Stuck On Sony Logo Help PLease

Hi Guys,
THis is the first time i am rooting a sony phone(previously used HTC and Samsung and rooted them without issues)
1. Rooted Stock ICS using DoomLord ZergRush Exploit.
2. Installed CWM installer for Xperia and installed clockwork mod
3. flashed http://forum.xda-developers.com/showthread.php?t=1526717
4. Wifi wasnt working so rebooted to recovery and flashed again.
5. Stuck on sony logo
have tried to get into CWM by holding volume down(number of times) and back button as well...
i understand being stuck on Sony Logo = Bad Kernal.. but i am stock kernel (bootloader locked)
how do i fix this guys... please help.

Just to confirm, are you stuck on Sony logo or Xperia logo?

stuck on the Sony Logo

Did you unlock your bootloader and your ment to rapidy tap the volume button down to boot into CWM
and its not a bad kernel, unless a kernel is ment to be used with the ROM
this is what you can do, for unlocked bootloader and rooted phone... Boot into CWM > hit "wipe data / factory reset", "wipe cache partition" and "wipe dalvik cache" <- in advanced settings > now re-flash the ROM (always best to make a backup before doing these things)

Did you follow all the instructions for rooting and installing CWM and the ROM to the dot?
Also, did you install the ROM via CWM or Flashtool?

Are you by any chance trying to switch on your phone while charging? Installing the CWM via the CWM Auto Installer causes the phone to go into a bootloop if you try to charge it while it is switched off or restart it while it is charging.

For rooting, just did what it had on the ZergRush instructions, CWM install was quite easy as well with the flick of a finger..
Flashed rom via CWM, It did boot ok the first time, but second time when i reflashed came this issue.
Only thing different between my first install and second is, I didnt format system partition on my second install? but i did do a full wipe
I did have it plugged in via usb till it got bricked, removed it just then and pressing vol key to try and get it into recovery.

Read the second part of my previous post. Are you trying to boot while charging?

Hi Sora,
thanks for helping..

now i do not have it plugged in

Is it still getting stuck on the Sony logo?

Hey guys still messing with my phone here, managed to download an ftf file and flashed the default ics on it..
thanks for the help.... it has booted now
are any instructions on how to root and get cwm so i dont screw up this time over again..

Did you flash ICS 4.0.4? As you may already know, the rooting method for locked bootloaders depends on the build version in Sony's case.

HI,
Thank you..
I'm sorry I'm still new about these things
I just can't flash it because my back-up is .img file..
And I don't know how to flash .img files..
Thank you again..
I've tried downgrading the kernel into .431 firmware (which is compatible to the theme that I tried)
but still, boot looping..
please help

What I did is that..
1. tried to flash a theme for .431 firmware
2. boot it using CWM v5
3. then, after rebooting the device, boot loop happens
I can't enter CWM on the sony logo (or I am pressing the wrong button)

Hi thank you..
I just did the flashing
But still, boot loops ..
I really don't know the problem :'(
Here is what I did to install that theme..
● Copy the .zip to your sdcard
● Boot into CMW
● MAKE A NANDROID BACKUP
● Did you make a nandroid backup?
● If not, go away from this thread immediately!
● Flash the .zip
● Clear Dalvik Cache
● Reboot
● For wallpaper, Xperia S lockscreen, deodex/supercharge/LED fix check post #3.
● Enjoy!!!
i really don't know if that clearing that Dalvik Cache caused the problem..
I really don't know
pls help ..

Did you even read the previous posts? These say everything how to fix your phone.
And if you got bootloop, doing it the same way will not make it any better, it will just result the same - bootloop!

dont use CWM v5. reflash to stock firmware, download 'x-parts' from play, and istall cwm with that app and see what happens

Hi (my first post at xda!),
I once had a nasty BootLoop like you have. actually, even worse - at some stage, the phone didn't start at all - AND usb wasn't responding... worst case scenario lol.
Be advised, this will bring you to clean stock unrooted phone.
- What you need to do, is restore the original rom+kernel (stock), using SEUS ("Sony Ericsson Update Service") software (download it).
- You'll need to connect the phone with a special recovery mode enabled, by plugging the usb cable to it while holding The Other Button (Back button) that gives A GREEN led light (this is NOT Fastboot mode that shows BLUE led light).
- After the phone is connected in that manner, simply follow the instructions in SEUS and let it download and flash the original software.
From here, you'll have a factory-new unrooted stock rom+stock kernel device, but you'll probably manage with re-flashing and restoring your Nandroid afterwards.
- Use this as a last resort, as it's what they call "The long way".
Get back to us with the results.
Mike.

It's not a special recovery mode it's the standard flash mode, but this is basically what you've been advised to do on the last page.

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.

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.

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.

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.

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)
