Updating to V2.1 on a locked phone

I am trying to unlock my x10a locked to ATT, I purchased the unlocking code but it seems that mi unlocking code cannot be found on the unlocking server.
They offered me the unlocking software which requires to be running android 2.1.
So the deal is that I don’t know what is the version that the cel is running, I will think is not 2.1, but I don’t know how to tell, so how can I update the cel to android 2.1 on a locked phone.
BTW I don’t have any ATT sim
PLS help!!!

flashtool will probably still work!

Does your lockscreen have and arc you have to swipe or a straight line at the bottom to unlock (like iPhone)?
If you have the arc swipe to leave lockscreen then you're on 1.6.
If you got the straight swipe line, then your on 2.1.
You can check your Android version by going to:
Settings>About Phone
And check what it says in the Firmware version field.

Yes I have the Arc so I'm on 1.6
I can't go to setting I can only do an emergency call.

Ahh yea the AT&T restrictions. Forgot about those, on generic firmwares you can boot up without a SIM in the phone.
Well you just have to flash a generic X10a firmware with FlashTool then.
To be safe get the X10a (2.0.A.0.504) firmware.
Not confirmed this myself, but I think going from 1.6 to 2.1 requires you initially flash 2.0.A.0.504 before any other 2.1 firmware (But I'm really not certain about this, so this is just a safety precaution on my part).
This can all be found in the FlashTool thread here:
http://forum.xda-developers.com/showthread.php?t=920746
Then just flash that and then you'll be ready for your cable unlock.

Is there a matrix of FW releases??

Yea there is a lot, but if you checked my link you would see there is only 3 generic firmwares for each device (X10i & X10a) in the link.

ok arkedk thanks for the help, will download that and check if it helps.

Why flash old 2.0.A.0.504 firmware without dualtouch?
Here's a step by step guide for AT&T X10a users to update to the most recent global generic 2.1.A.0.435 firmware, which has dualtouch and will be certain to get the official 2.3.3 Gingerbread update directly from SE when available.

Told him to flash that because I remember someone long ago said that going from 1.6 to the latest 2.1 could cause problems. But was not certain on that so better safe than sorry. And either way he will be able to get 2.3 on 2.0.A.0.504 just aswell as on 2.1.A.0.435. This was just so he could get the device unlocked in the safest possible way I could recommend. He can always just connect the X10 to SEUS after he has unlocked, and then it will update him to the latest 2.1.A.0.435

On x10unlocked.com it says that I shouldn't have a custom firmware installed.
That's the software the company provided me with.
Please advice

Am i missing something here, but wont pc companion or seus put everyone on the latest official 2.1 version from se with no problems
Then he can unlock easy with flashtool.
Edit
So, download seus or pc companion from se website, instal and follow the instructions. You don't even have to be able to turn the phone on for it to work

Not any kit. If you want the bloatware branded ATT 2.1 firmware that limits data speeds and blocks apps from unknown sources. Also, most branded kits will not be getting the Gingerbread update.

What i seem to think his problem is is that he cant unlock on SETool because he is on 1.6 and that only works with stock 2.1
So he needs 2.1 on his phone which he is struggling with.
So, use official means to upgrade to the official 2.1, unlock using SETool, then use flashtool to root, install recovery and flash any firmware or custom rom he wants.
Why the worry about dual touch drivers etc etc.....once its rooted you can get rid of bloatware, easily flash generic firmware and receive 2.3 update....
I am confused as to why this poses a problem.

Enabling apps from unknown sources isn't as easy as rooting with ATT. Also, data is throttled down to 3G.
You even suggest flashing generic after updating via SEUS or PCC. Why add all these extra steps? This is xda. You can accomplish everything with global generic 2.1.A.0.435 firmware in about 5 minutes with the flash tool.

Well What I did was use Sony Ericsson Update Service, when I connected the phone it told me that there is a newer version so it updated it to firmware version 2.1-update1. So I was able to unlock the phone using multi unlock. Now to get the latest firmware which I understood it is 2.1.A.0.435 with Flash Tool.
Can I go straight from 2.1-update1 to 2.1.A.0.435?
And a last question a generic firmware means that I won’t have all those useless ATT apps on my phone?
Thanks for the help

Yea a generic firmware is one without any branded apps, special setup or limited features.
The latest generic was released for the German generic kits an has build version 2.1.B.0.1. You can find it in my signature.

What do you mean by German generic kits?
I apologize to be a pain but I just getting in the android world.

All Sony Ericsson devices is sold in different regions and has a region specific code. That code determines if your region is eligible for an update (Sony Ericsson rolls out their updates in regions).
Some regions gets updates that others don't get, that's the case with the 2.1.B.0.1, this firmware was only released to the German "kits".
Not a pain at all, we all have to start somewhere

Ok then I will go to 2.1.B.0.1, hopefully I won’t screw up my phone since this is the first time doing this

Okeyy
Thank you bro. I will download .ftf today and upgrade

I have not seen any improvements whatsoever in this release. The touchscreen keyboard is still a bit hit and miss. And the fingerprint hardware unavailable still appears.
The only good thing about this update is bringing the security patch level to 1 June. Which is outdated, other vendors are getting the 1 August one already.
Strange to be such a big update though 500MB+.

Things i noticed in this update (I'm using VN firmware):
- New homescreen which allows rotation.
- June security patch.
- The touch issue mentioned in this thread has been fixed.
- Better fingerprint recognition. Battery life seems to be improved (a bit).
- Gaming performance is a hit and miss. Dead Effect 2 and BIA3 run better, Asphalt 8 runs worse. Other games don't seem to change. (I'm not sure if A8 actually run worse or it's just me, can't get FPS without root ). Antutu score increased from 75k to 79k.
- I can't say anything about camera, as i barely use it.
Overall, unless you have nothing else to do, this update does not bring any game-changing improvements, and can be skipped. We're getting Nougat in months anyway.

Got a question guys. I got the US version, but I flashed a UK version firmware using flashtool from Androxyde to make the fingerprint scanner work. The phone is not rooted, bootloader is not unlocked. Am I getting the this update OTA or should I just flash it with flashtool again? I don’t mind to wait if OTA update is available, I just wanna make sure I’m gonna get it.

Hello

Yes, you can flash any ftf you want. I would go for a customized/generic ftf because they have less bloatware

How to update and review f8131 xperia x performance to new android 7.0 nougat.

Hey there, this is a Guide to Update the Xperia X Performance F8131 To the new Android 7.0 Nougat, also with a Small Review if you want to know what’s new, or you will wait for your region to be available.
I made this guide because i had an issue that i tried to flash the FTF via flash tool, but it is useless the flash tool needs to be updated before we can flash android 7.0 Updates. DO NOT TRY TO FLASH THE _39.2.A.0.327 YOU WILL BREAK THE SYSTEM OF YOUR PHONE. Also for those like me that doesn't want to wait for the update to be available in your region.
First of All i am not responsible of bricked phones by using this guide.
Review about the Software (WITH SCREENSHOTS)​
Well First of All is that the lockscreen have a few New Changes for the notifications and the clock (its bigger Now)
Now the Quick Widgets in the notification bar are now small al of them.
Also the Wifi and antenna icons are slightly different
Now we have Stamina levels that we can Change to get better Battery.
On Camera we have the new Camera APP that Xperia XZ Has that can change many more things in manual mode.
Contact and Dialer have a few Changes.
It feels Slightly Faster than before, so you can check it up.
Thats all i can tell from now, we will see in the time.
Process to do the Update:​1- You will need the latest flash tool available, you can download it in http://www.flashtool.net/downloads.php if you don’t know how to use this tool, please search on the internet first.
2- You will need the software update F8131 35.0.A.1.275 Customized RU you can download it here: https://drive.google.com/file/d/0BxPbn7RHkJD1WElDV2xHMkhyMzg/view Thanks to [email protected]
3- What you will actually do, it’s to flash the 6.0 MM ftf on your phone for Russia because in that region it’s available to download OTA the Update for 7.0 Nougat.
4- Flash the downloaded FTF on your phone with the usual method (Remember to charge your phone at least at 80%, you will need that battery).
5- When your phone finished and booted, just connect to a Wireless Network and go to settings ----> About Phone -----> Software Update and click update and let it work.
6- You will do 2 updates, one to the 6.0 Update .297 and then the 7.0 Nougat update will be available.
7- Enjoy the new software Update

Stock ROM for Xperia X Compact?

Hi, I assume someone much smarter than me will be able to point me to a Sony Xperia standard/stock ROM which I can flash with TWRP.
I had loaded TWRP and manages to accidentally wipe out the system with no backup (it's a new phone anyway). I found some ROMS from European telcos, etc. but would like to install the "standard" Sony Xperia ROM for XC.
Thanks in advance to anyone who can help.
PS. I think it would be easiest for me to able to install it through TWRP.... but obviously, anyway to recover my phone would be great.
PPS. Still can access device with adb and Flashtool, but not from Fastboot or Sony PC Companion.
PPS. I have installed OmniROM in the meantime... but don't want to spend too much time on it if I am going to wipe it out anyway.
PPS. I am in the US.
Update:
I found XperiaFirmware. It's downloading F5321_34.1.A.3.49_CE.ftf. Per the download website, will take about 18 hours on average, but it is progressing better than that.
I also found XperiFirm tool which downloads much faster, but I don't know which version. My understanding is that US customized is for CDA version of the phone. I also ran across the post about enabling the fingerprint reader by downloading the UK customized version... But based on latest attempts to do this, since UK version has been upgraded to Nougat, this approach is not working anymore...? But anyway, I could give it a shot to try a European version which is still on MM,

