[Q] XZU Bootlooping NO Recovery LOCKED Bootloader - Sony Xperia Z Ultra

Hey guys,
I just experimented with some sound libraries and so on...
now my device is bricked.
I don't get into recovery (pink led, not turning on), flashtool does not allow me to reflash the stock-rom, and fastboot-flashing also doesn't work, because my bootloader is locked.
Is there any possibility to unlock the bootloader from outside, without having the stock-rom running?
Or any other possibility to get this thing working again?
Would be really happy, if someone has an idea
Thanks

Flashtool (EMMA) says, my bootloader is locked -> I have to unlock it but thats not possible without a running system. for flashtool I just pressed vol down and put the cable in like it is described everywhere.
for fastboot I did the same, but vol up. Then the LED turns blue, but I can't even reboot it via fastboot command.
USB-Debugging is also deactivated, so I don't know how to access the phone.
EDIT: just tried again: reboot over fastboot works, but erasing or formatting is not allowed. Flashing not possible because there is not enough space it says
EDIT II: ok, just got the bootloader unlocked via fastboot. now trying to get the stock system on to enable usb debugging and flash custom rom then
EDIT III: just solved it. how? 1. Unlock bootloader via fastboot 2. let EMMA do a service 3. enjoy again

[Q] Wt19i - Question regarding access to fastboot & unlock bootloader

For the sake of this question I have a locked bootloader on a wt19i. The phone is rooted. (It's my friend's phone but I'm voicing a theory). It can't enter fastboot mode and the bootloader unlock status is: not allowed.
Armed with the IMEI number,
If I did a TA backup via Octopus Suite 1.0.3,
Then, (following methods seen in this thread: http://goo.gl/QNKxS Third post down.) to force the phone into fastboot, start a firmware (re)install in PC Companion. During that process the phone will enter fastboot mode. If I stop the process there [in Windows Task Manger], then the phone will get stuck booting only into fastboot mode (until I finish putting firmware .tft back on it).
THEN I use SE Bootloader Unlocking v1.6 {Found here: http://goo.gl/JxDmY }. I give it my IMEI, it gets an unlock code and I connect the phone - in fastboot - and select "Unlock BL" to unlock the bootloader.
Then restore TA, followed by a restore of firmware.
Would this unlock the bootloader or brick the phone?
Corrections and answers welcome.

I checked the thread you were referring to,
the process they are doing there is to access flash mode...
fastboot is completely different, can only be accessed if bootloader is unlocked.
based also on the bootloader unlock status: not allowed, this means phone is network locked, unlocking of bootloader would not work thru available methods in xda.
you would to pay in order to remove the network lock and then unlock bootloader
Would this unlock the bootloader or brick the phone?

This would not unlock the bootloader,
Brick the phone, not sure, but it would probably wont, good thing you have a backup.
You can always do a flashing of stock firmware thru flashtool or wotanserver.

your bootloader is unlocked.
You can check the state if you boot phone up, open dialer, type *#*#7378423#*#* -> Service Info -> Configuration
Please tell us what it says there, then we can help you

The problem is you tried to use that tool and the moment you have typed your IMEI and pressed get unlock code, you lost your warranty. So you have no warranty anymore!!
Now you will have to desimlock and after that you can just hope fasboot is enabled.
Install flashtool, open the installation folder > drivers and install all drivers for all devices. Install the android sdk (please better look in my signature to see how to set up android sdk and flashtool and replace the usb drivers). Then try to enter fastboot mode like explained in the threads

Need help with bricked Redmi Note 3 Pro (Kenzo/Snapdragon)

Dear Community,
I got my Note 3 Pro Snapdragon Version today and I tried unlocking the bootloader, installing root and TWRP.
Unfortunately after I installed TWRP, WiFi didnt work anymore so I wanted to go back to where I was before.
i tried flashing the GlobalRom with the MiFlash Tool but somehow I'm now stuck with a bootloop.
The phone starts up and shows the MI Logo but doesnt go on. I tried booting TWRP temporarily via fastboot commands so that I can try to flash flashable zip files
but it doesnt let me execute "fastboot boot xyz.img" anymore because my device is locked.
I would really love to hear any solutions or ideas. I dont want any root or something anymore. If someone has an idea Im very happy!!!
thanks a lot in advance and tell me if you need any more infos

1. keep vol + and vol - pressed while connecting USB to enter adb mode
2. check if phone is connected with "adb devices" in command line, if phone shows up, enter "adb reboot edl"
3. now you can flash via MiFlash

First of all, HUGE thanks for your fast answer!
Unfortunately I couldnt get this to work. Since I am stuck at the Logog screen here is what I tried:
Pressing both volume buttons while Logo Screen and plugging USB.
Pressing both colume buttons while fastboot screen is up.
These two didnt enter adb mode, I guess because of the bootloop I'm in
I also tried antering recovery mode with volume up + power button. Pressing both volume buttons didnt help either but when I am in recovery like that it shows my device in adb as "sideload" device.
Maybe that helps ? Can you give further advice or am I doomed?
My idea would be: Is it possible to reflash the device completely only usinf fastboot? The only thing I seem to be able to enter is fastboot...
Is there a way from fastboot to "working phone" ?
or maybe through the "adb sideload" state?
thanks a lot in advance!
Paul
EDIT
tried installing via "adb sideload xyz.zip" command but after shortly showing a status bar on phone screen it aborted and said "Total xfer: 0.00x" on PC screen .
Also: I read "adb reboot edl" brings you to download mode so you can flash something. Tried it but the phone just rebooted the normal system, so it stuck on Logo again...
search miui forum for unbrick, there is 2 or 3 method without opening your device

Unfortunately they all do not work because they always require either a phone in download mode, and i only get to fastboot and adb sideboard or they require flashing something via fastboot but I can't do that either because it says my device is locked if I try...
Any suggestions how to flash a ROM with fastboot only or with adb sideload?

