I'm using this rom (kernel, baseband and system rom too) on my arc (LT15i) and working well :) Battery life now 1 day 5 hour and now left 55% :) (Data ON, Autosync on, 2-3 hour wifi, 2 hour phone calling, app installing, and more), 3D games working me, but I testing just on Angry Birds Space and Six Guns.

- One bug like other user: video recording laggy (I testing some settings on camera, but laggy :( )

- I'm making some photos and photos size big on ICS, one photo 1.5-1.8 MB, on GB just 0.8-1 MB.

Free RAM: 120-130MB just, enough :) No lagg on launcher or another apps :)

Hi there i followed youre advice and im still getting failed to verify sin header error. wotan doesnt even flash it for me however wotan flashes any gb rom for me. why does wotan flash for me but flash tool and seus does not? thats what i dont understand
[Xperia Arc Android Development] Bin4ry:
I think you may have unlocked yout bootloader with Wotan ? If yes blame them.

Regards
[Xperia Arc Android Development] rkanwar:
My bootloader was unlocked with setool
[Xperia Arc Android Development] tcpma:
how many apps are useless but also installed in our phones... your view isn't absolute. if it's possible, I would try that feature
[Xperia Arc Android Development] itsmyname:
What if I wanted to root it, how would i do that? And would flashing ICS get rid of my old files?
[Xperia Arc Android Development] gen_scheisskopf:
I did unlock bootloader with Wotan (I had to remove simlock) but there are no problems with any flashing
[Xperia Arc Android Development] bbsk2:
dear all

any ARC S user (with ICS) can run "temple run " smooth?
[Xperia Arc Android Development] hollow1:
Until today, I still hard to decide whether to update my Arc S from GB to ICS or not. Though I have read several posts and topics on the advantage and performance of ICS, ICS still not yet be rooted unless unlock bootloader. And I don't want to go for that unlock bootloader only to mess up the device.

Still I need some more advice from you all, if possible in simple details around this ICS. As some idea said that ICS use up more RAM and CPU while my device has only 512 RAM and a single core. Also I have many applications and huge games installed, which would make me lazy to reinstall everything from scratch. Moreover, those applications are always up to date.

Thanks for reading my post, and I'm waiting for your all advice.
[Xperia Arc Android Development] rashid.fairus:
yes it is smooth,but touch control gone crazy
[Xperia Arc Android Development] bern4d1:
Install v6 supercharged update 9. It really a big help for ICS on my Arc S.

now my Arc S almost as smooth as GB.

Have you tried to root by using the OP method? It's simple.

just extract in a folder and connect your phone and run the RunMe.bat

for the memory management, v6 supercharged really helps.
[Xperia Arc Android Development] Rolandh:
Do I need an unlocked Boot Loader and Root to Install or will an unrootd Arc S with locked Boot Loader be able to Install, as I'm itching to get The Official ICS ROM?

Roland
[Xperia Arc Android Development] bern4d1:
you can just flash the ftf file with flashtool 7.0 without unlock your bootloader.
[Xperia Arc Android Development] BinaryXeroMedia:
I don't understand why some are getting crazy screen control. My device had that on GB but since ICS update mine is perfect now. Very strange. My thoughts were the screen has been fixed. Also I noticed if you have a screen protector on that can cause the touch sensitivity to go off the rails. If you do try removing the protector and see if that helps.

Regards
[Xperia Arc Android Development] doomed151:
You're using an arc S, maybe only arc users are affected (like me)?
[Xperia Arc Android Development] Rolandh:
Ok, sot the ftf file and Flashtool acts like the Installer packages that you can download and install for HTC headsets?

Thanks for posting this very useful walkthrough on how to flash the ICS Update. I've flashed before but on the old X8 and my Wildfire S always ad updates OTA.

Roland
[Xperia Arc Android Development] itsmyname:
How do I update to this on a rooted but BL locked device, without losing any of my files and keeping root?
[Xperia Arc Android Development] bern4d1:
sorry, I don't know about HTC.

