Download Flashtool from this link install it, run it and follow the bootloader unlock process, enter the code received from sony and unlock it.

How is that supposed to work if the Bootloader is locked ?
Make sure you have USB debugging enabled
It is probably only a minor oversight that hinders it from succeeding
Also remove the screenshots( too much info)

You need to create a text file called ulcode.txt containing the unlock code you received from Sony. Then put this file in a folder with your device (phone) name (eg. My device name is CB5A2B7CSV yours should be something similar. You can get the name using fastboot command devices. I see the name of your device in the first line of the third image you posted above!). Then put this folder inside the following path (create the necessary folders):
C:\users\your defult user name\.flashTool\mydevices
Then unlock your bootloader using flash tool. It will take your unlock code from the above mentioned text file and asks for permission for unlocking and will unlock the bootloader smoothly.
Good luck

s-off error waiting for device

Hi!
i follow the guide to s-off the device in the htc site, driver and all is installed but fastboot stuck on waiting for device... anyone have this problem?
I thought the SXL didnt have S-off yet? possibly you tried S-off for the wrong phone..
no no I checked my version is unlockable! Type the command to extract the codes I still waiting on device ... What can be? 2 days that I feel!
What do you mean that your version is unlockable? I know some SXL phones come shipped with S-off, but when they come locked there is no way to unlock yet..
You sure you dont have the sensation XE?
He probably means his bootloader can be unlocked

Sorry i'm confused whit the root...(version can be rooted) but i think my bootlaoader is unlockable!! the problem is fastboot.exe that don't recognizes the phone!!
all fastboot command don't work (waiting for device error)
Make sure that you are booted into that bootloader thing, to get there: take out battery, restart phone + volume down, then when device is started into the bootloader and connected to USB you should be able to make the blue text go to fastboot with volume up/down. Then try unlocking again, it should work..
ok token extracted but when i press submit after i paste the token, received this error: Unlocking Bootloader Failed!
Sorry it didn't work out. Here's why:
We're sorry, but it appears your attempt to unlock the bootloader on this device has failed. This could be caused by several factors including simple errors in the entry of the unlock token, problems with your device, or a lack of manufacturer support for the unlocking process. Please see the specific error code listed below, and try again if necessary.
Error Code: Invalid Bootloader Token Length.
Error Reason: The submitted Token appears to be the wrong length and won\'t work.
ok reset the phone and S-OFF!!
this two step are required???
1. You cant just flash a custom rom on this phone, firstly you will need the 'Chinese rom' which is here http://www.filefactory.com/file/c2ec...511_101713.zip and make sure it is on the SDcard part of your phones memory. Make sure it on the root of the SDcard because it will be easier to find later. Then you will need this rom RCMix3d Runny XL rom from here http://dl.dropbox.com/u/56143145/RCM...ny_XL_v1.2.zip (thanks to benjamin.j.goodwin) and make sure that is on the SDcard too with the other rom
2. Then you will need to download this file from here http://forum.xda-developers.com/show...7&postcount=18 it is the 'Chinese boot.img' and will need flashing from fastboot again. So put the phone in fastboot and extract the 'boot.img' from the 'boot.rar' file and put it in the fastboot folder on the PC. Open the command prompt again and type this... fastboot flash boot boot.img ... This should only need doing once if you're coming from a stock rom.
what is it for???
I dont know why, but it has to be done. It only has to be done once, after that you can happily flash whatever you want

Here is a step by step with pictures, please try the procedure again. Ensure that all the requirements are met. You might want to copy and paste the commands to make sure they are correct.
Yes boss I do the exact method as htcdav mentioned and place all the required files the fastboot folder but no clue what mistake I make .
What should be unlock_code.bin file size ?when I download it the file shows 1kb it's right ?

Is USB Debugging enabled in Settings -> Developer options?
Is Fast boot disabled in Setting -> Power?
Double check to make sure, then try the command again! Double check spelling and capitalization. If you are unable to get this to work, if you go S-OFF with firewater you will be able to unlock your bootloader during that procedure.
Yes, Unlock_code.bin is 1 kb.

