[Q] Unlock after Firmware upgrade

Do I have to unlock my device everytime I upgrade firmware or change ROM? I am playing around trying to find the ROM I like most. But don't want to Root, and unlock after.
unlike the iPhones, your i9000 will remain unlocked once you've unlocked it. Firmware upgrades are for legit reasons, not just to lock your phone down again.
Rooting is affected by firmware upgrades but is easy to fix.

If I make a nandroid of my current rom (Vodafone Spain stock Rom).. will this "save" the lock/unlock status, or is the status NOT depending on ROM?
I need to know this because of warranty .

[Q] Relock bootloader and then go back to v10f

I am trying to sell this phone. Because I dont want that somebody take this phone to service and that they discovers unlocked bootloader. Now, in locking-unlocking app it is said that I have to be on rooted v20 (4.1 android). Can I do that and with locked bootloader flash v10f that came originally with phone? Anybody knows?
Thats a good question. But I think there isnt a anser. Yes you can try to flash v10 so it wont show you that the bl is opend. The problem is, if you update to 4.1.2, you will be possible to detect the opend bootloader.

Relocking bootloader

Hello guys,
After i tried a few different roms around here, i came to the conclusion that stock rom works the best for me.
I managed to revert back to stock rom BUT, i am not able to lock the bootloader to its factory state.
Relocking the bootloader via fastboot won't get rid of the message screen that bootloader is unlocked during bootup.
If anyone knows how to get the device back to its original firmware state, please share it with me.
My device is : VTR-L09C432.
Thank you!

How to go back to stock and relock the Bootloader?

Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..
If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Hey I've tried this otg method but without success
If I try it with the dload folder option and try to force flash the emui updater throws an error.
Even with the dialer code method.. same..
I'm not able to get it to stock.
I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?
Current state, halfway working phone that's boot into os 2 times from 10 reboots.
