    • Ok first of all no need to panic ,it happens while learning ,i’ve bricked my device twice !! , Now Make a complete wipe , do a factory reset in CWM recovery and try to flash again ,both kernal and rom ,if still problem persist feel free to ask , u can also do P.M/mail to me.

      • i was using this rom from last 3 months and was my favr8 rom for my galaxy y duos s6102. recently i found new rom and flash that rom. i had backup my previous rom (xperia for but soon after the new rom applied my phone stuck on boot animation.still i cant find the way out i tried to re apply my previous rom,again apply from backup but it now shows md5 mismatch…
        pls reply if any possible ways to get outta this….thanks in advance

    • You should do full wipe then flash , and i think you should download Xperia duos first ,make wipe and flash it, it should help ,and i don’t have this phone ,it’s with my friend ,so I’ll try to manage if possible ,mean while flash xperia .

    • No it is recommended to be on stock Rom but it’s not needed, I’m making ics themed Rom for duos and to test i just flash it after wiping system and data .download xperia duos and make wipe, flash it., still problem then say.

  7. Great ROM and kernel. I’ve installed (yeah, that’s the Windows in me) TD 1.5 v1525, and now cannot add ‘sound’ as a ringtone to a contact. I get the “Sorry! Please take a log” “Process android.process.acore stopped unexpectedly. Try again. Force close.” I’ve tried clearing the Contacts and Contacts Storage cache, stil no joy. I restored from nandroid to factory image and the add sound as a ringtone function works, but going back to TD 1.5 v1525 with the BDSky kernel, the aforementioned function give the error mentioned above. Not a big deal, but thought I’d mention that as a potential bug.

  8. I have tries 3 different roms including technoduos and xperia duos but when i try to install the roms it says

    E:\unmount\sdcard cant unmount sdcard

    Install from sdcard completed

    But the rom is not installed..

    Could you please help me with the issue?

  9. Works great, looking awesome… but one thing I need is to force use UMTS(3g) Network, in original firmware there is a way to set UMTS only mode. Is there any way or app to do same in your CFW ?? please help me.

  10. Tried searching each any every site available on internet but i havent got any success

    Let me list down what i did and what happened.

    What i did?

    1) Tried installing the steps mentioned at the below post
    2) Installed the ROM but as it was written “Flash ICS Kernel with CWM Recovery… No need to Flash kernel if you have already.” i didn’t flashed the kernel
    3) Rom was successfully installed and the phone was rebooted

    What happened?

    1) after the successful installation of ROM my phn rebooted and stuck at SONY logo
    2) I am not able to boot into recovery mode
    3) Flashing the kernel via fastboot shows an error “Your device must be rooted first” but my phn is already rooted
    4) I have already taken Nandroid backup of my previous ROM but nor able to restore it as i am unable to boot into recovery mode

    I also tried updating the phone software by using PC companion but it shows error phn software not available

    Let me know if you need more details for troubleshooting.

    Thanks in advance 🙂

  12. I followed the tutorial correctly only when I install the kernel, the system does not start for more animation on the screen when the system will load what can be?
    and alias kernelflasherv2 only installed one. img not know how to use

  13. hi,
    First of all ,I would Like to congratulate you for developing such a user friendly site ,specially for beginners like me.
    I have tried all three ROMs ,and sadly I had some trouble in each 😦

    with the Xperia ,but I could not find the setting menu in it,I needed to find sim manager. to manage data service.

    Then I tried TD 1.5, I must say I loved the interface and graphics but “root browser ” kept on crashing . More over screen lock was not working and ” home” button was not responding ( the one which brings us back to the home screen from any where) I could not find the “task manager”.

    And finally I tried TD 1.0 ,Its working fine but is not as attractive as TD 1.5. I am not able to increase the RAM space ,It is already 832 Mhz. I have heard of creating a partition in sdcard and then system uses it as internal memory , how to do that ?

    I am using samsung galaxy y duos with 8 gb memory card.

    • Also in TD 1.5 ,I am getting following error
      “a2SD script does not run properly ,better do ” a2sd check ” in terminal emulator ”
      How to do that.

    • 1. for xperia i’ve updated my post and given steps for getting settings work in ROM , real all and follow carefully you’ll get it.
      2. As you are having problem in ROM follow steps given at end of 2nd fig in post your problem’ll get solved move any app to sdcard use link2sd or DroidSail from market and to use swap partition as ram :
      & hope i helped You..

  20. question 1:- tell me 2 or 3 TOP ROMs for my galaxy y duos keeping in mind battery performance and UI
    question2 – i installed TD 1.0 and now if i wanna upgrade to 1.5 do i have to download TD 1.5 zip file again or there is any update file available?
    question3- tell me the best battery saver or task killer app that works and kills the background appss without even asking
    THAnks in advance 🙂

    • Answer of first : TechnoDuos kernel + xperiaduos rom, actually rom really dont matter lot , its your kernel , background app,free memory, app settings like backlight and all that matter most in battery and performance.
      second ans: yes you have to download it again !!.
      3: try advance task killer , and for info , android os itself have a task killer and memory management system , so mostly it do not need any external app for this purpouse unless you are having tons of app , you can use V6 supercharger script for memory management , i hope i helped you well .. enjoy ..:)

  25. can u give any pirated andriod 4.0 link which u find the best and easy to flash

    • Pirated word is not proper as its android so all opensource..and in your phone 2.3.6 is only available , any rom displaying 4.1/4.0 is just a simple themed and customized Rom..and changing rom’ll not affect hardware of mobile..
