a9-checkm8-nonce-setter-script VS FutureRestore-GUI

Hi all, I have been trying to set the nonce on my phone using the Checkm8 nonce setter, after it tells me to set my device in DFU mode, i get the error - "./main.sh: line 138: ./ipwnder_macosx: Permission denied". The script continues from there but doesn't actually set the nonce as the it is unchanged when it reads it again at the end. I've been at this for hours, any help is appreciated.

There is a script for A9 nonce setter on linux. I know because I use it yesterday lol: https://github.com/rA9stuff/a9-checkm8-nonce-setter-script

There is this nonce setter but it is mac only, uses checkm8, and requires a computer. Why can't you just jb with checkra1n to set the nonce? And why do you need to be on 14.6? Checkra1n will work up to 14.8.1 on A9 devices.

This one supports iPhone 6S but unfortunately it's also mac only. Are you running iOS 15?

Step 1. Download the nonce setter script from rA9stuff/a9-checkm8-nonce-setter-script: A nonce setter for devices compatible with checkm8 (github.com) . Download using the "Code" then "Download .zip" from github.

People here keep saying Futurestore is unavailable for Windows, only Linux or Mac, but I am finding installers for Windows like FutureRestore-GUI-Windows-1.98.3.msi here. Am I missing something?

Download VMware Workstation and Catalina.iso and install MacOS. Here you can find Catalina iso https://ibb.co/NmzzSM5 Then download Futurerestore GUI and install it. Off course you set the right nonse. Click download futurestore. Click Blobs Click Target Ipsw I used this as options, https://ibb.co/7ndkjqz And Click Start. Be patient and you get back your iPhone up or downgrade without losing anything. 👍🏼

- Download Futurerestore-GUI from: https://github.com/CoocooFroggy/FutureRestore-GUI/releases

install FutureRestore-GUI in your Mac

I had previously saved blobs for iOS 15.4.1, and after restoring rootfs (without enabling OTA updates), I used futurerestore-gui v1.98.2 to update the device. The computer I used was a 2021 Macbook Pro 14" running MacOS Ventura Beta 7.

Where I’m from it’s 2am and I’m already half asleep so my advice to you is, download both 15.7 and 15.4.1 .ipsws to get them ready, check futurerestore-gui github, and, if you understand completely what’s documented there, backup everything important (not a full itunes backup tho as it probably won’t work on an older version than the one it was created) and try to downgrade using 15.7 sep. If you have questions on any parts of the procedure, I’ll be more than happy to help you tomorrow morning.

Try with futurerestore GUI https://github.com/CoocooFroggy/FutureRestore-GUI/releases
