A number of us have posted here saying that SIM unlocking doesn't change the bootloader unlock status.

All the XSP devs and more experience XDA users say do not try to unlock Sony bootloader if the status says no.

When the bootloader status is set to no, fastboot mode is disabled so it isn't possible to "just try" to unlock the bootloader.

So, when you say "you believe, it should", what exactly are you suggesting?
[Xperia SP General] dh.harald:
Yes, it's a fact :(

Yes, i've no fastboot mode, so can't unlock it... In flashmode, you can't do it...

It's sad, but i've no further idea, how to unlock my bootloader :(
[Xperia SP General] raziel123:
Custom Roms

It's not all doom and gloom guys,

even if you cannot unlock bootloader, there are still custom (stock based) tweaked roms which you can flash ...

[Xperia SP General] shelleyfrank:
No mate. SIM unlocking doesn't unlock the bootloader. I aught to know, because I had my XPERIA J SIM-unlocked not long ago. After the unlock had been applied, which was a code unlock, the bootloader unlock status remained at NOT ALLOWED.

I used to own an Xperia X10i and I got the phone unlocked via USB using an internet service. On that occasion the SIM locks were removed, as well as the bootloader lock. I was pretty inexperienced then, and I have no recollection of the phone's bootloader-unlock status before the operation. In fact, at the time I didn't even know what a bootloader-unlock would mean for me. In all likelihood the phone's bootloader-unlock status was set to ALLOWED without me knowing it. If not, I probably hit upon a service, now de-funked, that could unlock a NOT ALLOWED bootloader, at least on an X10. That is very unlikely, since there would've been traces of it on the web, and I couldn't fine any yet.

You can imagine, I am dyeing to get the bootloader unlocked on my Xperia J, but at the moment I am only dying of despondency.

hi there.

i don't know if that has already been posted, but:

we athletes from austrian ski federation get phones from A1, market leader in austria. The paper (a describtion which comes with the phone) says, that all phones are sim-locked (what makes sense, because I assume A1 is normally not so stupid to let the phones sim-unlocked when they give away their phones for free).

As I switched from my good old galaxy s2 to the xperia sp, I read the paper and was disappointed, because i knew that there is just a little chance to unlock the bootloader.

so i went into service menu and it says: bootloader unlock allowed: YES!

So: either it is possible to switch the bootloader status to yes, even if it is sim-locked - or my phone is just a lucky case - or it has no sim lock. As i have no other sim-card, is there a way to find that out?

i hope i could help a little bit.

greets
[Xperia SP General] Shywim:
To check if your phone is sim locked, go into the service menu, Service Info -> SIM Lock. If nothing is checked, then your phone is unlocked.

my friend I bought xperia play it's had bootloader unlock '' no i was so frustrated , the method of test point using s1tool didn't work with me , the only hope i had is that i have heard someone here unlock the bootloader that says ''no'' for pay , so I got it to place of teh shop repairer phones here in Morocco i told the man there my issue with bootloader unlock says no' he said come on i will unlock it now and he did unlocked it and now it's says ''yes '' : D i was like wow , i checked him I found out he used a software similar of S1tool named setooL with a box named smart card , i think they bought the server to unlock bootloaders and the simcard ; they use the same method of test point like in S1tool :) i hope I helped you :) sorry for my bad English : D
[Xperia SP General] zincir:
I've pretty much come to the terms unlocking on my own is unlikely to happen, but I still haven't figured out how the private mobile shops do it, I mean it has to be just some software but nobody mentions anything about that.
[Xperia SP General] thehritzinator:
Exactly what I've been thinking! How has nobody gotten to the root of this yet??
[Xperia SP General] mman1982:
Hi,

I think Xperia play is simply unlockable by the testpoint method(it has,old security btw)..so that's why this shop can do it.
[Xperia SP General] coombes69:
I would love to be able to unlock my bootloader on my XSP but cant find information anywhere.

Hi All,

I suspect there's something between sim unlock and S1boot unlock bootloader. A guy with 12w19 unlocked the bootloader with S1Boot AFTER removed simlock. He NOT have fasboot, BUT he can flash kernel from TFT files! See: http://xdaforums.com/showthread.php?p=53000030

Can someone try it? (after unlocked SIM lock, try to unlock with S1Boot testpoint. If your R..changes r, then you can flash TFT kernels with flashtool)

Why don't you try it yourself? Why put phones of others at risk?

Hi,

Because atm i have no possibility to remove simlock from my phone. By the way, there is no risk i think..in the worst case you got a packet timeout at S1tool...nothing else.
[Xperia SP General] TheHunk_2:

Flash this with flashtool if you have unlocked sim-lock and you still have unlock bootloader allowed: no status.

