[Q] How can I repair my phone after update that broke my Xperia Play?

So, I update my phone (Xperia PLAY) from Android 2.3.4, 4.0.A.2.368 to Android 2.3.4, 4.0.2.A.0.42 on my phone, when there was notification for updates. It downloaded updates and turn the screen on with some kind of package. It loaded in little time. And when I tried turn on phone there is only vibration and green flash on power button. What can I do? Plz help me, I have lost the warrant and I dont know is there any guarantee for my phone!
P.S: I've tried that repair thing in PC Companion and it says The phone contains modified software that cannot be updated.
Sorry for bad English.

Try Sony Ericsson Update Service - its a different software - google it or search for it on xda.

Did you have an unlocked bootloader?

If this doesn't work try flashing stock rom with flashtool.

Thanks a lot!
I love u guys that some flashtool worked!
But I have now that 4.0.A.2.368 and I want some normal updateble version like 4.0.2.A.0.42 Not any modified version. Do u know where I can get one?
thanks really, I thought that my phone was broken. I broke my last phone (ZTE Blade) and I didn't want to break this one.

If you need .42 i have it saved on my pc. Pm me and i'll send it to you. If you want to be able to update over the air you need to lock your bootloader again.

problem upgrade firmware xperia arc

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!

[Q] Sony Arc is not detecting the battery

I have Sony Arc LT15a. One night it died, I charged the phone and when I started it up it was stock in a boot loop only displaying the Sony Ericsson logo. I brought it to a phone repair guy. He, I assumed flashed it with new firmware which was LT15i. So it worked and boots up but now the phone no longer detects the battery. I have another Sony Arc and tested the cable and the battery.They both work fine on the other phone. I downloaded the flashtool 9.10.1 and a generic rom for North America 4.04 Ice cream sandwich. It flashed the phone and everything updated fine. The phone now says its Model LT15a, Android 4.0.4, build number 4.1.B.0.587, Kernel version 2.6.32.9-perf. The phone is still not connecting to the battery. So my question is this a firmware issue? or a physical issue with the phone? Any help, suggestion would be greatly appreciated. Thanks.

Did the repair guy flash the firmware?

I think that he flashed it since the phone went from being a LT15A to a LT15I. I was able to use the flashtool and get it back to a LT15A though. Do you think this might be a Firmware issue then?

It can be that he installed a older firware, that leads to battery issue.
If you got open bootloader try to flash a kernel with battery patch

Battery
So my phones boot loader is locked. Do you know of any threads that can give me a step by step how to replace my firm ware and kernal and or how to properly unlock the bootIoader? I have been looking at the jellybean firmware but it looks complicated to install. I am a total Noob and I am just getting lost looking at other links and treads?? Thank you

Try this

For another guide google "xperia arc testpoint"
Or you can google sony unlock and do it the official way. But you will lose drm.
I prefer the first, testpoint

[Q] How to upgrade from GB back to ICS? (Emma flashtool)

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
...
Sent from my Xperia Neo V using Tapatalk 2

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!

R800x Recognized in Flashtool as an R800i

Hello all, I don't know if these forums are still very active, but I'm in a pickle. I accidentally flashed an international version of a rom for my r800x and now in flashtool it is recognized as an r800i and is somewhat soft bricked/bootlooped.
I managed to get it working, but with all the frantic flashing ive been doing, I can't remember exactly which rom/kernel combination worked. I can still get into flashmode/fast boot, but it hangs on the Sony Ericsson bootscreen. I unlocked the bootloader, but just relocked it in an attempt to revive it If you have any tips for me that'd be greatly appreciated. Thanks!

I'm assuming that you have the Verizon R800x... If so, then you should be able to use Androxyde's Flashtool to flash the stock Verizon ftf to restore the phone back to stock. You can then root it with a couple different root methods (I prefer the Cydia Impactor Root method). You could also flash the Verizon stock 2.3.3 firmware back onto the phone and root with SuperOneClick/DooMLoRD's method.
Here's a link to the stock 2.3.4 firmware : https://www.androidfilehost.com/?fid=9390350787562963051
Here's where I got the stock 2.3.4 firmware from: http://forum.xda-developers.com/showpost.php?p=43935372&postcount=3
I'm not sure if you're using Sony's flashtool... If so, then I would recommend Androxyde's Flashtool from here: http://www.flashtool.net/index.php
If you're interested in rooting with the Cydia Impactor method, you can find info on it here:
