I'm a custom ROM on Android 4.2.2 and used the Settings > Privacy > Encrypt phone feature. What exactly did this do, did the encrypt the internal SD card, the external SD card, the entire filesystem (i.e. root of filesystem), or some combination?
If it didn't encrypt my external SD card, how can I do so? But if it did, how can I access the contents of my external SD card (after providing my PIN/password) from a laptop when I put the SD card in it? Would I just mount it like I do any other encrypted USB drive with LUKS?
If not, then isn't it risky because if my phone gets broken and I must start from a new ROM, then I've lost my most recent data (backups could be a few days old). Or lets's say someone flashes a new ROM, the new ROM wouldn't be able to read the card, or would it be able to if you use the same PIN/password?

Encrypted internal /storage/sdcard0 cannot be read after installing new ROM while using same password, just checked.

I encrypted all my files on my external SD card.
I then wiped and installed a new ROM.
Now i cannot read the files on my SD card.
Is this because it was all encrypted under the old ROM?
As far as I know the phone creates a unique key for the encryption, so you couldn't read the sd card in another phone. By changing the Rom you've effectively changed phone, so the sd card is locked.
Either format the card, if you don't need the data, or restore an earlier nandroid (if that will recreate the key) to access the card again if you need the data.
Dear All,
I encrypted my SD card using the encrypt SD Card feature in Android Lollipop. Later, I upgraded my phone to CM13 Marshmallow and I removed the SD Card from my phone during the entire process. Once the new ROM has been installed I encrypted my phone internal memory using the same password as the one I used to encrypt my SD Card.
Once I reinserted my SD Card, the phone couldn't read the encrypted files stored in there. Everytime I try to open a file (image, music, video...) it says "the file couldn't be opened it could be corrupted or damaged".
Can anyone tell me how to restore data on an encrypted SD card ? Of course, I know the exact password that was used to encrypt the data on the SD Card.

I thing you didn't get the point actually. Files are not corrupt, they're encrypted and I'm looking for a way to decrypt data using the encryption password.
i have same problem, please some one help.. thank you
Hi,
I own an Acer Liquid Z630 that I successfully rooted following this guide. I unlocked the bootloader, flashed TWRP and installed the SU zip, everything's working perfectly.
But during the process, my phone somehow decided to "switch" internal storage and external SD card, making SD card the default storage. SD card is now labelled as sdcard0 and internal memory as sdcard1, while it should be the opposite, and apps data are now written on the SD card instead of the internal memory.
When I unmount the SD card, internal storage becomes default storage again and is correctly labelled as sdcard0, but as soon as I mount it again, the same problem happens.
I want default storage to always be internal storage, even if the SD card is mounted, like it was before. I don't want my phone to write any file on my SD card, I only want files I put myself to be on my SD card.
I tried factory reset, but it remained the same. I did a little searching and saw a lot of threads with people asking how to make SD card the default storage (in my case, that's the exact opposite), but apparently, on Lollipop there's no way to change default storage. But it did change when I rooted my phone...
I also thought about updating to Marshmallow, as I heard storage is managed differently, but there's no official upgrade by Acer, and I could'nt find any unofficial port for Z630.
This has been bothering me for quite a while now and I don't konw what to do anymore, so any help would be greatly appreciated!
Thanks in advance!
Anyone ?

I have an UNROOTED ACER LIQUID Z630 and it does the same.
Its not a matter of it being rooted or not; every time you mount an SD card, memory option nº1 for the mobile is SD card.
Hello there.
I have android phone with 9.0 firmware. When I bought the SD card and installed it, my phone asked me how I would use it.
I selected this variant:
Internal storage:
You can store apps and data for this device only. If you move the SD card to another device, the SD card will be erased ("formatted"). After the SD card is erased, you can use it with the other device.

The problem is that:
I got bootloop after some manipulations with firmware. So I had to make Factory Reset. Before that I've removed SD card from phone. And now I can't use this SD, because it's ext4 and something like "protected". My PC can't open disk even with ext4 reading tools. When I install this SD to the phone, it asks to formate SD and select the option of use.
How can I get back my data from this SD card?
Phone the card came out of is a Doogee S68 Pro. I configured the SD card to be internal memory and for the camera app to save pics taken to the SD card. I assumed when the SD card was full the camera would save back to the internal memory but instead it gave an error saying storage full and wouldn't take more photos. There was no option within the camera app to switch the save location to the internal memory so I removed the SD card. This forced the camera to now save to internal memory. BUT. Now when I put the SD card back in it doesn't read and says I need to format the card to use it. Same result if I put the card in different android phones or pug it into a PC. I don't want to format the card because I want the pictures on it.
How can I get the image files off this SD card? I've tried a few file recovery programs without any success. I don't have a linux machine, just a PC, and I have no experience with rooting phones or the like.
Probably card is in raw mode now.
What you mean by saying that you have configured card as an internal storage?

The External SD-card got encrypted as soon as you decided to use it as internal memory. It's no longer readable by any card-reader. IMHO forensic tools are needed to retain the data stored there.

When I pulgged it in the first time it gave two options, use as internal memory or as mass storage device. I choose the internal memory option.

I feared this was the case. I don't understand why the original phone cannot decrypt the card though as it would with a Samsung device. I have sent a support request tot he phone manufacturer so hopefully that bears fruit.

Ok thank you for confirmation. As above card encrypted and furthermore you might have lost all the data of the phone as well as sms , apps, updates basically everything since you choose that option has been storage on ad card, and your internal storage was not used or useless in a different world, access has been denied to it.
Which tools have you tried to recover data?
