1. how to install the newest Android 2.3.3 for Sony Ericsson XPERIA X10
a) first of all, check your firmware version (if you already hawe the newest one, you do not need this tutorial)
b) download and install latest Flashtool from Google Drive,
c) download also latest Android 2.3.3  for Sony Ericsson XPERIA X10
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 back button 
g) after few minutes all is done and your phone gets the new firmware












4. how to backup your original firmware customization
a) if you do not want to lose warranty of your phone, first thing you have to do is to backup your original customization

b) download Sony PC Companion and connect your phone
c) select update your phone in Sony PC Companion

d) application will prompt you to disconnect your phone before starting downloading firmware, just make it (remember – dont disconnect your phone when update just start…)

e) after finish downloading firmware cancel the update

F) after that, go to C:ProgramDataSony MobileUpdate Enginedbsome numberblob_fs, there you find 3 (maybe 4) files, which names start FILE
download and install latest Flashtool from Google Drive,
h) paste the three files, which names start FILE, from blob_fs folder to folder „Firmware“ included in the XPERIA Flashtool
i) open the Flashtool, click on Advanced, choose decrypt files and put all three files from blob_fs folder to the right columm
j) click ok and after approx. one minute a pop up Window will appear via Flashtool
k) mark all files except simlock.ta and transfer them to the right column, than fill in a box in the right upper corner (fill in what you want, it is just for you)
