I'm sure i'm not the only one that has noticed that you can't update terminal emulator with modded firmware, i did a mild look through the searches, and didn't find what i was looking for, is there a means to update this, i've tried takeing it out of white list and then updating, but no go... Not that its a big deal TE works, its just an annoying knawing thing in the back of my mind, knowing there is an update on the market, and i can't have it
Delete the terminal app in terminal by
su
cd /system/app
ls
them find the app that starts with com. something
type rm -> name of the app
update it in market

gives me a read only error, i have to chmod it first right? have no clue how to do that right now, have to look it up. Thanks for pointing me to the proper file though
It'd probably be best to use adb.exe (available in the android SDK) to remove terminal emulator rather than using terminal emulator.
Also, in order to change anything in the /system partition, you need to remount it as read/write.
With adb this is easy:
Make sure your android has debug mode enabled (which I think is by default in all JF releases)
Hook it up to your computer with the USB cable
Open up a command prompt in windows (or whatever other OS you're using that has the Android SDK) and go to the tools directory in the SDK
Type "adb devices" to make sure adb sees your phone, if it doesn't, well uh...it's not working right, and you'll have to figure out why
Type "adb remount" to remount the /system partition as read-write
Type "adb shell" this will give you shell access to your G1, from there you can delete stuff from the /system partition. I think you might also be able to use "adb uninstall" but I don't know if that works for the /system/app folder.
thanks for the info TM will play with the sdk tools and see what i can do, they have been giving me a headache on linux, but then i haven't played with linux in about 6 years.. its come along way. Thanks again for the info wait 2 secs to reload the image
I've noticed that, too. I don't see a reason why I need to update TE, the one I have works just fine.
here your answer in the link below
this will allow you to remove the terminal and install the new one from market

So I was messing around with some of the system files, just trying to learn more about everything and I decided to do a wipe to put everything back to where it was and after I wiped, it gave me an error message at bootup saying that the gapps process had to be closed. I went through the regular sign in and when I got to the main screen, the screen was black. I get the top bar but nothing else.
So I tried reinstalling JFRC33 Lite. Same thing. So I tried installing JFRC33 regular. Now I cant even get by the blinking android. I dont know what the heck is going on but I know all is not lost because I can still et to the bootloader. Can anyone help me out?
Thanks.
try putting one of the updates on your SD card and naming update.zip, and then access the phone via adb shell(if you can) if you can see it with adb devices then type "adb shell wipe all" it will COMPLETELY wipe your phone and allow you to reinstall your update, you cshould be good as root after that, if not then try a .nbh file

Thanks bro! I had no idea you could wipe through the pc.
one of the many things i found when i was trying to control the phone with my computer. i have a script that when i run it on my comp it auto starts tetherbot and hits the up key on the trackball then hits enter to start the proxy, then does the adb forward tcp command and then starts firefox with all the correct settings. i also found a very complicated way to send texts with my phone using my comp keyboard and adb

Oh? Please share. I'm very interested in ways to control the phone from the pc.
Thanks
for the time being it is not an exact science, you need a key map(one found in my thread about the computer app to control phone) and you need to know a few commands. basically to get the phone to think you pressed a button you need to have the computer send the command: adb shell keyevent ## where ## is the number that corresponds to the key you want it to press on the phone. keys are labled 0-85 but i still have yet to figure out what 0 does and a few of the keys don't work perfectly yet but that's being worked on.
secxond you need the command "adb shell am start -a android.intent.action.MAIN -n (*********/*********)" where the *******/******* equals the program you want to start. for Steel you would type:
adb shell am start -a android.intent.action.MAIN -n com.kolbysoft.steel/com.kolbysoft.steel.Steel
that will bring up steel to your home page, after that you can type adn shell input (keyevent|text) if you do text the phone only reads one word, not sure why but i am trying to fix that as well, and if you do keyevent then you need to know what number corresponds to the key you want pressed
here is an example of a script that will start tetherbot, start the socks service, and do the tcp forwarding action
#!/bin/bash
adb shell am start -a android.intent.action.MAIN -n graha.ms.tunnel/graha.ms.tunnel.TunnelConfig ##start new instance of tetherbot or bring current one to front
adb shell input keyevent 19 ###press up
adb shell input keyevent 66 ###press enter
sleep 3
adb forward tcp:1080 tcp:1080
all the commands i have found so far i got by running adb shell logcat and reading the output as i click on different applications. if you need some help with this then i would be more than happy to help, just make sure to let me know what program you are trying to run(if it's a paid app then you will need to run logcat and attach the output after running the app) if it's a free app i'll just install it and let you know how to start the app, then you can write scripts to get your phone to do certain things. i already have a script that wipes my phone, reapplys apps to SD and resets my settings, it's kinda messy but it works

