Redsn0w “Unable to recognize specified IPSW” Error in 0.9.5 with iOS 4

While trying to jailbreak (before unlocking) your iPhone 3G / iPhone 3Gs on iOS 4.0 using Redsn0w 0.9.5 you may have received an error saying:

Unable to recognize specified IPSW

So how to fix this unable to recognize specified ipsw error in redsn0w while jailbreaking your iPhone?

Well to be honest this is not a technical error with redsn0w unable to recognize specified IPSW (4.0 iOS firmware)while jailbreaking your iPhone. It just takes abit of common sense to avoid and / or fix this error because redsn0w is simply not able to recognize the ipsw file that you specified, means either redsn0w have some problem or the ipsw file that you are using.

How to solve Redsn0w “Unable to recognize specified IPSW” Error in 0.9.5 with iOS 4

If this error that “Unable to recognize specified IPSW” keeps bugging you by popping up whenever you try to select the downloaded iOS 4.0 firmware file by browsing for it in Redsn0w 0.9.5 while trying to Jailbreak (before unlock probably) your Apple iPhone 3G / iPhone 3Gs, you can fix it simply by making sure of these 2 things:

  1. Make sure that the right version and the latest build of Redsn0w is being used. To jailbreak iOS 4.0 on iPhone 3G / iPhone 3Gs you need Redsn0w 0.9.5 beta 5 build 3 ( download it from here for: Windows (old link not working: http://sites.google.com/a/iphone-dev.com/files/home/redsn0w_win_0.9.5b5-3.zip )  | Mac (old link not working: http://sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.5b5-3.zip ) ) Maybe because your redsn0w version is not compatible with the ipsw or iPhone that you are trying to unlock, that’s why it’s giving error that it isn’t able to recognize the specified ipsw file.
  2. Make sure that you are using the right build of iOS 4.0 firmware specific for your Apple iPhone (3G or 3Gs). There may be confusion as  the GoldMaster release and final release use the same build number and file name for both builds is same. But you have to use the official iOS 4.0 for this purpose. You can see the list of the official download link for iOS 4.0 here.
  3. Make sure that the file that you downloaded is having extension .ipsw (and not .zip) if it is .zip, then rename it to .ipsw
  4. Change the folder for your redsn0w and ipsw file. If they are on desktop right now, make a new folder on desktop and move them inside that folder and launch again.
  5. Make sure that iTunes is updated to latest version.

Hopefully this will solve your “Unable to recognize specified IPSW” error in redsn0w 0.9.5 and your jailbreak procedure goes smooth.

    and am still getting the same message. I tried redsn0w 0.9.5b5-5 and also 0.9.3

Anyway I hooked it up to my itunes all excited to upload my songs n what not, updated, set out to JB & unlock and as you all know turns out im a f**kin idiot, so whats a blobless guy without his SHitSHit suppossed to do? Is my phone jailbreakable?

Someone help please, god let the torture end!
    thx!
    tb

    1. lolx. liked your comment though

      anyway, as you said you’re on old bootrom, then it can be done without shsh too.

      let me know if it’s still locked

  6. Hey guys i found a solution to the “unable to recognize specidfied firmware”.

    If the firmware you download from apple is iPhone1,2_4.0.1_8A306_Restore.ipsw.

    Then download the firmware 2_4.0_8A293_Restore.ipsw.

    Redsn0w will detect the 2_4.0_8A293_Restore.ipsw as your iphone 3g firmware and it will work.

    Hope this works for u

  7. unable to recognize ipsw

    im getting this error can anyone help?

    im using redsn0w 0.9.5b-5 and iPhone3,1_4.0.1_8A306_Restore.ipsw

    but where is the Option key?

        3GS on 4.0.1, 5.13.04 base-band, doesn’t see the ipsw file, does not recognize it at all.

  11. Hi, i have been trying to complete this alllll night to no avail grrrrr.

    I have redsn0w_win_0.9.5b5-5 and have tried

    iPhone1,2_4.0_8A274b_Restore.ipsw,
    iPhone_1,2_3.0_7A341_Restore.ipsw

    but neither work, i have installed the Os4 legit through Itunes already onto my handset, its a 3g 8g but the newer ones – does this mean that i am not able to jailbreak it?

  12. Anyone know why mine’s not working? I have a 3GS and I’m trying to use iPhone2,1_4.0_8A293_Restore.ipsw with redsn0w_win_0.9.5b5-5 and I’m getting the same error.

    1. Same problem with me the exact same software and hardware you’re using..
      Sam: fresh copy didn’t work either..

      I updated to 4.0.2 (8A400) by Itunes, i assume that you all have the same update?

  13. I have the 4.0.2 (8A400) and I’m getting the “unable to recognize specified IPSW. This is my first unlock attempt so it’s been touch-and-go for me. I am guessing that there is no crack out yet for the 400 series? Thanks.

  14. I have a 3GS with 4.0.2 and I am using Windows Vista. I am using Redsn0w 0.9.5b5-5.

    I have tried following all of the steps including using the 4.0 ipsw file but I am still getting the same error message. Have you any suggestions?

      1. I have already changed the file extension to .ipsw as it wasn’t showing up on Redsn0w.

        Any other suggestions would be much appreciated. Thanks in advance.

          1. Nabeel, thank you for your help so far.

            I have tried the additional suggestions (changed folder in which the .ipsw is located & ensured itunes is up to date) and still get the same error message.

  15. I have a ipod touch (Non MC) 2nd Gen

    IPSW file name :- iPod2,1_4.0_8A293_Restore.ipsw

    Redsn0w file name :- redsn0w_win_0.9.5b5-5.zip

    still has the same error “unable to recognize the specified IPSW”

  33. I guess posts on this board are not displayed immediately? I posted something around 4:00pm yesterday, and it only appears as though it appeared on the site at 1:35 am

    I only saw it appear once I posted another comment, which is not up yet either.

    Are posts moderated or something? If not, something is awry.
