xXx NoLimits the OxygenOS Stock ROM enhancement for OnePlus 6/6T
xXx NoLimits is not a Rom itself but it’s a Magisk Module which works exactly like all my previous Roms except that it does not include any OOS Rom components like Firmware, System, Vendor partitions or the Kernel. Therefore the size went down to about 200MB+. In combination with the OOS stock Rom it still provides you with all options you might have used already with my previous Rom versions.
As a Magisk Module running on top of the OOS stock rom, xXx NoLimits works 100% Systemless and provide you with plenty of options to be selectively installed. This way you get most of the typical things you usually have to collect and install one by one all out of the box.
