I have a Nokia 6.1 2018 PL2 and I'm trying to unlock the bootloader using the "Nokia bootloader unlock tool" by "techmesto".
The problem is that the device serial number shows as "??????????? fastboot" when issuing the "fastboot devices" command , so when providing the OTP code for the tool and the tool begins flash I encounter this error "Error: Serial number is empty or invalid!". What could be the problem? any help would be appreciated .

Hi,
Why you use Nokia tool for Xiaomi/Poco device? That doesn't make any sense, it will lead to softbrick/hardbrick.
Please check my guides at POCO F1 Ultimate Collection & Guides. (Guides are on post #2 there).
Edit: Seems you confused the threads/devices. If you have poco f1 check my guide tho.
Because I have both phones at now, I messed up the thread at first and then corrected the confusion, my bad. The thread actually was about the Nokia phone not the Poco one, but anyway I'm gonna take a look at your guides , I'm sure they're gonna be of great help for me because I also have the Poco phone until I get a solution for my Nokia phone problem.

Hi guys. There seems to be no thread for Galaxy J4 despite requests to put it up so my sincere apologies if I've missed it. Got my sister's J4 on FRP lock. She hadn't enabled USB debugging nor OEM unlock in Developer options. I've watched tons of tutorials on how to unlock but it's dawned on me that none of these methods can work with the bootloader locked. The only way I think I can do that is by flashing the exact combination firmware then enabling USB debugging and OEM unlock then attempting FRP unlock. Problem is, the available combination firmware I've come across are binary versions U1 to U7. This phone is binary version U9. I've scoured the internet for this specific combination firmware to no avail. Anyone knows where I can find it? It's been a long 3 months of searching am almost giving up.

Thanks for that. An oversight on my part.. Will adhere to the guides.
This is a very simple question, and i have tried scouring the internet for this answer, but to no avail, i havent found anything. Has anyone successfully unlocked the bootloader/rooted/and flash an american OS to the Vivo X Note? I've tried all the conventional ways to unlock the bootloader on this device and nothing works. It's so odd because vivo has OEM unlocking in the dev options, but nothing in ADB works with it and there isnt an OEM tool like Xiaomi's tool that can do it. Every command just does not work with this phone. I hope there is an answer out there cause i would love to be able to remove originOS and put funtouch or something American on it. Thanks!
have you tried below command from fastboot-
fastboot bbk vivo_bsp unlock_vivo

I know this was quite awhile ago but I can help if you're still interested. This is my current device and I have a pretty good handle on downgrading/rooting. I can also help you get back to the latest OTA. The key is to make sure you have a copy of the OTA.zip or at least the boot.img from that OTA version. I have all of these files backed up and can share them but could also walk you through the process so you're able to do it yourself. Let me know if interested. If there is a demand I may write up a guide. Happy to share any knowledge/data on an individual basis if not

If you're asking whether the bootloader can be automatically or inadvertently locked, the answer is no.
Unlocking and locking the bootloader are intended to be deliberate acts requiring specific commands. Once your bootloader is unlocked, the only way you can lock it is by using fastboot commands, the same way you unlocked it.
Keep in mind that if the software on your device is not absolutely 100% genuine OEM, locking the bootloader will most likely render the device unusable.

depending on your device, you do not need unlock service, use hardware testpoint (requires dissassembly the phone)
the software you can use is potatonv
hi, i have a realme c21 , but it has a problem, after 1 year of realme UI 2 without updates (because i never got the realme UI 3) i got tired of the usual interface, so i would like to install a rom, the pixel experience, but the problem is that the bootloader does not unlock, because when I restart it from ADB sideload in fastboot, the phone restarts in the normal way, without going to fasboot, and for a second you see a message that seems to me to be: emiei does not match
reboot_bootloader_faild. i searched for a long time and i found nothing, even trying to downgrade from android 11 to android 10 it doesn't work, because when i install the OTA update at an installation point it says "FAILD TO INSTALL OTA UPDATE", the '' realme unlock doesn't work, because it says that my devices are not supported, could anyone help me?

Oh scusa Ah sorry I'm new, and didn't know about it, so is everything okay now?
I recently received my unlock token and like some knucklehead downloaded and flashed my holi version with the Dre8 img and now I have a brick could some one that has the holi version please run this command in their adb if their bootloader is unlocked and post it please I'm begging you
adb pull /sdcard/*.img/vendor/firmware/
I have zero idea what you have written like what holi version and what not but this should solve your problem
flash this - https://firmwarefile.com/oneplus-nord-2-5g
Also do not flash other nord 2 firmware preloaders from that website as that would result in a hard brick and you would be forced to go to the svc if you want to revive your phone ( for now ) .
Also what is an unlock token for nord 2 ? i think you might be in the wrong forum because there exists no such thing as token for nord 2, feel free to correct me if i am wrong.
