[enderzip]

Have you ever experience slow down, lag or even freeze on your Nexus 7 2012? Well there is a solution to this problem by changing your files system to F2FS, this solution will not revive your old and dying flash memory but it will greatly improve performance on any ROM, especially Android 5.1. There is many methods on XDA like ParrotMod by parrotgeek1. But F2FS is a more well known method for this.
REQUIREMENTS
1. TWRP recovery installed.
2. A ROM that support F2FS (search Google for this).
3. A kernel that support F2FS (most likely will be included in the ROM).

1. REBOOT INTO TWRP (duh)
2. BACKUP YOUR FILES (optional)
Step 1: Press "Backup"
Step 2: Select System, Data and Boot.
Step 3: Swipe to Backup
Step 4: Wait...
Step 5: Copy the backup files to your PC (copy the BACKUPS folder)(/sdcard/TWRP/BACKUPS/)
Congratulation, you have successfully backup your device.
3. FORMAT TO F2FS (the fun part )
Step 1: Press "Wipe".

Step 2: Press "Advanced Wipe".

Step 3: Select the partition you want to format to F2FS. The ROM you choose might not support /system F2FS so you have to be careful. After that, press "Repair or Change File System".

Step 4: Select "Change File System".

Step 5: Press "F2FS".

Step 6: Swipe to Change.

Step 7: Wait...
Step 8: (optional) Copy your BACKUPS file to your device and select "Restore" on your TWRP home screen.
Step 9: (optional) Select the folder you just copy to your device.
Step 10: (optional) Select the partition you want to restore.
Step 11 (optional) Swipe to Restore.
After its done, you can reboot your device.
Congratualtion, you have successfully format your files system to F2FS.

Note: If you want to change your device back to EXT4, follow the step above, press "EXT4" instead of "F2FS" at Step 5.

Depend on the ROM you are using. I suggest you use the ParrotMod by parrotgeek (the link is in the post). F2FS need a compatible ROM to work, and sometimes will cause compatibility issues.
Yes, it will greatly improve your Nexus 7's eMMC performance.

You need to update your TWRP recovery to the lastest version. TWRP link: https://dl.twrp.me/grouper/
Select the lastest version (3.3.1-0) to download it. After that, just flash the .img file.

Well, it sounded good but everytime I convert to f2fs it has a boot screen asking me for the decrypt password and won't let me get past that, but when I convert back to ext4, no boot screen, ever deal with this? I only get the but screen in f2fsm

Try to boot it without restoring the backup.
