Hi Guys,

I have an Xperia T with an unlocked bootloader that was flashed with a Kernel, phone seemed to crash and then went to sleep and wasn't able to turn on. There was nothing, no LED or anything on the screen and acted dead.

Had it on charge over night and noticed that for a short while (possibly 1 minute?) a red LED came on that was not blinking, just static and then went off.

I have unplugged the phone from the wall charger and tried to reset the phone using the volume up and power button whilst plugging into USB but still nothing, I have also tried turning the phone on by simply pressing the power button but all I get is a red LED that blinks.

I have now come to connect the phone again to USB so I can monitor what happens and every so often the red LED light comes on (static, not blinking) for a few seconds then goes back off again.

I have read the first post of this thread but still somewhat confused as what I am to do to get back my working phone.

The phone originally had Android 4.1.2 and Build 9.1.A.0.489 then flashed with v2 of DooMKernel

Can someone please help

Thanks :)

Is your bootloader unlocked? It shouldn't matter, however it opens your phone to more possible damage :(

Did you flash a stock kernel?

Something may have kept the kernel from flashing correctly.

Look for changes in the phone more frequently. You may see it try to boot.

I think you need to try and flash again.

You might want to try the rubber band trick, talked about a few pages back. It holds the button for flash mode, and you leave it plugged in to a PC with flashtool waiting for phone in flash mode.

If the phone tries to start it should go in to flash mode because of rubber band.

A member had it fix his phone while sleeping.

Re: {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick

It is possible that after the crash the phone has not reset. A battery disconnect may be needed to reset. You could open the phone and disconnect battery ribbon, beware this will probably effect your warranty.

Or you can leave it unplugged for long time to let the battery die.

With a bad kernel recovery can be tricky. And as warned when you unlocked your bootloader, flashing custom software can severely damage your phone :(

I have just tried unplugging the phone from USB on the PC and holding the volume down and up buttons at the same time whilst plugging back in, PC detected the phone as a USB device if this is helpful to my issue?
[Sony Cross-Device General] Toledo_JAB:
Re: {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick

What happens if you just press volume down and plug in?

Maybe reinstall the drivers from flashtool?

I think somewhere in this thread there posts on how to recover using adb and fastboot.

From Jaramie's LT28at
[Sony Cross-Device General] karlywarly:
I can't get the phone to do anything again now and has gone back to a red led again.

Edit: Managed to get the phone to detect again from the PC but only for a couple of seconds then the red LED comes back on again

Edit 2: Managing to get the PC to detect the phone (can hear the USB sound) when pressing the volume down button and plugging USB back in but only for a couple of seconds, Could the phone need charging for this to last longer perhaps, maybe i'm doing something wrong?

Edit 3: PC seems to detect the phone somewhat when holding the volume up button and power button while plugging USB back in but only for a second, then red led comes on.
[Sony Cross-Device General] tavishx3:
I did flash the kernel with stock firmware downloaded from the list of them provided.

Just woke up again to nothing, while trying the rubber band trick but will be going to get a new phone today seeing as it was my only one and have felt disconnected to the world after 3 days lol.

Will still be trying to fix the phone so i'll keep everyone updated if I happen to fix it.

EDIT: Just went into flash and was aborted due to;

"Could not access phone after having opened it"

"Trying anyway"

"Error in processHead: 6: Handle invalid"

Re: {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick

Did the battery die during flash? Like green led went out.

If you have unlocked the bootloader (I couldn't find you say if you did or not) I was thinking this.

I have NOT done or suggested this before but....

You could try flashing bootloader relock file.

I may clean up any bad stuff from a custom kernel gone bad. And you can always unlock again.

Just thinking out loud. I have never thought about before.

If you keep getting the error that is.

From Jaramie's LT28at
[Sony Cross-Device General] tavishx3:
Battery didn't die during flash, and I didn't have an unlocked bootloader.

But, after work tonight, decided to go buy some tools and opened this baby up.

I unplugged the battery and plugged it back in after 5 minutes or so and got the red LED again.

Then plugged it in to charge for about 15min and tapped the power button and got a green led flash.

