How To Replace Default Laucher In CM7 With Another One?

Problem :
I'm a Samsung galaxy mini user and i have a doubt. My doubt is that when i installed cyanogen mod 7 on my galaxy mini, Samsung launcher has been replaced by zeam launcher and I'm not able to uninstall it. So, is there any way in which i can replace zeam launcher by some other launcher like Sony Ericsson and make it permanent. (uninstallable).

Solution :
Yes, it's possible to replace the default launcher app. By using a root app called Root Explorer you can do so instantly and easily by following the detailed instructions given below. So, before you follow the steps below, Make sure you have Root Explorer installed on your CyanogenMod 7 rom.

  • Get yourself the apk install file of the new launcher app that you are going to replace with the default one and copy it to your sd-card.
  • Now, Browse to /system/app/ folder using Root Explorer and mount it as read-write from the mount R/W button present at the top of the app.
  • Now copy the new launcher app to system/app/ directory, which is where you can find all system applications.
  • Once you are inside the system applications directory ,search for the default launcher app and rename it to add .bak at the end of it's name. [See example below.]
  • Now, rename the new launcher you copied earlier with the name of the default launcher app.
  • Once done, long press on the new launcher file to get a list of menu options. Select Permissions from the menu (you should see something like below --not exactly the same though.)Then, Set appropriate permissions : Read-write for Owner and Read only for Group and Others. Or more specifically, set permission to rw-r-r. You can also use root explorer permission option to set the permission as shown below :
  • Permissions for System Applications
  • That's all. Now reboot your device and your android launcher should now be replaced with your favorite Home launcher application.
In case if you find the above steps confusing, you can try adb commands to replace default launcher by pushing new launcher as the default launcher and settings appropriate permissions using chmod command of busybox.

However, to better understand the case above, I will present a simple example. Assume your default Launcher name in system/app/ directory is ADWLauncher.apk and you want to replace it with a new launcher be it Xperia Launcher.apk. Now, you copy this Xperia Launcher.apk to system/app/ directory and rename ADWLauncher.apk to ADWLauncher.apk.bak [We do this so that we can use it later on in case we run into problems.] Now, rename the new launcher (Xperia Launcher.apk) to ADWLauncher.apk
and set permissions as rw-r-r (as shown in the diagram above). Now, reboot your device and see the changes take effect.

That's all to replacing default android home app with whichever launcher you have to make it permanent. You can alternatively install the new launcher and set it as default one in Manage Applications settings too. Do let me know if you have any doubts at the comments below.

What Is Odin? How Do I Upgrade Samsung Android Smartphone?

Question :
May I know what is ODIN and ROM? There isn't any official firmware upgrade through Samsung Kies. And I don't know how to upgrade my phone. My current device is Samsung Galaxy Mini GT-S5570 with android version is 2.2.1 Froyo in it. Also, I'm from Malaysia (if that helps). Can u help me?

Reply :
ODIN is a leaked program for flashing (installing) official Samsung Firmwares (aka. ROMs) on Samsung Handsets. Different versions of Odin are available for different Samsung android smartphone and the choice of the version of Odin depends upon your device's model. As for Galaxy Mini/Pop you need to use Odin Multidownloader v4.38 which can be downloaded from http://yagyagaire.blogspot.com/p/downloads-for-galaxy-mini-gt-s5570.html along with other necessary files including roms and recoveries.

ROM on the other hand stands for Read Only Memory. But, here it doesn't intend to mean the type of memory. Instead, it is used as a synonym to Firmware which is a program stored in read only memory. Or, in more simpler terms ROM here means the system that is running in your handset. There are various ROMs including some from Samsung and other from different users/developers open source community out there. While roms from Samsung are called Official Firmwares, systems from other open source community are called Custom Roms as they are customized from the source code of the official firmwares taken as base.

To upgrade your device, you have to collect Odin, corresponding OPS file and latest firmware from sammobile.com or other leaked firmware distributors. And, once you have all the required files you put your device to download mode (Press Volume Down + Home + Power button while your device is turned off to get to download mode) and then connect it to your PC. After that you need to prepare Odin with the firmware file(s) and press Start button when everything is ready. Your device should be upgraded within few minutes ranging from 5-10 minutes. Note, that you will fail to flash firmware if you don't have proper Samsung drivers installed on your PC. Installing Samsung Kies installs the required drivers along with the software.

That was just an overview of how you flash the firmware on any Samsung device. For your case, (i.e. for Samsung Galaxy Mini GT-S5570 smartphone) you can follow the detailed instructions at this article. However, since you are from Malaysia you will need to replace the firmware (said in the article linked above) with the one that is released for your device from sammobile.com. For this you can check your PDA and baseband by dailing *#*#1234#*#* in your Phone keypad and then noting down the details. Then you can match the first seven digits from the code you obtain with the firmwares available at sammobile. Do let me know if you have any doubts at the comments below.

