What are the steps to reproduce the issue?
- when attempting to jailbreak error 20 shows up midway even with checkra1n in safe mode
on iPad error states: Found old-style rdsk! Detected corrupted kerninfo! Enabling usb done! pongoOS
2.RESTORED iPad and setup as new with same issue
- attempted other versions of checkra1n all crash midway other than latest version ...
What do you expect, and what is happening instead? jailbreak should complete
Did you see a popup on the device stating it entered "Safe Mode" due to an error?
yes and it did with same issue
Does the issue also occur if you tick "Safe Mode" in the checkra1n options?
Yes
issue still happens when safe mode is ticked!
Any other info, error logs, screenshots, ...?
Checkra1n:
error 20
on iPad error states:
Found old-style rdsk! Detected corrupted kerninfo! Enabling usb done! pongoOS
It appears a few people I know with the iPad Pro first gen have the same issue. Please checkra1n update your app and website to help!
I have updated the iOS just to get the new jailbreak, as the website states, it will work with my device and it doesn’t. So now I have lost my jailbreak. Please help!
I have a suspicion as to what it could be... here's a debug build of Pongo:
Could you please unzip that, then run checkra1n on the command line with -k path/to/PongoConsolidated.bin?
That should print a bunch of hex values on the screen, please take a photo of those.

hi there
I've received the PongoConsolidated.bin file. When I try to unzip that file it states it's unsupported format. Unsure how to run checkra1n on a command line. can you help in explaining the process please?
Open Terminal, Drag the checkra1n app into the window (that should auto-paste its path), then append /Contents/MacOS/checkra1n and make sure there is no space between the part you dragged in and the one you appended.
Then hit space, type -k, hit space again, then drag PongoConsolidated.bin into the window and hit enter.
The GUI should pop up at that point.
@Siguza I tried to load the modified Pongo, and here's the result (iPadOS 14.4.2):
/Contents/MacOS/checkra1n
thank you,
this is what i get when following your instructions.
Hi here, Same device, same release, same results ! It worked last week with ios 14.4.2 and checkra1n 0.12.2 I updated to ios 14.5 and 0.12.3 with current issues I then came back to 14.4.2 but still getting the issues mentioned in this thread with both 0.12.2 and 0.12.3...
I completely wiped my HighSierra iMac, and I was able to get 14.4.2 working with checkra1n 12.2.

Great! Strange to see that the issue is coming from macos😕 Furthermore, I'm having this issue with Ubuntu as well.
@Siguza is this the output from your command when trying to load the modified Pongo?
Ok, I messed up the previous build. Try again with this one:
So follow the same instructions as before and send you a snapshot?

Any updates?
same here also...
same thing here on 12.9" A9X as well, I'm running Big Sur (Thunderbolt to USB A Adapter>USBA-LIghtning) but also have a Catalina Mac ("Good ol'" straight USBA) and am willing to test.
Weird because I seem to recall seeing that 14.5 was preventing jailbreak from working at all via the checkra1n exploit(s), then I saw specific support for the new 0.12.3 beta and just like a robot, went and upgraded from 14.3. I hope this isn't permanent, but I dunno, seeing nothing but 00000000s where someone expected a bunch of hex readouts is never going to fill me with confidence haha
Thanks for bringing this up people. The more people sharing this issue the more the developers can see and help.

I guess any of us using ipad pro a9x has the issue, or is there somebody with the same device able to jailbreak??
Marking this as accepted.
I'm pretty sure the issue is that the A9X iBoot overwrites a part of our payload on 14.5. That would also explain the 0% success rate.

Great to see that you seem to understand the issue ! :D Would that mean that you already know how to fix it? I would be happy to help if you don't have an a9x close to you !

Does this mean we will have an update soon?
Experimental build. Please try this:
1st gen iPad 12.9" user here. Unfortunately, it didn't work. It went right from DFU mode to a normal boot with no sign anything was actually injected.
Experimental build. Please try this:
Hi Siguza
didn’t work for me either. After I follow the guide to DFU, within seconds my iPad starts up as normal without installing anything.
I confirm, it reboots normally after DFU without going to usual jailbreak state. No ssh root possible
