i'm out of luck...according to AT&T, its a very common problem well documented before the update...and worse, is a fundamental hardware issue.

at first i though no way towards hardware, but i've tried everything since i returned from work this evening. rooted various ICS firmwares and wiped all battery stats, tried 4 different firmwares, purposely mismatched kernels/basebands...nothing had any effect on my wonky indicated battery stats...

I've put more details in the troubleshooting forum...its safe at this point to say my problem is not a bug with the new AT&T firmware, just an annoying coincidence...
[Sony Xperia S, Acro S, Ion] Parastie:
This used to happen all the time with the HTC Desire when screwing around with different roms/kernals. Here's how we fixed it:

Run the phone until the battery is dead.

Leave the phone off and plug it in and let it fully charge (green indicator)

Boot directly into CWM (do not fully boot into ROM)

Clearn battery stats in CWM

Shut down (do not reboot)

Unplug from power (you did leave it plugged in right?)

Boot normally

Can't promise this will work, but it did work on my Desire a few times. Good luck!
[Sony Xperia S, Acro S, Ion] jtr165:
^i tried that multiple times, but thanks. Nothing seemed to make any difference at all.

AT&T is sending me a refurbished Ion for completely free, should be here tomorrow. I'll take it, but am a little worried its just going to keep happening. I'm not buying the hardware side of it...I had to have messed something up haha...
[Sony Xperia S, Acro S, Ion] Bugly Astard:
Coincidentally, after I updated to the new att firmware, my battery bar was being very strange, going to 1 percent, reboot went back up to good charge. Also charge would stick at certain points. I tried the battery stat wipe, all the usual rituals, to no avail.

I previously never had this problem, but I went back to 6.1.E.3.7 fresh install, no problems since. Working like a champ!

Question:

Is there any Stock ROM for LT28i Generic (unbranded) from another contry? No Hong Kong ROM, central europe or another placer but not from asia?

thanks!
[Sony Xperia S, Acro S, Ion] jtr165:
forgot to mention it here as well...

got the refurb'd ion, was instructed to remove the sim card from original device, boot original device, and do all the obvious data wiping and factory reset options before mailing it in.

as soon as the phone booted without the sim, battery icon flickered, and returned to normal. Been fine ever since. Flashed back to latest generic ICS, still no problems. unrooted for now, but i can nearly guarantee it was an OTA bug like others had mentioned...

Is it possible to flash the art firmware via clockwork mod?
[Sony Xperia S, Acro S, Ion] PherChe:
Well.. i was tired to use a Hong Kong Firmware, so i decided to find another option, and finally i found three new firmware, one from US and i think two from Mexico (Telcel & Generic).

but for now, this is the link from US Generic 6.1.E.3.7 (even the started apps are different to HK).

see you.

[Sony Xperia S, Acro S, Ion] Spectre51:
There is no US generic as the only ions officially from US markets are the LT28at which has AT&T branded firmware.

[Sony Xperia S, Acro S, Ion] PherChe:
Really?, the SI number is different, and when start the phone the first time shows English US, Español US and the Lang of my SIM Card... w/e no more HK firm =)

I found:
[Sony Xperia S, Acro S, Ion] Spectre51:
So what is the si number you have? Unless its a new model being sold through 3rd party retailers because Sony isn't selling the lt28i directly in the US due to the agreement with att. But since att isn't selling the device anymore maybe they released a generic....haven't heard.

I'll see if I can find out.

Just want the easy way so I can go back to stock when att releases the jelly bean firmware some time next month
[Sony Xperia S, Acro S, Ion] Toledo_JAB:
The easiest way is to flash the att stock ftf file.

Going back to a att firmware will take a full wipe. So you will have to backup everything.

HOWEVER att will not release jelly bean, they no longer carry the phone.

And the international firmware is better, I find att very glitchy.

[Sony Xperia S, Acro S, Ion] ccrowe3:
I'd rather have the LT28i or h firmware on my phone anyway. AT&T can eat a big one until they allow the bootloader to be unlocked. I just wish Sony would hurry up with the update.

[Sony Xperia S, Acro S, Ion] Najuto9tail:
Thanks I was using a custom rom and since it is slow I am going to flash a stock rom and at&t version sucks. LOL

After flashing stock do I need to reflash CWM?

