Posted on :

This post here will help you to unbrick hard bricked Sprint Samsung Galaxy S3 and will restore the phone in a state so that Odin can be used to restore the ROM. This post is for hard brick phone only.  (See the difference).

We are not responsible for any data loss or other problems that occur by using this tutorial. Flashing ROM deletes internal memory. Use at your own risk.

Requirements :-

  • 1
    Bricked Galaxy Note 3 (SM-900A)
  • 2
    microSD card  and card reader (all data will be erased from this sdcard)
  • 3
    Linux / OS X ( can use vmware or live running OS)
  • 4

    dmesg | tail

    You will get output that will show that SDCard is mounted via /sdX

  • 4
    sudo dd if=/<path_to_unbrick.img> of=/dev/sdX

    X is taken from the step above. Ignore the partitions since they will be removed automatically.

  • 5
    sudo fdisk -l /dev/sdX

    It should show approximately 29 partitions . Again X is from above.

    Remove the battery and SIM from your device and insert the SDCard and insert the battery again.

    can it work on windows 8?

    • RohanKandwal

      it might but that will be painstaking task. Why don’t you use a live version of Linux? You could use Ubuntu, Fedora, Mint, etc. Make a bootable pendrive and live boot from it.

      From there you could run the above commands and have your phone back in no time.

        Important: One of my friend is also having the same mobile phone, with running on same android OS. Is it useful for me to do something with that mobile to bring my mobile back??

        I have
        1. Hard bricked Samsung skyrocket SGH-I727 (AT&T)
        2. Samsung OEM Data cable
        3. Sandisk ultra 16 GB class 10 SD Card.
        4. Windows 8.1 OS
        5. Win 32 image write Application.

        Kindly advice me please………
        You are my only hope now…

        • RohanKandwal

          If you are unable to create a debrick image then you will only have JTAG option left for you. It might cost you some bucks but will (99%) brick your device back.

          • Jagadeesh

            My dear bro,

            Thankyou verymuch for your guidance..

            One more doubt , when i flash that zip to make the debrick image, after that do i need to reflash the OS? or i can simply reboot the system??

            Kindly let me know bro…

          • RohanKandwal

            The debrick image generally contains all the low level information needed for the device to boot up. If your /system isn’t affected then you can use you device simply but you must have the debrick.img all the time on your sdCard. If you don’t want to rely on the sdCard all the time then you will have to flash the stock firmware using Odin.

            But in your case, you flashed wrong firmware which messed up the bootloader partition and might (99%) have damaged the /system partition (which contain Android OS). Thus, specially in your case, via debrick you will be able to boot into the Download Mode and then from there you will have to reflash your device using Odin. After that, keep the debrick.img for safekeeping and your device will no longer rely on sdCard.

          • Jagadeesh

            So i will bring my friends mobile, and i will flash that zip file using philz cwm running on same kitkat 4.4.4 which was installed on my mobile while brick, so i will flash that zip file in his mobile and can i need to reflash the os in his mobile after flashing that zip file? or can i simply reboot his mobile after flashing that dumb file in his mobile?

            is that makes any problem to his mobile for booting?
            or can i proceed the steps right away?

            Your guidance is much valuable for me…

          • Jagadeesh

            Dear Rohan,
            With your guidance i have made the debrick image for my SHG -I727 Samsung galaxy skyrocket mobile, its showing around 128 MB, i have done successfully up to that, after that
            I was writing that image to my SD card by using win 32 disc imager,
            it shows writing successful, but after that my memory card shows 0 bytes used space and 0 bytes free space,
            after that i read that SD card using win32 disc imager, it shows around 15.5gb file, so please let me know ., Is tha happened because of Insuffcient memory in the SD card??
            or else please let me know How to reduce the size of the debrick image file..??
            Kindly let me know this, as am in the final stage , so please help me…ASAP..

      • Jagadeesh

        Somebody is given in xda forums, one dump zip file to make the debrick.img, they mentioned its comon for all samsung phones, and we need to flash it with cwm or TWRP, am not clear with that process,
        Also am scared to use my friends mobile to do so.. so, please advice me the detail and right procedure for me bro……

        Thankyou in advance….

        • RohanKandwal

          Sorry for not being able to help you, new job is taking lot of my time. Anyhow, saw what you were saying “T999_Partial_Sys_Dump_for_debrick.zip”. Don’t worry that it will brick your friend’s device, it will just copy data, write nothing so either it will create a debrick image for you or it will give you an error.

          I tried the file on my Galaxy Ace but got error, it might work for you. No harm in trying. On CWM or TWRP go to “Install .zip from SD card” and then find the .zip file. If everything went smoothly, you will find a debrick image on your sd card.

      • Jagadeesh

        Rohan any reply from you is helpful…..

  • John

    Just to clarify what Hard bricked means…were you able to get ANYthing on your display before doing this? I tried this…and it is well written, but I have no display at all. I can’t get into CWM or download mode either…Dead…I even bought the Jig thing….nothing. would you have any other suggestions? Thanks!

    • RohanKandwal

      Hard brick means the device is like a paper weight, no life at all. This tutorial will help your device to get into “Download Mode”, from there you can use Odin to flash your device.

      I am sure that you tried it, but it might take some tries to get your device into the Download Mode. Double check everything.

    Ok, i flashed a custom rom and as an idiot i checked 2 kernels to flash at the same time, it flashed i knew that once i clicked restart it would not turn back on, tried the back button but it only let me use restart……. long story short, i wrote this debrick image to a sd card, checked the md5 of the sd card all was correct, popped out the battery of the gs3 l710 and popped in the sd card, put in the battery, pressed and held vol+, home, pwr…. nothing…… tried again with a usb in the computer to see if it needed more power…. lo and behold, nothing……… i have windows seeing it as a unknown driver, i think a qhsusb, i flashed using linux mint on my hp mini…..
    i know linux fairly well, i know it wrote to the sd card good, can you help me?
