I have been searching high and low for hours and cannot find anything related to my situation.
I am replacing my V20. The SD card is encrypted. I attempted to decrypt it on the V20 but it would hang at 1%. Sat there for several hours. I read one post that said I needed to disable screen lock and reboot the phone. I disabled screen lock, did NOT reboot, tried to decrypt gain, sat over night, didn't go past 1%. Rebooted phone, now I no longer have the option to decrypt the SD Card. I reenabled lock screen with same password and still no option to decrypt. I tried using Cryptonite to decrypt it, I get to a point it asks for a password, but then gives me an error stating there was a problem with file permissions or the password. The V20 is not rooted. Hesitant to root it and risk losing all of the encryption keys. Closest thing to a solution I have been able to find is to copy the files to a PC, format the sd card, encrypt it, copy the files back, then decrypt. This seems quite hoakie to me.
PLEASE HELP!!!!
The long way of transferring data to and from computer seems to be the only option

The problem is, the data is still encrypted and unreadable to the phone or computer. If I copy the encrypted files to the PC, format the SD card, encrypt it, then copy the files back, won't the phone double encrypt the files? Or will the phone recognize they are already encrypted and "unlock" them?
If I go this route as a test, will DD in Linux make a sufficient enough bit for bit copy of the SD card to restore it as if nothing happened? Is there a Windows alternative that would work just as well?

I think what Still_living714 meant was that you have to use the V20 to access the SD card and copy the data to a computer using USB or a network connection through it.

I understand that. But the V20 isn't even able to read the files even though they were encrypted on that device. Most of the files are not readable. So copying an unreadable, encrypted file, from the device via USB, to a PC, will still result in an unreadable encrypted file on the PC. I then format the SD Card on the V20 and reencrypt it. I then copy the still unreadable and encrypted file back to the SD Card which is in the same V20. Now the V20 is going to encrypt that file again making it double encrypted, correct? Or will the V20 recognize that it is already encrypted and give me access to the file since the lock screen password was reset back to what it was before this fiasco started?
Maybe I'm just not explaining the situation correctly.

Umm, that's not how the encryption on an external SD card works on android.
If the OS fails to decrypt the card, the whole thing is inaccessible. Android encryption is not a "per file" encryption.
Forget all of the double encryption nonsense. No file is ever double encrypted you simply copied encrypted files from the SD Card to new device/pc, and copied them back to a formatted and re-encrypted SD Card in hopes you can decrypt them. Thus, is there a way to decrypt it (period)? That's the real question!!!!
So, can someone answer the real question. Especially, I'm having the same problem after upgrading to a S10+ from a S8+ that I traded in. So, now I can't read nor access 14.3 GBs out of 16 GB SD Card; which is unacceptable.

