    Actually could you post a software to get and decrypt it? I think that would be a lot more useful. Thanks

    The moment they do that is the moment I'll put my Galaxy on ebay and stop preaching about great Samsung phones.

    Thanks sephail for the firmware. Is it possible to flash just the csc onto a phone that is already running H8?

    So far i've extracted the cache.img and put it in it's own tar file. I have then gone and loaded Odin and then selected the OPS file. Next I have then selected the CSC file pointing it at my cache.tar. I then set my phone up into download mode and connect it to my computer and see that Odin recognizes it. I click start and it says "Check Image Files". Am I missing a step?

    Wouldn't the rest of the files flash on a older version of firmware?

    i used to have this problem, no matter what firmware i tried to install.

    what worked for me was doing the install from another computer. don't know what caused the problem on mine.

    maybe related to your problem. maybe not.

    As an alternative method you could try using the modified recovery image to apply the CSC. You need to extract the zip from the image though. That can be done with unyaffs: unyaffs - Project Hosting on Google Code

    The resulting .zip is a valid OTA and can be applied as update.zip from the recovery menu.

    I haven't tried it, but i don't see any other reason why it wouldn't work than the signature within the zip file. If the recovery image doesn't know the signature, it might not allow the update to proceed.

    Other than that, the zip file is the same as the update.zip file, including a valid update script within the package.

    Right..

    So you need to sign the package with SignApk before applying the update. Other than that, it's a working OTA.

    So, to recap: extract cache.img from the tar, unyaffs the img to get the zip and pass the zip through SignApk, apply as an OTA through the modified recovery, profit!

    Remember to wipe your system after applying, the CSC update screws up your system pretty bad (it's the same as seen when upgrading from G-series to H-series)

    And now to restore the backup and return to a CSC free life ;)

    Hey Sephail,

    Not been near a computer in several days and then I return to find you've cracked it! Good work!

    Wondering if you can give me a PM to let me know what the missing ingredient was?

    Well done!

    Chris

    Could you upload it somewhere else like say megaupload? I can't get files from rapidshare. Thx