Got flashtool ready and full flashed my baby. Completed 100% and still stuck on bootloop at Sony screen.

Sooooo pretty much back to where I began sadly :(

EDIT: Did a hard reset after continuous boot looping to Sony screen and just unplugged the device again and just charged it to green LED.
[Sony Cross-Device General] stifilz:
Has anyone came across a situation where the phone could not charge the battery at all??

I left it to charge plugged in no LED or anything for a while and nothing happened. I ended up getting using a battery charger (for an i9000 Galaxy, and taping the wires to the bat) and ended up getting a proper one for the LT26i Xperia S, good investment $2 off EBAY. Ended up charging then booting sweet as. Not sure if I was being to impatient or there was something wrong with my phone.

Anyway, any thoughts?
[Sony Cross-Device General] AnrgKrshn:
Thanks a ton :D

My girlfriend's phone randomly soft bricked yesterday, plan on doing this tomorrow at her place, hopefully, it works! :D

Should I try to flash a new firmware without draining the battery? It's looping at the SONY logo, so I guess it's a kernel issue. Should I try flashing just the kernel? And if I am forced to flash the ROM once again, should I wipe data? Thanks so much, the first and second posts are so helpful, as is :D

Oh, her bootloader is locked, and it isn't rooted or tampered with at all, btw. I just want to fix it at home, because I live in India and the tech reps here usually just follow protocol, and she might end up losing all her data for nothing... So, help, please?
[Sony Cross-Device General] alwaysadeel:
try to get in flashmode and go for kernel first if device does not keep in flashmode because it takes less time, otherwise back to stock.
[Sony Cross-Device General] technaturology:
i've done until stage 6 and it's on, until i open some application/unlock lockscreen, it bootloop again...

so is that mean my ROM is broken ?? or my battery is really dead ??

because i've tried many ROM from stock ROM, and some custom ROM.....

plz help.....
[Sony Cross-Device General] Toledo_JAB:
If you flash just the kernel then you may be able to save the current system with the data intact. Just make sure nothing is selected in the wipe box of flashtools.

If you need to flash the entire ROM then it will be a factory reset. but sd cards will be safe.

I would try to flash the kernel first, to save the current system. If you get flashtool errors then try entire stock rom.

From the bootloops...

You can hold volume down and leave plugged in to PC with flashtool ready to flash. It may go into flashmode in between loops. Flashtool may say various things but sometimes it works.

You can try to do a soft reset ,1 vibration, during loops. With flashtool waiting for phone in flash-mode, as soon as you feel the vibration, hold the volume down and plug in to the PC. The timing of this can be tricky.

Lastly you can try a hard reset, with the phone unplugged. If the reset works then with the phone off, and flashtool ready, hold volume down and plug into PC. I dont normally recommend a hard reset but recently I have read about it working to shut off the phone. Just dont try to start the phone and make sure it is not plugged in when you do the reset. Try this as a last resort, before letting the battery go dead.

If you get flashtool errors then post a copy of the entire logs text.

If you cannot flash during loops the battery will die anyway
[Sony Cross-Device General] AnrgKrshn:
Hard reset turned off the phone, so I'll probably just flash the kernel tomorrow and see. If I check wipe data, sd card will still be intact, right?
[Sony Cross-Device General] Toledo_JAB:
Have you tried the basics? Like from recovery, wipe Dalvic & wipe Cache & wipe battery stats & fixing permissions?

Are you using a kernel that is overclocked? OCing the CPU to much can cause bootloops.

Does it happen with the phone plugged in also? If yes then most likely it is not the battery.

Flash back to a complete stock to see if it keeps giving the loops.

If a stock flash with the kernel included does not fix the issues then you can try re-locking the bootloader and test with complete stock firmware again. Relocking may clean up any bad files from a custom kernel gone bad.
[Sony Cross-Device General] Toledo_JAB:
YES

Sd cards should always be safe when using flashtool.
[Sony Cross-Device General] technaturology:
i've tried, wipr dalvik, battery stats, check overclooking (disabled), and using stock kernel and flashing and all of it doesn't fix the issue...

on charging, there is no bootloop, but if battery status = "charged" or if i open many application/ activate many services suddenly it turns off and on again...

this night i will try again with re-lock bootloader, i never tried it before...

