You had to dump your partitions before you unlocked bootloader

To unlock or relock? To unlock you don't need anything else as I can see as you're also on H815 EUR as me so you can unlock yours on LG website, if you mean relocking, yes you can, but I'm not sure if it will work on warranty as you will have partitions from other G4(other serial etc) unless no personal data is stored on those partitions

Oh... I mean go back to locked. It's already rooted since 9 month.
going back using my phoes's serial, data, etc... from my (rooted) partition, without need for any original (backupped) state.. possible ?

If those partitions doesn't contain your IMEI, serial etc then yes, I don't see any problem to get back to locked and get it on warranty repair. But if they contain(I think they do, as they generate your unlock.bin file), then most likely LG will put you in charge of repairs or deny to do anything with your phone

There is no tutorial at this moment - just wait, I need to do "some things" and check "some things" before release. Tutorial is not ready so dont try to use this method in video becouse you can hardbrick your phone...

Another hoax...
What does it mean? Video should be enough to prove that this method is working so please dont call my hard work "hoax"...

Nice ! Thanks .but i wait step by step instructions video very laggy :D:D:
Here you told something different. Dont change you're mind becouse you need to wait for detailed and working instruction. I can release instruction if you really want it, but it's not completed and many users of LG G4 may hard-brick their phones becouse of it. There are different methods for each phones - all are similar but not the same.

OP, you are silent about bootloader unlock. Please give me some information about that
Watch the vid in the OP. The variants are all different so the steps and partitions will be different. Just like flashing the wrong ROM for a different variant, it's not usually a good thing.
