General :: Jelly Bean Full Disk Encryption Password Altered After Swapping SIM
Sep 1, 2012
I am running Android 4.1.1 on a Samsung GT-I9250M Galaxy Nexus.
Third, I have two carriers: a Straight Talk Unlimited Prepaid SIM (United States GSM/HSDPA) & a Claro Prepaid SIM (Honduras, GSM)
1) I installed the Straight Talk SIM in the phone.
2) I installed the battery in the phone.
3) I powered on the phone.
4) I enabled full disk encryption, choosing an easy-to-memorize password.
... over two weeks, i successfully decrypt the phone on boot 30 - 40 times with the password ...
... then i travel to honduras and purchase a Claro SIM ...
5) I powered off the phone.
6) I installed the Claro SIM in the phone.
7) When prompted to "type password to decrypt storage" I enter the correct password.
8) I am prompted to "try again."
9) I enter the correct password.
10) I m prompted to "try again."
11) I powered off the phone.
12) I installed the Straight Talk SIM in the phone.
13) When prompted to "type password to decrypt storage" I enter the correct password.
14) I am prompted to "try again."
15) I enter the correct password.
16) I am prompted to "try again"
I have tried booting with the Straight Talk SIM, the Claro SIM, and with no SIM. I have tried removing the battery. I am able to boot in Recovery Mode. However, performing a factory reset is not a viable option for me. I need to regain access to my phone. Why would the encryption key be altered by the SIM change? And wouldn't reinstalling the Straight Talk SIM be enough?

I set a password to encrypt the disk on my N4. When I reboot the phone it ask me a password with a standard keyboard.
My question is : can we change this keyboard for another one or at least its orientation?
the cause is that my screen is broken on the lower right coin and it block the "Done" button. annoying...
The TWRP keyboard to decrypt the disk should be fine (its "done" button is larger enough)

It started with powering on one day and a list of command prompts came up. Brand new model N 9810. I never saw this before on a droid i have had them for yrs. The list of command prompts seemed odd: Adb update..
Debug error report...
cache report...
Clear partition, wipe cache...
Factory reset sdk...
All of these items sounded odd to me, so instead of choosing an option bc i wasnt sure what would happen, i pulled the battery.
I put it back in and the phone came up in command prompt mode again, i was really concerned why this happened. I am not a tech person, so i thought, is my phone hacked? I ran root checker, both said no root or SU identified, but it said busybox was installed??

I have a Google Nexus 4 (rooted, of course) and I'm using the native phone encryption.
There is some information that can be found, revealing that google uses the native linux dmsetup tool for this.
Now, just in case anything goes wrong, I'd like to have a backup of the encryption master-key,
that I could use to restore the dm-crypt header.
On a normal linux system, this would be easy, only one call to dmsetup and I'm done.
However, I just can't find any info to do this on android.'
The UI doesn't offer this option (as is to be expected) and I just don't know how to do it by using adb.
I've opened a root shell session and tried some commands (dmsetup, cryptsetup, some calls to "vdc cryptfs", etc...), but I just don't find a way to do it.

When I go to system settings -> security -> encrypt phone, with phone fully charged and plugged in and a suitable PIN set, the phone reboots back to lock screen but does not appear to do anything to actually encrypt the phone. After reboot, the option remains looking identical in the settings menu. No error messages or the like.
The lock screen works fine (PIN required), the PIN is suitably long, everything is updated, etc.
I'm not sure what the issue is. I rooted & changed ROM immediately on getting the phone (it's new), so I don't know whether it would've worked w/ stock bootloader / rom / etc.
I'm running:
Nexus 4 (android 4.2.2)
ParanoidAndroid 3.65 (pa_mako-3.65-20130712 + pa_gapps-full-4.2-20130710)
TWRP bootloader (openrecovery-twrp-2.6.0.0-mako)

I'm on gs2 I9100 cyanogenmod 9 and can't find a solution to encrypt internal databases like sms, call logs, contacts... ( so in /data).
No problems with documents in container created by luksmanager. But i wonder is it possible to make a sort of preboot script who mount after correct passphrase a luks container who is symlinked in /data ? Because android ics built in encryption installation stop at beginning.
Is there now new method or app to encrypt full or partial phone? Maybe new encryption function or improvement in JB? Pattern/face unlock fixed?

