**Reserved for phase 2 (tutorial on root explorer, Titanium Backup, JIT and benchmarks, and xRecovery-FreeXperiaRecovery)**

Restoring back to AT&T 1.6 Branded 1237-4604 Firmware with Root Explorer:

Make sure you run a backup first as this will wipe data. You need the app Root Explorer set to write permissions R/W (at top of the screen) then go into system/build.prop file and long press on build.prop file and open in text editor. Then change the SI number from 1234 - 4820 back to 1237-4604 in every place you find it. I think it appears 2 maybe 3 times. Then save and close. REBOOT! Then run repair software via SEUS or PC Companion. *If you have run SEUS or PC Companion since you updated to 2.1, you need delete the contents inside the folder "db" found inside the update service program wherever it is saved on your computer. **It will say that you have the latest software, but REPAIR ANYWAY! Reboot, setup, reinstall your Backup app from market, Restore. DONE!

*Root Explorer costs a couple $, but well worth it. If you have problems finding Root Explorer or do not have a paypal account, send me a PM. I will help you.

How can I get backup and restore to work on my American ATT x10
[XPERIA X10 General] darkoon@yahoo.com:
does this still apply?

"IMPORTANT:

- You should always wipe userdata if you switch between Android versions (1.6 <-> 2.1). If not your phone will keep restarting all the time"
[XPERIA X10 General] agentJBM:
To be honest, I don't know. I haven't done this since November. I would just follow the guide and use a Backup app to restore data and allow it to wipe data, because some settings might conflict.
[XPERIA X10 General] agentJBM:
AT&T blocks you from installing Sony Ericsson backup and restore, so you need to search the market for one. I recommend Titanium Backup or Mybackup Pro. They are much more useful than the SE app.

Sounds like a fairly promicing guide to help the noobs ;-)

I unzipped the rom while the phone was mounted and showing current files on my Sd card. now i found the rom on the sd in Xrecovery now have a list of 3 files: -meta-inf/

-Sd card/

System/ which one do i select and which one do i selct in the next list shown in Xrecovery. th list is

-app

-bin

-etc

-fonts

-lib

-media

-usr

-xbin
[XPERIA X10 General] agentJBM:
Are you joking? Please don't spam this thread. It only confuses everyone. I know I already helped you update.

Just in case, you obviously didn't follow the steps at all. You aren't supposed to mount SD card. Your phone should have been off. You can't use xRecovery to install. You have to use the flash tool. Delete the files. Do NOT unzip. Just put the entire ftf file in the firmware folder inside the Flash Tool folder.

xRecovery is for custom ROMs designed to be installed with xRecovery, not for flashing ftf files. They are only for the Flash Tool.
[XPERIA X10 General] The Gingerbread Man:
@adjent don't take offence or personally im trying to give advice to you to but take a look at my guide and lay it out in a similar step by step fashion and have as much detail as you can. It may help make things easier to follow and less confusing. I over explained everything in mine on purpose for these reasons. Iv tried to answer any questions possible as Iv included as much information as possible and perhaps number the steps for instructions and use more paragraphs and generally make it easier to read as a list of instructions. Take a look and see what you reckon any way. Just follow the link in the sig.
[XPERIA X10 General] agentJBM:
None taken, I appreciate your original post. Actually, I was speaking to Rollhard, not you. He already successfully updated in the guide I sent him via PM. He also rooted, JIT and xRecovery. It looks to me that he tried to use xRecovery to flash the ftf file a second time. Why? I don't know. Maybe he's playing around with xRecovery. I realize now that I never clarified the difference between flash tool files and xRecovery custom ROMs. He got ahead of me on the guide.

However, I will take a look at yours and probably number them. Just haven't gotten there yet.

EDIT:

@Gingerbread Man, it seems that he was trying to install WB's CM6 rom with xRecovery. He was unzipping the files. Don't know if he was using your guide in your signature, but I got him straightened out via PM.
[XPERIA X10 General] agentJBM:
To All, Will be incorporating xRecovery and custom ROMs into phase 3 of this guide shortly. Until then:

FTF and RAR files are for Flash Tool. RAR files must be extracted with WINRAR (Free trial download on web), and then "create bundle" with Flash Tool.

Custom ZIP files are for xRecovery. Download to sdcard. DO NOT UNZIP/EXTRACT. Wipe cache, dalvik cache, battery stats, and fix permissions in xRecovery. Then select install custom zip from sdcard in xRecovery.