Majmoz bro tried your suggestions and my phone bootloader is unlock now tnx for the help .
Now kindly just tell me one thing more can it be downgraded from 4.3 to 4.2 or 4.2.1 version phone is unlock and shows message on no service and some time limited service appear on top and phone show full signal bar when I inset sim Internet is working but can't make calls and messages help in this regard if possible

You can downgrade only if you are S-OFF. With S-ON you can only flash the same version or higher RUU & Firmware.
And could be installed a custom rom like cygenmod etc ? Now phone has no service issue

Search the web or your carrier's site for their APN. Check it against what is in your phone Settings -> Mobile network settings -. Access Point Names -> <Carriername> Data
If it matches then it is something else, if not, then you will have to add the settings by selecting the three dot menu -> Add
Where you able to make calls before you unlocked the bootloader?
You might also search for a newer radio for your phone, I remember seeing a thread but I can not recall where it was at.
Most roms don't include the radio, it is in the firmware.
Boss tnx for your time !
But will it not be an hardware issue ?

Yeah, me too. sToRm// is taking a look at it, at will include it in XperiFix. But it's still important to notice, that it's a fix, and not a DRM backup / restore solution, so the original TA partition / DRM keys will still be lost and won't be recoverable.

Yes, it's a one way step and you're reliant on the developer bringing a new version of the fix each time there's a firmware update.
No offence to the developer, but I know nothing of M-Rom or aledoom, it would be good to know a little of their background before I open my phone to some software from a unkown forum.
Since nobody bothered to give an answer...
1. Go to the Sony Bootloader Unlock page here
2. Follow the steps for the Xperia XZ
3. Get the email, click the link, type in your IMEI
4. Follow the instructions on the page.

It looks more like you didn't bother to read OP's post.
He has already done all that, he's asking why the unlock command isn't working.
Unfortunately, up until recently, unlocking the bootloader on this phone is extremely unappealing, so like almost no one has tried unlocking it, and those who did probably didn't run into this problem, so no one was able to offer an actual answer.
The first reply actually provided some suggestions. If you bothered to read.

Hi, I have maybe the same issue :
Code:
fastboot -i 0x0fce oem unlock 0xMyKey
returns only
Code:
...
and seems stuck : nothing happens.
So I would like to unlock my bootloader, but I cannot manage to do it (of course *#*#7378423#*#* then Service info > Configuration > Rooting Status Bootloader unlock allowed says Yes).
How did you manage to unlock your bootloader?

I did not find a proper solution. It is still impossible to unlock my XZ1c with my laptop. Fortunately, I did manage to unlock it using my (very) old former laptop (it’s 32 bits, I had to use the old ADB v23), and it worked like a charm.
I don’t know why it failed on my current laptop (either with my usual OS Linux, nor with Windows 10).
Old thread is old? i don't care. because i want to say that looks like Sony finally give the XZ1c into the data base and there is a hot to guide over the Dev mode of the Phone. i will past the Sony guide to it here so this info will spread where it needed:
"To be able to unlock your Xperia XZ1 Compact, prepare it by following these steps:
Go into Settings > About phone and tap seven times on Build number to enable developer options.
From Settings, go into Developer options and enable OEM unlocking.
Warning:
Camera stops working on certain software releases.
Device protection features will not work on this device while this setting is turned on. Note: It will only be possible to unlock the boot loader for certain releases. You can check if it is possible to unlock the boot loader of your device in the service menu by following the steps below:
In your device, open the dialer 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.

/€: Again, you guys are way to deep into the matter and i found several things that was never mention by any tutorial.
after several testings and also failings i will add: under windows 10, you have to check the Drivers double and make sure you use one that works!
EVEN IF IT APPEARS THAT THE DRIVER IS CORRECT IT MAY NOT THE CASE!
To check this you have to use "ADB DEVICES" and "FASTBOOT DEVICES".
Only if your device appears in the list IN BOTH (!) cases the driver setting is correct. This is very important.
Also you have to consider that after reboot into bootloader ("adb reboot bootloader") the device will NOT RECOGNIZE (!) by windows and appears as new device without any driver! (check Device Manager for this) so you can't access it in that state EVEN it was recognized before!
You have to install the Google Android USB Driver in this case. Also you have to check if the device appears still in both (adb, fastboot) lists.
Only then you can preform the Guides correctly!
summary: you have to install two (!) driver to get proper access to your device, one driver can only be installed in a certain state of your device (bootloader state) you have to make sure that your device is accessible in all states to preform your unlocking AND img pushing correctly.
Your bootloader is unlocked if on Power up the message appears "Your device has been is unlocked and can't be trusted. Your device will boot in 5 seconds"
...and now i go and found a way to get rid of the "non access on external cards for apps" _feature_ ...ands no all the tools and images and guides DON'T WORK.