[BEGINNERS] Replacing system files using Android Commander
Replacing system files using Android Commander:
(This post was formally based in the HD2's RTL support thread and revolved around our need to replace frameworks)
so:
1. Download the android SDK from: http://dl.google.com/android/android...08-windows.zip
2. EXTRACT(!!!) the android-sdk-windows to c:\
(make sure you extract the dir - not run the setup from inside the zip file)
3. install Android Commander from http://androidcommander.com
4. Connect your device and make sure it's set to Debugging mode in /settings/applications/development/
5. You might have to set a dir containing your adb.exe file. set it to c:\android-sdk-windows\tools\
6. You will see a Total Commander-like interface. you can then copy the framework.jar file to the correct directory (there's no difference between SD android builds and androids in ROM - the system dir will be shown the same way)
a. Yes, you can replace/delete system files while android is running.
b. (for androids running from SD) Any file copied to /sdcard/android/root/system/X will be copied to /system/X in the system file. The sdcard/android root dir is JUST LIKE your root in ROM androids.
c. Make sure you either created a backup or verified a match in any other way before replacing files like frameworks, zimage, modules, etc.. your android might not boot afterwards (I keep all system.ext2 files backed up so that i can restore them incase i screw something up.)

This workshop was held in #android-learning on irc.freenode.net by XDA Member Adrynalyne. All credit to him for this guide, I simply am taking it and turning it into a guide. Here we go!
You can find the raw IRC log here
Good evening folks, and welcome to my ADB workshop. This is by no means a full explanation on the subject, but more of a crash course to help folks get up to speed, and get more from their devices. There may be some things you already know here, so please be patient and respect those who do not.
Reference Files
http://adrynalyne.us/files/How to install adb.pdf
http://adrynalyne.us/files/Using ADB.pdf
So, lets just start with the basics.
What is ADB?
ADB stands for the android debugging bridge and is used for testing and debugging purposes by developers.
However, we like to get more out of our devices, and its a great way to fix things.
Knowing adb can mean the difference between a paperweight and a working phone.
So, to start with, we will look at installing ADB.
Generally speaking, the Sun/Oracle JDK is required to run all SDK functions.
ADB is but one tool in the SDK arsenal.
So, we begin by downloading and installing the JDK. This can be found here:
https://cds.sun.com/is-bin/[email protected]_Developer
Choose your OS, download and install. I recommend that 64 bit users use the regular x86/32 bit version as well.
Moving ahead, we download the Windows sdk from here:
http://dl.google.com/android/installer_r08-windows.exe
Due to already installing JDK, you won't be stopped by the install process.
Now, if you notice, I installed it to:
C:\android-sdk-windows
I did this because it makes things easier when setting up path variables.
I encourage everyone to do the same, but obviously it is not required.
So, this SDK is handy, but is only good up to 2.2. We want the latest and greatest! (Well I do)
So, we navigate to:
C:\android-sdk-windows\
and we run SDK Manager.exe
If you notice in your PDF file for installing adb, you will notice that you can update, and I made a choice not to include earlier sdk versions.
I won't go into full detail on that, but depending on the version of SDK you have, 8 or 9, it WILL make a difference in using adb.
By default, for version 8 adb.exe resides in C:\android-sdk-windows\tools
By default, for version 9 adb.exe resides in C:\android-sdk-windows\platform-tools
We will assume version 9 in this guide
Really, the SDK is installed and adb is usable right now, but in my humble opinion, its not enough
I like the ability to use adb in ANY directory on my machine.
To do this, we edit Windows's environment variables.
Specifically, the system path.
To do this, we click on start, or the orb (depending on OS), and right click on Computer, left clicking on properties in the menu.
If its windows XP, I believe it brings you into advanced system properties immediatly. Vista and 7 need a second step.
On the left hand side, as you notice I have highlighted in the pdf, left click advanced system settings.
Under advanced tab, we left click environment variables...
There are two boxes here.
We are concerned with system variables, however.
So we scroll down the list and highlight path and click edit.
Ignoring all the extra stuff in here, make sure you are at the end of the line, and type
Code:
;C:\android-sdk-windows\platform-tools
The semicolon allows us to separate it
from the previous path statement.
Click ok all the way out.
We now have ADB setup globally. We can use cmd.exe (I use powershell) and no matter what directory we are in, adb is recognized.
If it is not, make certain you entered the path into system variables, and made no typos.
If you installed to a different location, you will need to adjust the path accordingly.
This concludes the section on installing the Android SDK to use ADB.
This next section will be on using ADB, so please open that pdf now.
Now, this applies to any OS, not just Windows.
Well, with the exception of the USB drivers.
I will not go too much into that, but if you take a look at the PDF, it goes through installing usb drivers for the sdk, and how to download them.
Fiarly straightforward, in that rspect.
Now, to setup our phones to use with the SDK and ADB, we must change some settings.
First, we go to menu softkey, then settings.
We scroll down to Applications and tap it.
Under Development, we will check Enable USB Debugging. Please note the SGS phones are different in this respect.
The USB cable must be unplugged before enabling or disabling this setting.
Once this is done, we are now ready to play with adb
One quick note: If you get device not found/conencted, please reboot your phone. DJ05 has a quirk in it where ADBD randomly crashes on boot.
A reboot will fix this
ADBD= ADB Daemon
Ok, continuing on.
Lets look at installing applications. This is also known as sideloading.
Unlike installing from the SD card, it does not require unknown sources to be enabled.
The command for this is
Code:
adb install packagename
This assumes that you are working from the directory where the file is located.
This will install the application to /data/app.
It will also show sometimes useful errors if install fails.
That is not something you will see from the Android GUI.