EDIT: @doomed: my Arc S also have the touching issue when playing temple run. (swipe right means right, also means jump sometimes)
[Xperia Arc Android Development] jtdc:
Just a quick question.

When I flash this FTF, will my baseband be updated as well?

Thanks!
[Xperia Arc Android Development] caqo71:
OK, I surrender with this ROM, I don´t know why after a while using it with no problem, and after rebooting a couple of times, my phone doesn't get mi SIM card, it says that its invalid and I loose signal. WIFI works ok, but not sim card.

If I go back to Baseband 64, the SIM card works partially... Invalid Sim card, but signal works. :(

What a Stupid issue :mad::mad:
[Xperia Arc Android Development] bern4d1:
yes it will.
[Xperia Arc Android Development] a4rocks:
Is this a problem with Arc LT15a variant? I saw another member who complained about the exact same issue after updating to baseband 70 and even reverting to baseband 64 was causing the same issue.
[Xperia Arc Android Development] spinz78:
Loving my Arc LT15i after flashing ICS, its very smooth, I have more free memory, the battery lasts longer, the interface is refreshing nd new but the best of all is the stock browser, its smooth nd fast nd the screen not jumping around while scrolling up or down

Just one problem as i cannot repair my firmware with PC companion. My phone is stock LT15i and i live in India
[Xperia Arc Android Development] tiborprogmed:
YES of course. - 70 will be your BB
[Xperia Arc Android Development] SiRIus[X]:
i'm new with unlocked bootloader. jz 1 silly question, how do i root with the script provided in post 1? kinda blur.. flashed custom kernel to get rid of the 0% battery that has been bugging me for days. the only thing now is rooting it.. don't wanna screw up again :)
[Xperia Arc Android Development] Rolandh:
I don't know where Sony get the idea that the ICS Update will mqke your phone run slower than on Ginger Bread, it's running just as fqst as Gingee Bread but with the added bonus of more App Memory, better battery life, better Widgets apart from the Facebook & Twitter

Widgets for the Official apps are the same old Widgets from when I was running Eclair on my X8. Also now I can disable the Office Viewer 6 app as it's the only stock app that is none unenstallable (as I use Documents To Go).

It's still taking some getting used to the new Settings layout but a big improvement over the stock GB ROM, and Google Chrome has got to be the best 3rd party browser there is.

Roland
[Xperia Arc Android Development] deepthroat:
I have no problem with BB 56 :)
[Xperia Arc Android Development] spinz78:
Exactly my feelings, was thinking of selling my Arc but not now, its so much fun and Sony ui is way better than Samsung

[Xperia Arc Android Development] SO2YIA:
hi iam new and i have one Q can i flash this file LT18_4.1.A.0.562_NCB.ftf on LT15i

is it the same one.
[Xperia Arc Android Development] gen_scheisskopf:
You can't.

a) this is official not rooted firmware

b) you can root it

c) GB data/settings are not compatible with ICS so you have to wipe data (but files on SD card will not be touched)
[Xperia Arc Android Development] itsmyname:
So why does the ROM have to be flashed, why not update like normal and then root afterwards?
[Xperia Arc Android Development] UserX10:
Yes you can.
[Xperia Arc Android Development] deepthroat:
I can't update like normal, can you ? :D
[Xperia Arc Android Development] gen_scheisskopf:
You can't swich from GB to ICS without data wipe (you asked about preserving your data, didn't you)
[Xperia Arc Android Development] shallumabijah:
Im currently using this rom on my lt15i lock bootloader and rooted..i also applied supercharge..all are working fine but my phone recognize my unit as arc s. I hope there will be an updated ics specially for arc only. But anyways thanks for this release.
[Xperia Arc Android Development] itsmyname:
Oh true, thought it might've been released worldwide or something.

Does anyone know if once flashed it's easy to downgrade again?

