i wonder why everytime i try to wipe something from mirecovery i always got stuck at 90-98%.. when its stuck i force shut down the device, reboot the device and the wipe is actually completed.. and when i try to flash the ROM from mirecovery using update.zip (which is the ROM package that i downloaded from en.miui.com and rename it to update.zip) also gives me error that says file corrupted(im 100% sure that the file is not corrupted, because it works fine when i flash it using updater) and i force shut down the device again. and do a normal reboot, and the ROM is actually flashed successfully. i can get in to phone. can someone explain to me what causes this? how long does it take for wiping process to complete? i have waited for 15mins.. i believe 15mins is long enough to wipe or install something.. im sorry, im not a good story teller.. please try to understand my story..
