[Q] Xperia NeoL wont boot

Xperia Neo L has same hardware as Xperia Play. That is the reason I am posting this thread...
I have managed to brick my phone very well.. it won't show bootload logo itself..
I was in a JB custum Rom with Kernel..
First phone was not going into fastboot mode.Even when I press vol down button its taking to flashmode(green button)
So I flashed stock firmware with its kernel.. now also it was not taking me to fastboot.. so I did "adb reboot bootloader" phone booted into fastboot
then I flashed a JB kernel... then its gone... no lights turn on.. not even bootloader logo is shown....does any one has solution... or I better take it to sony for fix... pls help

Working
Its Seus who helped... I managed to flash stock now working fine...

first i'm sorry to hear that
umm.. as i know to enter fastboot mode you should press search button (not volume down button)
from your story its probably out of batery, so may be you can charge it a while or try it with another batery
btw have you try to reflash it with stock ftf??

Pressing once does not turn it on. You need to hold it down for few seconds, til it vibrates. Then you can release it.

I do this but wont power on. I dont know why.
Its recognized on my computer as qualcomm usb or zeus flash device.

It's soft bricked, you need to recover your phone with Sony Update Service.

You won't need to power on your phone for this. Install Sony Update Service on your computer and follow the instructions given.

Ok thank you I will test

I follow instructions but the window where there are instructions for connect phone no change
the phone is recognized as zeus flash device
update service say me

- hold back button and connect phone to the microusb cable
- still hold back button
Im hold the back button still 2 minutes but nothing appear

Its gotta install drivers automaticly. Now reboot and try again

Ok I will test, thank you.

To turn off phone, take out battery (just to be sure)
Put battery back in.
Follow instruction from sony update service.
Press and hold back button first. Dont release
Now connect cable.
Should work now and update service will do its stuff.

Thank you guys but
It work, green led and updates loading, phone detected as s1boot download.
I unplug the phone and hold power button until vibrate but nothing
Now when I plug phone on the pc, the computer detect qhsusb_dload device
what is the problem ?

That is strange. I am running out of ideas to help.
Last idea is to use Flashtool and flash a stock GB/ICS rom.

I forgot if flashing by flashtool requires to have unlocked bootloader.

Ok thank You
I will unlock the bootloader and then flash the phone

[Q] Xperia Arc S Lt18 died after flash boot.img

Hey buddies,
I have a big issue:
My Xperia arc S is rooted, I did the bootloader unlock with sucess, and, when I flashed the boot.img (I had sucess by ADB), after ask to "fastboot reboot' my device died :/
It can't be recognized anywhere (USB-PC, wall charger, vol up + usb but it doesn't enter in fastboot mode), it doesn't turn on anymore.. When I hold "power button + vol up + vol down + camera button it's vibrate, but nothing happened in display. I had just this feedback.
Any ideas?
Thank you!

Try using flashtool. Hold down "menu" key and plug your phone into the usb. You will get into fastboot mode and then flash custom kernel.
After flashing kernel get into CWM recovery. Once you get in there its easy to install the ROM you want.
Make sure you flash kernel according to the ROM you selected or else you will get bootloop.
CHEERS!!

same issue

No, you don't need to press power button.
Switch off your device(which is already in your case) then while holding down the "menu" button on your phone, plug the phone into your computer via USB cable. If blue LED lights up, means you have successfully placed your phone in fastboot mode.
If its not working then probably your device battery is empty. You will need to charge it bro. And this might be a big problem unless you have got one more arc/arc s.

Sounds like the chargemon has been corupted of wiped! That could explain the charging issue. Try vol down & plug in usb for flash mode(green led if good) connect to pc companion and repair phone, or flashtool and the rom of your choice. If not it may be a jtag job im afraid n thats pricey!!!

You are on the right track. Press and hold the volume up+power button until you get three vibrations. Then use Flashtool and flash the latest stock ftf file. When prompted to connect your phone, connect it while holding the volume down key. You will get a green led on your phone and the flashing process should start. Once it is complete, disconnect your phone and start it normally,

But your phone just connect with your phone by flashmode,not fastmode,you want to gonna fastmode,you need to shutdown your phone,and press VOL+,and then connect with your computer.Just do as what forumer said.Don't mixed.If you want to install the customer rom,you need to unlock your cellphone.Remember you need to go the following step:
1,root your phone,
2,unlock bootloader(fastmode)
3.install the recovery.(fastmode)
4install the kernel from the rom.(fastmode)
5install the rom.(recovery)
6reboot into the phone

power&VOL+ gonna fastmode,power&VOL- gonna flashmode.Seams the driver is different.If you unlocked the bootloader I think your fastmode driver is installed.And whatever of mode you went in,you must power down your phone.not restart.

I didn't get it but i tell you no response with any other buttons neither vol- or power on by itself

as i told you ( power & vol + ) ----> goes into flash,mode !!!
