You can try the rubber band trick as it may work as it is looping. I have never used that method.

Close flash tool to try my method below. This way makes sure everything is good to go.

What I did was shut the device off by holding Power and Volume up just long enough for the screen to go off and let go. It should be about four seconds or so but it is before the first buzz.

When you get it to turn off unplug it and make sure it connects in flash mode. It may still need to install a driver so this is a good way to check.

If all is good open flash tool and see if the device is recognized and set your flash. Should run with out issue and you will back up and running.
[Sony Cross-Device General] Droiiiiiiiiid:
I did the Power and vol up to first buzz, now I have a blank screen Ion (still lit however) and the computer recognizes it as SEMC Flash device. But no LEDs now. I have it sitting plugged into the computer rubberbanded. Is this right?
[Sony Cross-Device General] zackspeed:
Yea you just put it in softbrick again. That is why I said let go before the first buzz. Put it back on the charger.

Here try it this way. Leave the rubber band holding the volume down and let it charge on the computer like you did and maybe when it comes back it will go into flash mode.
[Sony Cross-Device General] Droiiiiiiiiid:
Does that mean it needs to be disassembled again? I have a red light charging now and it went directly from the lit screen to that
[Sony Cross-Device General] zackspeed:
Just leave it and let it charge and follow the instructions. With a bit of patience and understanding you will get your device running again.

Hi all,

If I'm posting here, you doubt I'm in pain...The victim is my brand new Xperia Z.

Symptoms: no button reaction, no led, no...nothing!

The weird thing is that when I connect it to Flashtool, it recognizes it like being in Flashmode (without pressing any vol. button!) but can't flash anything (FlashHeader error 2 or 22)

I read the OP a lot of times but I have a doubt, now.

It's been charging for almost 15 hours now, I saw once the fix red led which lit off a few minutes later...

My phone is constantly on wall charger. Should I wait a long time more? Is my phone definitively dead?

Thanks

Edit: I just saw the red light for 5 minutes...then it lit off once again... :(
[Sony Cross-Device General] Captain Droid:
Specfic spot is this, when it asks you to connect your phone with the specific button pressed.

You can do the wall charge and wait for the green or red led to appear.

If u cant see the Sony logo, then your kernel is damaged. You charge the phone till you get the red led. then try to flash the kernel , just kernel from a stock ftf.

Or the

easy way is to remove the battery cable and reconnect it. that saves hours of time, trust me.

report back if you get something to work.

im so happyyyy
[Sony Cross-Device General] frycookman:
Hi, thanks for your reply! I finally got it to work and have successfully recovered my Ion and even flashed to JB! This thread helped me save buying a new phone! :) gladly appreciated and OP thread starter has been thanked as well as you sir :)
[Sony Cross-Device General] Captain Droid:
Dont try to turn on, it wont work.

Just keep it charging for sometime. say for 5-6 hours wall charge.

If u r getting a constant solid red led, (thats low power charging). u will have enough power to flash a kernel alone.

make ur flashtool ready connect the phone holding the vol - button (in acro the button will be different ) and keep holding it for sometime ( minutes) u wil be getting a solid led.

keep on holding for someminutes , the flash tool will start flashing the kernel.if u were unable to finish the flash , keep the phone charging for some more hours. read the second post in OP to understand more about the battery cycle.

you can recover your phone.

[Sony Cross-Device General] v0ids0ul:
Yeah, the mod I flashed was from the pimpmyrom app in the play store, so like an idiot I assumed compatibilty.

unable to get the flash mode green light after 3 beep reset

Hello,

I am from India. have an Xperia Ion LT28i.

I flashed the latest 6.1.E.2.29 after which i was unable to root or even install CWM.

hence I followed the boot unsecure rom with the .111 elf file and flashed it from the fastboot mode and restarted the fone.

after restarting, it started looping at the boot screen and never stopped....

