I have some question about this.
I want to o/c my xperia arc and for this i have to download another kernel, like doomlord kernel, but with the coming of ICS update (official) I wonder if i could get it if I change my kernel and/or my bootloader ?
If your bootloader is unlocked then do install the official update, (over-the-air or pc companion) because your phone will become bricked.
However you can Re-Lock your bootloader first then install the update.
to answer your question, you can only change the kernel if your bootloader is unlocked.

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.
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
Sent from my Xperia Play using XDA
then.. you need to flash custom rom that support autoroot
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

you can root your phone using This method .
Device: Sony Xperia M Dual (C2004)
OS: Jelly Bean 4.3 (15.5.A.1.5)
Rooted, bootloader unlocking allowed but locked yet,I have the code.
So I want to install custom ROMs which need. Now to flash them I need TWRP.
To get TWRP I need to unlock my bootloader, right?
The thing is I don't have the bandwidth to download the stock ROM to flash after unlocking the bootloader as it is around 700 megabytes.
So what I want to ask is whether is it possible for me to unlock bootloader and flash recovery directly and then flash the custom ROM?
Also considering my bandwidth limitations, how should I unlock my bootloader?

Unlock your bootloader... Its not mandatory to install stock rom after unlocking bootloader... You can flash cwm or twrp using adb... Google it... Then directly flash custom rom
Hi i would just like to ask something that has been confusing me for quite a while now. I've had my hydrogen for a week and ive unlocked bl, rooted now with a custom rom(rr rom 5.7.4 working great!!) I did not actually wanted to unlock the bootloader but to be safe, i followed the instructions.
so here it is, before mi max, I had a mi4i, an xperia, and a zenfone 4, done the same, root,install custom recovery, and flashed custom roms.. the only unit i unlocked bl was the xperia since i wanted to flash Official CM, (CM's comes with their own kernel right? so flashing them needs bl unlocked) but when BL was locked i could still flash roms, manual update, (ROMs that are meant for locked bl only). then with mi4i (locked bl) i was able to root, install twrp, manual flash updates, official roms, and custom rom (CM13).
The part where I am confused is, why do i need my bootloader unlocked if i was going to root,install twrp, and flash custom roms only on my max without touching the kernel? When in my previous experiences as long as i dont need touch/tweak the kernel, i dont need my bootloader to be unlocked.
Sorry for long post..
I hope my question makes sense