Due to recent pressure from Google that all Androids get timely and current updates and security issues, I am thinking that some branded kits will eventually get the official 2.3.3 update.

However, I do agree with you. That's why I said I am going back to global generic.

Would love to see how long it would take AT&T's developers to push that update out hahahaha. Probably sometime when the rest of the world is on Android 6.X

/humor off
[XPERIA X10 General] frothe3:
I agree. If I cannot use HSPA if I switched back to stock and used that at&t update,I won't go back. I don't even know what the included in the update. I have been,as well as many of us,FOR MONTHS about the lack of an update.
[XPERIA X10 General] BigIslandBoy:
I agree mobile data is slower and shows "3G" as opposed to the "H" that I had with the global generic. Even with the At&t tweaks for the build.prop it is still seems much slower than the generic.

I also noticed that there is no enable unknown sources box to check. However, I am able to use Titainum backup and Rootexplorer with no problems.

I've applied all the tweaks I had with the generic on this new fw. I will test it for few days to see if there are any other significant differences between the 2.
[XPERIA X10 General] lightyear420:
I was wondering if they would bring this sneaky feature back :( I use side load wonder all the time, simply because it's easier than transferring an apk to my sd card so I can install it. But if I download from my phone I don't wanna have to use a USB to install an app.

I still like having the ftf file just in case something goes horribly wrong and I need to return my phone for any reason.
[XPERIA X10 General] agentJBM:
I put Titanium Backup Pro on my sdcard, and tried to install with astro file explorer, but the unknown sources error box opened. Would adb install work?
[XPERIA X10 General] xdadevelopers1222:
If you want to stay with AT&T's firmware for the X10 and want to enable the ability to install apps downloaded from 'unknown sources,' you can try this method:

Ensure that your phone is rooted.

Find and install Root Explorer and SQLite Editor. (You may need to use the 'sideload' method of installation for these apps.)

From Root Explorer, go to /data/data/com.android.providers.settings/databases/ and open the 'settings.db' file.

In SQLite Editor, go to the 'secure' table and update the value of 'install_nonmarket_apps' from '0' to '1' and save.

Exit out of all the apps and reboot the phone.

After rebooting, you still won't see 'Unknown sources' in Settings > Applications, but the ability to install non-market apps should be permanently enabled anyway.

Here's a more detailed guide:

Phone locks up and reboots

I've had the 2.1 upgrade for many weeks and I love the difference. But my phone started locking up and rebooting on its own. Finally I decided to do the repair through SEU and that's how I found out that the official 2.1 update was available. It gave me baseband 2.1.54; build 2.1.A.0.435; kernel 2.6.26; semcuser@semchost#1. I still have rebooting issues so I am going back to the global upgrade because of 'H' vs 3G. I also notice that when the phone turns on after sleep mode it does not readily update connect when I use the facebook app, I get an error that say "socket unavailable". It takes like 5 minutes before it will connect. I also still have data usage in the wee hours of the morning when the phone is charging. I've read through the posts and I am confused about what really works to correct the rebooting issue. I also wondered what tweaks can be done and how does one edit the build.prop file. What does sysctl config, autorun manager and autokiller memory do and are these recommended. Is there an upgrade to 2.2 available or is 2.1 it. I did download a fresh copy of flashtool. Thank you in advance.
[XPERIA X10 General] agentJBM:
First, firmware 2.1.A.0.435 baseband 2.1.54 IS global generic, so all you did was repair software via SEUS. The AT&T update is 2.1.A.0.492 baseband 2.1.65.

ATT Branded Firmware Information

Ok, I just flashed and removed the ATT branded firmware for 2.1

First, the latest beta of the Flashtool, works totally fine for flashing and rooting the phone without installing Superoneclick, etc.

As has been reported the 'install from other sources' requires a SQL change but even then the checkmark doesn't ungrey.

I did it to find out what applications were new, and in particular, was there a Face Recognition put into the Movie mode of the phone as was posted on the SE web pages for the ATT update. The answer is NO. It's the same service for the Face and Camera.

There are updates to the ATT apps, including the Live TV. Also they seem to have a newer installer (which may be why the other apps is still grayed out).

In addition there are two new apps, one is the SE Extension finder. This app is supposed to fine the new Timescape/Mediascape add ons. The software came with the Linkedn Timescape extension installed as well as the Linkedn app. YP (Yellow Pages, an updated Officesuite were also there.)

