem error code 79 in the ipad pro 9.7 with ios 14 and use the last checkra1n, does anyone know the solution? I think we have to wait for the developers to work on it, I would like to support them with some donation or some incentive since they work not for profit and we benefit from it.

[modaifallah]

Saaaame here, tried ubuntu, mac, ra1nux, terminal and gui, gives checkm8 logo and text, then panics and reboot midway. Ipad 5th generation Wifi.

[noob698]

So many participants. Must be a major problem then

[Medlk]

Omg I m still trying every solution I see daily with no results except a headache.Did anyone tried the Rainusb version... Plz if anyone find something replay

[Ismael903]

I'm trying the same thing every day, and I can't find the solution. We will have to wait, at least in ipad pro 9.7 first generation with a9x chip does not work, the usbmux error 79 jumps let's wait for it to be solved soon ... greetings, let's not lose hope

[abacus0101]

I thought i did something wrong.mhopefully next release of CK fixes this otherwise no jailbreak

[abacus0101]

These guys that work on this devote alot of time on it. The only issue I have is if they are going to release,a new jailbreak for 14.0 ect and then say it works on original ipad pro’s, it means no one really tested it fully before releasing it. Thats the only criticism I can see. Now we are all at the mercy of the checkra1n developers. It is after all a beta and they have not updated it yet. Hopefully the next version will add the checkra1n loader app to the devices and we will get a full,jailbreak

[ShawnTimez]

To be honest checkra1n beta 0.11.0 just seems broken.

I dont think we are waiting on anything particular for ipad 5th gen. Its running the supported processor. The exploit is there.

I tried running beta checkra1n 0.11.0 when it first came out when my device was still on ios 13.7

The results were checkra1n beta 0.11.0 never would successfully jailbreak the device not even on ios 13.7 however checkra1n 10.2 worked everytime.

I'm convinced there is a small error that is causing a huge issue in the new version of checkra1n and I tried it on multiple devices (beta 0.11.0) and it never worked on anything I tried it on old or new.

Verdict checkra1n 0.11.0 was rushed and untested completely. Im surprised anyone has gotten it to work on anything because i have not.

Also would like to reference this post. https://github.com/checkra1n/BugTracker/issues/1744

Could it be related? Or are ipad 5th gen users just screwed here?

[Medlk]

@ShawnTimez I am no expert in jailbreaking.. But I wanna give this information it may help.. Whenever I tried to jailbreak using 0.11.0 it shows always the error 79 wmand when I use version 0.10.2 it always give me error 77 (for iPad pro 9.7 inch ios 14.0.1 via bootrain) I changed cable/pc always the same problem

[witsadmin]

Same thing happening with my iPod 6th Gen. However, 0.10.2 works perfectly

[Tmarkr]

is it the A9 chip??? is anyone having this issue trying to jailbreak iPhone 6,6S or the 1st gen SE???

[hermes814]

sane problem here, iPad 5th on ios 14.0.1

[Vitteliustin]

Still no update! :( ? Hope that someone's working on it and our problem isn't ignored by the Chrckra1n guys...

[isaamrgt]

Hi , i found it today , try this https://youtu.be/XlQpZebt-OI

[Siguza]

Yes, we are working on the issue. And it's not something you can fix on your end, it has to do with our early boot setup.
Unfortunately we'll have to go through a lot of code and test on many device and iOS combos to make sure we don't break even more, so it won't be a quick fix. :/

Thanks for the update. I was wandering if you guys would be able to post/releases a beta/Canary version so users who brick there Devices trying to use version 11 to jailbreak they are devices are are able to downgrade back to a previous version we use an SHSHBLOB, I was on 13.6.1 when I tried jailbreak he’s in the latest version of Checkra1n it end up breaking my device that’s why I had to update to the last version of iOS, if you guy having problem getting the update out without breaking other things I understand I don’t know how to code So I have no leg to stand on when it comes to that but at least remove the version that are currently not working off the main website so that users gonna stop working their device by attempting to jailbreak with that version

[TOTALMICHEL]

For me, checkra1n 11 works on iPhones. It just fails on iPads. (Even old iPads like mini 2 on 12.4.8)

[Medlk]

