So it hit me the other day when i was copying files onto my phone with qtadb(stuck with mtp in cm9) that even if a pin on password is set on the phone i can copy/erase anything from the phone, worse if its rooted, if its connected to a computer. Doesn't this kind of defeat the purpose of the pin/password?
If it even possible to disable just the data +/- pins if the phone is locked with a pin/password, and re-enable them once its unlocked?

That's possibly do-able.
If you edited the sources you could probably disable adb on lockscreen... But if you close all the holes, and something goes wrong, you are stuffed
Remember recovery is always the best way "in" to the device It has root access anyway, and it's unprotected.
i am not an expert or anything.. but to my understanding.. if u dont enable usb debugging and u have lock screen.. u CANT directly modify the data in phone without opening the lock screen first.. i just tested it now.. even if i try to go to usb mass storage mode, im required to open the lock screen and press connect mass storage...
unless u go into download mode and adb but that also require usb debugging to be enable

Ya i guess if someone knowledgeable enough wants to get into your phone they'll just use recovery. Is protecting recovery possible?

Quite right, disabling usb debugging won't allow you to adb into the phone. Tasker allows you to run commands if the display is off and unlocked, anyone know the command to enable/disable usb debugging?
i dont know about the tasker's command.. but if u have lock screen and disabled usb debugging.. it should be quite safe so its not useless
There is a reason you get this shiney warning dialog when enabling USB-Debugging.
Ever bothered to actually read it?

Encrypt the phone?
Think encrypted phone cannot be accessed through recovery
KeePassDroid.....
Best way is to use 3rd party applicayions - KeePassDroid is free and very good, you can set very secure passwords and it has a desktop application too
I use it to store usernames/pwds and by all accounts its pretty secure, it also supports different encryption types on the database
Security
If your phone is stolen better to use some app from market that you can control remotelly and ERASE COMPLETELY the phone...
Meanwhile, encryption could be enough.
And both together maybe is the best.
I noticed flashing roms (checkrom) that i would still have a lock screen but any way i connected the dots it would unlock.

This is correct.
Using encryption with a proper password (not PIN/Pattern) you need to enter the password in recovery as well.
So even with adb root access in recovery, it's impossible to access the data without the password.

That's because the flag in EFS for the pattern lock is still set, but no actual pattern is set in the system's data.
So, imstead of never letting you "in" anymore due to no correct pattern it just always unlocks.
I forgot the pattern of my lockscreen, tried too many times and cannot unlock with google account.
Unfortunately wifi, data and developer mode is turned off.
Was able to locate and extract gesture.key but how can I remove it from data.ext4?
SD-ROM is containing all my phone numbers, messeges etc.
Please help, thank you in advance.

How have you found and extracted gesture.key?
To remove something from data.ext4 you could mount the file in Ubuntu/Linux which will grant you access to the files.
Code:
[CENTER]sudo mount -o loop data.ext4 ~/Desktop/data
then edit it and unmount it
umount data.ext4[/CENTER]

Had a quick look and if you aren't given the option to reset it, after ~5 failed attempts you could try downloading lock screen bypass from the market to see if that works, I'll attach a copy of the apk if you cant get it.
Just tried it and its 5 failed attempts for me, then the offer to reset.
unfortunately this did not work for me. think it is locked at a different point.
I will give the sql method a try: http://forum.xda-developers.com/showthread.php?t=485988

I'm glad that you could solve it and unlock your phone, but I am curious, why it didn't let you unlock using Gmail without data.
Sometimes, I unlock the phone using gmail and pass EVEN with airplane mode on and no WiFi. Isn't it supposed to check with your already registered gmail account? thus no need for an internet connection?
Anywa, enjoy your phone.

Glad you got round it, I didn't mention anything adb wise as I though you said debugging was turned of, at least you've learned something. And being able to edit the data.ext4 on a desktop has it's benefits.

Yes Marvlesz, was also strange to me. Tried the same with my ICS Pad without any connection while I read somewhere that even wifi should not work only when the device is connected to USB!? Maybe it depends on the version? My phone was on ICS 4.0.3 (IceCreamTosti_v0.10_AOKP_M4) with Tyatung Kernel 2.6.32.
Now after all my installation got broke but I can access my stuff, finally save it and reinstall newer version while I have a good reason now to do that

Yes HypoTurtle, debugging was off and I did´nt use adb. With your kind help I mounted data.ext4 and changed settings.db in linux.
My friend has Samsung GT-S6102, and in trying to change the pattern lock, he did something wrong, and now is locked out.
The next step is to enter his Google account login and password, which will let him log on and create a new pattern lock. The problem is, the phone has Wi-Fi and Data turned off.
I think he is now dead in the water, with no options left but to factory-reset the phone.
Is there any way to get the phone to connect to Google, even with Data and Wi-Fi not connected? If we could get 'data' or 'wi-fi' on, we would be all set - but unless there is some diagnostic way to do this from a connected PC, I can't see much else we can do.

