Flashtool file AKA FTF is for flashing with flastool you can only flash signed zips in CWM

After hours of research I came to a conclusion that CWM is the problem. It is described somewhere in the thread about it. There is a better CWM but requires unlocked bootloader.

So I will ask, has someone managed to follow this tutorial, and has locked bootloader? If yes, could you link to the root/CWM thread or file that you used?

You didnt understand. I've flashed .18 then rooted it and after that i've installed cwm . I already have jb root.zib and super user on my memory card . Well, when i restart into cwm and select install from sd card/ choose zip from sd card it show me a mesage that says " no files found " ! And i;ve tried this metod many times even with .28

I have the exact same problem as poster above! It seems like CWM is not working properly, what exact version (link us) of CWM did everybody who got it working use?

Which version of CWM actually lets you choose install zip from sdcard and not give error?

I have CWM from that thread aswell, 6.1 for J. I can get into it no problem, but when I select choose zip from sdcard it says no files. I have put both files (superuser and jb root.zip) on:
- internal /sdcard/
- external sdcard

No matter what I do I get no files when choosing install zip from sdcard. Tried this on ST26i_11.0.A.3.28 and ST26i_11.0.A.7.5 makes no difference.

Do you have any idea what is causing this?

    For this, I wanted to ask at the experts, what it means "clean install"? :confused:

    Ok, all the steps I did and worked:
    1- I was in 11.0.A.7.8 branded Vodafone;
    2- Flashed 11.0.A.7.5 CE (unbranded) with flastool without wipping data;
    3- Rooted with UnlockRoot;
    4- Update over the air to 11.2.A.0.21;
    5- Reinstalled Superuser from the Play Store.
