Help Can't Restore Samsung Galaxy S3 To Factory Firmware

[Gradyn Wursten]

I installed CyanogenMod on my Samsung Galaxy S3 (SGH i747), and now I need to re-install factory firmware to network unlock my phone. Heimdall seems to be able to successfully image the firmware package onto the device, but after imaging, it won't boot. I can still get to recovery mode and download mode, but nothing else. This is the command I'm using to image:

heimdall flash --SYSTEM I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.tar.md5

This is the output:

Heimdall v1.4.1

I tried factory resetting before and after imaging the ROM via ClockworkMod, but it didn't help.

How do I fix this?

NOTE: I am using Linux.

Do you have access to a windows machine?

Have you tried re-downloading the firmware file on the outside chance the one you used was in some way 'broken'?

Also, don't forget while you're in Recovery Mode to wipe the system cache partition after you've reflashed the firmware.


... and this isn't a deal-breaker but just note for reference that CWM and Philz are no longer actively supported.

If I remember, to install CM13 on my SII, a virtual repartitioning had to be done. In order to return to stock this needed to be reversed prior to flashing. I'm not sure if this is the case with the S3 now or not.
These older phones were not designed to hold system partitions that require the space of more modern Android versions.

Depending on which Android version you were on priorr to installing a custom recovery and Rom,you can not downgrade.
I found this a few days ago and it is supposed to work with Odin

Other than this would be to flash TWRP and use its terminal to determine the bootloader you are on and go from there.
