Hi, I have a Tipo s21i.
Looking to flash a custom rom and possibly root. Although looking through a few guides it says I need to unlock bootloader. But when I go on service menu suggested on sony website it says my bootloader is not unlockable.
Do I need to unlock the bootloader to install custom roms?
If so what can I do to do it as it says its not unlockable?
Thanks
First check if your bootloader can be unlocked. Open Phone and dial *#*#7378423#*#*
Service Menu should appear, go to service info, Customization Settings, at the end if Rooting Status: Bootloader unlock allow No you can't unlock bootloader. If it's missing you can't unlock it. If it is said Yes you can. You can use Flashtool or official Sony way to unlock it. Search XDA there are plenty tutorials on how to.
Good Luck!

And how i can do this if my bootloader unlock allowed show no???
:/
No. You can only use roms for locked bootloader only.

If your unlock status is no then for now there is no solution available to unlock it.
You will have to stick to locked bootloader roms.

1.First u need to unlock bootloader
Check bootloader status,dial from your phone to check status :
*#*#7378423#*#*
service info --> configuration.If its allowed,go to sony official site and do the unlock bootloader procedure.
2. After unlocking bootloader u must root ur phone.Do the update stock sw version to 11.0.A.5.8.After that go to unlockroot.com and dwn app.Usb debugging enable and start app.EDIT:after rooting google clockworkmode recovery and flash it via cmd
3. Find and download MIUi rom,flash boot.img with cmd.Transfer rom zip file and flash it via CWM.
4. Wait after that set up ur phone and enjoy
Hi.. I have Sony Xperia (ST21I) with build number 11.0.A.4.27 (android version 4.0.4). Few months before it rooted this phone with a unlock flash tool. I am sure that the phone is rooted now. And i managed to install a Clockwork Mod too with CWM installer.apk file. And tried too boot into clockwork mod. It worked. Now I don't know which bootloader I am having? A locked bootloader or a unlocked bootloader. This question may look silly to people who are really fluent to android. I never carried any process to specifically unlock my bootloader. I am asking this question because I have read that "You can't root your phone without unlocking bootloader". If what i read is true does that mean i am having a unlocked bootloader?? So now is it possible to flash a custom rom for unlocked bootloader? Thanks in advance.
only few roms

Dial *#*#7378423#*#*
You probably have a locked boot loader as bootloader can only be unlocked by a specific key.
I too have a xperia tipo and it can be rooted without unlocking the bootloader. I used unlockroot to root it.
Thanks Guys!!

Im trying to unlock bootloader and got error!
Im on 18.3.C.0.37 4.4.2 firmware
FAILED (remote: Command did not succeed)
finished. total time: 0.102s
Where is problem?
Have you checked to see if it is unlockable. It does say bootloader unlock allowed: yes, in the service menu because if it says bootloader unlock allowed: no then it can't be unlocked ever. I think I'm right in saying that sim free handsets are usually unlockable and carrier/network locked devices are usually locked down. My m2 is unlocked to use any network and mine bootloader is unlockable.

Hmm... I don't know, because I lost my TA Partition when unlocked bootloader :silly: But I think that's not a problem, just try again.
I tried but still the same error
And if I do enter command again its says. "remote: Device already rooted"
But service menu says "Bootloader unlock allowed: YES"
And I just tried to flash kernel via Rashr and it worked I think. I flashed stock kernel over stock (Created backup Stock and flashed Stock kernel)
One thing would be like service menu tells wrong info...
Im looking info from peole who has advenced knowledge or faced same problem

Try with Flashtool, they use Sony's official unlock code, and it will tell you if you have unlocked bootloader or not.
Xperia M2 D2303 on K.K. 4.4.4
It still not work i tried another pc but still says "remote:command did not succeed"
Drivers connot be a problem. I think something is wrong with my TA or Cusomization...
Try if PC Companion can fix it, if it's something messed up it will tell you that your phone is modified. Yesterday i unlocked Xperia E with Flashtool. It was 5 minutes job. You doing something wrong, but you'll get it.
Xperia M2 D2303 on K.K. 4.4.4
Not sure if this is the case, but I've read you can't re-lock the bootloader if you have a custom kernel (or ROM) installed. Or better, you should be able to, but then the phone won't boot.
I would try flashing the whole stock ROM and then try to lock it again. At least as a test.
But if PCC says im modified how can i fit it then
Hi everyone,
I'm a beginner in this area. I want to install the Lollipop makeover ROM on my Xperia E3 D2203. For what I have read in some threads, to flash a ROM I need to have my phone rooted and then I have to unlock my bootloader... I don't know if it's possible to unlock my bootloader because when I dial *#*#7378423#*#* Service Info > Configuration, it says "Bootloader unlock allowed: No".
Can I still unlock my bootloader? Or is it another way to flash the ROM without unlocking bootloader?
Please HELP!!!!!!!
u can root and use xposed for u need. About custom rom, forget ,on "bootloader unlock=no" ,no recovery,no custom rom. For root read this,http://forum.xda-developers.com/xperia-e3/general/root-xperia-e3-d2203-locked-bl-t3075559. good luck!
For custom rom unlock booloader first

So there is no way for me to get a custom rom?
When I got my phone, the unlocking status was unlock allowed: yes
I unlocked the bootloader and installed a custom rom from androplus that had supersu.
after the rom was installed the unlocking status is unlock allowed: no
now I have a nagging notification to update android on my phone and it can't because I'm running a custom rom, and I can't update the rom because the bootloader is locked. what do I do?

So, basically you unlocked your bootloader to flash a custom rom and now you want to receive official ota updates from Sony?
If so, you have to stay in stock roms (flash with flashtool in flashmode or Xperia Compation in repair option) otherwise you need to wait for developer of custom rom you installed for an update.

no not quite, as I said I want to update the custom rom, but I can't flash another rom because my bootloader has been locked and I can't unlock it again.
the escape plan would be to flash stock rom back onto it, but I'd like to keep supersu if possible.

no, the site that provides the guide and key to unlock the bootloader specifically says I can't unlock it if the status says unlocked allowed: no
are you saying I should try anyway? other forums says there is no way around it if unlocked allowed is no.
the reason I haven't tried is the threat of having my data wiped without actually unlocking it

lock and unlock your bootloader as many times as u want by FLASHTOOL. just keep the key with you