Edit- I flashed CWM with a .bat from a root kit I had for xperia.
[Sony Xperia S, Acro S, Ion] zackspeed:
Spectre do you not think Sony will unlock it like they did with the R800x?? Seems like they would but hey in this crazy world nothing surprises me anymore lol.
[Sony Xperia S, Acro S, Ion] petes67bird:
My phone is going to crap. I press a contact to make a call and it takes 15 seconds for it to start dialing. If you press it again, it will call the number twice, with the second time being after you hang up the first call. Today I pressed a contact, and it called a completely different contact that is located nowhere near where I touched. My wife and I both have the ion, and we both share the same issues. We barely have had these phones a year and I am on my 3rd phone. These phones are terrible and Sony knows it. I was a Sony fan until I bought their phones. Now I am not going to buy a Sony anything in the near future. I cannot afford to buy 2 new phones and I am stuck with these for 12 more months. I wish Sony would replace these phones with ones that worked. Half the time we get missed calls and nothing rings as well. Terrible that a phone cannot function it's primary focus properly.
[Sony Xperia S, Acro S, Ion] Zachinater:
Try flashing the generic firmware
[Sony Xperia S, Acro S, Ion] Spectre51:
In talking with my contacts at Sony they said its up to AT&T to allow it since the device is exclusive to them in the US.
[Sony Xperia S, Acro S, Ion] Spectre51:
It's not my opinion...I get my info from a very reputable person who is directly involved with the carrier relationship. I don't put any stock into what a retail clerk/manager or customer service rep on the phone says. They often times have no clue what they are talking about and aren't privy to the behind the scenes.

I check almost every week to see if there is any change with AT&T's plan hoping they will release it but it doesn't change. The LT28i firmware will be what we will use if we want JB. Don't believe me or think its is just my opinion? That's fine whatever floats your boat. I only share what info I get and it has prove reliable in the past. Enjoy your ion, I'll move along now.
[Sony Xperia S, Acro S, Ion] zackspeed:
Well that kinda sucks. But lesson learned as in buy a unlocked device next time around I guess ;).
[Sony Xperia S, Acro S, Ion] Spectre51:
Yeh that's always the benefit of the unlocked devices. But you can't get them in contract so you have to fork over the extra cash. Carriers in the US suck. I'll see if I can get a eta on the generic firmware.

[Sony Xperia S, Acro S, Ion] petes67bird:
Thanks. I have never flashed before so when this is released I will be doing it for the first time. When you flash, you don't lose all your settings do you?
[Sony Xperia S, Acro S, Ion] Spectre51:
Well if you flash via FTF you can uncheck the wipe data options and it does work sometimes but it also could cause issues. best thing to do is use the Sony Backup & Restore app or another backup app then do a fresh install wiping everything then restore from those backups.
[Sony Xperia S, Acro S, Ion] petes67bird:
Will that save my apps and arrangement on my home screen? I have already had to redo this 3x as I am on my 3rd ion. My other concern is losing my pictures. Thanks spectre for helping a newbie. I am gonna google ftf as I have no idea what that is. Hoping I can do this without purchasing anything extra.
[Sony Xperia S, Acro S, Ion] Spectre51:
Don't need to buy anything extra. Read up in the threads here specifically the stickied ones. It should keep apps and pictures and app placement as long as you don't wipe data.

[Sony Xperia S, Acro S, Ion] Bach415:
I got a feeling it's working for them and they have an unlocked bootloader because of their Ion. Maybe their Ion is actually a LT28i but flashed with AT&T GB firmware before they were sold.

That file seems to make no difference in flashing ICS to LT28at. Still the same error.

I honestly don't know. I haven't unlocked it, so it probably isn't. I guess I could unlock it. How would I flash it?

Took delivery of my AT&T Ion today. Played with it for about 15 minutes then flashed the Hong Kong firmware. Setting it up now :D

Thanks so much for providing the firmware. Can't wait to get this rooted and I hope the ICS and bootloader get worked out soon. Wish I could contribute more tho :eek:

Just realized that the 4G icon no longer is there at my house. Just "H"... not sure if the speeds are different and I have "LTE preferred" selected in the settings. Is there a fix to get LTE working on the generic firmware?

Copied all the network settings you posted exactly
[Sony Xperia S, Acro S, Ion] Spectre51:
I believe it's still working just a different icon for the network. Maybe I'll flash back to generic and see. If it changes for LTE like it does on the AT&T firmware. I'm sure once we get root and stuff we can change the frameworks to make the generic have the same network symbols.
[Sony Xperia S, Acro S, Ion] Bach415:
Mine says 4g lte for the 4g. I'm on the hk international firmware but I did not wipe any data when flashing over.
[Sony Xperia S, Acro S, Ion] Spectre51:
So when on LTE it changes from just the H to something that says LTE?
[Sony Xperia S, Acro S, Ion] Spectre51:
Okay so we've got what 2 maybe three people that said that ICS ftf worked for them? Can those of you that did get it to work post what model your ion is, whether the bootloader was/is unlocked or unlockable and where you got your ion. Also post some pictures of the home screen and the Swoftware Info screen ( dial *#*#7378423#*#* go to Service info then software info) also the Simlock info screen and configuration screen.