Now, a lot of us have probably deleted files with apps like Root Explorer. While this isn't really a bad thing, it leaves behind databases and data for the application removed.
This is where the 0kb applicaiton entries come from.
If you take that application entry name, you can uninstall the extra data via adb.
First we go to the adb shell which logs into the phone.
Code:
adb shell
If we end up with a $, we will want admin rights, in many cases. This is not one of them, I don't beleive.
To get admin rights, you want to type
Code:
su
Look at your phone if this is the first time, it may prompt you to allow access. Else you will get permission denied.
If you are not rooted, this will not work either.
Ok, now that we are logged in, we will type
Code:
pm uninstall packagename
where packagename is the name of the 0kb listing.
Now this seems like a pain in the a** and I agree.
HOWEVER
There will be a time where Manage applications crashes when you try to uninstall it from the phone. In this case, a factory reset, or this method is the only effective way to fix the problem.
Moving on.
How many of us have removed system applications or renamed them? Did you know that you can simply disable them from the system?
Code:
adb shell
su
pm disable appllicationname
This will disable it, and the system will ignore it.
This can be seen as safer than deleting or renaming things, but your mileage may vary.
On the other hand, you can also re-enable these applications.
Code:
adb shell
su
pm enable applicationname
Please note: Not all applications will properly re-enable. I believe a factory reset or reinstall of said application will fix the issue.
Also, application names are absolutely case sensitive.
*nix based Operating Systems see the letter 'a' and 'A' as two different things.
when you log into adb shell, you are playing by android rules
Ok, a lot of us tweak and mod our phones and turning off the device to get to clockwork recovery, or battery pulls, or multiple button holds to get into Download mode are troublesome and annoying at best.
ADB can help us here.
Here, we do not need to be logged into the shell
If we want to merely reboot the phone:
Code:
adb reboot
If we want to go to recovery (works well with voodoo5)
Code:
adb reboot recovery
If we want to go to Download Mode because we need Odin, heaven forbid:
Code:
adb reboot download
Its instant. No waiting on animations or anything else.
Its also handy if Android has locked up, but yet still works in adb.
I for one hate taking my case off to battery pull.
So now we move on to pushing and pulling files.
Sometimes, I don't feel like mounting my sd card to copy a file over to my phone.
I can use this command to push a file straight to my sd card:
Code:
adb push filename /pathtodirectoryonphone
So for instance, if I have test.txt that I want to send, I would type:
Code:
adb push test.txt /sdcard/
and there it goes.
Ok moving on
Pushing files can be done to any directory, however, some are protected.
For instance, /system is going to give you a permission denied or a read only filesystem error.
To get around this, the easiest thing to do is push the file to your sdcard, then log into the shell:
Code:
adb shell
Code:
su
We will then mount the system as writable
Code:
mount -o rw,remount /dev/block/stl9 /system
Then we can use something like
Code:
cp /sdcard/test.txt /system/app/test.txt
cp stands for copy
and it requires the path of the file and destination path. The name of the file is optional
When you copy it, you can rename it to whatever you like.
For instance, if we wanted to backup a file
Code:
cp /sdcard/test.txt /sdcard/backuptest.txt
Now, lets assume you do not have busybox installed.
You non rooted users will not.
Then you must use a slightly more complicated command called dd
This is used like this:
Code:
dd if=/sdcard/test.txt of=/system/app/test.txt
if is for inputfile
of= output file
Not every user friendly, but probably one of the safer copy commands.
Ok, moving on to pulling files.
Lets say you want to get a file from your phone, to modify, backup, etc.
To do this, we simply use adb in this manner:
Code:
adb pull /pathtofile/filename destinationname
For instance, if I wanted to backup ADW launcher in system/app
I would do this
Code:
adb pull /system/app/ADWLaucnher.apk ADWLauncher.apk
And it will pull the file from the phone and put it in the current directory.
Like above, you can specifcy where it goes.
pushing files to the sdcard, it seems prudent to talk about changing permissions.
sdcards are typically fat32, which destroys permisisons, and Android is heavily permission based.
So if you push an application to your sd card, then try to copy it to /system/app/ bad things are going to happen, or the app may not even show up.
So in that case, we use something called chmod.
This is used in this manner
Code:
adb shell
su
chmod 755 /pathtoapplication/applicationname
Keep in mind
you dont want to do this while its still on your sd card.
an example
Code:
adb shell
su
chmod 755 /system/app/ADWLauncher.apk
755 is good for applications and script files.
Just a couple more topics to cover.
Lets go over deleting files.
This becomes especially handy for removing rogue applications.
To do this, we must be in the adb shell.
Code:
adb shell
su
rm /system/app/ADWLauncher.apk
You may need to remount system as writable with:
Code:
mount -o rw,remount /dev/block/stl9 /system
That applies when using chmod as well.
So what I did above was delete ADW Launcher from system/app
However, what if I wanted to delete the entire contents of a directory?
Same thing as before, except
Code:
adb shell
rm -f /data/dalvik-cache/*.*
I just cleared my dalvik-cache with that command
very quick, very effective.
If you just tried that, please reboot your phone now
Ok....this leaves us with the final topic: logcat
logcat allows us to log what the OS is doing, and possibly delve information for when things are not working
its quite simple Reading it is another.
To use logcat
Code:
adb shell
logcat
To logcat to a certain file do
Code:
adb shell
logcat > /sdcard/logcat.txt
Now we let the log settle down to a reasonable amount of data coming in and not a wall of scrolling, then start the app in question. When it gives an error, we hit ctrl-C and kill the adb shell session.
This should have captured enough data to see the error. Now, I prepared an example. A user came to me on IRC, and Google Maps was force closing. Clearing data didnt fix it, Clearing dalvik-cache, and fix permissions did not fix it. In this case, the user did not know how to use adb So I had him grab an app called alogcat from the market and email me the log. This is also a very valid method.
this file explains what the problem was, and highlights what to look for as an example.

