Why does flashing my Tab3, 7.0, 8GB, WiFi (sm-t210) fail with Odin?
As Odin in Windows doesn't seem to work for my device, I tried another application such as Heimdall-Frontend.
This application differs from Odin in that it uses the extracted files from a stock ROM where as Odin uses the stock ROM to upload to an connected device.
Anyways, I found that from Heimdall all files are successfully downloaded to the Samsung Tab3 device.
Yet there was a slight difference between the download of 'system.img' file and all the other 9 files out of the stock ROM.
After the download from Heimdall completed, it was released and right after that the Tab3 device goes into reboot.
While after the download of all other 9 files, it took a few seconds before the Tab3 goes into reboot.
So my guess here is that right after being released, the Tab3 goes immediately into reboot and deletes that way the successful downloaded 'system.img' file.
That would also explain as to why there's no change after the successful flashing with Heimdall.
