Viper OS for Lenovo P1m is based on latest Android Nougat 7.1.2 with October security patch and is the most stable custom ROM so far ported to the device.
Unlike the previous custom ROM’s for Lenovo Vibe P1m, this ROM is so far the most stable and after usage, for 3 days we found out that this can be used as a daily driver. But the major issue has been fixed so far and that is the camera being green, I tried many third-party camera apps and they work for a while and then the same bug continues to appear in the previous ROM’s like AOSP Extended and CyanogenMod 14.1 which many users complained as well.
Viper OS for Lenovo P1m has been made more stable than any other custom firmware, you can download and flash it on your device to get better battery life and performance. There are lots of advanced features and modifications done and you can check it yourself after installing it on your device.
The ROM is unofficial so please do not expect nightly updates and it is is based on 64-bit CPU architecture, please download the gapps for ARM64 from the links provided below in the downloads section.

i am using the kernel 3.10.65+ and when i try to install this rom i stuck on bootloop, i have read that many users have successfully installed the new kernel 3.18.19 in vibe p1m. pls help me how can i do this.
Which version of TWRP are you using?
I have tried every available version of TWRP like 3.0, 3.1, 3.1.1 but not been able to install the kernel 3.18.19 . ALL the time there is a bootloop. I am trying this from the last 2 months without any success. Any help from your side would be highly appreciated. I would be really very very thankful if you can provide me the fix for this.
Thanks
There is a bug I would like to bring attention towards.
there is a problem in back camera that it can’t focus on written documents or when scaning QR or Barcode etc. Front camera is fine though.
Cant install OS. every time I flash, it says successful but ROM is not getting installed on Lenovo Vibe P1ma40.
Have you wiped the dalvik, cache, system, data and then flashed the files one by one?
problem was because of older version of twrp
