[Q] Backup before 1st bootloader unlock and flashing

Hi everybody,
I'd like to ask what i have to backup before unlocking bootloader and flashing custom ROM.
I am Xperia-newbie so I rather ask before doing it. For eg. on Samsung Galaxy S was recommended to backup "EFS" folder and make ROM backup via CWM before flashing.
Is on Xperia SP something like "EFS" folder which I have to backup?
And can I somewhere download "original ROM" for Flashtool (Non-Branded GERMAN phone) if i want to revert my phone back to original (...warranty...).
Thanks for your replies...

Hi, before unlocking you need to backup TA here:

And if you want to revert back your phone to original you need to follow this tutorial:

How to backup current phone's firmware?

Hey, I was thinking before the big KK update to make a flashable backup of the current stock but rooted ROM that's on my XZR, locked BL. Any ideas? Aka the total backup, prerooted ftf. Any ideas?

First,downgrade your phone to 4.2.2 firmware & root it
Then install custom recovery & flash a pre-rooted 4.3 rom
Lastly make a nandroid backup using CWM recovery/TWRP etc...

Just take a nandroid backup via CWM before upgrading ,then when you decide to go back ,just flash the 4.2.2/4.1.2 FW using flashtool ,root it & install recovery ,then restore your nandroid backup

I think what the TS wanted was to backup his current firmware that's stock and rooted, before the upcoming KK update, so he can easily flash it back if he's unhappy with KK. I understand this sentiment because I held out for so long with 4.3. I recently updated to 4.4.4 (rather forced because my phone got stuck in a bootloop with no other way but to use Sony's PC Companion to fix it) but was unhappy with KK (some of my apps stopped working or worked inconsistently, and KK prevented apps from saving to the external sdcard) so I had to download the 4.3 ftf to be able to go back to 4.3. If I had backed-up my 4.3 then, I wouldn't have had to download a possibly different region's version of it. So now, prior to lollipop being rolled out for the ZR, I'm looking for a way to do just what the TS wanted to do. I hope somebody posted a guide somewhere here in xdadevelopers.

I also backup all my apps and settings with titanium backup

[Q] Recover the EFS Folder

Hi, so I decided to flash the lollipop OTA for XT1095 in a XT1097 I follow a guide that say that you have to backup the EFS folder and I did it, but after flashing the OTA the backup was missing, so now I don't have IMEI, I read somewhere that you can actually recover it but not the how.
Can anyone provide further assistance in this topic?
Thanks in advance

[Q] Unlock Bootloader and Restore Backup

Hi, m8s!
I'm using the official .283 ROM at the moment. I'm root and have CWM. I wonder if I make a backup of my current ROM and unlock my phone's bootloader (hence I lose all my data), could I restore the backup after without re-locking the bootloader? If yes, should I restore just /data or could I make a complete restore?
Thanks in advance!

anyone?

If you would make a backup of your current ROM, that doesn't backup your TA-Partition (I think), you need to make its backup seperately

How to upgrade firmware

Hi. I have unlocked bootloader, so i Lost ota update, and i don't do a TA backup.... So how can i upgrade firmware without reflash the whole software?

All I can think of is a backup of data partition if you have TWRP and then do a full system flash. Otherwise you could back-up your own personal information using other apps and then flash and then restore ( I do it this way ) as it's the easiest and I've never had any issues with personal data being lost.
