[ZTE nubia Z5s mini] malware and failed ROM & need pan.baidu roms

Hi, somehow i managed to get malware on my z5s mini and it kept turning on 3g and wifi and installing random apps and had adds popping up every few minutes.
So i did a hard reset and soft reset and it was gone for 1hour and then it came back.
I didnt have it in safemode.

Now i tried to install the same rom over using the standard system recovery.
I used this one: needrom.com/download/nubia-z5s-mini-kk/#comments
In the comments they say you dont need cwm or anything so i tried and got these logs:
[log]
-- Install /ext_sdcard ...
Finding update package...
Verifying update package...
Installing update...
Warning: No file_contexts
set_metadata_recursice: some changes failed
installation aborted.
[/log]

Since then i cant boot up my phone it goes to the splashscreen and after a while automatically in the system recovery.
Appearanty it cant handle kitkat roms so i need roms before kitkat.

The only thing that seems possible is that i use the standard recovery to flash a standard rom. But they are located on pan.baidu site so i cant download them(you need chinese number).
Does someone has them or can download them and post a link?
here is official link: nubia.cn/service.php?sid=5 (click the Z5smini without chinese characters)
i think i need the Z5Smini V0.20, Z5Smini V0.22 or Z5Smini V1.20 (4.2 to 4.4)
