FAQ

The flash device should not just be on the same wifi subnet from the PC, but if the PC is connected via a router, then it should be accessible from the PC to the flash device (checked by ping).

If you encounter this errorLibrary not loaded: /usr/local/lib/libirecovery.2.dylib Referenced from: / Users / "username" / Desktop / odysseusOTA / macos /./ idevicerestore Reason: image not found then you need to open the terminal again (from scratch) and enter the following commands:

sudo chown -R `whoami` / usr / local (can ask for a user password)

Next, install Homebrew by running this command:

curl -L github.com/mxcl/homebrew/tarball/master | tar xz --strip 1 -C / usr / local

Now most important, enter this command:

brew install libpng (if the terminal gives an error, then type brew install libpng --universal)

After the done actions, you can read the process of downgrade again.

Aytyuns was the last one, downloaded the aytuls, Jail put it, 2 files were transferred to the Jale category in the aytuls, I installed a program for Windows, but in the terminal, with "chmod ......" I wrote that no files were found. What is the problem ? Purely stuck on the terminal with these last commands. And so everything went according to plan.

[myrzin.pasha]

If the phone is purchased on 8K, then it can not be rolled back. imho

Everything is possible. I rolled back bought on 8-ke.
The topic, of course, is time to clean. It would be nice to put in a band for new devices.

[mamedovelvin]

How so? (All exactly in the category of Jale these 2 files are thrown, and I try to another? She, here I think in another matter ..

I did everything from the video in the cap in English. So there, these two files are thrown into two places: to the root (I can fuck up with the wording because the jail did the first time and did not work with iOS in this way) and to the System folder (like), but you can see everything it shows there.

[Tolbas]

begemo3,
I also noticed this identity ... But I was embarrassed to ask again ... There he really throws 2 places ... Who has any thoughts on this?

And yes. And where is the video on ang. under Windows in the cap? There only on Linux ...

I also launched a video now, I wanted to find where the files were thrown, but it’s not that ...: blush:
Now I find ... Here!https://youtu.be/Fsuz-OYBmeg
I took all the files by the links under the video. In my opinion, very detailed and understandable. There is a video, and at the bottom there are all steps.

I did with iPhone 4S 16Gb iOS 8.4
Did on Windows 8.1 x64

P.S. I threw these two files (kloader and pwnediBSS) (as in the instructions) intoPrison break systemand inPrison break system \ System

VETAL_x86,
first you need to put jail, go ahead

[VETAL_x86]

Jail on icloud can not put = (

[sh1zeR]

Boys shorter do this:

Download programs.

Install iTunes
Install OpenSLL
Install iTools
Make jailbreak
Cydia:
update is displayed - click the full update
from cydia.angelxwind.net - install MobileTereminal and OpenSHH
from apt.taig.com - install TaiG AFC2

Libimobiledevice throw on the C drive
via iTools, we throw two kloader and pwnediBSS files into the very root of the iPhone, and we also throw them into the System folder

Further in the terminal on the iPhone enter:

cd ..
cd ..
su
alpine (password is not displayed)
chmod + x kloader
./kloader pwnediBSS

after that, your phone goes into Recovery, disconnect the USB from the phone for a couple of seconds and connect it back.
Next, run the command line (open the start and write in the searchcmd): enter cd c: \ libimobiledevice and press Enter
after that there will be a new path, enter further idevicerestore -e custom.ipsw
Next, on your device, an apple appears. IOS 6 means the phone has started to flash

everything worked for me on Windows 7 x32

If the file folder is on the C drive (Windows), i.e. like this: C: \ libimobiledevice
Then we run the command line on the computer (I ran as administrator, I don’t know if there is a difference)
Just in case, we write:
1) cd \ press Enter
2) then with: press Enter
3) then cd c: \ libimobiledevice and press Enter
