Tested on 5 different Iphones. None had unlock pin code and all supported as per Cellebrite release. None of them worked with Checkm8.

Tested 3 of them on Checkrain and they all worked. Can only think Cellebrite rushed this release


i have exactly the same Problem...all Phones that i tested stay in DFU mode and Nothing happens… UFED still on "Explotiong"....now i will test Manual jailbreaking with checkrain


Are you definitely in DFU mode rather than recovery mode? (screen should be completely black and no iTunes indicator or graphics indicating a cable to plug in etc)
Set my second checkm8 extraction going in the late afternoon and also seems to be going fine (this time on an iPhone X).
Only pain in the backside was actually getting into DFU mode rather than recovery mode.

Yeah definitely im doing daily iPhone repairs, so this is not the problem but maybe problem is on my pc so i want to try it at home


My only other thought is; how long are you waiting? (maybe it is working but just not as fast as you expect?)
Even with the pin code the initial bit was quite slow - ie before it started copying anything at all from the file-system (I wasn't really counting but I'd guess maybe half an hour on the 7 and even longer on the X - maybe over an hour - before the start of the client screen with details popped up and started to copy).
Perhaps without the code it takes even longer to get to that point?


First of all Thanks for your replies :))
After 5 minutes i get error 34 from UFED, i will upload a Screenshot

There is an issue with data communication slowing down and dropping to zero at some point, so the extraction stalls.

It's in the logs, feel free contact the vendor Smile


I ran into this issue with the iPhone X (stopped after about 9GB worth). Support confirms they're aware and working on a fix.

I am also getting error 34 from UFED 4PC 7.28.2.8 after the checkm8 exploit fails after five minutes on an iPhone7 and an iPhone 6S Plus. iTunes reports DFU mode is good on both iPhones, so it's not my technique. I suspect the Windows 10 Pro version (1909) clean installed on my workstation may be the problem. What version of Windows 10 are you examiners running that succeed and get FFS extractions with those big DAR output files? I'm hearing versions 1909 and 1903 may be challenged.

I'm on Win10 1909 and it worked fine on one iPhone giving me a 28GB dar.
Waiting for the Cellebrite fix before trying the iPhone X again.
