Firmware Bundles Cannot Be Modified

If you are receiving an error when attempting to import your firmware bundles along the lines of "cannot be modified," please be sure that you have extracted all of the downloads from above to your Desktop(firmware bundle, firmware file and Pwnage Tool application). If you extract the files elsewhere on your computer you may receive a permissions error such as the one listed above. If you extract all the files to your Desktop you should not run into this error. After dragging the 4.2.8 bundle into the corresponding folder from above simply open PwnageTool and select "expert mode" and browse for the 4.2.8 firmware file you downloaded and follow the on-screen steps to create your modified firmware.

    Followed all steps but it gives me a 1600 error when I try and load the firmware.

      You have to be in pwned-DFU mode to restore a custom firmware

        How do you know if you’re in pwned DMf mode? I put it in dmf mode by following te steps on pwnage tools. I just get the apple boot logo an it’s stuck.

        • http://iphoneblogr.com JaeM1llz

          It’s DFU mode and you will know you are in it because the screen on your device will be black and iTunes will detect a device in recovery mode

    It won’t let me put the new firmware I downloaded into the firmwarebundles file because it says it cannot be modified, any ideas on how to do it?

    • http://iphoneblogr.com JaeM1llz

      You’re supposed to put the firmware bundles in the Pwnage Tool app folder just like it shows in the video.

        I have a similar problem: after inserting the bundle under Pwnage tool (which showed up under Devices menu), i am unable to select the bundle once i am asked for it going through the jailbreaking process — it is just greyed out. I am also unable to see Show Content until i hold cntl key and right click. I would greatly appreciate any suggestions you might have!

        one additional point i noticed — when i downloaded pwnage tool it did not come in zip format. i noticed that some intstructions refer to having to unzip the pwnage file.

    When I try to drag iPhone3,3_4.2.8_8E401.bundle file into the “FirmwareBundles” it say it can not be moved because can not be modified. What should I do?

    • http://iphoneblogr.com JaeM1llz

      Make sure that you extract the firmware bundles to your desktop and update the permissions.

      • Dallas Wood

        Now PwnageTool says wrong firmware bundle selected. I’m sorry to be an idiot but do you know what I’m doing wrong?

        • http://iphoneblogr.com JaeM1llz

          You’re using Pwnage Tool 4.2 correct? This tutorial will not work with the newest version of Pwnage Tool. That could be the issue, otherwise that error usually happens when you are using the wrong firmware for the device you are trying to restore.

    Thank you so much this worked so much. I tried Pwange Tool 4.3 and it did not load but this worked:)

      Thanks for the update! Glad it worked out for you!

    Recently I was using Ifile to browse my iPhone files and found a folder called My Mobile Watchdog. Any idea how that got installed?

    • http://iphoneblogr.com JaeM1llz

      My Mobile Watchdog is a parental control application that allows parents to monitor their child’s messaging and cellphone use. It doesn’t come preinstalled with anything so you must have installed it or someone else installed it.

    I get an error 21 from iTunes during the restore process. Any ideas?

    I get an error message saying that “iPhone could not be restored. this device isnt eligible for the requested build”..

    • http://iphoneblogr.com JaeM1llz

      That means that you are using the wrong firmware file for your device