Since I resent being a second class customer on the ATT network, I went back to the generic 2.1 so that I can have higher HSDPA speeds but you'll need the little build.prop fixes . The generic works totally fine and once you install the Voice.apk, you're not missing anything but the ATT apps (which if you really want them, you can pretty much download from the market).

I have to say, that I liked the new boot animation with the dripping dots and deathstar in 3D. "Rethink Possible" being the new catch phrase. I should have grabbed it and changed it to "Rethink Carriers"....

Anyway, just so it's posted, there is no updated camera, face recognition from any other 2.1 update.
[XPERIA X10 General] Gadgetz:
Thanks alot agentJBM for making this tutorial noob-friendly, I had been wanting to do this ever since 2.1 starting rolling out worldwide....while me and all the other AT&T x10 owners got ignored but I was too worried about messing my phone up. This guide worked for me exactly as you spelled it out, with exception of rooting....I had to open the superuser app manually and then click root perms in order to be asked to allow SU access. But other than that, it was a breeze and I look forward to upgrading the latest and greatest when it becomes available.

At&t 2.1 Update

Nevermind i did it again and it works(:

And i also like the new boot up with the rethink possible phrase(:
[XPERIA X10 General] Gadgetz:
When I did the 2.1 update via AT&T I had the rethink possible splash screen....now that I flashed this generic rom I now have a different splash screen.....it's a rainbow of colors that kinda forms a hurricane type of look then morphs into the SE logo, i'm diggin' it. Is this not what it should be?
[XPERIA X10 General] stan.s:
You can customize the boot screen animation. Just go to the app sub forum. There's dancing androids, peeking, waving androids, apple eating android, sparkling android, etc.

AT&T updated phone but want to Unbrand it

OK So my phone is updated through update service but since it updated with AT&T branded firmware can I just Unbrand it? The reason I ask this is because my phone has the 2.1 Android and the build number is 2.1.A.0.492 and the one in the Guide is 2.1.A.0.435?, or an earlier version or is there any difference? Or should I just do all the steps even since it is already Android 2.1 to get it unbranded?

Thanks for the help!
[XPERIA X10 General] agentJBM:
2.1.A.0.435 is the unbranded global generic firmware. 2.1.A.0.492 is branded At&t. You can't unbrand the branded firmware, you can only flash unbranded firmware.

The At&t firmware has the new baseband 2.1.65, but doesn't allow apps from unknown sources, no HSPA or 3.5G, and probably won't get the official 2.3.3 Gingerbread update any time this year or ever from SE.

Unbranded global generic 2.1.A.0.435 is an older update with baseband 2.1.54, however you can install apps from unknown sources, HSPA data speed, and supposed to be one of the first to get the official 2.3.3 Gingerbread update. And none of the AT&T bloatware.
[XPERIA X10 General] Toledo_JAB:
I have at&t and have had the same speed with stock at&t 1.6 or global generic 2.1. Both versions I would get around 3Mbs down and 250-300Kbs up. A little searching through forums says at&t always shows 3g even when using hspa "H". So any true X10a handset, not x10i, is capable of H speeds regardless of firmware/android ver. I still use global 2.1 with root and optimize from flashtool. I did make a stock 1.6 ftf file, for returns & insurance.
[XPERIA X10 General] Crissynak:
ok so then I just do everything you say to do to unbrand it then... Ohh and in the flash tool file there isn't an .exe just FlashTool_0.2.9.1 which is an application and X10FlashTool which is an application and then the x10flasher file which is a jar executable which of these do I use after I transfer the firmware file? Thank so much for your help... Just recently I have really been looking into all this stuff so still a noob but learning fast because I also want to root my Nook Color ;)
[XPERIA X10 General] agentJBM:
^^ The X10flashtool application
[XPERIA X10 General] agentJBM:
A little searching would also tell you that part of the development was At&T's desire to limit or govern the speed to 3G even though it is capable of HPSA. If you use just the baseband from this firmware on another ROM you get HSPA, so it is obviously something in the firmware limiting the speed. What speeds your server uploads and downloads at determine your scores, as well as the phones capabilities.
[XPERIA X10 General] Crissynak:
Just finished the process!

