I was running into the same problem.
(6s, iOS 13.3, Ubuntu)
AHCI was disabled in my bootloader (grub).
Make sure AHCI is enabled in your BIOS and your bootloader.
It worked for me afterwards

i had the same issue iphone7 ios 12.4 on xubuntu , tried again on kali and it worked

Same! It seems that the issue is having an iPhone 5s

Same exact issue.

Also, it wasn’t responding even to button combos to escape dfu mode. Starting to restore the device broke it out of the mode.

Strange question, do you have a secondary iDevice?

I did manage to successfully jailbreak my iPhoneSE using Arch and the checkra1n binary.

I initially thought that the reason I was successful was because of all the usb port swapping that I did, but I’m thinking it may have had something to do with the fact that I connected and disconnected my other iPhone (7) after the failed attempt to jailbreak my SE.

I then ran the checkra1n binary again on my SE with complete success.

iPhone 7 13.3.1
iPhone SE 13.1.1

Strange question, do you have a secondary iDevice?

Unfortunately not.
BTW Did everyone notice that almost everywho here`s got a linux kernel version 5? Latest ubuntu comes with 5 kernel. Will try to do it with old Debian. However, a lot of people successfully done it on 18.10. And Arch seems to be affected too.

edit: kernel 4.19 have that issue too.

You have to write „sudo apt-get install checkra1n“ in terminal.
Of course also disable Passcode and sign out from Icloud before trying to jailbreak

Of course I installed checkra1n properly.
Tried it, but same thing. It has something to deal with USB controllers. Maybe. Or it`s just a bug.

Quick update: got to Download Mode: when it stucked I quickly pulled cable out and in. But unfortunately gets stuck at «allocating static region for rdsk». Will research further

Same device, same error, don’t know why

Same issue, I’ve tried multiple cables, three types of usb ports, all USB-A on Xubuntu 18.04LTS
I installed the current package, and tried both the GUI and CLI.
Included all the relevant info from the kernel log for the usb device and the whole process of using checkra1n.

kern2.txt

usbfs: USBDEVFS_CONTROL failed cmd checkra1n rqt 128 rq 6 len 65 ret -110

Yep, seems that’s the bug itself. My friend did the same thing with iPhone 7 on Xubuntu 18.04, jailbreak was successful and that strings never appeared in kernel log. Now we need(not actually we, but checkra1n devs since it’s closed source) to find the bug. But unfortunately the fix will probably take a long time. By the way, on Mac running Catalina latest version works.
edit: long time means at least a couple of days.

Disable your passcode that worked for me

Unfortunately it doesn’t work for me.
Tried it on my friends pc with AMD platform, means on X470 chipset and still this errors on my iPad. However my friend successfully jailbreak his iPhone 7.
edit: strange thing that it works on my Mac Mini. So that bug is stick to Linux.

Try this i was stuck trying all this other crap 3 days myself. This worked first try 4 separate devices different combo of cables and ports. All on 13.3 from iPhone 7, 8+, X, iPad air2 https://github.com/foxlet/bootra1n/blob/master/README.md

That would do the trick!!!!
Thank you very very much, I was lost…
Tried with different pc, different cables, different ios, downgrade…
iPhone 7, 13.3

Did it work for you?

…

Yes truff1ep1g it worked perfectly,

I commented just to thank you and leaving a note hoping that will help others
I saw a lot of posts of people in similar situation

I lost my previous jailbreak status (unc0ver) due to a unaspected reboot
I update from 12 and was having «_irec_handle_device_add: failed to get string descriptor» error… no idea why except something not quite correct from my
previous jailbreak (i didn’t have the opportunity to do a RootFS)

Thanks again

Sweet. After i spent
A few hours adding repos and tweaks on my phone and iPad. I went into every thread (almost every thread). And posted that at the bottom. I just wanted to get it to those who appeared that they were having the same issues as me. Also I was hoping to steal away some viewers from these two guys on YouTube that were getting so much clickbait adding new tutorials claiming to have fixed the errors. New videos everyday. And
You could read the comments and see the same amount of people having the same problems so obviously they weren’t fixing anything Anyways I should shut up. On my way to my step son so to speak. Otw to his 22 birthday lunch or dinner or whatever. I’m the car with his sister and my headache. Take it easy. Keep a usb handy in case u need to reboot. Ha.

…

Keep a usb handy in case u need to reboot

Already have…
Installed a problematic tweak,
Used the method once to go in Safe Mode and uninstall the tweak
and a second time to re-jailbreak
works perfectly

Now I’m satisfied… I take a break in installing things, enjoy my phone…

Thanks

Right. I here ya. It has been quite a few years since I had been on iOS much less jailbreaking. Not since the iPhone 6. I switched to android while back and liked the open source nature of it. Man nothing’s like an older nexus or note rooted with Kali nethunter installed. So easy to copy and paste Lazy scripts or run Ruckey on that thing. WiFi security forces the most part is a joke. Everywhere u scan the network names are all “myspectrumWiFi90” etc. and u know if they left the name they left the password the same too. Right off the sticker on the router knock em off wait for them to handshake again and hello airdump what’s this u have for me? Encrypted passwords? My neighbors like porn you say? And playing Fortnite? kids stay away from next door!

Same issue on a PocketBeagle with debian 9 IOT for Beaglebone. However, sometimes it does work.
Updated to Debian 10. Now I get this log:

https://pastebin.com/QAyFmEba
Number one was successful, number 2 (rebooted after first attempt) hangs.

Same exact issue.
iPhone 8
12.4.1

Also, it wasn’t responding even to button combos to escape dfu mode. Starting to restore the device broke it out of the mode.

just use unc0ver ios 11 to 12.4.1

This is a known issue. #984

Marking this as duplicate of #984 (this issue is older, but the other one is more generic and thoroughly documented).
