RedSnow 9.15b1 hỗ trợ downgrade IOS6 về IOS5(Chip A5) có lưu SHSH
New Features:
● Downgrade hoặc Upgrade trên 5.x thoải mái miễn là có SHSH Blobs
● Tự động có Cydia trên iOS 6 nhưng chỉ TETHERED
● Tự động Justboot khi phát hiện máy Chip A4 connect với máy thông qua cổng USB
UNTETHERED cho máy 3GS OLD BOOTROOM
● Hỗ trợ h@cktivate trên iOS 6 cho iPhone 3GS/4
● directly restore pre-A5 devices to earlier firmware - no more complicated 15-step how-to's with stitching, iTunes errors, and "hosts file" concerns
● fetch new signed blobs for any IPSW (present or future - no redsn0w update required) using Extras->SHSH Blobs->New
● Chặn không cho update Baseband trên các máy lock iP3Gs/4 thông qua: Extras->Even More->Restore
● Hỗ trợ Deactive iPhone, hữu ích cho những bạn nào muốn test máy mình đã được unlock chưa thông qua iTunes
● Tethered Jailbreak Apple TV 2 (but the only thing available for it is the SSH2 custom bundle available here - no Cydia yet. Must use "Select IPSW" for tethered boot of ATV2 for now).
● Redsn0w sẽ tự động Save SHSH mỗi khi bạn fetch SHSH Blobs từ Cydia hoặc Apple, nếu bạn muốn Restore về FW nào đó mà stitch SHSH, chọn Local
iOS 5 to iOS 5 Restores for A5+ Devices
1. Hỗ trợ các máy chip A5(x) restore iOS 5.x miễn là có SHSH của FW đó
● APtickets eliminated "higher-version only" comparison of firmware restores (just like BBtickets did for the baseband)
● Có thể Downgrade hoặc Upgrade thông qua các FW sau: 5.1.1-to-5.0.1, 5.0.1-to-5.1.1, 5.1.1-to-5.1.1, 5.0.1-to-5.0.1
● Nếu bạn không có file SHSH thì hãy dùng chức năng Fetch của Redsn0w
2. Bạn không thể sử dụng chức năng Downgrade về IOS 5.x nếu như FW của bạn đang dùng được update qua OTA
● the tickets saved by Cydia, redsn0w, and TinyUmbrella do not cover OTA update ramdisk images
● even if they did, it's the "wrong kind" of ramdisk (you'd need to start at that earlier pre-OTA FW)
● devices fresh from factory or refurb may fall in the "does not qualify" category (your results will vary)
● it's okay if you previously got to 5.x via an OTA update, as long as your current 5.x was installed via a normal iTunes restore. All that matters is how you got to your current 5.x most recently
● redsn0w detects an OTA/normal-restore APticket mismatch very early, so if you don't know your status there should be no harm in trying. Any device in recovery mode after such a mismatch can boot normally again just by going back to "Even More" screen from the "Restore" screen (or use "Recovery Fix" if you quit redsn0w before doing that).
3. Không giống như chip A4, Redsn0w không tự động lược bỏ Baseband ở Chip A5(x) vì thế khi Restore lại iOS 5.x sẽ bị nâng Baseband nhé
● and so, redsn0w automatically flashes the currently signed baseband when it does A5+ restores, even if those basebands didn't come with the original firmware
● stay away from this if you have an unofficial unlock that isn't supported by the newest baseband
● the least-tested baseband update code in redsn0w is for iPad2,3 and iPad3,2. Please give any feedback on those iOS5 restores in the comments section below.
4. Những người dùng iPad 2 (cả 3 phiên bản) có thể Restore về iOS 4.x nếu như có SHSH
● if you have both 4.x and 5.x iPad2 blobs, you can always get to 5.x via the 4.x blobs, even if you're currently on 6.x
● you cannot get to 5.x from 6.x without the 4.x blobs (but you may still qualify for the iOS5-to-iOS5 restore described above)
● if somehow you have 4.x blobs but no 5.x blobs, you can still go down to 4.x from 6.x
● this only applies to iPad2 owners (they're the only A5+ devices that ever had a public 4.x FW)
● redsn0w still supports (but doesn't require) jailbreaking A5+ devices at 5.0.1 and 5.1.1. Just head back to the first page after re-restoring to 5.x. It's always much faster to jailbreak those FW versions with a freshly-restored device, before letting iTunes restore from a saved userland backup.
5. ULTRASNOW chưa hỗ trợ trên iOS 6
● by now you probably should be taking advantage of the extremely cheap IMEI-based unlocks of iPhones sold by established online retailers like http:://cutyoursim.com
● still, IMEI-based unlocks don't work in all cases. We'll announce when ultrasn0w is ported up to 6.x
● redsn0w will still hactivate your 3GS or iPhone4 if you run it before the device is activated. Due to the current tethered 6.x JB status, redsn0w now hactivates 6.x without requiring subsequent tethered boots. If you accidentally hactivate with redsn0w, use the "Deactivate" checkbox available from the Jailbreak screen, not the normal one in "Even more"

Cập Nhật RedSnow 0.9.15b2 Sửa Lổi JailBreak 3GS
Update #1 (Oct 15): Version 0.9.15b2 fixes a few issues for 3GS owners: old-bootrom awesomeness is no longer forgotten directly after a restore, and iPad baseband upgrade/downgrade support is fixed (same production date cutoffs apply!). If your 3GS is currently tethered at 6.0 even though you have an old bootrom, just re-run redsn0w’s Jailbreak step (no need to restore). Don’t forget you can add some pizzaz with your own boot logo or a nerdy verbose boot.
Here are the download links. Enjoy!
