Unlock bootloader without any OS [urgent] - Xperia Z Q&A, Help & Troubleshooting

Hello there,
I know that it will be noobish for some people here, but for me is a big problem. I have Sony Xperia Z (L36h) C6603 which my wife bought for me as a present some years ago. Following the guides here in the forum I updated to RR rom 7.1.2. Everything was great, just the battery was holding not even full day. So I decided to return back to stock firmware and here is what happened:
I used Flashtool as it was said in one tutorial, I flashed the Commercial and Journalist (10.5.A.0.230), I locked the bootloader through Flashtool and I was waiting for the device to boot. Until now (already 2 weeks) I`m waiting for it to boot connected on the charger, but it shows the waves, the Sony Xperia logo and than black screen. Today I tried to unlock the bootloader with Flashtool, it takes me to the menu where it`s saying to disconnect the device, to power it off (I wait 30 secs after powering it off), to press the volume down and to connect the usb cable. The light on the right side of Sony goes red, than green. And that`s it. The menu how to put my phone in flash mode still stays there and nothing else happens. The same is when I try to flash other firmware with Flashtool. I tried Emma but it shows that the bootloader is locked and it`s sending me to Sony`s website to unlock it, through Emma I saw the IMEI and I got the unlock code (but how when I don`t have OS/FW to input the code?). If you know any chance to flash a stock firmware or any other CM/RR, TWRP in my case please tell me. I will try everything to fix it, because the phone is special for me.
Thanks in advance.

Unlocking failed
I got my IMEI from Emma and requested unlock code from unlockbootloader.sonymobile.com, using fastboot.exe I tried to unlock the bootloader and everything seemed to be fine, but Emma still shows that the device is locked. I`ll post the fastboot.exe output:
C:\Users\ruthless\Desktop>fastboot.exe -i 0x0fce getvar version
version: 0.5
finished. total time: -0.000s
C:\Users\ruthless\Desktop>fastboot.exe -i 0x0fce oem unlock 0x2E24******99A7DE (6 digits replaced with * )

@DooMLoRD need your help ;(

Did you find a solution?
I'm stucked at the same point. My xperia z is allowed to unlock bootloader and fastboot unlock seems everything fine, but Emma still says is locked.
Thank you

[c6603][AOSP] Strange bootloader issue

I would try to be as descriptive as possible.
Check if BLU allowed:
Dial *#*#7378423#*#*
Service info > Configuration > Rooting Status. It says Bootoader unlock allowed: yes
Go to SONY official webpage to get the unlock key. http://unlockbootloader.sonymobile.com/instructions
Enter the IMEI code and get the KEY in mail.
Put the phone in fastboot mode.
Code:
D:\>fastboot -i 0x0fce getvar version
version: 0.5
finished. total time: 0.002s
D:\>fastboot -i 0x0fce oem unlock 0xMYKEYINRIGHTCASE
...
FAILED (remote: Command did not succeed)
finished. total time: 0.036s
Curiously if I run the second command again, it succeeds.
Code:
D:\>fastboot -i 0x0fce oem unlock 0xMYKEYINRIGHTCASE
...
OKAY [ 0.171s]
finished. total time: 0.172s
Now if my bootloader is not supposed to be unlocked or the key is wrong then I believe the behavior should be consistent and should always FAIL. Unfortunately that is not the case. What is worse is that when now I do
Code:
D:> fastboot reboot
rebooting...
finished. total time: 0.002s
It does not reboot anymore and goes into boot loop. The only way out is to flash the stock ROM using flashtool and get it back.
What I really want to do:
Build and flash AOSP 4.3 onto the device. I have already build it and also downloaded pre-build img from one of the threads. Using fastboot flash works for boot, system and userdata on second attempt just like bootloader. However fastboot flash cache fails consistently. Rebooting again put me back into boot loop.
Is there any way to find out if the bootloader is actually unlocked or not?
I would appreciate any help in debugging/troubleshooting this problem. Looking forward.
P.S.: Not sure if this belongs here or in development forum.
bump up.
Any help would be appreciated from devs.
Go to configuration again and check rooting status. If you are truly unlocked, it will say:-
Bootloader unlocked: Yes

Thanks for responding. But unfortunately for me as soon as I run the oem unlock command twice, it does not boot anymore and I have to reflash it again. Post reflash when I go back I still see the previous status.
Adding some background:
This issue occurred only after I reflashed the stock ROM using SONY companion. This might have locked the bootloader again and corrupted the process of unlocking it. Is this a possibility? Any body who had similar problem?
Could you reflash to stock and check the bootloader unlock status? If you can reflash via PC Companion, it usually means that your bootloader was not unlocked. If yours was unlocked, it would fail and you would have to use Emma instead.

