Hey guys
I made a mistake and wiped the internal storage of a Moto G.
I already dumped the userdata partition to an image file but I fail to find an application that says it supports F2FS.
Do you know any apps I could use?
Thanks
I'm currently on AOSPExtended ROM(7.1.1) with it's stock kernel. I recently heard about f2fs system which is more faster and has increased life span of flash storage than current ext4 system.
Now I want to know whether this ROM and kernel are f2fs compatible, and how can I change my partitions to f2fs in detail without loosing my current data.
Thank you.
in previous iterations of android, only data partition was allowed to be in F2FS format (by default data partition is in F2FS format unless you have a GPE device). all the rest should be in ext4. some kernels allow cache to be in F2FS thats all. you can format some partitions to F2FS via TWRP recovery. however if any F2FS partition is unsupported you will endup in a bootloop.
I own a Motorola DROID TURBO (XT1254) with unlocked bootloader and the Stock ROM /data and /cache partitions are in f2fs filesystem and /system is in ext4 filesystem and I have some doubts and questions:
1. Some Custom ROM's like LineageOS on this device can be installed with /data and /cache partitions formatted in ext4 and f2fs, In your daily Stock or Custom ROM in which filesystem are formated the /data, /cache and /system partitions?
2. I read that the f2fs filesystem are used by Motorola on Stock ROM's due to notable higher write speeds (this helped to the Nexus 7 2012 owners, because has eMMC bug) but has more chances of data corruption (in some devices exists the garbage collection problem), and ext4 is more reliable for data and has higher read speeds. What are you experience with ex4 and f2fs filesystems on Android? and in Moto Maxx/DROID TURBO, which is better for you?
3. Apart for Motorola, Samsung create the f2fs filesystem but not use it in their devices, Huawei uses f2fs filesystem since Android 7.0 Nougat/EMUI 5.0, OnePlus tried it on OnePlus 3/3T, but in OnePlus 5/5T switched back to ext4. Google says "F2FS isn’t supported for the internal storage as it doesn’t support inline hardware encryption", and Android 7.0 Nougat and higher supports Direct Boot and file-based encryption but only in ext4 filesystem. A website says that the Motorola Moto Z (an other Motorola device) are faster than Google Pixel (XL?), because the Moto Z uses f2fs filesystem.
4. It would be good to share the used filesystem in your phone and in which ROM uses this filesystem.
Note: Can you check partitions filesystem with Diskinfo app or TWRP in Wipe> Choose partition> Repair or change filesystem
This information and questions apply for all Moto Maxx/DROID TURBO owners (XT1225, XT1250, XT1254)
I like to know your opinions about the ext4 and f2fs filesystems for Moto Maxx/DROID TURBO
In case of necessity, I post it also in DROID TURBO sub-forum

This was very hotly debated three years ago, in late 2014 and early 2015 -- mostly dealing with the XT1225. You can probably dig up old threads over in the Droid Turbo forum where it was discussed. (We were all in one forum back then. It was the "All Quark" forum.) The forums were split in September 2015, but some of the threads never got moved. Droid Turbo finally got bootloader unlock in November 2015, thanks to Sunshine, but by then the topic was no longer being discussed.
There was some reason why the topic was dropped and everyone just went with the default system. Maybe didn't work well with TWRP backups or something about encrypting? Also, there was false low storage warnings. I don't remember. I just remember it was too much hassle so everyone didn't bother.

The DROID TURBO I own have unlocked bootloader thanks to Sunshine (is a little expensive, but is worth it), I asking about ext4 or f2fs as filesystem for /data partition, the DROID TURBO Stock ROM is the /data partition formatted as f2fs, but the majority of Android devices the /data partition is formatted as ext4 and some questions and comparation between both filesystems for /data partition
Three questions: ¿The /data partition of your phone is formatted now as ext4 or f2fs?, ¿The encryption is working on both filesystems or only one (ext4 or f2fs)? and ¿Your phone is in the Stock ROM formatted the /data partition as ext4 or f2fs?

I don't use encryption on mine or my wife's phone. My phone is formatted however TWRP formatted it. @bhb27 our official TWRP dev and who maintains two popular ROMs recommends f2fs.
[RECOVERY][OFFICIAL TWRP 3.1.1][For all Quark][Moto Maxx/Turbo and Droid Turbo]
https://forum.xda-developers.com/showpost.php?p=62363432&postcount=2
[QUOTE @bhb27]The format of data partition is different, in 4.4.4 is ext4 and 5.x.x is f2fs.
I have restore more then 100 times in my test, in some i end-up in a "bad/bug ROM" and it happens when flash 4.4.4 over 5.0.2 or vice versa, in the most bad one the device lost response of the touch screen even in the recovery, the bug was simply resolved by restoring to stock via fastboot using files from a stock XML rom. In others bug's android boot after boot i try to unlock to use and it reset, and stay in that loop, boot try to unlock reset, i try to wipe everything but system and did not work, in all those case partition format of data was wrong.
TWRP will backup the partition exactly how it is, If the backup is EXT4 and the Data partition of the device is f2fs TWRP will restore the data and will not change the format.
That may cause a problem, so when restoring to a different OS version advanced wipe the partition and change the format.
To do that click Wipe>advanced Wipe> select Data> click on Repair or change File System>change File System>
For Kitkat android 4.4.4 choose EXT4
For lollipop android 5.x.x choose F2FS

This will not affect custom ROM, but i recommend to use f2fs.[/QUOTE]
In conclusion /data formatted as f2fs is better for Moto Maxx/DROID TURBO than ext4. I asking because only some Android devices use /data partition as f2fs because the majority is formatted as ext4. In Nougat custom ROM'S is f2fs better? And ChazzMatt your phone is formatted the /data partition as f2fs or ext4?
Is it possible to do this on devices launched with Android 9+ (using FBE by default) by modifying the userdata entry in fstab or similar, or have the current ROMs / kernels lost support to boot with this type of encryption? Are there any successful cases? I ask this because FBE is a nuisance for anyone who likes to modify their device. You need to format the userdata every time you change the ROM, consequently also losing the internal storage, different from how it was in FDE that just wiping data was enough. I have also had many problems at the device random not being able to unlock the userdata and forcing me to format it, which never happened when I had a device with FDE. Any help or information is welcome, thank you!
factory reset should do just fine, else try wiping the header / footer of the partition and format to ext4 or f2fs
Hello All,
Recently i applied local update on my one plus 8t and it wiped all my data everything is lost. Backup to drive and oneplus cloud was also NOT turned ON.
Any way to recover files ? I already tried Wondershare and few other applications but none of them worked.
One of my friend suggested RECUVA but its not showing my phone as a drive.
Please help.
May be an authorized service center has the means to recover the wiped data, means the forensic software needed. In any case, phone's Android must be rooted.
Don't trust the 3rd-party-softwares you've to pay for: are all more or less only crap.
Thanks for replying but can i mount my android as a drive (removable storage). just like flash drive.
it's pointless. FDE crypto-footer is garbage even if just a single byte is overwritten. FBE encryption keys aren't stored in userspace at all. your device uses both FBE + FDE. userdata partition is F2FS file system, no recovery tools will work. your data is unrecoverable per design
How to recover a deleted file from /data partition?
I factory reset my rooted Android M phone but now I realize that there was a file in the /data directory which I need. Is it possible to create an image (.img or something similar) of the /data

so data on my samsung j4+ which was factory resetted (because i had to unlock the boot loader) cannot be recovered?
I was talking about OnePlus 8T. That's different from yours
