[Q] Xperia Arc not turning on anymore

I just received an OTA to my Xperia Arc. The update downloaded fine and it started the update OK. During the update (I had the open box icon an 4 dots on screen) the phone just shut down and now it doesn't turn on anymore... Nothing happens if I press power button (it doesn't matter how long) even after removing battery.
Is there anything I can do. Is my phone permanently bricked? I thought they test these OTAs before pushing them out?

Let me guess, your bootloader is unlocked?
If yes, go to the Android Development section and flash the unbrick thing for fota bricked devices.

Flo95, yes. My bootloader is unlocked. I thought the OTAs would still work.
Thank you very much for pointing me towards a solution. Well appreciated!

@Leafhill,
Unfortunately, if you do have your bootloader unlocked, doing an update OTA ends up bricking your phone.

Hello Flo95 i have exactly the same problem of Leafhill i was updating the xperia arc and the phone just shut down and now it doesn't turn on anymore, Nothing happens if I press power button even if i remove the battery. i have flashed around 7 times with other firmwares and still nothing, i read your answer but i don't know hot to use the flash of the Android Development, can you give me some advice plz? thks in advanced

Same problem here. But the bootloader is locked. So how to get it on now?

Is you bootloader unlocked??
What ROM or Kernel do you use?

i received an update notification when i using wifi..then i just download it and install..next it turns off automatically..after a few minutes it doesnt on.. ( i think the notification is from ''update center'' or something like that.. )

Thats a shame...updating via OTA should'nt be used if you unlock bootloader...
Now...try to flash ROM and Kernel via Flashtool..

It'll most probably be fine don't worry - this has happened to many of us! Have a read about flashtool etc and you'll know what to do next time.

no man i didn't unlock the bootloader,i can't do it with flashtool

Sony now has the ability to give out unlock codes for the Play, if my memory serves. You may want to try it. It will break any warranty you have, so be aware of that.

If you didnt unlock your bootloader before installing a custom rom. Idk how else to help you. You might have to send off your xperia play to Sony.

i have bricked my phone several times and im a pro at fixing them too! lol

Yes use his flashtool. But the real question can you use it if your bootloader is locked.

works on both
If a boot loader is locked it means its intact hense the word locked. So the phone boots so all you have to do is..
Download your stock ftf file for you phone.
Hold the back button when you connect your phone and flash your firmware back. Light should turn green.
If it don't hold the power button while you connect it Sonay used this method to put it in the first time.i

Hi
I was hoping you could help me. I rooted my play and was following a youtube video as descibed. I couldn't attach the link because I am a new member. It was the new ics 4.0.4 from the android doctor - 100% bug free gaming rom. I had difficulty in flash tools when i needed to go into fastboot mode to install the Lupus kernel. So I installed the cwm mode from the internet and tried to install the ics from its recovery mode. Now I just get the sony logo, then the screen goes black. It is still on. I have reinstalled flashtools and have seen some stock roms on this site to download. The problem I have is when I select the rom to flash, whilst it recognises that my phone is in flash mode, I get a error flash cancelled. I have tried 3 different stock roms. I am in the process of downloading Emma - a flashtool from Sony. Hopefully my phone is not screwed. It was on 2.3.4. One week old unlocked rx800i. Any help would be appreciated.
Thanks..
Tommy

You guys remember about 2011 June, a problem came up with unlocked bootloader and OTA update. the first fix that came out broke the radio rom or something so your phone won't accept any sim but will boot and be like a psp or media player. well. that happened to me. and 2 years down the line, i'm still with my play hoping someone could come up with a solution for that.
boots up fine. plays games and audio video no probs but still can't accept any sim in it.
Specs are as follows
model R800i
android version 2.3.4
baseband number 8x55A-AAABQMAZM-203028D-56
Kernel Version 2.6.32.9-perf
[email protected] #1
Build Number 4.0.2.A.0.42

What is "dead boot"?
Does phone vibrate when powered on?
Any lights on led?
What happened when you plug it PC? (nothing, something...)
What happened when you press search or back and plug it in pc?
What is your model? i,a,at,x?
How your phone died in first place?
Do you have locked/unlocked bootloader?
What was latest firmware/rom installed on phone?
did you overclock it before it died?
If you just saying "help me, my Play is dead" and not providing any info, then no one will be able to help you. Even worse, no one will be willing to even bother asking questions that you should say in first place...
And yes, one of reason your Play don't work is that motherboard is dead, so no one can help you. Just be ready for that answer even if you don't like it

Well, good news, you Play is not tottaly dead (green light means battery is charging and full)
Do you have drivers installed for phone?
-Try the following:
press and hold back button and while keeping it press connect usb to PC. Now right click on "my computer" and choose "manage". click on "device manager". Do you see anything named "sony" there. What exactly does it say? (something like sa102, unknown,etc...)
-Did you try to flash stock firmware with flashtool?
Guide where to download and use it can be found in thread [GUIDE][18th Dec][4Noobs] Flashing A FTF File Using Flashtool
And you can download firmware from Xperia Play Index - ROM'S, FIRMWARE, KERNEL'S, GUIDE'S, THEMES, MOD'S second post, choose file named R800i_4.0.2.A.0.79.ftf
-Did you tried to repair with PC companion?
You can download it from Sony's site
-Did you tried repair with Sony update service?
You can find it here

yes i tried to flash stock firmware.. its says that its finish that i unplug my phone and then open it.. but still only vibrates..

Hm, if PC Companion don't work, try Sony's Emma Software
But i am in doubt that you can repair it yourself if Emma doesn't work

It is not impossible, but as i said, for you could be very difficult (since you don't know much about Play's hardware and it's probelms)
As FaiselW said, try also to relock bootloader.
Bricking is common fault when doing OTA update on unlocked bootloader
Check this thread also, it might help you

Search around the forum, there's plenty of tutorials out there. Also do some research before you do anything to your phone. Don't try it if you cannot understand the instructions.

At sony's logo?
Then you dont have an unlock bootloader, and you can't install any CM based ROM.
Use the pc companion or whatever software recommended on those tutorials to flash an original firmware form sony and bring "back to life" your phone. I don't know if you need to root your phone again (it disappear)

Thanks guys flashing it worked...just needed to wipe cache thanks
