Ty for great job. I have a question. I have on phone a build of December 2018, I think the last offivial. The last taken by lineage downloader. Can I flash this new build on that old build? Is long time I'm not checking this thread, and is hard to read back many many pages.

A clean flash is required in your case.
Backup your data and wipe cache, dalvik, data and system.
Don't update your TWRP.
Use only pico open gapps (if needed).
Happy flashing !

Hello guys,

I have an old backup from December 2018 when official OTA updates of this ROM stopped.
No I'm on the current TWRP but restoring fails. Which TWRP do I need to restore this backup image?

Thanks for your help

It is a pity that a dirty flash not works.
Ended with a bootloop
Only a wipe of Data works. Restore Data works also not.
Always setting up the phone new with a new Build?

no problem for me, or always updated the rom without problems, use recovery, go to recovery advanced cleaning, Dalvik / ART Cache and Cache ... update RoM ... RESTART again in recovery ... again ... Dalvik / ART Cache and Cache, reboot into system

Hi @RamHa,

Is this the link you're after? Found it by following the above link, which goes to the fella's profile. Then selected S2, and up pops the build for today...

Thanks @Eric_Lev, for still supporting this old, but trusted device... :D

Cheers, Lister

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

    Root is not included by default on LineageOS 14.1. You need to install an add-on via recovery. You only need to install this once. You can download the SU add-on here
    After installation go to Settings>Developer Options>Root access and set to Apps only or Apps and ADB.

    LineageOS comes with LineageOS Recovery by default, if you don't like it (like me ;)) you can flash alternative recoveries using IsoRec. You really need 1GB /system partition. The smallest build-configuration is larger than 512mb. You can use ODIN, but you can also use Lanchon's REPIT.

    If you're interested in BLN, check this thread for a complete support of this feature.

    Hi all,

    :D I'm just dropping an image and a link :D
    Click here!
    Hi there you all diehard S2 users,

    As a few of you all users know, last couple months I'm working and testing PegasusQ-governor with a new PowerHAL. I'm planning to make this the default governor instead of on-demand to get same performance and better battery life. I resolved the issue PegasusQ with the 150Mhz fix of zeitferne so it is stable to use.

    What does the new PowerHAL?
    Currently the PowerHAL does this:
    • Powersave : conservative governor
    • Balanced: On-demand governor
    • Performance: performance governor

    The new PowerHAL supports PegasusQ governor by tweaking its settings (like its big brother i9300 does):
    • Powersave : PegasusQ freq limited to 600Mhz
    • Balanced: PegasusQ freq standard profile
    • Performance: PegasusQ fixed freq 1200Mhz (still drops to 800Mhz when CPU is getting hot. This is by-design and not managed by governor)
    Also we will have PegasusQ boosting:
    • Frequency will be boosted for 2 secs when an app launches
    • Frequency will be shortly boosted when interacting with the device for more responsiveness
    • Less aggressive profile when the display is turned off to save battery (using max 1 cpu max 600Mhz in PowerSave)

    I'm planning to submit the following commits in next weekly, but I want to notify you all first about these changes:

    What I like to know is if PegasusQ is really improving battery and/or performance when we set it to default governor.
    It must be set to default governor (at boot) because of the permissions which needs to be set at boottime.
    Otherwise the PowerHAL doesn't have permissions to tweak PegasusQ and we miss all the nice features.
    When the experience with PegasusQ is poor, I will revert the commits so we switch back to on-demand.

    • For those who wants to test PegasusQ + new PowerHAL right now, download my unofficial build here: https://www.androidfilehost.com/?fid=889764386195918750
    • For those who wants to test performance with Official build: Keep track of your battery life until next weekly and compare after you updated officially
    • For those who don't want take any risk with PegasusQ until tested: Don't update your phone at least 2 weeks

    In my case I got about 10% more battery life and PowerSave now actually saves power. However Antutu Benchmark maxed out at about 18100 (instead of 19500 with ondemand).
    I hope this will be the also the case on your devices.
    @the.gangster: I think it can just put LineageOS recovery two times, and since it is an option it can be disabled by the user.
    And maybe it can be extended to auto-flash it when the phone come from a not-IsoRec kernel but it is just my opinion.

    They have removed us: https://review.lineageos.org/#/c/161752/
    I hope someone fix sepolicies before the next nightly build raid.
    It is already fixed. The faulty commit is reverted and I requested to add our device again. https://review.lineageos.org/#/c/162099/
