    During installing ” UPDATE-SuperSU-v1.25.zip” i dont have ” apply update zip” can u help me with this situation.

    1. Did you put the SuperSU.zip to the SD card? It could not be found if you did not copy to that storage.

  2. In recovery mode just shown;

    Reboot system now
    Apply update from ADB
    Apply update from external storage
    Wipe data/factory reset
    Wipe cache partition
    Apply update from cache

  3. I did everything.. and all done ok. with PASS ICON in ODIN….

    BUT in step B: Installing SuperSU via CWM. i can’t find any option saying “”install zip from sdcard.””
    i just only See STOCK recovery options that are Reboot system now
    Apply update from ADB
    Apply update from external storage
    Wipe data/factory reset
    Wipe cache partition
    Apply update from cache

  4. But @kim Bubble after using appy update from “external STORAGE” it says
    E: failed to verify whole-file signature two times

    den E:signature verifcation failed

    1. Oh boy you’re in trouble. What build numbers your device have? Since this is only a ported CWM, I will refer you to Chotu’s XDA-thread and post that issues and let everyone knew.

  5. i too faced the same problem as AK….at the final stage, i got an error msg of….failed to verify whole signature….in some other thread, i was told to take off the battery once the cwm is pushed using odin….n the re assembly the battery and copy the super su file to external card…they said it should solve the signature failure problem……………i tried that also….but still same probem………..what next?

    1. I can’t restore the phone !! :3 And after that I will flacher the phone will not cause problems on android! And finally Thanx <3
