You can follow 2 methods.
Easy but time consuming method:
Connect your phone to charger and wait untill it automatically reboot. The flash ftf file. (It may take 10-15 hours or more to reboot)
Difficult but fast method.
Dessemble your phone. Remove/disconnect battery cable from your phone. Reconnect it. Connect it to flashtool as fast as you can and flash ftf file.

You need to look for the bricked thread in general. You have two options
1. Take it apart and undo the ribbon cable.
2. Go through the steps in the bricked thread but it will take a long time and you have to plug it into the factory charge block not your computer.

I have such a problem too. I rooted my XPERIA Ion phone successfully and restarted. the phone was healthy and had no problem. I installed font installer and selected a font and installed it, rebooted and my phone went through bootloop and continiously restarted. XPERIA logo appeared and after several seconds disappeared for about 30-40 minutes untill it turned off and now no charge no boot and no shutdown. I tried to flash my phone by flashhtool but Windows coud not recognize my phone. Just display screen is on and no image no OS no menu is displayed and you can't access anything. please help me.
thank you

Switch off your phone and charged your phone until orange led glow.maximum charging time 15hrs to 35hrs.then you will see that orange led come up.after orange led come up charge your phone until green led.then plug out your phone and flash your phone with flash tool.

As avik said you need to let it charge. You are in a soft brick state so you will need to put it on the factory charger and let it charge until you get a response from it. If you mess with it before it is ready you will only make it a longer process.
I would not try changing the font unless you are on a de odex rom. If you try to change things on a factory rom you will most likely get a boot loop.
After doing a bit of reading on the app why in the world would you even try it?? So many reviews saying it bricked the device and yet you still tried it?? Make sure you read thoroughly before you go trying out stuff. Every response for a newer device is claiming a brick so use your head.
Even i have the same problem which was said by user:avik6123 . what does reboot technically refer to is it just seeing red led light over the mobile or will it switch on automatically. i have got the red led but when i connect it to system with usb cable holding volume down key it doesnt show the green led (flash mode). only the red led is on as if it is charging. can u please help me out??
Just find the soft brick thread at the top of this forum...it'll solve nearly any software related problem you're having...its just a matter of being patient and letting the phone battery completely die...
The main soft brick most owners run in to is trying to hard reset the phone when the device is in a state that you shouldn't do that...holding volume down for 10 seconds with the power button for 3 vibrates is a sure way to completely trash the kernel if the phone is in some sort of problematic state...
you then need to make sure the phone is not responding to anything...no button presses or combinations give any sort of response...then put the phone on the WALL charger...if the battery has not died yet, you'll get no LED when plugged in...don't worry about it being plugged in, this is NOT charging the phone yet...its just a good gauge for when the battery completely dies...after 10+ hours, the LED should start to blink red...leave it on there...after another couple of hours, it should turn solid red...now you're getting somewhere...
you can either get flashtool ready and try to start flashing back to a 'safe' firmware and/or just the kernel...or leave it on the charger until its solid green...which will remove any threat of the device having enough battery to complete the charge...If you take the phone off when LED is solid red, but still not getting into flashmode properly...its need to charge a little longer, and always use the wall charger for this...it charges much faster...
NEVER try to start the phone in this state, though...you'll end up right back where you started...the brick is happening because of corrupted boot data, which will be on the device until you flash over it...the hoops you have to jump through to fix it is all because of having a sealed battery...thats why it takes so long and is so annoying, but what is causing the problem is actually very simple to fix...you just have to be patient and read all the tutorials in order to get out of it...
You don't need to put your phone to charge for like several hours, that's bull, just flash another ROM. I've done it so it works even with 0 % battery power. So anyone who want's to comment my advice, get lost.

What do you mean by flash another ROM. I don't know much when it comes to this stuff but my phone shut down and i could never recover. When I plug it into the wall charger, the red light comes on but I don't know what to do from here. Could you help PLEASE!
I would recommend attacking a rubber band around the volume down button while connected to the computer where flash tool is already in the flashing mode. This way, it will immediately flash as soon as it can.

