Bricked phone

I was having trouble rooting my phone so I tried flashing a kernel that wasn't for Xperia Arc. Now when I try turning the phone on the two lights beside the home button shine and nothing appears on the screen. In Flash Tools when I plug in the phone nothing happens and the log has

The button lights working that means your phone is not bricked.
Just repair your phone with pc companion.

It gives me the message "Sony Update Engine doesn't have software for your phone."

I tried Flash Tools again and this time I got it to work and Flashed a proper kernel. Maybe I got confused last time since the screen didn't turn on and thought the phone was off when it was on.

[Q] Xperia Ion LT28AT - Am i missing something

Hello their I have a problem with my xperia ion (obviously) I have soft bricked my phone, So heres the story .... i backed up my phone 2 days ago just incase lol . i installed CWM for xperia ion just incase aswell before i installed an app so i can change my fonts and boot animation on my xperia ion. I downloaded and use "Rom Toolbox Pro" and from their on i use the "Boot Animations" app to change the original At&t startup to the Razr M bootup. and after i restarted it , it worked just fine. Then after i went back to the app and went to the Font installer i backed it up as well as my boot animation. I installed a certain font i think it was " " after i restarted the phone , again, it worked perfectly fine , then after a couple uses of the font i got tired of it so i went and hit restore , i didnt know what i was really doing from their. a menu popped up with all these things checked so i went ahead and clicked ok, and it said to restart , so then i did. After it was restarting , upon booting up it would just shutoff or shutdown or do this fading away power off thing as it finished the boot animation. After the third time i did the " soft reset trick" and it still happened again, but by mistakenly doing a ":hard reset trick I think " it just completely vibrated 3 times instead of 1 not realizing and it shutoff. nothing was happened i pressed a few buttons but it still didnt budge. and i read online that to let it die while plugged in to the factory WALL charger. so then i did that.......after a few 15-16 hrs i had a constant red LED light come on and then after another few 2-3 hours there was this red LED blinking i guess? it was as if it was trying to turn on or something. but all i saw was the screen come one but nothing showing and the LED staying on for a few then going out .....so as of right now it stopped doing that. and its now at a constant RED LED LIGHT nothing else. i dont what else to do. i have my Flashtool already good to go with the stock f/w ready to wipe data /cache and everything i guess.
and what did i do that ruined the phone?
How long should it take?
will it change led colors so i can flash it?
so what do i do for now?
edit- my phone has a locked bootloader so I cant use the fastboot method only flashmode method. before when i pressed the power button i would see a red led and then it look like it tried to start , the screen came on but it was pitch black and then it stopped and what it seemed to be that it restarted and it kept doing that. I guess the backlit on& off then repeat and then to Constant RED LED. i only did the soft reset where i jheld the power and volume button and it vibrated 1 time. , it didnt even scan the phone or detect as i connected it to my computer, i can only do the flash mode method only. manually i guess......
Red LED turned on, after a second the screens turns on (just black) for 1 second, red led turns off like screen and 2 seconds red LED is on again and the same start again (with screen and so on). the rubber band is holding down the volume down button. so as of now i started flashtool, flashmode, selected the firmware and when it asked me to plug the phone in, the phones already plugged in, but right Now the computer doesnt detect the phone at all, no sound , no pop nothing in device manager, but its continuing with from the beginning (blinking screen and red LED).......its removed and connected my wall charger and im going to wait overnight for this attempt.
edit- 2 its been a few days im still going with the process of trying to flash my phone through flashtool. I had to keep repeating steps like charge my phone, until the red led goes away and then plugging it into my laptop after a few 0-15 minutes my laptop detects it and it trys to install driver when I already have them installed I guess from Pccampanion and flashtool drivers aswell.

GOD NEWS TODAY!!!!! i let it charge on my laptop and it was at red , so i put flashtool on un plugged my phone ( rubberband was still on it) and when it a pop said to connect it, i plugged in the phone nothing happened after about i guess an hour or 2 i heard a sound and flashtool read the phone and my comptuer tried to install a "SEMC Driver" or something.
but i forgot i had two flashtools installed just in case......... i used the old on 9.1 and i didnt installed drivers dammit ..... im using 9.13 which has it installed

Hi.....I was wondering where you found the flashtool for xperia ion lt28at. I downloaded a flashtool but its for x8, x10, x10 mini and others but not ion lt28at.