Warning! It's untested.
[Xperia SP General] korenisko:
Pay attention. You can hard brick your xperia
[Xperia SP General] MrSteve555:
Well, this would be possible if we knew, how to get the phone into Semc Zeus flash device mode(there is no accesible testpoint on the device). Also, it's possible to get custom kernels running WITHOUT unlocking simlock(my good old neo V is rocking CM11 with locked simlock and no fastboot ;)).

I'm sure that if some devs work on it, it would be easily done, but they just don't care about poor forever locked devices.

For now, there are four ways to go:

1. Get some attention of XSP devs and make kexec working(hard and time-consuming, but the best method of getting custom kernels and Muliboot working on locked BL's)

2. Use ramdisk hijack by [MENTION=2591365]dh.harald[/MENTION], [MENTION=301295]kerai[/MENTION]nFTW and [MENTION=5765508]bagyusz[/MENTION].

3. Use kernel modules to get custom kernel features on stock(but there are no kernel modules for XSP, maybe in future they will apear on xda...)

4. Get experienced dev's attention and make fastboot working on locked devices(i don't expect this to happen EVER, but it's totally possible).
[Xperia SP General] thehritzinator:
Can anyone verify if this works??
[Xperia SP General] dukevyner:
I would but i'm a little scared it might just be something i heard about if you change something in the phone like "bootloader unlock=0" to =1 it hard bricks the phone so... i wont try
[Xperia SP General] MrSteve555:
I'm sure it won't brick your phone. Yes, it does mess with TA partition, but it won't modify anything that could cause the phone to brick.

tied it on a c306

flashed new ftf. then this doesnt work

[Xperia SP General] audit13:
Thanks for testing it out. I have a c5306 and was tempted to try it.
[Xperia SP General] shahrukhqasim:
For point 3, you mean this:

http://xdaforums.com/xperia-sp/development/heard-sony-kernel-sources-available-t2807961

Sources are available. Can they somehow be adopted for locked bootloaders?

Anyway the thing is CM11 works on locked bootloaders. At least, we can port all the CM11 based ROMs for Xperia SP. It should be simple, right? That way, difference between locked and unlocked bootloaders will reduce by a big amount.
[Xperia SP General] MrSteve555:
Source of stock kernel was available for a long time. However, it was distributed in form of Open Source tarballs on Sony developer site. So it doesn't change anything - it's still nothing interesting for LBL users, as they need signed kernel. And there is no way to sign the kernel, because we would need to get Sony private keys.

CM11 is available, yeah, sure. But it's not "the mighty thing". It's running on stock kernel, so that holds us from using some real magic stuff. It's just a ramdisk hijack. And kexec replaces kernel...
[Xperia SP General] shahrukhqasim:
So can't we request Sony to get the kernel signed? Only problem they should have should be with those whose devices are locked to a specific carrier which somehow can be implemented in that kernel that they remain locked.

Is the FASTBOOT present on locked bootloaders? I have tried so much; I never was able to get it to fastboot. In the udev rules, the mode for flashtool is 0777. For fastboot, it should be 0600 or 0666. I have tried both but it does not go to fastboot. Is it not possible to flash a kernel from flashtool mode? Like kholk was able to bypass the security on motorolla droid razr, same can be done for our device; can it not?
[Xperia SP General] alvlin:
I unlocked my bootloader, but bravia enging dont work now :(
[Xperia SP General] Gamm86:
Happens when you unlock your bootloader. It's due to lost DRM keys.

Relocking won't make your BE work again unless you restore the TA partition (which contains DRM keys for Bravia Engine) that you must have backed up before unlocking your bootloader.

Another option to get BE working again is explained here: http://xdaforums.com/xperia-u/general/howto-bravia-engine-music-info-t2301489

The above fix will only work on stock Sony ROM's though.
[Xperia SP General] MisterGame7Web:
How did you succeed ?????
[Xperia SP General] MrSteve555:
http://speedy.sh/RTB4H/C5303-Fastboot-TEST.ftf

I searched for some time, and found out that one way could enable the allowed:YES flag.

But there is a risk connected with flashing this - it can brick your phone, and you will have to restore it with testpoint.

So only experienced people that know all the risks should flash this, preferably without simlock, but simlock-locked people also can try.

It's untested, and I just want some testers, but I'm not responsible for any bricks that will happen.
[Xperia SP General] Jeik:
So,guys,my c5303 says that bootloader unlock is a big,fat NO.

I feel like someone kicked me in the junk...

And there is no way of bypassing the "NO" ?

