Stuck on Sony Logo (help please)

Hi I think I have bricked my phone, and I am looking for some help please I rooted and intalled CWM on a unlocked bootloader Xperia Arc S lt18i
This morning I flashed Beautiful ics 4.2.1 via CWM after doing all the wipes date, cache,dalvik,battery and then installed the rom.
When my phone came back on no led lights flashed and the sony logo is stuck on the screen. I have tried going in to recovery by holing down power button and pressing the volume down button but it doesn't work. I have tried connecting phone to my laptop but it doesn't see it any more.
I don't know what else to try,
Any help please.

Best install stock firmware by using Flashtool (or flash custom kernel so you have root already) and start all over again.
Be sure you wipe everything before flashing a new rom.

I had exactly the same problem with this rom but with stock .587 fw on locked bl. Installed it using method for installing Ultimate HD rom (Wipe Data/Factory Reset; Mounts and Storage --> Format /System; Advanced > Wipe Battery Stats; Install zip from SD card) and it worked fine.

Xperia arc s not booting after flashing custom rom.have i bricked it?

I had rooted and installed HD 3.0.2 custom ROM on my son's Sony xperia arc s successfully and it was working well but the adventurist mind set to work and I wanted to try the jelly droid custom ROM.
I went to recovery mode via x tools and did the factory reset and formatting system.
Then I clicked install zip from SD card.it showed that update installed successfully then after around 15 minutes and no further instruction,I rebooted the phone.seems like I missed some step or something which I am not aware of.
now it only shows the Sony screen.I attempted going to the recovery mode pressing the combo keys volume down and power after taking out the battery but nothing transpired.
have I bricked my phone?
Is there any way I could bring it back to life?
would be obliged if anyone could recommend some steps to try and restart the phone.
thanking in anticipation

Did you flash the correct kernel for your phone? Ultimate HD uses stock kernel while the Jelly Droid should be using a custom kernel. You need to have bootloader unlocked to use a custom kernel. CWM does not work after flashing the update package as X tools installs CWM into /system which you just formatted. To be able to use CWM after changing ROM, use a stock or custom kernel that has CWM pre installed on it.

Thanks for your quick reply.it seems I did not flash any kernel or anything else prior to pressing the install from zip.seems a grave mistake on my part.
now that the phone does not even start up what could I do to recover the phone.
I am a complete novice and would request your good self to kindly suggest remedial measures to go back to the stock ROM or HD 3.0.2.The boot loader I think was unlocked before attempting to root the phone.the phone only shows SONY written on it.no turning off even.having to pull the battery to put of the screen.
Thanks n regards

To recover your phone, use Flashtool and install stock firmware to your phone with a correct FTF file. You can find the FTF file from the forum, just search.
OR if you have locked bootloader, then you can also use PC Companion to repair your phone.
Sent from LT18i with custom firmware by myself.

Since you have bootloader unlocked, I recommend that you repair your phone using flashtool, since it's a hassle to relock bootloader to use Sony Update Service. After restoring your phone, flash a stock kernel with CWM on it so you can still use CWM after changing ROM. If you want to go back to UHD, Jader recommends LuPuS kernel to use with his ROM.

First of all, calm down , i rarely see arc-s really bricked and not recoverables so ,in this case, the best metod is a thinking mind. Answer my questions.
1° Have you checked your bootloader if it's locked/unlocked or if there is possibility to unlock it ? There are a plenty of guides about it.
2° Please describe how you have installed the rom.
If you have the possibility to reach the recovery , you have to fully format the phone. Factory reset, format system cache and dalvik. Only after that, try to re-flash the rom.

My phone has the same problem. (Xperia Arc S) how do I get the computer to recognise the phone when it is in this mode? it won't do the volume up-blue light-usb thing

Can you get the phone in flashmode (back + phone to USB -> green LED)?

Are you even sure if it's volume up?
Flash mode -> connect phone to PC while holding down back button.
Fastboot mode -> connect phone to PC while holding down menu button.
Enter recovery(if installed) -> hold volume down button when phone boots up.

