[Q] Bootloader - General Questions and Answers

Hi all
I just wanted to confirm something and put my mind at rest. I really don't like the idea of all the O2 branding or bloatware on my Sony Xperia Z1 (C6903). After typing in the *#*#7378423#*#* code into my phone, my Bootloader unlocking status is set to NO.
Does that really mean there is absolutely nothing I can to to Root my phone and get rid of my carriers control and stupid branding? And if not, why is this?
Thank you
David.

Well it may be hard to root it, but you'll have to find an external method to unlock the bootloader. Look for other methods. Till now I can only tell you to disable these carrier applications.

Unlocking bootloader in Sony Xperia U?

Already did a search and readings. I read that if the "bootloader" option is not present in Service info, Settings after dialing *#*#7378423#*#*, it's not possible to unlock by normal means.
Then I read that, by "releasing" the device from the vendor (unlocking sim), I get the option for unlocking bootloader, but since I'm in Mexico this is not an option. Vendor is monopoly and kind of "tricky" or "unreliable".
So I'm here to ask you if there's a way to unlock this phone, even if it was a long or difficult one. I want to install custom roms on it...
Thanks.
Someone?

[Q] Xperia J is possible to unlock BL with test point method??

Hi,
I did research using uncle google but I can't find any good answer.
So the question is: Is possible to unlock boot loader with any other method than official sony web site?
I'm interested if it's even test point method because on my J "Bootloader unlock Status" says No.
Maybe I should flash something jet like simlock.sin?
Any ideas?
Phone was sim locked before but it is already (sim) unlocked by code, unfortunately status remain the same.
Can anyone help with that?

[Q] Sony Xperia U network unlock

It's probably a n00b question so apologies in advance, but if I root / bootloader unlock and Cyanogenmod flash an Android phone that's locked to a certain network, will that network lock be removed along with the official default Android ROM? Or is the lock at something like a BIOS level (or whatever the smartphone equivalent of a BIOS is)?
I bought a pre-unlocked Xperia U about a year ago that I've been using on Vodafone and had to return it under warranty (got stuck in a boot loop despite the fact that it's totally unmodified, not even rooted, honest!) and the replacement they sent back is locked to Virgin Mobile. They're telling me that the phone I sent them was originally sold to Virgin in France and locked to Virgin before I bought it, and that they've therefore fulfilled their responsibility. So I'm just wondering now about unlocking, and I've always been curious anyway about how / if bootloader unlocking, custom ROMs etc are related to network unlocking.
Thanks in advance for any help you can provide with this!

well u can unlock it.. by getting the code from sony..
It will also unlock the ph..'s Sim lock..
Or ask the sony officialy for this.. they'll provide u every info required.
But unlocking the bl will do the job for you to be sim free
But do double check this from google too.
Also before unlocking pls make a backup as it will wipe everything from the device.
Just unlock and don't flash any custom kernels.If you want to then do it carefully pls with a backup and a copy of flashable stock rom.
Flash custom roms based on stock kernels
Hope this will answer the query..
Thanks for your reply! I spoke to Sony and they just told me to contact the network (which have done and they're wanting to charge me a fee to provide the unlock code). So to clarify, if I root the phone and unlock the bootloader, the network SIM lock will also be removed?

Not by rooting but also i guess not even by unlocking bl..
how much are they charging exactly..
i'll try to find the link for this
Also check this that how many times is the code applied for unlocking..it should not be 0
use this *#*#7378243#*#* in dialer
then service info sim lock

When I dial that number, the number just disappears. What is it for? They want £15.32 for the code. Should I just pay them and forget about trying to remove the lock?

Sorry the code is this
*#*#7378423#*#*
check the sim lock counters should be zero in all..
if zero then once u can try googling the code for unlocking if they work then it's great.
if not then it would be better to pay them for this as its a bit risky..
and are u using virgin's network??
As it's cheaper what they areaskingfor i guess.

Block in Vodafone network

Hi,
I am a beginner. I reag this http://forum.xda-developers.com/showthread.php?t=2743694
I just bought an Xperia phone M2. It is block in the Vodafone network.
"Bootloader unlock not allowed"
What to do, what are the steps to use it on another network?
Thank you,
There is no way around it I am afraid. Your bootloader cannot be unlocked and that's it. I am in the same boat as you, except mine is from T-mobile. The only thing that we can hope for is that someone will find a way to root the Xperia's M2 stock 4.3.2 rom without flashing a custom kernel or recovery. Hopefully there will be custom roms based on stock in future, but we can forget about roms like CM, Paranoid etc.
Oh and btw, simlock is not the same thing as perma locked bootloader. You can remove the simlock, but that won't change the "Bootloader unlock allowed:" to "Yes". This was already confirmed in the Xperia SP forums. There were rumors that custom mobile shops can change the bootloader status, but we are yet to see any confirmation about this. Also, even if they can do it, it is still questionable if the fastboot mode will be there at all.
Thancs!
Here is a way to unlock your M2 http://www.xperiacodes.com/shop/unlock-sony-xperia/unlock-sony-xperia-m2/

Unlocking bootloader imposible

Well, hello to everyone. I bought Sony Xperia Z3 and bought code to unlock it for all sim cards and it works. When i visited Sony's site for unlocking bootloader i came across this post:
In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Well, my device cannot be unlocked because it says No..
so what can i do to unlock it?

What? Do you know what you are taking about..
Anyway, if the service menu says you cannot do it then it is impossible to unlock it.

Why unlock it? You will lose your DRM keys if you do..

For your device it is not allowed, so you can't unlock the bootloader.
/I've read some threads about trying to unlock the bl although service says "no" on other Devices like z Ultra:
It's not impossible to unlock the bl with official method if you know your device earlier had status allowed "yes".

its necessity if you want an aosp rom .....
Stock basted Roms on most Sony devices are pretty fast and solid in my opinion no need to really unlock unless your desperate for cm
So that's it? If the bootloader can't be unlocked officially, I'm stuck on Sony roms forever?
Wouldn't bother me so much but my Z3 has a horrible bug where it doesn't work with the bluetooth in my car without rebooting first every time. Was hoping to install CM12.
Could be a hardware fault the Bluetooth

It's not that I have any major issues with Sony roms, I'd just like to be able to flash other stuff in the future, should I want to.
I'm still going to keep the Z3, such a nice phone, nothing else really comes close to it for me yet. Maybe the M9, but I just got the Z3 for £260 from o2 and had it network unlocked, probably have been looking at least double that for the HTC.
You can still root the device and customize it. Tools like the XPosed framework are great at modifying specific parts of the ROM.
But to confirm: you're stuck. You can't unlock Sony's unlockable bootloader. I've heard of people trying to unlock it, I've never heard of a successful case.
Enjoy the phone, it's among the best available right now (imho).
