Redsn0w 0.9.9b1 การเปลี่ยนแปลงครั้งใหญ่ของ Redsn0w

การใช้งานที่เราจะได้ใช้กันบ่อยๆ แน่นอนเลยคือ ปุ่ม Jailbreak ในหน้าแรก สำหรับการเจลเบรคเครื่อง และในส่วนของ Extras ที่ได้ใช้ก็น่าจะมี

• Just boot, Pwned DFU, Recovery fix, SHS blobs ในส่วนของ fetch และ query เพื่อจะดูค่า ecid ที่ได้เก็บเอาไว้จะได้นำมาพิจารณาว่าจะดาวน์เกรดได้หรือไม่นั้นเอง

• uses DFU mode to try to automatically determine which device and FW you have
• fetches pieces of public IPSWs from Apple (once).  Non-public IPSWs must be provided manually (once).  It then caches those pieces for future use.
• “Just boot” is a tethered boot.  Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
• “Pwned DFU” puts your device in a pwned DFU state for some of the iTunes stuff detailed below
• “Recovery fix” gets past 1015 types of errors (when baseband portion of restore fails).  Should work on iOS5 beta too
• “Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
• “SHSH blobs” has a bunch of options…
• “Fetch” – fetch current PARTIAL blobs on device.  Should complete in under 10 or 15 seconds.  Puts the set of PARTIAL of blobs on your computer as a plist.  Checks if Cydia already has a full set for this device and build.  If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
• “Verify”  – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server.  You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory)
• “Submit”  – both verifies and submits one or more blob files to Cydia.  This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
• “Query” – queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
• “Stitch” – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW

1. Stitching is NOT yet supported on iPhones!  Need to work out the baseband part of the restore process.
2. FULL blobs stitched to a STOCK IPSW gives you a completely self-contained signed IPSW that iTunes will accept without any tricks (no need to go into pwned DFU mode, no need to start TinyUmbrella TSS server, no need to redirect to Cydia server for blobs)
3. PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU mode before running iTunes.  No need to start TU or use Cydia though.
4. Stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires a pwned DFU start before iTunes restores.  No need to start TU or use Cydia though.
5. Will eventually support fetching the blobs directly from Cydia instead of a file on your computer