I did a hard reset by pressing Vol- + pwr btn until 3 shakes.

after that my cell phone is not able to start.

i let the battery go dead after which the red led comes up when i attach the charger.

after about 10 mins, the sony logo comes up and it boot loops for 5-6 times and then stops.

the screen backlight remains on till the battery drains, but does nothing.

i tried holding the vol - button and attached it to the PC when it is boot looping, but no use as my PC does not install the drivers.... (it identifies the Phone though), but the green light does not come up on the phone....

I also tried to connect the wall charger while holding down the vol - button, but still the green light doesnt come up.

what do i do???

My cell phone is out of warranty too.

am worried.
[Sony Cross-Device General] accts:
Have you try to redownload the firmware. Also update your flashtool (if haven't done so)

---------- Post added at 08:08 AM ---------- Previous post was at 08:04 AM ----------

Let the phone die and charge for a long time until you get green light (or more than 50%). Reflash firmware, follow the new easy root method.
[Sony Cross-Device General] Toledo_JAB:
have you tried checking 'exclude TA' in the exclude box when flashing the I versions?
[Sony Cross-Device General] FanDroid09:
No i haven't, ill give it a shot for sure though... ill report back after, if i can manage to get it into flashmode again! It is an extreme hassle for some reason haha i have some sort of super soft brick that no one else seems to have.
[Sony Cross-Device General] Toledo_JAB:
Have another look at the OP, it has been updated. I hope it helps

[Sony Cross-Device General] vnayrp:
Thanks Buddy...

Hey Thanks...

I tried a lot, but was unable to do anything....

I gave it to the service center and they too could not do anything.

Luckily, i came to know that the service center people had sent a request to sony india for a motherboard swap... :good:

I am so relieved getting to know that the swap has been approved and the motherboard has been dispatched to the service center ;)

hopefully, in the next few days, i will have a complete new device with a new IMEI with a locked bootloader (i suppose)

thanks anyways, CHAO!

[Sony Cross-Device General] FanDroid09:
I tried flashing and excluding TA... the process made it further along... but it still aborted at 93%

haha i was very excited there for a minute. Ill try again but i dont see why it will work this time, any other suggestions?

thanks in advance i really appreciate it!
[Sony Cross-Device General] accts:
Unbelievable - SOFT brick again :crying: ... trying to deodex the new fw 6.1.E.2.68. Now my device is unresponsive neither to soft or hard reset. Waiting for the phone battery to die and see if I can do anything after that :rolleyes:

Edit: whewww...So glad just had to wait for battery die - recharge ! was able to reflash - back in business again :victory:
[Sony Cross-Device General] georgeting91:
I've just encountered the same problem as you did. After charging until the red LED is solid at a certain stage I disconnected the charger and tried to enter flashmode but to no avail. When I connected back to the charger (red LED on) after awhile the Sony logo pops up and slowly fades away (becomes yellowish as you mentioned earlier) and again and again. So does this mean the only way is to try to flash it in between the bootloops? Sounds kinda hard as I already failed multiple times and ended up hard resetting it and charging it again. :(
[Sony Cross-Device General] Toledo_JAB:
Try leaving it plugged in after you get red led. Red led is not enough battery for flash.

If still boot loops then try doing a soft reset when Sony first shows.

[Sony Cross-Device General] georgeting91:
I just came home and I left it unplugged since yesterday morning. Now there's completely no LED. I unplugged and plugged it in and the LED is red again. It went to bootloop so I tried to enter flashmode between the 1 second bootloop gap but failed a couple of times and now there's no bootloop but the screen is still on. OMG this is torture. Lol
[Sony Cross-Device General] ganeshbiyer:
Have patience, it is the key.