@Siguza thank u for the replay bro, you're doing a great job

[hermes814]

Important! Code :-79 Cause analysis

A user whose code: -78 and-79 could not jailbreak appears，A conflict caused by the wrong installation of a plug-in or a file is almost certain, or is there some other hardware problem? Take a look at Settings----privacy----analytics and improvements----analytics data----panic-XXXX-XXXX-XX-XX-XXXXXX.ips my question： After I swiped the Checkra1n code to about 80%, the iPhone started automatically，The [you may attempt to enter no-substrate mode by holding vol-up during boot(starting with Apple logo until boot completes).] approach doesn't solve my problem.Since I did not install Cydia but rather installed the software via SSH, even the no-Substrate did not solve my problem. Library\LaunchDaemons This folder contains the plist file installed by me using FILZA software via jailbreak,such as com.matchstic.reprovisiond.plist,It will associate the usr\bin\reprovisiond file, As a result of installing these two files，After I swiped the Checkra1n code to about 80%, the iPhone started automatically，Then the jailbreak failed.Of course,Brush into the checkRA1n code after I choose safe Mode also failed. Please.Can Lucas or your team create a new pattern?Bootstrap jailbreak bootstrap without loading all files in the Library\LaunchDaemons folder. After success, SSH channel port 44 ROOT will be granted automatically.Users can write the command script from Workflow (Shortcuts) to uninstall the files themselves, or install iTerminal software to uninstall the files via SSH channel port 44. That's the only way I know so far. In addition,ReProvision, installed via SSH channel port 44 (not cydia, but deb parsed packaged IPA files), had no unusual problems for the first week.In the meantime, I've rebooted the iPhone and then jailbroken it with Checkra1n, and everything seems to be fine, with no unusual problems.All of a sudden one day, I don't remember how the iPhone was rebooted, the first time I booted the jailbreak through Checkra1n, the desktop still had the checkRA1n icon, just like now, the SSH channel was closed, and I forgot to click systeam inside the checkra1n icon to clear the jailbreak environment, but that's later.Boot the jailbreak desktop with checkra1n on the second reboot and the checkra1n icon disappeared, and I was unable to install Cydia, nor was There a Succession plug-in in Cydia to flatten the system. In September 2020, I heard that Apple added a SEP security processor cache control, which caused problems in the connection between CPU and peripherals. I wonder if my problem is related.

Tell us about your setup: What iDevice are you using? iphone8 D20AP On what version of iOS is it? 13.6.1 What version of checkra1n are you using? ubuntu，mac，ra1nux，terminal，gui，CLI， checkra1nLinux 0.10.0-0.11.0 GUI and CLI，when I entered DFU mode and plugged in USB cable, the Iphone would start up automatically, so I did not try. Ra1nMacUSB is based on the Mac environment usb drive system.0.10.1-0.11.0 GUI and CLI，when I entered DFU mode and plugged in USB cable, the Iphone would start up automatically, so I did not try. checkn1x-1.1.2 0.10.1-0.11.0. What is your host system (OS version? Hackintosh? VM? etc.)? Ubuntu, Windows and usb sticks,Usb flash drive system based on Mac environment. I have change the different configuration of Windows Intel CPU start by U disk. i7-3770k E3V1231 i5-2300

5. How are you connecting to the device (USB-A? USB-C? Apple/3rd party cable? Through a USB hub?)? Orginal charging cable. What are the steps to reproduce the issue?

8. ... What do you expect, and what is happening instead? Checkra1n Jailbreak successfully opened SSH channel port 44, and Then I used the Linux command to remove the conflicting files over SSH channel port 44. An SSH channel is actually not open. Does the issue also occur if you tick "Safe Mode" in the checkra1n options? Yes, it still happens! Any other info, error logs, screenshots, ...? I suspect this has something to do with Apple fixing the LPE bug in 08Tc3wBB. When 08Tc3wBB indicated that Apple had fixed part of it, Apple added a SEP security processor cache control, causing problems in the connection between CPU and peripherals.

The following is my network disk link, because the network environment is special, so in the form of ZIP packaging released to the forum, please Siguza watch, thank you. My English is not good, I hope you can understand my description.
