[Q] Need help with a soft brick (ODIN doesn't work)
I have been researching this problem for a while now and I have read all sorts of threads from forums in every corner of the Internet, but I'm still completely stuck. Any help is greatly appreciated.
What I have is a SCH-i535 Verizon Samsung Galaxy S III (the model # behind the battery actually says SCH-i535V). It belonged to a friend of mine who announced he would be going "Office Space" on it after it stopped functioning. Seeing an opportunity, I asked if I could have it. This friend used his phone solely for regular Internet browsing, texting and email. He never flashed anything custom and it has never been rooted. As of this writing, download mode reports:
Custom Binary Download: No
Current Binary: Samsung Official
System status: Official
Qualcomm Secureboot: Enable
For the record, I don't know any details about the exact version of Android the phone ran before it failed (but I'm operating under the assumption that it ran 4.1.2).
When I first received the phone, it wouldn't get past the "Samsung Galaxy S III" boot screen. It also will not boot into recovery. It will, however, boot into download mode. Therefore, I booted it into download mode, hooked it up to Odin 3.09, downloaded the latest stock firmware from sammobile, and attempted to flash via Odin. Every time I try to do this via Odin 3.09 or 3.07, Odin hangs on the "Initializing" step and does nothing. Samsung drivers are installed, and Odin definitely recognizes the device.
I began researching and came across the Sudden Death Syndrome thread here,
which is caused by eMMC failure. My symptoms sounded like the "Half SDS" symptoms in that thread (You cannot boot into android or recovery. It fails at the boot screen, but the screen does turn on none-the-less. The only; thing you can do is top boot into Download mode.). However, I believe SDS affects only the international versions of the SGS3, but please correct me if I'm wrong. Thus, I wrote SDS off.
Next, I attempted to use Kies to restore the phone. Using Kies, I used the firmware upgrade/recovery tool. It went through its thing, asked for my model number and IMEI, then downloaded the proper firmware. When it came time to install, however, it told me that it could not communicate with my device. Since then, when I power the phone on, instead of the Samsung boot screen, it now displays "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." Download mode still works, however.
After reading about Odin issues, I tries using older versions of Odin. When I tried to flash the stock firmware using Odin 3.04, rather than hang on "initializing" like the later versions, 3.04 specifically says that there is no PIT partition. Ah, another clue! So I went in search of what the hell this means. By the way, I also tried different USB cables, different computers, different USB ports, popping the battery in and out, standing on one leg and clucking like a chicken, sacrificing a virgin, you name it. After trying Kies, I uninstalled it, and I double checked task manager. Kies is not running the background during my Odin attempts.
I finally found a 16GB PIT file for the SCH-i535 and downloaded it. I loaded it in Odin along with the "re-partition" option checked, and that's also a no go. The write just fails without any particular explanation. Just says "Complete(Write) operation failed. All threads completed (succeed 0 / failed 1). I even tried Odin 1.85, but same result.
I looked into JTAG, but that appears to be necessary if the phone is completely unresponsive and all it does is get you back into download mode. Well, I already have download mode, I just can't do anything with it. This leads me to believe my device is soft bricked, and not hard bricked.
I also followed a couple of tutorials that incorporate flashing bootchains using Odin (like the one here)
, but Odin wouldn't flash those either.
: ODIN won't write anything to my phone in download mode, and Kies can't do anything either.
I'm at the end of my rope. Short of an actual eMMC failure, I can't see any reason why this phone would be permanently bricked or why ODIN refuses to cooperate. Can anyone suggest anything?
