Hello folks,
idk if anyone of you guys had a hard time with the same annoying 'feature' on ics roms which forces you to set a PIN/password/pattern lock when you try to install enterprise certificates into your credential storage.
As for myself I need some of these certs to log into the WLAN at my university (which is 802.1x protected). But I don't feel the need of locking my phone.
So I exploited this to go around setting a password for the secure lock screen.
-------------------------------------------------------------------------------
Prerequisites are a rooted phone, a root file browser or adb tools and apparently your certificates.
I tested this on AOKP build 38 and 39 on a rooted HTC Sensation XE and will check this on two other devices the upcoming week.
UPDATE: seems to work even easier, I made the changes inline since the previous workaround did not work in every case.
Step 1:
Download the certificates to your SD card and/or install directly via browser/email etc. Do as you are asked and set up a PIN/password/pattern lock. Remember it
Step 2:
now with your root file browser go to /data/misc/ and recursively copy the folders keychain and keystore to a save place.
These are the folders containing the certificate files.
(See [System settings > security > Trusted credentials] for installed certificates)
With adb tools you can for example do this:
Code:
adb shell
su
cp -R /data/misc/keychain /sdcard/certificates/
cp -R /data/misc/keystore /sdcard/certificates/
Step 3:
Go to [System settings > security] and click [Clear credentials] at the bottom of the menu. Now your previously installed certs are wiped and you are free to set the lock method to [none], [slide] or [face lock] again.
Step 4:
Finally fire up your root file browser again, set /system as read/write and copy the in Step 2 backed up directories back to /data/misc/. They are now installed as the before but since CertInstaller.apk does not get involved, noone forces you to lock your phone.
in adb shell:
Code:
cp -R /sdcard/certificates/* /data/misc/
Now you should be able to find your newly added certificates in the System list under [System Settings > Security > Trusted credentials] in the [User] tab and thus be able to log into your desired WLAN.
I hope this helps some people out there. When I get deeper into developing maybe I will find a 'cleaner' method for this.
have a good night,
.eXa
Thank you for sharing! I have been really looking for this kind of hack.
Sadly I can't use it as my certificate has a different structure: it seems to install 3 files in /data/misc/keystore/
The files are 1000_USRCERT_Polimi ; 1000_USRCERT_Polimi and .masterkey
I tried copying these files to the new directory and even changing the file extension but it did not work.
I don't know if this issue is rom or certificate related.. anyway I am using a stock rom on samsung galaxy s3.. perhaps samsung manages differently certificates..
Have you any clue on this? Thank you!
hey, thanks for the reply.
alright, I figured something new, maybe try the updated version of the tutorial and pls tell me if that works for you.
greetings

You were fast! and I think you made it: I can now select the certificate in the wifi options dialog (so it's correctly installed).. but I can't test the access to the network until monday.. Anyway I am convinced that it made the trick and it was really simple, I must say.
Thank you so much , this will be useful to many people!
Your trick helped me only partially. It allowed me to install the certificates just fine. But as soon as I try to connect to any 802.1x protected Wi-Fi network, the phone bugs me again with setting the screen lock. So I need a workaround for accessing the key storage.
I tried it and sadly it does not work: it asks me a password to activate the credential storage.. only problem is that I never set a password for it so I can't insert it and use the certificate. Too bad but I think it depends on the certificate.. anyway thank you very much for the help provided!
so, back from vacation.
@grgur: in your setup it is the 802.1x wlan that forces you by corporate policy to lock your phone. i am still trying to figure this out, i will try and search the system where stored wlan access points are stored. update will come as i find a solution to this.
@grievous: which version of android are you on? try clearing your credential storage first, then set up the password and then add the certificates. after that proceed with my tutorial.
since i am in the middle of learning for my exams i have really no time to go on with my android studies... it seems like in the long haul someone has to "fix" the app that handles phone lock and device policies. i know who the bad boy is but i am lacking time right now, so hopefully i get this done by the end of august.
i'll keep you up to date with my progress.
greetings
Is there a one-click fix for this yet? Bloody annoying...
Working great on stock rooted JellyBean nexus 7. Muchos grazis!
As soon as i go back to university (politecnico di milano) i will use your suggestion! Has anyone already tried with polimi wifi network?

