4.0.2.a.0.62 arc s root

hi i gust wanted to know about 4.0.2.a.0.62 arc s root
is there any way to root 4.0.2.a.0.62 devises ?
their is just unlock ur bootloader then ! im satisfied .58 il wait for ICS to come
or you can downgrade to .42, and root. I did the same thing, and removed few built in apps that I don't use, and every morning I get 200MB of free RAM, and in normal usage I get 170MB free RAM + the phone got a lot faster than it was on .62
But I dont want to unlock bootloader and lose the warranty and OTA update

Downgrade to .42 build and root.
There are some root methods for .62, but idk. Just look and search.

I did it just few minutes ago and no need unlock BL
1. Flash to 42 or 58 firmware by flashtool. I download from below linkhttp://forum.xda-developers.com/showthread.php?t=1357841
2. Root ur phone by flashtool again.
U can change the CDA before use US or PCC then back to orginal 62 FW.
Cheers
PS.sorry my poor english
Solved
1. Unlock the Bootloader
2. Install Doomlord Stock Kernel 1.6 ( Pre rooted)
3. Install .62 stock Kernel from .ftf file (Root remains from Doomlord Stock Plus Kernel 1.6 even after installing .62 Rom kernel agian)
4. Re-lock the bootloader with the help of Flashtool.
5. You have Stock ROM rooted and with locked bootloader.

Download Arc S LT18i (4.0.2.a.0.62 Offical ROM) : http://www.mediafire.com/?6fs6iry9spv78mb
You can install Arc Rom on ARC S by some tweaks but it makes your ARC S slow as the default CPU speed in ARC is 1 Ghz and our ARC S is 1.4 ghz by default.
Download the .ftf file from the above link and install it through Flash Tool.
@jaipurwasi80 Thank for answer and help.
I think the problem(arc s as arc(cpu)) can fix with overlock and upgrade 1,6 or 2,0 ghz,cant it?

I have used the same file for my Arc S( LT18i) and its worked fine for me along with the Latest Flash tool. I hope you are using the .ftf file in Flashtool and your phone in flashboot mode.
OR
Go to www.wotanserver.com and download its client on your PC to Install any Offical Sony Ericsson ROM. You need to make a free account on the site and while installing you can choose to install 4.0.2.a.0.62 offical ROM.

[Q] How can I revert my Arc S back to stock Kernel, ROM (2.3), etc

Hello XDA, sorry if this has been asked before but searching around for a solution is giving me a headache because of all of the technical jargon and not knowing what to do.
I upgraded my Arc S to ICS, made my kernel that of DooMLords and then installed Arconium ICS. I'm just having a lot of issues with it, such as my music skipping, games freezing and my phone crashing up to two or three times a day which is just appauling.
I'd rather just go back to Gingerbread and have my phone function well rather than enjoying the new ICS features and layout.
Could someone please tell me, or link me to a guide, that gives simple step by step instructions on how to get back to just a completely stock 2.3 Arc S?
Download .42/.58/.64 ftf file.
Flash it using flashtool..

My wife is the same she won't let me near her phone... In her words,I am always needing to restore backups why? Because of some mod update etc.
As regard your main question it could be because of the phone carrier, not releasing an update.
I have t-mobile arc and they haven't updated to ics according to pc companion always shows I have latest software, but flashtools will upgrade if you can convince her to let you.

You can read about it here: http://androxyde.github.com/Flashtool/

I would like to know if its really true and if not which ROMs are available for my phone. ?*
thank you , please suggest me a way.

According to GSM Arena, Xperia S and SL seems to be the same. They got the same chipset, same GPU and pretty much the same hardware. Only a few minor things seems to differ.
But I find nothing about Xperia N (Misspelling? Typo?)
http://www.gsmarena.com/sony_xperia_sl-4894.php
http://www.gsmarena.com/sony_xperia_s-4369.php
But I cannot promise it would work. On a logical level, these devices can differ. Even to a grade where a kernel might not be able to fully initiate. (With a kernel panic as a result)
Addresses, busses, partitioning scheme , flash ICs, and other stuff can differ. It could be a completely different board, even if the same chipset, GPU and other hardware is the same.
The only real way to be sure would be to compare these two devices side by side on the inside.
Is it worth the hassle?
One could try to flash a S ROM on the SL device, or the other way around, but make sure you can recover from a paniced kernel first.
One way to recover from a such state would be opening the device, and hardwire JTAG connections, if there are any.
I don't have too much experience recovering from seemingly bricked devices. different devices behave differently. Some have a simple preboot mode which one can use the USB connection to transfer firmwares over. Even when a kernel is malfunctioning completely. Others just become hard bricked, requiring using JTAG connections or similar hard wiring to recover.
Ok then cn u suggest a good ROM fr xperia SL alone? I mean if u cn tell it would b helpful. I tried to find one but couldn't. If not then ill hv to try doing what u said.

You went too complicated Mate. Xperia S and Xperia SL are exacty same, bar some software changes. No need to perform jtag and all to restore, You just need to flash back the stock firmware.

Yes I'm absoulutely sure. I own a Xperia SL and have been used all of the Xperia S ROM's on it. Mokee is good, just use a stable build, not a nightly/release one. You can Google for it. But for installing a Mokee ROM, You need to unlock Your bootloader since You require a custom kernel.
Sorry I m kinda new to routing tell me about custom kernel ?? I have already rooted my device by using flashtool.

First copy the ROM.zip and gapps for that ROM to phone.
Then on PC, extract the boot.img from ROM.zip.
Connect Your phone to PC powered on. Using fastboot, flash the boot.img to Your phone with following commands:
Code:
adb reboot bootloader
fastboot flash boot path/to/boot.img
You will find fastboot.exe in "C:\Flashtool\x10flasher_lib"or where ever You installed the flashtool.
Then Your phone will have a twrp installed. Just boot into twrp, and flash the ROM!
Don't forget to wipe 'data','cache','dalvik cache', 'system' before You flash the ROM.
Then after flashing ROM, just wipe 'cache' and 'dalvik cache' and flash the gapps.
Important: This will delete all Your apps. But Your videos, images, music will be safe as it is stored in 'sdcard'.
DON'T WIPE 'sdcard' AT ALL.

1.7 is not minimum, it is the maximum frequency Our processor can handle. And taking it to 1.9 would kill the battery and phone or render it highly unstable. You won't feel a lag at 1.5 ghz at all, trust Me. Been using at 1.5ghz, the phone doesn't feel slow at all and definitley faster than stock ROM's..