I want to be sure,so that my subconsciousness stops poking me with "unlock the damn bootloader if you caaaaaaaan" Dx
[Xperia SP General] neXus PRIME:
Where did you get this¿??? And how does it work???
[Xperia SP General] MrSteve555:
In Sony firmwares there is a small file downloaded every time named simlock.ta(it's in the encrypted FILE set) Flashtool ignores that file every time when flashing, but it messes with 7DA and changes ROOTING_ALLOWED flag to 1. I tried renaming it to preset.ta, but as someone said, it throws out a signature error. Probably it would work only on SIM-unlocked phones, where the 7DA isn't checked. So I need to somehow find out how to flash it properly, maybe renaming it to cust-reset.ta would work, as the files have the same structure

Ofc there is a manual way, but it's for someone who knows how to hex edit TA - it's replacing the 7DA part in the TA partition.
[Xperia SP General] neXus PRIME:
I have sim unlocked set. =0

But its too risky for me to test. I have not enough money to get it repaired or replaced if this fails. If there are few success reports, then i wud give it a shot.
[Xperia SP General] mrjraider:
Perhaps an idea to look for diffrences between both unlocked allowed yes and no?

~~ Regards
[Xperia SP General] neXus PRIME:
Yes, it's already done. Devs found the differences but not the method. And no way to flash that.

Maybe some day after I've sold this they'll find. But I'm keeping it for at least a year
[Xperia SP General] mrjraider:
So if I understood all the comments right.. There is a way to modify the files so that you can unlock it but there is no way to install/flash them without messing it up?

~~ Regards
[Xperia SP General] MrSteve555:
Hmm, there is a way to modify the files, and there is a way to flash them without messing everything up. But it requires SIM-unlocked phone and if someone decides to do that, he/she must be experienced in that kind of things.

It's basically:

1. SIM-unlocking the phone

2. Getting TA partition dump from the phone.

3. Hex-editing the TA dump with 7DA values from CE1 simlock.ta.

4. Flashing the modifed TA to the phones.

Honestly, looking at some cases when bl unlock allowed: no changed to yes after flashing stock firmware, it must be connected to simlock.ta file, because it's the only file that messes with TA partition.
[Xperia SP General] neXus PRIME:
Which case??? i havent seen a single confirmed case. If there is, i am also sim unlocked.
[Xperia SP General] MrSteve555:
There were some people in Xperia U forums that changed their bl status when they flashed stock firmware of their operator with SUS or PCC after they unlocked the SIMlock. Seems like BL status is connected with Simlock. Also I saw that in some simlock.ta files there is no trace of ROOTING_ALLOWED flag - so maybe it's "dynamic" - when you flash simlock.ta, the flag changes depending on SIMlock...
[Xperia SP General] neXus PRIME:
Chances of brick??? hard brick.
[Xperia SP General] MrSteve555:
There is no chances of brick when flashing said operator firmware, the simlock.ta will only be flashed when the phone is "ready". But with manual editing there is big chance that something goes wrong, so I don't reccomend that.
[Xperia SP General] Dn.Thanujaya91:

[Xperia SP General] croxray:

HI, I bought my Xperia and it was already sim unlocked. The bootloader unlockable status says no, but I can enter the fastboot mode normally. Does this mean I can go ahead with unlocking the bootloader? Can I brick my phone if I try to do it? Beacuase it is not blocking the fastboot mode. I own Xperia Z2 but I havent found similair posts for my device but I believe this is similair for every xperia phone. I would really like to unlock my bootloader so someone please help :)
[Xperia SP General] ricodredd:
If you can enter fastboot mode then you can at least try to unlock it once you have the unlock code. It shouldn't brick your phone but it will wipe it. so you'd better have an FTF file handy to flash back on it if it unlocks successfully.

And if anyone still thinks that removing the SIM lock will change the bootloader unlock status from NO to YES, it certainly didn't for me. It's a carrier provided phone which has the SIM lock removed but I don't even have fastboot on my phone :(
[Xperia SP General] mman1982:

[Xperia SP General] Kaffeetrinker:
Open your phone and look for the testpoints. There aren't any.

There could be a method anyway.

You can completely rewrite the whole internal memory. You have to solder cables to the tiniest contacts you've ever seen and get some equipment that is more expensive than your phone. Oh and it' quite risky.

You can and may do everything. The question is whether you're able to do it or not. I am not able to do the mentioned method by the way.

[Xperia SP General] Kaffeetrinker:
OK, there are some testpoints. But they can't unlock the bootloader!

The SP has a totally different hardware than the phones which you could apply the testpoint method to.

What do you expect? That we keep a secret about tespoint method that we will keep until we will have been asked about it enough times?

If you want, try the testpoint method and kill your phone... IT WON'T UNLOCK YOUR BOOTLOADERV!