I can not download a flash tool program to my computer so how will it go into flashing mode. Sorry i'm not very good with this kind of stuff. I know it's frustrating. If you could give me detailed instructions, that would be greatly appreciated.
Ok, so i finally downloaded flashtool but my computer doesn't detect my phone when I plug it in. When I search for devices, my xperia ion is not in the list. Please HELP!!!!
@Shortie71
In order to even contemplate flashing, you NEED i repeat NEED flashtool.
http://www.flashtool.net/download.php
You MUST download it to flash anything onto your phone
The issue you are having is a drivers issue.
My recommendation is to ask in the MAIN question and answers thread about where and how to get drivers since your phone is already soft bricked (installing sony pc companion and inserting phone will therefore not work)
Then, you can properly flash after you have the proper drivers

Hi all,
Need some help with my Zenfone 2 ZE551ML 4GB/32GB.
Decided to flash Nougat custom ROMs so followed these steps
Connected phone to PC and ran MM BL upgrade. It completed successfully.
Rebooted to BL, then rebooted to recovery, saw the new 3.0.2-M1 TWRP.
Went to TWRP and activated Sideload, ran ADB sideload command to load Nougat DU. It completed 100%.
Proceded to sideload gapps but connection failed. Maybe need to reactivate sideload in TWRP again.
Touched USB cable and the phone switched off. Ever since then it does not boot up and screen does not light up anymore.
Phone was on MM RR, BL unlocked. Battery was at 100% when performing the above actions.
Is there anything else (other than bringing it to ASUS) I can do to revive the phone?
Hi , I'm in a rush here , just one question to start ..
Can you get into bootloader via buttons not connected to charger ?
Do you know how to ?
Ps , you don't need to sideload roms in twrp , you just install them after usual wipes.

I can't. The way is to press the volume up and power buttons at the same time, and release the power button when the phone vibrates after a few seconds.
On my phone there was no response whatsoever.
Yeah I know I don't have to sideload ROMs, but I was lazy to copy it to the SD card.
Plus I had plans to wipe the internal SD card, so didn't copy there either...

Sounds like you are bricked my friend
but do try holding power button and vol for a good length of time...then power button too on its own for some time..
If and when you get two vibes , if no boot loader
Check unbrick threads .
If get bootloader , scroll to recovery select it .
Next time download roms to fone
safer !
I think kernel is in panic mode. Try disconnecting the battery for a little while and then reconnect it. You'll have to open your phone to do it. There are many YouTube videos to see how you can do so. It's not that difficult. Good luck!
I'm in the same boat... no even LED while connected to the charger... Already disconnected the battery and closed again. No joy. Is this a "deep brick of death"?? Its too expensive to give away without fight a little. Any help is more than welcome
There are threads on xda that describe how to revive hard bricks.
For me, disconnecting and reconnecting the battery had worked.
Please make sure that battery is connected perfectly.
Sometimes , leaving on charge brings at least the two vibes back eventually
That's enough to start xFSTK unbricking process.
Besides the already mentioned battery disconnect.
I seen one guy revive by disconnecting USB board too

Looking at unbricking threads.
Problem is the PC was unable to detect the phone in IntelSOC mode. Absolutely no response.
I will try different OS and machines though

You mean leave it connected to PC to charge until the two vibes came back?
I originally did have the two vibes, but the phone was connected to the charger at that point.
Unfortunately I don't have the vibes even connecting to the same charger now.
I believe the solution now is to try to recover the bootloader and restore the OS.
Question is how to get it detected in PC in IntelSOC mode.
Things to try:
Disconnect battery
Disconnect USB board
Try different PCs and OS

When you get two vibes back , you can install isoc driver and your PC will recognise it.
In the early days before unbricking knowledge of zen 2 , I also witnessed the same , blank screen no vibes
What I did was leave it on charge , every hour or so ..press power plus vol plus , quick press , then after a longer press , if nothing then just power , quick press and a longer press.
Then I awoke to the vibes
Once the vibes start , then its install isoc , don't install xFSTK downloader until driver is set up
PS , that was before we found discon of battery method and still had warranty

Can I ask how many times you tried before getting the two vibes back?
And it was connected to the PC's USB port?
I asked because I did have the vibes when connecting to the wall charger.
But it went away when I then connect to the PC. And now there are no vibes even when connecting to wall charger.

