Hi Team,
i am using Lenovo ZUK Z1 , morning today, after restarting the phone manually, device has gone into endless restart loop, i can boot onto recovery menu as well as fastboot mode, from what i have read so far i have to flash Factory image, to be able to bring this to a usable state, i would like to tell you that i cannot get the bootloader to unlock since OEM unlock option in developer option is disabled, i dont have any custom recovery installed, neither can i use adb commands since USB debugging is disabled, i have tried factor reset but the phone still continue to reboot and optimizes apps, what should i do to get out of this?
I would like to apologize if i have failed to convey my point properly, also please pardon my ignorance, since this is my very first question on this forum
Thanks in advance.

I'm new to rooting and all of this type of thing, i figured I would first start with my HTC Flyer. I successfully unlocked the bootloader, and installed SuperUser, upon installing greenify and i tried to install the Xposed Framework, and my device now is stuck in a boot loop.
When enter the bootloader and do a factory reset or try to enter factory it completely freezes, and when i try to connect it to my PC via fastboot the PC says that the USB device that is connected cannot be recognized and fastboot will not work. Did i completely fry this device? Also if you have time I couldnt figure out a proper way to flash a custom rom so if anyone has a guide for that I would appreciate a link to that as well.
Thank you so much!!
Okay, so i am using a xperia z2, cant rmb the version of the firmware, but i successfully rooted my device so i went on to try and flash cm11 onto my device. However, upon flashing cm11 and gapps into my phone through dual recovery i was no longer able to boot up my phone. Holding the power switch causes the device to vibrate, like perhaps every two seconds, but does nothing meaningful. Holding the powerswitch and the volume up key boots into fast boot, which is just a blank screen, but with the blue led that i read on the internet meant fastboot. Problem is, I am unable to get windows to install the relevant drivers for S1 Fastboot as it is displayed on my device manager window, and nothing i try will help. Ive downloaded usb drivers from numerous sources, including but not limited to flashtool, and nothing can get the fastboot to be recognised by the computer. Kindly advise on what i could do to restore my phone please! any help is greatly appreciated!!!!
I live in Singapore and i understand that bootloaders are by default unlocked? I'm not sure if i have to install any form of kernel , but i have a feeling this may be the cause of the problem? Please be kind, I am new to this entire rooting business. Once again any assistance is greatly appreciated!

Folow this to unbrick your device
You need an unlocked bootloader to flash cm11, no bootloader comes unlocked
There is unlockable and non unlockable
Hello, I've ran into some trouble with my nexus 9. After the last update my device seems to be bricked, just stuck on the white "google" logo during start up.
I'm trying to flash OEM android on my device and have been unsuccessful because my bootloader seems to be locked, and the only way I can find online is to do it through developer options which I cannot access now since my device is bricked. I've tried the fastboot command oem unlock and permission is denied. Prior to this I have not enabled developer option or usb debugging because I was ok with using stock software.
I can get into bootloader mode and access fastboot USB but I cannot flash my device due to bootloader being locked!
I've also tried Recovery -> wipe all data, and my device is still bricked afterwards!
Is there anything I can do at this point?
I've been running stock software the whole time! Never rooted / unlocked my device.
Forget about it.
Talk to the vendor (google / amazon / etc) the device is FUBAR
I am getting a new one, since there is no way to fix this.
period.
sorry for everyone affected, but google said, that there is no way to fix it.
damn..just called google and they said they will get back to me next week. this is pretty sad

It seems, I have the same problem. I tried to wipe it several times, it is no use.
Maybe I am completely dumb, but could one not sideload from 5.1.1. to 5.0.2.?
adb sideload <>
is about the only thing that is working. I don't know, how ota-files are created.
Have you tried this?

Put Device in Fastboot mode:
Power and Volume down,
then in the bootloader, go to fastboot.
With the fastboot tool (google), type:
fastboot format cache
fastboot format:ext4 userdata
It fixed it for some users, because wiping the userdata is apparently different from a factory reset in the boot loader.
For me, it did not work out: I did not end in a boot loop but in a neverending boot sequence.
Trying to flash 5.1.1 on my N6; now stuck on colored dot bootloop. Tried fastboot format cache and fastboot format userdata; both fail because the bootloader is locked.
Google has completely ruined this. I've owned the Galaxy Nexus, Nexus 4, and Nexus 5, and I *never* had a single issue doing simple **** like this on those phones. Here, everything fails. All the time. This time it's failed hard enough, evidently, to cause a permanent brick. Thanks a lot, Google.
Hi guys, i got the Huawei Y6 SCL-L01 phone and i wanted to install a custom rom, so i tried to install TWRP first, but since there wasn't a Y6 version (there isn't a Y6 version for anything pf ) i used the P8 version and it installed but when it rebooted the phone was stuck at a screen that say FASTBOOT & RESCUE MODE. The phone seems to be unlocked according to that screen but the FRP is loocked.
Things i've tried so far
Installed ADB latest version, extracted Recovery Cust System and Boot images from an official stock ROM.
Tried all available drivers from Google TP_Link and Intel for my phone.
The screen i am stuck does not work with ADB commands, the device is not recognized.
Fastboot commands work and it sees the device correctly, the problem is every time i try to flash the images from the stock rom i get FAILED message due to FRP Lock.
Format userdata and cache doesn't work either.
Vol + / - and Power button combinations also have no effect, it only shows that screen regardless of what i press.
I've searched the web and the XDA forums extensively since this happened and tried every possible solution i could find even if it was meant for another device.. no luck.
And here's my question, how can i possibly remove the FRP lock by only using fastboot?
Please somebody help, i am like half a day away from decorating the wall with this piece of ****
PS: I am not able to upload screenshots, sorry about that.

I'm stuck with this problem too. The exact problem. Have you found a way to fix it?
I have exactly the same problem with my Huawei Tablet.
If I boot with the original ROM and look in the "/log" - directory with adb shell, there is a cust.log. The contents say, that the specific ROM is not original or factory.
I think even the bootloader is unlocked, there is a kind of signature checking.
EDIT: @Asdforcer: Have you tried to boot the original boot.rom with "fastboot boot" - command?

Try to unlock your bootloader
Hello, i want to share my experience because it may me useful for others. I have also a question for you at the end of the story.
I rooted my MI A3 with magisk but without twrp back in 2019 following the guide posted on this forum. The phone had android 9 and I never did software updates. Once in a while a messagge appeared on the screen saying that my software was obsolete and that I needed to update but I always managed to dodge it.
Some days ago my phone started behaving strangly (eg: I turned the volume down to zero but it turned up by itself) so I decided to reboot it. Something went wrong and the phone rebooted in fastboot mode. I tried many things but the phone was only able to boot in fastboot mode.
I thought that maybe the problem was related to the software update that sometimes was popping on the screen. So, i connected the phone to my pc and executed some fastboot commands:
fastboot getvar current-slot (to know which partition was in use. It was B)
fastboot set_active A (to switch to the other partition)
fastboot reboot
The phone rebooted correctly but it was on android 10 (before the problem it was on android 9) and without root. Everything seemed working fine and all the data was safe (only one thing changed, the boot process require much more time now). So, I realized that the phone applied the system update by itself (without my consent).
Now my question. The phone works well for the moment but how can i check the status of the partition B? I suspect that it may be damaged.
Furthermore I would like to flash the stock firmware, clear all the data and unroot the phone. Can I proceed? Should I flash both partitions?
Thanks
Any suggestions?
