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.

Hello everyone, I was in China recently, and bought my OPO there. Therefore, it came with colorOS.
I wanted to change it to the rom to SlimSaber. Unfortunately, I've been unable to do so.
To unlock the bootloader I'm using this set of instructions:
[GUIDE] OnePlus One - How to Unlock Bootloader, Install Custom Recovery and Root - http://forum.xda-developers.com/showthread.php?t=2788632
I think my problem is while unlocking the bootloader. I get into fastboot mode, and using the android-sdk devices I'm able to get the serial number of the phone.
But, when I run the fastboot OEM unlock, nothing happens. Everything should be erased, right? Well, that doesn't happen. After that, I enable the USB debugging, but after, when I'm supposed to disable the 'Updater recovery with system updates' I simply don't see that option.
Can anyone help me? Do you need any more info?
Tanks in advance;

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.
Hi,
My phone went into a boot loop.
I can access the fastboot menu but the device is locked, I obviously now cannot enter developer options to unlock it
When means I can't unlock the bootloader, and without unlocking the bootloader I can't reflash the device. Bit of a loop of death
Any suggestions or is it a door wedge?

Hello and welcome to XDA-developers!
You can follow this guide to flash stock firmware through fastboot. If you have any doudts just report!
Hi guys,
im looking forward to unlock the bootloader on my Cubot P30.
The phone is responding in USB debugging moder over the shell, for example when I´m typing "adb devices" or "fastboot reboot bootloader".
But in fastboot afer restart the device unfortunately doesn´t respond.
I even dont really know if the Bootloader is locked or not. The OEM Unlock slider under developer settings is set.
Furthermore The Recovery menu is in chinese, so i also dont know if there is a chance to doublecheck.
I tried flashing an Image over the Shell in case the booloader is unlocked but without success.
Also I cant´t find TWRP for this device, it seems there is no support for Cubot P30, isn´t it.
Hope there is a chance to update the device to Android 10 or Lineage, thanks in advance.
Update: The device is now unlocked. I flashed the Lineage 17.1 and unfortunately the device is still rebooting. Has somone a working image for this device?
Hello, how do you unlock your phone?
Mine Is P40 and same issue.
So if you tell me the way i really appriciate.
Thank you.

Hey there,
I have a Pixel 3a, which refuses to start. After powering on, it directly hangs on the first google logo forever.
The device has stock rom and a locked bootloader.
I can still enter fastboot, but when I try to enter recovery mode from there I'm stuck at the google logo again.
Is there anything left I can do to revive the device?
- I cannot unlock the bootloader, because I need to the check this oem unlock setting which in turn is not possible whithout a working device. Or is there a different way?
- I cannot switch the A/B slot because the device is locked.
- I cannot flash something because the device is locked.
I'm grateful for any advice.

Hi there.
A couple of questions first:
Does it respond to any adb or fastboot commands?
Does it enter into Recovery or Rescue mode from Fastboot?
If yes, then your best bet is either https://pixelrepair.withgoogle.com/ or https://flash.android.com/
Both tools should work even with a locked bootloader, you just need Chrome and the USB driver.
Be warned tho, both tools will erase and factory reset your phone.
