Pressing once does not turn it on. You need to hold it down for few seconds, til it vibrates. Then you can release it.

I do this but wont power on. I dont know why.
Its recognized on my computer as qualcomm usb or zeus flash device.

It's soft bricked, you need to recover your phone with Sony Update Service.

You won't need to power on your phone for this. Install Sony Update Service on your computer and follow the instructions given.

To turn off phone, take out battery (just to be sure)
Put battery back in.

Press and hold back button first. Dont release
Now connect cable.
Should work now and update service will do its stuff.

Thank you guys but
It work, green led and updates loading, phone detected as s1boot download.
I unplug the phone and hold power button until vibrate but nothing
Now when I plug phone on the pc, the computer detect qhsusb_dload device

That is strange. I am running out of ideas to help.
Last idea is to use Flashtool and flash a stock GB/ICS rom.

Ok thank You

[Q] Xperia Arc S Lt18 died after flash boot.img

Hey buddies,
I have a big issue:
My Xperia arc S is rooted, I did the bootloader unlock with sucess, and, when I flashed the boot.img (I had sucess by ADB), after ask to "fastboot reboot' my device died :/
It can't be recognized anywhere (USB-PC, wall charger, vol up + usb but it doesn't enter in fastboot mode), it doesn't turn on anymore.. When I hold "power button + vol up + vol down + camera button it's vibrate, but nothing happened in display. I had just this feedback.
Any ideas?
Thank you!

Try using flashtool. Hold down "menu" key and plug your phone into the usb. You will get into fastboot mode and then flash custom kernel.
After flashing kernel get into CWM recovery. Once you get in there its easy to install the ROM you want.
Make sure you flash kernel according to the ROM you selected or else you will get bootloop.
CHEERS!!

same issue

No, you don't need to press power button.
Switch off your device(which is already in your case) then while holding down the "menu" button on your phone, plug the phone into your computer via USB cable. If blue LED lights up, means you have successfully placed your phone in fastboot mode.
If its not working then probably your device battery is empty. You will need to charge it bro. And this might be a big problem unless you have got one more arc/arc s.

Sounds like the chargemon has been corupted of wiped! That could explain the charging issue. Try vol down & plug in usb for flash mode(green led if good) connect to pc companion and repair phone, or flashtool and the rom of your choice. If not it may be a jtag job im afraid n thats pricey!!!

Use the Rubber Band Trick.

like how many hours?

All you need to do is hold power and volume+ until the phone vibrates 3 times. Then open PC Companion and do the repair phone procedure, and follow instructions. Your phone isn't bricked, you just damaged the OS and now it can't start anymore.
If you have CWM Recovery you should simply reinstall your rom from a flashable zip.

i tried the rubber band trick for about 16 hours nothing happened just RED led light. (
@MarkMRL- my pc companion does not recognize my phone. i pressed the POWER and VOLUME UP nothing happens. What will i do?
I have SUPERSU. i didn't intall any rom on my phone. i just followed easy rooting toolkit by DOOMLORD.
METHOD 2. (( Please help me. Thankyou:angel:

Note that chainfire 3d will cause bootloop on ics and jb os, its for gingerbread

try reflashing the stock rom with SUS instead

if all else fails.... take the phone apart.. disconnect the battery from the motherboard.... start flash tool and have your file ready to flash... with usb plugged into phone... .... connect the other end to the computer... hold the volume down button.... plug battery cable back into mother board. NOTE: you should already have flashtool running and the screen telling you to plug in your usb... If it doesnt work the first time... try again.
I know this is something you don't really want to do... but the other tricks and tips did not work for me... this is what i did and i got it running again.

Why are you guys suggesting such invasive methods of repair that will make him risk breaking his phone completely?
He isn't doing the standard PCC repair procedure right, maybe because he's nervous and has been confused by your insane suggestions.
You need to do this:
1. As the phone is bootlooping, hold VOLUME UP and POWER for a few seconds until the phone vibrates 3 TIMES
2. Phone is now turned off DO NOT CONNECT IT TO PC, open Sony PCC, click on "Support Zone", click on "update phone", a window will inform you that there is no phone connected, in that window, click REPAIR PHONE
3. Follow instructions
4. This is important, when it tells you to connect the phone, do exactly what it says: HOLD VOLUME DOWN AND WHILE HOLDING THAT BUTTON CONNECT THE CABLE. If you did it right, the phone will light the notification led in the color GREEN
5. PCC will install drivers if needed, and then reflash your phone with stock FW (you will lose all your data except SDcard/internal memory contents, such as photos and videos)
If you want to try and recover the phone without losing data, you need to download an FTF of your current rom, and flash the phone with Flashtool instead. Before flashing, after selecting the ftf, you need to deselect "Wipe Data". When it asks you to connect the phone, do what I said in point 4, not what flashtool tells you to do.
Remember to instal CWM and make a backup before installing risky programs.

Bricked - Help Needed!