QUICK FAQ's
sources: Q&A Section, The Weekly Q&A Section by XDA News Writers (thanks guys)
Q: ‘Is there any way to block specific apps from using my data connection?’
A: Try the Droid Wall application.
Q: ‘I read how you can make changes in the build.prop file on my Android device. How exactly do I get to it?’
A: Install ASTRO file manager, browse to /system, long press on build.prop – Edit – Copy. Press on the home icon then Edit icon – Paste. Connect sd card, edit it, and paste it over from where you copied build.prop
Q: What happens if I update my phone? will I need to re-root it and get the ROM again? will all of my applications get erased? If so, is there a way around this?
A: You will lose your root, but not apps if it is just an update.
Q: I just tried to flash a ROM from recovery on my Android phone and got “Verification Failed, Installation Aborted” What happened?
A: Before you can flash a custom ROM the .zip file must be digitally signed in the ROM kitchen, if unzipped and re-zipped it will lose its verification, this happens often using the Safari browser as it likes to decompress .zip’s. Or if your download is corrupted (download the ROM again) it will fail the Verification.
Q - HTC Location Widget shows "map data unavailable"
A - On the widget, click the pin/then click the windows button/click get more/scroll to download maps/download relevant map (care, maybe a big file). Now exit and click onto map, your location should now be visible :)
Q:So, I moved all the apps on the SD, but is still not enough. How can I free some memory? I could delete the cache of the older upgrade or something else?
A:Do you have pictures and videos? If so, check if they are on the SD card and not on your internal memory. Cleaning your cache helps, and try deleting your text messages threads.
Q: ‘What exactly is a kernel and what are the benefits in changing it?’
A: A kernel is a bridge between the applications and the actual data processing done at the hardware level. The kernel’s responsibilities include managing the system’s resources – the communication between hardware and software components. Flashing different kernels gives you different operating speeds, better battery life, the ability to overclock, and more.

