Sony XPERIA Z1 is
Sony Mobile flagship for 2013. This phone has large fullHD Triluminos
display, powerfull quadcore CPU from Qualcomm, 2 GB RAM or 20,7
megapixel camera. Sony XPERIA Z1 is also water resistance. Below you can
find the latest firmware for the phone and also three tutorials/manuals
- how to unlock the bootloader, how to relock the bootloader and how to
backup the original firmware customization.
First of all one important thing -
before you start to do anything with your phone, do the backup of your
personal data. It is only for your safety in case that something goes
wrong or any mistake happens. In that case you can use the backup to
restore the data and try to do everything once again. Each tutorial has
been done many times to verify its propriety, so just read carefully all
instructions and continue step by step. For each of Sony (Ericsson) XPERIA smartphones we will provide a manual consisting of 4, 5 or 6 „HOW TO“ chapters. Our
tutorials will be of course updated every time when Sony Mobile
publishes anything new, affecting any of our topics. All important files
have been stored on Google Drive, so there should be no problem with
downloading. The major part of every file has been created by myself and
every file has been tested on the corresponding phone. In this
guideline related to the Sony XPERIA Z Ultra you can find some photos
and videos showing how to proceed, but the most important thing are the
below written manuals. All referenced files are determined for Sony
XPERIA Z1 C6903. So, what can you expect in terms of mentioned manuals /
tutorials?
It is following 6 guidelines showing HOW TO:
1. how to install the newest Android 4.4.2 for your phone (for Sony XPERIA Z1 C6903 it is currently the 14.3.A.0.757 firmware)
2. how to install the newest Android 4.3 for your phone (for Sony XPERIA Z1 C6903 it is currently the 14.2.A.1.136 firmware)
3. how to install the newest Android 4.2.2 for your phone (for Sony XPERIA Z1 C6903 it is currently the 14.1.G.2.257 firmware)
4. how to backup your original firmware customization (it is important in case you must send your phone to service)
5. how to unlock the bootloader (in case you want to install the custom kernels with recovery menu and much more)
6. how to relock bootloader on your phone
1. how to install the newest Android 4.4.2 for Sony XPERIA Z1 C6903a) first of all, check your firmware version (if you already have the newest one, you do not need this tutorial)
b) download and install latest Flashtool from
here (mirrors
Google Drive or
Mega)
c) download also latest Android 4.4.2 (mirrors
Google Drive or
Mega) for Sony XPERIA Z1
d) paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool
e)
open the XPERIA Flashtool, click on flash and choose downloaded
firmware, than click ok. Important - if you do not want to delete any
data of your phone, just uncheck flashing userdata.sin file. All data
will remain in your phone, but sometimes it can cause additional
troubles. So it is better (and I recommend that) to do the backup of
your personal data, than proceed with clean instalation and then restore
your personal data.
f)
turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding volume down button
g) after few minutes all is done and your phone gets the new firmware
