I had modified my system, such as build.prop and other sound mods, will it affect / broke ota installation?

Yep. It'll will broke the installation process, since you've modified the build prop and system, it'll surely give you error, so I'm requesting you to please roll back to stock build prop from here

Sprout4 / Sprout8 [These build.props are flashable zips now, so all you need to do is just flash them and then try installing ota it's gonna install without errors. And Uninstall if you've any sound mods installed, then attempt the installation, it's gonna update successfully! :D

Note=This method works with systemless as well as system mode root, you can flash this ota over custom kernel too.

I've xposed and Layers theme installed, how can I successfully install this OTA?

FYI, just Uninstall xposed framework & layers theme, then apply OTA, it's gonna install successfully!

How can i re-root my devices, after installation of ota zip?

Yes, just reboot after installation of Official ota, after a successful boot, again boot back into that twrp recovery, simply flash custom boot image [custom kernel] followed by Super su 2.50 zip, wipe dalvik/Art [IF YOU wish] reboot. Done!

Yo, I'm using Sprout4 Rom on my Sprout8, which ota should I flash?

Nothing to worry!

Just download Sprout4 ota and flash it.

Compatibility ?

Any Sprout4 OTA over Sprout4

Any sprout8 OTA over Sprout8

Yay! There are links for full stock Roms, how can I flash them?

Yep, those links / zips are full stock Roms, if you're running on any build or running on any custom rom & wanna revert back to full stock with September security patch, then just download those zips, reboot recovery, perform a full wipe [Twrp> wipe > advanced > wipe everything except Micro_SD]

Then install that full stock rom zip, hit reboot key after installation! :p