Edit: solved, tried myself

There are a couple other ways posted for folks who have forgotten lockscreen password or pattern, but this methods REMOVES the PIN. for pattern and password follow other methods
This method requires root access and debugging enabled.
*if debugging is not enabled it can be done from any custom recovery
-reboot recovery and follow code
PIN
Code:
adb shell
# sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite> update secure set value=65536 where name='lockscreen.password_type';
sqlite> .exit
# exit
adb reboot
step one
Code:
adb shell
make sure you have # in the command prompt/terminal (if not type su)
step two
Code:
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
you will now see sqlite>in command prompt/terminal
step 4
Code:
update secure set value=65536 where name='lockscreen.password_type';
still sqlite>
step 5
Code:
.exit
you will see the # again
step 6
Code:
exit
you will now be in the path/to/adb command prompt/terminal again
step 7
Code:
adb reboot
Enjoy full access to the device
Now lets say you think your wife is cheating on you (which she probably is) and you want to check her sext messages but return the PIN back when you are done.
Code:
adb shell
# sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite> update secure set value=131072 where name='lockscreen.password_type';
sqlite> .exit
# exit
adb reboot
I find this a bit scary, how would you normally prevent ADB or Recovery hacking like this if your device gets stolen?

I recommend Avast Anti Theft.
When your device gets stolen, the new owner will take the sim card out and put his in huh?
Well, anti theft sends a pre-entered number a warning that an other SIM is in it. Via sms commands, you can turn GPS on, send the location, block root and stuff.
It wont be deleted as it is a system app
I use it.
Thanks for the job, needed this for hacking my bros phone xD
Greets!
hahaha. .... these Feds could of used this method. They couldnt get past the lockscreen. Great read here.

