1. flashed recovery 6.6.2 in fastboot mode OK (New boot screen appears) 2. pushed rectools.tar.gz into /sdcard/ OK (i was able to pull the file back, so i'm sure that the file is there) 3. "adb shell sync"ed OK (just dropped me down to a new line in terminal, nothing else happened. i wonder why this command is necessary, by the way) 4. reboot in recovery mode (both "shell reboot recovery"ed in terminal and pressed ok on the phone) OK 5. back in the mini recovery mode again! 6. tried to pull rectools.tar gz from /sdcard/ again. NOT OK (the file is not there) Tried almost hundred times. Restarting the phone erases the files in /sdcard/ and i can't use rectools to install new gaosp update.zip Any suggestions?
