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.

What i know about rooting is that in order for it to be appreciated, you must unlock the bootloader. The thing is, i havent updated my software yet to 2.3.4. My question is will rooting and unlocking bootloader affect if update comes into my location? This is the reason why im sticking to stock rom now.

You can root and ota while keeping root without unlocking bootloader using Gingerbread or the new zergrush exploit. Search the forums. If you want to install custom roms (cwm or cm7.1) and kernals (overclock) then you need to unlock. But will not be able to update ever unless you relock

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.
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.

you can root your phone using This method .
I'll be going on a trip to China soon and I need to unlock my phone. I have tried unlocking my phone with the help of this post, but unfortunately it didn't work out. I read that I need to be using the stock rom for the unlock method to work.
My question is: if I unlocked my phone on the stock ROM and then restored to a backup with Clockworkmod, would my phone still be unlocked?
Also does anyone have a link to good stock based ROM that I can use to unlock my phone?
Any stock based Rom will do it, even the plain rooted stockones. And once it's unlocked, it stays that way until you relock it. Flashing a Rom shouldn't cause you to relock
Dear members of XDA!
A few quick questions here:
If my bootloader remains locked from stock:
1. and I downgrade to a previous stock android version rather than 4.4, will I lose BE?
2. if I do lose it, and then flash the last stock version, will I recover it?
If my bootloader was unlocked, I know that I should lose BE, BUT:
3. if I install a custom rom, don't like it, go back to the latest stock, and after everything's finished, relock the bootloader, will I recover the BE?
Thanks in advance!
1.nope
2.you will lose only if you unlock BL.
3.if u have TA backup, you can relock BL and recover BE by flashing stock ROM and restore TA.