So I got my brand new Z1C today and as you would do I rooted, backed up my TA and unlocked the bootloader. I also flashed on fastboot DooMLoRD kernel to get cwm.
I saw a new stock update for for 4.4.4 so I decided to try update via Sony PC Companion. Update downloaded but I was prompted that I could continue due to 'modified software'. So I decided to restore my TA to bring it back to stock and phone doesn' turn on
When I press the power button it vibrates but there is no display. If I wait a few seconds and press the power button it does the same. I can also still boot into fastboot mode. I attempted to flash a .ftf but I can't seem to get it into flashmode :crying:
Would anyone be able to help please?

Ha, that happened to me as well when I tried to restore the dreaded TA. But if fastboot is working, flashmode should too. Turn off the phone, press volume down and plugin usb. Iirc there's no LED confirmation in flashmode, but you'll see it in flashtool.

Flashmode managed to work! Phone seems operational now.
Deary me that was a bit worrying. Is it quite normal for you to have to flash a .ftf after restoring the TA or something? Nearly crapped myself...

There is an LED confirmation for flashmode, a shortly powered green LED. Fastboot is indicated by a solid blue LED.

You've done correctly, but you've missed one step, before flashing your locked TA and rebooting you have to flash a stock kernel, otherwise the "modified software" test in the locked bootloader will be triggered (by the unsigned kernel).
You have not bricked your phone, this thread is incorrectly titled as I'm sure you knew when you posted it.

How to reboot Xperia S

Hey, i have installed TWRP recovery. It works, i can get to it and make backup etc. But how I can power on my phone? Really, I have no idea. Normally I should just push Power On button, and it will work. Now it doesn't. Phone is restarting all the time to sony logos, then pink led, then blue and power off. Then after few second phone is restarting again and again. How I can just normally power on my phone?

Please tell all the things you did before the problem begins. What have you did last thing to your device? Put your device on charger until your led turns green.Then flash official firmware by flash tool.
Another thing do you able to boot to twrp recovery?

So i have unlocked bootloader (but like 2 months ago) and installed twrp recovery. Actually now, since the battery decharged, because it was restarting all the time, i can do ****. I can't put it on charger, because its restarting after like 5-10 minutes after charging. I can't flash my phone, because its decharged or its stucked on sony logo. I can't use the official repair tool, because its not recognizing my phone. Now I can't even get to the recovery.

ok calm down.Its not a big problem.Just follow these steps.
1. while you see sony logo or when the phone is turning on ( Press and hold VOLUME UP key+POWER key simultaneously).While you feel a short vibrate release the keys. Now put on charger.hope you will not get the automatic turning on problem.
2. Then Download Flashtool software from internet. ( official repair tool will not work coz you have unlocked your boot loader)
3. Download your mobiles official stock firmwire.Then flash it using flash tool.
You can learn about flashing ftf(firmware files) by flashtool from internet.
Best of luck

Ill try to do that 1 step, but I think it wont work. And I have already googled those next steps. Anyway thanks for those steps

Yep, nothing actually works. I get the sony logo, start pressing power button and volume up, then green led is lighting. Its fine for like 5-10 seconds, then its decharged, need to charge for like 20 seconds, and then again sony logos appear. Infinite loop.

The green light means you are on flash mode.the mode is used to flash firmwires.so you need to install flashtool.then install flash mode drivers.then do the steps to flash firmware.

But I can't install anything, since the xperia just restarts after few seconds or just power off, because I can't charge the battery.

You have to install flashtool and drivers on your PC.search on google guide to use flashtool

I have installed drivers and flashtool, but man. You don't understand me. The phone is not charging when im in flash mode. And I can't charge it, because the screen with sony logo can't be powered off. I can only go to flash mode, but in this mode, phone is not being charged. And if I try to flash firmware the phone just run out of battery.

1. R u able to power off your device by volume and power key?
2.OK you can flash stock kernel by fastboot mode.it can be done with a low battery.(may be you have a corrupt kernel)so after flashing kernel you can try to turn off your device by pressing and holding vol up +power key.don't let go any of these two buttons until you get a vibrate.I have never listen or faced this type of issue where we can turn off our device.

You can also try doomlords kernel.it has recovery included.

Best way is to go to a mobile shop and ask him to remove the battery by unscrewing. You can try at home to do that if u have tools to unscrew

Do You still have a working recovery? If yes, then You can push a ROM zip to phone via adb while being in TWRP and then flash it. Also, again if You have working TWRP, You can turn off phone via it by going in TWRP>Reboot>Power Off.
You can also turn off Your phone by pressing Power and Volume Up button together. You will first get a single vibration. Keep the combination pressed, then You will get three vibrations. Now Your phone will be turned off fully. This combination will work.
Whenever You connect Your phone to PC/Charger, Your phone will charge, regardless it's in bootloop or not.

But, can you read? I said i cant get to fastboot, cant power off phone, cant acces twrp.

You are asking for help and mirhawk is trying to help you.you should not write him like that.if he didn't read your previous post then you can tell that politely. If you behave like this then no body will help you.XDA teaches us to be friendly with all first.

xDD He should spend 2 min of his life to read the topic instead of writing useless posts. Anyway, phone is dead, there is nothing you can do actually or its not even worth. Close topic.
