[BREKING NEWS] Galaxy Note ICE CREAM SANDWICH leaked! GT-i9220
Happy You Galaxy Note users. Seems like some user from China GFAN forums leaked early build of ICE CREAM SANDWICH for Your devices! Of course do a FULL backup (strongly recommend doing also EFS backup) and flash! This is a version for GT-i9220 (Galaxy Note in China) yet users report that flashing PDA file only makes it work also on N7000. There are also info that there will be a ‘following leak’ with a proper N7000 firmware but no details, no data so… if you can not wait and must test …
and here is CFROOT for this firmwre version: >> DOWNLOAD <<
To flash on N7000 put it into DOWNLOAD MODE,
(UNTESTED)insert “I9220_CODE_I9220ZCLP1_CL131270_REV02_user_mid_nos hip.tar” into PDA field and go.
(TESTED-WORKING)Or do the same with MOBILE ODIN with permanent root enabled (open file “above” and flash)
To flash on GT-i9220 simply put extracted files into respective folders at Odin and flash.
Take a peak at this screenshot for proper odin-file-placing for GT-i9220.
And here are few screenshots from the ICS itself running on N7000