What is Signature? How can I have one in my messages?

Question :
My bro is using blackberry mobile. When he sends any mail from mobile to me i'm just observing that message and at the bottom of the mail  I'm seeing like "Sent from black berry".

Whats does that mean and why it is shown? Also, can I have same with android ??

Reply :
That's called signature.... A signature is something that is appended automatically (by an app) at the end of every message you send via the application. It's a common case with forums and other communities and if you have participated in any forums then, you should by now have a fair idea about it. This article on Wikipedia will provide you with enough details needed to know about signature blocks (or simply signature).

However, in messaging it's possible when you use some kind of application to send messages (provided that the app support signatures). Your bro might be using some kind of application too that let's him add a signature at his messages and judging from the above report you made it seems like he also don't have clear idea about it since he is using the default signature (set by the app). And, it seems he is using Blackberry messenger application, if my guess is correct. You can ask him to confirm that.

I've not heard of it being possible with regular SMS.  Similar signature can be used if you want to send messages via Yahoo messenger app, so give it a try. I think Facebook for Mobile, Friend caster app also make use of signatures; however, I've not tried any of those either. Hope that's clear. If it is still unclear let me know at the comments below.

Adobe Flash Player 11 For Stock Android Firmwares

Question :
I own a Samsung Galaxy Mini and heard that it doesn't support official adobe flash player app. I would really love to see flash sites on my device so can you tell me how can I run flash on my handset with stock firmware. I've heard that flash player works on custom android ROMs, so I thought it just might work with stock Gingerbread too.

Reply :
Yes, adobe flash player works fine on custom roms on galaxy mini as well as on other device with ARM v6 CPU. However, I am not sure if it works well on stock Gingerbread firmware. But, you sure can give this a try and see if the flash player works fine on your stock Gingerbread ROM.
Download the files from step 1 and 2 below and then follow rest of the steps to install flash player on your device.
1. Download Adobe flash player version 11 : Adobe_Flash_Player_11.0_(11.0.1.152).apk

2. Download Lib files : Lib.zip

3. Install the flash player app on your handset using adb install command or by copying it to sdcard and then installing it manually.

4. Now, extract the lib.zip file and you will get few lib*.so files.

4. Then, Copy all these lib (*.so) files to /data/data/com.adobe.flashplayer/lib directory(folder).

4. Set permission of lib files as rw-r-r --Read & Write access for Owner and Read only access for Group and Others-- using Root explorer ( I believe you have rooted phone). Or if you are ok with terminal run this command in your terminal emulator or in ADB shell :
busybox chmod -R 644 /data/data/com.adobe.flashplayer/lib

5. Reboot your smartphone and then run a browser and visit any flash site to see if it works.

That's all. You are now ready to enjoy flash within your android device. If the above mentioned steps don't help you then make sure your browser supports flash and flash plugin is not set to off. Dolphin HD and Firefox are great browsers so just try with them. Also, if you are sure everything is set correctly and followed the procedure above correctly but if flash still doesn't appear in the sites then try again by rooting your device.

It should now work fine since someone already tested it a confirmed it to be working. However, do let me know if it works or not at the comments below.

What is Rooting? What are it's Advantages and Disadvantages?

Question :
I have few more concerns about rooting the cell; means I read a lot that you can do anything with one's cell phone once you get root access. But after i rooted my cell, i didn't find any difference. The main difference was that i had access to system files. I don't know what to do with those system files, I can't even manipulate any file, as i have no idea what they do. I thought that after rooting, I will get lots of options in settings menu and all other administrator options. But there weren't any. So, what exactly does rooting do to my smartphone.
Reply :
Rooting exactly is the process of breaking through the security that is put by the OEM on any handset to smart phone. It is just like obtaining root access in your Linux PC or having administrative privileges in Windows system. In other words, rooting provides you with superusers access meaning you will then have the ability to browse system files, edit them, customize your device and take the control of your device in your hands.

Here's are few advantages of rooting your device :
  • You get access to system files.
  • You get to run many applications and other tweaks [also known as root apps as they require you to have a rooted device to run/function properly.]
  • You can remove bloatwares and other system apps that comes pre-installed with your device.
  • You can customize your device to your liking (change fonts, themes, etc ) with the help of various apps and tweaks.
  • Ability to backup, restore and manage applications and the data.
  • And there are many more such as removing ads from applications and browsers, etc.