I was using a samsung stock rom 4.0.4 and the tutorial worked but when trying to connect again it asked me for a credential pwd (that I never set). Now I'm on CM10 so there should be no problem. As soon as I get to Polimi I'll try
doesn't work for me (SGS2 AOKP JB)
Hi!
I've tried to apply this solution to my device (SGS2 AOKP JB), but after clearing the credentials and copying back the keystores/keychains the user credentials cannot be found (Trusted credentials > User is empty).
Could anyone please help me with this one?
Thank you in advance.

In fact i was really searching for this i will try this tomorrow !
Sadly exchange with client certificate refuses to work after trying this hack It says that it can't found the cert it needs..
I have found the permanent solution !!!
I hope this will solve everyone's problem here.
These are the steps I have done after installing Eduroam certificates from my university:
1. Obviously I have installed CA
2. I had to choose which lock screen style will I use (I only could have choose between pattern, PIN, and password), it doesn't matter which lock screen style you choose between those three.(FYI I have chosen pattern)
3. After that I have failed to swipe my lock pattern correctly 15 times
4. The "Unlock with your Google account / unlock with your PIN/password" screen appeared.
5. Choose the "Unlock with your Google account" and type in your username and password
6. After that the "Choose your lock style" screen appears. DO NOT CHOOSE ANY OF THEM, since swipe still can't be chosen
7. Just press back to exit this menu.
8. Lock your screen and unlock it ---> You have swipe unlock enabled along with the CA certificates !!!

Same thing here. Although files are backup up, there is no certificate showing up on the list. It would be great if someone found a solution, this lock is driving me nuts.
Hi, this seems almost too easy, and it's more of a workaround than a solution, but it works:
Try to login to your network
Accept the request to set up the mandatory screen lock and set one up (any kind)
Connect to your network
Go into Android settings/Security and change the screen lock type to None
Your network credentials are now saved and there is no longer a screen lock.

The last time I tried this with my CyanogenMod install, removing a pattern/password/pin was not possible because of the certificates. Only after removing the certificates, the screen-lock-type could be changed to a non-pattern/pin/password type.
Hi,
As you may know, you cannot enter the secret codes (e.g. *#0011#, *#27663368378#...) on a device that has not been enabled the HiddenMenu.
I need someone to help me to test if these codes work on your device by using my app: Shortcut Master.
Here is how:
- Install Shortcut Master app: https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite
- Go to menu 'Secret Code Explorer', select your desire code (e.g. 0011, 27663368378, 0228, etc...) and tap to launch it.
- You can select 'Launch 0' or 'Launch 1' to test if it work. 'Launch 0' requires ROOT access.
Please kindly test and feedback. Thanks.
Hrm I just changed /efs/carrier/HiddenMenu with a root browser and changed it from OFF to ON and reboot, all codes work just fine.

Yes, I see. I have also faced with the same problem as you
I can't remember but there is a code that clear the APN settings. To fix it, you have to add the APN manually:
open Settings --> More networks --> Mobile networks --> Access Point Names --> + to add
If you don't know what parameters to input, you may have to contact your service provider (your mobile operator) for help.

