Model: Samsung Galaxy S3 AT&T i747
Hi!
I was forced to encrypt my galaxy s3 in order to receive corporate emails on my phone using the stock email app. However I never imagined that encrypting the phone would literally lock the memory and options to customize the phone.
I tried to root the phone to benefit from more flexibility and also debloat the phone. However during the rooting process, I could not mount /emmc/ when using ClockWorkRecovery in the startup menu. Based on what I found on the web, I figured it was due to the encryption.
I then tried to factory reset the phone to get rid of the encryption but I simply can't hard reset the phone from the OS or the startup menu. When doing the reset from the startup menu, the errors are "Can't mount /sdcard/". The reset continues but when the phone reboots, all my applications and personal data are there and the phone is still encrypted.
I read a lot about flashing a custom recovery via flashboot or ADB but I am reluctant to do it without guidance from the experts (you guys).
I deleted my corporate email account (It is my personal phone, I am not required to install exchange on it).
I tried to use an external sd card but as soon as the phone recoginizes it, I have to encrypt the card as well as a result from the corporate policies. I ejected the card and did not encrypt it.
I am new to android (long time iPhone user) and I would really appreciate your guidance on the methods to factory reset my phone or a different technique to get rid of the encryption because I am really stuck right now.
I have never encrypted an Android phone before. But maybe your response to these questions will serve as a "bump" to this thread.
1) What method did you use to encrypt the phone? Stock or 3rd party encryption?
2) Doesn't that same method also offer you the offer to unencrypt the phone?
3) If you used a stock method of encrypting the phone, then I'd assume your provider (AT&T?) tech support should be able to help you unencrypt it.
Eddie,
Thanks for your response.
1) I used stock method for encryption
2) Decrypt the phone is not possible apparently,only way is to factory restore the phone apparently
3) I went to the AT&T store and they were unable to factory restore (using the standard methods). They offered an exchange but since I purchase over the phone at a discounted price, I have to do the exchange using that method. Before shipping back the phone, I was wondering if I could fix it myself with the help of knowledgeable people.

I have never used the encryption but if the phone can turn on and is usable, cant you go into the encryption settings and turn encryption off? then you should be able to do anything (may be best to start with a factory restore first just so you have a fresh slate to work with)

1ofaKind,
Had EXACTLY the same thing happen to me. Encrypted my S3 in order to access work exchange server. Tried CWM but cannot mount /emmc/ problem after booting into recovery. Have not tried to factory reset yet as I am wanting to learn more before I go that route. But basically I am in the same boat as you. The only difference is I was not required to encrypt an external SD card when I put it in my phone. Read about flashboot as well...maybe the only way to actually factory reset after encryption??
Sorry I cannot offer any solutions at the moment...but I will keep scouring the forums looking for a way.
If I learn something valuable, I will try to post it here to help ya out.
EDIT: Maybe you have read these threads, but there is some decent info in them. http://forum.xda-developers.com/showthread.php?t=1451655 & http://forum.xda-developers.com/showthread.php?t=1392037

Look into using Odin to restore a factory image.
Sent from my SAMSUNG-SGH-I747 using xda premium
I'm in the same boat here - had to encrypt my GS3 in order to receive corporate (Exchange Server) emails. Now can't update the OS on the phone which is more important to me than receiving corporate emails on the device.
Can someone tell me how to decrypt (UN-encrypt) the phone? Everything I've read says that a factory reset won't do it.
Please help!

Has anyone tried this? If so, did it work?
I clicked install rom from sd card in cwm selected f/w which i had copied into internal memory. Did factory reset in recovery.
Odin it back to stock.
This might be too late to help you guys, but here's what worked for me. I odined it back to stock. Then I went into recovery (volume down, power and home button) and selected wipe data/factory reset. This does of course erase all your data, so try to copy whatever you can onto a computer or something before doing this. You should end up with an unencrypted storage.

After you hit start, unplug then replug the usb from the computer. I had some issues with it not recognizing it either to flash stock, but when i messed with the cord, it made the noise that i unplugged and it started working. Same thing with the root injected, only this time i fully unplugged it when the fiddling with it didnt work. Make sure you replace it into the same com port.
so, i seem to be having the same problem as all of you, only i encrypted to protect my data from agents. So, right now, i am *hopefully* :fingers-crossed: installing the root injected JB now. I had many issues. TWRP and CWM were no help, couldnt see phone to add new roms to it. ODIN was the only hope. I booted into recovery after going back to stock, did a new factory reset and am installing the stock with root. When i let it boot, it didnt go to encryption this time, but the first time i flashed the stock, it did. This is a mess to say the least.
EDIT: YEAH! done. No encryption and i got root. i used the image from here: http://forum.xda-developers.com/showthread.php?t=1968625 DLK3 worked for me. Good luck. i hope this helps. Ill be happy to explain more if you want.