Did you flash correct kernel for your ROM? The ROM will not boot if the kernel is not compatible.

You don't flash kernel with cwm... Flash kernel using fastboot... Kernels will give you access to recovery...

PC Companion's repair option should work as well, try that one. If you wish to stick to Flashtool, then first make sure you got drivers installed.

[Q] Xperia Developers Please Help !!!!!

Hello Guys , this is my first post in here
I've just downloaded the 'Xperia Ultimate HD' rom v.4.0 and wanted to instal it on my xperia arc s
I do a factory reset in recovery mode and wiped cach , and because of my stupidity i forgot to wipe software:crying:
When i reobeted the device it freezes on the SONY logo and doesn't continue
I tried to connect the device to my PC via USB but nothing happend at all
the computer didn't see any thing
so what can i do now!! please help

Did you install a custom kernel? Or if you habe recovery installed? If so you can just boot back to recovery and start over.

Actually the phone can't load to recovery

Often when i instal a new rom the recovery is removed
I have to reinstall new recovery from Xparts

Flash your stock firmware via flashtool.... Then start over
Xparts is temp solution to Cwm
If you don't wanna lose recovery unlock your bootloader and flash a custom kernel

Don't worry it can be easily fixable ..
If your BL is locked then do this ! :
Turn off phone (pull the battery out then take back)
Install PC comanion softwer to your computer
When it is installed then select software repair
When it say connect phone the do this :
Hold the back button while you plug the usb cabel in !
Then follow the instructions in the PC companion than you finished !
If it is not work try to do with flashtool SEARCH for a guide there are many for it (for example flashing frimwares with flashtool ) !!
Sorry for my bad english /it is late night for me.. xD
Here a video for PC companion repair : http://www.youtube.com/watch?v=PiaFGbeGOr0

which build did you install it? if you did first install you need custom recovery from your rom and then you can install cm to your devices.
first you need FOTA Recovery for your primary recovery, see in this thread for installation http://forum.xda-developers.com/showpost.php?p=58515383&postcount=1
. i suggest you to install twrp version 2.8.7.0 and turn on your device, after that connect it to your pc via adb and do dd if command.
after complete, restart your phone and go to recovery mode and you can flashing safely without any worries again
if you have any question just ask me again

As you are on stock ROM, you need Stock Recovery, flash this.. now boot to recovery. install CM12.1...
(FOTA Recovery will not Work on Stock, because stock kernels doesn't support extract_elf_ramdisk utility. )

I tried this recovery. Nothing changed...my phone still crashes when the cyan LED appears...
But I've noticed that the Sony Update Center want to update my phone to 15.4.A.1.9 even if that´s the firmware that im using. I´ll try to find another .ftf and report if its working or not
Edit: Nope, still wont work

Xperia z5 premium bootloop!

So i've been trying to root my xperia z5 premium. I successfully unlocked the bootloader and then proceeded to following this tutorial ( http://techchomps.com/how-to-root-the-sony-xperia-z5-premium-e6853/ ) to root my device. It then led me to this tutorial ( http://techchomps.com/how-to-install-a-custom-recovery-on-the-sony-xperia-z5-premium-e6853/ ). I downloaded the stable supersu file and the twrp image ending in 22 and the kernel ending in 4va ( i think flashing this is the cause of my problems). on the page that gives you the link for these files there is another tutorial ( http://forum.xda-developers.com/z5-premium/development/e6853-root-unlocked-bootloader-t3255039 ). which i followed up to the reboot point in step 2. after doing this my phone is now stuck in a bootloop.
How do i fix this?

Does Power - Volume + pressed together for a couple of seconds does something ?
If it turn the phone off, try to flash a firmware via Flashtool, otherwise I don't know :/

Use the Sony software to do a factory reset. It's gotten me out of a couple of bootloop situations with my previous phones (Z and Z3)

So I can still enter recovery but thats it. I continued trying to install supersu but it would still never get past the Sony logo on reboot. I managed to restore previous function using a flashtool and a previous firmware version. I still want my phone to have root access though.. Thanks for your help regardless

same problem here , any answers?
