Hey guys,
since i flashed back to and older version to root the phone and then upgraded again, everytime my battery is empty and i plug in my phone in to charge, it ends in a bootloop. But when i press the back button to get into the recovery and then boot the phone from there it boots normally.
Someone knows what went wrong, when i rooted my phone?? :good:

here is a list of ROMs for your phone be sure you have Xperia Arc S not other phone never flash a ROM that is not for your phone because you can cause hardware damage to your phone
i cant install a custom rom, cause my bootloader is locked.
edit.:
can i install arconium (http://forum.xda-developers.com/showthread.php?t=1565475) cause it only requries a "stock kernel with CWM???
A unlocked bootloader is only usefull to install other kernels, but because this rom is compatible with a stock rom, i think i dont have to unlock the bootloader, right? :cyclops:

i can unlock, but i dont think it is a good idea for a newby like me to unlock it.
I rooted my phone, cause i wanted to install other fonts and wanted to delete some apps, which were installed, and to customize some

It seems Acronium requires an unlocked bootloader
for your first flash I recommend to install a stock-based ROM just leave bootloader as it is if you just wanna do this way then use a laptop when flashing /unlocking bootloader cause every failure in bootloader results in a dead-phone then only service tools save your phone -your phone is bricked
so search in that list for a ROM that is stock-based choose one with good howto instructions

ok thank u
Can you recommend me a fast rom which is working with a locked bootloader, cause i dont want to risk to install a rom, which is not compatible with my phone, and then my phone is broken ..
So if something goes wrong it is NOT possible to restore with CWM recovery?
here some information about my phone:
baseband-version: 8x55A-AAABQOAZM-203028G-72
Kernel-version: 2.6.32.9-perf [email protected] #1
android: 4.0.4
build number: 4.1.8.0.4.31

Ok, but why do you think unlocking bootloader isnt a good idea (cause of factory reset)?

hi guys .I have a V500,and I had flashed the TWRP on my device. And then I flashed a custom rom such as cm11. But ,in my opinion ,many phones flash roms must unlock the bootloader first . and then flash the recovery etc. But why our v500 don't have to unlcok the bootloader ?
Does LG provide the offical bootloader unlock service? Thanks.:angel:

Lg make their devices with locked bootloaders in contrary to asus nexus for example who allow you very easily to unlock the bootloader. Developers use a hack named loki to bypass the bootloader and allow us to flash custom roms and recoveries. Thats why you see a message if you re on a custom rom everytime you open your tablet, it means that loki is working fine at that moment. If we had unlocked bootloaders we wouldnt see that message as there would be no need for loki.

Installation Steps (Warranty can be restored whenever you wish)
-------------------------
Before starting your rom flashing journey it is always better to have Flashtool (latest -by androxyde) installed in your PC and your stock rom handy ; incase of any mishappenings.
Type *#*#7378423#*#* in your phone and see if your bootloader status is unlockable under service-->Configuration. Procede with below steps, only if your device is unlockable.
It is important that you follow the steps in order
1) First step for installing a custom rom over a mobile with stock rom is to backup the existing state of bootloader .Usually warranty will get void if any modification is done to bootloader. The below tool ensures that it takes the backup of existing state of bootloader when device is under warranty.
Goto
Backup TA for Sony Xperia (This tool helps you to have a )
http://forum.xda-developers.com/showthread.php?t=2292598.
Download the tool.This tool will backup your DRM Securtiy keys . Successful backup can only be taken after the existing stock rom is rooted (Use towelroot application if your device is not already rooted) .Root it first then follow the process given in above link .
Once this is over , u will have a backup of the existing state of bootloader/TA partition (If you later wish to move back to stock rom from custom rom use the same tool to restore the backup you have just created.This means you will get your Warranty back);
2) Goto this website , follow the steps and get your unlock code via e mail.
Use fastboot mode to unlock your bootloader (Make sure that you have already backuped your existing DRM keys-Step 1).Follow it fully to unlock your bootloader
http://unlockbootloader.sonymobile.com/unlock/step1
3)Download any custom rom zips with recovery, for your mobile from xda developers forum and have fun.Extract boot.img using winrar or winzip .
Flash boot.img via fastboot mode
fastboot flash boot boot.img
fastboot reboot
4)As the device reboots, when you see your LED glow press volume up or down. It will take you to CWM Recovery or TWRP recovery based on the rom that you have downloaded.
5)Just install the custom rom(*.zip ) from within the recovery.
What if that i already have the custom recovery?
So, just wipe data, dalvik, and cache, then flash the zip?
That's it?

Absolutely right. But before installing an custom rom in the first place i hope you have already backed up your DRM keys for warranty purpose(as mentioned in the guide) since if you unlock your bootloader without backing up your DRM keys, DRM keys might be lost forever .

Can i backup my app on stock rom then restore it to a custom rom?

Sure. Easiest way to do it is by using an app called, 'Titanium Backup Pro'.But you have to root your stock rom first for this application to run(Use towelroot if you are yet to root).Except for sony proprietary apps like walkman,Album,etc (will run only on stock rom as they use sony developed system libraries/API'S) other apps will get restored/run fine on a custom rom.

its in the OP....on the phones dialpad, type: *#*#7378423#*#*
then look in > service > configuration
it should show the status as "bootloader locked", "bootloader unlocked", "bootloader unlockable" or "not unlockable" (sorry wording may not be exact, but you'll get the idea)

no.. i mean, how to know if my bootloader is already unlocked or not?
Anyway, what happened if i flash it without unlocking it first?
Sorry, did you type that in the phone and check the status? That's where it will tell you if its already unlocked or if its even unlockable at all.
Do not try to install a custom ROM on your phone if it is not unlocked! Your phone will not boot.

Thanks to @ foomanjackel for answering your questions.Regarding your 2nd question, 'Experience is the mother of invention'.Why don't you try and see what happens...just kidding.Couldn't resist it. Practically speaking of you install a custom rom with an custom kernel on a locked bootloader you will hard brick it.It will not boot and chances are that you might not be able to goto flashmode or fastbootmode anymoreto repair it.Reason this happens is that both your recovery and bootloader resides in the same partition in your mobile.If you try to install custom kernel on a locked bootloader in every probability, it not only corrupts your existing stocks kernel but also might corrupt your recovery leaving u helpless.
Theoretically, You should be able to install any custom-stock based rom on a locked bootloader (which runs exactly on ur stock kernel).In other words a custom rom which doesn't come up with a custom kernel but based on your existing stock kernel should be able to run on a locked bootloader.But my advice is you do not risk it.

If you get this message "Bootloader unlockable: yes" then your bootloader is still locked.

I suppose it won't.I don't see the reason why u want to unlock the bootloader unless you want to install a new custom rom.
i accidentally switch off and on (oem unlocking radio switch) from developer option my bootloader is unlocked and custom rom is instelled is this will effect my device ?? bricking or any thing

There are valid reasons to lock your bootloader, but it shouldn't be done with unofficial software (a Custom ROM).
When the bootloader is locked, only signed software is allowed to boot, so only official ROMs can boot.

Correct
why would you want to loick the boot loader after a custom rom is installed to begin with?
