To all of i9100 users having flashed the latest 4.0.4 firmware (Official / Leaked) with stock kernel, PLEASE BE AWARE that using cwm to erase data/factory reset OR to restore a nandroid backup MAY BRICK YOUR PHONE !!!! Trust me, I just got mine bricked and by searching a litlle bit I discovered I'm not the only one -> see here and here ... and the number is growing ...
Actually confirmed firmwares having the emmc bug :
XXLQ5/6/7/B - ZCLPL - XWLPM/O/T/U - MUGLD3(?)
Here's how to BRICK your phone :
-Flash the 4.0.4 firmware with/without its pit file
-Use any 4.0.4 based kernel - stock or modified (ex cf-root)
-Go to cwm and do a wipe data & wipe cache and/or perform a nandroid restore of any previous firmware
=> The process begins normally but it may/will switch off at any time without waking up ever again !!!!!
Symptoms of 4.0.4 HARDBRICK :
-Phone dead
-No power up
-No boot
-No download mode (odin mode)
-No charging (usb/ac)
-Not detectable by pc / jtag
-Usb jig & jtag useless
-With battery(charged) inserted, phone(off) gets hot near the camera lens
-JUST A PIECE OF PLASTIC !!!!
-You feel really stupid about trying all this new stuff
And now here's how to avoid 4.0.4 hardbrick :
-DO NOT flash any stock 4.0.4 firmware
-If on 4.0.4 stock firmware, keep away from stock kernel (ex: use siyah kernel or latest speedmod)
-Use "eMMC Brickbug Check" app to verify whether you have an insane ship or not
-Backup your apps (titanium backup) and backup all (cwm) and copy all data from internal sdcard
-DO NOT wipe any partition or data
-Flash any official 4.0.3 stock firmware in download mode via odin (do not use mobile odin)
-Do not get tempted again by any unsafe leaked or official firmware !!!
Downgrade from 4.0.4 :
-Reboot the phone in download mode (Home+Vol.Down+Power)
-Use Odin to flash a safe kernel (ex. siyah) then reboot to cwm (Home+Vol.Up+Power)
-Optionally do a nandroid backup then perform a data wipe/factory reset
-Use advanced menu in cwm to reboot in download mode to flash your preferred "safe" firmware
While waiting for someone to find a way to revive such bricked phones, I hope you guys take care of your precious S2, you only know its value when it's gone
