    Greetings, fellow iOS people!:apple:
    I installed iOS 7 the night it was released and sure, there are a lot of great new features but I don't think it outweighs the fact that my iPhone have become slow... too slow in my opinion. Because of all this, I have decided to (try to) downgrade to iOS 6.1.3. There are several guides (like this one: http://www.redmondpie.com/how-to-downgrade-ios-7-to-ios-6-6.1.3-6.1.2-tutorial/) showing how to downgrade from 7.0.2 to 6.1.3. I'm not sure if it works for iOS 7.0.3 but I'm going to try it anyway.
    Okay, so I want to downgrade my iPhone, why start a thread about it when there are several guides I could follow? Well, I want to keep all the data on my iPhone (texts, apps, pictures etc.) and that could be tricky since iTunes won't let me restore a 6.1.3 iDevice from a 7.0.3 backup. I started this thread because I had an idea on how to do it and I want to hear what you thing about it/if it could work.

    This is how I thought I would do it:
    I have an Mac (iMac, middle 2011, 21,5", OS X Mavericks) with VMware Fusion (Windows 7 Home Premium 64-bit installed), iOS 6.1.3 SHSH-blobs and, of course, my iPhone 4.

    1. First of all, I need to find a third-party application that let me take a full back-up of my iPhone (since I want to keep everything on my iPhone and iTunes won’t let me restore with the 7.0.3 back-up on a different iOS-version). I have made some searches on Google, but before I decide for a alternative I would like to hear if you have any recommendations.

    2. Once my iPhone is backed-up I would download iFaith in Windows (since it's not compatible with Mac) and create a custom 6.1.3 IPSW-file with my SHSH-blob.

    3. I would then download and install iTunes 11.0 in Windows.

    4. Next I would restore my iPhone to 6.1.3 (in Windows)

    5. I would then use the third-party program to get all of my stuff onto my iPhone.

    6. Finally, I would connect my iPhone to iTunes on my Mac (iTunes 11.1.2)

    The only thing I am worrying about is how iTunes is going ot react in step 6. Do you think everything will work as normal?

    Do you think this could work?

    Thanks in advance!:) (And sorry for my bad english and structure)

    Looks like a winner, but use sn0wbreeze instead of ifaith

    Awesome! Thanks!

    Does anyone have third-party back-up software to recommend?

    Update!

    Hello again!

    For some reason I have not tried do downgrade after my last reply. Instead I updated to iOS 7.0.4 and time passed have passed...

    But after the release of the unthetered 6.1.3 jailbreak I felt that I really wanted to downgrade (again) I also found a guide (http://forums.macrumors.com/showthread.php?t=1613532) which I tried to follow yesterday. It all went well until step 16, when I was supposed to restore from iOS 7 to 6. I installed iTunes 11.0.4 in VMWare Fusion with Windows 7 64-bit (since I didn't want to lose my music, videos or backups on the Mac-part of my iMac) and then I tried to restore my iPhone to 6.1.3...for 4 hours... I tried both with custom ipsw files made in iFaith (iOS 6.1.3+SHSH blob for 6.1.3) and with just the ipsw file but nothing seemed to work (and yes, my iPhone was in PWND DFU-mode)

    Do anyone have a suggestion on what to do now?

    (To clarify: I followed the guide I linked above, but since I didn't want to uninstall iTunes (11.1.3) with the modified backup on my Mac, I used VMWare Fusion with Windows 7 to downgrade (which didn't work) The only difference between this post and the first one is that I'm now on iOS 7.0.4 and I'm planning on using the modified backup I've created with help from the guide mentioned above)

    Thanks in advance and Merry Christmas!:)

    what kind of error/problem are you getting? you weren't very specific in that aspect

    do you have complete 6.1.3 blobs? did you use the latest version of iFaith to check?

    Sorry, that's right. I have got iTunes error 1600 multiple times, error 1601 a couple of times and error 3194 once.
    I have googled on solutions for those errors but none of the ones I have tried have worked for me...

    I saved the blobs with TinyUmbrella when I was on 6.1.3 (<-- that's the one I tried to use during restore) And when I check on iFaith's (v. 1.5.9) SHSH cache server it says that blobs for 6.1.3 are available both from Cydia and from iFaith. Does that count as "complete"? (Sorry, I'm not sure what a complete blob is:))

    It's better to downgrade with ifaith. Make a custom ipsw with ifaith and it will automatically check if the blob is valid or not. Than use itunes 10.7 or any itunes that is below 11.0, make sure to save your itunes library befor install an old itunes version. Let me know if that helped you.;)

    Thank you so much for the tip, but unfortunately it didn't work:(
    I made a custom ipsw file in iFaith and it said that "The ap-ticket looks valid"
    Then I putted my iPhone in DFU-mode through iFaith
    And finally I tried to restore it in iTunes 10.7. Everything went well until the "Confirming iPhone-restore with Apple" stage. iTunes "worked on it" for a couple of seconds but then I got the "The iPhone-unit "iPhone" could not be restored. An unknown error occurred (1600)" error:(

    Could the problem be that I'm trying to do this in a virtual machine?