So how did you manage to work this out? I have this exact problem. When the phone is in fast mode (volume up) it shows in the "fastboot devices" but not in the "adb devices". When it's turned on it does show up in "adb devices" but (obviously) not in fastboot devices...
As it is, when i try the "fastboot -i 0x0fce oem unlock 0x<insert your unlock code>" it tells me that it doesn't know command -- i. I have found nothing about this problem at all. nowhere. I'm tried to unlock the bootloader (settings, show it's possible) for 5h and haven't managed to do it yet... I'm really thinking about sending it back, this is just too annoying... please please help me...

Have you checked that your phone can be unlocked?
Some providers sell phones that can't be unlocked so that they don't have to deal with the warranty mess.
Open your phone and type *#*#7378423#*#* - then look under Service info\Configuration under Rooting status it should say Bootloader unlock allowed: Yes
If it says No, then you need to stop, there is no way round this.

I bought it straight from amazon without any carriers but yes it is allowed (that's what I meant with "settings show it's possible", sorry if that was unclear).

I got the same problem, I just removed the "-i 0x0fc" part, so it became "fastboot oem unlock 0x<insert your unlock code>".
I think there may be a newer version of fastboot that lacks the -i option.

Your mention of "Volume up" button indicates that your try to reboot it per button pressing. Try to avoid that. Your device should reboot by typing in the fast boot command and press enter. then you have to check the driver state in the Device manager and their install the correct driver (Google ADB driver). Don't unplug your Phone during this.

Huawei p8 lite 2017 bricked after wrong oem flash

(SOLVED) So I wanted to debrand my phone, and I saw this post https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903
problem is, the oem I flashed with twrp was for the p9 lite, now my phone doesn't boot inside the os, it only goes to huawei erecovery but the download always fails. I can boot to fastboot mode but everything I try to do it says command not allowed, only fastboot devices work
I hope someone can help me as I really need my phone for work, thanks very much
my original cust was C02
I also have a twrp backup I did, but I just cant get inside twrp because as soon the phone turns on it goes to erecovery
Edit: i finally resolved and I'm going to really help you if you flashed the wrong oem file just like me, just follow these steps:
1. since you installed a new oeminfo, you are gonna need to unlock the bootloader again, (just like you did the first time), but wait! here is what I did wrong, when you request an unlock code, huawei in the unlock page is gonna ask you for your imei and serial number, I was lazy and I got my imei via fastboot instead of checking the one on my phone's box, worst idea ever because when you flash another oem your imei is gonna change so that's why in the site it said sn and imei are mismatching, so take the IMEI on your phone's box and NOT via fastboot. Anyway, let's go to part 2
2. in the unlocking site they are gonna ask for a product id wich you can get by writing *#*#1357946#*#* in the phone's dialpad, but you're probably thinking "how can I do that if my phone does't boot the os?" but don't worry my brudda! just download this https://cloud.mail.ru/public/KGmS/1cEhHg1G6 , open it and chose huawei y300-0100 as product model, then put your IMEI (take the one from your phone's box!!) and it's gonna give you the product id you need in the huawei site.
3. once they give you the unlocking password, power off your huawei and connect it in your pc with your usb while holding the volume down button, you should go in fastboot mode
4. once you are in fastboot mode write in the cmd fastboot oem unlock (9982883838382365) <<(instead of this numbers write the unlocking password they gave you in the huawei unlocking site) aaaand done, you unlocked the bootloader once again.
5. if you previously had twrp (before flashing the wrong oem file) it's gonna pop up when you boot the phone, now you can use fastboot or twrp again to flash the right oem (or stock rom)
I REALLY HOPE I'M GONNA HELP YOU BECAUSE I KNOW HOW BAD IT FEELS WHEN YOU BRICK YOUR DEVICE LIKE I DID!!
Now bye everyone I need to go play soccer and I'm late

So I wanted to debrand my phone, and I saw this post https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903
problem is, the oem I flashed with twrp was for the p9 lite, now my phone doesn't boot inside the os, it only goes to huawei erecovery but the download always fails. I can boot to fastboot mode but everything I try to do it says command not allowed, only fastboot devices work
I hope someone can help me as I really need my phone for work, thanks very much

FRP status? (in fastboot)
Phone status? (in fastboot)
unlock the bootloader again, even if it says its locked, after that fastboot should work fine. then you can try again booting into twrp and flash the right oeminfo

have you used windows for unlocking?
if yes windows 10?
if yes have you used powershell?
if yes press arrow up until you see fastboot oem unlock "number", copy the number (it's the code!!!)
if no .... idk i'll do some research

