[Q] Rooting and carrier warranty

I need your help guys,
just got my Xperia ARC and i wanted to root it by this guide and i have a few questions:
i bought the phone from an Israeli carrier (pelephone if its matter) so in the guide i need to change the carrier firmware to the original firmware and i wander if it will void the warranty. also is there any way to change back the firmware after the change, if so then how? i searched and i couldn't find anything...
thanks ahead

The thing with Rooting a phone, is that you can root your phone and still the ¨stock¨ Arc is untouched after you have unrooted.
The flashing and rooting dont break the warranty by it self.
If you change from locked bootloader to unlocked.. The warranty is removed.
Easiest way to root is:
*Download*
3.0.A.2.181 Generic World: http://www.mediafire.com/?​y9s73andrl4bllc
*Use Flashtool to Flash .181*
Flashtool: http://www.multiupload.com​/7H4JT35B6G
*Use Gingerbreak after you flashed back*
http://forum.xda-developers.com/show....php?t=1044765
*After it have rebooted and active, go to settings and do a OTA over wireless.
This way you keep your Arc locked, nothing good comes from unlocking the bootloader yet.

That's not entirely true. You've got custom ROMs being developed; over-clock kernel just released, Recovery and what not.
Unlocking the bootloader is personal choice. I may not unlock my bootloader just yet but I can't deny that with improvements being shown, it's an increasingly tempting option. LOL!

[Q] Arc Root

Well It looks as if I Cant remove unnecessary apps on my Arc without rooting.
But here is something i wanted to ask before I go ahead with doing That
Q1) Is it necessary to Unlock My Boot Loader for Rooting or Rooting can occur without Unlocking it aswell?
I mean that I have read rooting without unlocking it but will it be the same locked or unlocked?
Q2)Unlocking My Boot loader means a 100% surety that my warranty will be Nulled right? (I Live in India, Rules don't differ here or in UK does it?)
Q3) If I have Rooted and NOT Unlocked my Boot Loader, Can I still update my Phone software through SE PC Companion? And Is my Warranty Still Safe?
Because I read that ICS will be available for Arc in the first quarter next year so I want to update my phone using SE PCC and NOT by flashing even though I know the pro's of flashing
Thank You so Much!

1. No you dont have to unlock BL to root your arc search for doomlords easy rooting toolkit
2. As far as I know yes
3. Yes you can still update with SE PC companion but I think updating via PC companion removes root. And your waranty is safe

You can use zegrush to root without unlocking bootloader. I live in India too. U can still update after rooting but not after unlocking. Rules apply everywhere.
Xperia Arc (rooted)

Thank you sooooo Much!!!
One more question
@Tatit1011- in reply to ur question 1, are dere any pros/cons of rooting after unlocking BL and. Rooting without unlocking it??

If you unlock your bootloader you CAN: flash custom roms, kernels(for overclock), and generally anything.
You CAN'T: upgrade via se, either pc or ota via the phone. Plus drm is lost, as is your warranty, but you can re-lock it
Generally, if all you want to do is remove system apps and use apps like titanium backup, root explorer etc then just root. If you want to try custom roms(there's only one you can flash over stock kernel, I think) then unlock the bootloader.

Rooting

OK, I updated My Arc to a .62 Latest Firmware via SE PC Companion.
Can you tell me how to root it now?
There are options available right?
I have a Locked Boot Loader and Dont wanna unlock it.
Thanks Alot!

it aint possible without an unlock. Get a pro to unlock it for you. Costs about 15 quid warranty and drm remains intact.

Downgrade to .42 or .58 firmware with Flashtool and root it using the zergRush exploit.

@somedude67 - My DRM can be saved even after unlocking my bootloader??
How??
Any free way?

No, there's no free way, contact e.g Jinx13.

