[Q] Phone doesnt start

Hello,
I'm using Arconium rom when i tryed to install the CM9 to test, well i just flashed with fastboot the new img from FX and install the rom. The instalation started but returned an error that i don't remember something about lt8i (my phone is lt5i).
I go to flashtool and tryed to get back to stock rom, but without sucess, now my phone show the Sony Ericsson logo and later it stay black.
Thinking i can fix this i relock the bootloader with flashtool files (found on Xperia Arc forum) and still not fix. Now i cannot unlock the bootloader "oem failed" and the phone doesnt start.
Please someone can help-me with a tutorial or something else ?

Take battery out, connect it to pc, press the back button and now plug in the battery again and see if it connects in flashmode then.

Wow seriously. So many people ask the same thing. Just use seus or flashtool
Lol you edited your post as I replied.
Are the driver's installed correctly on the pc?
Sent from my R800i using Tapatalk

I've used flashtool on this phone before when I installed DoomKernel. So everything is installed correctly.
Update: Got ahold of my original factory firmware, R800a. And flashtool sees it, just had to go fast enough for it not to reboot. We'll see if this fixes it.

Well got a stock firmware reinstalled, it overwrote DoomKernel. but oh well. got it rooted, reinstalled CWM, and restoring. Hope it works.
Update: Thank god it's working again.

Bricked ION.... need help

So, i have update my ion to ICS LT28h, my wife's ion we waited for the official AT&T update. I downloaded PC Companion, connected the phone, started the update process. I did all i was told on every screen. the phone never updated and now does not power on. no lights when plugged in to charge or connect.
help?

1) hold the power + volume down for like 15 secs...(untill you feel a vibrate)
2) download flashtool at http://androxyde.github.com/
-----Install
3) download whatever FTF you want at http://forum.xda-developers.com/showthread.php?t=1752345
----move it to C:\Flashtool\firmwares
make sure drivers are installed(find them in C:\Flashtool\drivers
4) Launch Flashtool
5)select the thunderbold
----select the ftf
6)insert the micro usb end into phone (leaving the regular usb out of computer)
----it will tell you some instructions on how to flash but they are for different xperia phone
7) while holding the volume down button while the phone is off (From step 1)
insert REGULAR usb into computer
it should say flashing, or your comp might say installing driver, or it might just say drivers not installed..
ONLY IF YOU CHOOSE TO INSTALL LT28H FTF--------------repeat this step but now install the file from (FOR LTE)

If it is an AT&T phone do you really want to update to LT28h?

why not install lt28h
all you have to do is just flash the extra ftf
and then just change the APN
which i as well as spectre have posted

No reason to use the LT28h anymore since the LT28i and LT28at both have ICS and root.

In hope that someone's still looking at this thread, here is my situation: I tried flashing a prerooted image via fastboot and landed in a Sony bootloop. Then somehow I was stuck in fastboot-mode (led: static blue) and let the phone drain its battery. Now I'm able to get into flashmode but when flashing the chinese FTF with the Flashtool it stops at 1% with status "Processing .......sin" (sorry don't know the file exactly).
When I'm trying to power it up now the Sony logo comes up followed by an exclamation mark in a triangle... could you tell me what options there are left? I saw these prerooted images (http://forum.xda-developers.com/showthread.php?t=1669906), but there is none for the Ion, so I don't know what could be the next step. If I just had back my normal system... I used to flash my Galaxy S many times so I'm not that unexperienced, but it seems I really have a problem here:crying:
Any help is appreciated!

What model are you working with? And where did you get this prerooted image (the one you tried to flash)? From the link you posted I don't see one for the ion. Anyway, based on my own soft brick experience, you'll prolly need to let the phone battery drain, then charge (process can take a day or so), then try and flash your stock FTF via Flashtool.

I have had the 1% happen to me. I just unplug phone close and reopen flashtool and try again. Took me 3 times to get to flash once.
If still no luck, like spectre51 said use repair option in pc companion.
If all else fails use this thread

Thx for your hints! It is kinda frustrating to wait until it is fully loaded, then try flashing, then load and wait again... but the 1%-bug seemed to be a major bug as it is fixed now in the new version 0.9.8 of the flashtool.IGonna tray again tomorrow and report my status. I already checked popfan's thread to get a point if mydevice really is bricked or not. So again thanks to all of you!
Just out of curiosity: is there a possibility to flash a prerooted ftf-file? I live in Switzerland where I bought the lt28h version. And I haven't found a prerooted. img file for flashing via fastboot. Just want to root it, custom roms etc. later

Alright, I was able to flash the chinese FTF and got my phone back working:laugh:
But I had to install the newest version 0.9.8 of the flashtool to not get the 1%-bug again. After this roooting via bin4ry's script worked well and now I'm happy happy happy. Thank you all!

I also had problems with flashtool 9.7. I used 9.0 with no problems. Didn't know about 9.8.

as the OP of this thread, thought i'd update. After reading a few threads i discovered the power/volume button trick. tried volume down with no luck, but power and volume up worked. PC Companion did not work in upgrading the phone. just kept telling me to disconnect my battery, and that if the batter cannot be disconnected to skip that step. But it wouldn't go to the next step. So I tried SUS. Worked perfectly.
So, My phone is running lt28h and my wife is on lt28at. There are some differences in the way data is downloaded. looking at my AT&T bill, the data downloads, i assume for apps that get updated, seem to be different sources. also my phone has significantly larger downloads even though we have similar apps. I do have a couple of weather apps she doesn't have that might be responsible for that.
I'd like to do some additional comparisons, but think i'll be flashing the AT&T rom on my phone soon.

