[Q] Sony Xperia Arc S won't boot up.

When I try to boot it up (using the power button of course), the LED above the USB connection place flashes green, and the phone vibrates once and does nothing.
Any help would be appreciated, thanks.

Your question is too general. Did you do anything to your phone?

I found the issue; can't use SEUS after you unlock the bootloader. Thanks anyways! All I did was flash a rom that relocked my bootloader (?? don't know the terms), and then run SEUS again.

you cant relock a bootloader with a rom.. you need help fro this thread. download a ftf firmware and flash t using flashtool so that the phone boots p and then check the bootloader status .....later depending on it, flash a custom kernel and rom (optional though recommended)

Well, there are scripts available that can relock the bootloader...
Link-in's method works too.

Whoops, guess I meant I flashed an FTF... lol. Something I found on YouTube.
But yeah, I've run into another problem; while rooting the phone (using this guide over here: http://forum.xda-developers.com/showthread.php?t=1683957), I think I've bricked my phone again. I didn't enable USB Debugging and Unknown Sources, so it got stuck at Daemon Started Successfully. Haven't been able to boot into my phone since. Sorry if this problem has been solved before, wasn't able to find the solution while searching that thread.'
EDIT: ...sorry again, managed to stumble my way through and revive my phone.

Epic Failure while trying to flash/root my ARC ICS 4.0.4

So today after watching tutorial videos and reading about it I finally made my mind and decided to flash/root my xperia arc. The build no of my stock was .431 now what I did was download the '.431 ready to root ftf' and flashed my phone, now when I tried to root it it gave me several errors mkdir failed for tmp, File exists and rm failed for *, No such file or directory and to make thing worse the memory card messed up and I had to format it and lost all the data. Now I've recovered the phone using pc companion but I failed very badly
I have no idea what exactly did I do wrong?

Not a clue, the memory card shouldn't have been affected so god knows. Just start over.

is there any other way of rooting my device? like if I unlock the bootloader will it be easier to root it? and how do I go about cfw/kernel/mods in a unlocked bootloader?

Read the stickys, and the individual threads for instructions.

Go to setting after flash the ready to root 4.0.3. Click at xperia. Click connectivity. Click USB connection mode. Choose MSC. The default is MTP if i not mistaken. Then root your phone and flash back 4.0.4 kernel.
This method i using when i root my phone last week. Before that it was giving me so many error.
Im on LOCKED BOOTLOADER while doing that

Yes, after unlocking the bootloader flash a kernel, and then install a custom rom that's pre-rooted. Much easier way if you don't mind not sticking with stock.

what kernel and ROM should I get?

Normally I use the Arcknight kernel (Get version 3.5.1 or 3.3 because 3.6 is broken), but since Sony released the new .587 build I'm sticking with this kernel for now.
Now with Roms I suggest you go with this one its really good .

Okay I just rooted it sucessfully but I kept the bootloader locked.

How do I flash Arcknight 3.5.4 on my locked bootloader?

So how do I go about getting 'Xperia Ice Bean 4.0.4'?
If that's not possible then can you please recommend some good ROMs for locked BL if there are any?

If you're going to root then you might as well unlock the BL. If IceBean needs a custom kernel then you can't use it, if not follow the instructions.

I unlocked the bootloader and now running cyanogen mod
however the usb transfer speed is rather slow, around 2.5mbps?

[resolved]How to root stock ROM?

I found Jelly Sandwich too slow so I down graded to this stock ROM. Now when I run the root for scripting I get a bunch of permission denied messages and it doesn't work. How can I root the phone? I can't unlock the boot loader.

Before asking questions that have been asked a thousand times try searching in future. how to root arc

you have to download and flash a rootable ftf. Here's one for arc s

According to this thread with a locked boot loader custom kernels can't be flashed. Is it that you can flash stock kernels but not custom ones?

yep. stock kernels you can flash because they're stock - stock ics already uses them. custom ones, you can't.

If you hAve Xperia pro then follow the below link
http://forum.xda-developers.com/showthread.php?t=1801480
And if not pro then follow the procedure and use you phone kernel.
If I helped you press thanks.

btw, which version of JS did you find too slow? you could try the latest version because it comes rooted already

For those that have come across this most recent but thousandth "how to root" thread, you'll find the solution in the first few results of the link I posted on page 1.

8.0. I don't think I can try the latest version because how will I install CWM without having root?

As soon as your bootloader is unlocked you can flash any kernel which mostly will have CWM included.

[Q] Fastboot / Flashtool little problem.

Good day..
I have a noob question , im just a beginner.
I have Xperia Arc S . Id like to install CM10_anzu but when I flash the recovey namely "boot.img" from the zip
using fastboot or flashtool it gives me "Device needs a root" error etc... But I am definitely rooted.
What am I doing wrong here. ?
thanks ... Good Day.

I think you need to unlock your bootloader to use fastboot. I guess thats problem, but maybe someone smarter will answer you correctly

Thank you for a suggestion.

Don't know about the arc but on Xperia Play boot.img was not working on CM10 so I just used another JB Kernal and that worked a treat.

Fixed!!! Using the Sony update service.. What a relief!! Do we need to flash the kernel or its done tog with flashing the ROM?
Besides unlocking boatloader, install cwm, root the phone, what else need to be done before flashing?
