[TUT][ICS] bypass Credential Storage phone lock / install certificates

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 !!!

It won't work for me. After 10 failures it says that I have to wait 30 seconds for another try. I have Samsung Galaxy SII with Omega v21 (based on Samsung-stock Android 4.2.1).

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.

How to shut off/disable wifi offloading W/O root

After searching numerous times this forum seems to be lacking this little tip...seems all the threads about it on here say you simply must have root. Not true. As found here: http://forums.androidcentral.com/verizon-galaxy-s-iii/193660-available-wifi-alert.html
open the dialer and enter the following code:

Yes but you have to be rooted and have a custom recovery installed to flash the zip that removes it. You can find the zip in the theme and app section.

LG AS730 (L7 Variant) Rooting / Unbricking / More

LG Optimus Select (LGAS730)
I figured since there really isn't any information on my device, I'd write up some useful information for anyone who has Revol/Alltel and wants to trick out thier phone with root goodness.
I wrote this up at 3 in the morning, so if there's any typo's I'll get to them in the morning
Before anyone roots their device, be aware that our phone has a locked bootloader + System App Checking,
which means if you remove certain system apps, you will be greeted with a "Security Error" message on system start,
resulting in a shiny new brick.
So, as of now, I don't recommend deleting any apps until:
A) We figure out how to unlock our phone and disable the checks or
B) There is a list of safe apps to remove.​
Rooting your LG Optimus Select:
I was previously using the universal ICS/JB root method found here http://forum.xda-developers.com/showthread.php?t=1886460
But it seems that an update might of broke the exploit.
I hate promoting this program because it uses stolen code/it's garbage but it works. (Unlockroot Pro Free)
Just download > Install > Uncheck the boxes to all the toolbar spam > Run > Root > Say no to the powersave crap
I would instead promote SuperOneClick which should work aswell, but it kept freezing for some reason.
Key Combinations:
Power + Vol up + Home = Recovery
Power + Vol Down + Home = Factory Reset
Vol Down + Up / Then plug in USB = Emergency Mode
Downloading the .cab for your LG phone:
1. Find your LG phone model and serial number. [You will have to take out the battery to find the serial number/]
2. TYPE in the following URL or COPY AND PASTE (do not click on link it will not work) it in the URL Line: http://csmg.lgmobile.com:9002/svc/po...eck.jsp?model=[model]&esn=[serial_number]
Now replace the [MODEL] and the [SERIAL NUMBER] with your phones model and serial number.
3. Hit enter to load the page. Now the page should be blank less a string. In order to view the information you have to view the page source code:
a) On Firefox: Tools --->Web Developer --->Page Source (Cntrl + U or Cmd + U)
b) On Safari: Right click blank area anywhere on the page, select View Source in the menu.
c) On Internet Explorer: View --->Source
d) On Chrome: Click Customize and Control at the right of URL Line --->Tools --->View Source
4. Find the number inside <ESN></ESN> line.
5. Type in the following address in the URL Line: http://csmg.lgmobile.com:9002/csmg/b...heck2.jsp?esn=[esn_number]
6. Replace the [esn_number] with the number you got from the first source code.
7. Load the page which should be blank again and just view source code using the above mentioned method.
8. You will then see all of the information about your particular phone including your firmware update link which would lay between <SW_URL></SW_URL>.
9. Copy the URL into your URL Line and hit enter. The download should start automatically.

This program can also be downloaded that does pretty much everything for you: http://forum.xda-developers.com/showpost.php?p=13682353&postcount=1
Recovering From A Bricked Device / Security Lock:
1) Download the LG Support Tool http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
2) Once installed, open it, and click Install USB Drivers > Other Carriers > LGAS730 > Double Click and install
3) Install KDZ_FW_UPD http://www.2shared.com/file/s1ZPxEPL/KDZ_FW_UPD_EN.html (Make sure to install msxml.msi first)
4) Download the the most current .cab for your phone (Method can be found above)
5) Rename .cabs to .kdz
6) Run KDZ as an Administrator > Click the little folder > browse for the .kdz you just renamed
7) Put your phone in Emergency Mode (Vol Down + Up / Then plug in USB = Emergency Mode)
8) Click Launch Software Update
9) You're phone should be working now!

Rooting does work. I also have installed Google Now but for some reason the logcat says 400 Bad Request when attempting to login, so you get the Offline Voice Recognition, Online Voice Recognition, Google Search, but no Cards for some reason.
On another note: It does seem that it only checks that the files still exist, I replaced a number of files in /lib with their Google Now versions and it hasn't made any complaints, the same goes for replacing GoogleTTS.apk (which doesn't work for some reason, we don't get the Google Now TTS, but that doesn't matter as much)
Overall, I'd have to say that I believe the bootloader doesn't check the CRC32 checksum, rather it simply checks that the files still exist.
EDIT: I redact my previous statement about Google Now not working right, it does :3 Just needed to remove and re-add my Google account.
UPDATE:
Another trick is to enable USB Mass Storage Mode:
To do so, Install DriveDroid from the Market. (You can either use disk images to separate your data from the SD Card or use the trick below)
Enable USB Mass Storage as directed by the application (within it's settings)
Plug and Unplug your phone with DriveDroid closed (Do NOT press any of the connectivity options when they appear, they should all be unchecked)
If all goes well, the USB Mass Storage Mode application built into Android will startup and your Phone will mount on your PC. (It doesn't seem to happen 100% of the time, so just toy around, it does work.)
UPDATE 2/6/13:
Firmware Update AS73012a has been released? Anyone install it yet?

So I just got this phone (I'm moving over from a Samsung Fascinate), And so far I'm loving it. It's was smoother the GPS is way more Accurate ! But I do have one qustion. What System Apps are safe to remove ?

That's great, I just noticed in the Optimus L7 thread that their boot loader has been unlocked, was wondering if someone could test this patch with our device as its an L7 variant. According to the threads, its possible to enter emergency mode if a soft brick happens. If anyone's courageous enough to try, please report back. I'd try but I can't afford to replace my phone if something happens to the point that I can't access emergency mode.
Edit: its worth noting that if it does work, we could use the online CWM builder to build a recovery for our device then work on a custom ROM.

Sorry for the no responses, I hadn't been able to do anything else with the phone after we got root working. Unfortunately now I no longer have the device and now have the VZW LG G2.

I also have recently moved to another service provider and a new phone.
But I still have it laying around somewhere, I might mess around with it, maybe try to get CWM working.
Also, I've gotten quite a few PM's after my long absence from XDA for the .cab
I'm assuming since a new firmware release, they've probably taken down the old link.
There was a program I had found which generated the URL based on any LG phone serial, I'll try to find it and post the application which would be 10x more beneficial along with a current .cab.

Hey, I realize this thread is over three years old now, but are you still able to help? I followed all of the instructions to get the phone back to stock, but it can't extract the kdz file. I used UpTestEX_mod2_marwin.exe to convert the cab to kdz, and KDZ_FW_UPD.exe is telling me "Extract file error." Any idea why or how to fix it? Thanks!

Secret Code / Hidden Menu tester needed

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.