Looks like CyanogenMod is working on securing ADB
Security and You

Many of you may not give it a second glance, but among all the furor and concern about permissions requested by market apps and privacy, all Custom ROMs (CyanogenMod included) ship with one major security risk — root!
We have been struggling with how to handle this for quite a bit, and took a first step with the first public CyanogenMod 9 alpha builds, by disabling the previously-default root access over USB. You can still get adb root access by running “adb root” in terminal, should you ever need it.
We recently merged 3 patches into CyanogenMod 9, to further address this: http://goo.gl/eCjDV http://goo.gl/oWAFI and http://goo.gl/34vai.
What follows is an explanation of the changes, how they affect you and our reasoning behind them.
What do the patches do?
They disable root selectively and in a configurable way. Users will be able to configure their exposure to root as:
Disabled
Enabled for ADB only
Enabled for Apps only
Enabled for both
How does this change affect the usage of your device, and root apps you have installed?
On a default CyanogenMod installation, root usage will have to be explicitly enabled by the user. This means that the user is fully aware that any application that uses root may perform actions that could compromise security, stability and data integrity. Once enabled, the process mirrors that of the current process, apps that request root will be flagged by the SuperUser.apk and the user will have to grant selective access.
Why the change?
At CyanogenMod, security has always been one of our primary concerns, however, we were hesitant to make a change that might disrupt the current root ecosystem. With CyanogenMod 9 we have the opportunity to do things better, whether its the code in the OS, UI/UX, or security – we are taking this time to do things with a fresh approach.
Shipping root enabled by default to 1,000,000+ devices was a gaping hole. With these changes we believe we have reached a compromise that allows enthusiasts to keep using root if they so desire but also provide a good level of security to the majority of users.
What concerns remain?
Many of you reading this are savvy enough to note a remaining hole in this approach – recovery and unlocked bootloaders. The bootloaders are out of our hands, there is little to nothing we can do on that front.
Regarding recovery – with unlocked bootloaders, a malicious user could just flash a new recovery image (without any potential security we could apply) or just dump the data partition. This however, requires physical access to the device. As such, the security standards for this are highly reliant on you, the device owner. Data encryption is available in ICS to safeguard your data. (Warning for emmc only users – encrypted /data means recovery will be non-functional.)
The onus is on you to secure your device; take care of your possessions, and this risk is minimal. Always make sure you take devices out of your car before you go into the mall and remove them from pockets before washing laundry. Common sense is a basic security tool.
But Why?

All true, if speaking of a casual thief- maybe you left the phone on the bar and someone couldn't resist the temptation. A couple of months ago my wife's phone was recovered in such an occasion- got an sms from Avast Theft Aware with the new number, contacted the rather surprised "honest finder" and he decided to return it back to us.
Anyway, two weeks ago went scubadiving and when returning to the car found the window broken and sure, among other stuff (wallets, scuba gear etc) also both our phones were stolen. However, this time it looks like the thieves were not quick to put their own sim card. Actually, it looks like they've removed the batteries, thrown the sim cards away (the're useless anyway as the carrier blocks the sim).
Since then, no signs whatsoever that the phones have been turned on, sims replaced or that someone has tried to type wrong security pin or whatever- no sms notifications, no emails, no webtracking, nothing.
My guess- the thieves sell them for a small fee (20% of street price?) to some lab or someone who knows "how to deal with it"- do a good wipe (not just factory reset) and remove whatever stuff was installed- system app or not- then put them on market for sale as second hand. Or maybe they just wait with patience a few weeks until you stop looking for it?
So, sometimes these apps like Avast, Cerberus and the such work, sometimes not. Better to keep the phone safe and not rely on it being stolen by a stup!d thief...
On the bright side, one can consider it as an opportunity for upgrade
irst I typed in :
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
However, in spite of what he stated, sqlite>in command prompt doesn't appear.
Instead, I get
/system/bin/sh: sqlite3: not found
how do i set sqlite working?
I'm unable to launch sqlite3 from adb shell
I can manually launch sqlite from the folder but not in cmd
You have to install sqlite3 - https://play.google.com/store/apps/details?id=ptSoft.util.sqlite3forroot&hl=en
Is there a tutorial for a password locked screen too?
Is there another way to bypass the pin code lockscreen? Cus´ I´m always stucking on:
" /sbin/sh: sqlite3: not found "
I have installed sqlite from market
any idea?
whoa, you guys are amazing, this worked like a charm on a password locked tablet
polaroid pmid70c
this is a scary concept if you value your android device consider installing a paid service like dyndns and install the paid version of real vnc onto the device and have ssh setup as well this would help to recover your phone in the event it becomes stolen you could ssh into it launch apps view and control the phone remotely via vnc hell even take pictures ,, turn on gps all sorts of cool things