Leave on charge , means exactly that, leave on charger .
Leave it on a full day , if fone gets warm its charging .
Try all the stuff already mentioned.
Some people have give up , thrown fones in draw and 3 months later come back to life.
Some people hot wired battery straight to charger too, but that's off limits .
There is nothing straight forward that works for everyone , here is a few exanples of what revived many fones ,you pay the price for being lazy
We all learn the hard way
Urgent Help needed
yesterday my phone battery was 20 percent so i tried to charge the phone but it is not charging and showing charging symbol i did't notice till 5 percent while i was searching in the internet about the problem it went to 0 percent now my phone not charging with charger and computer
when i am connecting to computer usb not recognized pop up in all ports
what can i do now?
I am in Resurrection Remix oreo
The problem is with your USB cable. Try using another cable (not cheap ones).
I tried with other cables and no luck any suggestions
are you sure that is cable problem ?
because once it went to recovery and i did wipe out everything i thought the problem with the rom but same problem

Touch also your charger, it should become warm. If it's cold than it's dead probably. Try another charger.
Change to AEX Oreo, latest.
the same thing happened to me when I busted my original type c cable. tried with the cheap ones, got damaged. but tried with a friend's mivi cable and worked perfectly.
Hello XDA universe, I need some help to fix my Dead Samsung Galaxy Note 2 (N7100).
In Elaboration, My N7100 was working fine 7 days ago, and I was using CM12.1 on it for over a year, I decided to install CM13 on it, I did the same, first boot was successful, phone booted up like always, then I plugged the charger in and performed a restart, but I didn't boot after that,
Now, I'm left with No display, No Recovery, No Download Mode and No Hope.
I tried using the USB JIG method to get into the download mode, but failed, maybe I didn't do it right,
Please help me out, It was my Mom's personal phone, and I have heard a million scoldings for doing this....
Please somebody help me....?
Do you see the charging screen or charging LED when connected to a charger?

Sir, thanks for replying, It did that on the very first incident, now it's good as dead.
Please tell me how to recover it.
When the phone is connected to a charger, does the phone get warm? If yes, it could be charging.
To use the jig, remove the battery, insert the jig, insert the battery. The phone should automatically vibrate and boot into download mode. About 15 seconds after inserting the battery, remove the jig, connect the phone to a computer, and see if it shows up under devices.

Accidentally my phone droped on the floor after that it kepps the mi logo loop after some time the battery got dead and phone also not charging. While connecting to the charger cable the led blinking and looping. Buy my phone doesn't charging and while on the flash process without battery the fastboot mode opens and closes rythmically.and my computer doesn't take the time to load the drivers. Now what to do feeling dizzy....
Please help me out of this problem. I think it bricked but not hard. Because the fastboot logo comes but not more than 5 seconds it goes off. Please help
Try giving it to a local repair store.
I also had the same problem. If I used to remove and put the battery back, it used to reboot. I tried flashing using fastboot, but it used to reboot every 6 seconds. According to some friends of mine (Thanks to them) I gave it to a store, which in turn (I dunno how) hardbricked the device. I connected it to the PC, tried to go to fastboot, and it shows up as QCOM Loader 9008, which basically tells you your device is hardbricked.
Fastboot didn't work.
Using MiFlash Tool, while flashing through the QcomLoader, it showed "Did not receive hello packet"
Tried many times more, didn't work out.
So, I went and tried the trusted method: TEST POINT method.
It worked out. Now my armani is up and running!
TL : DR;
Try giving it to a local repair store (not Mi service center, they didn't help me AT ALL.)
Something might have dislodged.
Or
Try testpoint method, google for it
it *might* work. Well, that worked for me.
Not end at all
Hi, sorry for very late reply
Recently I discovered that the battery is dead not working at all. And while doing the test point method I think battery power is needed! So I ordered a spare battery after the delivery I will do the test point method agian. Currently if I plug in my phone thorough usb to my computer the qcom 9008 port shows but while flashing it gets detached then re shows up . And the flashtool error happens. I think a battery power is required so that this failure is happening.
So, what do you think is edl mode requires battery power?.
Need help because I have to fix it. It's my one and only loved phone of all time.
Currently I am using my friends phone to discuss about this matter.....please help me.....

You do not need battery power for test point method.
