DoCoMo SC-03E / Samsung Galaxy S III alpha
Reset "Custom Binary Download", "Curren Binary", "System Status" for factory default and warranty
Since I did try some "declamed" official European ROM on SC-03E (no one still can be fully flashed by Odin), my counter on the "Dowload mode" screen was increased.
So I was hoping to use Triangle Away... but the available Sock Prerooted ROMs online actually don't make the SC-03E rooted [the combo of the tree buttons (even with USB Debugging enabled) just makes a device "fast restart" (without the usual menu), while performing the combo on switching the device on, nothing happens] and all the links from aki0306 are no more on line.
Make a backup!
I have tried many ways.
At the end, the ONLY working has been this:
Flash SC03E-JB-KBC-CWM-V188.8.131.52_r0-recovery-odin.tar.md5 from PC by Odin tool [PDA field]
Wipe cache partition from CWM "Bootloader Mode" on the SC-03E
Wipe data/factory reset from CWM "Bootloader Mode" on the SC-03E
Wipe dalvik cache from CWM "Bootloader Mode" on the SC-03E
Flash cm-10.1-20130329-KBC-sc03e.zip from micro SD, by CWM on the SC-03E
Install, launch and apply Triangle Away on the SC-03E
Let the phone reboots, BUT DON'T LET the OS be loaded! PUT IT SOON IN DOWNLOAD MODE (volume down + home + power) BEFORE OR AS SOON AS THE DOCOMO LOGO APPEARS
Flash Stock Official ROM by Odin tool from PC
[IMPORTANT] Cache Wipe from official "Bootloader Mode" on the SC-03E
[IMPORTANT] Factory Reset from official "Bootloader Mode" on the SC-03E
At the end you will get
Reset Custom Binary Download: No
Curren Binary: Samsung Official
System Status: Official
Kies recognize the device as usual.
