[Q] Samsung Galaxy S duos s7562

xpacguy · Sep 30, 2012

Do any one have performance issue with Samsung Galaxy S duos s7562.
I am very much disappointed with my device as it will get stuck on screen. Huge Lag time. Will take time to go to application after clicking on icon. Cannot play HD videos. While receiving calls the screen will go black, You can hear the ring but cannot see anything on screen. Any help will be appreciated.

I am sure if the devs come with a solution for the network problem on cm11, I don't think we can use the dual functionality of s duos on cm11. So, how many of you use both sim slots of s duos???(I use only one)

My sis also uses only 1... Idk when she'll get to use cm 11 on her s duos

KlinkOnE · Feb 3, 2014

pretty sure there will only be one sim working like all custom Duos roms. Of course i use both sim thats why i bought this device.
first: cheap calls & sms
second: free data
would be nice to have both working but propably never will...

Hi,
Press The following combination for booting into recovery. (Works fine for me)
Keep all of them pressed until you see the samsung logo and then release them all.

Vol. UP + Vol. Down + Home + Power On

CWM and Odin is attached. Flash this CWM package using odin (make sure you reboot your phone into download mode for using odin)

I'm NOT responsible for any brick or other mis-happening. I tested it all on my galaxy S duos and it works fine.

Edit : CWM 6 replaced with CWM 5and reuploaded. CWM 5 works much smoother for me.

is it CMW5 or CMW6?It's not working for me i.e i can't install recovery zips from ext-sdcard.

XxSTOMPERxX · Feb 3, 2014

Before flashing the cwm zip
Try deleting or preferably renaming install-recovery.sh in root/etc folder.

Press thanks if i helped.

No mate, the network problem still exists. The newest build( cm11 kitkat 4.4.2) is very smooth and usable. Graphics aren't very smooth, so games are kinda laggy.

@candy_ass,
Are you using the Odin method root. Its hard man, better use unlockroot pro it is fast and hassle free

gone unnoticed, this turbo boost mod has significantly improved the speed of the system, especially opening apps and eliminated lags.
I recommend it to everyone.
for those unwilling to read the whole topic I summarize

requirements :

root ( of course)
custom kernel
init.d support
cwm recovery

just flash from recovery and follow the instructions , as a precaution make a Nandroid backup first .

What does it do? simply creates a ram swap file in the unused space of internal memory of the phone.
internal memory means the cache, data and and system partitions and does not affect the space used as storage. (you can choose whether to create a swap file in one, two or all three partitions)

there are already mods that do this on the external sdcard but the speed is slow , while the internal memory is much faster.

no other mods so far has given me smooth over this .

to see if it works type from terminal:

cat /proc/swaps

you will see all the swap partitions and their use ( note that there is already a default partition zmem ( zram ) in physical ram )

you must flash the zip file in recovery mode, it's not an apk.
you must have root and clockworkmod recovery installed

CWM Error in rooting Samsung S Duos

Hi Vikas

I Have followed the steps you have mentioned here and till step 11 everything was working fine.

Now before moving to step 12 there are two options. Either the phone is to be disconnected from PC or let it remained connected. If phone is remained connected it will not boot as when the phone starts it shows battery charging status. So I removed the phone from PC.
After that I followed step 12. The phone boots in Android System Recovery <3e> mode (Rather than in CWM recovery mode). In Android System recovery mode Home button does not work and Power buttons is used for selecting any option. Further there is no option of "Back and Restore" neither option "install zip from sdcard". The options available are:

Reboot the phone
Update from external storage
Wipe Factory Setting
Update from cache

When I choose option "Update from external storage", next screen shows the zip file "CWM-Superuser-3.1.3.zip" (which I had copied on external memory card) alongwith some other folders stored in memory. I selected "CWM-Superuser-3.1.3.zip". The updation started but an error message showed "E: Signature verification failed" and the installation was aborted.

I have tried several times the whole process but getting the same error.

Please help about this error

Here is the full guide. If you like, please press the thanks button,

CAUTION : It will VOID your Samsung Warranty and set/increase your custom flash counter.
You will also see a yellow triangle below Samsung logo during each boot.

Please take a Full NANDROID Backup using CWM once CWM is flashed. This is useful in case you want to return to Samsung Official stock ROM or in case something goes wrong.

You can flash back to stock recovery if you don't need CWM any further OR if you want to remove the yellow triangle.