I'm interested in encrypting my phone (rootbox 4.2) including the external SD Card (if that's possible..?) but i need to know if you do it, then let's say you take that sd card out of the phone and plug it in your pc, how do you access the data? And is that still impossible to unencrypt the phone after it was encrypted (i mean on last android versions)?

So the title may be a bit hard to comprehend but the gist of it is that I turned on full device encryption and since then when I transfer the pics off the phone to a computer they cannot be viewed. The message I get is corrupted metadata, the sizes on them seem right, I have not tried to view the exif data through a utility yet to see what exactly is corrupted.
I can still see the pics on the device, and share them online, but when I copy them off of the device they are broken. I've tried a couple of jpg recovery tools without any luck.
Most similar posts I've seen related to this is a corrupted sd cared (but this is on the internal one and only started after I turned encryption on).
And to confuse things a bit more, if I email the pic off it works correctly. So the problem seems to be just directly pulling them off the device, or browsing them when they are on the phone but connected to a machine. Same thing happens in linux and windows with various software.

If one enables full device encryption in Ice Cream Sandwich, am I correct in assuming that that the internal SD of that device is now not going to be available in the CWM recovery mode? And even if it was, the root fs would not be available? If so, this pretty much would make CWM flashing your device near impossible?
Does CWM even work if you use FDE? Or is it planned/
The question I guess is, when do you input your encryption password? Is it some pre-boot step?
I really want to enable device encryption but I can't find enugh details on how it works.

I recently added an exchange account which I then removed. Now my only lock screen security option is "password". I'd like to use pattern lock again.
I don't have any device administrators nor any exchange accounts anymore.
Is there any way to restore the settings to what they once were?

ANY email address I put into the email client preinstalled on the phone ALWAYS says username/password incorrect if the password has non-alphanumeric characters in the password!!! I have THREE email accounts that REQUIRE non-alphanumeric characters in the password and ALL OF THEM experience the username/password incorrect error message!!!!! ALL email accounts WITHOUT non-alphanumeric characters in the password work!!!!! Googling the problem brought up NOTHING!!!!

I'm attempting to support my daughter with her GS3. The device is currently in SAFE MODE and and the storage is nearly full. She also has said the device has been rebooting on its own. She is currently deleting apps she is not using. She does not have an SD card installed. I know how to get around my BlackBerry, but am unfamiliar with the ins and outs of Android. Her device is the Sprint version running 4.3. How to get her device back in top running condition.

I recently received the OTA update to my Eris and am loving the new interface. However every time I want to unlock my phone I am now required to enter an 8 digit password as opposed to the screen pattern I was using prior. From messing around I realized that this is due to the fact that my company's exchange account requires SSL encryption and therefore requires the password be entered to unlock the phone. My question is whether there is a way to keep my email but only require the screen pattern to unlock my phone? I know iPhone users at my company that are still fine entering their 4 digit code so have to assume we should be able to do the same.

I am developing an app that uploads files to an FTP server, and the app will have the ftp user name / password in the code. I'm investigating making the FTP user name and password as secure as possible (including an encrypted value for each in a strings.xml and decrypting in the app when it needs to connect to the FTP server).
My concern is this is not actually secure at all, it seems someone could unzip the .apk, decompile it, view the strings.xml and java code that decrypts it - and thereby obtain the ftp login info.
So my question is.. am I approaching this wrong way? Is there a standard method of ensuring passwords that are hard coded into an app can be secure? (note - in this case this is not a password a user of the app would enter, the FTP password is universal to all that install it so it is included in the app).

I have a Coolpad 8720L with its own interface built upon 4.3 Jelly Bean. It's not very good, and I'd like to install stock Android instead. How do I do this?
I heard that I have to root the device, and then find a ROM for stock Jelly Bean to load onto the device?

