a9-checkm8-nonce-setter-script VS checkm8-nonce-setter

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.

This should do the job. I’ve never used so I cannot provide any more info on how it works

https://github.com/MatthewPierson/checkm8-nonce-setter is the one that I used. Repo hasn’t been updated for a while

Use this tool to set nonce, then use futurerestore. But I think you need a mac for the tool. Not sure if there is a linux version.

I can give you my experience with my 7+. In the past few months, I entered a phase of experimenting with checkm8-nonce-setter and futurerestore gui. Wanted to try ios 15.1, 15.3, then got back to 14.8, with a couple of bootloops along the way. While I bootlooped my device, because of a bad fr. I set my nonce with the above tool, on mac, and was able to fr to 15.1, back to 14.8, and a few weeks ago, from 14.8 to 14.8. Mac, or a hackintosh is the best bet in my opinion.

I'm trying to set Nonce to my iPad7,3 (10.5' Pro WiFi only) so that i can downgrade using Futurerestore. I'm unable to get it to work. Can someone get me the iBEC and iBSS file so that i can use it with Checkm8 Nonce Setter [https://github.com/MatthewPierson/checkm8-nonce-setter].

When I try to run ipwndfu --patch-sigchecks for checkm8-nonce-setter with hack-different's fork of ipwndfu I get this error (tried different macbooks: 2015, 2019, M1, with different Linux and Mac, the error is the same everywhere):

TLDR: I am currently at A10 iOS 15.3.1 with 14.8 blobs saved. ipwndfu + checkm8-nonce-setter does not work, it either says:

Yes. Use https://github.com/MatthewPierson/checkm8-nonce-setter tonset nonce then beta version of futurerestore to downgrade.

Yes it possible with futurerestore. I saw somewhere that you can use the option called: ap nonce collision or use this shell script: https://github.com/MatthewPierson/checkm8-nonce-setter
