Did u. Do Factory reset

Option 1(easy but I do not recommend it): Settings ->account & sync ->Menage accounts -> click your google account-> delete it.
Option 2. Enter in CWM. Hard reset your phone. All data will be gone.

Only in ICS you can delete the primary account.
In others version of Android you have to restore the phone.
Settings-Privacy-Factory Data Reset.

You can use Root explorer to delete the file "account.db" in : /data/system. Then reboot.

Remove mlab.launcher from micromax a87..
Those who want to remove mlab.launcher or want to uninstall it .. just download a lite launcher like holo launcher or any other.. and copy it to /system/app and change is permission to rw-,r--,r-- and then install the app from there .. that's it .. yea for safety you can confirm the change by freezing the m.lab launcher from root installer and restart your mobile to check whether .. you are getting any error if not then.. voila.
you can now remove the mlab.launcher from /system/app
.. inform me if any error occurs.

how to change the permission can you guide me thruogh

here you go
the best way to do it without flashing ur previous rom or ny thing like that.....
consider it like this you uninstalled ur launcher now a message will display saying 'launcher not working force close' now do nothing just turn on ur internet or wifi connection then go to play store from your pc log in with the same account you have used for your phone find holo launcher now just press download,now depending upon your phone internet speed it will automatically start downloading in ur phone after that it installs and finally its done after this ur finished u can use your phone but still if u want u can chage the holo launcher to system app by using link2sd app......press thanks if I helped

Sideloading help.

I recently used the Nook Developers guide to sideload apps onto my Nook Hd, And all went well, but when I installed Injustice, I get ''failed to load you may have not installed this app'' or something along those line, could anyone help me fix this problem.

Have you moved the application data to your sdcard?
To install this game you need the apk + the data. After downloading the data it will be in a folder named om.wb.goog.injustice i think. Copy this folder to /Android/obb/ (on your sdcard) and then run the game
It should work fine after that
Please press the thanks button if i helped!

Well I installed using command prompt as it is the easiest way to sideload on the nook HD without rooting the device, I tried locating the file you said but I can not find it.

The files don't come with the APK file. You sideloaded the APK using ADB. You need to copy paste the data to your device which is over 1 GB I think. It's a separate file. Ughh you're making it sound harder than it is. It's extremely easy. Plus there are tens of easier ways to install apps on your nook.

Ok and were might I find this file which is over 1 GB? and I thought this was the essayist way to donwload incompatible games to the nook HD, All help is appreciated btw :laugh:

Feel free to click the thanks button. Lol
Just use Google to find data for your apk.. Search "injustice apk + data" and you'll find many results.
One of the ways to install Apps is installing another store on your device other than Google Play Store.
Or if you want to sideload apps easily without command prompt you can use APK Batch Installer.. Or use apkinstaller.

The most common error for sideloading is the resolution or graphic chip incompatible errors. Sideloading app data should not be the problem, try to download a fresh apk from the market and copy Data
It should work fine

so I downloaded the apk+data file for injustice and took the data file and put it in the android/obb directory on my device (I don't have a sd card if a sd card is required please tell me) and I still got the error message, so I decided to turn airplane mode on and the game started up and I got the opening cutscene then it loaded and booted back to my home menu, should I have used the apk that came with the data file or will any injustice apk work?

Hmm... I don't really know.. Maybe your tablet is just not powerful enough to run the game. That's probably why it closes

trojens and malware free android

Holla guys....
So, guys since a time I was thinking to post this but haven't got time.....
Recently my head was collided with the so called trojens like ENGRILS, ENGRIKS, com.android.system.UI , and also a virus naming PORNCLUB.
GOD knows from where they have been automatically download to my system...!!
Working signs of these viruses:-
1. They regularly dowload the third party apps without the permission of user....
2. These viruses convert themselves system apps which cannot be uninstalled... and even if u try to disable them or force stop they restart in short go
3. Several apps starts crashing down...
4. Your Android will starts hanging over again and again...
5. Phone starts heating up like hell...
6. And if they are powerful they can even cancel the root previleges in your Android. In simple words they will unroot ur mobile and after that frameroot will not create any difference. ... (as happened in my case too...)
So how to get rid of them in just some of steps:-
1. Just go to recovery mode
2. Then clear cache ,dalvik cache also for ur system from there
3. If it does not work... them simply connect ur android to pc via data cable
4. Then via odin flash original firmware to ur android and go to recovery and clear cache...then re-root ur android with frameroot..
5. Then install ur old rom and keep rocking...!!!
Congo fellas u have just killed engriks virus....and and and don't forget to hit that thumbs upp if u like my work.....!!!
Adios...

deleting all apps data

Hi XDA members
is there a way to delete all applications data in one step without making a factory reset ???
I know I can delete app data for every installed applications
but I ask if there an apk or any way to delete all the applications data just in one step without factory reset .
Thanks in advance

any help ??

any help??

no reply at all

To delete all apps data must make your phone look like reset. Manually without resetting you can go to '/data/dalvik-cache/' and delete everything and reboot in case you have root and a root explorer