Factory reset encrypted phone
hi,
I'm using CM11 as a rom.
I didn't want to reinstall stock rom, just to root it again later.
Installing updated version from external SD didn't work (updated the ROM but no decryption)
Tried to factory reset from recovery - didn't work, as the internal storage is encrypted it can't mount /sdcard/
however, from within settings menu, in backup&restore there's an option to do a factory reset - this is formatting internal memory altogether.
worked like a charm.

I understand this is very old but I am going to make a note here in case anyone else gets into this problem. When you go back to stock, do the factory reset using the STOCK recovery. Don't install TWRP or anything else until you have cleared the encryption. At least, that's what worked for me.
So, this is my first Samsung device, longtime HTC user. I was cocky and thought I could go ahead and delete system apps that I thought were safe to delete. Apparently, I was sorely mistaken.
I am now caught in a bootloop. Luckily for me, I can get into the system and do a few things before it reboots. I was unable to fing factory images for the s6 edge, so, I have another idea, but I need someone's help.
I was thinking if someone could make a backup using titanium backup of all their system apps and share it with me, I would attempt to run the restore option in TiBu to remedy the issue. If anyone could do this, or has a better idea, let me know. Thanks in advance, and I apologize for needing something so trivial (smh).
if you can get into the settings menu and do a factory reset, that would fix it..
also, try calling t mobile, and ask tech support how you can boot into recovery, and there should also be a factory reset choice in there..

I've done that, the phone simply reboots itself. When I try to boot into recovery, I don't get that distorted green/white screen everyone else does, it flashes real quick then goes dark, nothing more. I've tried the vol- 4 times, power, vol- 7 times power, wait, power combo as well, it does not factory reset my device.
I would still call t mobile and ask them how to actually boot into recovery.
There has to be a way to do it; I would turn the phone off completely, then boot into recovery using the method t mobile suggests..

I really appreciate your help in trying to get me into recovery, but I have tried everything. I've done the release after the buttons stop blinking, don't release until you see blue text (which I never do, there is never blue text at the top of my screen). I also work for T-Mobile, I have access to the files customer care would read you if you called in. I am at work right now lol.
Honestly, all I need is a zipped titanium backup of system apps (just the app, no data) that I can get onto the phone and try and restore.
I don't mean to sound rude, but this isn't my first rodeo. I've been attempting to get a logcat to identify which error is causing the device to crash so I can ask for just that one app (I can't get the log though, always hangs on waiting for device, even though I can execute other adb commands). All I need is that TiBu copy.
Edit: Wow, I finally got it to factory reset. I'm not sure why it didn't work before. I tried the same thing countless times with no success, but I finally got it.
Again, I apologize if I sounded rude earlier. I really didn't mean to be.
not rude at all bro, as you know, there are so many different levels of "knowledge" here, that I try to use the lowest common denominator when helping folks out, but you obviously know what you are doing!
Glad to hear you got to factory reset menu; that should fix you right back up!:good:
I was in the same boat as you. Rooted, removed system apps, got back to Recovery Screen, but a Factory Restore did not bring back the apps that were removed. Tried Kies, but it would not work last night. As of this afternoon, Kies will now work. Just did it a few minutes ago.
Use the "Firmware Upgrade and Initialization" option. You'll need the Model Name and Serial Number, both of which can be found on the Box, or in the Settings menu if you can get there.
Got a little too cocky with my limited knowledge of messing with androids, decided I wanted some nifty new locking sounds for my phone. Replaced the Lock and Unlock ogg files and wiped the dalvik, as the guide I was following said to do. It also said to fix permissions, but that was a vague statement and is most likely causing my problems. Anyway, now I can't download anything from the browser. I've tried stock/FF/Chrome/Dolphin and a few others, none work. I tried using the Download all files app and got a download failed (disk failure) error code. Not too worried if I have to factory reset, but wanted to try here to see if anyone could help before I nuke it.
Try flashing a stock rom from sammobile.com using Odin. After flashing, boot into recovery and wipe cache only, reboot, and see if the phone is back to normal. If not, a factory reset may be the only solution.

If all else fails, then STOCK ROM IS YOUR KEY TO PHONEAGE! Either go here and click on the most active post which will ultimately send you over to SamMobile. Just remember... be sure to flash the correct model number as stock firmware might damage the phone even more by being careless about choosing something which is not correct. Always check twice before getting your flash on!

