The latest official 3.2.2.0 can't mount data (tapping the data mount checkbox does nothing; stays unchecked). I formatted it, rebooted, confirmed data was mountable, then booted into AOSP 8.1. Once rebooting back into TWRP it can no longer mount data. Am I missing something?

Edit: Log message is:
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid argument)

It looks like TWRP cannot handle with filesystem partitions, so flashing not possible here.
I should have checked first. I'm sorry for that.

I tried flashing an ODM image but it didn't work. It said "Error: trying to flash image to filesystem". Was running version 3.2.3-2 published recently. Edit: actually I were still running 3.2.3-1. Updated to 3.2.3-2 and it worked without issues...

Hello. I need to backup all data from Xperia X (F5121).
I have unlocked bootloader, then I have installed twrp and try to backup all partitions. I booted twrp and checked boot, cache, recovery, system, vendor, data, oem, trim-area partitions (all checkboxes that was in backup section). After swiping to backup everything successed except oem partition on which it says Failed to mount '/oem' (Device or resource busy).
Can you help me how can /oem partition be backuped?

Stock?
OEM can only have a backup when you have one of sony's kernels delivered in .IMG flashed into OEM....so if you're on stock...OEM backup isn't necessary because you can't override stock kernel

How to install this? Do i need a pc? I just don't know sorry.
Yes..you need a PC


Mini tutorial

Place the recovery into the same folder that you have minimal adb and fastboot installed (there are thousands of tutorials I you haven't yet)
Rename it to something simple you can remember and type in this after double clicking a file called "Cmd-here.exe"

Adb reboot bootloader (turn on adb debugging and make sure bootloader is unlocked)

Fastboot flash recovery <Your simple file name here>.IMG

Done!

Updates can be installed trough twrp itself because sony handles stuff like that differently

Just download reboot to recovery

Install> install IMG> (search for update and tap on it)> tap recovery>swipe

Thanks. Yes it is stock. So, I even can't flash oem partition for example with flashboot or something? I thought that from twrp I can do everything what I want.

Basically yes but there is no REAL OEM in Sony's software that needs to be backed up...

Or a bit simpler

You don't need to download any virus infected OEM image of the stock ROM

If you still want to do it and it says like "device/resource busy" reboot mount OEM manually and then make a second backup of OEM itself

What are you talking about? OEM partition doesn't "override" the kernel, nor it's related to it. When you're on stock firmware, OEM partition will hold an EXT4 filesystem containing customization and apps from your operator or your country customization in the case of a carrier free device. When you're using custom ROMs, the OEM partition will hold the ODM image that you need to flash during the installation of the ROM, generally through fastboot flash oem <ODM image> or through TWRP itself on newer versions. Regardless of what is being stored there, TWRP should backup this partition just fine (at least it does on my phone)...
