After my update from .42 to .69 I lost root access.
Now 3 weeks later I can't work without root. So I decided to unlock the Bootloader on my R800i.
How I get then the root access? Is it already there when I unlock the BL?
Or is there anything to do then, to get root.
How can I update to ICS?
With SEUS or normaly with the phone? And is the BL then even unlocked and will I have root access?
And is there a german manual how to unlock the BL?
To unlock the bootloader go here.
For root the only way I know for firmware .62 and up is by flashing a pre-rooted kernel like Doomkernel.

To update to ICS you have to flash a ICS Kernel/ROM. I suggest you either CyanogenMod 9 or Sony Official Beta. To flash CyanogenMod download the package from the official thread, flash the boot.img with <<fastboot flash boot boot.img>> then enter in recovery and flash the .zip package that has to be on your SD card.
To flash Sony Beta follow instructions in the topic but instead of the original boot.img flash DoomLord Advanced Kernel to gain root access.

I just got my Arc S, and i want to check out few different custom roms. I was planing on rooting the device with Easy rooting toolkit, so the question is, how can i backup my stock rom and reflash it, if i ever need it for warranty issues? (Also maybe to get the official 4.0 update next year )
On my previous phone (HTC Desire) it was pretty easy, by restoring the Nandroid backup that i created after rooting the device. How about the Xperia? Is there something similar?
And while we are here, any suggestion for some stable custom roms for the Arc S? Thanks
If you only want to root your device, you can simply unroot the device.
But you don't really have to, when you update your device using PCC or SEUS, the root is gone.

If you decide to unlock your bootloader to flash custom kernels/ROMs, you have to relock it, when you want to update your firmware using PCC or SEUS.

And which custom ROM you like is your decision, but I'm still a CM7 fan.
I have root, if I want to return to stock ROM (without root) I can just use SEUS to update my phone and the root is gone?

If your bootloader is locked yes.
I rooted my arc with EasyRooting toolkit,
How do I know if my bootloader is locked or not?
Edit: I checked by the service info, it says
Rooting status:
Bootloader unlock allowed: No
I am guessing that means my bootloader is locked?

Yes, it is.
And if you root, it doesn't, mean you've a unlocked BL.
Btw, you can't unlock your BL using the official method.
If you still want to unlock your BL, contact Jinx13.

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.
....Worked like Charm for me on my Arc s (LT18i, .62 ROM)
thanks
so what is the differnt between .62 and .42
btw i root my .42
All the Rooting Exploits don't work on .62 ROM as of now......Hence either you need to follow the trick I have mentioned or else roll back to .42........However there is no significance difference between .62 and .42................I am waiting for Official ICS
There's a better memory management according to people here

hey folks,
I will tomorrow unlock my bootloader on my R800i, and I have a few questions before I do it.
- How to Root then? I will not flash a new kernel, I only want root, because the update to ICS is only on June 2012.
- How to flash? I read always don't flash via CWM only Flash via Recovery?
- Can I flash then a original ICS Update from Sony, because I can't use then the OTA-Update to ICS from Sony or can I lock the BL again, and then update OTA?
once u unlock your bootloader, u cant get ics ipdate.. u need to relock back using .ftf file with flashtool.. go n search.. im wondering what the point u unlock your bootloader without install custom rom or kernel
u can use superoneclick to root your phone.. i hope this help u
No I can't because I have .69 and this is unrootable.
Then u need a custom kernel mate... they are pre-rooted

hi..
i wanted to root and then flash a costum rom on a xperia arc but im not getting root first...i used 2 methods for the locked bootloader the doomlord v1 and the Root_Exploit_OneClick both of these show me errors and the phone cant get root,i turned off every another process in the pc and the antivirus and still nothing...pls help me to root it...it is with locked bootloader..
Edit( i rooted it when i flashed a ready to root stock ics firmware and then with one click root method)
first of all you cant install a custom ROM with a locked bootloader... and the reason why your not getting a root is that your on .62 firmware and you can only root on .42 firmware... (NOTE: android version 2.3.4)

i have this version 4.1.b.0.431...what should i do to root with this firmware?
You have ICS https://www.google.com.au/#hl=en&sc...qf.,cf.osb&fp=c72d84806ae8a6&biw=1366&bih=667 that should help you
y the way there are 2 ways to root .431(4.0.4)
1) flash the .431 file and then flash the stock kernel of .562 ftf(i.e flash 4.0.4 and the flash only the kernel of 4.0.3) and then use doomlord one click method
2) flash a ready to root ftf file that already has the compiled things together.
(by the way, why dont you unlock your bootloader? because if anything goes extremely wrong it can only be corrected if you have an unlocked bootloader. and unlcoking bootloader is not risky infact it can be reocked again it will give you more choice to choose from various roms and kernels)
and note these methods work on unlocked bootloaders only.
these threads will help youon locked bootloader

hey everyone,
I updated my Xperia Arc to ICS via the sony pc companion update. But how do I root this version? Should I go back to gingerbread and root it or is there a way to root it directly, without going back?
Thanks.
If you have firmware 4.1.b.0.431 for ICS 4.0.4 then https://www.google.com.au/#hl=en&sc...=667&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&cad=b or just search what ever firmware you have on google or xda
if you have ics 4.0.3 then u can root it using doomlords oneclick root method. if it is 4.0.4 then u need to flash kernel of 4.0.3 and then root and then u can come back to kernel of 4.0.4 by flashing just the orignal kernel again. or you can download a ready to root 4.o.4 ftf and then flash it on your phone using flashtool.

Does it void our warranty ?
Sent from my LT15i using xda premium
well i am not 100% sure but i think that rooting wont void your warranty. unlocking bootloader voids your warranty because, root does not remain if you flash another firmware however, an unlocked bootloader is permanaent irrespective of what ever you install on it.
this was my logic however, remember dev's have shown how a bootloader can be relocked. get more info from here http://unlockbootloader.sonymobile.com/
