They're in the biggest of the three DMGs (the one containing the root file system, it's 2.3GB in my IPSW), under /Library/Wallpaper/iPhone: Ringtones can be found in the same DMG, under /Library/Ringtones. Decrypting with ipswdecrypt.py. Go into the iPhone 4, 5.1 (9B176) folder or whatever folder was created depending on the firmware you chose. Open the biggest file ending with.decrypted.dmg in order to mount the disk image. In this example: 038-1768-165.decrypted.dmg. Re-encrypt the ramdisk: xpwntool restorerd.dec.dmg (or rd.udrw.dmg) pwnedrestorerd.dmg -t origrestorerd.dmg -iv. Replace the ramdisk inside of CFW produced by the Pwnage Tool with pwnedrestorerd.dmg You can either unzip and re-zip the CFW or replace it inside of /tmp/ipsw dir when PwnageTool is running. Jan 04, 2016 This file contains 3.DMG files; an Apple disk image witch is a disk image commonly used by the Mac OS X operating system. When opened, an Apple disk image is “mounted” as a volume within the Finder. One of the 3.DMG files contains the root file system.

IPSW, iPod Software, is a file format used in iTunes to install iOSfirmware. All Apple devices share the same IPSW file format for iOS firmware, allowing users to flash their devices through iTunes on macOS and Windows.

Structure[edit]
The .ipsw file itself is a compressedarchive file (similar to a Zip archive) containing three Apple Disk Image files with one containing the root file system of iOS and two ram disks for restore and update. Download postman mac.
The file also holds a 'Firmware' folder in which contains iBSS, iBEC, DFU, Battery Images (low, full, charging), and also the baseband firmware files in .bbfw format (Baseband firmware).
There are two more files named 'BuildManifest' and 'Restore Manifest', both in Apple Property List (.plist) format that checks the compatibility, holds the hashes in base64 format and instructs the device where to find the specific Firmware parts during the restore.
BuildManifest.plist is sent to Apple TSS server and checked in order to obtain SHSH blob at every restore. Without SHSH blobs, the firmware will refuse to restore, thus making downgrades impossible in official fashion, due to Apple's limitation.[3]
Security and rooting[edit]
The archive is not password-protected, but the DMG images inside it are encrypted with AES. While Apple does not release these keys, they can be extracted using different iBoot or bootloader exploits, such as limera1n (created by George Hotz, more commonly known as geohot). Since then, many tools were created for the decryption and modification of the root file system.
Government data access[edit]
After the 2015 San Bernardino attack, the FBI recovered the shooter's iPhone 5C, which belonged to the San Bernardino County Department of Public Health.[4] The FBI recovered iCloud backups from one and a half months before the shooting, and wanted to access encrypted files on the device. The U.S. government ordered Apple to produce an IPSW file that would allow investigators to brute force the passcode of the iPhone.[5] The order used the All Writs Act, originally created by the Judiciary Act of 1789, to demand the firmware, in the same way as other smartphone manufacturers have been ordered to comply.
Tim Cook responded on the company's webpage, outlining a need for encryption, and arguing that if they produce a backdoor for one device, it would inevitably be used to compromise the privacy of other iPhone users:[6]
The FBI wants us to make a new version of the iPhone operating system, circumventing several important security features, and install it on an iPhone recovered during the investigation. In the wrong hands, this software — which does not exist today — would have the potential to unlock any iPhone in someone’s physical possession..

The government would have us remove security features and add new capabilities to the operating system, allowing a passcode to be input electronically. This would make it easier to unlock an iPhone by “brute force,” trying thousands or millions of combinations with the speed of a modern computer.
The implications of the government’s demands are chilling. If the government can use the All Writs Act to make it easier to unlock your iPhone, it would have the power to reach into anyone’s device to capture their data. The government could extend this breach of privacy and demand that Apple build surveillance software to intercept your messages, access your health records or financial data, track your location, or even access your phone’s microphone or camera without your knowledge.
Opposing this order is not something we take lightly. We feel we must speak up in the face of what we see as an overreach by the U.S. https://imageever243.weebly.com/dd-5th-edition-dmg-4share.html. government.

- Unpack the original ramdisk:
xpwntool orig_restore_rd.dmg restore_rd.dec.dmg -iv . -k .
(use the keys from wiki) - (For those who have a 'read-only partition' error when modifying stuff on RD:
hdiutil convert -format UDRW restore_rd.dec.dmg -o rd.udrw.dmg
) - Mount the ramdisk:
hdiutil attach restore_rd.dec.dmg (or rd.udrw.dmg)
- Free up some space:
rm /Volumes/ramdisk/(some unneeded large-ish file)
- Patch asr:
mv /Volumes/ramdisk/usr/sbin/asr /tmp/; bspatch /tmp/asr /Volumes/ramdisk/usr/sbin/asr (bundle_path)/asr.patch
- Fix asr hashes :
ldid -s /Volumes/ramdisk/usr/sbin/asr
- Change the restore options: edit
/Volumes/ramdisk/usr/local/share/restore/options.plist
with Property List Editor, add 'UpdateBaseband' = false - see http://theiphonewiki.com/wiki/index.php?title=Preventing_Baseband_Update for details - Unmount the ramdisk:
hdiutil detach /Volumes/ramdisk
- Re-encrypt the ramdisk:
xpwntool restore_rd.dec.dmg (or rd.udrw.dmg) pwned_restore_rd.dmg -t orig_restore_rd.dmg -iv . -k .
- Replace the ramdisk inside of CFW produced by the Pwnage Tool with
pwned_restore_rd.dmg
You can either unzip and re-zip the CFW or replace it inside of /tmp/ipsw dir when PwnageTool is running.