I am in the same situation for the past day and a half and still only red light for me. :fingers-crossed:

So don't rush, you will be able to flash firmware eventually.:) It will go to flash mode, you will have some boot loops in between. Don't do anything just yet.
[Sony Cross-Device General] faiisfaizal:
hey my red led just turn of when more than 16 hour charging as i see. then i unplug it from the charger...thhen connect it to pc to enter flashmode as they said but when i connect to the pc still red led appear....but no flashmode........so i reconnect back to my charger and still red led now

What ROM?
[Sony Cross-Device General] gave012:
i just simply let my ion rest for a while.. for me before i soft bricked my ion it was in 39% of charge and it die for exactly 4 hours. why i know? i plugged it with the wall charger and the red light begin to turn on and off. and this is what i did. when i noticed that the red led does not blink off i waited for it to charge for 1 hour in the wall charger. then after wards charged it with my computer with flash tool ready. it just take me 5 mins so the computer can recognize it. let it be recognize as the xperia ion in the pc companion and when it is recognized by the pc companion i quickly unplug my phone in the pc and pressed the volume -(down) and plug the usb on my computer again then boom!!! it flashed.. in my cased i only need the kernel thats why its really fast to flash then my phone is back and now enjoying the rooted jb from sir spectres pre rooted stock rom.

by the way i advice that let the pc companion on before you flash. in my own thinking it helps the phone to be easilly recognize by the computer and the flash tool. just a fact and no basis about this. thanks i hope this will help you.. and this is based on my own experience.

for the total time i assumed it to take 5 hours and 35 mins before it has been unbricked.

kudos and good luck..

Xperia Z

after 3 weeks of long suffering.. I guess it's time to say goodbye to my xperia z..

still no bootloop nor a green or blue led..

just a red led that lasts for about 10mins then off

no vibrate on power + volume up

flashtool still sees it with MTP debugging off mode

pc companion and seus wont detect it

rubberband trick not successful

left it connected to wall charger for 5 days straight

left it unplugged and untouched or 5 days still nothing

thanks for all the support :)

switching to another unit for now :)
[Sony Cross-Device General] dd66:
well I guess my Z is totally dead, now :crying:

When I plug it with Flashtool opened (without touching any button!), it says I'm connected in flashmode then disconnected, then flashmode, then disconnected and so on...When I try to flash any kernel (the shortest thing I think) while in this theorical flashmode, I have an flashheader error 2 or 22, or something like "unable to read device after opened it" thing...

I'm going on holidays, now, will let it die peacefully and see if I can do something when I'm back in 2 weeks (should I let it plugged on a wall charger during this time or not?)

Thanks for ur support (if u have any last idea, I'll take it ;) )
[Sony Cross-Device General] ChoirBoy1:
Hi guys, I need help with my Xperia Ion. *Note I have read the instructions on the first page*

I tried flashing Jelly Bean on my ion for the first time (got impatient waiting for official release in Canada) and used Flashtool 0.9.2 beta (did not realize, should have got the 0.9.1 stable one argh). I put my phone into flash mode as instructed, and was about to flash (got the green LED, flashtool says its in flash mode), and then it just switches back to being connected through USB (phone boots onto sony logo), which I thought was odd. Since I thought it wasn't actually flashing yet, I yanked the USB cable from the phone. I think I repeated the steps one more time and still the phone is in flash mode while I plug the cable in, but after a couple (10?) seconds, it switches off flash mode and just boots normally.

So at this point I give up flashing and just want to use my phone as normal but the screen is dark, I can't turn it on, and soft reset does not do anything. I tried plugging my phone into the wall charger as instructed and no red LED. Left it charging overnight for about 11 hours and still no response as of yet. I did try to turn it on/soft reset/unplugged and replugged USB cable a few times in that 11 hours (but I did have 8 hours consistently where I did not do anything at all besides keep it plugged in) but still no red LED.

When I plug it into flashtool it does say device connected with usb debugging off

I was being slightly impatient as I was hoping I could this fixed overnight to use my phone but i managed to switch back to an old phone so now I'm willing to be patient. I thought of removing the battery but didn't have the torx screwdriver needed to unscrew. At this point (no response whatsoever), is the best thing I could do is leave it plugged in the wall until I see a red light? Or should I leave it unplugged?
[Sony Cross-Device General] Lusto:
Xperia S cannot get behind red led

Hello,

I wrote here several days before, that I couldnt get into flashmode, cause Flashtool cannot recognize my device. Any suggestions?

