I have this issue:
flashed 26.04 nightly and my phone start rebooting constantly (like a soft reboot). Then tried to flash last known working nightly 20.04, but gets fc (processes: media, phone, messaging, email & so on). Last backup is from January and don't want to restore it yet, because i'll loose too much data

What CM version is the 20th nightie - 12 or 12.1? If 12, you might want to flash also the appropriate GAPPS. That changes with Android 5.1, a.k.a. CM12.1.
Still it's strange 26th nightly works like a charm for me.

Have you tried using a different version of Odin?

So guys... After long search and many hours I have found my easy problem:):):). I have tried the whole time to flash from 4.4.2 to 4.3 because I dont know that i have updated my software. But downgrading isnt possible with samsungs new bootloader.

Last versions of CM12 aren't available for download.

tried IE and firefox.
CM12 last nightly not found on Cyanogenmod page.

I have the same problem, It's not a question of browser. The early versions of CM 12 are available and the new ones of CM 12.1 are also available.
Its only the latest versions of CM12 that have that problem.

    CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0.2 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.​

    #include <std_disclaimer.h>
     * Your warranty is now void.
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at us for messing up your device, we will laugh at you.

    CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

    We have de-unified the Galaxy S4 line. Too many issues with having them all in one and a maintainer's nightmare. Look for jfltexx builds now as opposed to the jflte builds you previously used.

    This is not the place to talk about custom kernels, don't report bugs/errors if you use one.

    I know that me and @alucard_24 work together on our custom ROM but this is official CM.

    Original Alucard kernel isn't updated with new stuff, this means broken sensors etc. Only Alucard in our CM custom builds is updated for now (we had to test it, that's why you still don't have an update available)

    GPE system size is being fixed in upcoming build

    Inviato dal mio GT-I9505
    For those having a greenish screen on latest nightly:
    Go to Settings -> Display & LED -> LiveDisplay -> Color calibration and set all sliders to about 50% (I have red=50%, green=47%, blue=51%)
    Then press OK, switch off the screen (power button) and switch on again -> voilà, natural colors!
    Till 1st lollipop snapshot is released :D:D
