My brother has got a POCO F1 and, he wanted to format his userdata and cache partitions like me (Mi 6 user here, AEX Pie + Vantom Kernel) to F2FS on his POCO.
What I've tried (and succeeded) is, adding the lines from my fstab file to his fstab.
Here's the steps we've followed:
- We've installed 9.1.24 Global Developer fastboot firmware by using the MiFlashTool (because AEX 6.3's flashable zip gave an error and told us to update to that version in the output).
- Then we've installed OrangeFox 9.0.1 as it also supports F2FS.
- Then I've got that fstab file, added the 2 lines for userdata and cache into it for F2FS, from my fstab (same android versions and kind of identical partition tables like my Mi 6 so, we tried - and succeeded, please follow).
- Then we've formatted the userdata and cache partitions to F2FS in the recovery.
- Then we've flashed AEX 6.3, Sphinx Kernel (looks nice, I may get some ideas from that) and the flashable* (see the attachments, alongside the original fstab from that version) "FSTAB-EXT4&F2FS-encryptable=footer-BERYLLIUM.zip" that I've made for the fstab.
- Then the GApps (particularly, OpenGapps Nano variant) and the other stuff like fonts etc (not important to specify but meh).
Then the system booted just fine, we've tried everything we could imagine to test and it seems working totally fine.
* Because of I was just lazy (lol) and used that old ass ZipMe app to create the flashables below, before flashing them you have to mount Vendor partition from the Mount screen of the OrangeFox/TWRP to get the the new fstab file written successfully.
> Also note that because of the POCO lacks a proper encryption method on F2FS (just like my Mi 6) your userdata partition will remain unencrypted by using this fstab file.
> For any reasons if you'd want to have your original fstab file back (even though this new one would work just fine for default EXT4 too), you can use the other flashable that I've attached below.
I hope this would be helpful for anybody so sharing the steps and ideas.
I think the same idea could be applicable to the combinations of other kernels that support F2FS and (I don't know, if anybody tries it please tell in the comments) even for MIUI (with a kernel that supports both F2FS and MIUI of course).
If you have any questions or suggestions, (preferably) tell in the comments or if you really want, you can also send pm for various reasons.
I hope that support for F2FS gets improved over time so everybody gets to use it on their devices lol, it's the healthy decision for the flash based storages (check the up to date documentations before starting a flame war or I'll ignore your ignorance - I'm just trying to help here and I feel bad for having to state this here explicitly, on my own behalf).
Note that, I'm not responsible for any possible damages/data losses to your phone (you know the drill here at XDA)/thermonuclear war or whatever; so please use your own brain and make your preliminary research and take precautions before trying anything that you aren't familiar with. Thanks.
