When I try to flash from fastboot, I get:
sending 'recovery' (4924 KB)...
OKAY [ 0.602s]
OKAY [ 6.409s]
finished. total time: 7.011s
But the recovery is still CWM, not stock.
The same thing happens with all other partitions: boot, recovery, system, userdata.
fastboot erase also has no effect.
What is wrong?