I totally over analyzed the whole process! It was VERRYYY easy as long as you followed the steps which weren't many either. So I am very happy with the ease of these steps! Thank you so much for this and now gonna have fun with adding some apps that I couldn't before! :cool:

Agent JBM, question about updating to 2.3?

Agent JBM, hello I used your guide to update from 1.6 to 2.1 and haven't had any problems since, until now. When I try to update to 2.3 it says "no update available" even though the roll out map says it's available. I've tried checking from the phone and while hooked up to the PC.

I checked the phone according to the rollout map and I have "X10i GLOBAL-GGL GENERIC 1232-9897". Seems right, but aren't I supposed to be getting this update to?

I realize I can flash it but I'm the type that was looking foward to the official update, straight from the factory and I was just curious why my phone won't acknowledge the update.
[XPERIA X10 General] jrschrock:
I added both APNs (MEdia Net, MEdia Net mms) no problem. However, I will check MEdia Net to active, then after about 5 seconds, it automatically switches back to AT&T for the active APN. Is anyone else having this problem? Is there a solution?

Thanks!
[XPERIA X10 General] agentJBM:

Just upgraded to XPERIA Wolfbreak edition. The Rom comes pre-tweaked with a minimal custom load. The barebones start allows you to install only what you want, to free up memory.

Dolphin hd browser has a nice flash player control for faster pages. Netflix is a cool app also.

UPDATE: Just unlocked bootloader and flashed Doomkernel 5a. Still using wolfs XPERIA 6s. Using cpu master to overclock. Feels like a different phone, fast and smooth.

Thanks to the XDA crews for all the improvements.

UPDATE: Feb. 21 2012. just flashed Wolfs Xperia 7.0.0d with unlocked bootloader and upgraded to DoomKernel v06. using Data2SD. started out a little buggy and laggy but time and plain old reboots worked wonders. new versions have better tweaks and more cpu mods.

Hi new Xperia x10 owner. I actually unlocked my Xperia for T-mobile, so would this tutorial still work for me? And if so im a little confused to what exactly the first thing i need to do is. I installed the Titanium back up app(Free version) to back the phone up as mentioned at the beginning, but the app said i couldnt use cause my Xperia is not rooted. Im sorry if i sound stupid:( for not understanding, but i would really appreciate any help.

Thanks!!
[XPERIA X10 General] agentJBM:
You are correct. You need root for Titanium Backup. I didn't think of that. You can use "Mybackup" (free in the Market). However, once you are done, I recommend uninstalling Mybackup and using Titanium Backup in the future.
[XPERIA X10 General] xRG214:
Okay thank you and i still am able to folllow these steps inorder to get 2.1 even if its unlocked for Tmobile USA?
[XPERIA X10 General] agentJBM:
Yes, only your APN settings will be different. However, the menu/settings/Sony Ericsson/Auto Search for internet and mms function should download them for you. If not, search Google for T-mobile APN settings.

Edit: If you have an X10i, you can use global generic X10i firmware instead so your phone still says X10i, but it shouldn't make a difference if you use X10a. The difference is in the hardware configuration for different frequencies, not the firmware.
[XPERIA X10 General] xRG214:
Hey there when i try to begin the flash process it tells me ERROR install or reinstall device drivers. I cant find a solution anywhere, what do i need to do?
[XPERIA X10 General] agentJBM:
Have you run Sony Ericsson Update Service (SEUS) or PC Companion at least once before trying to use the Flash Tool? You need to do that in order for the usb drivers to be installed.

Go here to download Update Service or PC Companion. I use Update Service.

For those who are wondering or considering using 2.2+ custom ROMs, this firmware is running baseband 0.54, which in my experience is the best one for AT&T.
[XPERIA X10 General] mccutchen2012:
Much appreciated. This may be a dumb question, or maybe it just doesn't really matter to anyone, but will debranding from AT&T forfeit "AT&T Network" access to AT&T Hotspots (i.e. rather than the generic "open network" access everyone else has where you first have to have your browser redirected to their T.O.S. page and then you see the ads in it the whole time)?
[XPERIA X10 General] agentJBM:
I don't know for sure, but I am pretty confident that it does not matter. I don't have to do anything except go into Settings / wireless & networks / wifi settings / connect. But to be honest, I never connect to AT&T only Hotspots.

Edit: I have AT&T Uverse cable and wireless Internet in my house. I assume that it's basically the same network, so no you don't have to use the browser.
