[Q] Security problem on Lenovo s850 - Android Q&A, Help & Troubleshooting

Hello people,
I bought Lenovo s850, rooted, few days ago and now I have a problem. I had uninstalled some programs that comes with system that were irritating and now after I rebooted the phone there is a message SECURITY PROBLEM. What should I do to solve that?? Its a KitKat 4.4.2, VIBEUI 2.0.
THANK YOU

I have the same phone got it 2 days ago, but you mentioned that your phone is rooted, could you please post the link for rooting the Lenovo s850?
Once I can root it I will try to port CM to it, but I need to root it first.
Thanks.

There are 2 roms on needrom.com but the older one just causes a constant boot loop. The other one needs installing via cwm but I cant find any info on installing it. Anyone else seen any info?

Can anyone who has the s850 from china do a rom dump to needrom? My original rom was vibeui_v9.5_9422_3_st_s850 but now I have wrong version from lenovo forums.ru which removed imei's and messed with partitions and radios.

You just need to copy and paste below line into the build prop
ro.lenovo.check_safeapp=0
After this, save build prop and reboot your phone.

Hi, would you mind telling me how exactly to do that? I have just downloaded Build prop editor but I have never used it before and I am a little bit scared that I'll make everything even worse.
Concretely - should I just copy this line wherever in column of /system/build.prop? Doesn't matter where?
Your answer would help me so much.
