[Howto] Different PIN on lockscreen than for device encryption

Hi,
Android 4 / ICS has a good security feature: full device encryption. But it's implementation has a big usability problem: you have to use the same password for device encryption as on the lockscreen. Meaning you have to enter the complicated encryption password every time you want to access your phone
Chosing an easy password would make encryption worthless and Android limits the lowest complexity allowed for encryption.
Technically these passwords are two completely separate things. It's just the Android UI that mingles this. So it's time to hack and separate what should be separate!
Here is how to do it, rooted phone needed:
Make a backup
Enable USB debugging that you have a backdoor if something goes wrong
Install the prerequisites: SL4A including Python4Android
Switch your SuperSU or superuser to grant su by default. You will have to accept lots of commands otherwise, and I had problems with the dialog of my SuperSU doing this
Install my pin_change.py program in the sl4a/scripts directory on your phone, it is attached to this post. Maybe you have to rename the extension to .py (had to rename it due to forum restrictions)
Start pin_change.py through SL4A
It will make a backup of your current password and allow you to set a new numeric pin
Reboot your phone, the lockscreen caches the old settings otherwise
Disable USB debugging and switch your superuser settings back
That's it, you can now use an easy pin on your lockscreen.
Maybe you are missing the sqlite3 command. pin_change.py will check for it and notify you if it is not there. The easiest way to get it is the "Sqlite installer for root" app on the market.
pin_change.py allows to restore the backup or to set a new pin. You should restore the backuped password before you change your encryption password through the Android GUI.
I tested this on a Samsung Galaxy SII and a HTC Sensation, both EU models running a 4.0.3 from the manufacturer. I just rooted them, no custom roms.
The only thing I could find was that the vpn account data is encrypted too and you now can't enter the password anymore. So you have to redo you vpn setup, no big deal.
Just to make it clear: this allows you to use a numeric pin for unlocking where e.g. the Samsung Galaxy S2 requires a alphanumeric password. This tool does not (yet?) allow to use a pattern to unlock.
You do this on your own risk, no warranty, this script may brick your phone, drink all your beer or eat little children. So be careful.

When you use a numeric pin on your lockscreen, someone could use fingerprint locations to guess your pin code. So you should make sure that noone can make enough tries till he finds the correct pin.
Here is how to limit the number of failed pins:
Install Tasker
Install Secure Settings
Open Tasker and Create a new Profile
Context based on state - Plugin - Secure Settings
You can configure it to the desired number of failed login attemts
New Task - Misc - Reboot - Shutdown
I have set the failed login attempts to two. After that the phone instantly switches off. When switching it on again, everything is encrypted and you have to enter the long and complex encryption password. Voila, we are secure!

While I'm at it - one more hint about device encryption:
When I first tried to encrypt my Samsung Galaxy S2, it started and showed a green robot. After about a minute it rebooted and that was it - no encryption.
I activated adb logcat to see what was going on. Lots of other stuff and finally this:
Code:
E/Cryptfs ( 73): unmounting /data failed
E/Cryptfs ( 73): Error enabling encryption after framework is shutdown, no data changed, restarting system
I thought a bit about it and had the idea that maybe the external sdcard is still mounted and that mountpoint creates this problem. I was right - removing the external sd solved it.

I need a little noob help here, using Samsung Galaxy SII on ICS 4.0.3. I don't have much experience with Python, only installed it to make this script work.
Running pin_change.py I get the "sqlite3 command not found" error. Now I guess I have to install the thirdparty.tar.gz from the Python for Android (Google Code) website, but I have no idea what to do with the downloaded file. Could you please help?

Yes, the problem is the missing sqlite. I will do as you told once I re-encrypted my phone. Will keep you posted once I have the results.

It worked! Installing sqlite fixed the problem. Thank you!

Hi robberknight,
Thanks for this very interesting work. Will this work on Honeycomb as well, or just ICS?

I don't have a Honeycomb device to test so I don't know.
You can just try it though. The script tests the password before changing anything. The test will fail if encoding is done different on Honeycomb. And the script also creates a backup before overwriting anything.
I consider the chance that the script breaks anything quite low. But it can very well be that the script aborts with an error because something is done different on Honeycomb.

sqlite3 binary
Some hints:
I failed to install "Sqlite installer for root".
So I grabbed sqlite3 from SuperOneClickv2.3.3-ShortFuse.zip.
Somehow it won't start within the python script. It throws "cannot locate register_android_functions" in def sqliteFound(self) which ends up with the error "sqlite3 command not found". Executing sqlite3 -version in the shell caused no problem.
I managed to get sqlite3 working by installing again from "Sqlite installer for root" after proper remount of /system in read-write mode
"mount -o remount,rw /dev/block/mmcblk0p15 /system"
The PIN-Lock works now!