The real problem with you seem to be you are unknown of how you can do these all things on your android device. In reality, most of the task above require high knowledge and they are done with apps or tweaks in the market. If you just search for root apps in market you should be able to get a helluva lot of them --some for free and some for a price. You can try the fee ones and see what you can do with them. Here (http://yagyagaire.blogspot.com/2011/09/top-ten-android-applications-for-rooted.html) are few apps to name that will help you get started exploiting your rooted smart phone.

While there are many advantages of rooting, like other cases it also has disadvantages. One who doesn't know what he is doing will probably damage his/her device. Rooting provides system access as a result some malwares or applications may steal your private data and information. Not, only that there's also a chance to brick your device if it is not done properly.

Despite these people root their device to enjoy all the freedom they get by rooting. However, rooting will mean nothing to you if you don't know much about and how to use it's power to get the best out of your handset.

What Is Root Directory?

Question :
What is root directory? I am instructed to copy a file to root directory at this article (http://yagyagaire.blogspot.com/2011/12/rooting-samsung-galaxy-pop-with.html) but I can't seem to find it. Can you explain it in detail and tell me where can I find it?

Reply :
The root directory is the first or top-most directory in a hierarchy. It can be likened to the root of a tree — the starting point where all branches (other folders or sub-directories) originate. For example : The C:\ drive in your PC is root directory and folders inside it are called child or sub-directories. Similarly, D:\ , E:\ or any other drive are root directories.

In the case of sdcard it's a removable disk that is mounted in your PC. The first window you see by opening it is called root folder and in the article above, you are simply instructed to copy it to this folder and not inside any other folders within the /sdcard/ directory. You can even view this by using root explorer and navigating to root (usually denoted by /) directory.

For your information, you can simply ignore it and just copy and paste it inside sd-card you mounted in your PC.The above article asks you to do so because it is easier to find the file in recovery if you don't paste it inside other folders. Also, some recoveries might not let you navigate inside folders in recovery mode so, it is useful in such situation too.

Hope that was clear. If you still have doubts then this Wikipedia article on root directory should help you learn more.

How To Solve Boot Loop Issue in Samsung Smartphones?

Problem :
I have few doubts regarding my Samsung galaxy pop (GT-S5570). I think i may have bricked it.

Actually what i did was, first I rooted my cell then after that i installed clock work recovery mod and then using recovery mod options I partitioned my SD card. This resulted in formatting of my SD card. After that i thought of factory reset as my internal memory was getting full, so from settings-> privacy menu, I click on factory reset option and it restarted and took me to CWM recovery options, there i selected wipe data/reset and after that cell restarted and then it shows Samsung logo and again keeps restarting.
Is there any solution for this problem else than going to Samsung service center ?

I have no idea what i did to my cell... but i want to resolve this issue asap.


Solution :
Yes, there's a solution to get out of this problem without visiting the Samsung service center. Luckily your device has not been bricked and this issue can be solved these simple steps.

If you haven't done it already remove the battery from your device to power off your device then insert it back to your galaxy pop gt-s5570.  Then follow these steps :
  • Go to recovery. Press Home + Power buttons at the same time while your device is turned off. 
  • Now, wipe data and cache and reboot.
Hopefully, that should solve the problem. If you face the same issues again then, there's a problem with your firmware/ROM and thus, you will need to flash (install) it again on your device. You can flash this latest Gingerbread firmware on your device by following the instructions at http://yagyagaire.blogspot.com/2011/12/how-to-upgrade-samsung-galaxy-pop-to.html . After that your device should run fine. Be careful not the install CWM recovery again if you are not going to flash any custom roms.

Also, since all this resulted from the problem of low internal memory, go through this article to solve the problem with easy and step by step solutions.

Will Formatting SD-Card of Android Device Prevent It From Booting Up?

Question :
Does deleting folders like ".android_secure" on SD card cause interruption while turning on the phone? or Can I delete all the folders on it.
Answer :
No, probably it won't interrupt the booting process --meaning your device will boot fine even if you delete all the folders in sd-card or format your sdcard. However, some of your apps will not work since '.android_secure', Android, data and few other folders (especially those whose name starts with a period(.) sign are created by system (Android OS) and thus are important folders. '.android_secure' folder holds apps that have inbuilt a2sd support and they are installed in sd-card by default even if you don't have any custom a2sd script. Similarly, other folders mentioned holds data/cache along with some parts of applications. So, removing them means making some of the apps disappear from your App Drawer or from functioning them properly. This may require you to re-install all those apps to make them working again.

So, in conclusion it is better not to delete all the folders in your sdcard. But, in case you need to make sure you keep the ones mentioned above and other system folders and remove remaining ones. That would prevent you from having any type of trouble with your device.