Update: *Whew*
I used XperiFirm to select a ROM. I didn't know which ROM, but I was intrigued to enable the fingerprint scanner. Due to some recent posts that the original method of using the Customized UK (or as they would say "Customised UK") version no longer works as the posted firmware was for Nougat. As a workaround, some people downloaded CE version, but CE version has also been recently updated to Nougat. I noticed a CE5 version which still seemed to be the MM version.
However, I also wasn't sure what differences I may see in the European version as some posters were complaining about some cosmetic differences, so I downloaded Customized US even though I thought I read somewhere it was for CDMA network. I also decided to download one called "Commercial and Journalists" which was the same MM version.
I decided to install it first as I was anxious about trying to get my phone back. I was able to load OmniROM but since there were some known issues, my preference was to use authentic Sony firmware. In addition, I took some low light pictures with the OmniROM version, and they turned out really bad. Not sure if it was the ROM or what, but it was very disappointing. Also, I couldn't get root access to it. Also, even though OmniROM seemed to support the fingerprint scanner, I couldn't get it to register my fingerprint well.
I downloaded the Commercial and Journalists version from XperiFirm, let it unpack it, and then used FlashTool to create the bundle, not including fwinfo.xml or the .ta files.
It started up Android ok, but I noticed I seemed to have lost my TWRP. Anyway, while starting up Android, guess what? The fingerprint enabled software was there... and it works like a champ!
Since I seemed to have lost TWRP, I started from instructions again from http://www.stupdroid.com/2016/10/root-sony-xperia-x-compact.html and was able to get it back.
Then, I tried to get root, but following the instructions, I got the error ""There is no su binary installed" when opening SuperSU.
I then flashed UPDATE-SuperSU-v2.46.zip from https://download.chainfire.eu/696/supersu/
And now I have root access!
Whew! I don't know what damage I've done overall... and since I don't have a nano SIM card yet, the worst case scenario is that what I have now doesn't work as a phone (but I doubt it). After what I went through (accidentally deleting the system from my Android phone), I now have a rooted Xperia X Compact with the fingerprint sensor enabled. Sometimes it's better to be lucky than good?
And, when I took some low light pics, they turned out better!

Hi Bro,
i need a help can you please give me the web link to download UK customized ftf or CE customized ftf. please its almost a month with xperia x compact but no fingerprint working. im unable to download it with my system its very old configuration. i badly want fingerprint working on my phone. can you please upload somewhere so that i can download and flash it directly, please....

My F5321 from Malaysia isn't receiving any of the new updates. Last one was 34.4.A.2.32.
Could anyone explain why?

You can check xpericheck.com if there's a newer version,but there's a good chance there isn't one. I'm stuck on 34.4.A.2.50 on the Central Europe version for example, the newest one is .85

What now? Unlocking bootloader if you want latest security patches?

Is there another firmware variant that would be suitable for your location? There may be less difference between the variants than you might expect.

According to xpericheck, singapore region firmware is also stuck in March. I guess both MY and SG are using the sme FW. I think you cn flsh other region FW without unlocking Bootloader.

Is there a way to flash security updates only, without upgrading to oreo?

If you want to retain the fingerprint sensor operation, don't flash to US. People here have in the past recommended either DE or UK, as they tend to be updated promptly. No unlocking of bootloader needed.

Okay guys. I'm ready to flash a new firmware, probably Customised UK. Is the guide on xperiablog up to date and accurate? Also, there is a flashtool by Androxyde on flashtool dot net, but there is also a flashtool on Sony Developer World. Which one should I use?
There is only one xperifirm so that's unambiguous, at least.
Edit: also, it doesn't affect user data or the OS in general, does it?

I can only speak from personal experience with the Androxyde flashtool. I've never tried (nor even known about) the Sony flash tool. In my experience, if you don't make any changes to the default settings, the existing user data is carried over into the newly installed firmware. I'm assuming here that you're flashing from one variant of Android 8.0 to another, not from Android 7 to 8, etc.
BTW, I would always advise backing up your data first, of course. If, for some reason, you are dissatisfied with the result, you can normally get a factory installation of your currently-installed firmware by using software restore from SONY (as part of Xperia Companion).

@pseudonym58 Thanks. Is the guide on Xperia blog the one to follow or is there a better one out there?

I don't recall which guide I used. It basically runs like this:
Run Xperiafirm from within flashtool; it will refresh available software. Choose particular phone model and download desired firmware. Back in flashtool proper, connect phone in flash mode. Select downloaded firmware, which is unpacked and prepared for flashing. As I mentioned above, you should not need to make any configuration changes to the default. Flashing can now begin (it might seem to pause temporarily from time to time but don't cancel process).
Don't worry about warnings of missing elements; I have never had a flashing procedure fail as a result of a claimed missing component.
This is just a general procedure; perhaps someone else can recommend the best full tutorial.

Ok so CE1 got the newest (.107) update right now so it can probably be used too.
