[Q] SD card encrypted - How to recover?!? - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

My Z3+ was acting strange after OTA to android 6.0, so decided to repair with PC companion.
I did backup but didn't backed up SD card, at that moment I thought it wouldn't be necessary because repair doesn't delete anything.
And it's true but I completely forgot that my phone was encrypted, also the SD card.
So now I can't use my SD card files. Any one know if I can get encryption key from my backup? I know the unlock password but I suspect it uses another one that was on my old system
Thanks!

Encryption through Android and flashing roms? External SD Card

welp I may be screwed, but thought I would ask the pros.
I always back up my sdcard personal files, but the media files (music I don't). I have a 128GB card and I am trying to save myself some rebuild time.
I encrypted my external 128gb sd card in android (I have my data backed up thank goodness), but I have full wiped the phone, to install a new rom (full wipe and factory reset).
I have rest the screen password to the same encrypted password, yet when I reboot the phone (installed new rom from separate external sd card since TWRP wont write from an encrypted sd card), the phone is fine, but the card is still being shown as "checking sdcard for errors"
is there any way to restore access to the encrypted card since I full wiped? I know that I can just reformat the card back to fat32, but I really don't want to sit and transfer 100gb of flac files again.

[Q] How to decrypt sd card

Hi ,
here is my problem:
I wanted to install a new rom , so first i have to unlock my bootlaader .
I do this but before that , i do not back up all my data (yes, i was stupid ...). of course i have a back up of my msg and contact and ...
in my sd card .
After booting from unlock boot loader i see that my phone has been reset and all of my data looses.
The problem is that my sd card encrypted with a password so i can't view its content nor connect it via mass storage to pc
to copy my data.
So is there anyway to restore sd card because i have my sd password ?
I just want to decrypt the sd card or something that i can restore my data in sd card.
Best Regard

The phone must detect that the sd card is encrypted and ask me to enter password to decrypt it.
But it didn't .
What happened when i encrypt my sd card so every time i power up the phone it detect it ?
Why it cannot detect it now?
of course when i say sd card i mean phone storage.
Best Regard
Your data was erased by the system.and I think you will never find the data again.

xperia z1 recover deleted photos

i'm trying to help out someone who has fallen victim to a fake unbranded micro sd card from ebay.
they bought what they thought was a 64gb card, then tried to move all their photos and videos to it. as the sd card was reporting a capacity of 64gb, the phone tried to move all of it, and deleted it all from the internal storage.
my first port of call was photorec, because it's what i've used before, but that's only any use for recovering from the external sd card, the internal storage will only connect as an mtp device, which photorec doesn't see.
i then rebooted into windows and started trying different android photo recovery software. the closest i've come to success is with dr fone, but that either gets stuck at 90%, or tells me the phone will have to be rooted to recover anything.
the phone is already on the latest firmware version, which i believe means it will have to be downgraded before rooting. is it possible to root it in a way which won't overwrite the internal storage, so i can still recover the deleted photos after rooting? alternatively, is it possible to use ADB to force it to mount the internal storage as a mass storage device rather than MTP?

Unsupported SanDisk SD card problem after factory reset

Hi guys,
I have hard-reset my Moto G 2nd Gen after some confusion. I have taken the SD card out of the phone before resetting it. Now after hard-reset, when I insert my SD card into the phone, it says "Unsupported SanDisk SD card" and ask me to format it to use either as a portable storage or as internal storage.
This card has some important data of mine, e.g. Photos, whatsapp backup and few other backups. How can I solve this problem? I want to use this card as is in phone. Can I take backup of it's data if it's required to format this card?
I know I have asked too many questions, I hope you can understand my situation here. :crying:
If your SD card was formatted as internal storage it's almost impossible to get the information back since when you format an SD card as internal storage it gets encrypted and the key is stored in the device, so when you hard reseted your phone the key was lost, that's why it can't be identified.

as you said "almost impossible", is there any way to get the info back? Moreover, if I had left the card in the phone, would it have changed the encryption of sd card?
It most probably would've been the same if you had left the card in the phone. By the way you may want to take a look a this "Decrypting Android M adopted storage"

Thank you for sharing this page. This is a very good article, but it talks about having the key from device, which I certainly don't have. So, it seems I can't use this method to recover my data.
I, however, used some data recovery software on this card, which would show some data, but not all. Can you suggest me some good software to recover data from this card?

Hello. Did you ever figure out how to get the data off your SD card? I am in the same boat. I thought I was safe having everything backed up on there, but, nope...
Thank you

yep i did the backup ,formated in phone and the computer i think i will return my phone
Did you try another sd card? may be broken. I have not found any problems with mine yet. I used computer to transfer the files, but I can access them from the phone, transfer some pictures from phone to card directly as well and some programs store data on the card, no problems yet and in the past most problems I had were related to Android SD card permissions, not phone's issue and somehow fixable.
