First I have to apologize for being a noob, and if I am posting questions that has already been answered. I can't post these question in the original thread about F2FS file system, so I am posting this here.
I am currently running stock Android 4.4.4 on my Nexus 7 WiFi (2012), and because it has become very slow, I want to root, install Cyanogenmod and use F2FS file system.
I have used CWM-recovery and installed custom roms on a Huawei device before, so I have some experience with this. I have also some experience with Linux and using ADB. But I don't want to brick my Nexus 7, so I have some questions before I start:
I want to unlock the bootloader and install custom recovery. I want to avoid using toolkits, as I don't know what they installs on my Nexus 7. I found a tutorial here that I am using, but I am not 100% sure if I am following the correct steps?:
1. Install SDK and drivers
2. Enable Debug on the Nexus 7
3. Download CWM-recovery to the same directory as adb.exe on my PC running Windows 8.1
4. With CMD: run command "adb reboot bootloader" then run command "fastboot oem unlock" (I know this will delete all data on my Nexus 7)
5. After unlocking, flash CWM-recovery with the steps from the tutorial: run command "fastboot flash recovery recovery-clockwork-touch-220.127.116.11-grouper.img".
6. Permanent flash CWM-recovery: mount "/System" and rename/backup "recovery-from-boot.p" with the command "mv recovery-from-boot.p recovery-from-boot.bak" (Is this step necessary? I have seen other tutorials skipping this step.)
7. Backup everything from recovery, and move the backup from the Nexus 7 to my PC. (I don't know if this step is necessary, but I'll do it anyway)
Are these seven steps above correct, or am I missing something? If the steps above are correct, then can I now install CM11 Snapshot M7 with F2FS with these steps?:
1. Download and copy "CM11.zip", "gapps.zip" and "LegoKernel-F2FS-140228.zip" from PC to Nexus 7, then install them from CWM-recovery.
2. Download "recovery-F2FS-A.img" to the same directory as adb.exe
3. Reboot the Nexus 7 into Android(CM11), activate Debug, run command "adb reboot bootloader" then flash custom TWRP with the command "fastboot flash recovery recovery-F2FS-A.img"
4. Reboot into TWRP-recovery, go to Wipe menu and format data.
5. Reboot into Android(CM11)
Will these seven+five steps work, or am I missing something? I don't want to brick my Nexus 7, so if someone could verify that these steps is correct, that would be great.
And one more question: Can I change back to CWM-recovery without losing the F2FS file system, or should I just use TWRP?