LT28i then ICS

Question. If it is possible to flash the international version but not the ICS version from stock GB-LT28at. Then would it be possible to flash the international GB-LT28i, then immediately flash the ICS-lt28at version afterwards?

Sorry for the noob question, I am new to the android scene and still figuring everything out.

Anyone with a LT28at who flashed to LT28i fw 3.7 did your headphones work? When I flashed to LT28i 3.7 my headphones were no longer recognized, it's as if they weren't even plugged in. I tried this on 2 different ion's the the same result..once I flashed back to stock ATT they started working again..Frustrating since I use my phone for music when exercising, and I much prefer to use the international fw.. Just wondering if anyone else has ran into this?
[Sony Xperia S, Acro S, Ion] zackspeed:
I have run into this a few times. Sometimes when I plug in my headphones it wont work but I cant pull them out and plug it back in and they work. It does not do it very often so I have never really worried about it.
[Sony Xperia S, Acro S, Ion] drogers81:
It's odd, but I re-flashed back to generic 3.7 and now they are working perfectly with my headphones..My phone also seems to run a lot smoother/quicker this second time around also.(Probably just my imagination :) )

[Sony Xperia S, Acro S, Ion] zackspeed:
Try using the deodexed international firmware 3.7 and then flash the att .111 baseband. I am having very good luck with this combination. It is also not a bad idea to reboot every couple of days.

Everything should work fine except LTE as the H does not have the radio for it. Though if it where me I would use the setup above this as it has been my best experience. Plus if you end up some where with LTE you will have it :good:
[Sony Xperia S, Acro S, Ion] optimumpro:
You should be able to provided that lt28h and at28 have the same hardware. You don't need to flash the entire firmware, just the baseband....
[Sony Xperia S, Acro S, Ion] petes67bird:
Wow jelly bean is not coming out for the ion. It is months overdue
[Sony Xperia S, Acro S, Ion] optimumpro:
No big loss, especially in light of recent revelations about government spying. The last good firmware for ION was gingerbread, which was stable and secure. GB works fine with java applications and Permissions Denied. The latter is essential in protecting your phone from being taken over remotely. Permissions Denied was able to safely remove spying permissions such as call phone, call phone privileged, send SMS without notification, record audio, camera, watch keystrokes and many others. In addition, you can prevent your phone (microphone/camera) from being activated remotely without you knowing it. Most importantly, unlike Pdroid and LBE Guard, Permissions Denied removes permissions on the application level, which saves battery. Come ICS and Google removes these capabilities. While you can still install Permissions Denied, once you restrict permissions and lock them, your phone wouldn't start or freeze. Also gone is java support.

Moderating from my Xperia ION :D
[Sony Xperia S, Acro S, Ion] Taosaur:
Heh, I knew I should have gone back into the post and noted that yes, I did look inside the zip, and found ROM folders rather than a FTF.

ETA: I just torrented the FTF from this thread--I just needed a JB kernel.
[Sony Xperia S, Acro S, Ion] Toledo_JAB:
As a .ftf file is a version of a 7Zip file, you can view the contents.

Did you unzip the .zip file and look inside the folder to see the single ftf file?

I just finished my download, unziped and flashed JB since I posted earlier.

ION stock downloads are zipped up .ftf files

Pre-rooted/ pre-rooted & de-odexed files from the other thread are in the CWM zip file format.

its will feel so great if somebody could make a rooted jb ftf straight away, so we dont have to flash stock ics and root and install cwm and flash stock jb kernel again. could anyone please??
[Sony Xperia S, Acro S, Ion] Spectre51:
No can't flash custom roms through flashtools as FTF files. FTF files are only stock firmwares. They have to be flashed through recovery or through fastboot mode for unlocked bootloader devices.
[Sony Xperia S, Acro S, Ion] Taosaur:
Ah, I just noticed that it looked like a duplicate of the CWM zip I'd downloaded from the other thread and checked by double clicking on it to see the contents, which apparently is not a good way of checking :o

Glad it's working, regardless, and I found another way myself. One way to make things less confusing for everyone using the other thread and save us all some bandwidth would be uploading kernel-only FTFs and posting the links in the OP of the pre-rooted thread, making the whole thing less of a scavenger hunt.