Hi guys, I need some advice...

Last night (at 00:10 GMT +1), my Ion froze when I was using it. No respond, no soft-hard-reset. So I let the phone discharging all along the night and now I've screen off with red light.

When I try to plug it for use Flashtool or Seus, there is nothing. What can I do since I didn't saw my case in the OP (or maybe skipped, I will read again)

Thank you in advance.

Re: {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick

If you are able to get into recovery, TWRP or CWM, then your phone is working and is not brick.

I have no knowledge of TWRP. I would ask your question in the ROMs thread.

Md5 can mean bad download, or you changed the name of the file to flash.

If you want stock ROM back just flash your stock ftf file.

Reboot recovery, then quickly hold volume down to enter flashmode

Re: {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick

If, after unplugging the phone, the power button won't turn on the phone and power & volume up won't do any reset...

Then I believe you need to reset with battery.

Either unplug battery cable inside the phone or let the battery die.

Did the battery die during the update or did pc companion say update was a success?

From Jaramie's LT28at
[Sony Cross-Device General] wdnk:
I've reset the battery, i did it die for 2 days. And then when i plugged the battery to the phone, i charge it, it show blink RED LED, after 2 minutes, it shown GREEN LED (turn back to flashmode again :( )

When i hold power button during plug it to the charge cable or i do hard reset, it not responding, no vibrate, blackscreen, just.. GREEN LED.

If i hold vol.UP button during plug it to usb cable, it shown BLUE LED (i mean, i can enter fastboot mode), but still stuck why my phone cannot boot.

I've flash my phone with flashtool, it didn't works. I've flash it with Update Service and PC Companion, it still the same.

Help me, please.

i was flashing the 2 ghz kernel for paranoid android and i think i got low battery during flash

so something got wrong and i couldnt boot

i got a backup threw cwm

Xperia ion lt28h

I was on paranoid android before

[Sony Cross-Device General] Toledo_JAB:
Did your battery go dead yet?

I dont THINK unplugging the battery would hurt.

If you unplug then use the rubber band trick on volume down button and then plug in to pc with flashtool waiting for device to flash. It may take some time to charge if battery is to low

Please report back if you unplug and it works ;)
[Sony Cross-Device General] technaturology:
thanks Toledo, it was battery problem, i buy a new one and replace it, and it working again :D:cowboy:
[Sony Cross-Device General] CRHASH:
so by unpluging the battery cable and butting rubber band on volume down and charge for a time you can get into flashtool to flash ??

because now when i woke up the red led has stopped i had it plugged to the charger over the night

plugged into computer and the red led come up again and stopped after about 10 min

[Sony Cross-Device General] DeathEvil:
so I was running legit att xperia ion unrooted completely stock... Yesterday I thought, "why not restart?" because its been running for months as daily driver for my mom. I noticed there was no restart option, so I choose shutdown. Nightmare started. I was unable to turn the phone back on!

tried power with vol up and down and nothing, nada, no leds, no vibrations, and if that wasn't enough the phone kept getting freaking how to the touch. After a while it stopped getting hot but all symptoms remained, so I decided to plug it in for a few hours, after which I did get the red led to light up. At that point I tried sony software to repair the phone, but computer did not recognized the phone because it did not turn on (by pluggin usb and holding power and vol down). After a minute or two, I'm back in square one - no leds, vibrations, or any signs of life. I suspect after a while being hooked up to a charger, I will get the red led again, but at this point I'm not sure how to proceed.

I could try a flashboot, but isn't that the same as trying to repair with sony software (which did not worked)?

Re: {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick

As I described in the OP, there are 2 modes for flashing.

Flash-mode & Fastboot-mode

I think you just mixed them together with flashboot :)

Our AT&T Ions can only use Flash-mode. To access Flash-mode you start with the phone off & unplugged, hold only volume down and plug in to PC.

You said you pressed power also.

After it heating up and not turning back on I would check about warranty.

The heat thing would bother me enough to call Sony. Should be covered by 1 year warranty by Sony.
