Sony Ericsson Xperia X10 :: Downgrade The Firmware
Apr 3, 2010
I experienced no problems with the installed firmware (versjon 14) with my X10, but I read on a forum that some people had gotten their device a bit faster and smoother after installing the update that is available (version 16). I installed the update and now I regret and wish I never would have done it.
Now I have the problem with the "a" butten. When I hit the "a" button, I just get that the button was pushed and nothing happens in the textfield, so I have to push the "a" button twice to get something.
I couldn't find my wireless internett that was turned on, and in some of the programs when I write, nothing shows up in the textfield, but I can see that the text registered by the device because I can see the wordexamples coming up as I write. I wonder if there is a way to downgrade to the preinstalled firmware?

Some people keep asking how to downgrade back to 1.6. So I wanted to provide how to do it
Note: This will give you UK Generic R1FA016 firmware
1) Install SEUS (Sony Ericsson Update Service).
You can get it from here: http://www.sonyericsson.com/cws/down...-2.10.6.21.exe
2) Run SEUS, follow the prompts. You don't need to update the phone through it, but get the phone ready for updating. This process should install the drivers necessary for the rooting process.
Note: I suggest you keep your USB cable attached to that USB port. Remember which USB port of your computer it's attached to, as changing USB ports can lead to a bit of confusion for the next 2 steps!
3) To check if #2 was successful, click on Start, click Run, and type: regedit
In the Registry Editor that pops up, click on Computer, press CTRL+F, and search for this: USBVid_0fce&Pid_adde
After it's finished finding, on the right side you'll see DeviceInstance, then it says REG_SZ, then it says something like USBVid_0fce&Pid_adde5&270d2a78&0&3 You'll need that last bit (in this example: 5&270d2a78&0&3 Yours would probably be different). This is your DeviceID (you'll need it soon!)
Note: You may have multiple of these if you plugged the USB cord into many USB ports on your computer. Each USB port will give a different DeviceID, so if you have more than one DeviceID, you'll have to choose one, and if it doesn't work (you'll find out when you reach #5!) you will have to choose another one.
Alternatively, download the file in the next step and extract it, go to the folder called 1st, and run the DeviceID.jar file. It should give your DeviceID
4) Download this:
Download R1FA16 rar
or from here: [url]
Extract it.
In the step1 folder, you'll see a file called DeviceID.txt Open it up, delete whatever's there, and put YOUR DeviceID (that you found from the previous step). Save the file and close notepad.
Note: Make sure there are no extra spaces or lines after/before the DeviceID. The ONLY thing that should be in the file is your DeviceID, NO SPACES/LINES (for example, only this: 5&270d2a78&0&3 [yours will probably be different])
5) Take out the USB cable from your phone (leave it plugged into your computer) Turn your phone OFF. Open up step1.cmd (it's not inside the step1 folder, but outside it), but DON'T PRESS ANYTHING
Now we have to put the phone into flash mode. This is how you do it:
Hold the Back button on your phone, and while holding the back button, insert the USB cable into the phone. A green light should come on the phone (like when it's charging or a missed call) Quickly "Press any key to continue..." in the open step1.cmd window.
Let it finish what it's doing. It will say "Press any key to continue..." after it's finished. Until then, DON'T touch anything!
If you get problems in this step, refer to this post:[url]
Here's a helpful video for common java issue: [ROOT/De-Brick Guide] Java Issue 64 bit Fix Walkthrough (Video guide included) - xda-developers
After completion, this will give you a Generic X10i R1FA016 firmware (check it by pressing the left button, go to settings>about phone and at the very bottom under build number)
Keep your phone plugged into the USB.
6) Run SEUS to get to the latest firmware (do this before 2.1 is released in the UK if you don't want 2.1)

Does anyone have a link to the uk 2.1 firmware?I've tried this method Newbies Guide to Rooting X10 and giving you the newest firmware! - xda-developers but I get the java error and I can't find another DeviceID even after uninstalling all the SE software and retrying it all so I was going to flash using this method x10 Flash 2.1 Final + Global World Firmware 2.1 - xda-developers but I'd rather put on the uk firmware than the global one

Simple question - I've got an update via SUES this week and there's a small fault with it (a library file is showing up in the app list). Is there any way I can report this to SE? I don't really want to mail the SE Answers team, but at the moment this looks like the only route.

I have an X10 Mini unbranded, bought in Brazil, having the model number E10a, as I guess everyone in America continent has.
My question is: why do Europe get so many firmware updates and we just stay still? I'm saying that because as I was reading many forums about X10 Mini, I constantly seeing firmware updates, maybe I'm wrong, and the FW numbers differs from E10a and E10i.
So, my question is, FW 1.2.A.1.174 for the E10i is the same as 1.1.A.0.9 for the E10a? If they're both the same, no problem, but I don't think they're the same.

Just a simple question.

I have re-installed the app but the problem still persists. Does anyone know how to resolve this issue?