Yep
---------- Post added at 11:02 PM ---------- Previous post was at 10:13 PM ----------
Just went through this myself, install the drivers from flashtool, bottom two.(no worry of our device not being in list) then restart computer, mine was boot looping on Sony screen ..that's what you want you are close, rubber band around volume down,plug into rear USB port if possible, flash tool with gingerbread ftf loaded and hit flash and just wait every ten minutes mine would loop but eventually green led hit and started flashing. I was on xp couldn't do anything with 8.1, rogers jellybean took 12 minutes to flash and u only have ten minutes before phone starts charging and shuts off giving error in flash tool.... tried stock att and rogers just didn't have enough time and they failed to flash, ginger was just enough time. Just don't hold volume down for three vibrations again if anything one is all that's needed. Patience and use gingerbread ftf. All you want is it running then flash whatever you want.

(HELP) Xperia ion bricked urgent help needed

Hey Guys..Yesterday I was mooving on from existen z to new chinese rom ported by me..But my bad luck ****s I accidentally pressed pushe via adb in cwm and after that what I did is I format the system ,wipe cache and dalvik cache and install the rom...immediately after installation is completed my cell rebot itself and got bootloop continuously ..Then I tried to switch of my android holding vol up and power ..for the first time I wait for one vibration ..it didn't work bootlop didn't stop and again I pressed volup and power and waited upto 5 vibration ..then mobile switched up and never respond again..no led on chrging ..totally blackout..Neither I could enter flashmode nor fast boot..
Then I kept plugging on wall charger whole night and red led light was appeared ..and left the whole day charging on red led but I cant able to enter the flash mode neither fastboot..Something strange is happening now..the red light will disappear and agin the bootloop will starts with sonylogo..when I hold the power button and volup key untill one vibration..the bootloop disappear suddenly and the red light will golw up agin..this process is repeating again and again..so guys please help me ....:crying::crying::crying::crying::crying:
@Toledo_JAB @pharix @funky0308 @Zorbeyd hey xda legends plz help me ...any suggestion would be much appreciated..

Can you disassemble the phone? If yes disassemble the phone and remove battery connector and connect it again. As soon as you connect it, enter flash mode and flash stock ftf using flashtool.

Disassemble is the certain solve for this problem. If you watch videos carefully, you wont get problem.
And.. Did you use rubber trick for enter flash mode?

yah I did ..But instead of goin flash mode the cell phone start bootlooping again..The strange thing is ..the soft reset doesnot remove the bootloop but the hard reset removes and while plugging on charger for some hour red led appear and again the bootloop starts aafter some hours..:crying:

@pharix bro..today I disassemble my cell and remove the power chip and reconnect again..I put in wall charger...;again the same thing boot loop starts when cell is charge for some hours and when battery is drained mobile get off and show red led when connected in charger..and During bootloop I accidentally entered fast boot mode but it doesnot make sense as I have relocked my bootloader..After that I am stuck in this blue led..Whall shll I do??? Is my mobile tolally damaged?? And during disassembling..I damaged my case..:crying::crying::crying:
Editnce I entered the flash mode via rubber band trick..but flashing files was initiated but ..there was error ..saying mobile doesnot follow the command or something like that..Wondrin yy my battery doesnot get charged..Is it normal that I am getting bootloop stil after removing the powerchip?? Now I am loosing hope.. @Zorbeyd bro..what do you say regarding this?? hepl please..
Here I have provided flashtool log..

Try this. Remove battery connector while your ready to enter flash mode. Again reconnect battery connector and soon enter flash mode and flash stock ftf.
Or once you are in fastboot mode, flash stock kernel and system separately.

Dont lost you hope,
Try with another usb port with another usb cable.

Flashing a kernel with bootloader locked was a silly thing to do. From what I can see, you are using another devices kernel, or the kernel itself is corrupt. Flashtool couldn't flash the ftf because you were in fastboot, not flashmode (volume button down I think. Flash mode has green led) What I can recommend is that if you're able to enter fastboot mode again, get the stock kernel and flash it. If you can enter flashmode, just flash the whole ftf.