This is a tested and working Exchange Security Bypass that I am using on my AT&T LG G3. This mod should work on any variant of LG G3 that is running stock or AOSP ROM's.
All credit goes to the below developer, I was simply looking for a solution to bypass the exchange security policy that required me to have a password or pin on my lockscreen. After several tests using Xposed Framework and other APK's I came across this and it works flawlessly. You can see the developers thread here.
http://forum.xda-developers.com/showthread.php?t=1965468
DISCLAIMER: I'm not responsible if:
• You get caught by your employer and are punished in any way
• This bricks, breaks, scratches, dents, misplaces or cracks your phone
• This security bypass leads to any negative outcome.
USE THIS AT YOUR OWN RISK.
I have rooted my phone and used Root Browser to perform the following steps (You can use ADB as well, please follow the guide in the link above).
Instructions:
1. MAKE A BACKUP OF YOUR STOCK EMAIL (LGEmail.apk & LGEmail.odex) - Copy and place it in another folder incase anything happens and you want to revert.
*Stock LG Email is located in system/priv-app2. After your make a backup, delete the stock LGEmail.apk and LGEmail.odex files
3. Download the files attached to this post and put them in the system/app folder
4. Change the permissions of the two new APK's (Exchange2.apk & Email.apk) to rw-r-r (DON'T FORGET TO DO THIS)
4. Once the 2 files (Exchange2.apk & Email.apk) are placed in your system/app folder, click on them and install
5. That's it...close out of your root explorer, open your new email app and set up your exchange account. :good:
I hope this helps users who are looking for a solution to their exchange security issues like I was. Enjoy
btw u can only do this if u are rooted..for those who arent dont even try it

It should not be necessary to delete the LGE apps, the two can work side by side. And if you are set on disabling the LGE app it is probably better to freeze it with TBU than delete, in case you change your mind later.
Those contemplating the use of this mod should keep in mind that the LGE stock email app is FAR, FAR, FAR more intelligent than the stock KK email app when it comes to autoconfiguring your Exchange connection. In fact I recommend running the LGE stock app first, then going into settings and taking a screenshot to document how the account was configured. You will almost certainly have to enter this information manually into the KK app because it will be unable to figure it out on its own.

Go to data/system and there is a file locksettings.db. Open it in SQL editor. Next tap on locksettings, and u should have a item listed as lockscreen.password_type . Change the value for this to 0. That will change lockscreen to swipe to unlock.....

I'm assuming I'd need to set up exchange first and once it enforces the password lock I'd need to modify the file? I would assume when adding an exchange account it would change change that value.

Run TBU, touck checkmark icon in upper right of screen, wait for "Calculating scenarios" message to complete, scroll down to Freeze/Defrost, touch appropriate option (could the color scheme of TBU be any more awful than it is? sheesh, the developer must be color blind ) then select apps to freeze/defrost.

One odd thing is happening. I have root explorer installed and from that application, I browse to the location where the locksettings.db file lives. However, when I click on the file and the "Complete Action Using" pop up window comes up, I don't see SQL Editor as one of the choices there. Alternatively, I thought I'd just open SQL Editor directly and try to edit the file in there; this does not work since SQL Editor has not been granted root access.
Anyone know if there's a way to grant a specific application root access?

Got my oneplus today. It has not taken me long to get it rooted with TWRP. Many thanks to Chromium for his step by step process here http://forum.xda-developers.com/showthread.php?t=2788632.
I am a Tasker user and an app that I use is Secure Settings. When I go to enable the System+ Module, it tells me that Root Access Disabled. Root access is currently disabled for all applications by a system setting. This setting will prevent Secure Settings from performing several functions. Would you like to enable it now? When I select "yes" it takes me to my developer options page. I cannot figure out what to select to enable what it wants. I have used this app on my S3 and my LG G2 and have never had this come up. I am stuck!
I am running stock CM11s.
I am confirmed to have root access with Supersu. I am running xposed modules.
Under debugging check the root access setting is set to apps and adb.

I had the same problem as the OP. I did the setprop persist.sys.root_access 3. This allowed me to turn on System+ in Secure Settings. However, now Tasker force closes every time I run it. It will run, but as soon as I switch away or run a task it will stop. How do I undo this change short of reinstalling my rom?

Okay, so I found somewhere that the default setting for persist.sys.root_access is 1 so I set it back to 1. Still no luck. But I did get it fixed.
First, I backed up tasker, then I uninstalled Tasker and Secure Settings, Reinstalled tasker, restored my backup then installed secure settings. It let me endable System+ Right away and all seems to be working. WHEW. I was getting frustrated to the point of considering selling the phone cause tasker didn't work.