I can get red led easily, after it should be kernel charged, it goes off, and the most interesting part is, its not looping, I have to manually unplug the phone and plug again to get the red led again. tried everything, even plugging into wall charger for like 2 days, with no effect,even the rubber band trick, but as i said Flashtoool cant recognize my Xperia S... once the red led goes off, phone remains black with no response. then i have to replug it again. any words of advice?

thanks for every reaction
[Sony Cross-Device General] tangosierra_:
Let the battery die first, leave it for some time unplugged.
[Sony Cross-Device General] blackcat510:
I'm holding my friend's Xperia S

He has unlocked his bootloader, then he use Sony PCC and it bricked :(

The phone status now is completely bricked, except when connect to wall charger, it has red led

When connect to the computer, flashtool said

13/044/2013 22:44:25 - INFO - Device connected with USB debugging off

13/044/2013 22:44:25 - INFO - For 2011 devices line, be sure you are not in MTP mode

I can't get into flashmode, what should I do now?

The phone can't be powered on, so there's no bootloop

Let the phone discharge for some days til it is a dead battery? how can I know it is a dead battery?

When he brought it to Sony Center, they said it must has its mainboard replaced and it's really expensive

It still has red led and it's bootloader unlocked, I guess the kernel has malfunctioned, but how can I get into flashmode, I used rubberband trick but it's no use :(
[Sony Cross-Device General] Captain Droid:
Sony center people dont know what "bricked" means. Its the kernel.

You do the wall charge for 6-12 hours. You will be getting the red led. that means its charging on low power. so it will take some more time to charge. Then after that, keep your flashtool ready to flash the kernel of the stock ftf. dont try to flash the whole rom, it will fail. flashing drains hell lot of power from phone.

After u have a succesfulll flashing of the kernel, charge again for sometime , 1-2 hours.

Then Ready the flash tool with stock ftf.

Hold the button for flashmode in your phone. And u will have to hold it for some minutes.( 5-10min).

The phone will start flashing.

If the phone power off while charging. put it for wall charging again .

Its a time taking process, so be patient. Your phone can be recovered.

PS: Check OP Post 2, to understand more about the situation you are in .

Gosh..Trying to install LCD Dencity app and after reboot it just stuck at XPERIA word..

No respond after soft reset & hard reset..

Do I need to wait the battery die?..Thanks..
[Sony Cross-Device General] Captain Droid:
No response in the sense, you don't have access to flash boot or flash mode ??

You can wait for the battery to die , or you can dissemble the phone to disconnect the battery cable & connect it back.
[Sony Cross-Device General] kumbangdesa:
Yap..I've tried to enter flashmode or fastboot using flashtool but it's not work..charging also didn't work..

I think just waiting battery to die..dissemble the phone look very difficult and risky to do it..

Thanks..
[Sony Cross-Device General] Captain Droid:
The same happened to me, my kernel was damaged, so i disassembled my phone.

Its not risky.You need to reset your phone before you can do anything & the best way to reset is disassemble.

Check in youtube
[Sony Cross-Device General] kumbangdesa:
I'm already look at the video before this and I'm not sure can do it..I'm afraid if accidently cutting the wire or scratching the motherboard..:o
[Sony Cross-Device General] Captain Droid:
No bro there is no wires to cut, and motherboard is covered. So no possible way to damage any other parts.

When you open the back cover, you will see again one small thin layer. Unscrew then & remove you will see the battery cable.

You can do it man. There is first time for everything. Trust if u successfully unbrick your phone, then in future you will not be worried because you will know what to do.
[Sony Cross-Device General] kumbangdesa:
Thanks friend..:)

Edit : My Ion completely out of battery after 7 hours..I'm charging to full 100% and flash stock ICS..Install Stock .211 kernel + twrp again and recovery the previous rom..Now everything going alive again..:victory:0

I'm really don't like built in battery..:rolleyes:
