When this happens not even itunes works again. I have atleast 4 devices that are now bricked because of this. I suspect it has something to do with jailbreaking

[SmiVan]

Seems to be a similar issue to #316, which was closed without explanation. Might also be related to #333, #174 and #66, which all show the same ERROR: Unable to connect to FDR client (-2).

At least some of these seem to share the property of being run on previously-jailbroken devices, and some of those seem to be non-bootable or non-itunes-detectable.

So weird. I don't know what I did differently. While stuck at "Starting FDR listener thread", I unplugged and replugged my iPad. The restore failed, iPad returned to restore mode. Then I ran it again, and even though it gave me a "Unable to connect to FDR client", it still went with the restore. Although, I've tried this so many times on my Debian install. This time, I did it on Windows with this: https://github.com/Devjam81/libimobile2019

[vaslabs]

basically had the same issue and added

info("Wait for your device to restart and then press enter");
getchar();

Just to control the flow below https://github.com/libimobiledevice/idevicerestore/blob/master/src/idevicerestore.c#L1371

I waited for a few seconds and then pressed enter

and worked with the combination of --erase --latest

Same error here, trying to restore an iPhone 3G model A1241, everything goes well until the iPhone goes trough the recovery mode, AFAIK the device has never been jailbroken before but it doesn't boot. Tried with the 2 currently signed firmwares, but the same error appears.

basically had the same issue and added

info("Wait for your device to restart and then press enter");
getchar();

I did this too, adding it to the line 1335 and 1336 of the latest release .bz2. But i doesn't worked. I also tried using the latest commit at this date (7b89019fbb81ce64e1c1d259c5746544c8e8eeea), it doesn't work too because of the SHSH thing that i don't know what is

Trying to fetch new SHSH blob
Getting SepNonce in dfu mode... 
ERROR: Unable to find required ApNonce in parameters
ERROR: Unable to add img3 tags to TSS request
ERROR: Unable to get SHSH blobs for this device

Tried using manually downloaded IPSW, with the --latest argument and with --latest --erase together arguments too. It also fails.

Plus i also have to connect the iPhone to iTunes (from a windows machine) first and then connect it to my Linux computer for some reason; Because when i boot into DFU mode normally, the iPhone is recognized as other DFU type (i think) and idevicerestore don't recognize it, so i need to connect the iPhone to iTunes first, and then to the Linux machine so idevicerestore can recognize it.

Entering DFU mode normally dmesg says:

[19600.632478] usb 1-10: new high-speed USB device number 42 using xhci_hcd

[19600.759458] usb 1-10: SerialNumber: [REDACTED] I should censor this?

Connecting the iPhone to iTunes and then to the Linux machine:

[19782.579522] usb 1-10: new high-speed USB device number 43 using xhci_hcd
[19782.707252] usb 1-10: New USB device found, idVendor=05ac, idProduct=1227, bcdDevice= 0.00

And with that is now able to be used with idevicerestore

Please fix this lol. If the devs need more information, just contact me
