future restore fails #52

Closed shMatrix closed 11 months ago

shMatrix commented 11 months ago

Once future restore starts restoring and after red yellow green display blinking I'm getting next error:

Done: restoring failed!

if nothing works just try to run (with sudo or without) this command: /home/user/downr1n/binaries/Linux/futurerestore -t blobs/iPad5,3-14.3.shsh2 --use-pwndfu --skip-blob --rdsk work/rdsk.im4p --rkrn work/krnl.im4p --latest-sep --no-baseband ipsw/iPad_64bit_TouchID_14.3_18C66_Restore.ipsw
if futurerestore restore sucess, you can boot using  --boot

Tried this command. With sudo getting:

Futurerestore is up to date!
[INFO] 64-bit device detected
futurerestore init done
reading signing ticket blobs/iPad5,3-14.3.shsh2 is done
User specified to use latest signed SEP
Segmentation fault

Without sudo same as initially.

It helped thanks. Future restore succeeded and I got message to use --boot for booting device. But unfortunately it stuck here after executing the command:

Tried fixboot, localboot, fsboot, same error. The device has black screen and doesn't react on any buttons.
