Custom Restore with checkm8-exploited 5C?

[KaehLikeTheLetterK]

I recently managed to get this exploit to work on this device, and I immediately jumped to trying to flash 9.3.5. Currently in pwned DFU mode, I tried the erase restore and here's what I got:

[kaeh@kaeh-arch ~]$ sudo idevicerestore -e -c ~/Downloads/iPhone5,3_9.3.5_13G36_Restore.ipsw
Found device in DFU mode
Identified device as n48ap, iPhone5,3
Extracting Restore.plist from IPSW
Product Version: 9.3.5
Product Build: 13G36 Major: 13
Device supports Image4: false
Custom firmware requested. Disabled TSS request.
Variant: Customer Erase Install (IPSW)
This restore will erase your device data.

I read on a few previous issues with similar topics that the "custom restore" option is only usable on the iPhone 4, but I figured that was due to the lack of a bootrom exploit for any newer devices. Is there anything that needs to be done on my end to resolve this and complete the restore, or is it simply a waiting game for this program to be updated to support checkm8 pwned dfu?
