Iphone4s downgrade from 8.x.x to 6.1.3 becomes possible

first of all thanks to Bbs.feng 's feimummy for giving me a successful tutorial. Ok here not much wordy, with my test method hope can help the need to downgrade friends.

1. The necessary tools are Odysseusota,win32openssl-1_0_2c,winscp5.7.3 so you don't have to worry, kit I packed, the following.

:Http://pan.baidu.com/s/1hq8enNA

This toolkit is complete, PC-side downgrade tool, OPENSLL, and downgrade package, as well as iOS 6 jailbreak tool, and old version 32-bit and 64-bit itunes (downgrade iphone4s can be performed under the latest itunes, But the jailbreak requires an old version).

2. Connect your computer and phone to the same LAN with WiFi.

3.iPhone 4S jailbreak, use Cydia source to install the OpenSSH plugin (my own 4S software version is 8.1.1), while in the back up your phone files, the brush is to clear the data.

     here to start the downgrade step:

The first step is to install the necessary software on the computer (here is my environment, WIN8.1 64-bit)

Open the downloaded file and you'll find win32openssl-1_0_. 2c.exe (pro-Test 64-bit computer can be installed this 32-bit, do not have to look for 32-bit) and winscp5.7.3.5438setup.1432114150.exe (software installation Here I will not write a simple way next will be)

After completing the software installation, to check whether your computer can connect to your phone, on the phone to find the mobile phone access to wifi IP address, set-"wi-fi--" point you connected to the WiFi can see the IP address, run in the computer after the cmd and then use ping 192.168. x.x can pass on OK.

Connect the phone with WinSCP, username is root, password is alpine by default.

The second step allows for risk warning

Third Step copy File

When you log in, drag the Kloader,pwnedibss two files in the package into the root directory of the right window.

Fourth step to the third step into the iphone file execution script needs to write the command line, simple copy can be.

You need to copy and paste the execution, and then copy and paste the execution, one at a time.

chmod +x Kloader

./kloader PWNEDIBSS

Then your phone will go black and enter DFU mode, and itunes will recognize it as a waiting-for-recovery iphone, regardless of itunes, and if it does, turn it off. (If the downgrade fails or regrets, to exit the DFU mode, just long press the home Plus power button to boot.) ）

Fifth Step data Cable connect iphone and PC, execute related commands in DFU mode

After you open the Idevicerestore for Windows folder, hold down SHIFT and right-click to execute cmd under the current path.

Sixth step in the pop-up cmd window paste the following command

Idevicerestore.exe-efistmedaddy.ipsw

Phone response not so fast, will be in the black screen DFU mode to write data, about two minutes after the hand lit:

Wait patiently, go to the cmd window to prompt the done word to disconnect the USB connection, and finally enjoy the classic iOS 6!

The above steps to test and success in person, there is no success is normal, big deal start again, close out of the DFU mode here I do not elaborate, online related methods flying around. I hope I can help a friend in need.
