Flashing bootloader unlock image gets stuck on waiting for device. - Lenovo Zuk Z2 Pro Questions & Answers

My device is plugged in with the stock cable and it is booted into bootloader via adb reload bootloader.
I've tried both fastboot -i 0x2b4c flash unlock unlock_bootloader.img and fastboot -i 0x2b4c flash unlock unlock_bootloader.img, both result in stuck on waiting.

I had a similar thing happen to me when I did my unlocking, fastboot doesn't recognise your phone, what happens if you send "fastboot -i 0x2b4c devices"?
Eventually I did figure it out but I can't remember the solution, but one thing that did work all the time was mauronofrio's multi-tool. https://forum.xda-developers.com/zu...ol-tool-one-driversunlocktwrpfactory-t3432782
Have a go, see if that works.

Hi, SachK2.
When I faced the same issue, installing the custom USB drivers that are usually attached to the bootloader unlock topic did the trick to me.

I tried the multi-tool but it gets stuck and crashes on the command window. I cant find the custom drivers download.

posting the links to another forum is disallowed here, though if I were in your shoes, I'd go on 4pda, search there zuk z2 pro topic and download the drivers there - wasn't able to find those drivers within xda yet
I'll also PM you the direct link so that you can check [the registration might be needed to be able to view and download the files]

The very first thing I recommend you to do, is to download the right recovery and install it via command
Code:
fastboot flash recovery recovery.zip
Let me know if you run into any further troubles.

Hi,
Frist in boot loader check your OS version it should be something like 2.19.401.2 or lower than this.
NB: ALWAYS TRY WITH MORE THAN 75% BATTERY, AND THAT FOR ANY CODE TO WORK PROPERLY, MAKE SURE TO SELECT FASTBOOT BY POWER KEY IN BOOTLOADER
Anyway, if you can enter fastboot, then you have some chance of recovering your device and because you have S-Off it is going to be a bit difficult.
First download this stock boot file : https://mega.nz/#!lEAVwRSL!wrP2hi6GEYLeJaPf2ssZo9wCtSi7E4yfyUHgh3Q3XSs
Then place this file in the ADB folder, then run command :
To flash boot file command is:
Code:
- Fastboot Devices (this command is important to know if the device is connected and accepting and responding commands)
- fastboot flash boot boot_signed.mg (assuming this is the name you saved the file with)
- fastboot reboot bootloader
Also download Stock Recovery: https://mega.nz/#!gVJE1Bxa!6SwXStAD8p-XlnQiPkRcdNo_ITFD1ykn-tN6wIBVi1I
Place this in ADB folder and run command:
Code:
fastboot flash recovery stockrec.img // (assuming that is the name you have saved the file with), only after flashing this you will know if the device has any OS, if OS exists it will boot up.
fastboot erase cache
Attempt and let us know how it went...Good Luck

Remote command not allowed for unlocked bootloader

I want to flash custom recovery in my phone but it shows
remote: command not allowed
In bootloader, it shows that it is unlocked.
i get the same error when I type
fastboot oem devices-info
remote: command not allowed
I tried
fastboot oem unlock XXXXXXX(huawei code)
and it shows my phone already unlocked
and I tried
fastboot oem relock XXXXXXX
it shows
remote root type is risk
and I tried
fastboot oem lock
it shows
remote command not allowed
The recovery is still Huawei e-recovery, it asked me to download the update but it always failed when it comes to download package.
What should I do now?

To boot your recovery, disconnect from pc, press and hold power, vol up until a reboot, let go of power but keep the other pressed for about 5,6 sec more.

Hi all ! I had exactly the same issue... The problem was solved by using the TWRP-CN image pointed by Druger ! (thank you mate) Any other attempt resulted into a fail. Twrp is of course in chinese language but follow this, and your life will be a bed of roses : youtube.com/watch?v=KOhR92EKD7A
Hope this will help

this thread has continued to be unaswered for several years now.
only tested 2 phones... and it seems they both have bootloader status is unknown. i can do fastboot and recovery mode on the 2 phones but on fastboot mode.. only shows blank screen... idk why it's like that. i downgraded both phones to 12.2.0 version. and bootloader status is still unknown. it can be recognized by the computer in fastboot mode using fastboot devices command but you can't do anything to it. fastboot oem device-info does not work only shows .......... , fastboot oem unlock ....., only one working is fastboot adb_enable .. kinda useless. .. i gave up on unlocking the bootloader for this phone.. im too noob for this.

I opened this thread when I was still "noob-ish". The device's bootloader can't be unlocked. Unless someone hacks into it's bootloader (like LG L Fino), it might be possible.

I got root access with KingRoot and then flashed TWRP with Flashify.
Somehow that gave me access to bootloader without the necessity to downgrade the firmware.

Bootloop, flash locked. What can I do?

Short story: my phone bootloops (shows the Android One screen for 3 seconds, then reboots), and I cannot unlock the flash in fastboot. fastboot oem unlock fails, fastboot flashing unlock fails, fastboot flashing critical_unlock fails.
What can I do, is my phone definitely bricked?
Long story: I installed september OTA and then rooted with Magisk using the image patch method. Now I wanted to get October OTA, so uninstalled Magisk to recover the unpatched bootloader, but the OTA refused to install. So I tried the flash_all method, but it failed because I did not do the critical unlock. So I tried the fastboot flash critical_unlock, but it continuously refused to work.
So I decided to agan lock flash, and do the oem lock, to restart the unlock procedure from the beginning. But after locking, the phone does not boot anymore (and it was booting fine before!). On top of that, I cannot oem unlock anymore, fastboot oem unlock always fails.
Is there any way to recover the phone?
Try fastboot oem edl
then use mi flash
Thanks for help.
Unfortunately fastboot oem edl fails:
Code:
# fastboot oem edl
FAILED (remote: Device is already locked!)
Finished. Total time: 0.001s
And as fastboot oem unlock also fails, I cannot unlock the bootloader.

I'll need more info than that
what's the error you get when using oem unlock or unlock_critical?
are you using minimal adb? If so, don't, use this instead https://developer.android.com/studio/releases/platform-tools
Are you using a usb 3.0 port? Switch to a usb 2.0 if you are
I am working from Linux, and I have the full Android Studio installed. I cannot use adb, since I cannot boot the phone (and as far as I know, adb does not work on fastboot, but I might be wrong).
I will try with the one you linked and come back with the results.

Minimal adb includes fastboot, if you have minimal adb or you installed it from the repo then it's outdated, use the one I linked
Nothing was working for me, so finally I recovered the phone by opening it and using the deep flash method.

Flashing Unlock
Hey, make sure that you have first unlocked the bootloader with the fastboot command: "fastboot flashing unlock". Try it. It will erase all your data and do a reset factory and then you should be able to reboot your device normally. Also, it will let you flash the boot.img for root your device.

Did you let unlock bootloader and permitted the USB debbugin on the developers option before flash the boot.img?
Make sure you are using a USB 2.0 to connect your device to the PC. See if you PC recognizes the device into the fastboot menu with "fastboot devices", if doesn't, try reboot another phone with "adb rebbot bootloader", then enter "fastboot devices", your device should be listed into de the devices attached. Then try again entering "fastboot flashing unlock".

Oh, that could be a problem. Try to use this tool. I hope you can get your phone working again. If this doesn't works, try to flash the original boot.img of your firmware version.