As we have all seen with this latest STOCK G935U [BQD2] Firmware for T-Mobile indeed it runs smooth and personally I have experienced better performance without all those carrier-bloat applications by default. Dating a week ago, I tried to root this build version and for some reason I experienced infinite bootloops after my device boots up. So I did some research as to what system apps could be causing this I still I can't believe that a network-related system application was causing this issue.
I am talking about com.samsung.sprint.chameleon as mentioned by @qwewqa here -> https://forum.xda-developers.com/tmobile-s7-edge/how-to/4-28-t-mobile-935-firmware-t3597866/page10
I will not go in-depth about what this is but this relates to a network configuration. I will post a reference on this if you guys feel like checking out...

------------ HERE COMES THE MOST IMPORTANT STEP ON THIS GUIDE ----------
2 - Install Package Disabler Pro from OSPolice. Play Store link ...
https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=es
3 - Open the application, activate Device Administrator, just hit next or ok or just follow through the setup and once the apps list loads up look for the system app with the name of: com.samsung.sprint.chameleon. Go ahead clear data and DISABLE it. After you are done disabling this system app, you are now safe and good to follow through the root method below.
4 - I suggest that you use the root.bat file provided by @Quickvic30 on this thread to root your device
https://forum.xda-developers.com/tmobile-s7-edge/how-to/heres-how-rooted-nougat-s7-edge-g935t-t3567502
IF YOU HAVE SUCCESSFULLY BOOTED UP YOUR DEVICE PAST THE SAMSUNG SCREEN WITHOUT ENDING UP IN BOOTLOOPS (Bootloops may occur within 30 seconds after booting up from the Samsung Screen) THATS IT, YOU ARE DONE!

Since I don't see any mention of using the engineering kernel should I assume this method does not work for US models?
So basically you take qwewqa's discovery, make no mention of him, then pass it off as your own. Then copy and paste some steps from other people, and submit it as your work?

As referred in the procedure section. The main and original root method goes to the forum thread linked above. As I briefly specified in the background info section, this is just a quick fix in performance and stability when applying root to this build.

I didn't copy nor plagiarize any information from their respective owners. Credits are given, very briefly detailed information on the steps as to the main reason of this thread is just giving the list and proceed with the order of steps to successfully achieve root. The link that I attached in regards to the conflicting system app that where I noticed the issue with other models.
I didn't look into @qwewqa thread comment regarding this, and I apologize and edited to credit him on this finding.
The debloat list provided is extremely aggresive. It removes the stock gallery, stock calender, lock screen wallpaper, stock contacts, Bluetooth, and all google back up services.
Your list is great for the hardcore folks BUT you have to go back through the lost and re-enable the apps and clear the data then re disable them.

Brian,
Thanks for bringing it all together. I am currently rooted on T-Mobile QC1. I wanted to go to the U firmware wanted a tested way to root first.
Pat
Thank you kindly. Going to try this out right now
gonna give this a try, Any kernel tweak recommendations? how smooth/fast is it or does it lag like a bunch
any fix for the finger print sensor?
Im think the eng is conflicting with a app killing the fingerprint sensor

Hey Pat,
In fact there is a way to root the U Firmware and achieve functionality and administration. All thanks to their devs for their work

As a matter of fact, the root.bat from @Quickvic30 does all the jobs needed. I strongly suggest running his method. No L Speed, no Kernel Adiutor. Just Titanium Backup to freeze/uninstall bloatware.

Hmmm...to be honest I didn't have any issues regarding the fingerprint sensor. Have you solved your issue by now?

Yes, I also have the same problem. The fingerprint sensor has stopped working after flashing the Eng Bootloader.

I tried to use this method but my phone won't let me change permissions. It pops up with a message that says "changing permissions was not successful. Please note that some file systems do not allow permission changes." Is there something special I need to do to enable permission changes?
Also I am using root browser to do this.

Try another file browser. Root Explorer is what I have always used.

Awesome man it worked! Thanks a lot. Root explorer seems pretty legit by the way. I've only ever used root browser.

Glad it worked. I have been using Root Explorer for as long as I have been using & rooting android phones.

I also had that problem too. Just extract the libs and overwrite them in /system/lib and /lib64, then change the permissions to rw-r--r--. Apparently, it only worked after overwriting the files.
