    Fix for Cricket Galaxy S3 Hard Bricks on Android 4.3

    The premise is this: Your device has a built-in mechanism whereby it will search for a bootable structure, and boot to it. If it determines that the internal storage is corrupt or unusable in any way, it will look to the sdcard. The sdcard should equal the storage space and structure of the internal memory as closely as possible, and should be a Class 10 speed rating. All you have to do is provide it with that structure. Click the link below, and download them.


    https://drive.google.com/folderview?...00&usp=sharing




    Download either sd-debrick.img.tar.7z or sdcard.img.7z (the larger one may work where the smaller one may fail).

    extract them until you get to the .img file, and go to Linux terminal prompt.

    type (don't use {}, they're just there to illustrate a variable): dd if={filename you extracted} of={mount point of sdcard}
    example: dd if=sd-debrick.img of=sdb
    NOTE: You're not writing to a partition on the sdcard, but the sdcard itself. Be sure not to specify a partition number (sdb1), but instead the entire device (sdb).

    Put the sdcard into your phone, and hold down the power button + volume down to enter download mode, and immediately flash a ROM using ODIN. Try to flash the same ROM you had before the brick.



    If you're on another software version than 4.3

    1.) download the firmware that you need from sammobile.com
    2.) write the sdcard contents from one of the files I've provided to provide the partition structure
    3.) extract the contents of the .tar file to a folder and navigate there through the terminal
    3.) use the dd if="" of="" to write each partition to its appropriate place. For a list of where things should go, click the above link and look at the partition table file.

    The partition table can be a little confusing when comparing it against the files contained in the firmware .tar file. You may need to try several combinations before getting a working debrick sdcard, but I assure you it's possible.

    When you've got everything from the firmware in the appropriate partitions, make sure that all the partitions have a file system matching the partition table. If anything shows up as RAW, format it to what the partition table says it should be. Then plug the sdcard in, and power up.

    Flash a STOCK ROM immediately with ODIN, and do your best to make sure that it's the same firmware that was on your phone when it bricked.

    If you've been using an AOSP ROM, disregard the android version number of the AOSP ROM. The only thing that matters in this respect is the LAST OFFICIAL STOCK ROM you were running before the brick. I'm sorry if some of this is redundant.

    If I've failed to mention anything here, check

    for more details.

    Enjoy having an unbrickable device!

    Thanks for this very useful post... unfortunately my R530C phone was on 4.4 Stock firmware and the 4.3 sdcard unbrick will not work.
    Do you happen to have the 4.4.2 files so I can create an sdcard that will hopefully work on my phone?

    Best Regards!

    Thank you,
    But the phone is hard bricked... No lcd power, download mode... Recovery etc.
    I was looking for the 4.4.2 image in order to try the sdcard unbrick method.

    I messed up my s3 recently and could not get into recovery or download mode. But I had a usb jig off ebay which let me boot into download mode and flash the tar.
