Hi, i have asus zenfone go and it was working fine for few months, then it started bootlooping, now it shows first image and shuts down.I can get in bootloader menu, but can't go to recovery, it just shuts down.I've tried using adb and fastboot, installed drivers, but adb doesn't detect it, fastboot dectects it, but I can't do anything without unlocked bootloader, but when I type fastboot oem unlock and confirm on phone it fails to unlock.If someone can help me please answer.

hello, I have tried to unlock bootloader through fastboot, but I don't have permission. I found sp flash tool which can flash rom, but I wasn't able load stock rom scatter, so I downloaded some system backup of same phone, I flashed it, now my phone doesn't show anything on screen, I can still connect it through download mode and when i just connect usb to pc it keeps restarting(pc makes connecting and disconnecting sounds).I read that it is because I of bad rom, so if someone has stock rom which can be loaded in sp flash tool I would be thankfull if he could give me the link.
Sorry for my bad english.

I have a Micromax A290 [Canvas Knight Cameo] which is rooted. I have installed adb and fastboot drivers in my PC running Windows 8.1. I am trying to unlock the bootloader of my device.
So I connect the device, type "adb reboot bootloader" and the phone boots into fastboot mode.
Next, I type "fastboot oem unlock" to unlock my bootloader.
The phone asks me for confirmation and I go for Yes.
Here is the problem.
After I choose yes, a message comes up in my device saying this:
"BOOTLOADER UNLOCK FAILED. RETURNING TO FASTBOOT IS 3s..."
I have tried everything I know. Used a different cable, used another port, but to no avail.
Please help me.
Thanks in advance.

I believe that relock is impossible and but to make the device recovery to installed status of stock rom keeping with unlock bootloader.
Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

Why you want to lock bootloader ? Install custom ROM is need unlock bootloader. Why you first unblock it and then block it. Officially rmx1971 can run until android 11, with custom ROM it can install new version. What you need do is. Go to bootloader download my TWRP if you are on Android 11 and flash it
Fastboot flash recovery recovery_3.6.2_11.img from there you have to install custom ROM.
Hi All,
I apologize if this is the wrong forum, or if this question has been asked elsewhere. I think my phablet no longer has a dedicated forum. I have a Phab Plus, PB1-770M that I'm trying to unlock the bootloader on. but I can't seem to get into bootloader mode. I can connect to the device with ADB, and I can run adb reboot recovery without issues, but when I try to adb reboot bootloader, it reboots and just hangs at the lenovo splash screen.
Is there anything I need to do first to get into bootloader? Is there any other way to unlock the bootloader?
I'm trying to put a more recent version of LineageOS on it, and I need to get the bootloader unlocked.
Thanks for any help,
Ivan

The bootloader mode doesn't actually have an interface, it's just a boot logo.
Use a computer and run "fastboot oem unlock", then flash a recovery to flash my ROMs.