Good luck

thanks for helping me XD and by the way I checked my imei on a site and it says that my device is a p9 (what the heck?) I guess I need to install some p9 files to make my phone work again?
grazie

I got it directly in the site I also tried this method https://forum.xda-developers.com/p9/help/how-to-product-id-bricked-p9-t3561156
but when I click on commit after writing all in the huawei unlock site bars it says SN and IMEI are mismatched
I mean you really f***ed up there. I thought that you could restore the device by eRecovery but If you would do that you would brick it completely bc it would Download everything for the p9...
you can't do anything without the unlock Code.
You could otherwise try to force upgrade via dload

You could try this Generator https://cloud.mail.ru/public/KGmS/1cEhHg1G6
or DC unlocker (costs money)
You can use Firmware finder for PC and eRecovery DNS method to restore your phone to any firmware you want

A new thought about unlocking the bootloader of SO-02K

it is well-known that the bootloader of SO-02K is often unlockable.
with little knowledge of sony devices,i bought a SO-02K mistakenly.
i tried my best to provide any thought to unlocked it.
after a lot of research work i found a software that isn't free and it's really expensive when compared with the price of SO-02k.
the software is called qunlocked tool.
sourcepage:
带vmp壳的qunlocktool - 『脱壳破解讨论求助区』 - 吾爱破解 - LCG - LSG |安卓破解|病毒分析|www.52pojie.cn
从万能的群友那里弄到一份工具,说能解锁某尼手机,解锁一次要接近200块钱首先查壳打开软件点击check credits然后就根据bad username,OD载入,跟随401000删除分析 ... 带vmp壳的qunlocktool ,吾爱破解 - LCG - LSG |安卓破解|病毒分析|www.52pojie.cn
www.52pojie.cn
this software could be downloaded here:
qUnlockTool.exe - 蓝奏云
文件大小:3.7 M|
topjohnwu.lanzous.com
the software first check the credits with the server and if the account had the credits,which is sold about $25 per credit,then will calculate a unlockcode for the device,and then unlocked the device.
i didn't pay for it,since i had no acess to either google or paypal.
there is a old chinese proverb goes that "wan neng de tao bao",which means you could pay to someone on the web site Taobao.com to solve almost anything, so i just turn to it.
form one advertisement i found the process of the software,which is also mentioned in the source page.
i found that the unlocked code calculated by the software is simply "1234567890ABCDEF",which is too easy to be an unlock code.
i tried to unlock my own phone with the code,but it failed.
i guess the software may have 2 ways to unlock xperia phones:
1:the fastboot itself provides the ways to use extra functions defined by manufactors,which won't be shown with just simple command line like "fastboot -h",e,g :"fastboot oem unlock"
maybe the sony had define 2 functions like "fastboot oem unlock","fastboot oem unlock2",then they uses "fastboot oem unlock" to verify whether you had the right,if yes,then turn to "fastboot oem unlock2" to do the real process of bootloader unlock.
2:the software had do something to my phone ,cheated my phone to recognize the fake code.
maybe someone would help?

@hupengwei
The tool is legit? What was the bootloader unlock status before "Bootloader unlock allowed: No"? One thought on the alternate fastboot unlock command is a value known as remoteUnlock. You could extract the .exe with 7zip to further unravel the unlocking commands utilized along with decompiling other files code (if neccessary). Have an XZs that could benefit from this as it is currently "Bootloader unlock allowed: No"

In fact I donn know either the software is legit nor how the software works.i just guess it may work in 2 ways.in fact it is not only the fastboot.exe provided by Sony but also any fastboot.exe works.
I'll try the remote unlock command,but could kindly tell me how you get the commands?

I didn't get the command from the bootloader; there is a value that is stored on some phones in the device info known as RemoteUnlockState. Finding all the commands for the bootloader will require digging through Qualcomm's documentation and/or finding something that has been leaked indicating other commands able to be used. My guess isn't neccessarily correct, but I think you are right, there are other commands that allow rooting the device and those commands must have some other context that can be found withing a module or system (i.e. SELinux).
$25 to unlock a device thought to be unlockable. I'd have paid already to find out.

Here's the thread with the info to do so. Post your experience, feedback, results, and device used.

My post is directed at owners of a SO-02K.
Did it work?
The tool works. I already unlocked a bunch of Japan locked Xperia phones. i.e XZ3, 5, 1 .
