(URGENT) Bootloader Got locked after flashing official Lineage OS 14.1 - LineageOS Questions & Answers

Hi,
After running out of patience i unlocked boot loader on my RN 3 unofficially (SD VERSION), and flashed lineage OS, but i did not get VOLTE on it.
To fix that i flashed CM Firmware and VOLTE patch files (Still no VOLTE, ONLY LTE, then i rebooted to the phone, and now the bootloader has locked automatically.
I am able to root into TWRP, but not into EDL. I have an MIUI backup that i took, now that the bootloader is locked, will i be able to restore the backup through TWRP. There is an update of Lineage OS of 19th april, when i click on install it says the phone will reboot to recovery to install, my question is will the update be installed or not since the bootloader is locked, or if i install the update the phone might go into bootloop?? i don't want to take a risk.
Please help me if i should install the updates and whether it is possible to restore backup when the bootloader is locked.
Also, what should be done to get VOLTE Working on the existing ROM, i flashed CM firmware and Volte patch from the link (https://forum.xda-developers.com/re...t/volte-patches-nougat-based-cm-roms-t3509257)
Thank you

RQ: Links to Root Tutorial

Hello,
I am currently downloading 7.2.16 (MIUI8) Developer Rom for my Mi Max, so i could unlock its bootloader since i got the permissions to do so. I have a few questions for the time after i unlock the bootloader evenyually:
1. Can i go back to the latest stable global rom and still have my bootloader unlocked?
2. Can you give me a link to suitable TWRP/Root tutorial.
3. If i succeed with the flash of TWRP and Root, would i be still able to receive OTA updates.

Hello, this is the best guide to root your device, also if u go back to another rom then yes the BL it will be unlocked. I think that you wont recieving OTA updates. but like i done before, u can download the rom that you want and flash through the updater app from settings
Please, before you continue download the last version of the TWRP, the newiest ( https://dl.twrp.me/hydrogen/ )- SO use the new image.

OTA Update without data loss from 5.0.2 to 5.0.3 and Unlocked Bootloader

I have an important question.
I'm currently in stock 5.0.2, with unlocked bootloader, no custom recovery, and no root.
Now I'm getting this screen in the Update menĂº: "OEM unlock is detected, system will begin downloading the full upgrade package. To ensure your data integrity please perform a backup" (see attached image).
Can anybody confirm if it is safe to update (from 5.0.2 to 5.0.3, in my case) with an unlocked bootloader (with stock recovery, and no root)?
I read in some post of OP5 forums (not 5T) that upgrading from Nougat to Oreo with an open bootloader could result in a bootloop, forcing to "wipe data" for getting the device to boot, and hence losing all data... I know that if I lock the bootloader again, it will wipe my data, and I don't want to.
I also know that a modified system (with custom recovery or root) could result in a bootloop after update, but I want to emphasize that my OP5T has just an unlocked bootloader, but it has stock recovery and it is not rooted.
So, is it possible to update to 5.0.3 with an unlocked bootloader (stock recovery, no root) without any issues or data loss?
The strangest thing is that I hadn't any warning like that when I upgraded from 4.7.6 (Nougat) to 5.0.2 (Oreo)...
Thanks in advance.
I upgraded my phone with a custom recovery installed and had no issues at all, so having the OEM recovery shouldn't give you trouble at all.
The warning is there because 1+ is probably aware that people who unlock their bootloaders do so in order to install custom ROM's and kernels and hence they need a custom recovery installed. That's probably why it downloaded the full size zip instead of the smaller OTA.

Well, thank you for your answer.
Finally, I did the update. It downloaded the full size zip (1.6 GB), and upgraded the device from 5.0.2 to 5.0.3 with no trouble at all. So, at least in my case, having an unlocked bootloader didn't make any problem to update my OP5T.

Update your firmware to an oreo firmware, simple as that. Oreo roms do not work on nougat firmwares
Perhaps

Thanks for the respond,
but for that I need root, which it is the problem with supersu.
I need root for Sunshine, so I can place oreo on the phone.
Do someone remember which version of Viper works with Nougat and if I need to have the phone root first before flashing the ROM.

Alright, i will ask this question.
Why do you need root? Why do you need s-off. Why can't you go back to stock and take the OTA to oreo first, hasn't t mobile released the oreo update yet?
Edit:
At least i found a ruu.exe here
https://androidfilehost.com/?fid=746010030569947237
Thanks to @ziand
That file will bring the phone to box stock and at that time you will be able to update to oreo.

lock bootloader oneplus 3

Hello
I've installed lineage 17.1, my recovery is TWRP 3.4.0, I also installed Magisk.
Every time I restart my Phone I'll get a warning screen that my bootloader is unlocked.
My question is: is it better to lock the bootloader again or let it unlocked?
If I lock bootloader, can I still update lineage en will I keep root from magisk?
Do I loose data?
You need to have an unlocked bootloader to use Custom ROM like Lineage OS with root by Magisk.

It is dangerous to lock the bootloader while having a custom ROM. You will lose the ability to flash zip files if something goes amiss. In addition, while locking the bootloader, you will lose all data.
If you are on OOS, then you can safely lock the bootloader.
Locking of bootloader will not affect the custom ROM already installed or root.

Upgrading to Android 10 on Redmi Note 8

Hello guys, I knew yesterday that Android 10 finally came out for Redmi Note 8, however for now the china version is the only one available, flashable via UPDATE.APP, right?
That's my question: I'm currently on stock Android 9, but with unlocked bootloader and root with MAGISK.
If I do the update to Android 10, will the bootloader be locked again? Will I be able to unlock again? And I guess I'll lose root too, will be possible to root with Magisk?
Thanks in advance

Just clean flash rom through recovery+flash magisk that's all. Backup everything before flashing. After flashing if reboot redirects to recovery then simply format data partition and reboot again.

i think you can not update this with update app, this update is only for beta tester
you can clean flash it with recovery, if you do this you lose everything along root, data, pictures etc
if you just want miui 12, you also can try eumiui 12 beta with Android 10 or wait for global stable
whatever you choose to do you can not lock your bootloader again even if you select it in mi flash tool you will just brick your device and, bricked device is bigger problem than locked bootloader
Wait for the official OTA update
