Flashing tutorial to Upgrade Xperia X10 to Latest R2BA020 firmware by Debranding
[ UPDATE ] : This upgrade tutorial doesn’t work any more as Sony Ericsson has updated their SEUS and won’t let you use the Replace File trick anymore! Will try to find another workaround and will let you know! Stay Tuned!
[ UPDATE 2 ] : This trick still might work for you. Look at a suggestion given by one of our readers and i guess you should try this trick for the tutorial to work for you. Here is a direct quote from what he said,
Martin : Do as you do in the tutorial (download files, rename them). When SEUS downloads the firmware files it downloads the 15+MB file first, so when you see the file has somewhere around that size replace it. When downloading of the 120+MB file is coming to an end move the unbranded firmware file into the blob_fs directory, but don’t hit “replace” in Windows explorer jut jet. Time it right when the download is complete.
And for any further queries please feel free to ask in the comments section!
I notice many of you are not able to upgrade your Xperia X10 as of yet as the Latest Update for Xperia X10 has not yet been rolled out in all the countries. And it’s only the Lucky Spanish people who are able to get the hands on the Latest Fimware update for Xperia X10-R2BA020.
So, i write a tutorial to upgrade your Xperia X10 to the Latest Firmware-R2BA020 by debranding your Xperia X10. But, before i do that, i must warn you that
Debranding or Flashing your Xperia X10 is a risky process and if not done correctly, it might brick your phone. So, read the instructions carefully before proceeding further and do ask me in the comments section, if you are unsure of any step in the tutorial. And Lastly, please take the responsibility of whatever you do to your Phone. You would be responsible for whatsoever you do to your phone.
The warning message is just for you to make extra cautious while flashing your phone. but, not to discourage you. Generally these things don’t happen but if done in-correctly you might brick your phone. So, to avoid that situation i’ve to write that warning.

I am Manish Kumar. A Tech enthusiast and a blogger. An android developer with basic knowledge about android platform! 
hello buddy..jst wonder,why in my blob_fs folder ,there’s no file with 120mb size?there’s only 15mb and 9mb only?
Hello, I am trying to update the firmware but when i did that and replaced the files with the downloaded ones but still cant update.
when i replace the files it again downloads the files and update from them,
I followed martins suggestion and replaced the 16 MB file first and then at the end of the download of the 120 MB file, i replaced the file and then it says “Update failed” and asks to retry when the battery is full.
Pls can you tell me the detailed instructions of how to update R2BA020 onto my x10
You need to be pretty quick to use martin’s suggestion! And you need not to use this tutorial if you have never de-branded your Xperia X10! Simply Update your Xperia X10 to the Latest Firmware R2BA023/R2BA026.
Can you explain martin’s suggestion a bit more. i didn’t fully understand it. Thanks.
I explained the trick to Downgrade your Xperia X10 to the Original Generic Firmware, here in this post,

Hi Manish,
may be this query is basic, but iam new for Android.
I got a new Sony Ericsson X10 with Android 1.6 in Singapore yesterday.
Is it possible to upgrade on our own the Android 1.6 to the new one ? If so how?
Thanks & regards,
Else what is the process of the same ? Hope the new Android OS is with advanced features / bug fixes…. Kindly guide me
Sami
You presently can not upgrade to Android 2.1 or above presently. But you can soon upgrade your Xperia X10 to Android 2.1!

Hi Manish,
I have a xperia x10 mini which has been brought from UAE and is being used here in India. There is no market app in the phone due to some regional regulations. Is there anyway to flash the firmware to get the market app in it? Any tutorials u can guide me to to help me get the market app? Any other suggestions? 
A total ANDROID Newbie here.
thanx in advance.
Vijay
You can probably try to De-brand it and flash it with a Custom Indian Firmware to get the Android Market on it! Or you can simply ask any Sony Ericsson Service Center here in India to do that for you. ( you might need to convince them that it can be done! )
Else you can follow the tutorial for Xperia X10, in the blog itself ( Use Search! ). But you need to get Generic X10 Mini Firmware files!
Hullo Manish,
Dude I think you are a genius, at least compared to me. I may sound a bit dense, but is this tutorial the same as “flashing” the phone?
What I am trying to do is get android market app ( which is not there on the phone because I bought an unlocked set ) and I heard some on forums saying that flashing will make me have it.
I have also just updated to v 2.1. Will doing the above downgrade/ affect the update ?
Thank you so much, you are a great help!
IF you have Android 2.1 on your phone, you can just root it and install the Android Market app on it, if there’s not one in your phone! Let me know if you want me to upload the Latest Android Market app for you!
hey…
i got my x10 mini pro from uae.. by default im not having android market and apps installer

Search the blog for tutorial to get Android 2.1 on your xperia X10 and that should enable android Market on your X10 as well.
Upgraded my rogers branded x10a from 1.6 android to nordic 2.1 x10i , is it possible to update my x10 using Sony Ericsson update service SEUS ? anyway ? Thanks.
Yes! But it will now update to X10i updates only for the nordic firmware!
Hi, I need some help here pls…. can you pls show me a link to upgrade my firmware version from 1.6 to 2.1? I also want to ask if i upgrading the firmware, will my warranty we void?
Because there’s a problem goes with my friend. when he already upgrading his version to 2.1 and downloading application don’t know what version could not open. And he said that maybe the company will help my friend to repair because the firmware had just change to 2.1.
Need help pls… I will appreciate it very much.
Updating to Android 2.1,Eclair won’t void your warranty. Use PC Companion / SEUS to update your phone to the latest version.
Hi there,
I would like to restore my phone to official android 2.1 version of my mobile. Am using Xperia X10i. Is it possible?
