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.

The rollback algorithm for the iPad is the same as for the iPhone, only the firmware and pwnediBSS need to be changed. Download here:https://yadi.sk/d/JkNQzCX6hgE6i

Maybe this is not the topic, but the speed of iOS 6 is so magical that there is no strength to tear myself away.

I will say that you need to switch to iOS 6.1.3 because:
Internet works 3-4 times faster in safari
YouTube video is no longer late
Programs open and run faster every 1.5
The battery holds the charge longer well in my opinion is 15% more
Sensor definition increased 2-2.5 times
YouTube’s loudness was 2 times louder than others

About the beauty do not take, then to each his own)

Some applications will not run, but the phone, maps, skype Vibers, etc. will be.

With regard to iOS 6, this cannot be called a rollback; this UPDATE to the six is ​​discussed here. Because it is the best that Apple had in the firmware.

Oleg4483,
Oleg - write in a personal serial number. There is a suspicion that the iPhones of September release and later of 2014 were already on the 8th axis, but with them mine problem with rollback. From what year and month of release your iphone, and which axis stood right away?

[Tolbas]

And your two 8 gigabytes from which year of release and which axis was it?

Well please help !! I do everything according to the instructions for windows !!!! Everything is all and more than once before, everything was done and not a novice in this matter, but it does not work either to roll back your 4S to 6.1.3, iphone was bought a month ago with 8 ios !!! what could be the problem? the terminal on the computer just crashes at the moment of sending (1227867) .... and quickly crashes with some kind of error, but I don’t have time to read it, it crashes and that's it !!!!!! what to do???
Here I have it in December 2014, do not roll back, huh?

[Tolbas]

blisssss07,
Give the exact date of release of the iPhone ... I come to the conclusion that the 8GB iPhones are older than October 2014 (after the 8th axis came out), can not be rolled back ...

Tolbasdaaaa December 2014, with 8, 8gb (((((

[Tolbas]

blisssss07,
Well, it means to be patient and wait for the solution of the problem ... In the near future, the utility should come out, not this instruction, on the downgrade from under Windows. Can she solve this problem ...

[Maedhros]

After I wrote in ./kloader pwnediBSS, an error failed to get appears. Kernel_baseel base ...
How to solve?

[Tolbas]

Well, guys .. I guess I read here a week, read it, asked again, and now I decided. IPhone 8 GB, released in June 2014, came with firmware 7.1.2. After reading the forum, I sewed on 8.4, jail and then everything on video instructions -https://www.youtube.com/watch?v=Fsuz-OYBmeg- and as a result 6.1.3 from under Windows 7 32 bits, without any questions. Contacts pulled from Aiklaud, pictures and music on your computer.

Did anybody try to roll back the iPad 2,3 cdma ?!
Or am I the only one with such a device onsavagemessiahzine.com!?

[kenny_1989]

Rollback, a good thing. The device came to life on 6.1.3, everything was smooth and fast, but Apple buried it in terms of application support. I used one day, half of the applications are not installed, and if installed, they do not work correctly. Creaking my heart rolled back to 8.4 ... I think that a late rollback came out ... It would be very relevant at the time of release 7

Kenny_1989 @ 07/10/2015, 22:20

I believe that the late rollback came out ... It would be very relevant at the time of release 7

Similarly. Let's wait for iOS 9, Apple seems to have promised a separate version for 32x processors. Starting with iOS 7, this is already calculated at 64x. And so 6.1.3 quickly, smoothly, but not relevant today, unless the one who uses the smartphone exclusively, as a dialer uses.

Moro,
And I agree and disagree, rolled one of 4s to 6k, everything that needs to be established (except for movie search, I love to buy movie tickets through it), but for good, it is used as a dialer and as a multi-function dialer 4ske has no equal to 6k. On the 8th bottom, on the 9th is even worse. 7.1.2 is the same on the second one, it works not much worse than 6, and sometimes even better, only it keeps the battery worse.
