hi all
is there any way to bypass p8 bootloader to flash boot , recovery without unlock it
cause i lost my sn and i cant unlock bootloader official way ?
No.
Hello, you can't bypass the boot loader but if you can boot in Fastboot mode and Run ADB you can get the serial number
Hello.
Long story short:
I have a OnePlus2, I can boot in Fastboot mode and my PC does recignize the fastboot device.
fastboot oem device-info says that Bootloader is locked and when I try to unlock (fastboot oem unlock) it states "okay" but cannot boot into system because there is none installed. -> Bootloop
I cannot boot into recovery nor install a recovery due to the locked bootloader.
My Question:
Is there a way to unlock the bootloader in fastboot and/or install a boot.img?
I am happy for any help that I get.
Have a good day/night

No, but why you don't have system?
You have stock recovery download official signed full zip and flash it. Recovery.
Also unbrick guide using the one you need Qualcomm drivers

Hi.
I´ve unlocked the bootloader on my P10 plus.
But now, the toggle to unlock OEM on the developer settings is greyed and I can´t perform any fastboot commands.
Any help?
Thanks
I believe the option becomes disabled when you've unlocked the bootloader, as you'd have to use the relock command instead of the toggle to relock it.
I assume you're familiar with accessing and using fastboot if you've unlocked your bootloader... so for the fastboot commands, does the device show up when plugged in and you run "fastboot devices"?

i have my huawei p10 plus doing the same thing of yours.....only erecovery mode and when i get to boot in fastboot mode is only fatboot mode & rescue and i had locked bootloader and frp lock.....but i was reading that huawei just block the page to unlock bootloader i just dont know why they did that /......
Maybe try re-unlocking and flashing stock rom, kernel, system, and boot. (Or you can try the method I used to update manually). Requires to be able to acces external sd card.
Hmu if you want to know how.
Hi could I ask because i lock my bootloader on Mi A1 but unfortunately the device didn't boot up.
Now, I am trying to unlock bootloader to fix my device and it won't unlock FAILED (remote: oem unlock is not allowed).
I am on May latest security patch build. Please help me.
Did you try reflashing ROM with Mi Flash tool? Use "Save user data" option there.

I think you tried to lock your phone after rooting your device. You'll have to try to switch to fastboot mode by volume down + power after vibration. Then use flash using Mi flash tool
I cannot do that, the bootloader is locked and I am on May security patched. Those fastbook oem unlock and fastboot flashing unlock methods won't work. I believe only testpoint is the solution to my problem.
Stuck with the exact same problem....did u find the solution

Reboot to fastboot power+volume down then reboot to edl mode by typing "fastboot oem edl" in your adb your phone will turn black. Open miflash and click "refresh" if you see "com#X" it means its connected then flash the fasboot file you downloaded in mi forums after finish press and hold power until it restarts.
Hi everyone,
I am the owner of an A2017G, unlocked bootloader.
I tried them all, but all of them and I can't get into fastboot / bootloader mode.
Ihave flash rom via MIFLASH and AXON7 EDL TOOL using rom Nougat and Oreo, but the result is always the same !!!
Do you have any ideas to help me, perpetuate?
Thank you.
Use miflash and flash unlock bootloader image by Turkdev, even in oreo it will give you fastboot menu.
I did this 3 days ago to relock my bootloader
Use this tutorial:
https://forum.xda-developers.com/axon-7/how-to/guide-unlock-bootloader-easily-t3704595
The reason you lose your fastboot menu because you unlock BL with another image (using Axon 7 EDL tool perhaps), but if you do unlock with turkdev image in tutorial, your fastboot menu will stay there
