[Q] Problem about bootloader of SK17

Good day !
I have come across a situation of unknown bootloader of SK17 .
I found some shop in Hong Kong is selling some cheap SK17 (not sure if it is the same as SK17i) . I asked the shop keeper and they said that the bootloader is locked , but without SIM lock .
So , will someone confirm me if this situation is possible ? As I read some post in this form it indicate that locked bootloader is usually because it is branded , i.e. SIM locked . If it is SIM free version does it mean I can make the bootloader unlock ?
And , what if the system shows "Bootloader unlockable ? No" ? Is there any way to work around this issue to make the bootloader unlock ?
Thanks so much !

Hi!
A simlock is something totally different to the bootloader´s lock.
No Simlock means that you can use any sim of any provider you like and who´s band is supported by phone´s hardware.
The bootloader ist locked by sony basically to prevent people from removing the sony Firmware even if it is not branded. A second issue is probably to prevent people from unlocking and playing with the firmware who do not know what they do.
Before the lock of the bootloader it was easy for everyone with one-click-tools or similar to root the phone. This could have led to many RMA procedures at Sony
But there must be a possibility to unlock it due to the terms of open source software.
So there is no need for you to unlock the bootloader as it takes any simcard anyway.
What the issue about sk17i sk17 and sk17a is, I do not know yet. But I´m curious about it
hi... how to know that your xperia mini pro unlock already in bootloader?
my rooting status is,
Bootloader unlock allowed: YES
is it already unlock in bootloader?? or not
It meens that it is be allowed to unlock your bootloader. It means not that your bootloader *is* unlocked.
Hi Poedel ,
Yes I understand SIM locked and Bootloader locked is different . But I wish to install 3rd party roms (CM7 rulez) , so I still wish to know how to unlock the bootloader .
So maybe I change a little bit about my question .
1) a sim unlocked device with locked bootloader (bootloader unlock allowed : no) cannot unlock due to the SIM lock . Then will it allow to unlock if the device change to SIM unlocked ?
2) Any method to work around the locked bootloader (bootloader unlock allowed : no)
3) Any way to unlock the bootloader if IMEI code cannot be used to extract the unlock code ? As I know some of the shop will use flash rom writer to wipe with another device firmware and IMEI will changes (it happens last time when I buy a X01HT) .
Thanks a lot !

this is still confusing The simlock does not take care at all if there is a bootloader-lock or not. I never ask someone if I am allowed, definetly not mr. simlock
2) Any method to work around the locked bootloader (bootloader unlock allowed : no)

okay, usually you'll go to the sony's dev site bootloaderunlockl.sonyericsson.com (don't know the correct sub, could be correct) and authenticated by your IMEI and email you'll get the unlock code. Without IMEI you won't be able to unlock. But even if you IMEI changed you can try the current IMEI. What I think is that Sony just saves the Email and IMEI into a mySQL Database to cope with the situation if your device enters RMA à la "you unlocked, your fault". It would be rather not the way that they look if your current IMEI really belongs to the device there. I would simply try it. BUT!
There is a post where a method is shown to root your ph0ne without unlocking the bootloader.
So here are both links:
rooting without unlocking not tested by me (even not yet read *covering*)
default way like I did it
Dear Poedel ,
Thanks , that's exactly what I wish to know .
So in worst case if bootloader is not going to unlock in normal way , I should use the test point function to bypass it and flash another room and firmware into it , and unlock the bootloader again ?
Thanks very much !