I think there is an option actually called "fix permissions" in TWRP recovery under "Advanced"
Good luck!
If your phone is running a stock ROM, reflash the same ROM with Odin, wipe cache but not data and you should not lose anything.
Hello.
I was fiddling around with my phone today and wanted to clear the cache from the Recovery.
After rebooting tho it showed me a message (note that I never toggled OEM unlock or even accessed recovery/download mode or anything before today):
fail to open recovery_cause(No such file or directory)#

And after a minute or so the Recovery showed up. I went to delete the cache, all went well until I was met with the same message at the end:

Should I worry about anything ? The phone booted normally but I'm a bit skeptical about that error (maybe the cause of my as of late noticeable battery drain ?) and any help is appreciated!
EDIT: Another thing to notice is that when booting into recovery, it seems the phone is trying to install an update which isn't there, and only then takes me to the recovery menu.

Everything you said I think is normal. So don't worry about it. It still clears cache or whatever you do.

I see, thank you
It's a weird bug so that's why I was worried. I did read some reports that some users couldn't wipe data due to this in the Recovery and it got me a bit worried.
Let's hope it's just a stupid bug and nothing more. Thanks again!

Hi there
I have this issue. I cant factory reset the phone as it says MDM does not allow this.
so I used odion to reload the Stock Firmware on these but now I have FRP on this.
as it's a work device & dont know the user that last used this phone.
even after the flash I still have bcb message
Is there any other way of sorting this out.

When you get into work phones, things get really ugly. Can you wipe data by flashing just csc in Odin?
Similar problem with S7, it just keeps rebooting
I have an S7, I have the same problem, the phone started freezing and rebooting every minute. So decided to Wipe out the cache and do factory reset, saw this message "E:Failed to clear BCB message:failed to find /misc partition"
The phone never goes past the Galaxy S7 Android logo screen most of the time, if it did manage to go pass, it freezes after 2 to 3 mins and reboots.
So I tried and successfully rooted, installed TWRP, took a backup and tried to wipe cache, it failed.
formatted the and tried to restore from backup and it failed, as it never went pass the S7 logo screen.
so I tried Lineage OS 17 and it worked like a charm
then tried back to Android 9 ROM from Samsung, it too started to hang and freeze - If it was an Hardware issue, I would expect Lineage OS to freeze too.
I think and it looks like Samsung is forcing its customers to buy new phones .....
Please help
thanks

Exactly the same problem
Hi guys,
I exactly do have the same problem. I upgraded from LineageOS 16 (which was working smooth.y ) to LineageOS 17.1 and faces a problem wit IMEI, So I tried to revert back to Stock ROM, flashed via ODIN latest version.
I could flash the stock ROM (doing NAND Eras and Re-Partition due to Vendor partition). But after reboot, the ROM won't boot and stuck with SAMSUNG screen blinking.. I managed to access the Stock Bootloader and could do a full factory reset, but I still get the error message like above.
If anyone has an idea how to solve...
My sister had many randomly chrashing apps and ask me how to fix it.
In recovery the same message was printed. BCB and /misc ...
Well I tried to clean install stock rom (A5 2017) with odin, but the user data was never deleted ... Don't know how to use odin ...
I have then flashed lineageos and now there are random reboots and apps are only crashing sometimes once opened.
I attached a crash log. The app crashin is called antennapod (https://play.google.com/store/apps/details?id=de.danoeh.antennapod&hl=de&gl=US)
Anyone knows what causing these? And if they are still related to BCB and/or /misc?

I would not mind rebooting from factory settings, but my Whatsapp account was still linked to a number that I don't have access to anymore. I do not want to lose the last conversation I had with my dad before he passed away even though I have the back up in my google drive, I know it is encrypted and cannot be retrieved unless verified through the number.
Have I tried getting my number reactivated/ a SIM with my number reissued? Yes, but Vodafone (specifically VOXI) said it was not possible.
Is there any way to contact Whatsapp directly? I did, they were not helpful.
I am posting here because I have honestly scourged the internet for a possible solution, but I am still confused about what my options are here.
Hi,
I'm not specialist but what about reflash the fastboot ROM with xiaomiflash and the save user data option selected?
Not sure about myself so wait for other ideas/informations but maybe it's a 1st way.
Good luck btw!

I can confirm that the reinstallation of the last available Rom, previously copied to the SD card, does not erase the data and unlocking the bootloader is not necessary.
Of course it is always advisable to keep your fingers crossed ...
Good luck.

I tried flashing it with MiFlash, but I got an error saying my bootloader is locked. Specifically, it said: error: Erasing 'boot_a' failed (Device is locked. Cannot erase.)
You could try to do this https://forum.xda-developers.com/mi-a2-lite/how-to/guide-how-to-unlock-bootloader-erasing-t3878453 but it seems risky. If you fail to do it correctly it might erase your user data and with it all hopes of restoring the desired data.

Hi everyone, so I tried flashing it through MiFlash and all. First, I had the bootloader locked problem. After briefly fixing that though the ./fastboot.exe oem unlock command, I was able to flash it. Nonetheless, despite ticking the save user data option, it factory reset my phone .. at least I tried, I hope this info is useful to everyone else tho :'(