Try rooting the device & flash cwm. Then use aroma filemanager to go to the path, '/data/system' delete the file gesture.key
Hit thanks rather than typing it now Free

How about if I both hit "thanks" (already done!), and also say thanks!!
I've been here to xda-developers before, and now have my own device to use to learn rooting and installing custom ROMs. Haven't done it yet. I suppose this might be a good time to learn, but if I mess up, my friend isn't going to be very happy with me.
Let me ask you two questions - if the device is "locked", how can I even root the device? Doesn't it have to be on, running, and ready for whatever it is I need to do? A second question might be how I find the information here to learn how to 'root' a GT-S6102, but I can try that in the morning, when I'm a bit more awake (am now in India, and it's 1am).
I was thinking there might be some kind of diagnostic code that could be sent to the phone from a PC, even though the USB connection is probably not on right now, to "wake up" the data or wi-fi, which would enable the normal process of connecting to Google to continue.
I think you're suggesting I root the phone and flash a new OS. If there is a way to do that, isn't there a way to just turn on data or wi-fi?
I found this from a list of codes:
#*3282# Activate/Deactivate Data
Now, if I could only find a way to get that command to the locked phone....
If I do some of the steps you suggested, can I get to a step where I can give the phone those instructions?
here's the full list:
http://www.netlife.co.za/tech-guide...hones/113-samsung-secret-codes-and-hacks.html
1 - questions belong in question & answers section NOT development section
2 - answer has already been given plus iv posted it loads of times so please use search facility
Download aroma file manager & place on route of sd card (take sd card out & put in pc card slot or card reader)
go into CWM (flash temporary cwm zip if kernel doesn't have cwm)
mount system
flash aroma file manager
goto data/system
delete gesture.key
delete password.key
Restart
Thanks to all of you!
Sorry for the thread being in the wrong place....
I just came back here to say I found what might be the answer, which in fact originally came from xda-developers.com Here's the link, but since it points back to here, I probably don't even need to post it:
http://androidlegend.com/how-to-crack-unlock-pattern-lock-of-any-android-device/
Anyway, thanks to all of you for your help. Without this thread, I'd never have known where to look for an answer.
Any further questions I will post in the appropriate place.
Go In Recovery Mode And Wipe Data and Wipe Cache Partition ..........
Thanks to everyone for all the help. It's no longer an issue. They took the phone to a shop and had it reset to new, so it's in effect a brand new phone again. I guess it will at least be faster now.
I find it hard to believe that Google did things this way - it's good for security, but if someone's phone has data and wi-fi off, and a kid plays around with it and it gets locked, they've in effect, killed it.
I guess it's time for me to stop reading, and start doing. That's the only way I'm going to learn this stuff. Again, thanks!

did u reset d phone?? if no here is a work around .
1) insert a sim card that has incoming call facility (u must know the sim card no)
2) make a call and receive it
3) don't hang up.. after receiving when u r in call window it will let u access d notification dropdown window.. now u can activate wifi or data network mode as u wish..
so no need to reset!!

yes it will wipe all user data - this includes installed apps (not system apps) contacts sms and so on
if you want to remove the lock screen password you can do it without wiping data

So when i do this process does my active SIM have to be in the device as well?

it will remove the lock screen - if the lock screen does appear just enter anything you like
your sim card does not have to be in to do this although if your phone is set to not allow access without a sim card in you will need to edit your build.prop to allow phone use without sim

This is working. Easy oem unlock on samsung
When the binary is blocked by the FRP you must install the factory firmware, then enter the recovery and do a factory reset since the FRP prevents external access to the system and data as prevention
You will be prompted for the email and password of the previously used account
When activating the oem unlock you can install Twrp, kernel or custom rom without the activation of FRP security that is activated when you establish a security pattern in the device

I found a way to remove FRP on Samsung J5(6) SM-J510FN model, Android 6.0.1 without flashing the phone, or using Odin, RealTerm or other SW tools, it might work on other samsung devices running Marshmallow 6.0.1 too.
As a new user, I am not able to enter any URLs for the files. do a search for the following APKs instead: Android 6GAM.apk and FRP_REMOVE.apk
Download the above APKs on your comuter, copy them to microSD and insert it in the phone.
Turn on the phone, connect to wi-fi, once you get to the screen when you need to enter your email, press on "mike" icon and choose Settings>>Text Shortcuts>>Add>> and type random text, select it all, then long tap and choose "Assist".
Tap on "No, Thanks" and Type "Galaxy Apps". Galaxy App will come up, tap on it and sign in when launched.
Install ES File Explorer, when launched, go to "sdcard" dropdown>>select the microSD card with the apk files. Install Android 6GAM.apk first, once complete, tap on "Done", install FRP_REMOVE.apk, once done, tap on "Open". This will launch Google Account Manager.
If you are not familiar what to do here, then do the following:
- Look for “Type Email and Password”>>Tap to launch it>>Tap on Try
- Tap on the three dots and choose “Browser sign-in”>>OK
- Sign in with your google account details and wait until you get back to “Google Account Manager”
- Tap on the back button until you get back to the phone setup wizard, you can go as back as to wi-fi settings.
- You can now follow the setup wizard, it will tell you that a new account has been created.
- Once you can access settings on the phone, you can do another factory reset, this tyme without FRP.
Hope this helps
Good luck!

You should probably use a password with letters, numbers, and symbols to lock your tablet. This will also prevent people from connecting it to a PC to transfer files unless they unlock the tablet first.