[Q] Help with unlocking bootloader on Live (WT19i)

I have been trying for two days now to unlock the bootloader on a friend's Live with Walkman (Wt19i) with little success.
The phone came with firmware 4.0.2.A.0.58 and is branded so in the *#*#7378423#*#* /Service info/Configuration menu, the rooting status is :
Bootloader unlock allowed: No
Rooting was easy, thanks DoomLord.
Next is unlock bootloader. I tried to do this via the s1tool method because the official Sony method was a no-go because of branding.
The s1tool method seemed like it would work but then I read that it also doesn't work on branded phones.
I attempted it anyway - the result was no change whatsoever in the phone's bootloader status.
Can I unlock the bootloader without having to pay someone to do it?
The s1tool method might work even if the phone is branded but if you want to unlock the boot loader to flash custom kernels and roms you will need to enter to fast boot mode which is disabled in all the branded phones that I know of, you can try to enter the phone in fastboot mode turning it of and connecting the USB cable to the PC and the phone holding down the volume up key, if the notification led turn on blue then you can flash custom kernels and rooms once the bootloader is unlocked if not then you will need to pay to unlock it if that is what you or your friend wants.
Hope it's helpful!!
Thanks for your reply, very helpful indeed.
I will see if I can boot into that mode when I get back home and at least then I'll know for sure.
It would be ever-so-nice if I could unlock this for her without having to pay money for it. (She won it in a competition that she only entered because her iPhone died recently - but the Live WT19i is locked to the wrong network)

Well actually for a sim unlock at this moment you will need to pay for, there's no way to unlock the sim for free. Unlocking the bootloader it's a different matter than the sim. I didn't mention it because you were asking about the boot loader sorry.
And I stupidly assumed unlocking the bootloader would allow me to unlock the SIM lock/branding.
Thanks again for the help, I'll just tell her she has to pony up the dough if she wants to use it on her network.

[Question]Unlocking Bootloader & TurboSIM

Hey folks, I've been nugging around the bootloader unlocking problem, since I own a Neo V which is locked, and the service menu in the phone says that the Bootloader cannot be unlocked. So I've read through some threads about this, and I wondered upon the idea, if I unlock my SIM lock(probably with TurboSIM, since thats the cheapest solution), would that enable me to unlock my bootloader, and start the real modifying of my phone?
What do you guys think? Worth's a try?

Both are unrelated but often confused. Unlocking for a different cellular network and unlocking bootloader are completely different sadly.

SIM Unlock enables bootloader unlock?

Hey guys, my bootloader unlock allowed status is no, but what if i unlock my SIM? Will it change to Unlock Allowed: Yes? I really wanna unlock the bootloader.
SIM unlocking and bootloader unlocking are two unrelated things.
You won't unlock your bootloader by unlocking the SIM.
To be exact, there is no way to unlock your bootloader by your own if bootloader unlocking is not allowed.
If your local laws grants you the right to gain full access over your device, you can try to send your device to Sony and ask them to unlock the bootloader by invoking these laws.
There is no guarantee that Sony will accepts to proceed, but I know that at least one person get an unlocked phone in France using this process (sorry I don't have the link anymore, I will add it later if I find it again).
Hope it helps,
Regards

Possible bootloader unlock for H860N?

Hi all, I recently found a procedure at the link below to possibly unlock the bootloader for the H860 using Windows 10 (Not sure if it works with other OS) I dont own the phone myself (yet) so was hoping someone could try it out. Can someone try please?
Disclaimer: Try this at your own risk to your device, Im just providing the info.
https://www.hardreset.info/devices/lg/lg-g5-h860n/faq/faq/lg-bootloader-unlock/
Goodluck!
This won't probably work at all. It's the standard procedure for unlocking a bootloader locked without a key. It was possible to use this method on some early firmware of the H830, but not on the H860N. You can try if you want, there's no risk at all in that procedure (except for the data erasing ); it won't work (99,9% probabilities), but if you succeed you will make the joy of all H860N owners

"It's the standard procedure for unlocking a bootloader locked without a key."
How do I know if my bootloader is locked with a key?
Does Enable OEM unlock option in Developer mode mean my bootloader is unlockable?
Thanks
OEM unlock option should be available on the menu regardless of the locking status of your phone. You can try the procedure for unlocking without the key; if your bootloader needs a key, the procedure just won't work.