Hi All,
Can anyone recommend a good encryption program for me? I'd just like to be able to take a single folder on my SD card and encrypt it.
TIA
I like TrueCrypt. It is open source and user friendly.
I love it too and use it on my PC but I do not think it is available for WM is it?
I don't think it is available for WM either, but you could probably encrypt a folder on your sdcard from your desktop (with your phone set to mass storage mode). I don't know if it would work, I've never tried.
I dont want to encrypt the entire thing. AFAIK, if you do and you reflash your phone, your whole sd card is toast.
IIRC you can encrypt a single folder on a flash drive using TrueCrypt, so I would think you could encrypt a single folder on your sdcard. Perhaps you could create and encrypt a folder on your desktop and move it to your sdcard.
As far as flashing a ROM wiping out your sdcard, I hope that isn't the case.
Thanks for that but it wont help when I'm traveling and need access to the info.
No problem. I hope you find a solution for your needs.
hello everyone i hope someone can help i dont what happened but now at the top there is a SD icon with a red ? it says mounted read only can not get it to work the only thing i did was i use the tethering for my laptop nothing eles was new thanks for all and any help.
Ooh boy where to begain, lets start by recovering your data manually as the cause of it may depend on the quality of the card itself which ill cover after your data is safe. If you try to solve it now you may just lose all your data. Keep in mind changing base permission manually via chmod does not solve this problem as I have tried and very aware of it
Now there are 2 ways you can access the data. First is via SDCard reader and second is via device. Now keep in mind depending on the severity of the problem the card may not even be mounted at all in that case you can access it from /mnt/sdcard/. To copy and tansfer it you can use CP command in terminal but for you I suggest you use File Manager it will save you time if you don't like console. What you want to do now is copy data from /mnt/sdcard/ and paste it /data. You can make new dir (mkdir) inside "/data/" temporarily and then have it transferred there and then unmount the sdcard and put new SDCard and have it transferred from /data. Now depending on the size of your backup you may have to do it few times.
Once this is done as you have your data. Format the SDCard from computer with card reader thoroughly, if you can't then do it from device. If not then go in recovery and format and do force partition. Now once you have access to your card you need to verify why this has happened. Now make sure the SDCard is legit by testing (R+W+V) for data integrity, you can use H2TestW. If it passes you can count out bad cell which is physical defect. Now depending on the quality of the card it will also control how data is allocated and if it will be facing data corruption by erasing itself (Blank SDCard) or by corrupting the file allocation table and reading as UFS (Unsupported File System).
In that case you can still manually reconstruct the data structure as the data is not overwritten but you have to allocate the device to access the raw data. But that is not for you and not for faint hearted.
thanks so much for the info i should have said that i tried the card in my wifes mt4g and it works fine i can see the data if i plug the in the comp but i do have to plug it in after i tell it to remount then it works i dont know if that help and should i still go ahead and do what you said thanks so much for your help.
well just wanted to say i think i fixed it all i did is hooked phone to pc and copied eveything off the SD card and put it on pc then formated the sd card on the phone then put all back on its seems to to be working i wanted to say thanks to black shelf for his info thanks.
Ok So I am here because I've posted in other places in these forums with no replies yet, So it would be better to create a thread specific to my problem.
I have an Omnia 2, thinking of acquiring the Fryo 2.2 OS, not specific about wether I want what version but here are the problems I come across before being able to install it.
1- plugging in my phone under Settings -> My storage will not show my storage on my computer, having the external SD option will show my 16GB SD card.
2- Backing up. How do I back up my storage if I can't see it on my computer? When I turn on active sync a blank storage appears other than my SD card (assuming its the internal storage) but the size seems rather small (167MB). I've been reading peoples' posts and I'm supposed to have around 2GB I believe, and either way the files I'm trying to put inside for the android OS don't seem to fit there.
3- Partitions? How can I set those up for both the internal and external storage? Is there a program or feature to do so? My SD card under properties says FAT-32 so I'm not sure on how to do it IF I need to.
4- Using a W7 computer, so that knocks off any ubuntu installations, and also link is broken for Almars Beta 1 file that I was thinking of using for an SD installation.
Any help would be appreciated, I've had this phone since 2009 and I'm really hoping I can come across some help to make it work since I do want to keep this phone for a bit longer before I spend more money on a different cellphone!
Thank you!
Try out the new CyanogenMod from the link below.
http://windows.modaco.com/topic/346446-cyanogenmod-beta1-omnia-2-updated-02122011/
It has the SD Card auto installer, try it..
Back up data on your SD card first and then format your SD card within the phone and then use auto installer to install it.
As you said your computer wont detect the My Storage, try the steps below..
Transfer your data from My Storage to external SD Card, then connect your phone to computer using My Storage mode in settings.
Download Mini Tool partition wizard and format your My Storage (Mini tool partition will be able to see your My Storage even though your computer doesn't).
After format, your computer should be able to detect My Storage.
Now copy the downloaded android files to My Storage and run the auto installer as instructed in the ReadMe file inside the download package.
PS: Don't forget to backup the data on SD Card to your computer
Hope this helps
Ok so what you meant by taking things from my storage is going to file explorer and basically copying everything from the "my device" to the SD card?
Just want to make sure because if it doesent work then I haven't gotten anything backed up right.
Went to file explorer -> copied everything in the top folder which is application date, connMgr, doc and setttings, program files etc. is this all thats needed basically?
Thanks
P.S some of the things I tried taking like global.txt or exe couldn't be copied because of violations or some weird error, is it alright not to have those?
Update: My storage is still not revealed by the mini tool partition program, went under usb settings -> my storage and refreshed disk information, nothing shows up ugh it might be impossible for me to do this after all....
nobody can help me in regards to this? well then I guess a new cellphone is in order
grrrrr I should've gone with a iphone 3G or BB 9700 at the time instead...

