I successfully flashed recoveryTWRP302.tar.md5 using Odin.

But when I boot into recovery by pressing Volume (Up + Down) + Home + Power buttons, it gives me the same default recovery as in the quoted post above.

I even tried to reboot to recovery using adb reboot recovery but with no luck.

Kindly help, what I am I doing wrong ?

    Samsung GT-S7562 CyanogenMod 11.0 Android 4.4.4

    Unofficial Release


    I proudly present my first Android related work.
    The GT-S7560M has a similar hardware except the dual-SIM RIL, so the kylessopen firmware (thanks to jonypx09 and others) was a good initial source.
    I reverse engineered the stock Java Radio Interface Layer, and based on that informations, I restructured the kylessopen’s sources.
    Finally with my custom telephony-common, telephony-msim java layer, and with the stock rild, and libril*.so binaries, the GSM connection works.

    Important: This is an unofficial release. If you find a bug, please send a feedback in this thread.
    If you have a problem with the installation, write it down in the Q&A thread.

    Changelog:

    ROM: http://uploaded.net/file/pionx3a0 mirror: cm-11-20150205-UNOFFICIAL-kylessopen-RC1.zip
    Updates for RC1 (flash with TWRP):

    CameraFIX_v2.zip This will fix the front and back videocamera. Before install this, disable Viber's videoConverterService with DisableService app (Play Store).
    If your battery quickly discharges on RC1, disable all bluetooth service (org.codeaurora.bluetooth, Bluetooth Share) with DisableService (Play Store).

    Comments:
    • Working Radio Interface Layer for both SIM card
    • WiFi direct is not supported, so you can't enable. Use Bluetooth, Dropbox, email etc...
    • If you want to install Viber, before the first start, disable Viber's videoConverterService with DisableService app (Play Store).
    • The "OneL+ Lollipop" theme with "IdeaL Theme Dark"'s icons is beautiful.
    • To prevent sound disruption, enable the equalizer.

    About Google Apps, and GService Bug
    • Fixed with all releases after rc3. For reference see below
    • Latest gapps (ver. 7.x) has issues, and eat our baterry, so I recommend to install the package that I linked, disable autoupdate in Gapps, and disable GPlay's CheckWifiAndAutoUpdate service with DisableService (from Play Store).
    • If your Gservices app updated to the version 7.x, you can easily downgrade to 6.x
      (you can do this, if you installed my linked package or earlier):
      1. Settings-->Security-->Device Administrators-->Uncheck "Android Device Manager"
      2. Settings-->Apps-->Google Services-->Disable-->Yes, you want to remove updated version
    • Recommended gapps: pa_gapps-modular-pico-4.4.4-20150117-signed.zip

    Hi all,

    I bought a One M7 a few weeks ago to replace this slow hardware, and I sold the GT-S7562 on last Friday.
    So I won't release any future updates for this ROM.
    Thank you for the feedbacks and the lot of thanks.

    Have a nice day,
    András