Best way I could describe it. On ICS the dialer would allow me to type a number and come back to it later, now when I multi-task the number disappears. I am running 4.1.2 on a HTC Desire 300, and the dialer is stock to the best of my knowledge.

The jellybean box itself turns on and the home screen loads up. I select the page where all the apps are...select xbmc app...sometimes it flicks back to main apps page other times the screen turns black/blank. I can't get further than this page....my box has worked perfectly for the past 3 months since purchasing. I can't get into the settings page as I can't get past the blank .

so i've recently downloaded installed and bought faceniff.i really like the app, but i was wondering if there was a way to make it show the full password.i've decompiled the apk, and i have looked at it for a while but i cant seem to make sense of it all. i have some experience in C++ and C, also PHP VB.NET etc but not in java.
when the code is found it shouldn't be too much work, only thing i need is finding the code that puts the ***'s over the middle of the password.

After I flashed a couple roms I couldn't boot jelly bean anymore and I noticed the error in recovery: E: Cant Mount /efs, when installing. But I could still boot ICS but not jellybean. I still had my IMEI and could make calls but could not boot jelly bean because it couldn't mount.
Sometimes when installing a rom something goes wrong and it changes the partition type of /efs making it unable to be mounted. The partition is usually from ext4 to swap.Most likely this will work on your phone but if it doesn't and your phone stops working I am not responsible.
If your like me and you couldn't get jelly bean to work then flash your device back to ics and it should boot. Once your booted inside of ics we can start the process.
Pre-Setup:
1. Be rooted and have a custom recovery installed.
2. Be on Ics and it boots.
3. Your need to have a Jelly Bean rom like Cyanogenmod on your sdcard.
4. Have adb installed on your pc and usb debugging on in your phone/tab.
Now that that's done its time to start.
Part One:
1. Boot into recovery.
2. We need to find the efs block location.
3. Go to mounts and select efs
4. It should say unable to mount
5. Go to advance and make a recovery.log
6. Put that file on your computer and open it.
7. Look through the file and you should fine something like this around the beginning of the file:
E:Unable to mount '/efs'..Actual block device: '/dev/block/mmcblk0p3', current file system: 'swap'..My location is /dev/block/mmcblk0p3 But yours could be different! Most likely the difference will be instead of it ending with a 3 it will be a different number. I will be saying /dev/block/mmcblk0p3 if yours is different just change it to your location.
*WARNING* Sometimes when you copy paste into adb it will auto run the command without you pressing enter. If your location is different then mine and you copy past and it auto runs it could be BAD so to be careful if you want to copy past. Copy the command paste it into Google make the change and copy that and paste into adb
Part Two:
1. When your inside recovery connect your phone to your computer and get into a adb shell. (Sometimes it will take awhile for adb to recognize your device so be patient.)
2. Once you have adb access its time to start entering the commands.(Again my location may be different the yours! Most likely the difference will be instead of it ending with a 3 it will be a different number.
Part Three Inside ADB:
1. su
2. dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img
3. mke2fs /dev/block/mmcblk0p3
4. mkdir /efs
5. mount -t ext4 /dev/block/mmcblk0p3 /efs
DONT REBOOT PHONE
Part Four On Your Phone:
1. Now /efs is mounted don't unmount it
2. Do a factory reset
3. Install your Jelly Bean rom
4. It should install without any errors
5. Boot your phone
6. If everything went well it should boot.
7. After it boots your signal notification most likely will be gray and internet or calls may not work
8. To fix just install gapps and it will be fixed
There you have it if everything went correctly your efs should be working good and you should be able to go back and do your normal rom flashing.
If jelly bean boots but you don't have phone do this:
1. Go back into recovery and get adb access.
2. su
3. mke2fs /dev/block/mmcblk0p3
4. mkdir /efs
5. mount -t ext4 /dev/block/mmcblk0p3 /efs
6. dd if=/sdcard/efs.img of=/dev/block/mmcblk0p3 bs=4096