No. If you can repair your phone via PC Companion, your bootloader is locked. Only if you are unable to do that with an error code along the lines of "This phone's software has been modified" then your bootloader is unlocked. Flashtool works regardless of bootloader unlock status.

I can repair which essentially means that the bootloader is locked. However I still see the configuration saying bootloader unlock allowed to be yes. Strange that i am not able to unlock it.

MRA58R Unable to relock bootloader

Hey all. I'm coming back from a custom ROM/kernel and I've successfully flashed the latest factory image. However, fastboot is spitting out an error when I go to relock the bootloader. Here's the output:
C:\Users\***>fastboot flashing lock
...
OKAY [ 0.002s]

After I issue the command my N6's screen goes unresponsive for a few minutes, after which I can still use the volume keys to navigate the bootloader. However, after a reboot, the device is still unlocked.
Has anyone else encountered this issue?
Try using "fastboot OEM lock". Fastboot flashing lock is only for the 5X/6P from what I understand.

I don't know why it refuses to relock but another question: why do you want it to be relocked? It is adviced to only relock a bootloader when it is absolutely needed (warranty case, resale...)

Question about

Hi everybody, I have a little question regarding my P10.
The model of my phone is VTR-L09C521B101
Is there a way to flash this phone with VTR-L09C432 version?
or i need to flash with same model version (VTR-L09C521)?
Thnks
Yes, it is possible to 'rebrand'. The procedure is explained in the Mate 9 forum. It is not so easy and involves unlocking the bootloader.
Updating can be done with the Firmware Finder (Playstore).

thanks for the answer!!
regarding bootloader, the phone shows this:
PHONE RELOCKED
FRP LOCK
ADB shows me that the phone is unlocked, the problem is when I try to send something to phone it shows:
Error Remote command not allowed.
any ideas?
thanks!
I've tried to reword the mate 9 instructions for the p10 here: https://forum.xda-developers.com/p10/help/rebrand-firmware-finder-t3685951
As for adb, what command are you trying? Do you see your phone if you type ADB Devices?

The Strange thing is that in the phone shows PHONE RELOCKED, not unlocked as ADB shows.
Since I uploaded boot img of another version (C432) full OTA, could this be the problem? in this case what can I do?
thanks for your help!!
Could this be happening because of FRP Lock?, none of the software I have tried (DC-phoenix, chimera and Unlocker v2) worked. Im this close to throw this f*ckin phone to trash u.u

edit: just found this in another thread "FRP Lock occurs when the phone has a firmware mismatch and or oem unlocking is not on in developer options"
Hmm, i've just checked my phone and in fastboot it says PHONE Locked, and FRP Unlock. I think that may be your issue. What exactly did you do to flash your phone with the other version? put an UPDATE.APP into a \Dload folder and 3 button update?
is your phone booting (guessing not). my guess is that you need to get a hold of your stock firmware file an flash that first.

Ok, this is what I've done step by step:
1.- With the unlock code provided by huawei, I have unlocked my phone (my version is VTR-L09C521B101 stock)
2.- Once unlocked, I have downloaded another ROM version (VTR-L29C605B151) in the web page says this rom is for latin america), so with the Huawei Update Extractor, I have extracted all files.
3.- Via ADB/FASTBOOT, I sent the files to my phone, boot.img first and then the others. (big big mistake!)
4.- Rebooted the phone, and then keeps restarting at huawei logo.
5.- Seeing that it did´t worked, what I did was to lock the phone again thinking to send it to Huawei (at this point the phone shows as "unlocked" via fastboot commands, however when I start the phone in fastboot mode, in the screen shows "PHONE RELOCKED, FRP LOCK"
6.- Sent to huawei's service, they said that they cannot fix my phone because it was tampered/rooted.
7.- Right now all I need to fix my phone is to LOCK/UNLOCK again in order to rebrand it to L29 version, since the original stock rom dont exist (not as FULL OTA).
And that´s what I did so far my friend.
Questions:
1.- Is there a way to connect to my phone and change the oem info file? or something?
2.- Do I need to wait the stock rom to be released in order to reflash via Dload method?
3.- What if the stock ROM version of my phone is never released?
thank you for your answer my friend!!
Hmm ok. I am just not sure on your step 3, I've never heard of a method that involves a boot.img... what I would suggest, is to try and download the stock firmware files (need the larger full ota files), extract the update.app file and put on sd card in \dload.
Then hold down both volume up and down and power (3 button method)
It will try and flash the stock image back to the phone.
I just tried the Dload method and nothing happened (always stuck in 5%), now im going to try to use a smaller memory card (mine is 64 Gb). lood

