Hey guys, I searched all over the net and xda forums and found lots of similar threads but I still don't know what exactly to do.
So I have Arc S (LT18i) and my phone upgraded by itself from Gingerbread to ICS stock 4.0.4 some time ago.
Today when using Emma I accidentally downgraded to stock GB 2.3.4 and now I don't know how to upgrade back to stock ICS I had before. I tried with Sony Companion because it detected new software (4.1.B.0.587) but it said it couldn't.
I actually wanted to install custom rom CyanogenMod 10.2. but I bumped into lots of things..and I ended up with downgraded version on my phone. I rooted it again and now don't know what to do.
Bootloader: unlocked
Rooted phone
Build number: 4.0.2.A.0.62
Kernel: 2.6.32.9-perf [email protected] #1
How can I upgrade back to stock ICS or if there is a way I can simply install custom rom (tho I'm a big noob and a bit scared of it)?
Please help if anyone has any links or anything that could help, thanks in advance.
Flash stock ics ftf using flashtool

Okay so I'm singing right now like a little kid!:laugh: I found out I couldn't update through Sony Companion because I had unlocked bootloader so I locked it back (flashtool) and upgraded with Companion and right now Im running on 4.0.4 ICS!
Yesterday I tried flashing stock ics but there was an error and couldn't flash it properly so I was really worried.
Thanks anyway for the answer!
if you say us the error maybe we can help you
and why you want to flash stock ics when you are running it?
You can look at *#*#SEVICE#*#* in dialer then you go to service and configuration. there is standing bootloader unlock allowed: yes i think because you are unlocked it some day ago..
i rate you down for unlocking your bootloader because you cannot run OTA and you loose your warranty.
and you can boot into fastboot so you are able to flash kernels, what means you can run all roms except some roms like cm or miui !
so flash a kernel and run a rom what you want.
If you tell us the problem, i think we can solve it
Yours,
Slimey!

Did you try
Edit: gave the most possible bad advise due to misreading.
Other way is to download seus, Sony Ericsson update service, and update through that, but for sure you lose your root rights than.
Further on all your answers will be here on the first page, so you could have done some reading first, than you would have found out asking this question is a bit ought...

Software update, your phone will check if there is an update available.
With the ota, over the air, update you have a chance you still have a rooted phone.

OTA for unlocked bootloaders will brick your phone. There is a fix for that now though.
Be careful of the advice you give.
You are right, I didn't read that, my apologise!!

You have to install flashTool 0.2.9.1. http://forum.xda-developers.com/showthread.php?t=920746
Then get the updated firmware 3.0.1.A.0.145 or 146 https://rapidshare.com/files/4055154....146_Global.7z. You can keep your settings (option i FlashTool).
Then get the rootexperia.zip from Bin4ry http://forum.xda-developers.com/showthread.php?t=1130639 and flash it via recovery http://forum.xda-developers.com/showpost.php?p=14903452&postcount=169
Hope this helps
Just flash a 2.3.3 ROM (preferably rooted) with fastboot. Look in the Development section for a ROM. Its fairly easy.
http://forum.xda-developers.com/showthread.php?t=1044201
There lots of ROMs and a very good tutorial how to flash using fastboot.
very thanks i try
i have tray and work. Very thanks
hi,
I got myself a sony ericsson xperia arc s
bought it in a store, doesnt belong to any carrier (I live in israel)
I tried upgrading to LT18i_4.1.A.0.562_NCB build,
but during the flashing process it gave me an error...
ERR_SEVERITY="MAJOR";ERR_CLASS="MEMORY_CLASS";ERR_STATIC="HASH_VER";ERR_DYNAMIC="Final data verification failed
the installation didnt go through and when i tried turning on the phone it showed the "SONY" logo, and then a symbol of a triange and "!" and a symbol of a phone - then shuts down.
I tried to flash it again but nothing helped,
eventualy I downloaded LT18a arc s_2.3.4, 4.0.2.A.0.42_Generic USA Build
and flashed it, everything works "like a charm"
but I want to put ICS on it.... any suggestions? anything I could have done wrong?
B.T.W
in the "about phone" my model number is lt18a, and on the back of the phone its written lt18i
so which one is it?
the in advance, I realy hope its the right forum....
seems like u have older version of flashtools...to flash ICS, use the latest flashtools. older version cant flash ICS..and make sure data verification is unchecked..
and it really doesn't matter if it says lt18a or 18i...maybe u flashed lt18a firmware...u need to flash lt18i firmware...
it was clearly mentioned when .562 came out officially, that final verification should be unchecked....while flashing thru flashtool (a version below v.8)
so anyone else?
the two of you gave me 2 different answers,
I didnt use an older version of Flashtool, im using the latest 0.9
any other suggestions? I just dont want to mess up the phone...
why dont you try the latest 4.0.4 firmware?
do you think it will work? im afraid it would give me that weird screen again and I wont be able to turn on the phone again,
if im currently on a 2.3.4 usa generic, can flash the latest cm7? or jjhybrid aswell? or do i need to be on 4.0.4 build before i do it?
ok, so I downloaded LT18i_4.1.B.0.431_(1254-2184)
if i understand correctly its the latest 4.0.4 for xperia divices
my device SI is (1254-1958)
Im currently using (2.3.4, 4.0.2.A.0.42_Generic USA)
My device is rooted thx to DooMLoRD's rooting tool, and of cource its bootloader is unlocked.
so in anyones opinion, can I just flash the generic rom thats listed above?
pls answer,
thnks
yea man..u can flash any .431 firmware...use the latest firmware with data verification unchecked
Ok, good news!
Managed to flash the latest FW! Am currently on 4.0.4
Everything is smooth! Battery life seems to be a bit better but only time will tell...
Anyway thx for every reply!

