You can only flash stock based ROMs with a locked bootloader.
If you wanted to flash custom ROMs or kernels, you needed to buy a SIM Free, carrier free phone.
There is no way to unlock your bootloader.

thanks for the reply, i dont mind a stock based rom but i cant even get root

You can easily get root without an unlocked bootloader.

[Q] Xperia Mini Pro Questions

Hello
Just purchased a SK17i Xperia Mini Pro Black Version that is locked to 02 (UK network). I am obvously new to all this stuff but do have a basic understanding but here are some questions:
1) I am thinking of waiting until Android 4.0 is Officially released by SE to update my phone (btw, anyone know when the update is coming). Was wondering when I update will I still be able to root my phone?
2) When I root (if I can) I want to install Set CPU to overclock my phone. However I have heard this drains batteries? Is this true and if so how can I make my phone faster?
3) I need to unlock my phone. Can this be done for free after rooting? If not, can someone link me to the cheapest place I can get this unlocked from?
Thanks in advance to anyone that answers
Hey dude,welcome to XMP family.
1)According to Xperia Blog,XMP will get the ICS update in the end of May or early June,after the first wave for arcS,neoV and ray.I don't know whether we can root it on official ICS or not,but I think to get a rooted phone is easy once you unlock the bootloader,and besides,there are so many developers here.
2)When it comes to overclocking,apparently it would cause battery drain faster.But with my experience,I hardly feel its difference on SE stock Rom.As for custom rom like FXP's,which I has used for a while,it drains about 2~3% per hour while idle(drop speed is two times than stock.)
3)Certainly you can unlock your phone for free,see this thread & tutorial.But it should be noticed that once you unlock it then you may invalidate your warranty.
Mine is on FXP CM9(ICS) and it's kind of laggy,but I can't tell it's because of the ICS rom or existed bugs.As SE said,we may not have the same experience like Gingerbread if we update to ICS.

Hello mate, thanks for the great post
I think I will leave stock ROM once updated actually, seems to be running fine atm as it is.
I think I will still update to the official ICS when it comes out as does look worth it.
Just about no. 3) I think your talking about after rooting, the process to get custom ROMs by unlocking the bootloader? I was talking about the network? lol
Unless I'm mistaken?
Thanks again

There is no way to get your phone unlocked from a network for free but WontanServer offers an unlocking for $15. You can try that out. Just type WontanServer in Google and click the 1st link. WontanServer is legit and won't steal your money
Though as a warning you might not be able to update to ICS as it also might unlock your bootloader. Just double check, as I am not 100% sure. Also it will void your warranty

Thanks alot, will take a look at that website
What do you mean by updating to ICS will unlock my bootloader? Isn't that a good thing? Don't mind about warranty, can have that sorted out but don't understand the bold line mate
Thanks
good thing in the sense? If you don't bother about warranty then you can try custom ROM ics.but the problem is some bugs are not fixed by developers they will take time.main bug is camera not working..i am using ics so just check k? Good luck

He meant that the Wotanserver network-unlock method might unlock your bootloader (which it does). This bootloader unlock, whilst giving you access to custom ROMs etc, might not behave with official SONY updates (such as ICS) - I'd link you for proof but I'm not allowed to due to my low post count .
Also, Google 'Omnius Unlock'. They will unlock your phone for free over the next few days (Easter promotion). I'm not sure how reputable those guys are though so you'll want to check.
Thanks for that Omnius Lock thing, looks great and will check it out
So, if I unlock it I may be unable to upgrade to 4.0? That is a bit stupid to say the least? Anyone on an Xperia that was unlocked then ugraded to 4.0? Did it become locked again?

If your phone's bootloader is unlocked you can not recieve any official update through Sony as it will brick your phone but you can install a ICS ROM.

