[Q] Unlock, Root and Relock - Xperia Arc Q&A, Help & Troubleshooting

Im going to testpoint my phone tomorrow. If i unlock, then apply root. Will this cause any problems for relocking the bootloader ??
EDIT: readed a litle more, need recovery to root .62. Will this cause any issue for the relock process with se1tool ?

Nope rooting will not affect locking bootloader or unlocking bootloader.
But with unlocked bootloader you can apply various roms etc.
If you stay with unlocked bootloader DO NOT UPDATE OVER THE AIR OR YOU WILL BRICK YOUR PHONE

I know the brick issue. Thanks for the help.
Any guide for applying root on .62 with unlicked bootloader ??
From my sexy LT15i

I'm trying right now the locked bootloader method but I'm a 0% battery bugged Arc user so I first have to inject the battery patch in the firmware. AFAIK you can get to .62 only by OTA updating from .42(keeping root status)... or by PC Companion(losing root status)... but I'm facing some problems(rooted .42, applied patch with doom's modified zergrush rooting mthod): when I want to search for updates OTA(I relocked my bootlaoder) I download the update but when it's installing, it reboots 3 times(after every step) but at step 3 it reboots and says Software update could not isntall. Try Again or something like that.
Later Edit: Check the general section, you have the ICS ftf there and tutorial to root it

No, i dont want to upgrade to ics yet, only testpoint, root .62 and relock

Wait for OTA
or, flash through recovery (if your bootloader is unlocked) +autoroot

i have 2.3.3 rooted bootloader locked and a ota update aviable i hears if i so a ota update i ll lose root :/
what did you say?
anyway, if you followed the downgrade-root-OTA method, you won't lose root for as long as all your succeeding updates will be AND ONLY BE via OTA granting your bootloader is LOCKED (as your phone will be bricked if BL is unlocked) and that the system files were not tampered in any way..
.. For the INSTANT solution:
Go ahead and unlock your bootloader and flash Doomlords kernel.
Done and done.

You can have root without unlocked bootloader
but It makes me wonder why you would revert back to locked?
just wait for someone to make a ROM / nandroid and flash the new file lol.
OTA is for people who aren't used to fooling with there device
apparently i tried rooting but i cant root without unlocking bootloader, only after i unlocked the bootloader i manage to get root
so it is advisable to just keep my unlock bootloader and flash new roms using Flashtool?

If you want a practically guaranteed method of rooting, yes that would be easiest. FTFs only come out like 1-2 weeks at most after the update is sent out anyway

[Q] Does OTA update removes ROOT

Hi guys, didnt follow the forum for a while due to big problem with PC, so i need simple and clear answer to my question.
I have now baseband .56, firmware .42
Would OTA update to .62 remove ROOT or ROOT will be remain and functional.
My girl update shes xperia neo, and root remain and it is quitly functional, but dosent know how arc respond to this.
Also if ROOT is removed, how can i root it on .62
Thx
Root will remain if you upgrade OTA.
remember don't ever update ota if you unlocked the bootloader

It aint a big deal...nothing would happen! More or less you won't be able to update! Relocking the boot loader would do the thing! But if you removed some bloatware then you might consider flashing the same firmware you are using again, wiping everything and then rooting it again! And then doing the OTA update!
Making an nandroid backup before reflashing the firmware is required so that you can restore your apps and settings! Many people ran into the problem where ota update wont work even with locked boot loader and they pin pointed removing some system apps or bloatware for it! Well in that case i already suggested you!

ii.Connect the phone with usb debbuging enabled.
iii.Then press the lock icon on flashtool.

(Q)bootloader and rooting

hi to every one i would like to ask before i unlock my bootloader and rooting stuff. im presently on stock rom right now with firmware 2.3.4 baseband ver. -64 and build number .62. i alredy browse threads and guides about this but unfortunately i was not able to find answer.
ok my question is this.
1. will it be possible for me to install custom rom if im just going to unlock my bootloader but not rooted?
2. there are topics about easy rooting on gen. discussion .i just like to ask,is it possible to disregard downgrading process from .62 to .42 if the bootloader is unlocked for the rooting process. since i dont want to downgrade.there has been issues of bricking the phone if your going to downgrade and update afterwards via ota.
3. can anyone give me updated guide for unlocking bootloader and rooting based on my current firmware.
Thanks in advance.

Yes, custom roms are usually (always?) prerooted, so it gives u root permissions. Bootloader is needed to flash custom kernel.

If the bootloader is unlocked ur phone gets bricked after update. However u can downgrade with locked bootloader, next root and than update. If u want lock bootloader use file attached (unpack rar archive and flash ftf using flashtool).
On the other hand u can install CWM and use RootXperia.zip (attached) to root.

Bootloader:
Unlocking
Root:
1. 2.3.3 - use SuperOneClick Method (maybe work with 2.3.4 i dont use it) or RootXperia.zip or custom Kernel/Rom
2. 2.3.4 - use RootXperia.zip or Custom Kernel/Rom

Root Xperia S (6.1.A.2.55)

Hello,
I'm one of those lucky guys who got the 2.55 build number.
Wandered around the forum for some time, seeking for a way to root my phone, but don't want to risk before being 99% sure that this may work.
As I understood, Bin4ry's method won't work with my phone, which results in need of unlocking the bootloader.
I checked its status and it shows that its Unlockable = Yes.
Now, let's say I unlock the bootloader, what should I do next? Flash a prerooted ROM?
All I could've found on forums was "UNLOCK YOUR BOOTLOADER" and "BIN4RY'S METHOD" stuff. Maybe because people were posting about this 2.55 thing alot. Maybe not.
All I need is a n00b friendly tutorial.
Btw, I'm on 4.0.4 ICS, which is pretty obvious.
Thank you, in advance.

Unlock your bootloader and just flash an auto rooting kernel.
But if you're unlocking the bootloader you may as well flash a Jellybean rom anyway
Sent from my Jellybean Xperia S
Hi, I hope the OP doesn't mind, but I'm kinda in the same situation and I need some help from you guys, because I am currently a Samsung owner (please don't throw rocks ) and I don't really know much about flashing ROM's on Sony.
So... I have with me my brother-in-law's Xperia S with 6.1.A.0.453 (ICS 4.0.4), never been tampered with, just bought, updated to ICS and rooted with Bin4ry's method.
All great, but I was hoping to flash 6.1.A.2.55, because I heard it is the latest.
But now the hard part comes, the phone has Locked Bootloader and I can't unlock it because "Service info > Configuration > Rooting Status > Bootloader unlock allowed" says NO.
That being said, if I flash the .55, how do I root it?
I updated and rooted an Xperia U a while back, using a method of changing the kernels, something like this:
Flashing the ROM I want (the one that can't be rooted)
Flashing an older kernel from a stock Rom witch was rootable
Root it
Flash the kernel of the last ROM, and root remains.
Do you guys thing that this method will work on Xperia S?
Flashing .55
Flashing an old kernel (from 6.1.A.2.45 or other that can be rooted)
Root it
Flashing the kernel of .55 again, and hoping that the Root remains.
Also, where could I find those kernels?
