You can root without unlocking the bootloader and without voiding the warranty by using doomlord's zergRush easy rooting toolkit on firmwares that are no later than 4.0.2.A.0.58 - that is to say, you cannot root 4.0.2.A.0.62 using zergRush. As for kernels, you have to unlock the bootloader and that voids your warranty.

[Q] How to backup my stock rom

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.

Some questions about rooting and warranty

Hello, I got an arc s and I am new to android.
I decided to root my phone, but i want to know how to restore the phone to unvoid my warranty so i can take it to repair before rooting it.
Can I simply restore my phone using seus or pcc?Or i need to unroot it? Also, can i use ota or computer to update my phone after rooting?
PS: I know that rooting will not void my warranty but it seems that i can't take a rooted phone to repair in Hong Kong. Sorry for my bad english .
You could downloaded a pre-rooted firmware and flash it on your phone which is the easiest thing to do

I need to have an unlocked bootloader to flash it, right?
I am going to follow this tutorial since I don't want to unlock it.
Thanks for your reply
if you want to unroot then update phone via seus if you are on locked bl(i guess)

Root MJ9 without triggering KNOX

Hi everyone,
I sent my Note 2 for a repair through the warranty, and I just got it back updated to 4.3 with N7100XXUEMJ9. I found this thread:
http://forum.xda-developers.com/showthread.php?t=2500823
but from what I understand, it seems it can only work if I am on a lower version and then upgrade to MJ5 and root.
So what I am asking is, does anyone know how to root a Note2 already on MJ9 without triggering KNOX?
Or can I just downgrade to MJ5 and follow the thread instructions? although from what I read I cannot downgrade without triggering KNOX. right?

Thanks for answering.
I stumbled upon that thread before, but it's only for rooting. I guess there's no chance to flash a recovery and custom rom yet, is there?
Anyway, if I root as described, how can I unroot and more important, reset the counter to 0 and official if I need to return for the warranty?
Once you trigger KNOX warranty void, there is no ways currently to "reset" that status.

[Q] What should I do to not flash KNOX bootloader?

Hi guys, I'm getting this phone from someone and I want to know that if the phone came with 4.1 without KNOX bootloader what can I do for precautions to not flashing KNOX bootloader?
or, if the phone is came with 4.4 with KNOX bootloader how can I remove it? thanks.
The question should be if you still need to bother about KNOX? THe warranty is probably over and if you have lower bootloader, then flash MJ5 and ROM without KNOX and prerooted like OMEGA, which I recommend. If you have newer bootloader then just flash whatever you want and forget about KNOX

so there's no way to remove the knox bootloader right? So if I got the old bootloader, should I flash MJ5Patch?

If you get bootloader older than MJ5, flash MJ5 bootloader, it is the last one that works with 4.3/4.4.2 that is without KNOX. If you get it with MJ5, no need to do anything. If it's newer - you'll just have to live with the fact that Knox flag will be set to 1.... (if you want to flash custom ROMs)

Bootloader unlock?

Is there any way to unlock bootloader on Sprint S6 without tripping Knox?
If you acquire Root or install a custom recovery, you are going to trip Knox.
