Galaxy S3 LTE CM13 Marshmallow Custom ROM is brought to you by developer Winxuser and p.a.n. In addition to this ROM we also have the Lineage 14.1 for Galaxy S3 LTE (i9305) and we also have the Android Nougat 7.0 CyanogenMod 14/CM14 for Galaxy S3 LTE (i9305). If you want some more Lineage OS ROMs then stay tuned to the Lineage OS 14.1 ROM Devices list page. I have got another build which is brought to you by developer limjh16. These are the latest builds from all of the developers with lots of bug fixes and improved stability. Current status of both the ROMs are UNKNOWN and hence I always recommend to have a NANDROID backup using a recovery such as TWRP or any other of your lovely current ROM so that you can roll back if you are unsatisfied of this ROM. For more CM13 ROM updates and OFFICIAL update of Galaxy S3 LTE CM13, you can have a look on the big CyanogenMod 13 devices list.
DISCLAIMER:
Installing custom ROM requires a custom recovery to be installed on your device, which may VOID your warranty and may delete all your data. Before proceeding further you may consider backup your all data. You are the only person doing changes to your phone and I cannot be held responsible for the mistakes done by you. Neither the developer nor we will be held responsible for any disaster that happens to your device.
KNOWN ISSUES:
