So how do I flash the new .28 build over what I have on my phone without losing any data? Use Flashtool or just through Recovery??
[Xperia Z3 Compact General] degraaff:
Yes, if you uncheck "DATA" under "Wipe:", then it'll keep your data I believe. But backing up what you want to keep and then flashing clean is the better way to go I think.

Can you explain for all of us how exactly (step by step) to download files with Flashtool and how to preroot it?

Thanks in advance! :good:
[Xperia Z3 Compact General] vcdwelt:
The whole thing is explained many times here in Forum, just use the search function and read trough some threads for details...

Short:

Needed Tools:

- Flashtool: http://www.flashtool.net/index.php

- PRF Creator: http://xdaforums.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904

- SuperSU: https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

- XZDR Dual Recovery (Z3C-lockeddualrecovery2.8.15-RELEASE.flashable.zip): http://nut.xperia-files.com/

- Start Flash Tool

- Open "Devices" -> "Check Updates"

- Select your device e.g. D58XX

- Double Click the Firmware you want

- Now Flashtool is downloading and reworking all for you, at the end you have an comnplete ftf file in C:\Users\USERNAME\.flashTool\firmwares\

- Start PRF Creator

- Select FTF, SuperSU and XZDR Recovery File

- If you want you can include flashable zips also e.g. xposed or others

- under Include select all 4 checkboxes and Sign zip (works also without sign zip)

- Press Create and wait until finished.

- Now you have a pre-rooted, flashable Zip File, which you can flash trough your recovery.

Maybe if i find the time i will create a complete tutorial with pictures, but can not promise this ;)

Uploading my pre-rooted ce1 right now ~45min.
[Xperia Z3 Compact General] krisu253:
Well to me it looks smoother and works a little bit quicker although I didn't see any changes in antutu benchmark. And of course the close all button which for me is a "must be". So basically yeah it is an improvement worth installing

If you want a cm rom or any other aosp, buy a nexus or a oneplus one, because there's not a great development for Sony devices... You have to fight with big issues every day and you lose the will to enjoy the rom actually...

Excuse my ignorance.. Just came from a Nexus 5 so I have no clue about Sony firmware.

Can anyone tell me what potential differences there would be between "Unbranded - Netherlands (1288-5414)" and for instance "Unbranded - CE1 [Central Europe] (1288-7915)" apart from the CE1 getting updates faster..

I mean, there must surely be differences between them else it would make no sense to release different firmwares. I'm slightly reluctant to flash my device without know the differences. My device is on 1288-5414 but I understand I can convert it to 1288-7915 without any problems to get updates faster.

I've looked around but I can't really find anything and I'd very much like to know the differences.

Hiya, thanks for the reply. I've read through that topic but I've not found any details on potential differences between the regions. I'm interested in what would change if I flash CE1 instead of Netherlands that came with the phone. Things like:

- Modem stuff tailored for NL you might loose

- Included apps/bloatware

- Preconfigured APN's maybe?

I'm assuming there must be some things tailored for the Netherlands, else it would make no sense to release it seperately from let's say a CE1?

I got the notification few minutes ago. I am running 23.1.A.1.28. I ran/installed the update and not much happened. The phone rebooted, the green droid (the one that appears while upgrading the firmware) worked for a second then the Sony PlayStation animation started. It looks like not much was upgraded. My version is still 23.1.A.1.28 after this. Maybe they are preparing the grounds for 5.1 ?

This is a Canada phone, not rooted and bootloader still locked.

US update for me as well. I'm guessing kernel bug fixes.

So according to XperiFerm, 23.1.A.1.28 has 2 minor versions, R4C and R5C. Flashtool said my Z3c was at R4C., and I manually upgraded to R5C.