Hello, I'm new here, with a new xperia arc.
I have .42 firmware and I want to root, but i have a question about it.
My phone is stock, locked bootloader, untouched...plain stock; If I root with doomlord rootkit I void warranty or it's safe?
I've seen that it is a un-rooting kit there, but it works well in case i want to unroot?
And if I root now, and update via pc companion the future ICS 4.0, it will be ok with the phone and all right?
I just want to root but not to void my warranty, or unlock the bootloader, or to flash another firmware or system.
Thanks in advanced

It won't void the warranty - but not 100% sure as I don't really about warranty
And yes, you can update to 4.0 later

Thanks, I still have 2 years of warranty and i just want to be safe

So, can someone confirms that this tool Xperia 2011 Easy Rooting Toolkit [v4.0](zergRush Exploit)( http://forum.xda-developers.com/showthread.php?t=1320350 ) don't unlock the bootloader and don't change the phone except giving root privileges? As I said, I want this for the warranty and stability of the phone
(had bad experiences with my former LG GW620 phone last year :-<)
Thank you again

Upgrading from .42 to .62

I have a UK Xperia Play on .42 firmware with CWM recovery and root provided by Zerg Rush.
I've heard that I need .62 to install some of the custom firmwares.
.42 appears to be the latest firmware I can get OTA. I'm not sure the best way to upgrade to .62, do I need to go via .58 or similar.
Does it matter that I have a UK phone?
Is it possible to preserve my settings?
Will I need to re-root at any time?
In the long run I am looking to install DooMKerneL and probably something like Jokawild.

You have to flash the ftf file for your phone
Here is a link to 99% of them
http://forum.xda-developers.com/showthread.php?t=1589399

If you install a new firmwares. Maybe you'll need to root it again..
But since the devs makes the pre-rooted custom ROMs, you don't need to root it anymore

I don't have an unlocked bootloader. Is this required to install a custom ROM even if I have root?
Is there any disadvantage to unlocking the bootloader?

No unlocked bootloader = no custom kernels/ very limited to roms
Only disadvantage is it voids your warranty, but being that you have root, you have no warranty anyway lol

I was in the same position as you. I wanted to get a custom ROM and be able to overclock my phone. After a few annoying errors, I finally got it up and running
Basically, your going to have get your phone into flashmode and then flash the .62.ftf file on your phone. Congratualtions you now have .62FW (although youve lost root).
To get root on .62 FW, your going to have to flash a custom kernel (I did DoomKernel v14). To flash a kernel, your going to have to unlock your bootloader. After unlocking and flashing the kernal, your phone is now rooted.
And plus the positive side Ive heard is that you CANNOT brick your sony eircsson phone. (well you probably could but there is a very very slim chance of that happening).

Thanks.
It seems I can't unlock via the regular Sony way as Unlock Bootloader is set to no.
I think I need S1Tool or something similar (maybe something I have to pay for) to get my bootloader unlocked. I'll check the forums a bit before I ask any questions that haven't been asked before

i did it via omnius and it work great, i just payed 19.76 for one single unlock credit on gsmserver

not sure why people say that root voids warranty.
i have ATT play 4g and it was having hardware issues, so i flashed the stock ATT software back and took it to the store. i got a "new" one in the mail two days ago.

I also sent my rooted xperia play that had the slider broken to CLARO El Salvador and they repaired it (They flashed their ROM again XD)
Now i have unlocked bootloader but who cares i have premium insurance

Any modification to the software voids the warranty..

Update:
I downloaded s1tool and connected the test point to the ground. Everything seems to have worked so I am guessing my bootloader is unlocked. Is there anyway I can verify this, or should I just attempt to install a kernel?

Try to put the phone in flash mode (green light) if it recognizes it, it's unlocked. I think there is a sequence or symbols/numbers you can do to check it, but idk what that is since im a r800x

To check your unlocked bootloader you need to dial: *#*#7378423#*#* , then go under, Service info > Configuration > Bootloader unlock allowed: Yes/No.

[Q] Can I root without unlock the bootloader or to locked it again?

Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!

well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK

Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!

without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime

I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks

You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.