your phone is root enabled? Superuser or SuperSU app installed? Connect USB and run "adb root" and that works?
Try this installer app again https://play.google.com/store/apps/details?id=ptSoft.util.sqlite3forroot&hl=en
I flashed the root feature with SuperSU update zip file in recovery mode, and rebooted.
I grabbed a 'sqlite3' binary made for ARM cpu from the 'net and manually pushed it to my phone's /system/xbin/ directory.
1. unzip this sqlite3 file
2. power on device in custom recovery mode, ('factory mode' also may work, such as in some chinese phones, including my Jiayu)
3. connect USB cable, and in recovery mode, mount the /system directory and any other directorys you will use (see screenshot)
4. open a command prompt (terminal) on computer and run these commands
Code:
[I]adb root[/I]
[I]adb remount[/I]
[I]adb push sqlite3 /system/xbin/sqlite3[/I]
[I]adb shell[/I]
[I]chmod 755 /system/xbin/sqlite3[/I]
[I]sqlite3 -h[/I]
...
exit
adb reboot
* alternate method: if #4 'adb root' does not work, then turn on phone to normal running mode and do:
Code:
adb push sqlite3 /data/local/tmp/sqlite3
adb shell
su
mount -o rw,remount /system
cp /data/local/tmp/sqlite3 /system/xbin/
rm /data/local/tmp/sqlite3
chmod 755 /system/xbin/sqlite3
sqlite3 -h
...
exit
exit
adb reboot
"exit" twice for alternate method.
All this can be done over Wifi instead of USB via a SSH server app.

I can run all the commands fine, but the PIN lock is still there on my phone after reboot. Android 4.2.1, Jiayu Chinese ROM. So method does not work.
help me, im stuck at " error: device unauthorized. Please check the confirmation dialog on your device."
I know this is super old thread but I used this method and combination with other commands I found on internet to bypass my lockscreen on att samsung galaxy s7 phone I had forgotten pin code on.
I was using fingerprint for a couple of months and rebooted phone for an update and it requires pin code first time before using fingerprint again and I had flat out forgot it. When it got to 1 hour wait between input retrys I searched and found this and other methods. I read no methods work unless rooted.
Luckily and thank God I'm rooted and usb debugging turned on and I have adb installed configured and have used with phone before....thank God. Because pretty much every and anything else on the phone is turned off on phone so I keep off the grid.
I know I'm dragging this out but I want to document and reiterate the value of xda. I will try and remember exactly what I did and may just redo it to be sure and list my exact steps.
One thing, I don't have sqlite3 curser when connecting with adb....I have hero2qltatt or something like that .....I'll get corrected with an edit when I go thru again to make sure.
Also, once I got past lockscreen, when I went into setting/lockscreen&security/ on the phone it still showed pin,fingerprint as security but somehow which still baffles me there was a pick for 'swipe' available....but I still don't know how that happened or how it appeared but I kept trying different pin codes to try to reset that which now there were no limits or time delays but still couldn't remember and then I saw a pick for 'swipe' and that solved it all. I rebooted again to be sure and perfect. Then I went in to recovery and wiped cache and now my phone is back exactly as before.
I wrote down the pin code this time.
Eventually soon I will rerun my steps and document exactly and maybe there is already a more recent account but I found this one first and it pretty much worked....thanks.
OK this is what I used:
adb shell
cd data/system
su
rm *.key
reboot
