Any way to get full image backup of Android XperiaX before I go to SailfishX ?

I bought an Xperia X, with android 6.0.1. I took backup of TA (DRM keys) - even I am not sure how could I put them back if I ever want to send the device for service.

Is there any way that I can take a full image backup of the phone ? Like dd or something ? The phone comes with slightly custom ROM, from a mobile operator, but hopefully it has unlock-able boot loader. I didn't unlocked it yet.

And if there is a way, how could I use it again in case it needed ?

Any ideas / opinions appreciated. This is the last thing I would like to know before I flash Sailfish X - hopefully in few hours.

I would suggest at earliest opportunity that you check bootloader can be unlocked - Dial ##7378423## and go to Service info » Configuration » Rooting status and check if Bootloader unlock status is Yes or No

The code for dialing is: *#*#7378423#*#* . Rooting status: Bootloader unlock allowed: Yes. The question is about backup - I have already checked that I can unlock the bootloader.

Thanks for pointing out copy/paste error, presumably you have already recorded your "Customisation Version" to be found in Service Menu > Software info? Suggest that you install Xperifirm - Xperia Firmware Downloader and see if you can find this variant to keep safe somewhere.

Thanks, I just downloaded and run Xperia Firmware Downloader. I put it to download a firmware, which is more recent than mine. Even I suppose it is kind of solution, still it is not the firmware I have on the phone. Any ideas how to get the firmware from my own phone?

@nas you should only care about making backup of TA to have DRM keys. Everything else is useless as you can get it form sony servers. In this post you should get all the info.

@lolek Good point. It boils down to really what @nas is trying to achieve. Making backup of TA and DRM keys is one thing for sure. Making backup of the whole Android partition may be overkill (but it would be simple and complete), but as Sony indeed provides ways for reflashing the device back to Android, wouldn't your usual user data backup (perhaps with the list of installed applications - oh wait, Google account actually holds this information) suffice?

I also have this question. I have read the topic about backing up the TA partition and I know I can reflash firmware using Sony's tool, however, does this bring back all the same version numbers in the Software Info panel of the service menu. Does that really matter? E.g. S1 boot, ETS, etc. as shown in this image (not my phone, or even an X, I just provide it as an example I found online).
