[Q] Help please ,phone won't turn on

I updated my phone (Xperia PLAY) from Android 2.3.3 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.
Locked bootloader.

But my ARC don't unlock bootloader And I still warranty
And my Arc not power on only vibrate

try flashing a .62 build if your phone is on .42 build (or reverse) that would reset your phone to stock
if that doesnt work, then search your problem on XDA

Someone has experience about this ? Pls help

Can someone help ?

better show it to sony service center if it is still under warranty

Try flashing the Stock ICS, if that doesn't work then you'll know if your phone has a serious issue.

I have a similar issue. Are you using the MicroSD card that came with the phone? I have suspicions on using different flash memory cards. Testing that theory for a few days with JJ Hybrid 3.1 ROM. If it does not hang for a few days I will put my 32GB Samsung card back in and see if it hangs again.

[Q] No Boot

Just to say that this is my first post on the ENTIRE FORUMS :laugh:. Hopefully I'll get to meet some of the devs on here as well as the normal community users .
Previously, I had a Xperia Neo port of ICS on my Xperia Play- it worked perfectly fine but was pretty laggy, so I decided to downgrade to the original Gingerbread OS.
The downgrade (via Flashtool) worked perfectly and the problems only started after an OTA (Over The Air) update arrived. I clicked 'Update', it went through the normal shutdown and install stages but never booted back up. After this, I could only get into flashmode and not fastboot mode so I could not simply reflash the boot.img to make it boot again. I went back into Flashtool and reflashed the firmware that I used to downgrade with, and it didn't work and the phone stayed off.
I did some research on this and apparently the OTA update stops the phone from booting if it's rooted, it linked to a patch (.ftf firmware) that said it will solve the problem but will relock the bootloader (and unroot it, replacing the DRM files so it will boot). After this, the phone does not vibrate when the power button is pressed, it just flashes the LED red three times. I've tried flashing different firmwares and now the flashmode cuts out (usually in the middle of flashing system.sin- don't know if this might be the result of a corrupted partition) AND to top that I can only get it to flashmode if I keep the battery out for a little while between flashes, it never goes to flashmode by unplugging the USB and plugging it back in again.
What I want to ask is, because the bootloader is locked again, Sony can't detect that it's been rooted once before, right? Also, because of the suspected corrupted partition, Sony can't access any logs and should just replace the phone under warranty (it's a year old next month), right?
Sorry for the n00bz questions, I just don't want to send it to Sony (It's already been booked in for a repair) and they reply that the warranty isn't valid because they somehow found out that it's been rooted once before- it costs £10 for them to send it back:victory:!

UPDATE:
If I leave the phone plugged in, it sometimes tries to boot (Sony Ericsson logo comes onto the screen) but a phone and an exclamation mark comes on the screen. After five seconds or so, the phone reboots.

Sounds like your battery is dead

Yeah... could be. It was on something like 20% when I flashed it back to Gingerbread yesterday and it wasn't on charge during the update so it might have lost charge which in turn failed the update.
Will report back when I've charged it up a bit (half an hour should get it to around 30%).

It now stays on the flashmode which is a good sign- thanks for the battery tip !
However, it's still not booting and it's not going to the screen with the phone and exclamation mark since I tried to flash with the R800x firmware. I'm giving myself until around 11:00AM tomorrow otherwise I'm putting the normal default firmware on it and sending it in for repair.

Reflash a ftf file or update using seus if you got a locked bootloader (I suppose you don't have already), that works for me when I got exclamation mark too.

try re-lock youre bootloader alreasy?
i attach the ftf file, after that repair youre phone using pc companion.
i hope it helps you boot again
EDIT:
Please refer to this tutorial where i got it
[Tutorial] Relock bootloader!

Thanks all for helping- it seemed to be a battery issue here where I think something made the battery drain really quickly.
I didn't make anything better when the battery cut out when it was flashing half way- I think this might of been the reason for the phone with the exclamation mark.
I let it charge for a bit and was really surprised when I saw 'Sony Ericsson' on the screen and even more so when the boot animation came up!
It's now been reflashed with Doomkernel and GTA finally works great on it at 1.4GHZ .
Thanks to you all for your suggestions- really appreciated .

[Q] Xperia SL JB issue?

So a couple of weeks ago i updated my SL to the official (and latest) sony JB 4.1.2, it was working great until a a few days ago when i was watching youtube videos at night, when i put my phone away i had the wifi on and woke up in the morning to find it dead, i did not worry and simply put it on charge on a wall socket, i've had this thing happening to me ever since i was on ICS, nut after a while i checked to see if the phone was charging but to my surprise it gave ABSOLUTELY no signs of life.I've had it charging for 4+ days now but am getting absolutely no LED responses or any other responses of any sort,I've tried force restarting it and a couple other tricks but am still getting NO response.
additional info: im rooted w/ CWM recovery, my bootloader is LOCKED and apart from this i have made NO modifications to the phone

Thank you to anyone who can help solve my problem!

Try to connect to pc with flashtool open look if it find your device...
Maybe you can flash a ftf of stock jelly bean

Sorry, PC doesn't detect my phone!

Bricked to hell, hoping for help

Hi everyone. My xperia was flashed with a stock kernel from another model in attempt to recover from a bootloop trying to install TrueAncestor GB Edition. My model is a R800at, but I had assumed it was the global model since it came in xperia packaging and not ATT pakcaging . So I flashed the rom and I thought it would work but it bootlooped. Tried lots of kernels and landed on a R800i stock kernel, which has now made my phone unable to flashmode, fastboot, or even turn on . No red LED of doom, but when I plug my phone in it makes the low pitch USB noise rather than the normal noise. I've tried my best and this is the only phone I've got for around a month when I'd be paid enough for a replacement if this is unrecoverable. Unfortunately, this means I am unable to receive contact from work, friends, family, etc. If anyone can help me you don't know how much I would appreciate it. Thanks for reading and I hope you geniuses can help this poor idiot who thought he could be a rom flashing master. :crying:
