(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

[Q] Help rooting android 2.3.3 Xperia Play r800at

Hello, I am new to these forums but have looked through (to the best of my ability) and have not found the solution to my problem. That problem is that I want to root my AT&T Sony Ericsson Xperia Play r800at (android v. 2.3.3).
I had it previously rooted using the Zergrush method (was still on 2.3.3) and it worked just fine, then about a month ago (perhaps half a month) my phone automatically updated itself via the software update function. Now I cannot get root back using the Zergrush method. I also tried the SuperOneclick method to which it hangs on step #7 and I am at a loss.
What information do you need about my phone to help in figuring out any possible solution?
Thank you for your assistance and I look forward to any replies.

Have you tried with DooMLoRD's Easy Rooting Toolkit?
PD: If the phone updated after November 2011 it seems you can't use zergRush, try with Flashtool

Indeed I have, that was the Zergrush method I mentioned previously. Thanks for asking.

I'm new with this but I think that your only solution is unlocking the bootloader and flashing a custom kernel & rom

If I were to use Flashtool, what kernel would I need and do I absolutely need to unlock the bootloader in order to flash said kernel? Also, is there way to relock the bootloader (with original files intact) just in case I need to return the phone to AT&T repairs/maintenance or anything?

Ok, I've searched a bit more, seems thath you DON'T need to unlock your bootloader, just need to flash a firmware build that can be exploited by zergRush method.
I've searched and I found this (I haven't tried it)
1. Download flashtools
2. Download the .270 build Xperia_Play_3.0.1.B.0.270_ATT.rar
3. Flash the older build
4. Use flashtools to root
And you should get root acces

Oooohhh... My eyes flashed at that one!! I will try and get back to you as soon as possible!
Fingers crossed!

Good luck!
When you finish (sucessfuly I hope), if you want to unroot just update the phone with PC Companion

Yep that will work. Once rooted you can update to the latest AT&T build which is .285 but you must do it OTA. If you update through your computer it will remove the root.

He was talking about the carrier branded rom from AT&T which is his cellular provider. OTA means over the air. Basically doing the whole update process through the phone.

Thank you =)

Dude, it totally worked!! Not a single hiccup anywhere whatsoever!!! Thank you so much!!! :highfive:
Since you were talking about OTA updating and such: If I were to root and then update to the latest build OTA is it still possible to unroot using the flashtool or whatever was used to gain root? The reason I ask this is should AT&T ever need to look at my phone...

I think that the answer is yes, just update the phone with pc companion, also you can flash again .270 firmware and the phone should get unrooted

Awesome, and is there anything else I should be aware of? After all I am flashing things *wink wink*

As far i know, if you want to try any room, make sure that is compatible for locked bootloaders (you phone have a locked bootloader) and for you mobile phone type , follow the instructions carefuly and if you don't understand something, ask Oh, and don't try to flash a custom kernel (like DoomKernel) with a locked bootloader beacause you will brick your phone.
That's all I can tell you

if you downgrade will you lose your files?

thanks Mercado for the mirror sight for SOC 2.3.3

YOU DON'T HAVE TO UNLOCK BOOTLOADER TO ROOT.
Download flashtools. Install on computer
Download ftf from general stickies( select. .42/.54) only these can be rooted
Drag and drop ftf into flashtools main screen
Put phone into flash mode(hold back key while plugging into usb port) flashtools will install Rom
Restart phone.
from settings select usb debugging( development) and unknown sources( security)
Download from doomlords thread for rooting gb file
Keep phone switched. On and connected to computer run the script and follow on screen prompts.
When done phone should be rooted.
IF BOOTLOADER IS LOCKED YOU CAN UPDATE OVER THE AIR.
ONLY DO THIS if 100% SURE BOOTLOADER IS LOCKED this will update to 2.3.4 build. 69 latest stock from Sony.

Why not unlock bootloader, flash custom kernel with root support, root and delete bloatware (or what you now are going to do) then flash stock kernel, relock bootloader and voila - everything fixed?

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?

Towel root. Rooting won't erase anything from your phone

Towel works great but not if you've already upgraded to 4.4.4.

Is your bootloaded locked, or unlocked? For LOCKED bootloader, I used the following procedure multiple times with no problems (I don't see why it wouldn't work for unlocked bootloader, but I haven't tried it):
1. Flash .230 kernel using FlashTool (basically, you are temporarily downgrading your kernel).
2. Root your phone using newroot.
3. Flash either .283 or .292 kernel (whichever 4.4.4 build you are on) using FlashTool.
4. (optional) Flash a custom recovery (I use XZDualRecovery by [NUT]
You will need kernels to flash in steps #1 and #3 - either search for FTF files to download, or create FTFs yourself using XperiFirm checker/downloaded and FlashTool. The procedure for creating FTF is described in XperiFirm thread.
There may be other ways; I am only telling you what I tried myself, and know 100% that it works...

The way I understand it, the method I described should also work for unlocked BL.
Of course, you don't need to flash a new ROM -- just a kernel. That's exactly what I said... First, downgrade your existing kernel for rooting, and then, after the rooting is done, flash the proper kernel back.

I wanna root my phone , with locked bl. May I know which website to follow??