I guess you will have to reflash the ROM again since your problem seems to be unsolvable. My suggestions is to flash a stock 6.5.3 ROM before you transfer the auto SD installer.
I was following this guide to root, install a custom recovery, and then flash a ROM onto my phone. I rooted successfully and created a back up. I then copied the backup onto my external sd card. I then put the custom rom onto my sd card and entered recovery mode on CWM. I wiped my device and then realized that the custom rom was the incorrect file. I then went to restore and it gave me an error md5 mismatch. I then went to restore of external sd card and it said it could not find the directory. I then went to restart phone and CWM said I was not rooted anymore and asked if I wanted root access and I hit yes.
My phone will not start and just remains in the Samsung loading screen with an unlocked graphic with the words "custom" under it. I am able to get back into CWM recovery but nothing else seems to work. I appreciate any help I can get. Thanks

You can either use a MicroSD to SD adpater and the computer's card reader to copy a ROM over and flash it, or ODIN back to stock, and start over.

Clueless here. Made a post about it.
I just discovered today more than just myself are unable to plug the handset into a computer to exchange files. I can get things off the phone onto the computer, but not vice versa.
Also the handset itself is fussy when it comes to viewing it's own external SD card. It would seem it doesn't take much for it to disappear, once in recovery.

This phone does not support mass USB storage. It uses MTP and PTP protocols. This information is available in several threads in the forum. Now, of course, even with MTP and PTP you should be able to still transfer files from a PC to the Ext. SD card considering you have the correct drivers. Perhaps your SD card isn't playing nice with your phone? Have you tried removing the card from your phone and transferring files to it dierectly from you PC via SD slot or card reader? Have you tried other brands? I find Samsung cards work best, but that is just me, This will help to see if it is the phone (possibly cable) or the card that is having issues.
Also, you can check this out. It supposedly enables Mass USB storage for this phone...though it still says it doesn't work for the Ext. SD card. I have never tried it, so if you do it is at your own risk but maybe it will help? Good luck.

The app says it is for the SIII, but people have reported it as working with the S4 as well.

I am too happy to experiment like that. The AT&T S4 running GoldenEye with no add ons is the best darn handset I've ever enjoyed. I love being rid of the bloatware. I don't miss it a bit. I will fuss around with the SD interface as I do have resources like you mentioned, I can try a different chip. I didn't consider that a bad chip would cause the computer to consider the entire handset as "read only", yet you suggest it's possible?

Anything is possible and it would be a simple way to maybe help identify where the problem lies. Better yet, take your sd card out of your phone and try a transfer. That will let you know if it has anything to do with it. If it still doesn't work, it more than likely has nothing to do with the SD card.
Can you transfer files from your External SD card to your phones internal SD memory and the other way around (via a file manager on your phone)?
If you can, I can't see how it would be a "read' only problem.

I should unhook my phone from the 3.5mm jack and look into this. As I type, my S4 is piping in my playlist to provide the wife and I musical background for our activities. I remember using "Root Explorer" recently to delete a nandroid backup, and to move said playlist off the SD card into Phone memory. The "write protected" error showed up directly after building this playlist, using the computer to organize it. It's brand new, and as a good troubleshooter, we always look at the last thing you did different. I used the "windows explorer" to edit my playlist on the phone while it was plugged up together.
It's turning out to be a bigger deal than just myself, and I should pursue your recommendation for testing and reports, but it's not broken enough to fix and it's Sunday night, and the music is more important at this juncture.
Edit:
I powered down and then removed the Micro SD, and when I powered back up, it showed that cool padlock icon with the label "Custom" screen during boot up. I hadn't seen that screen on boot up since I used Casual to get a TWRP recovery.
I tethered the handset to the Desktop and opened the windows explorer. Obviously it just showed phone this time, instead of phone and card. I tested copying files and it worked fine, the "write protected" error was gone.
I unhooked, powered down, put the micro SD card back in, powered up and noted the boot up screen was back to normal. Tethered up again and voila! Files can be written to the phone and or the card and no more "write protected" error.
Funny little fluke. Problem solved. Curiosity remains.
I have a Samsung A3 (2017), there were VERY important files on it, and when I returned the phone to factory settings, I either did not see it, or there was nothing, but it turns out that my files on the memory card were encrypted. (I honestly don't remember that I encrypted them at all) And after resetting the settings, I can no longer just decrypt them like that. Now they are on a laptop, and the old memory card that was in the phone at the time of encryption has been lost.
I tried to restore them through another memory card, but to no avail. I found a list of programs for decrypting files encrypted by ransomware on the website. Can any of these programs help? I downloaded the first one, and there it asks for extension files that I don't know. My encrypted video has the mp4 extension.
And here's the question: is it possible to decrypt these files somehow? I mean, maybe you can find out for a start what algorithm Samsung encrypts files, and then I don't even know how to decrypt them with brute force. These files are VERY important to me.
P.S. Sorry my english is bad and I used google translate.

Hi,
I had same issue...did you find a way to solve your problem?
