Please read all of the first post above and then all the instructions FIRST, before trying anything. If you are unsure about anything PLEASE ASK QUESTIONS. No one wants you to damage your phone. So make sure you understand what your doing. If your not sure what your doing you could do more damage to the phone
And remember with an unlocked bootloader you can do severe damage.
ATTENTION:
If your phone is not working but you see a led or have bootloops DO NOT USE HARD-RESET. This can make your phone lock/freeze up until the battery dies. It took 51 hours for mine to die.
However if you get stuck on a boot screen or get bootloops a SOFT-RESET may work to reboot.
If you have unlocked your bootloader this guide may or may not work for you. If you have trouble recovering then see the "TRICKS that require FASTBOOT-mode" below.
YOU NEED TO RESET YOUR PHONE!
If your phone is soft-brick and does nothing when, -the buttons are pressed, -a charger is plugged in, -or if the screen is still ON then....
- The memory chips need lose power to clear the bad data and reset the phone. Either by the battery going dead or by unplugging the battery.
- You can to leave the phone on a charger to see when the battery dies. Usually the battery will not charge in a soft-brick state and will die while still plugged in. After the reset you should then get the red led. However if you get a red led immediately when first plugged in and no response but red led for a long time, then you may need to leave the phone unplugged and let the battery die.
- Only after the chips reset will you get the red led. The RED LED should mean the phone is charging in 'low battery level charge mode'.
- Once you get the red led, after the reset, do NOT try to turn on the phone. If you try to start the phone now without fixing the problem you will have to start all over.
UNPLUGGING THE BATTERY
If you feel like taking your phone apart you can unplug the battery. Most 2012 XPERIA's have a built in battery that is not designed to be easily removed. However next to the battery there should be a ribbon cable with a plug to the mother board. Unplugging this cable for 2-3 minutes should reset your phone without letting the battery die.

CAUTION: this may effect your warranty

The Rubber Band Trick
Here are some links to help describe the rubber band trick.
Now after the phone has reset and you have the red led.
~ Make flashtool ready to flash your stock.ftf file. If you are experiencing errors while flashing the entire ROM try to flash just the kernel, check off all in the exclude box except kernel. At this point your battery is very low and doing this will make the flash process much faster than trying to flash the entire ROM.
~ Try to connect phone in flash-mode. If your phone has enough battery you will get green led. If the flash fails on the first try, just put it back on the charger and wait about 10-30 minutes and repeat. It may take a while to charge enough to flash.
~ If you see the red led go out, then try for flash-mode.
~ If you get bootloops, try to flash between loops. As soon as you notice loop, hold volume down and plug the phone into PC with FlashTool ready. Once the loop starts you have very little time to flash, before the loops drain the battery. If you can not flash, the battery will have to die and phone reset. Then start over with red led.
~ After you complete the flash, unplug the phone and see what happens. Sometimes it will boot to Sony screen and then shut off by itself, if so plug in to a charger. You should get the red led then the battery charging screen then. After about 20 minutes of red led.
~ If you get a green led (for flash mode) then press the power button until 1 vibration. The green led should flash 1 time. This will end flashmode and start the phone. If you don't end flashmode the phone will still give a green led whenever plugged in, but it will not charge, until the battery dies and the phone resets again.
~ If you were able to flash the entire stock.ftf file and your phone has gone from red led to the charging screen, then your phone should now be recovered and turn on normally.
~ If you could only flash the kernel then you will get bootloops. Again you can unplug and try a hard-reset to turn off the phone. If hard-reset works plug in charger and wait for red led and then charging screen.
~ If you don't do a hard-reset, the phone boot looping should kill the battery and then plug in charger (this is what I did). Then wait for red led and then charging screen.
~ Now you should have a good kernel and the phone plugged in. You should have the charging screen with the battery icon and led for 'off-line charge mode'. Charge until over 50%. A quick press of the power button will bring up the charging screen.
~ Once over 50% then flash the full stock.ftf with a full wipe.
~ If you got this far but still cannot flash a full stock.ftf file then try to use PC Companion software to REPAIR your phone. Make sure battery is more than 50%.
~ If all fails then post a copy of the FlashTool log in this thread.

List of those that have recovered
thank you! Worked perfect!! as hard as it was to let the battery die I did it and she worked!!!![]()
My phone is working again, you just have to be patient, as it took >16 hrs for my phone to turn on. Once my phone turn on automatically, I had let sit for 4hrs, then pressed the power and volume up buttons at the same time and held it for exactly 5 seconds, it then turned off and I was able to flash as normal. Just be patient. Thanks everybody.
Here are the steps I took successfully revise my phone from soft brick.
[*]That is all ... Back and running.

GOOD Luck.
Timing = could be different from phone to phone - depends on battery of the phone before it dead.

