H811/H810/F500?!.. imei 0, secure bootload errrrr

I bought a functioning g4.
Sticker on phone under battery says H811 with valid imei number.
Rom on phone is H810 variant, Android 5, and imei is 0.:cyclops:
Rooted.
Phone is working 4G LTE.
It will not do software update.
I'd like to flash twrp and a custom rom or even stock and revalidate it's imei.
I can turn on USB debugging but OEM unlock is 'twitchy' - If I 'agree' it goes off, if I 'cancel' it stays on (blue tick) until I tap anything on screen.
So far I have tried through TWRP app but I get a secure bootloader error and then normal restart.
I have tried a stock .kdz for H811 through LGUP but get an invalid .kdz file error.
How can I confirm if it is a H810 or a H811?
Please advise on way forward>>

only way to know and get it right its to open the phone and check the motherboard. see what it says h810 or h811 then proceed from there.. you got yourself a frankenphone... search for video on how to open..
Thanks for reply.
I am now considering it to be a F500L! Atleast the motherboard..
This because both the H810 and the H811 kdzs I have tried to LGUP say invalid kdz &, the download mode screen on my G4 is in Korean and mentions some 'F500 L v11d something..'
Clearly it is a refurbished G4.
Great phone..but I am so bothered.
Will I ever be able to run a custom OS and have a sensible IMEI on this phone?
I just tried to LGUP a F500 .tot and that too LGUP says invalid .tot..

Help ! Imei and Serial number corrupted G620S-L01

Hello everyone
I don't know if this is the right place to post it but I have a problem with my Huawei G620S-L01
I got it from a friend with Stock Rom 4.4.4. Everything was fine for 2 months until it starts bootlooping. I never tried to root this or something like that... After googling a bit, I found the solution to the bootloop in flashing Stock Rom via Sdcard/dload method. Everything was fine again... Then I noticed that the Lineage 14 (7.1.2) was out and I wanted to get it. But in order to flash it, I had to unlock the bootloader and flash a custom recovery. It wasn't a problem for me since I've already done it with other phones. The problem was to get the bootloader code from Huawei because I noticed that my IMEI changed and my Serial Number changed and shrinked ..... so I used those who are on the battery to obtain a bootloader code from Huawei (because the corrupted ones doesn't exist in the IMEI database even if they seems to be real). I thought that will finally work.... But no, the fastboot command to unlock the bootloader says : FAILED (remote: invalid key, unlock fail)...
So this is where I'm stucked. What should I do ? Did I flash the wrong firmware at the first time even if it seems to work like a charm?How can I get my IMEI and S/N back ? Does flashing another stock firmware will help me? please help me :crying:
I'm still unrooted
Thanks in advance
Please help me ! Anyone... :crying:
It seems that there is no solution...

ASUS ROG Phone 2 Tencent Edition Query

I don't know where to post my question so I tried it here.
I wanted my phone to be able to do updates manually via the firmwares in the ASUS Official Website so I tried to install their official app to unlock the bootloader because my SKU version is CN and I wanted it to be WW. It produces something like network error and saw that my SN is C4ATAS000000 and not my original SN so I've tried to do EDL Mode and successfully unlock the bootloader for rooting, the reason is I want to change the /vendor/factory/COUNTRY file from CN -> WW but when I'm in here I only see folders even if I tried using other apps. So sorry if what I'm saying is messy.
I need help with my phone, can anyone assist me? I've read something about as to why I don't have a COUNTRY file in /vendor/factory is about persist.img, I'm scared to do something without guidance because I'm afraid I'll just mess my phone.
Here is an image for reference about my phone's current info.

Restore Phone Serial Number to its original SN.
Please assist me in restoring my Serial Number to its original SN. T.T