I'm not in JB, but when I got a "can't read salt" error recently, I got through it by changing SU back to "prompt" and then clicking through the prompts. I have no idea if this might work for you though.

Thank you for sharing this information. This is exactly what I was looking for
I think it is logical to have a complex password for booting your encrypted android, but using a simple pin for unlocking your screen. Who wants to enter their complex password every time the lockscreen pops up?
Im running cyanogenmod 9 on SGS2 and I will report back here if it doesn't work somehow.

The easiest way to accomplish this is to set the password for the boot using vdc cryptfs changepw PASSWORD.

that will change the password for the encrypted volume while keeping you pin whatever you initially set up

can you please elaborte on this? I assume the steps would then be
1) encrypt android phone using normal GUI way from the settings
2) Change PIN to some easy to enter PIN for the lock screen
3) Use vdc cryptfs changepw PASSWORD to set a strong password for the authentication during boot?
Update: Yes, that is how it works. See http://blog.joelj.org/2012/08/02/st...setting-a-different-bootlock-screen-password/

Script method is better than "vdc cryptfs changepw" on Galaxy S2 Epic Touch
This script is the way to go for the Galaxy S2 Epic Touch for at least 2 reasons:
1) Using the "vdc cryptfs changepw" method doesn't seem to work. I tried Cryptfs Password and EncPassChanger both of which fail with the error that the current password is incorrect. My presumption is that the EpicTouch stores the password differently than a Nexus. (I tried to use it command-line as well, but I'm not really versed in that method so I'm not sure I was doing it correctly.)
2) The EpicTouch also requires an alpha-numeric password in order to encrypt. It will not accept a PIN. You must choose a password with at least 6 characters, including one alpha and one numeric. Again, this is different than the Nexus which appears to accept a simpler numeric PIN for encryption.
Thus, using the "vdc cryptfs changepw" method would not be optimal because you'd still be stuck with the alpha-numeric PIN that you used to initially encrypt the device. Thus, this script method that changes the GUI PIN is much better.
A hint for those who are trying this and have never used SLA4/Python (as I was):
1) Load SLA4
2) Menu-View-Interpreters
3) Menu-Add
4) Select Python 2.6.2 - the SLA4 app will go get Python and intall it with the correct linking
5) Exit SLA4, then start Python and select Install, and when finished, exit Python
6) Put the pin_change.py file in the SLA4 "scripts" directory
7) Start SLA4
After that, when SLA4 is run you should see the script in the pick list. Upon selection SLA4 will pop-up an icon select-list. Pick the gear, which will run the script.
Thanks to the original poster for sharing this.

This is awesome! Thanks goes to the OP!
I have one question though, Is there a way I can modify the python script to use the pattern instead of the pin ?

Although this worked great on my Sprint S2, I've just upgraded to the S3, (running JB 4.1.1) and I'm getting stuck at "can't read salt". I did what I could and I looked through the script and confirmed the database is at the same location in the S2 and S3. However, although I can find the salt in the S2 database, it does not appear in the S3 database. Obviously, that's why it's getting the error. Unfortunately, I can't find any information as to where the salt in stored in JB. My thought was to make a small modification to the script and point it to the correct database.
This script made using encryption on the S2 very pleasant. Any assistance you can give in helping to get it working on JB/S3 would be greatly appreciated.
Thanks.

Awesome... but
Hey there!
Awesome little script that just works.
I am running on my Galaxy S3 here, feeling a lot more secure.
However, I just upgrades to Android 4.1.1 (Build JRO03C.I9300XXDLIH) and the script does change the password to a pin, leaving the encrpytion password intact, but it wont switch the device to pin input screen. I rather have the text box field, which is kinda annoying to use.
Would that be easily to fix for you?
Cheers,
and thanks for all the hard work,
much appreciated!

