WARNING! This ROM is for the GT-S7275R/B/T variants only!

LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.1 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

Q/A thread:
Please use the above unless you have something development-related to contribute here. Thank you.

 * Your warranty is now void.
 * We are not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at us for messing up your device, we will laugh at you.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.


LOS-14.1 Install Guide

Note: LOS for Galaxy Ace 3 LTE is provided with no warranty. You are installing this software at your own risk. You may be violating your warranty.

Download LOS-14.1 and OpenGapps zips and put in /sdcard

Before you install LOS-14.1: Preparation (First three are optional. If you want to start fresh, these can be skipped)
  1. Install AppBak from Market, run it and save a list of all your apps.
  2. Install SMS Backup and Restore from Market, run it and backup your SMS history.
  3. Install Call Logs Backup and Restore from Market, run it and backup your call log history.
  4. Boot into TWRP recovery. Make a full backup. You will need this backup later if you decide to go back to your previous ROM and data.
WARNING: Many apps will Force Close LineageOS su addoncrash if you restore data from a previous ROM.

  1. Use TWRP Recovery from the attachments for now!!
    • Warning: Only use the recovery from the attachments to flash LAOS-14.1. Otherwise, you risk bricking your phone!
  2. Wipe system, data, dalvik and cache. (For clean installation)
  3. Flash lineage-14*.zip.
  4. Flash gapps*.zip.
  5. Reboot phone.
  6. After you setup your Google account, reinstall the three apps from Market in order to restore most of your apps, call log and SMS history.
  7. Warning: Do not restore backup data of system apps!
    • If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
    • It seems that restoring backups can also break Calendar sync.



LineageOS su addon
Upgrades from previous versions of LOS-14.1 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between LOS-14.1 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.

Whatever happened to asking for things instead off demanding 'em ? Our dev has been supporting our device for wel over 2 years now, camera zoom has'nt worked from the start. If he did'nt fix it 8 or 9 (maybe more, i kinda lost count) great ROM's later it might not be that simple. If you think it is maybe you could help him out a little and "fix it!!!" yourself.

special recovery?
Hi Kotzir!

First, thanks for your work, already using CM 13 for quite a while now, my only problem is the intermittent reboots. I was thinking of installing CM 14, what kept me away so far is the warning about the special recovery. Can you tell me more about this, or if it will change in the future?

The "special" recovery isn't special at all. It is just an updated TWRP for safe flashing of Nougat
