I recently soft bricked my Sprint Samsung Galaxy S4 while trying to unlock the device to make it work with other US carriers (not sure if that would work). I modified the build.prop file following http://forum.xda-developers.com/show....php?t=2530610 forum. I think I did not made the correct changes and after that phone keeps rebooting. Phone shows Samsung Galaxy S4 logo and wouldn't pass this. Prior to this I did not make any copy of the files so doing a restore from back up is not possible at this time. I don't care about the data being lost. I only care about getting the phone back up and working.
I canget to ODIN mode and recovery mode. I had previously flashed it with SPH-L720_MDC_Modem.tar.md5 and CF-Auto-Root-jfltespr-jfltespr-sphl720.tar.md5 using ODIN before the problem started.
I tried all possible way to get my phone working but still it keeps rebooting.
1. wipe data/factory reset
2. wipe cache partition
3. tried to update from ADB - this i can get to list my device using (adb devices) but cannot get to push or pull /system/build.prop file to edit it. I get "error:closed" when I type in "adb usb" or "adb shell". I was able to log in as SU prior to this problem. I have the latest SDK installed.
I know for sure that I had checked the "USB Debugging" checkbox prior to this issue.
4. I tried flashing it with L720VPUAMDC_L720SPTAMDC_L720VPUAMDC_HOME.tar.md5 but I get the error that Binary=1 in download mode. Not sure if Triangle away apk will be of any help here to reset the binary counter since I cannot get past the samsung logo at all.
In recovery mode, my system reads:
Android system recovery <3e>
In ODIN mode, my system reads:
Product Name: SPN-L720
Current Binary: Custom
System Status: Custom
KNOX Kernel: 0x0
KNOX Warranty Void: 0x1
WRITE PROTECTION: Enable
eMMC BURST MODE enabled
Can someone please help me to fix this issue? I can provide more information if needed.
Thanks so much.