The stock kernel or a derivative of it should be available in the development section. Or try to extract the kernel.elf from the ftf. A tutorial for flashing a kernel is available in the general section I presume.

acro s hard bricked

i got my acro s hard bricked
I used twrp for making a backup for the the stock firmware.
and then i installed the 5.0.1 the lollipop custom firmware
the link :http://forum.xda-developers.com/showthread.php?t=2799765
, but it was not rooted but somehow the recovery was working good .. i decided to restore the stock using the backup version which i made in the beginning coz the ROM was sucks. after finishing the loading it asked for restart and after that i got a blank screen and the following
-no response for charging
-no LED lights at all
-non of any combinations working (volume+ and power on , hard reset or volume+up+power on)
-access to fastboot or flashtool is denied
-no power on no vibrations
but after a day of charging an Orange LED appears but i waited for two more days till the LED disappeared
and tried the flashtool but all i got is "device connected but with debugging off"
i think the problem was using recovery with unrooted device but can't find a solution for that
any suggestions ??!!
Notes:
am too calm
am not panic ..
am not in hurry too
and it's not a big deal
i just want the device back in order to get my stuff from it that's why going to Sony service center is not an option coz they format the whole device

Similar here on st26i
On 4.4 Paranoidandroid I've got after a five days of use in one second a lot of force closes. From every app from the system. It was impossible to stop it, or make normal reboot, so I've hold Power + VolUp and waited till three vibrations. Then turn on the phone, normal vibration and SONY logo.
After that black screen. First with some backlight, after minutes phone backlight turn off.
Now:
- No response for Power button
- No response for Power+VolUp combination
- No charging LED
- System find only SEMC Flash Device
- Flashtool says Device Connected with USB Debugging off
- Combination Power+VolUp make connected device to disconnect and connect again as SEMC Flash Device
- Cant acces fastboot, dwonload mode.

it seems like we stuck here

Yup.
Is there any windows/linux software for SONY devices like KDZ for LG phones? Which have an emergency flash option and, etc.???
/EDIT
So... I have read a little and I think (wchich I supposed before witout reading) boot is "dead".
I think it will be possibly to flash new boot with s1boot, but. I cannot find service manual for lt26i. Can anyone have it? Or can say where is the Test Point in this device?

Same situation, really need help from someone because its my only android phone right now.

[Q] Black screen, no boot, help !

Hello
3 days ago I did root my Z1 compact, everything was ok, I did backup TA etc.
I didn't unlock bootloader, just root by downgrading kernel and then restoring last.
Phone worked for 3 days, without any problems and then turned off while browsing web.
It seems like batery is drained but it's not. I tried charging it but doesn't help.
When connected to pc, pressing power on and vol -, newest flashtool shows:
08/021/2015 00:21:54 - INFO - Device connected with USB debugging off
08/021/2015 00:21:54 - INFO - For 2011 devices line, be sure you are not in MTP mode

Any chance of unbrick ?

Just flash stock rom in flashtool. I think if this work.

It's was not detected propertly in flashtool and doesn't boot.
RESOLVED PROBLEM:
After 2 days of fail unbricking phone (via flashtool, pc companion and all other stuff) I decided to send phone on warranty, while I been packaging everythin I did push power button and phone start like it should. After boot battery was 56%.
Anyone can explain me what happend ?
I had feeling like rooting and mods caused data corruption and broke bootloader. I was wrong !
Maybe downgrading kernel to older version caused some battery calibration problems ?
I been charging phone for 15 hours and no success.

hEllo I got same problem but with different way , i hope somebody can help me, this is very bad for me, screen off and i cant go to recovery, can someone please tell me how to flash from flashtool without get error, because i see that with flashtool you can only flash if debug is active, and i cannot active !! because no screen ....help please

I've got the exact same problem.
Rooted 2 days ago.
While at work my battery went empty, so i charged it for about 2 hours when i got home. Red charge LED was on while charging. When pressing powerbutton nothing happened at all. Pulled it from the charger, pressed powerbutton agian and got no reaction what so ever. Pressed red "off" button and got 3 vibrations, then nothing. Now the charge LED doesent light up when plugged to wall charger. Cant enter fastboot og flashmode.
Very open to suggestions at this moment.

Press Vol+ and Powerbutton for a few seconds (it is like taking the battery out of the device). The phone should vibrate three times.
Then try to restart it.

Tried all different button combos, then let it sit in the charger while i booted up my good old Samsung S1. After a total time of 4 hours plugged in the Z1c suddenly gave life and bootet indicated 1% battery and charging. Very strange considering the red LED was indicating a charge the two hours before it went in to "coma".
Sometimes it seems like these devices have moods and feelings, haha.
Bottom line: My device is now working and charging. Backing everything up now so i dont have to panic if it should occur again.
