[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??

[Q] Phone in not starting after installing custom rom

I have installed CyanogenMod 11 custom rom to my Xperia Arc S. After flashing boot.img through flashtool, device got shutdown. Till now everything was fine. But after this the tutorial said to start the phone and after the phone vibrates, start pressing the volume down button. I did the same. But after vibration, phone is not showing anything. It shows dim light on screen but its not showing either the logo nor its starting. The LED light on side turns to purple but nothing happens after that. I did this with every button but its not starting. Pls halp me out....
Thanks...

Tell more about this. How did you do it, what happened, what buttons did you press etc etc.

Yes. I have installed kernel for it via flashtool. Initially after doing this it was not going to recovery mode and also it was not getting connected to flashtool. But now it is getting connected to flashtool in fastboot mode. So tried to flashing with 10.2 version, it showing finished but again the same problem. Its not going to recovery mod.

as in, HOW did you flash the kernel exactly. Dont just say you used flashtool, how did you use it? What combination did you use to get into fastboot? Any errors in flashtool? How did you boot into recovery (I.e. which keys did you press) and does the LX kernel logo even appear on boot?

First check does that kernel has built in recovery...If nothing works,to get your phobe to work flash stock .ftf file with flashtool.
Do you have unlocked bootloader?
And try one more thing,when you turn on the phone start pressing volume down (-).)!

I think i have the same problem as OP.
I decided to try out LegacyXperia CM11 and installed it yesterday. It went well, but it is still kinda buggy so i decided to go back to besttt's Slim Bean. I copied rom files on SD card and went to flash kernel (darkanzuEOL). I flashed it through Flashtool like every other time and it went without errors so i proceeded to boot into recovery so i can flash the rom. This is where everything stopped working normally. After i power on the phone and press voldown to enter cwm it just gets stuck on cwm loading screen. If i dont try to get into recovery it just bootloops. I tried several kernels i have on my HDD and always the same result.
I'm downloading stock img to flash and see if that will help. will let you know what happens.
EDIT:
Stock img worked, now i'm back on slim. Only other thing i changed ( which i think is the cause) is i used original sony usb cabel instead of my Nexus 7's i used originaly

did you unlock your bootloader? Unlocked bootloader allows you to flash the custom kernel for your phone and it is vital for booting up custom rom like cyanogenmod, paranoid android, slimbean, etc. Every rom need a correct kernel for it successfully boot up, for example, if you are using stock rom(original rom from sony), you will need stock based kernel for it .Ok, now get back to the topic, you said that your phone had boot failed after installing a custom rom and only sony logo shows up. That means your kernel is stock kernel and not match with your rom so thats why your phone wont boot up. You will need to flash the boot.img included in your rom.zip before flashing the rom. Now try this tutorial to recover your phone http://forum.xda-developers.com/showthread.php?t=1849170

That happens to me too. Try waiting for it first for several minutes. And if takes too long, maybe more than 5 mins, try pressing power+volUP until it vibrates three times. Then power it on again. And also this happens too while my phone is charging.

brick fone means wrong kernel flashed and when you boot up, it STUCK in a loop withing kernel! actually the phone is ON but you can only see some gray screen in dark. its ON and stuck in kernel.
now removing battery will switch of the device for your to connect in flashmode again and flash proper frimware !!
but then......... xperias don't have REMOVABLE batteries (anymore)
now! either you can put it on wall charger for 1week and let the mobile get it in charging mode slowly! and one fine day i will come back to life
ORRR you can do something different /creative
Press the POWER button + VOLUME UP button for 15 seconds....
---------- PHONE will VIBRATE 3times---------------- on second VIBRATION------ RELEASE BOTH YOUR FINGERS IMMEDIATELY!!!!!! -------- the phone will shutdown.... now connect again in flashmode (green light) and flash the proper firmware
and yes, please be carefull before flashing any kernel! next time!