Well I'm not sure about 'stupid', you'll have to weigh it up. If you look in the development section, there's already a very useable version of ICS (look for MiniCMSanwich), which is potentially better than Sony's bloatware-infused and themed version (not to mention probably unrootable) due in a couple of months.
I think it's mainly FOTA bricks that happen (over-the air updating from Sony), and some bootloader unlocks allow for this by just patching the bootloader to make it seem unlocked (any SETool unlock will do this). So there are a number of options.
Be careful also of some bootloader methods stripping the DRM keys, these are used by Sony services like TrackID, which will cease to work (permanently) following a bootloader unlock.
Edit: There's a distinct difference between a network unlock and a bootloader unlock, the former will nearly always also execute the latter, but the latter can be done by itself (obviously only on unbranded phones). The method of getting a custom ROM is basically network unlock > bootloader unlock > root > install custom kernel > install custom ROM. Root can be done before the unlocks, I believe.
I'm new to all this too, only trying to explain because I know how much of a total pain it was to work it all out .

Network lock stays away, updating probably won't lock it again, but no one has tried and we do not have any sure information

Ah, right. Makes everything at lot clearer thanks
So if I do unlock through the Wotanserver place, my bootloader will be unlocked but I wouldn't be able to get official ICS, but a just as good if not better copy? Is the ROM fully stable as in does everything function fine? I have heard of an ICS ROM which stopped HD recording on Xperias. Does this have any such problem?

Also, just a quick question to add: Do I have to go to SE to get my boot loader unlocked? Or will it automatically unlock with Flashtool when I flash the Kernel?
Thanks

Thanks for that, do you have a link for me which I can use?
And just generally, can I add that this is the way to get MiniCMSanwich ROM on my XMP:
Root (zerg's software) (not needed but useful so might as well do it then)
Unlock Bootloader (from SE's website or the link which hopefully the above poster/someone else gives me)
Kernel Installation (Flashtool)
Finally, flash the ROM and Gapps using Clockwork Mod Recovery
Thanks

It is the same unlock method, just everything brought to one place by that app maker.
Rooting your phone before custom ROM installation is not needed, because old ROM(stock) gets deleted anyway and custom ROMs include root already.

Is it possible to root the ultra without unlocking the bootloader? I'm not familiar with Sony, I haven't used a Sony phone since Xperia play. Or do I need to do the unlock method first?
Thanks in advance.

Bootloader Unlock

Hello,
I have been trying to research how bootloaders get unlocked without manufacturer help and not coming up with many results. I want to learn how to root and unlock bootloaders and create recoveries and everything to help out accessing and customizing devices, but trying to find things to read and learn about those topics hasn't turned up much helpful threads or info at all, if anyone could direct me to where I could learn how to do all those things that'd be awesome! Also, thinking about bootloader for vs990, could we not just take an unlocked t-mobile bootloader and customize to the correct paths and values for vs990? What about the kdz file, can that be used to modify the boot security and unlock the bootloader or not? Thanks for the info and your time in advanced!

That method doesn't work on vs990, Verizon locked it down so when you try to get to bootloader even through adb reboot bootloader it just reboots to the system. No fastboot commands possible.

Well we did just get root a week ago... So don't give up hope just yet, give it a little more time and hopefully they'll crack through the security or overwrite the boot partition all together or something so we can get custom roms.
As of 3/24/2016, they have not unlocked the bootloader nor made any recovery system for the LG V10.

Installing a custom recovery and ROM without unlocking bootloader? [E2303]

Hello people from XDA!
From what I have read time and time again while looking for a way to change my Bootloader unlock allowed:NO to YES, there should be a way to install a custom ROM and recovery without unlocking my bootloader (since it's apparently impossible to unlock it). And if there is a way, please let me know.
Additional information:
My device is rooted (Kingoroot)
I'd really apperciate some "light" on the subject. I've searched for weeks and there seem to be absolutely no threads regarding the subject, although there are people claiming they have done it.
Thanks in advance.
What Android version is your phone running? 5 or 6?
5; 6.0 hasn't been released in my region (Latin America)??

Flashing 5.0 FTF on locked BL and network LOCKED

Hello guys i have big troubles with my sony M4. I wanted to root the phone buy of course first i have to unlock the bootloader because it is on 6.0. But then i got Bootloader Unlock allowed: NO. So i tought if i change the firmware using flashtool to 5.0 i can root it using some of the premade rootkits for 5.0 and M4 but i have another problem. The phone is locked by T-mobile and they won't unlock it unless 2 years pass which is for 6 months from now, so if i install another firmware like the commercial 5.0 i think the network will not work right ? So guys do you have any other ideas how can i unlock the bootloader if the status is NO and also keep it locked within the network ? Thanks in advance.