[Q] Unlock problem

earlier today I found out my little sister knew my pattern so I changed it. But when I changing the pattern I didn't pay attention a lot and know I forgot the pattern.My data and WiFi are disabled.I can't sign in to my google account with the phone now.
My question: I can't sign in because data/wifi is off? If yes is there a way to turn on wifi or data without unlocking phone?
I'll be thankful if someone help me because I can't loose my apps and setting
I'm using Galaxy mini CM 7.2 official

Hi, you can go into recovery mode and make a data wipe, but you will loose all apps and configurations.
On CM10.2 is it possible to activate wifi or data from lock screen but i don't kow cm 7, sorry

if you have usb debugging enabled you can break it with adb by using adb shell commands
follow this guide in my blog http://www.blog-android.com/general/break-pattern-lock/ for more details and dont use that aroma method it is only for mediatek devices
you can try the other methods given there

I don't know why you facing this! if I forget my password/pin my phone gives me a option to enter my gmail id and password and then directs me to change the password/pin! this occurs even If I remove my SIM card also!
anyway a probable solution for you - http://forum.xda-developers.com/showthread.php?t=2225695

I am just sharing my experience
I had locked gionee m2 without root and without debugging enabled I was able to disable lock with out wiping data
What I did was
1)flashed carliv touch recovery using special flash tool
Use PC to Flash*recovery.img*using sp-flash tools. (Please be aware of how to install required drivers etc..)
Select original scatter file of your version of ROM. If You are using stock ROM, Make sure that you have not altered the phone partitioning earlier.*
Be careful and Remember to select/tick only 'recovery' in the list. You can also check preloader if you like. and select ONly 'download' button. (NOT firmware upgrade!). Connect your switched off phone to your PC. Wait till your task is complete. Shows you a green circle.
2)backup of data was made using carliv touch recovery (ofcourse with locked phone data)just in case anything goes wrong.
At this moment carliv touch recovery was working but boot and power options were not functioning
3)now flashed rooting file this time by carliv touch recovery
4)carliv touch recovery has aroma file manager too. But I was not able to open lock by this method as
Aroma File Manager, Click on menu option and go to settings*
Select Mount All Partitions*
Now, exit from Aroma File Manager and reflash it.*
Now, you will see each partition is mounted
5. Now, go to /data/system
Note : If you have sd-ext mod to increase internal storage, go to /sd-ext/system/
6. Now, If you have to remove pattern lock, long press and delete gesture.key
If you want to remove password, delete password.key
7. Exit the Aroma File Manager
8. Reboot*
9. Enjoy*
Didn't enjoyed this method somehow I don't know but it didn't worked for me as this folders didn't showed above said files.
5)now I flashed pattern password disable. Zip file using carliv recovery
And on booting phone screen asking for google id and password was gone link http://forum.xda-developers.com/attachment.php?attachmentid=1900741&d=1366570627
This was my method to unlock pattern locked gionee m2 phone but this can help you out too

Caterpillar S60 FRP Unlock / Bypass / Removal?

Hello All, Before you ask no the phone is not stolen. I'm a idiot but not a thief. So I wanted this phone for a while and I saw it at a pawn shop while in Oregon on vacation. So I purchased it sorta cheap with the original box cables books the works in mint condition. The phone did not come with the prior users information so I did a Hard Reset from the Boot menu and now it ask for the prior persons info which I obviously don't have. Called Bullitt who informed me that they can't fix it that it is an android issue and to contact google. Which I can't seem to find information for. So tried a few of the unlock methods for other phones on youtube to no avail. Can't return the phone so unless I somehow fix it I'm out $350 bucks. =/ Any help would be appreciated.
Phone Details:
Android Version 6.0.1
08/05/2016 Security Patch
Baseband 025.01
Kernel Version: 3.10.84-perf-gb111a7d

Re: FRP bypass
Sorry to hear. Not too long ago in the past, you could hit google and bypass FRP in minutes on the first attempt. Now, FRP bypass how-to's have become a great ad pusher, and 95% of the info has been patched.
Save yourself multiple headaches, and put your research into learning how to flash a new rom. That info will be much more reliable, you'll get a much better Android version, and frp will be gone.

Thanks for the reply, I actually did try to see if I could just unlock the boot loader and flash a new Nougat Rom to it since it's almost a vanilla version of Android OS but couldn't really find anything along the lines of posts that might break down how to go about unlocking the boot loader. =/

There was a guy here who showed how to overwrite GAM as a user app using DirtyCow. I can confirm it is possible to get a root shell with DirtyCow and replace files in memory on the S60. His FRP bypass looked like it would work for you. Look on youtube, it's about a 15 minute long video.
The version of DirtyCow that worked on my S60, partially, was found here in D1kiy's "Universal Debloater" package. I don't have a Windows machine so I just used those files manually through ADB to replace run-as. There's nothing made specifically for this phone, so you'll have to use your brain and cobble these methods together. Basically, where he goes into the shell and uses the cat command, I would try to create that file and use the "dirtycow64 <file> <location>". You could TRY to install D1kiy's run-as and use "run-as exec cat <file> >> <location>", but I don't know if that will work or not. It didn't work to disable packages on my phone, and it's more steps.
What I'm trying to do is replace my hosts file with a larger one, which of course can't be done directly with DirtyCow. If you get any farther towards real root than removing FRP, please let me know. Good luck!

