My problem is that I messed up some binaries in the ROM on my Samsung Galaxy Y (GT-S5360L). Specifically, most of the binaries in
/system/bin are gone, thanks to Busybox Installer. This means I can still use my phone for basic things (calling, texting, music), but advanced things like connecting to wifi, turning on "find my mobile," etc, are now broken. Naturally, I got Samsung Kies, put my phone into download mode, and tried to reflash the firmware. The only problem is, after Kies downloads the firmware, gives the appropriate warnings and disclaimers, and says "preparing firmware," it gives me a random error in Chinese. (I can't read Chinese, sadly.) I rebooted my phone, its the same deal, nothing has been changed. (Luckily, my phone has not been hard bricked.)
I have already tried flashing with Kies again, same problem. I tried connecting the USBcable to another port, and using a different USB cable, nothing worked.
Why doesn't a firmware upgrade with Kies work like it should? All help is greatly appreciated.