Also why can't flashing be done via wotan?
[Xperia Arc Android Development] shallumabijah:
you can use flashtool to downgrade to gb if you want.
[Xperia Arc Android Development] marcjuh:
read carefully cause people have been warnt to dont go back cauce of the 0% battery problem.....!!!!!
[Xperia Arc Android Development] hackdima:
there is no 0% when you downgrade to GB! iv allready tested!
[Xperia Arc Android Development] adielee:
You managed to get ICS up and running yet?

I read somewhere that the installation for ICS is different to GB in that it creates a partition inside the root folder as part of the system or something, hence the reason why Flashtool 0.6.9.1 came up with errors for everybody when they tried to flash.

I have limited technical ability but is it possible that your flash memory somewhere is corrupt or stopping the ICS installation from creating that partition? As far as I know that's the main fundamental difference between in the ICS and GB installation procedure.

The first time I tried to flash ICS was using FT 0.6.9.1 and Bin4ry's original post and ended up with and error and bootloop. He updated the file shortly after and I upgraded to FT 0.7.0.0 and tried again. It flashed without a single error (also selecting "no final verification test" in FT).

I'm certain you know what your doing so could it be something wrong with your flash memory? Maybe there's a way to fix it, but I can't really help you there.
[Xperia Arc Android Development] itsmyname:
Are you sure? I would go back to .42, not .52 or .62
[Xperia Arc Android Development] caqo71:
I just want to know if someone unlocked their bootloader by testpoint method, and with this room and BB-70 are having signal troubles or SIM card errors.

Someone told me that people who unlocked bootloader using testpoint putting it over the SIM plate as ground have signal issues or SIM card problems with this rom, like me :(
[Xperia Arc Android Development] chiefy009:
I didn't and I unlocked with test point method
[Xperia Arc Android Development] rkanwar:
Hi yeahh ive tried everything nothings worked for me so now im using doom's version where i fastbooted a kernel and then flashed the zip file for the "leaked" version. but doom has also stated that it is the official version but its the chinese one.

theres two things i can think of that has messed it up. either when my phone was unlocked before i bought it it was unlocked by setool but after that i could still use seus.

secondly my imei has been repaired and im guessing you use setool to do that as well and when that was done it messed something up because i cant even update via seus or via pc companion :( i think i might sell this one and buy another one
[Xperia Arc Android Development] caqo71:
But you used SIM plate as ground, or one of the battery connectors?

[Xperia Arc Android Development] jtdc:
Thanks for the responses :D

So using this my Arc will be just like from the store, pure stock official Sony ICS (for Arc S though), unrooted and all... thats fine with me.

Since I have a cwm backup of my existing setup, can I flash cwm recovery and revert/restore back to my previous setup in case I want to go back to my current state (gingerbread/arconium/doomkernel)?
[Xperia Arc Android Development] Captainblade:

[Xperia Arc Android Development] er_ne_ne:
I install this ROM, but now I´ve got problem with bluetooth.

When I pared with radiocar handsfree, I´m not able to write the parse code in arc s, that radio show me for paring.

With Gingerbread all work 100%.

Maybe could be the Baseband -70 ?¿?
[Xperia Arc Android Development] blackhats:
hello,i want to ask some questions about this ROM,currently my Arc (LT15i) on 4.0.2.A.0.42 official GB firmware:

1)do Arc (LT15i)user got more worse performance from this Arc S ROM than Arc S (LT18i) user??

2)is it safe to downgrade from ICS to GB??i've recently read that someone posted about 0 % battery issues when downgrade the phone

3)if i dont like the ROM,which GB firmware that i must get when i want to downgrade my Arc from ICS to GB??

Tks before :)
[Xperia Arc Android Development] bas-r:
Tnks for posting this and modifying Flashtool for this!

It's running happily on my Arc S at the moment, and faster than GB with the exact same app & widget list :)

You've done an excellent job!
[Xperia Arc Android Development] subhankar.ds:
There is one trick i've used...it is working 100%....

