[Q] Root on unlocked bootloader

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!

[Q] Bricked Bootloader XT910

Hello, guys!
I could not found another thread about my specific problem here.
So, I'm sorry if there's one already...
I have installed CyanogenMod 10.1 (JB 4.2.2) Nightly on my XT910.
All good.
When I installed back "BootMenu Manager", it said that my bootloader was not hijacked.
So, I do hijacked the bootloader and rebooted the phone.
And here my problem begins.
My bootloader is bricked!!
I could not found a way to hijack it again.
It is booting directly to Fastboot and waiting for a valid flash.
I was looking for some custom ClockWorkMod img recovery files, but I'm not lucky at all.
Please, is there a way to unbrick my phone?
Thank you very much
You can always flash fastboot files to get back to stock which you can find in the dev section ( flash with rsd lite )
But be sure to flash correct fastboot!! If you were on ics flash ics fastboot, if you were on jb flash jb fastboot
Do you know which system version you had previous to flashing 4.2.2 ?

Hi!!
My previous version was 4.0.4.
The version 4.2.2 worked perfectly before I try to manualy update BMM 0.2.7 to 0.3.4.
A friend recomended me to try the oficial rom from Motorola (version 4.1.2).
It replaces the bootloader, the kernel and the system itself.
Now it's working perfectly, but I lost root =(
Anyway, thank you very much for the help!!!
I'll be carefull next time

Help needed

Hi I have just recently got a xperia z tab WiFi/4g 16gig model. It has been upgraded to kk 4.4.4 .292
as I understand I can't root this directly, with trowel or easy root tools, what i need to do is downgrade kernel via flashtools then root, then flash recovery then update kernel back via flashtools.
My problem comes when I can't find valid links for this particular model.
Can you please help me, also correct any mistakes that I might have made in my understanding.
I am not a newbie in flashing etc, please help. T I A

Flashing Sony Xperia z2 D6503 with CWM Recovery installed unsuccessful

Good day,
I have this Sony Xperia Z2 D6503 currently on Android 4.4.4 using 23.0.1.A.0.167 mobile phone which I am having trouble flashing, I have unlocked the boot-loader. I have flashed a custom Rom on this phone before, using suggestions that I have read on the Xda-Developers site. I reverted back to stock Rom after a while, because the custom Rom I flashed had issues with network service signal, and it began to restart the phone on it's own. I have found a good Rom and I am trying to flash this but it doesn't work. I followed all the steps like what I did in the first successful flash. I downgraded the stock Rom, rooted the stock Rom, installed CWM recovery, the exact same way as the first. Also I ensured that the MD5 number is a match and the Rom still won't flash, even tried TWRP recovery. It kept showing bad file. Is it possible that my boot-loader got re-locked when I reverted back to stock Rom using flash-tool. And how can I resolve this problem so that I can go back to flashing successfully.

Having some difficulty in doing this. Have tried a number of options and I keep getting the CWM recovery. Was trying this one
twrp-2.8.7.0-sirius .img using the command window option. with no luck and the one click method, what am I doing wrong?

If you unlocked you bootloader those steps are a waiste of time. Just flash a kernel with recovery.

Unlikely, if your bootloader is relocked it should still let you flash the file but won't boot.

Thanks for all the help. I was able to finally flash the ROM. I just started all over from scratch, flashed ftf .167 with Sony flash-tool. Then rooted. Installed CWM recovery. Tried to flash kernel with recovery, that didn't work. So I just tried flashing ROM directly without wiping anything and it went thru. was very surprised. By the way it was eXistenZ Ultimate | 4.5.0 ROM.
Thanks developers at XDA:angel::good:
