I9505ZHUENB2 bootloader and NON-HLOS.bin work with all 4.3 stock rom
They are the only ones fully compatible with 4.4.2 and sound work
but if you want a stock kernel you need to use " I9505_stock_nb2.zip" for a working wifi
and change in build.prop the string "ro.securestorage.support=true" to "ro.securestorage.support=false"

build.prop ?? where can find it ??


build.prop is in system folder
you can edit with root explorer or similar but with a rooted rom

Today this downgrade is useful with same firmware like i9505XXUGNH7 not working with towelroot v3

So you can downgrade, root and update again with mobile odin without loose root and keepeng knox 0x0

Thanks for the downgrade. Everything is working fine except everytime I reboot the phone the phone forget the wifi password and I have to re-enter it everytime it reboots. Is there anyway to fix this?

Step by Step
Hi everyone! First of all: Thank you for your great work!

I went from cm11 back to stock 4.4.2 touchwiz on my S4 LTE GT-I9505 (Switzerland, AUT) yesterday. Now I would like to downgrade to 4.3, because I have issues with kitkat which remain (i.e. very bad battery life, and the sd-card problem).

Could anyone of you please give mive a step by step how to which is up to date?? I would really appreciate that, because I'm not so familiar with flashing etc, and I don't want to brick my phone (I'm a student...I just want a good working phone...-.-). And would I have to do a full backup inc system data (I actually don't know how to do this properly with TB and how to restore in worst case...)? Will OTA be available after flashing?

Every help is highly appreciated!! Thx in advance!

Someone help me:

I have a GT-I9505 GALAXY S4 LTE, android 4.4.2, product code ZTO, pda I9505VJUGNI2, csc I9505ZTOGNI2 and modem I9505VJUGNI2.

Is there anything I can do to root my phone keeping knox 0x0?

I want to upgrade to newer versions later, also keeping knox 0x0.