    I think this might be the problem, using a virtual machine. I think you should try without.

    if you type gs.apple.com in the browser address bar, where does it lead you? I also would assume you are in pwned DFU mode before doing the restore?

    the virtual machine might also be a factor

    If I type gs.apple.com in my browser (Safari) on my Mac, I get to this page: http://gyazo.com/295b48931c147ff3bf8e9ac4718ec711 and if I enter it on Windows (in VMWare Fusion) I get to this page: http://gyazo.com/92f0ace3b2b164e4fbdfb1e59262b64e Do you know why they are different? (and what is "gs.apple.com"?:))
    Yup! I have it both with Redsn0w and iFaith! But now when you mention it, I have experienced one problem sometimes: In the end of the "iFaith pwned DFU-mode" process, it runs iReb and then it says that my iPhone is in pwned DFU mode. But at the same time as this message pops up, my iPhone reboots (and that is definitely not DFU mode) Do you think that the virtual machine could be a factor here as well?

    As both you and rrares1996 have said, the virtual machine might be the problem. It would probably be better if I do this in Mavericks, but I'm afraid that I will loose my (quite big) media library and the modified back-up of my iPhone. Do you know if there is someway to avoid that I will loose this data while I'm installing a older version of iTunes?:)

    yup, there's your problem. your virtual machine is pointing at cydia's server. if you fix your hosts file on the virtual machine and have it point to what your mac is pointing, you will be able to downgrade no problem assuming everything else is correct

    you could do some searching online to find out how to fix your hosts file

    edit: on the other hand, i'm on my computer now and i use windows so i'll see what i can do to help

    1. browse to C:\Windows\System32\drivers\etc
    2. copy "hosts" to somewhere, such as the desktop
    3. open notepad
    4. in notepad, click file, and then open
    5. open the hosts file
    6. edit out the line that you see has gs.apple.com
    7. copy and paste it back to C:\Windows\System32\drivers\etc
    8. overwrite the current "hosts" file in there
    9. type in gs.apple.com to the browser webpage again
    10. if it leads you to the site you see on your mac, go for the restore again making sure you're in pwned DFU mode
    11. the restore should go through fine now unless there's something else wrong

    I have very similar problem to your's BoxerRobban472. Only diffrence I used 2 diffrent Pc's with windows8 64-bit. I used my6.0.1 blobs to create custom IPSW with redsn0w, and tried restroing with itunes (1st. 10.x, then 9.x itunes) every time it gives me error1600. I searched for error on Google, and found out it's something with usb ports? Changed all ports on booth pc's still error 1600. Some were saying about those host files mentioned above, I tried everything with hosts, still same?? Now I really don't know what to do with it.

    Oh and I used both DFU and Recovery modes to restore, booth gave sam results.

    you have to be in PWNED DFU mode to do custom restores. next, check to make sure you have complete blobs (use the latest version of ifaith and you can check by downloading the blobs from cydia's server)

    Is there any way to get in to PWNED DFU mode with a broken power button? Been trying to downgrade my iPhone 4 7.0.4 down to 6.1.3. I have all the valid blobs, however the only thing that is stopping me is getting iReb to run while it is trying to detect DFU mode. I've only been able to get into RECOVERY mode using Tiny Umbrella but not PWNED DFU mode, or DFU mode for that matter.

    well, there's the thing about redsn0w and a firmware package that will make you go into DFU mode. once in DFU mode, you can run iReb and put it into pwned DFU mode

    I've never tried this method though so not sure how great it will work

    Thank you so the for the guide! I do not longer get the 1600 error in iTunes!:)
    Instead I get the 1604 error.. But at least I am one step closer! And I think I know what the problem is:
    When I try to enter pwned DFU mode with Redsn0w (0.9.15b3, I have tried both in Windows and Mac) it says that "the exploit failed" and my iPhone turns on.
    Almost the same thing happens in iFaith; I do all the steps, my screen turns black, but when the "Running iReb" comes up in the end, my iPhone turns on... I seem to be able to enter DFU mode, but how do I make it pwned after that?

    ----------

    After some quick googling I found out that error 9 occurs when "This error occurs when the device unexpectedly loses its USB connection with iTunes." Maybe it's enough to change the USB-port?:)

    I am really tired of this now!:mad:

    I can get my iPhone into pwned DFU-mode now, the problem was that I could't have WMware running at the same time, but anyway, I have tried every "alternative" to using iTunes 11.0.4 (or lower) but nothing seems to work. I have now come to the conclusion that I will need to downgrade iTunes on my Mac to make this work. But as I have mentioned in previous posts I don't want to loose my media library, and I think I have a solution to that now:

    I'm planning on buying a hard drive so that I can use TimeMachine to take a backup on my Mac. And then I got an idea, do you think that it would be possible to:

    1. Take a full backup on my Mac
    2. Uninstall the current version of iTunes
    3. Download and install iTunes 11.0.4 and downgrade my iPhone
    4. When the downgrade is finished, I restore the whole Mac from the backup and everything will be "just as before".

    Does this sound like it could work?:)