I Had The Same Issue Brother ! There are only 2 Things which you can do now .
1. Test Point Method to enter EDL
2.Give it to Service Center . I Gave Mine to Service Center ,They Fixed it in 30 mins or less and it was free

Can I do the test point thing myself or is it risky?
What kind of service center? A general mobile phone repair shop or a Xiaomi special one?

I've been facing the same (or a similar?) problem about a week ago but managed to get out. Knowing me for having a head like a sieve I made some notes, sadly quite rudimentary
Did you try to flash with MiFlash after "adb reboot edl"? If I remember rightly after "adb reboot edl" you got the logo like booting another way, but the light is blinking red. Then I could flash via MiFlash.
I'm quite sure that if you get a "reboot" after entering "adb reboot edl", your phone will be in edl mode.
I will try that this evening when I am at home again and report. Thanks

Do you have another idea? :/
How did you unlock the bootloader, via official permission or that unofficial hack?

Only options you have right now are:
1) using test points method which is a but cumbersome and voids warranty if you care about that.
2) go to a xiaomi service center of you have any nearby.
It is hard bricked.
So there is absolutely no option to unlock bootlader via adb sideload or fastboot ?

Apparently, no! Whenever using unofficial methods, read precautions carefully and you missed all as I can see. Wait if someone can help you out.

That sounds nice and easy. I already applied for official unlock.
But: do you know if u can use the official unlock now? I can only access fastboot and adb sideload mode. Is it possible to activate official unlock from there? Or do I need a working ROM rather?
I would have thought that official unlock doesn't work from fastboot /adb sideload...

I have the same problem. I made the same mistakes as shisaya24. I have followed every procedure for unbricking and nothing works. I even applied for an unlock code and got it from Xiomi. I used their mi-unlock app which requires fastboot (pwr/vol-) but it gets to 50% and bombs out. It states it can't verify the phone. Can anyone please help me??

out of sheer desperation I tried MiPhone again and after a few tries, MiPhone started updating the OS. My phone now works again and I have an unlock code as well.

Completely f****d my G-Watch

SO, tl;dr-- My LG G watch turns on, then enters into a point where it is stuck doing the swirling colors boot animation until the battery dies. If I boot into bootloader mode, I cannot do anything other than reboot bootloader or power off. Recovery does not work, when I try it gives me the android guy on his back and tapping the screen does nothing. The restore tool used to be able to interface with my device, but now it does not even show up under 'adb devices.' If anyone could tell me something I can do, it would be greatly appreciated.
Is your bootloader unlocked?
Yes, I have an unlocked bootloader. When I turn the device on, it shows the little 'unlocked' symbol.
If you boot to bootloader mode can you run fastboot commands? If so, download one of the 6.0.1 roms from XDA and then follow the install instructions. If not....hmmm, not sure!

How do I do fastboot commands? I can boot to bootloader mode, and the restore tool talks with my watch and recognizes it as a device sometimes.
Via a USB cable connected to a computer and the fastboot tool installed on that computer. You also need the correct fastboot drivers for this.

Fastboot mode won't stay

I am trying to install stock firmware through fastboot. After typing below command,
Code:
adb reboot bootloader
the Device reboots but Fastboot mode only shows for 1 second then the Device reboots to system.
I have Usb debugging ON, OEM unlocking ON
Tried on 2 different PC's. Also tried removing Usb after command.
Reason for stock flashing is just that I used this ADB command on my phone and It lost IMEI: By this method and here is the detailed problem.
UPDATE: Took the phone to service center, they changed the Mainboard. But then Fingerprint was not working (couldn't enroll). They took it again and tried stock flash and fingerprint sensor change but the issue persists, still diagnosing.

Can I achieve this without voiding my phones warranty?
I finally took the device to service center. And the executive said he would send the case to Realme and he is not certain that it would be covered under warranty as the imei is broken. But my device's bootloader is untouched and I never tried rooting.

I already found the solution, but it will erase your data.
with the adb commands you must restart the device in boorloader mode:
adb reboot bootloader
Then when I take you to the bootloader screen what you have to write next:
fastboot oem lock
(Remember the phone will be erased)
then to restart the device you have to:
fastboot reboot
And the device will reboot.
what you do is lock it, so that you can then unlock it in a simple way.
(If you do not know what the ADB is, warn man), I hope it helps you and those who enter here too :good:
@l3dson: Be careful before relocking the bootloader: The phone MUST be 100% stock or you will have a brick.
@Mohammedbi: Your bootloader is still unlocked, even after flashing the KDZ. It's just the newly flashed ROM doesn't know it, and you don't need it to.
Just go to fastboot (PowerOff, Vol- while plugging in cable) and flash TWRP. Follow ChazzMatt's root guide for the initial TWRP steps.

What exactly is not working?
ADB doesn't require Enable OEM Unlock to be set. Just plug it in and ADB away - unless drivers or cable or port aren't working.
And your bootloader is still unlocked if it was unlocked before you flashed stock Oreo. You should be able to enter fastboot using the steps described in the post just before yours.
Edit: Of course you have to enable USB debugging in order to use ADB. I'm sure you knew that

hey i have this same problem and been asking around... but the adb reboot command will not work because it says the phone must be "enabled oem unlock" mode before you can use adb commands... which is greyed out..so back to square one... how to enable it?? any suggestions on this??
