[Sony Xperia ZR] hagar006:
F2FS improves the benchmark score in most (if not all) devices by around 20%..

For testing:

I have modified an APK containing Aroma Installer to flash recoveries to fotakernel for our ZR's. This is an initial release..

It contains 2 recoveries.

PhilZ Touch and TWRP with f2fs (TWRP) support which has been tested and working in both Resurrection and Validus builds/ports and should work in all cm11 and CM12/CM12.1 with f2fs working in cm12 after march this year

Install the apk and flash either Philz or Twrp through the app in the drawer..

And no, this is not Xperia Recovery manager.

The recoveries are both contained in the app so making it 22MB to download.

The TWRP 2.8.7.0 has new graphics and f2fs support

PhilZ is stock 6.57.9 cwm v6.0.5.1 shared by [MENTION=4845837]uncomment[/MENTION]

Place the recovery.img (it is named twrp.img when you download but rename to recovery.img):) to you internal storage and use adb or emulator (download Android Terminal Emulator free from Store) commands to install to your Fota:

su (enter and grant root access if using Emulator)

dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel (enter)

If you use Xperia Recovery Manager app by [MENTION=4308696]championswimmer[/MENTION], rename the recovery.img to twrp.img and put in the TWRPXperia folder on your sd-card and flash to Fota through the app. Confirmed working.

If the image doesn't install correctly, please flash this hack:

Only cache and data/ ext-sdcard is convertible for now, if you try to convert system, you will brick your phone..

Use the following method to convert:

Convert to f2fs by pressing Wipe > Advanced Wipe > select the desired partition > Repair or change filesystem > Change filesystem > f2fs

Some added info by [MENTION=4929354]nostupidthing[/MENTION]

with f2fs twrp installed, i've changed /cache and /data into f2fs without wiping. you just have to backup /data, then format it as f2fs, click "use rm-rf instead for format" in twrp settings, then restore /data.

If any one is looking for a theme for twrp recovery, i found an excellent theme here: http://xdaforums.com/android/themes/theme-twrp-materialised-dark-light-play-t2915584

(Download resolution 720x1280 for ZR)

As an added service I am willing to personalize the splash screen at recovery start-up should you have any request ie your name, flag etc but i will insist that "TeamWin" will be present somewhere on your personalized splash.. After all, we all benefit from their hard work.. Do not expect your request to be done within the hour but periodically check and i will upload and link as and when you request is done..
