You'll already have the right baseband from flashing .111. When you flash .233 exclude the baseband and your done. You'll just need to change APN settings back to Att to get your mms working again.

I never restore data. It never turns out well. Sorry to be the bearer of bad news for ya. Contact info though? Hmm. Might not be that bad. You could backup your contact data, do your thing and then restore that data on its own. If the phone doesn't like it, revert back to Google's saved contacts.

Titanium backup has never let me down.

I have never had problems restoring backups. Do selective restore and restore only downloaded apps.

System app data can be restored.

gb to gb or ics to ics should not pose any problem. But gb to ics could be a bit dicey.

Contacts and wifi settings are synced to google.

Thanks. One more question, would it be better to also manually wipe the external SD card? I see a lot of files created by Android there.
[Sony Xperia S, Acro S, Ion] josemald:
I just went through the process, got stuck on running step2.bat. I have both USB Debugging and Unknown Sources checked, however Flashtool is saying the USB debugging is off. Step2.bat is stuck in waiting for device. I've rebooted a couple of times, with no change.

Both options were checked right after flashing ICS, I assume because there was no wiping done.

When running adb start-server, nothing shows up. Adb devices gives me an empty list.

=============================================

Got it solved, I had to update the driver under Control Pane/Device Manager/LT28. Just running the automatic update made Windows change it from LT28 to Sony sa0103 ADB Interface Driver.
[Sony Xperia S, Acro S, Ion] KEB64:
I always did when installing ROMs and the ICS leak on my old phone. Just backup the files you wanna keep. I think this is a good general practice when coming from one major release to another. Let the new OS format the external card during the new install.

Problem fixed :D

I was not unzipping the downloaded file, just renaming it (a trick for X10 downloads)

Please unzip the downloaded file then flash.

Once I pulled my head out of my butt and thanks to spectre51, it took 10 minutes to flash&root the LT28h ICS firmware with LTE, on my at&t LT28at

#######ok so i am starting to pull out my hair. I have experience flashing/unlocking/rooting from my x10. now i am running into a problem with flashtool. flashtool will recognize all of my x10 roms and display info in flash screen (device, version, branding) flashtool will NOT display/find any of the ION's firmware.

I have tried downloading LT28h several times (thinking the download was bad) also tried LT28i and also tried the ICS variants none of them show up in flashtool. I have tried draging and dropping and again x10 roms work but ION's are no go.

I am using a stock AT&T ION LT28at

EDIT: I just noticed that in flashtool the log doesn't show the ION's kernel "Android version : 2.3.7 / kernel version :"#######

OP can you add to the guide in Post #2 to start with GB .111 instead of AT&T firmware so that people don't lose the tethering options.
[Sony Xperia S, Acro S, Ion] ganeshbiyer:
Sure ... adding it right now
[Sony Xperia S, Acro S, Ion] 424aca:
what do you mean by path is setup for Android Sdk? What should the path value be?
[Sony Xperia S, Acro S, Ion] ganeshbiyer:
It means, when you install android sdk, the paths are not automatically set in the environment Path variable.

So when you are in command prompt and type adb, windows will not be able to find it.

So it is better to add the adroid sdk paths to this variable.

goto Control Panel\System and Security\System

click Advanced System Settings

click Environment Variable button

under System Variable, you will find Path variable

and add the Android Sdk path, platform-tools path
[Sony Xperia S, Acro S, Ion] zackspeed:
Thought I would add this so we all know.

So after going from ATT firmware to ICS and getting root I did not have any issue. Did have a few bugs but may have been my fault. The one thing to note is that if your on ICS it will not flash back to the .111 firmware and will give a error and throw you into a loop. Now I finally got it to flash the stock ATT firmware again. I can not get it to flash the .111 with or without wipe. Just gives a error. I have included a snap of the error. Not sure what the deal is but has been quite odd.
[Sony Xperia S, Acro S, Ion] Spectre51:
Try redownloading .111. You can go from ics to .111 I have done it. By going from AT&T rom to ICS you probably don't have any tethering settings.

[Sony Xperia S, Acro S, Ion] zackspeed:
Not really worried about tethering settings as I don't use it much anymore and would just make it easier for me to bump my 3 gigs lol. I have tried downloading twice now. What sent me into boot loop was going from ATT to ICS to .111. I have now also tried going from ATT to .111 with wipe and without wipe and get the same error as I posted above and have to re-flash ATT again with wipe to make it work again.

I am going to try and go back to ICS from ATT again and gain root. My only real issues where I had no 4g and could not get the PS app to load or play games. The 4g was my fault as I realized I never flashed the .111 base-band.

reply greatly appreciated

same question raised in another post though
[Sony Xperia S, Acro S, Ion] zackspeed:
Think I got it now.

Ok I have managed to go from ICS to .111. Had to update to the most recent Flashtools and yes I should have done that to begin with. Redid all my drivers and made sure to put the device in flash mode and let that driver load as well. I was also having a system mount R\W error and it was due to busybox not being seen by flashtools. So used JRummys installer on the market and got some busybox. Once all of that was done it let me flash back from ICS to .111.

You can't root GB on the ion, the exploit we're using is for ICS, hence why the procedure reads the way it does.

Same way you flash any ftf firmware file.....with flashtool. Look at the pictures included in the first couple of posts

Actually there is. You are in the data folder of the archive....go to the root of the extracted zip file and there should be the folder structure as seen in the attached picture (actually I copied the three adb files to the root directory when I was playing around so it should just be step1 and step2.bat plus the data folder) You run step1.bat and step2.bat from there not the data folder.

I am quitting the ICS upgrade.I tried and the phone only works as a phone. No data at all, so my phone became a "not-very-smart-phone".

If I do not want tethering ability, can I flash the ATT baseband at the end, instead of the 111?

Will that make the 4G icon appear in status bar?
[Sony Xperia S, Acro S, Ion] SErooted:
i have manually put in apns as well and still have not been getting data on my phone. i have pulled apns off my atrix my atrix hd and my other xperia ion. if i run with the .111 firmware i am able to recieve data. but it does not show as 4g. however when i have flashed .111 firmware. then ics. i have not data at all. even after manually putting in apn settings. i know it makes me sound like a noob with the issue i am having but i assure you all that im not. i guess i just might be having a case of idiocy or something and jsut cant get it done the right way. ill check on your ideas just to make sure i haven;t missed anything and will report back... with the answer... which might just be a had a der der der moment.

EDIT... so now i have reflashed .111 ran bat1 file for root. flashed ics excluding baseband. ran bat2 file... and now have no root. the joys of playing around with your phone. if it dont work the first time . flash flash flash flash. hahaha im sure ill get it going again. no worries.

Edit: so again i have flashed and got root and running ics no prob. still have no data after entering apns manually. i know this cause i cant recieve or send pics or make an internet connection.

I was going to say - you might not in the LTE area. The APN you put above is for ATT HSDPA (not LTE as you named it) and you dont really need to put the MMS apn.

People are confused between 4G & LTE. Here are comperasion:

US vs International

4G = HSDPA

LTE = 4G

I could be wrong - For stock ATT firmware, you might able to use the LTE apn regardless you're in LTE area or not. For international firmware, if you're not in an LTE you do need to put in both apns - HSPDA & LTE.

Or it could be that you never update your account with ATT to LTE ready, so you always have to use HSDPA apn.

Hope that help.