Did Hard Reset and phewwww Phone is Completely Dead Unresponsive.
BUT DON'T GIVE UP....
Many Thanks To People Who Have Shared Their Experiences Here.. Keep It Up Guyz.:good:
In last Thursday I decide to get back my bricked ION and then follow the instruction as markelON suggested.
And when I tried 2 hours later, I've finally get the Xperia logo again, and everything become working!
In my case I found later that the speaker in back of the phone has broken. I don't sure this was already broken since the phone bricked or between the repair service tries for recover my phone. But other functions are working and my dad had car accident recently. So I keep my phone and still not send back to repair service yet.
Now it has hardware issue, not brick, so I could call the repair service to fix it now. :silly:
I thank everyone who lend the help, especially markeION.
Thank you very much.
P.S. I has also written the fix instruction summary in my language and publish to local community too, based on markeION suggustion. So I think this would help others who aren't skill the English language too.
Thanks!
I was able to get it in fastboot mode, i will now try to fla****
this is what i did for the people having the same issue.
once you get the boot loop press power+vol up until you get first vibration, after that very quickly you need to plug usb to the pc while holding only the vol up key.
this worked in a xperia ion bootloader unlocked
Thanks everyone for your help. i got more experience now, i hope this helps to everyone else that have or get the same issue.
Remember when you get bootloop press power+vol up until you get first vibration, then very quickly connect the phone pressing vol up or vol down to get fastboot or flashmode, then you can fix the phone with flashtool. this worked for my Xperia Ion bootloader unlocked
Look, right now i am in Fastboot Mode! This time it worked again. But when i try to flash a kernel.sin it says that there is no device! What to do man??
EDIT: WAIT, NOW I AM IN FLASH MODE AND TRYING TO FLASH KERNEL! But after a few seconds i get this:
EDIT 3: I made it! I had to flash the whole Rom. Not just the system.sin and kernel.sin. THANKS FOR ALL YOUR HELP!
So I don't do anything about the purple led and just redo the steps?
Okay o_o
-edit-
whathe
I GOT IT TO FLASHMODE
After charging and having constant red led to no led (?) I unplugged from the wall charger and and then plugged to laptop to wait for bootloop. So there was red led, then after a while no led again. I just pressed down (didn't expect anything to happen lol) and then I got GREEN LED!!!! Luckily, I already set up flash tool
I installed ALL the drivers in flash tool
But there was no Ion,
right now i'm installing pc suite cause my sister said there are drivers there.
Am I doing the right move? O_O
-edit2-
MY SISTER WAS RIGHT
IT FLASHED ALL THE WAY THROUGH!!!
btw, checked Exclude TA, is that correct?
phone still won't boot (assuming no battery)
I'M CHARGING RIGHT NOW!!

THANKS TO THIS THREAD , AND ALL CREDIT TO ALL XDA Developer Who already tested all trick and method and provide all TOOLS :highfive:
IM NOT GOOD ENOUGH IN ENGLISH . PERIOD
Thanks for the answer and the miracle has happened, my phone is back from the dead. This is how i did it:
I got frustrated with the phone after it wouldn't respond to the soft reset it was trying (power + volume up). Then i pressed the volume up button while playing a game with the other while in the corner of my eye i see the light changing color and yes, it had gone into fastboot. After that i flashed the kernel only, but the phone wouldn't boot. I was angry that i let this good chance slip, but i managed to do the trick again: just keep pressing volume up, until it went into fastboot. I flashed the stock rom and my phone worked again.
Moral of the story (and something to put in the startpost): Even if the screen doesn't show anything and even if the phone doesn't vibrate or give a signal to indicate the battery is full it can still go into fastboot if you press the button repeatedly and keep trying.
Thanks for the help!
Worked like a charm for me brother. Installed something to my L28at and it was showing incorrect battery and couldnt re install original OS. Now I am good!
Anyone can help me please, i have strong red light and i can't flash again.
EDIT: Now, after unplugged and waiting 5 mn, i plugged again I see the logo of the battery:laugh: and it appears that it is empty after 20 hours of charging lol. I wait a bit and I'll let you know if I can flash:fingers-crossed:
EDIT2: I installed cm9 and restored my backup. everything is ok now.
Mine is the same problem, the kernel does not support offline charging, and the issue is that: the phone runs out of battery - It gets booted up after 5 minutes charging and then turn off. The cycle continues.
I solve the problem by:
- Let it charge till the screen boots up.
- Power + volume up for 1 vibration, and then hold volume up for fastboot mode.
- Flash adv kernel 17 and then connect to charger. Let it charge for 30 mins.
- Reflash the Rom kernel.
Everything works perfectly after that.
Thanks it worked!
But is there a way that you can use the phone with pc companion after flashing it?
Because pc companion told me i have a wrong firmware...![]()
Alhamdulillah ~ SUCCESS :good:
SUPER Thanks To Everyone Here~!!
:victory:
ok i after about 9 hours of charging i didn't get any response from my Phone (ion)
so i decided to open my phone and disconnect the battery cable !
after i disconnect my battery cable and plug it again i connect my phone to wall charger and get a red light LED.. after about 20 minutes red led become orange then i connect my phone to pc and start flashtool and flashed new TFT file
all i am saying is that if u don't get red light after couple of hour you have 2 options !
let the battery drain then start charging or unplug battery cable then plug it back
here is the picture of my ion's battery flat
Well I recovered my Ion.
Now for some reason I cannot flash any baseband when using win xp. I can flash basebands from ubuntu though. It took me a few hours to figure this out. Tried reboot, older version and every stock ftf I have, ics & gb. I can flash all other parts of the stock ftf. Baseband freezes flashtool up at processing the data and I have to close flashtool.
Not sure why win xp wont work, but since linux worked I dont care
I got some good tips to add to OP.
Flashing just the kernel requires less battery charge to flash and fixes offline charging.
Also unplugging the battery after back pieces are removed should eliminate the waiting for battery to die, if you can handle taking phone apart. Battery unplug should save a lot of time in both discharge and charging. If battery is full if will take days to discharge. But if you unplug it should reset and keep the charge for flashing.
Well now on to my wifes captivate glide. It keeps shutting down when data is turned on. Time to learn about odin and Samsung![]()
