AT&T and Verizon users: since your bootloader is locked, you must be on the UCUAMDB or UCUAMDL bootloader if you own an AT&T phone, otherwise if Verizon you must be on the VRUAMDK bootloader in order to use this ROM. Do getprop ro.bootloader in Terminal Emulator or through ADB shell to find out which bootloader you have

Using F2FS
What it is? Wikipedia

To use it you should first convert your EXT4 partitions through recovery, before installing this ROM.

On PhilZ:

Wipe and format options->custom format options->toggle ext4 f2fs migration
Format cache->f2fs
Format data and data/media-> f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)

On TWRP:

Download and install this TWRP version: https://www.androidfilehost.com/?fid=24269982086988952
Wipe->advanced wipe
Select cache->change or repair file system->f2fs
Select data->change or repair file system->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)

Now you can install this ROM following installation steps in post above

Antares! Time for a Android 5.1 Updater?

knuckles1978 · Mar 28, 2015

Is the f2fs conversion a must for this, or can I leave my partitions ext4 and install?

Thanks AntaresOne

george stamatos · Mar 28, 2015

Thanks !!!! Could it boot with multiRom or none of the kernels could support it ? Thanks in advance

Thanks AntaresOne

You can also leave ext4, but with this ROM the system partition will be automatically converted to F2FS

You can boot with MultiROM, but leave the default kernel inside this ROM

In official 5.1 no. It should be fixed on some next release. BTW i know that exists a xposed module to fix it. In that thread i have read that on cm12 is useless because a patch for fixing memory leak has been already apllied. I don't know if it's already included in this rom

I just know that this problem is annoying as hell and very "intrusive", i.e. I see it all the time on my phone, every app which is closed for 5 minutes or so, sometimes even seconds, has to be reloaded...

But from what i have read, what are you saying it's not memory leak problem of android L. Memory leak is totally another thing

johnny88 · Mar 28, 2015

[JDCTeam][STABLE][5.1.1][26 January] Optimized CyanogenMod 12.1 builds [EOL]

Would you like to have an Optimized CM13 (Marshmallow) in the future?

Yes

No, I would like a JDCTeam's own AOSP-based ROM

No, I'd rather have AOSP 6.x