Hey,
I am new to this forum and have been getting great help from this forum over all. The issue is that I have been using SE Xperia ARC LT15i for almost over an year now. I was on FW 4.0.a.2.368 (2.3.3) earlier and was going pretty good with it until i decided to upgrade my ARC to ICS 4.1.B.0.587 (4.0.4) through FlashTool and rooted it with DoomLord's method.
Now the problem i am facing right now... i am not quite satisfied with it. Problems and issues are same as many of us are having. Camera performance not that good, SMS LED not working, over all the phone is quite laggy. Can't play games... touch respond not that good as compared to previous FW. I like to use camera alot but cemera performance not good specially the video player. I like to play games in my free time but games are so laggy that it's almost impossible to play. Now what should i do about it? I want suggestions.
1. Should i downgrade to 2.3.4 (4.0.2.A.0.62)?
If i downgrade... my phone would still be rooted? Bacause i heard that FW 4.0.2.A.0.62 can't be rooted. Plus how to downgrade... Through FLASHTOOL or through CWM?
2. Is there any other FW or ROM available that can still increase my phone's performance? I saw many ROMs like AOKP / CM10 / Ultimate HD but i have a locked bootloader so can't use them plus i don't know how to use CWM? I tried ROM manager, X-parts but some how I can't boot into CWM. Every time i restart my phone (press volume down key at SONY logo)... it boots in Safe Mode . I love to try new things out but some how... this CWM thingy isn't helping me out. Over all i like ICS because it has given new feeling to my phone my this laggy thing is getting on my nerves :crying:
Here\s my phone info:
Model Number: LT15i
Android Version: 4.0.4
Baseband Ver: 8x55A-AAABQOAZM-203028G-77
Kernel Ver: 2.6.32.9-perf
[email protected]#1
Build Number: 4.1.B.0.587
So which option should i go for... should i downgrade and how would i downgrade to 2.3.4 or should i go for a new ROM (Locked Bootloader plus CWM not working) help needed badly from GURUs !!!
P.S: Don't ask me to search it out... because some how i couldn't find any topic like this before. That's why i am threading it.

Thanks.... let me check it out & then respond back.

Is your boootloader locked - or unlocked?
If it is unlocked then u have no problem with rooting...
If it is locked then u can flash a .42 GB firmware via flashtools and downgrade then root it.. Then you can OTA update ur firmware and still have root..

Hi all,
I own an LT18a which appears to be an LT18i equivalent? It's an Xperia Arc S, Central American GSM version.
It is SIM unlocked however it's made after 12W11 so I cannot unlock the bootloader. In the root status it says Bootloader Unlock is not allowed.
It is trapped on Android 2.3.4 which is horrible. No OTA available.
I am wondering what my options are, I have searched but seem to hit dead ends. Is there any alternate way to unlock the bootloader, I tried a few paid services but they said after 12W11 there is no support.
Can I install leaked 4.1 official firmwares like the UK one posted here via flash tool or can I not install anything except what is OTA (nothing at the moment).
Thanks in Advance
You can install via flashtool a ftf file
Also sony have given us a update to ICS 4.0.4
U may get it from PC companion Or a ftf file
I dont think there is a leaked 4.1 update
U may also root ur phone and then install Custom GB roms for locked bootloaders

You can update to Ice Cream Sandwich, Android 4.0.4, via PC Companion.
At the moment, there is no way for you to unlock the bootloader.
There are no 4.1 official firmwares for our phones, only the ones is xda-developers.
Thanks and thanks! 4.0.4 beats 2.3.4. I will upgrade, thanks everyone!
ICS 4.0.4 might be newer but I'd say that 2.3.4/2.3.7 GB is running much smoother on our devices, so I would not upgrade your phone, but it is your choice
Hi,
today I try to flash KTG kernel on my girlfriend Arc S with ICS stock Sony rom.
I have rooted it with tool (Eroot_V1.3.4) and says rooted.
Even Flashtool says "Root access allowed" but when I try to flash KTG kernel from Flashtool on Fastboot mode, obtain an error (See attachment).
This Arc S is with Unlocked Bootloader, and works perfectly.
I want to flash KTG to install a custom ICS ROM (Zohaib one).
With my old Arc S I do it without problem...this problem never happened to me. Now I don't know how flash kernel.
I try to re-root device with Flashtool option (My LT18i-->Root) but even that options, after launched., says ROOTED, busybox installed and I see SuperUser on apps in the device.
Someone can help me? Read Flashtool video logs....what's happened?
How can I flash KTG with this problem? It's related with ?
you probably fixed that by now, and I am no expert, but I just solved a lot of my problems by using a real old flashtool v 6. something.
It had no problems acknowledging bootlader status- unlocked which I had convinced myself was relocked. It rooted no probs first try with the padlock and fastboot installed .img which I just couldnt get to happen with other versions.
I also could not uninstall system apps no matter which rom/kernel i tried, I had SU in the apps but it was if wasnt really rooted.
I am finding a lot of dead links, figures because this phone so old now, and the forums are just too big to navigate. I am now trying Rush with UHD 5.0 since today, but it is chewing through the battery, any advice?
Any old files you could send me?

I have fixed the problem selling that Arc S.. Now I'm on my Z1C only.
But thanks very much for your answer and attention...these problems are known about root.
For root ICS Arc S, use EasyRootToolKit from this forum...for me works (disable antivirus first)
As ROM, I use for years Xperia T ROM from Zohaib, that goes well and mantain stock features of Arc S.
Or, if you want to try something different, you can try "Superjellybean ROM" that goes well on my Arc S...flash SuperFusion Kernel and try the lightness of Jelly Bean 4.1.2
Have a nice day!