I posted a wetransfer link for the files should be good for a month if you need them or if the link is taken down PM me. Most of the ideas for this FRP Bypass came from Ghostlyhaks.com I just complied what worked and what didn’t to get FRP Removed. Thanks to @aff3p for giving me a push in the right direction. Also thanks to XDAdevelopers whom I have constantly learned a few tricks from.
Once it is FRP unlocked it will download updates so if you don't want them make sure to block them upon factory reset.

help with FRP removal
Hello Sirs,
I have just bought a CAT S60 from my carrier as a used handset, and I've ran into this FRP problem too. I could take it back, since I have a 2 weeks guarantee for this, and they would pay me back its price, but since it was a good price, I'd rather keep it.
I've tried the solution above, I've managed to get to the google app, and searched for ES file manager, but when I click on the app, the phone tries to open google play which directs me back to the point where I should enter the previous user's data.
As far as I can tell, my ROM version is after 01. June, 2017. Or at least, I've entered android recovery, and the latest recovery log sais: ro.bootimage.build.date= Thu Jun 1 12:12:51 CST 2017.
Do you have any suggestions?
Thanks in advance
P

Solved

Do you have TWRP or stock recovery?
Assuming you have TWRP go into the file manager found in advanced and go to /data/system and delete the locksettings.db or gesture.key
Hope I helped

Samsung Galaxy S7 - FRP Lock

I have a canadian S7 (8.0.0/R16NW/G930W8VLS5CSA1)
It's a company owned device that we are trying to re-purpose from a terminated employee. The device has been wiped but we appear to be stuck verifying account. I've gone over a number of threads but i can't seem to find a concise set of instructions.
Any help would be appreciated.

Can't you sign in with the email and password of the Google account of the terminated employee?

OK well for future reference always,....ALWAYS remove the google account from the phone before doing any kind of factory reset when you don't know the credentials.
Method 1 take it to a Samsung service shop with proof of purchase / ownership and they will reset the device for you, (might want to do this before messing around with it).
Method 2 is to get TWRP onto the phone to wipe "user data" then reboot , once you get TWRP on your home and dry. Can flash with Odin and depending on how up to date the device firmware is will depend if it will work or not.
Method 3 is to use the use the OTG cable (which came with the phone) to plug in a USB drive with all manner of frp disabling .apk's on. Lots of guides on line for this.
Method 4. I know some of the videos on youtube look confusing but depending on how old your device firmware is some of them still work. Any guides from late 2018 onwards should be tried, don't bother with any guides older than September 2018
Method 5. Is the nuclear option of "nand erase all" in Odin only use this if you are desperate as it's likely to corrupt the efs partition
It's very difficult to give specific advice without knowing the exact state of the phone, firmware update, security patch etc.
FRP lock is an absolute bast**d to resolve. I hope this helps.
Update
Apparently this method works on an S7

How are you suppose to get into the device and remove the google account when you don't have the device password? Most if not all of those options require USB debugging be enabled no? Which i can't / wasn't able to do without pwd. We don't have samsung service shops around here.
Is there no way to load from usb drive

None of the methods i've listed require you to have password access to the device. I'm assuming from what you've written in your first post, you can turn the device on but are stuck at the Google verification screen? AKA, FRP lock
No you do not necessarily need USB debugging turned on
The OTG cable IS connected to a USB drive if you use that method
I mean this in the nicest possible way but do you have a basic understanding of the steps required to modify this phone?

i don't believe any of those methods work on s7 on android 8. No file manager pop, no google assist on keyboard, sidesync doesn't pop either. I believe the latest that tutorial works on reliably is 6.1 i may be wrong however.

Thanks for response,
When i holde volume up and down it doesn't do anything from start screen. On my device voice assistance is turned on by holding 2 fingers on the screen until it beeps. Then a tutorial comes up. swiping L shape does nothing.

Simple go to ebay search for samsung galaxy Google lock removal service and have one of them remove it for you. I have done this many times and it dose not cost that much.
