Make yourself some custom ramdisk that bypasses iCloud in some way. Use 'ipwndfu' and the 'checkm8' exploit to execute said ramdisk, bypassing iCloud. Stop raising issues that are in fact not issues (like this one). Well agreed, Windows Support ones, this, et cetera.

The new Redsn0w, like PwageTool and Sn0wbreeze, lets you create custom firmware to preserve iPhone baseband. You can create custom IPSW firmware with RedSn0w with preserved baseband so you may unlock with UltraSn0w or Gevey SIM.
For those unfamiliar, a custom firmware, unlike stock firmware, preserves your iPhone baseband. With a preserved baseband you can unlock your iPhone either using UltraSn0w or Gevey SIM depending on your current baseband version. Before RedSn0w, Sn0wbreeze (Windows only) and PwnageTool (Mac only) were the two options available to create a custom firmware. RedSn0w just makes the process more simple.

To make it easy to type the command line later, you may rename the.shsh2 file to “my.shsh2”, iOS 11.0.3.ipsw file to “restoreto.ipsw” and iOS 11.2.6.ipsw file into “signed.ipsw”. Step 2: Open your.shsh2 as text using Notepad and find your generator key string, something like 0xab12c34d5ef6ab7d. Step 4 Now drag the.ipsw file over to the.exe file. Step 5 Windows will now display a security prompt asking you to run this file. Press the Run option. Step 6 The.exe file will now automatically launch a Command Prompt window. Be patient and wait for it to unpack the IPSW file. Step 7 After a while, it will display “Press Enter to exit”. Create a folder in your desktop containing the following files: futurerestore.exe, your SHSH2 blobs, and IPSW file. Open a command prompt (cmd.exe) and drag the file futurerestore.exe inside the prompt. Press spacebar and type –t, then press spacebar again. Drag your SHS2 blobs file and then press spacebar.

Once the RedSn0w is done with building your desired custom firmware, a success window will appear.

You can find a new custom IPSW file in the same folder where your original (stock) IPSW file was located.

Note: RedSn0w adds “NO_BB” to the name of the custom firmware so you may distinguish it from stock/original iOS firmware.

Warning: If you depend on UltraSn0w or Gevey SIM unlock, you want to preserve your iPhone baseband. BE VERY CAREFUL to NOT ACCIDENTLY USE THE STOCK IPSW! select only the one beginning with NO_BB_*. Stock firmware will update your baseband and you will loose your unlock.