[SOLVED] Arc stuck on boot logo stock rom, locked, unroot.

a friend has this phone, his children were playing games on the phone and suddenly the phone rebooted and since then the phone is stuck. It boots in to Sony and then Xperia, then a long vibration and back to loop of Sony logo.
It's not rooted, running on 4.04 stock, locked bootloader, and it's not even getting into recovery mode. Please help.
Thanks.

Hi,
Dis you try, "Sony Companion" or Flashtools" ?

Re: Arc stuck on boot logo stock rom, locked, unroot.
Thanks..
Not yet. I just got the phone and have tried getting into recovery.
I shall try the PC workout later in the evening after reaching home.
What do you suggest?
A reinstall of Rom via companion or flash tools?
Sent from my GT-I9100 using Tapatalk 2

First try PC Companion... and i was thinking... if it's not rooted how could you go into recovery mode.... i think it's impossible if you are not root...
So when the last rom will be installed by Pc Compagnion... Root it (flashtools and/or doomlord's method), install a recovery (like X-parts an app on market) and and like that you can do what you want with it...
Tell us if it works...
/////
Oh i see you have habs with samsung's or htc's phone... They have a recovery without root but not the sony's one...

Re: Arc stuck on boot logo stock rom, locked, unroot.
I just have one query...
How will flash tools or companion work when the device does not settles down, as it's in bootloop, from Sony logo to xperia logo, then a short vibration and sometimes a long one and screen goes blank and then Sony logo, and xperia logo, it's going on and on.
Please enlighten.
Thanks.

He was wrong when he said PC Companion, you need to use SEUS, Sony Ericsson Update Service.
僕のLT18iから送られてきた

You can use SEUS if it works yet but i'm not sure....
BUT you also can use PC COMPANION which works....
No need to turn on the phone, do you know "the flashmode" it's a basic.... so you can follow my tuto on my signature...
AND please follow exactly the steps before posting it doesn't work...
You can also try FLASHTOOLS...

phone back to life.. PC Companion worked in first shot..
thanks a million.

Trully happy for you... Now don't forget to write something like [SOLVED] in your title...
See ya...

what kernel you flash with the rom? did you flash the kernel modules

Stuck on SONY logo

Hey all,
Yesterday I was about to flash a new ROM on my wifes Xperia S. She had an old ICS rom and I decided to go for the PAC MAN JB 4.2.2 ROM. Seemed ok.
I own a SGS2 myself so I consider myself a total noob when it comes to the Sony.
I know CWM works on on the XS and I am pretty sure I installed it when I romed it last time. Although I didn't remember how to enter CWM mode so I installed it again through that .bat file that comes with it.
I downloaded the ROM and the GAPPS and copied both to the phone. And now I thought I was set and went for it. Of course I did a Nandroid backup before and also from within the phone a full backup in Backup & Restore. Bootloader is unlocked by the way.
So now I boot into CWM and I do a full wipe/factory reset. I clear the cache and dalvik and also I format the system as he guides us to do in his installation video.
I then installed the rom or at least tried. Got the status 7 together with some error I can't remember.
I read then that people had issues downloading the rom with google chrome which sounds pretty far fetched but I decided to do what other did and downloaded the rom from firefox.
Then within CWM I thought to start the USB and copy it directly in CWM since I already had reset the phone and didn't want to go through the "new phone" routine. But the USB in CWM didn't work so I had to restart the phone.
It then got stuck on the initial SONY logo screen and I'm stuck there now.
I have installed the Flash tool from SONY coz I read in another thread that the only way out is to install stock rom. However when I connect the phone holding volume down windows 8 always say that the USB device is not recognized. I have of course rebooted the PC after.
I'm going to try this on my Windows 7 PC as well later after work but I dread I will be stuck there as well.
Can anyone shed some light on how I can get my wifes Xperia S to be recognized by her Windows 8 laptop? Or have I bricked her phone?
I have thought many times that I bricked my SGS2 but always came out on top, I don't want to lose this battle either.

if it says "Unknown Devices" when you plug the phone to the computer, try change an USB line or change a computer
if it says "Unable to install the driver" or another something like this when you plug the phone to the computer, try install the Flashtool driver
...any screenshots?

Windows 8 gives a balloon tip saying exactly "USB Device not recognized". And I did install the Flashtool to get the driver but I guess I still miss the correct driver here.
I will do some more troubleshooting after work. I just thought maybe someone had similar problem and had a quick and easy solution.

It also happend to me, just turn it off and flash stock firmware with flashtool (select all under wipe)

The issue is not actually the "stuck on SONY logo". The issue is that the computer wont recognize the phone when I connect through USB.
What did you use to get the correct driver?

Ok I actually managed to get it connected on my Windows 7 PC.
I installed Emma (Flashtool) and it installed something but I'm not sure really what happened to be honest. Light on the phone was green and it installed 4.0.4 ICS.
It was a success after about 217 seconds but after that the phone didn't do anything. Stayed with green light and when I disconnected it it could not be started at all.
Maybe it doesn't have enough power to start up. It is on 220V charge now so lets see what will happen with it.

Good news y'all.
All it needed after using Emma was some juice. Now it is back to it's normal self. And I'm not going to ROM it anymore. Soon JB will be officially out for XS.

True!! When I was a noob, I tried to flash cyanogrnmod on my galaxy ace (it was a year ago) and I stuck in bootloop. Idk what to do and I regret it, from that day I never flash any rom. But this year I flash xzxperience on acro s and it works but not so happy and then I flash stock firmware to normal. And I regret because i ve unlocked bootloader!! And now BE is not working anymore.
