[Q] Root on unlocked bootloader - Sony Xperia P, U, Sola, Go

Hi!
I am new to rooting and flashing on Android. I have an Xperia S which is currently in repair for yellow tint/spots on the screen. When I get it back and know that it is working i will unlock the bootloader using the official method.
My goal is to have rooted gingerbread on the phone, maybe with a better kernel. I have found a prerooted ftf with the FW that I want. Can I just flash that one and it will work?
Do I have to install custom recovery?
Thanks in advance!

Have I understood it right? unlocked bootloader + flash prerooted system rom. That should work?
If I want to install custom rom I need custom recovery. I would appreciate if someone could verify this for me, thanks!

do I lose warranty if I install a custom recovery + root with z4root + flash a custom rom on Optimus One?
thanks
Yes.
But you still can try flash back the official ROM before you send it back.
If no success then goodbye warranty (If they see it ofcourse).
Cheers
so there are no bootloader unlock to do?
[for example, I did bootloader unlock on my Nexus One (my phone... Optimus One is my girlfriend's phone)]
no news...?

I did another question mate...
so, can sombody confirm that the procedure to install a custom rom is the following:
- install a custom recovery
- root with z4
- install a custom rom
anything else to do? (no unlock procedure as for nexusOne?)
Second question:
wich is the procedure to flash back original recovery and original rom in case i flash something custom (recovery or rom or both)?
thanks mates
No, its all what you need for Custom ROM. Maybe - for unroot you need FW V10a(b,c) not higher.

[Q] How to update when bootloader is unlocked Lww

I have WT19i and i have unlocked the bootloader official method. Now i flashed .58 firmware and now i wanna update to .62 but i have read somewhere that after unlocking bootloader if u update the phone gets brick.
So any solution?
If i flash .62 firmware directly then would i get root access too?
cause i have root access in .58

If you have stock kernel, just relock the bootloader. Making update directly from phone with unlocked bootloader causes brick indeed.
First relock the bootloader, then make update directly from the phone(3G or WiFi) to .62.
Relocking is written in my tutorial, check there if you need help how to do it.
If I relock bootloader, the process perform a wipe same as when I unlock via Sony Official Method ?
I want relock my bootloader, but with no wipe =D
(using stock kernel and stock .58FW)
Dont forget that wipe is best thing what you can do before upgrade to ics
Sent from my ST15i using XDA
I have Rage Kernel installed, so now what to do?
Or shall i flash a custom rom?
and one more thing, if i install custom rom then would i be able to upgrade to ics easily?

Your question is already answered, on the ICS stuff. Reload original firmware just to be sure prior update, always perform clean wipe when shifting ROMS so as to avoid un-pleasant experience and make most of it.

[Q][SOLA]-Some questions about flashing stock ICS .54 from eXperience v.1.1 by Divaks

Hi guys, i've unlocked my bootloader and i've rooted. I flashed eXperience v.1.1 by Divaksh (stock based) and i want to return to stock ics 'cause i want to try cm9.1. Now the questions:
1- Will i have locked bootloader again?
2- Will i lost my root permission?
and the last: can i flash stock ics via CWM?
thank you :good:
Nope. Bootloader is independent of roms & kernels so you wont lose Bootloader unlock
But you'll always lose root if you flash Stock. And if you want to flash with cwm, see if anyone has uploaded a CWM flashable zip for the firmware. Else you need to use Flashtool
Hope it helps
Cheers

So this: http://forum.xda-developers.com/showthread.php?t=2030261 would work just wiping and flashing with CWM?
Thanks for your help :fingers-crossed:
Yes I believe that ought to work fine
Enjoy
Cheers
Thanks man but the stock ics flashed by CWM and pc companion said me i had to update the system even if it was already .54 version and any attempt to update failed because of my unlocked bootloader. The same firmware flashed by flashtool didn't need any update and finally allowed my to boot "pure blood" ROM. Thanks anyway :cyclops:

[Xperia U] Go back to Stock from CM9

So, I have my unlocked bootloader and CM9, I want to go back to the stock firmware and use a custom kernel, so.. for install the stock firmware, can I just flash the ftf via flashtools normally? or I will have any problem?
and for install the custom kernel I suppose that i only should install a recovery and flash it.... Am I right?
Thanks!

Yup that's about it.
And you flash custom kernel with fastboot, that will save you tha hassle of rooting and installing CWM recovery..

Can we use this method in xperia sola too? So we flash the stock firmware directly by using flashtool and then the kernel, and in any part of the process do we need to wipe anything at all?
Thanks in advance

RootKit Questions

Hello
I have a few questions about the hole "thing" cause this is my first android phone and on apple there was just the option jailbreaked or not jailbreaked
My first question is about the bootloader.
since i was reading the thread "[FULL ROOT] Community RootKit! (ASEC vulnerability) {v01} [20140615]" i am asking me why should i unlock my bootloader when im able to get root without doing this?
Is there any special point for wich i need the unlocked bootloader or is it just written for the people who unlocked there bootloader already?
Then to second question is about the sequence.
Am i right when i
1. get root
2. install cwm or twrp
3. install custom rom?
by the way: is there any huge difference between twrp and cwm? because at the table "Kernels" there is the TWRP for the Xperia T2 Ultra and an unofficial version and from CMW is an unofficial version too? Wich should i use?
and my last question is should i wait for version 2 of the RootKit or are there just small differences?

Bootloader unlock is required to install Custom kernels like DOOMLORDS kernel. In case if you dont want that then no need to unlock BL.
Just follow this post http://forum.xda-developers.com/showthread.php?t=2784757 to get root on Locked Bl and then revert back to .402

A custom ROM is different from a custom kernel. Some custom ROMs do not require custom kernels (because they use stock kernel), but others do. So it really depends on the custom ROM that you want to use. Instructions and requirements will be posted in the respective ROM thread.
But if you want to use a custom kernel, then you will need to unlock the bootloader first.
And obviously, if you want to flash a custom ROM that needs custom kernel, then you will have to unlock your bootloader first.
Even if you want to flash a custom ROM that does not require a custom kernel, you need to first root the phone with the RootKit. Because flashing custom ROMs is usually done via recovery, and recovery installation requires root.
Hope the above is not too confusing.

Thank you
So just to be sure.
I Run the toolkit for root
Then i take twrp or cwm
And then i flash a custom Rom wich use stock kernel
And that can i do with a locked bootloader?
What can be different in an other kernel?

Yes, run Rootkit, install recovery (TWRP/CWM) and then you can flash custom ROM which uses stock kernel.
Custom kernels allow functions such as overclocking, undervolting, etc.

Take note that by modifying your device you warrenty is voided and you can posibly brick your device
(brick meaning dead phone) aka brick

Or you can use the toolkit on .55/.69
Then follow Nuts thread and http://forum.xda-developers.com/showthread.php?t=2784757
this would bring you back to .402 and have recovery installed by default on Locked bootloader

then i have 2 new questions
1. How can i downgrade my phone ? just download the fw and use flashtool?
got an iphone till now and there it was a hard work to do it ..
2. is there any difference between locked and uinlocked bootloader? i mean in the point of restoring so that i have my warranty back?
1. There's now an even easier way to root the 402 firmware that does not require you to downgrade first:
http://forum.xda-developers.com/showthread.php?t=2784900
But note this post, where you have to change something in the install.bat file for it to work on the Z2:
http://forum.xda-developers.com/showpost.php?p=53480221&postcount=81
2. It's a little more work if your bootloader is unlocked and you want to relock it before sending it to the service centre. You need to have your TA backup before doing so. If your bootloader is locked, you just have to remove root via SuperSU before sending it in for service.
