      1. i also had the same problem. After i install superSU it would restart and get stuck. and i removed battery and go to recovery but it would go to stock recovery. I did try stupid things to try flash CMod rom, and SUperSU, but it showed signature error and same problem persisted. Finally mine is working and having cyanogenmod but still twrp is gone, i have only stock recovery. Though i am not sure how i got it to work but i did this thing. You see the problem is with the TWRP and the supersu here in this page.

        Before you try this please download the stock rom from Asus website.
        And dont keep anythhing else in your sd card. because my sdcard also got formateed with this.

        1 ) I searched in google for “SuperSU.zip latest” and download the latest one from someother site.
        2 ) And i searched in google for TWRP for “Asus Laser 550kl” and i found the url in a webpage called “zenfonehelps.net” .i downloaded the version “twrp-3.0.2-5-Z00L”.
        3 ) I connected phone to my laptop and opened ADB and typed “fastboot boot twrp-3.0.2-5-Z00L.img”.
        4 ) this TWRP version is different from the one in this webpage. So this one did not show any error when i first installed SUPERSU and then continued with CyanogenMOd from this page. And wipe cache and dalvik cache.
        5 ) And it restarted and i waited for 15 -20 seconds…voila… I can see the cyanogen mod logo…
        6 ). Though i have installed CMod, my recovery is back to stock rom and my sd card got formatted. And i want to change to TWRP.
        7) First i willl download the stock rom and try these in case i mess up something.

  10. Hi

    Your steps will NOT work on Marshmallow 6.0.1 version.
    Even the XDA sites are confirming that the latest Boot Unlocker will NOT work on Marshmallow 6.0.1.

  12. Hello buddy,

    Since you’ve updated this thread, you should’ve included the latest version of TWRP which is v3.0 I think. So can we flash the latest version instead of the version listed here? If so please update the thread again hosting the latest twrp update.

    Thanks.