1>backup first the ftf file.:)

2>open the ftf file by 7zip. then extract the system.sin & userdata.sin. & delete both from the ftf file.

3>flash the ftf file (without system.sin & userdata.sin) by flashtool.

4>then flash the system.sin and userdata.sin by any older verson flashtool (2.8 or less) by which can be flash .sin file directly.

now voila....no error will come...you have the latest verson...:D:D
[Xperia Arc Android Development] vr5411:
I did it. With Omnius software and testpoint method. Used Sim plate.

Signal is best ever!!

No problem with sim card.

Just use stock kernel and there will be no problems with signal or WiFi.

Yes, one xdaer reported problems, but that's only report so far.
[Xperia Arc Android Development] shallumabijah:
does any one notice about battery icon, when charging only thunder logo appears in the center of battery icon,it is not moving from right to left like GB.

Is it normal? or is bug?
[Xperia Arc Android Development] Bhambya:
1) Yes it seems so. We will have to wait for official ICS for LT15i.

2) It is safe unless you go back to GB rom with 2.3.3

3) I would suggest going back to .58 or .62 or .69. Dont go back to .42 firmware, that will give you 0% problem
[Xperia Arc Android Development] spinz78:
Got the PC companion working on LT18i. So I guess the update service recognizes the ARc as LT15i and not LT18i as mentioned in the 'About software' coloumn
[Xperia Arc Android Development] blackhats:
Tks for the response,mate

Looks like i will flash the ICS ROM to my Arc,can't resist the ICS temptation :D

1,5 months of waiting will make me crazy :D
[Xperia Arc Android Development] plantunes:
Is anyone having network issues with this update?

I'm having severall calls dropping without any reason...
[Xperia Arc Android Development] deepthroat:
yes, me too - changed baseband from 70 to 42 didn't help much. Still investigating this issue ...but nothing interesting captured in logcat.
[Xperia Arc Android Development] caqo71:
It seems like Baseband 70 libs are faulty, I have another issues also. :confused:
[Xperia Arc Android Development] plantunes:
How can I update my baseband???

I have a locked bootloader and unrooted ARC.

Can I update de BB??
[Xperia Arc Android Development] iridaki:
Only with FlashTool.

And of course, also if you follow the official route and update via SEUS or PCC once an update is available.
[Xperia Arc Android Development] BinaryXeroMedia:
Hmmm..... true but I'm sure I saw arc s user experiencing those problems too. Bad flash maybe? If they did it the other way before FT7 was released that could possibly be the problem. I don't know. All I can suggest is a reflash to those with the problem that have an arc s. I have to say though. Why were Sony saying there will be lag? I have less lag than GB and I have to also say that this is the best FW made yet.... to be fair though it is Sony's second FW. First being Xperia S and second ICS for us. TBH I thought this was going to be an epic fail (No Offence Sony or Kalled) but Sony are known for epic fails. But in any case they proved me wrong and Sony..... CONGRATULATIONS. :D amazing job and can't wait to see what the future holds and ignore the ones moaning about outdated HW. I think that's what we need for now. No need for Super Powered Mobiles (I quote MOBILES) with these alleged 1.8GHZ Quad Core 1.5Ghz RAM super phones. Its a phone. Good Job Sony for remembering that this is just a phone.
[Xperia Arc Android Development] DdcCabuslay:
I once flashed from ICS back to .42 and I never got the 0% problem.
[Xperia Arc Android Development] YoBob:
Can we say revert back to our own current backup of the ROM via CWM from ICS to GB as I heard that root for this new ROM cannot be as easily achieved as using SuperOneClick?

Is there an easier method for backing up our ROM and restoring it during reversion?
[Xperia Arc Android Development] gersp:
hey guys,

after flashing this everything works well excepting WIFI. I can connect to my home WLAN and it actually works but it takes a long time to build up the connection e.g. when loading a new page on browser or when I try to listen to online radio in TuneinRadio (it connects, plays some music (5s), stops, buffers (1 min), plays...)