Same thing happened to me. When you get your unique identifier find an online generator and then paste that into the Motorola website, worked for me.

Hi,
For Working this command "Fastboot oem get_unlock_data"
First you need to remove or delete your phone's SCREEN LOCKS like your fingerprint, face-unlock, pattern or password etc... And keep on NONE option in lock screen. After all above procedure done than, You run that commend "Fastboot oem get_unlock_data". After runing thant command, You will not get "FAILED (remote: unknown command)"
It will work 200%.

Did you try another USB port? Some users reported that USB 3.0 did not work but 2.0.
I would be willing to bet this is happening on devices that are not allowed to be unlocked. Like those purchased from a phone company.
its been a week since i'm trying on my htc 10, but getting the same error, i tried,
- delete the drivers and re-install
- delete sync manager
- enabled debug & oem unlock
- done reset factory for the phone
- change USB ports and cables
- tried 3 latops
nothing works, sometimes i'll just the error "waiting for any phone" and other times "FAILED (remote: unknown command)"

I'm following a tutorial and obviously got stuck and the very same step as you did. And presumably you are following a tutorial, too.
1. Go to Security Settings and remove device lock (PIN, fingerprint, whatever you are using) and set it to NONE.
2. Go to Developer Settings and Unlock Bootloader. (If you skip step 1., you'll be asked to unlock your device here, but find that the Unlocking failed afterwards. Hence, go to step 1. and remove the lock first.)
3. fastboot oem unlock
Done. (Bootloader is unlocked now. Confirm via boot to fastboot mode (Volume down + Power button))
fastboot oem get_unlock_data is probably removed (deprecated) and maybe you don't even need a key from the manufacturer to unlock anymore.

You still need a key to unlock the bootloader for the first time! When it's locked with status "flashing_locked" you don't need a key for it.
Is it a brand new device...?

If that question refers to my post: I have a Moto E4 (XT1762). Bought it like half a year ago to tinker around with. I started it, ran all updates available and set a device lock (here: PIN).
Today I finally found the time to get started with lineageos and followed the guide at: rootmygalaxy.net (download-and-install-lineage-os-16-on-motorola-moto-e4-android-9-0-pie)
I got stuck at the error the OP had. (This lead me here.)
In my case I got past the error by doing the steps mentioned in my first post, i.e.
1. started the device (normal boot) and got rid of the device lock (PIN in my case), enabled USB debugging, enabled bootloader unlocking
2. powered off the device and started it again in fast boot mode (volume down + power button)
3. On computer / in terminal: fastboot oem unlock (without any key from the manufacturer)
The device showed a confirmation dialog. (Volume up: Yes, Volume down: No)
Code:
[email protected]:~/downloads/lineageos/Android_SDK_platform_tools/platform-tools$ ./fastboot oem unlock
(bootloader) Start unlock flow
OKAY [ 9.657s]
Finished. Total time: 9.667s
Now in fast boot screen I see Device Status: unlocked
I just wanted to share my experiences from today's struggles and maybe it'll help the OP.

