Hi!
Nexus 5 16Gb, lot of acore and gapps errors when boot, then cyclical reboot. When i try unlock bootloader with fastboot mode, it shows UNLOCKED, but has status LOCKED again when reboot.
Any ideas, please
TIA
backup your apps/data, do a factory reset, flash your favorite ROM.
most likely you are having issues because of dirty flashed several incompatible ROMs

Factory reset was done, can't flash ROM because bootloader won't stay unlocked when i unlock it thru fastboot!
If the bootloader can't be unlocked, you can't do anything other than factory reset. The fact that the bootloader is locked even after unlocking points to a hardware issue.
BTW, After doing fastboot oem unlock did you select "YES" on the onscreen window which pops up?

Sure i did this
and then "fastboot reboot"
I'm not 100% sure it's possible, but can you re-flash/update bootloader?
because i think all cyanogen nightly builds after 03/17 require the latest bootloader.
Have you tried formatting? If you're not comfortable with it, don't try it, but it's certainly a step up from a factory reset. I'd bet it's just artifacts, as mentioned earlier.
I did factory reset many times (from recovery), but i can't unlock bootloader : when phone reboot after "fastboot oem unlock" command - bootloader is locked again
Not being able to unlock your bootloader is a good indication of emmc falling. You're most likely going to have to rma your device.

So I unlocked bootloader then reboot to boot-loader, now on fast-boot mode, trying to install twrp and it says FRP lock, and cannot execute any commands.
I know my passwords etc but doesn't work, anyone with ideas?

Seems like very old build. But no update for L09C185.
You should request update from Huawei Support.

Funny thing is that I can use the phone etc but cannot execute any commands on bootloader.
When I dial *#*#2846579#*#* then select reset, it is clean of any FRP! It's only when it's in fastboot mode!

This FRP Lock is different from the Google Account one, this is at the Bootloader/Fastboot screen. Logging in etc is working.

Disable oem unlock in dev options and enable again.
Try factory reset from stock recovery.
Unlock bootloader again.

You basically have to reflash a Rom again with funkyhuawei which will relock and fix your ftp lock in the bootloader. Had the same problem and took me a while to recover...
Second time you unlock the bootloader after fixing it this way it works properly. At that point I just said screw it and left it locked. No idea why, must be some kind of bug.
I unlock the bootloader to install twrp and magisk, it's possible to lock the bootloader again without problems or the phone don't boot?

Locking you bootloader while TWRP and Magisk are installed will give you a guaranteed brick. Use a Fastboot Rom to return to stock, then you can lock it
If you want to keep TWRP and root, do not lock the bootloader. As the user mentioned above, you'll brick your device.
if i flash stock rom, than is that ok to lock the bootloader ? and how to lock it ?

If you flash a full stock rom then yes. All you do is use the fastboot rom we talked about earlier, let the phone boot up (don't bother completing the setup process, just let the phone boot up), restart to bootloader, and use the following command from the command prompt on your pc:
Fastboot oem lock
It will give you a menu on your pone asking if you want to lock the bootloader. Tell it yes. It will then lock the bootloader, factory reset the phone, and then boot up normally with the bootloader locked. It's that easy.
ok thanks.one question. is that important to flash the stock rom using fastboot only ? or can i flash it using twrp ?

I did it through twrp, worked just fine. Make sure to wipe beforehand though, don't want to risk bricking your phone

Doing it with a Fastboot Rom will guarantee that things needing wiped will get wiped. When returning to full stock I will always recommend the Fastboot Rom just because of how it completely handles everything it does flawlessly. I imagine flashing a full rom in TWRP will work but I have never tried to return to stock this way
i did try stock using twrp and it was perfect
I have unlocked bootloader but in the end NOT installed TWRP or root (just wanted to test if i can live without it and still be able to install without wiping everything)
Now I just want to lock bootloader again for selling device.
Can I do so with simple fastboot command "fastboot oem lock" without bricking phone?

Use msm download tool to be sure. It will however wipe all.

You can, but if you are selling the phone I would still use a fastboot rom just to be sure everything is wiped and no data sensitive to you is being sold along with the phone.
Thanks a lot for the shared info here. This is just what I need and had been asking myself for quite some time now.??
So never lock bootloader with twrp and magisk installed.
Hi everybody!
After the precious advice of user ndt192, I managed to unlock my SKR-A0 which, until this day, seemed un-unlockable.
THIS PROCEDURE WILL WIPE YOUR PHONE MEMORY SO REMEMBER TO BACKUP EVERYTHING
TL;DR
In developer options, OEM Unlocking must be ticked (if present), then I just issued a fastboot oem unlock while in fastboot mode.
I'm on the latest OTA (29-12-18, v. G66X1812291CN00MPX).
Full Tutorial
Enable developer options by tapping 7+ times on Settings -> About Phone -> Build Number
Enable USB Debugging and OEM Unlocking (if present) in Developer Options (Settings -> Other Settings -> Advanced Settings -> Developer Options)
Open a terminal and issue the command adb devices
On the phone, allow the access from your computer on the dialog that will be shown
In terminal adb reboot bootloader
Wait for the phone to reboot in bootloader mode
STOP AND THINK - DID YOU BACKUP EVERYTHING?
Issue the command fastboot oem unlock and wait for the OKAY in the terminal window
Reboot your phone with fastboot reboot
Now, you will be informed that because of the unlocking your phone memory is "corrupted" (aka not decryptable anymore) so the phone needs to be wiped. Agree and wait.
Hopefully, your bootloader will be unlocked now. You can check that by returning to fastboot mode and checking that the Status is Unlocked.
If you want TWRP/root, check out this thread.
This procedure didn't seem to work until a few months ago so I don't know exactly if this procedure works only on newest Joy UI versions or not. Try it out (at your own risk).
IMPORTANT - if you can't unlock with these steps, please post here with the version of Joy UI installed and the message shown after the fastboot oem unlock command

Hey what's up.
Having issues and want to start from scratch but the MSM download tool isn't working for me due to driver issues I can't seem to resolve.
I'm unlocked and rooted with a custom kernel but otherwise totally stock.
Would I be able to just fastboot flash the stock boot.img and relock the bootloader for a total data wipe? Would that be enough to start fresh?
Go into magisk. Click uninstall. Click restore images. Your images should have been backup by the app. Reboot and reset from reset option in phone. No need to relock.
Thanks. Is that as good as the MSM tool as data wipes go? Want to get as fresh as I possibly can without MSM...

You can't lock the bootloader while rooted. Your patched boot fails startup checks. The only phone i remember that you could root and relock was the oneplus one. There was a software hack to do a soft bootloader lock/unlock without wiping the data.
To expand on that, if you modified any locked partitions and try to relock the bootloader, you'll essentially soft brick. The only thing you can modify is I believe is userdata. If you are unsure, why take the chance, especially since your MSM isn't working.
Just do a factory reset from recovery lol or use fastboot
