[Q] [HELP] Xperia ZL (c6502) only shows Sony logo - Sony Xperia ZL

If someone interesting in History, read this :
How i root my device; when the first time i buy it, it's on .434, so, in that night, i update it to .253... Next 4 days, i want to root it, so i revert it to .434 by using a flashtool from bin4ry... It works, and nothing happened... And i feel something strange the superuser doesn't remember my Grant choice, so, i install SuperSU and i uninstall superuser.. Everything is work fine... The next thing i do is install modded google play 3.10.xx. It works... Then, i install go locker, when i press lock button, the screen is just flash, flash, flash, and the lock screen shows up... I think it's normal because of GO Locker... And then, i install modded google play again via lucky patcher, because on previous modded GP, it says no connection.. So, the phone is reboot and disaster happened...
So, i already root my Xperia ZL, everything is okay, then i install modded google play... And BAM ! It's happen.. At first, my phone only show sony logo and Xperia animation, after that it turn off automatically... I already flash rom for about 8 times, update it via SUS (Sony Update Software), nothing happened.. Now, my Xperia ZL can only show Sony logo and it turn off... BUT, i can turn it on when charger... When i charge it, everything is okay... When i unplugged it, 6 times later, turn off automatically... What should i do?
NOTE : My root is loss after i flash a new rom...
My firmware when i root it : .434, my current firmware : .253
And re-lock bootloader to download new firmware via SUS
Thx for the help :good:
*EDIT*
Xperia ZL version : C6502
Kernel Version : 3.4.0
Current Firmware Version : 10.1.1.A.253
Android Version : 4.1.2 (JB)

Xperia Arc Boot Loop

I own a Sony Xperia Arc (purchased on June, 2011) and it doesn't work anymore without any explanation.
When I turn on the phone, it appears Sony Ericcson brand and then, mobile network carrier brand, but then, instead of appearing home, it appears again Sony brand and an infinite loop goes on.
At first,I tried to solve the problem with the Sony tools like PC Companion and Sony Update Service.
Then, I tried to do a hard reset (back + menu and power), but nothing changed (the same bootloop).
What would you do now? Would be useful trying to flash some firmware? I have been reading posts about flashing firmware, bootloader unlocking and rooting Xperia Arc, but I don't now really what would be the best move now.
For your information, I haven't applied any kind of official upgrade before, neither I have tried to root the phone or flash any custom firmware, so I had my phone as it came from factory (with Android 2.3.2). Moreover, I haven't installed any suspicious application, just typical apps like whatsapp and so on. By the way, the phone haven't suffered any crash neither wet.
I have attached the log I have taken when I try to turn on the phone (I get the same log again and again, at the end of the log it reports some problem with memory, I hope it's not a hardware problem):
Try using the Flashtool and report back. http://forum.xda-developers.com/showthread.php?t=1304634

Hi,
also have the same problem.
I have the same problem.
İ have lt15i firmware. Try to install lt18i via flashtool and something broken and aborted. I tried to install LT15i_4.0.2.A.0.42_(1247-1041).ftf via flashtool. It said flashed but said power on turn on unknown sources and devices. When i try to power on it boot loop in Sony Logo.
I try to use CWM mode. Wipe and flash some data. Couldn't find user data files. Installed a Custom ROM when a boot animation appear its boot again to SONY logo. what should i do?

In the end, I could fix the problem flashing the latest firmware with Sony Update.
Anyways, thank you very much for the advice

[Q] Xperia Arc keeps booting up SONY XPERIA repeatedly -need urgent assistance

Xperia Arc
4.0.4/4.1.B.0.587
Bootloader Unlocked and Rooted
Guys,tried installing a custom Rom Omega on the 3rd.Nov,a couple of days ago.Followed every word the OP on how to install.Aroma popped up and made some choices and then rebooted into recovery.When phone switched back on only the SONY logo was there and it kept on repeating.Made some enquiries from members.Was advised to flash original firmware which I did.When the phone booted up,this time SONY XPERIA and kept on repeating.Been all over the place searching for a way to overcome this problem.
Came across an article on google:Recovering dead/bricked phone xperia arc -in that article there is mention of taking the generic global 4.1.B.0.587.zip file and extracting it to a .tft file and flashing it onto the device.This I am unsure of as I have never come across a .tft file.I've been unable to go into the main screen to make any changes to enable USB Debugging,Unknown Sources and MSC Mode if need be to flash again because when I tried doing it again the process aborted.Even tried to Relock bootloader so that SUS or PCCompanion would recognize the device
so that I can be able to get out of this mess I created.Unable to find a solution.Need urgent assistance.
You have to download the .ftf file (it's in the zip) on to your computer and flash it by using a tool called Flashtool.
Also flash stock kernel back or advanced stock kernel.

[Q] Sony Xperia Lt18i Lost Root, Bootloop

I lost My root and cant see the homescreen in my phone. It stuck on boot animation every time i install the room.
Hot to fix it ??????
Plzzzzzzzzzz Help
:crying::crying::crying::crying::crying:
You are probably doing something wrong, if the issue occurs every time you install a ROM.
Flashtool or PC Companion and flash stock firmware. How? Search.

Bricked I Think!

Bought a broken Xperia play from EBay, got it working, running Android 2.2.3 I think with locked boot loader but I'm sure it was rooted as SU was on it.
Problem is Android market won't work so got CMW recovery working and tried to install Slim bean rom, on reboot after rom install I just have Sony Ericsson on screen and can't get back to recovery.
Any ideas how to get back to stock or custom rom?

If you hold down the search (magnifying lens) button and connect the phone to the computer, what shows up in Device Manager? You should see "Sony Ericsson sa0102" or something similar. Also, what model of Play do you have, is the bootloader unlocked, and do you have FlashTool (preferably v0.9.11.0)?