If your friend was able to flash custom ROM, he had to have Bootloader unlocked.
It means that he did have Bootloader code - he had to keep it because same Bootloader code is good for the same phone for the whole life. Unfortunately, people didn't dare to care about that, similarly like not caring to learn first (before they bricked the phones) about what and how to flash - this is unfortunately one of the reasons (bad posts on Internet) that Huawei changed the policy about BL codes (and now everyone, also those who do care what and how) suffer.
Anyway, for P9 you can still buy the BL code for 4-5 USD.
Also, if they returned the phone unbricked, with MM, you should be able to upgrade to Nougat by DLOAD, not needing to unlock BL (ir they didn't put c300 MM)

Thanks for your reply, now cant flash anything < . I try to fix what can be fixed, he has the code but now when doesn't work or something is wrong, when try with ADB to unlock bootloader (.. "FAILED > emote: Command not allowed) also FRP LOCK .
i try many version with DLOAD but does not work! < Maybe can give me to try it ! another thing when try to format It seems not working only 2 % .fact now I do not know what to do with his phone but I will try!
To unlock FRP, you must unlock OEM from Settings, Development menu.
As you described, phone was bootable (to MM) when returned from service - but now, after the failed DLOADing, etc, is it bootable any more
You cannot DLOAD any P9 firmware to any P9 phone. Firmware must be:
- of the same model and cust (otherwise you first needed to rebrand)
- it must be shown eg in FirmwareFinder as FullOTA-MF-PV (not just FullOTA-MF)
If not cared about (specially about model and cust) - no wonder if it bricked the phone
If you cannot boot anymore to read full model, cust and build number from Settings, About, you can read from Fastboot (switch off, connect to PC, press and keep pressing Vol-, boot by Pow). You will need ADB & Fastboot installed on your PC - if not, search for Minimal ADB and Fastboot on XDA and install.
You can copy to bat file and execute:
Code:
fastboot devices
PAUSE
fastboot oem get-bootinfo
PAUSE
fastboot oem get-product-model
PAUSE
fastboot getvar vendorcountry
PAUSE
fastboot oem get-build-number
PAUSE
fastboot oem oeminforead-SYSTEM_VERSION

According to:
Code:
(bootloader) locked
your Bootloader is locked.
Does the Fastboot show also FRP locked?
And you cannot login to Android (to unlock OEM=FRP)?
According to:
Code:
(bootloader) EVA-L19
vendorcountry: hw/meafnaf
Your P9 should be L19 (dual SIM), and you had c185 Middle East cust.
From your previous posts, phone was on MM (EMUI 4), maybe you successfully upgraded to Nougat (EMUI 5)
But according to:
Code:
(bootloader) :System 8.0.0.046(0OHZ)
you attempted to flash some Oreo (EMUI 8) - and that bricked the phone?!

It's bricked since you flashed Oreo Bootloader over the MM or N firmware, and hence it also does not accept DLOAD
To fix, you would need to flash by Fastboot, but Bootloader is locked and you are not allowed to.
To unlock BL you would need to unlock FRP, but due to the brick you cannot enter to System to unlock OEM/FRP
Hence you are stuck…
-You can try one more DLOAD by downloading this package:
https://androidhost.ru/bN4
You will have to unzip/untar (whatever applies), you should find a folder Docs inside with the Installation guide.
This is official package for DLOAD repair (P9 L19 c185 b403) for Huawei service shops, but I'm not sure would it work over your bricked Bootlloader from Oreo
-Certainly you could recover by TestPoints (but you can also definitely brick the phone by one wrong move there),
but it requires openening back-cover, short-connecting two pins and flashing the appropriate bord firmware (you would also need TestPoints drivers).
It's risky, TG I never need it, if you want to learn about you will need to search on the Net and XDA
-Otherwise, due to the facts as above, I can only recommend you to seek for the paid help from DC Phoenix:
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
Ask them in advance, it might cost you cca 20 EU credits (tools and instructions for unlocking FRP and Bootloader, unbricking and flashing official Nouga firmware).
You can probably arrange also for debranding to L19 c432 Nougat if you wish
If you would then want to rebrand and upgrade to AL10 c00 b540 Oreo, you will have to start with:
- unbricked phone with latest Nougat firmware
- having Bootloader code ready
and to carefully follow OP instructions from this thread:

I can't believe the phone back to work again!
How to bring the phone back to life and to work? The phone was restarting at the Huawei logo, adb not working and I have bootloader code but not working FPR looked and bootloader looked
Dload not working , so what I do , try use DC phoneix and go forward the bootloader unlocked and FPR but unfortunately must phone go to update mode but unfortunately now stuck again with no fastboot and no recovery !
finally I try with testpoint with IDM and Huawei bored and working!
and upgrade or install system with dload
After that install Android 7 and update to Oreo 8 with TWRP ?.
