HELP unlock Bootloader failed remote.

Hello to all guys, i have a mate 7 gold rebuilt, then, this happens
I tried the huawei site to do the unlocking procedure, I compile everything, but I do not accept imei, always tell me to put imei valid, it's a dual sim, i put 2 but nothing .... in fastboot mode, my phone From the phone unlocked, it seems that the bootloader has already been unlocked at this point, but if I try to drop a command, I have always FAILED REMOTE COMMAND, as if it was blocked.
I tried to make a check, and I was unlocked, so the bbotloader seems to be unlocked.
Now the phone is brilliant, does not go into recovery, what can i do in rescue mode does not restore it ..... thanks for the attention.

I dont know what happened. its not turning ON.

flash mode and fastboot mode is detected by the pc.
I have tried alot of tutorials. first i tried xperia companion. when tried to repair software it says NO UPDATE FOUND FOR YOUR DEVICE Bla bla.... (screenshot attached).
Then I tried Emma. it says a locked device detected with imei number 00000000000000. (screenshot attached). dont have original IMEI because it was a used device.
then I tried flashtool to unlock bootloader and to flash ftf file. got unlock key for null imei which is 758E6C504FB2D439. tried to unlock bootloader with the key but it was failed. logs are attached in form of screenshot.

Your device is a prototype and will not boot retail firmwares. To have it working you have to unpack boot img and edit default.prop to add/modify "ro.build.type=eng". Use my released boot to do it or you will have to build the kernel and remove dm-verity yourself. You need an unlocked bootloader but prototypes should have it "out of the box". The bad thing with that kind of devices is that they are collecting data to Sony so be careful if you use it for daily.

First of all you must be sure that your bootloader is unlocked, you can check by doing this: put the phone in fastboot mode and try to enter the command "fastboot oem unlock" without quotes. It must return an error with (not necessary) at the end. If the bootloader is locked you can find the original IMEI by removing microSD and SIM tray then pull the small strip in the slot, the IMEI is written on it.

You mean to say that imei number should be written on sim tray?
I removed it but it was completely blank....
and also checked for a hidden plastic strip inside the sim slot and memory card slot as well... but found nothing.
Any other way to find????

[Need Help] Is there any way to unlock my phone without losing any data?

I'm using samsung galaxy A51 global version.
Recently, I changed my lock screen pin code at night and never tried to unlock with the pin until the pin code is required instead fingerprint.
So, when I tried to unlock with the pin code , it says the pin is incorrect. I tried pin several times but failed and it's time blocked and there is no option to reset password like older versions of samsung phones.
I have so many personal data in my phone, so I need to unlock my phone somehow. Please, help me if there is any way to unlock the phone without losing the internal memory data.
hello good, enter your Gmail account, from there you can change the password.

Hi, Its only possible if u already had twrp installed, in that case enter the twrp file manager and delete the following:
/data/system/locksettings.db
/data/system/locksettings.db-shm
/data/system/locksettings.db-wal
you can enter google from a computer, enter search and change password
