I have been reviewing many forums and blogs to see how to root Samsung S Duos. Though I could root my phone easily I was unable to boot to Clock Work Mod recovery. However I could figure it out and the whole process is explained below.
There are two methods for installing CWM : Temporary and Permanent.The one I am explaining below is temporary. If you are trying to install a custom ROM, this will suffice. You do not have to look for any other methods. Apart from this rooting mentioned below, what you would need is a Custom ROM file! I will be explaining how to install a custom ROM in other post. This explains the initial step, rooting of Samsung S Duos.
Please keep in mind that you need to read each and every line patiently. Read everything twice then start with a calm mind. I promise, you no longer need to search for another forum if you follow everything correctly.
Requirements (You can download it clicking on the links, no need to google it again. Worth reading, huh!)
Rooting Kit contains following files : Odin Tool, Recovery.tar, Stock Recovery.tar, CWM Super User. Download and extract the files to your system. You need to extract Odin ZIP file again to view the executable file.
Download and install Samsung driver in your system. Reboot the system if it asks for the same. Otherwise no need to reboot it.
Now, system is ready with rooting per-requisites. Next step is to reboot your Samsung S Duos (GT- S7562) Phone into recovery mode. Read this carefully. Make sure your phone is charged above 80%. Now switch it off and remove the battery back case. Now hold down the Home Key, then Volume Down Key and finally press Power Button. Now system will reboot into recovery mode. As soon as the warning screen appears, release the keys. You can see instructions like press Volume Up to continue and Volume Down to cancel. Yes, you should press the Volume Up key to enter into Downloading mode.
Now connect your USB cable to your phone and to your system. Then open Odin.exe file.
Once Phone is connected, you can see a Value and ID: COM field. This shows your phone is identifiied
Now you have to ensure Auto Reboot and F.Reset Time and PDA fields are ticked.
Next click on the PDA button and select the Recovery.tar file from the downloaded location.
Take a deep breath, see everything is correct as mentioned in step 6 and 7 and click on start.
Wait until the top left column shows PASS. Make sure cable is not removed in between. Now read the next step two or more times until you understand it.
As soon the PASS is shown, system will reboot. Now remove the connected USB cable and the battery. No wonder, do it before the phone starts beyond the initial Samsung Logo with model number. You have enough time, so do not be panic but do it with care. important thing you need to remember is, your phone should not be restarted fully. Because, what you have done, installing Clock Work Mod recovery. But this is temporary, as soon as your phone is restarted, system will restore stock recovery image replacing CWM. So if you restart your phone into normal mode, there will not be any effect of what you have just did. So ensure phone is not restarted fully.
Now we need to restart the phone into CWM recovery. This can be done by down Volume Up Key, Volume Down Key, Home Key and then press Power Button. Once the system is started and Samsung logo is shown, release the keys and you will reach CWM recovery menu. This step is bit difficult, if you fail to boot to CWM recovery, you should remove the battery before it fully started. Otherwise, as mentioned before, system will remove CWM mode and you have to repeat steps 3 to 10.
Once you reach CWM mode, first thing you need to do is to take a full backup of your phone by selecting Restore/Back Up menu. Remember, recovery menu do not support touch interface. You have to use volume up and down keys to navigate and home key to select.
So this is how you can install Clock Work Mod temporarily for installing Custom Roms. Each time you flash recovery with Odin, it increases the flash counter. Also, if your phone is rooted, you will see a yellow triangle while booting. Though CWM is replace while rebooting, phone will be in rooted state.
Android’s Ice Cream Sand witch (4.0) is a very smooth mobile OS. Its aesthetically pleasing interface has attracted many of the users. Though the official version is available for a few devices, there are unofficial versions available from various forums and communities like Cyanogenmod.
I have found two stable ROMs for ZTE Blade in a forum. I tried it in my Idea Blade and it was awesome experience. It was very smoother and faster than the gingerbread. It has option to enable to GPU acceleration making the device work faster. ICS’s new dialpad and UI is very interesting and pleasing too.
ICS roms need atleast 180MB system partition to install. It is possible to install it in Idea Blade since it has 220MB. Well, these custom ROMs are built from Cyanogenmod 9 and are experimental. Having said that, it do have issues. I faced keyboard lag in my Idea Blade. Also application crashes occurred. Still if you want to try and experience how ICS work is, you may try from below links. I found Tilal’s version is more stable with me. I just placing the forum address below so that you choose independently.
I have tested another ROM AOKP(Android Open Source Kang Project) based CM9 Remix 6.6.9. It is the most stable ICS ROM for Idea Blade. Since the phone has only 256MB RAM, it is advised to creat Swap partition of another 256MB using ROM Manager or through recovery menu. You can download this rom from here.
See my previous posts for instructions on how to flash a ROM.
Cyanogenmod has released a release candidate for its latest ROM based on GIngerbread 2.3.7, Cyanogenmod 7.2. This is the final release in 7.x series and is coming with some couple of back ported features and fixes from 4.0, Ice Cream Sand witch. This particular version supports 20 new devices and in a total of 70! No official confirmation on date of final release. I had tested this ROM in my Idea Blade and found very interesting.
Comparing with the previous version, 7.1, this version has improved a lot. A notable change is predictive text dialer. Now you can directly search for a contact from dialer by simply pressing the numbers. This is indeed a good thing. Next, it supports installation in SD cards. Yes, previous version also supported this feature, then what is the new thing? It is, now you can install any application, I said any, to the SD card by default. That is interesting, no!
ADW is the pre-installed launcher in it. With some tweaks you can make it more faster. I prefer not to install any other launchers unless you are using a high memory device. This version has cyanogenmod’s propitiatory features such s theme support, DSP equalizer, and CPU overclocking etc. Unlock screen options are updated. Now you can completely disable the unlock screen or change its style. Also, you can move the notification bar to the bottom of the screen. This option is available in the tablet tweaks.
One major issue reported with this RC is that, it eats battery like anything. Battery is draining fastly and also some of the applications are crashing. After reviewing the overall performance, I PRESUME 7.2 will be a good alternative.
Idea blade is customized version of ZTE blade.Though ZTE blade supports Cyanogenmod Idea blade do not supports changing ROM. Idea blade has only 256 mb of ROM. Even clockworkmod cannot root this phone.
Here is a method to root Idea Blade. Install Z4root and it facilitates rooting of this device. This software supports both permanent and temperory rooting. Install this software and permanently root your phone. Once rooting s done with, system will reboot.
Additionally you can remove the preinstalled softwares from this device. Install Root Uninstaller from Android market. You can remove the unwanted or not frequently using softwares and games etc. It is recommended to remove the preinstalled launcher and replace it with Launched Pro for better performance.