Does someone have the same problem like me?

LT18i
[Xperia Arc Android Development] blake .l:
Just updated my Arc S to ICS and all works good, thanks guys for all the hard work... My question is my phone is an L18a Arc S now after the update it shows my phone to be an L18i... Being it changed it from a to i will that affect anything???

[Xperia Arc Android Development] blackhats:
Juz tried the ICS ROM for Arc S (LT18) for my Arc(LT15),my review:

-the UI is laggy as sh*t,i understand that this ROM for Arc S (LT18) which have better processor so i guess i will wait for the ICS for Arc

-the animation is so cool,i love that :)

-ICS Gallery loading is very quick compared to GB Gallery

-love the font that Sony used on this ROM

i decided to downgrade my phone to GB,and my question again:

1)which Arc GB firmware that i must flash?? (.42,.58 or .62),oh yeah I need root

2)are there any specific rules that i must follow when i want t downgrade my Arc from ICS to GB?? (maybe like checking the "wipe cache" or "wipe user data" boxes on flashtool)

thks before friends :)
[Xperia Arc Android Development] Candy[MAN]:
No it won't. It will still use the 3G bands found in the LT18a. Just cosmetic.
[Xperia Arc Android Development] omarfaieq007:
well I have several Wifi issues some kind similar to yours..no solution..it sucks
[Xperia Arc Android Development] UserX10:

The following fixed my problem.

Step 1: Choose a fix channel on your router (no auto selection)

Step 2: Choose mode b-g only (not n-mode)

This worked for me.

I've got the exact same problem. With ICS rom I can't pair with my car. I don't get the prompt to enter the bluetooth pairing pin code.

Any ideas. Realling driving me crazy cause that's the only thing that frustrates me cause I need to call handsfree.
[Xperia Arc Android Development] caqo71:
Totally agree, I'm having issues with my sim card and this BB-70.

Now I have it working very well, but if I reboot the phone, I'll lose the SIM card :(

Sometimes entering to a CWM kill My SIM card too.

To fix this I have to flash back BB-64 with its libs, and then flash BB-70 again with its libs, then my sim card works again until I reboot the phone......
[Xperia Arc Android Development] ArcMan09:
can flash this rom with BB64 ... because i don"t want to have signal issues..
[Xperia Arc Android Development] DdcCabuslay:
1) Downgrade to .42 then root using whatever root exploit you have

2) Nothing specific, just do one flash and you'll be fine
[Xperia Arc Android Development] BinaryXeroMedia:
I guess this what Sony meant by lag. The arc will suffer from that until overclock is made. So the arc s has just enough processor power to handle ICS. From the experience I have on my nexus s it is very laggy on a 1Ghz processor but if over clock its fine. So we know that a 1.2Ghz processor is enough to handle ICS. But 1Ghz is a bit laggy. I wait to see the the official for arc.

How to..

Hey all. First off just wanted to say this awesome work you guys are doing!

Before I go about flashing anything to my phone..could someone please help me out with a few questions..

I have stock everything on my Arc LT15. Bootloader cannot be unlocked. It is not rooted.

Am I still able to flash this via flashtool? Do I need to have root or CWM recovery? Do I need to have an unlocked bootloader?

Your time and help is greatly appreciated. Thank you :-)

EDIT*

Here's some more info regarding my phone and the situation now.

My Xperia is LT15a, but I recently got it repaired...

and now it says LT18a instead. =S

I have a big problem I don't see the "No Final Verification Check" box I have tried on several computers and my device is now partial flashed and unable to do any thing with it. when it starts it only shows a triangle with a explanation mark and a phone. after that is switches off.

I have applied the update numerous times

any change that you could give me a update so I can flash my device with the No Final Verification Check"?
