I use HTC One S.
Under "settings ----> storage" information about the Internal storage and the Phone storage are shown and there is the possibility to encrypt the Internal storage as well as the Phone storage.
Does encryption of the Internal storage and/or the Phone storage has any negative impact on the function of ClockworkMod Recovery especially then if one tries to boot into ClockworkMod Recovery from power off state because the storage is then encrypted?
This is what I believe.
If I turn on the phone and use ClockworkMod Recovery v184.108.40.206 to backup the current rom the phone reboots into ClockworkMod Recovery v220.127.116.11 which starts the backup. The backup is stored in /mnt/sdcard/clockworkmod/backup.
/mnt/sdcard is the Phone storage. If the Phone storage is encrypted, it is only accessible after the screen lock PIN or password is entered while the phone is turned on.
If I use ClockworkMod Recovery v18.104.22.168 to backup the current rom the phone reboots into ClockworkMod Recovery v22.214.171.124 which starts the backup. In this case the encrypted Phone storage is not accessible by ClockworkMod Recovery v126.96.36.199 and therefore ClockworkMod Recovery v188.8.131.52 will not be able to safe the backup to the Phone storage.
That's why I believe that ClockworkMod Recovery v184.108.40.206 does not function if the Phone storage is encrypted. But I don't know whether I am right or wrong. I can not test this with simple means because it is not possible to undo encryption. To return to an unencrypted phone, it is necessary to perform a factory reset. Factory reset will permanently delete all data and customized settings. Testing this is very cumbersome.
Who knows something about this topic?