I bought an X10i a few months ago and I was installing PC Companion on my mothers PC when it told me there was an update to the firmware. When I came home on my own PC it told me I was up to date. I uninstalled companion and reinstalled it and was told of the update. When I try to update it goes through the first 2 steps and then tells me to unplug the USB cable from both the PC and Phone, make sure it is charged to 50%, turn off the phone for 5 seconds and plug it back into the PC and while holding the back button plug the USB cable into the phone. When I do this nothing happens the update just sits there. I've tried this with both PC companion and SEUS and then same thing happens on both. I've also tried updating from the phone but it says it's up to date. I'm in Ireland on O2 and my firmware is 1.6 and build is R1FA016.

I am thinking about rooting my X10i so I can get the great apps that I have seen that are unfortunately limited to rooted phones only.
What is the quickest and easiest way to root my X10i on firmware R2BA026? (please proved any links necessary)
Will everything on my phone be deleted during rooting process?
Will I still be able to get future updates with SEUS or OTA like usual, or will I need to re-root each time.
What are the pros and cons of rooting?
Is there any well known problems when rooting with R2BA026 firmware? If so what are they and can they be resolved easily?
Also, if I cannot install updates via SEUS or OTA, is there anyway to have root access and still be able to do this? What would you recommend I do?

For about 3 - 4 weeks ago, I had a problem with my phone after updating the firmware, that there would be some source code running in the right side of the screen, I wrote about it in here and some one told me that I should use pc companion to reset my phone, I did it and it helped or at least I thought it helped. The day after my phone ran out off battery, and when it was charged I turned on my phone and the proble was there again, and since then, every time the phone is turned off and back on again I can start with resetting the phone too get the source code away.
So what can I do? Can I restore to the original firmware again or is that impossible? Because I'm so close of throwing the phone on the ground from 3'rd floor and go back to my iphone again. Another problem, I use the program in the phone to backup all my contacts, sms, call info and so on, but when I restore after a reset ALL my contacts is gone, and yes I have marked the contacts to be backed up.

I am using Sony Ericsson Xperia X10 mini pro with 1.6 firmware very recently purchased, As i dont have the android market icon, i just done Factory Reset to my handset and after that i noticed that my contacts in the phone book gets errased whenever i switch off my mobile and again switch on my phone book contacts are completely erased..... again i need to restore it from Back up and Restore application which is present defaultly.
So everytime I am Restoring my contacts and again it gets refreshed. I even reinstalled my OS android 1.6 (as 2.1 notification i didn't get) even after reinstalling i am facing the same problem no contacts on my phone book.
Is there any solutions for this ..........? you all guys knows very well that if there is a problem with phone book (contacts) how hectic it is......... no use of using mobiles then......... i am missing the important contacts everytime.
so everytime i am doing back up and doing restoring........ I dont use any synchornized apps.... i use the "Back up & Restore" application which came along with my mobile and I haven't installed any new apps till now....
Note:
Actually before doing Factory Reset the phone book worked fine no refreshments of contacts happened.

I bought my phone 3 months ago and I had no problem with it "except the usual low in-call volume and battery life" but then I went on and I updated to R2BA026 firmware. First I did it OTA and the phone started restarting by itself and entering into constant restart loops. So I though it was a defective update and reupdated the device through SEUS to the same version but the problem is still there. The only way to get the device out of the restart loop is to take out the battery for few minutes and then put it back and start it, it works fine for a day or two and then it does the same thing and the problem appears again. I tried removing all applications and removing the memory card but the problem still appears and there is nothing I can do about.

I just bought my SE x10 mini pro and today I said that there was some firmware updates for it. Then I updated the phone through PC companion and followed the screen and after a while the phone was updated. But then my problem started, I have some source code / text running in the upper right corner of my phone screen all the time. Every time I'm starting a new program or returning to home screen I can see the commands the phone is giving. How do I get rid of it?

I have a no-brand (full price, 499 €) X10 bought in Italy as soon as released on the market. I still have the old R1FA014 firmware, and both SEUS and the OTA application say that I already have the most recent firmware. However the rest of the world had R1FA016 and now some operator-branded phones are receiving R2BA020 firmware. How it is possible that branded phones are receiving the update before full price unbranded phones? I'm so dissatisfied with Sony Ericsson. I always had Ericsson phones, but now I'm really disappointed.

I just bought a new Xperia X10 mini Pro in China during my trip there, and now continuing to other countries.
I don't read Chinese, and most of the applications pre-installed on the phone are in Chinese (including Market and SE Sync !)
Can you tell me how to upgrade the firmware to french or english version, knowing that the hardware keyboard is Qwerty

I would like to know if it is possible to upgrade/downgrade an android phone (samsung mostly) with official firmwares without the need to root? The reason is that some testing is needed on these devices and only with official firmwares it would be valid. And at will it would be nice to be able to switch versions for different test purposes.

I am planning to buy a 32 gb micro sdhc card for my Xperia X10.However, I have found tons of confusing and conflicting information here on SE forums and all over the net.To my surprise, even Sony Ericsson itself giving conflicting information regarding this.On the product page of Xperia X10 (click this link and click on the specifications), it says that Xperia X10 supports microSD up to 16GB only.Whereas the official Sony Ericsson Xperia X10 White paper (on page no.5) says that it supports -microSD, up to 32 GB. (The Sony Ericsson Xperia X10 White paper can be downloaded from this link).Now i urge someone, preferably an SE moderator or staff, to enlighten on this matter and answer how and why SE is giving contradictory and confusing statements regarding the sd card capability and compatibility for the same product?.
