Is relocking bootloader possible for H990DS - LG V20 Questions & Answers

I have been thinking about rooting my v20(H990DS) and I was wondering if there is way to relock the bootloader afterwards in order to receive the oreo update (if ever released). Also after relocking will I still have warranty or not? I will probably use Dirty Santas guide for rooting.

Any help?

Yes you can relock your bootloader, however, unless you want to lose root, that isn't how you would want to upgrade to Oreo if you want to keep root.
LG phones don't have a knox style indicator to show if (or how many times) the bootloader has been unlocked. I have sent various V20 phones to LG for warranty repair after I bricked them trying to root them -- take that however you like.

LG G2 : Unlock the Bootloader?

Hi guys!
So, first, I don't create this thread to explain you how to unlock bootloader, for now, it's impossible, but, today, I was on @somboons' facebook page, and I see that LG G4 has an unlockable bootloader (LINK), so, my question to developers: is there any way(s) to unlock LG G2's bootloader by applying G4's method (or a close method of this one)?
(I don't know if my thread is in the right section...?)
Nope. As you need to be registered as LG developer first and then you need to choose the device you have and copy your imei and device id. I suppose that if the imei and the phone which you choosed doesn't match it will fail guarantee. So for now as far as I know it's not possible. I also suggest waiting for it as LG would soon add also unlock method for other LG device downside of this method is that there is no way back. Once you unlocked it you can't unlock it back and your warranty will be gone. So even if the G2 unlock method is out I still suggest to wait as some dev might come up by identifying the unlock method a way to unlock the G2 without registering your phone to LG and be able to lock it back
Hope to see LG G2 with unlocked bootloader as soon as possible..

[PSA] Read before relocking your bootloader

I'm not sure what is up, this isn't a new thing, but people keep coming to me (1-2 a day) with this issue.
If your phone isn't stock, DO NOT RELOCK your bootloader. You will 'soft brick' it, and at this time there is no easy route to fixing it.
If you are on EE UK, Verizon or another carrier blocking bootloader unlocks, and you used dePixel8 to unlock it, DO NOT relock your bootloader unless you are sure you don't want it unlocked again.
Finally, dePixel8 is UNSUPPORTED. Don't come to me if you can't get it to work, don't come to me if you used it them messed up your phone by flashing something bad or whatever. Its on you.
Great announcement. With the monthly security update out today, it is recommended that you don't install the update or have automatic updates enabled.

Huawei Nova "rollback" to standard Rom / unroot

Hi guys,
I'm thinking about rooting my Nova. But I'm new to the Huawei brand. (used HTC before)
I know, if I would root it, my warranty would be lost.
Is it possible to root it, flash TWRP and unroot also delete TWRP it if there appears hardware defects and I have to send it back to the factory? Will they know (like a flash counter in Samsung)?
Thanks in advance.
Well, if you flash full update.app it will wipe all and relock bootloader. So, no root and bootloader locked. There is no counter. This does depend on what kind of hardware defect of course, some types may prevent you from flashing the update.app. I am not really sure how strict Huawei is about denying warranty on modified devices. My friend took his (huawei but not nova) into a service center because his screen suddenly died. It was rooted, bootloader unlocked, etc. They did not bother checking all that, just confirmed screen was not working and replaced it for free. This was in China though, and here rules are often seen as suggestions, so results probably vary by location
in the read me of when installing nougat,it says that we can roll back to the previous version (mm)...thing is,in settings/fastboot,its not mentioned/available anywhere ,,,i mean the option to roll back
the text is also available in firmware finder under whats new (for the selected firmware)...

Google Unlocked Pixel 3a on Verizon

Hi all. I have been searching high and low for information on this specific question:
Will activating an unlocked Pixel 3a on Verizon disable the OEM Unlock and bootloader unlock capability?
I got a Verizon variant before I realized that there was not way to unlock the bootloader. Bummer. So, I returned it for an Unlocked version from Google, which I just received tonight. I breezed through the setup (without the SIM card) and noticed that OEM Unlock was disabled stating I needed to connect to the internet. So, I enabled WiFi and the OEM Unlock was then available. It would seem that I an now able to follow the unlocking procedure.
My goal is to unlock the bootloader and root, but do I have to do it immediately? My concern is that activating the phone with my Verizon SIM could:
1) Prevent unlocking the bootloader in the future if I don't unlock it before I activate with SIM (research seems to indicate that factory resets will undo disabling OEM Unlock if this can happen if I understand correctly)
2) Re-lock an unlocked bootloader - maybe this is not even possible?
I don't want to mess this up. All the info I am finding are discussions related to trying to unlock a Verizon variant and I cannot find good info on what happens to bootloader unlocking options on unlocked phones that are activated on Verizon. The only reason I may want to delay this process is because I dont have a lot of time at the moment and would rather not rush the bootloader unlock and root process. However, my HTC 10 is in bad shape and need a phone to get through the holidays. I was hoping that I could activate it on Verizon now, use it with its locked bootloader for a few weeks, and when things cool down after the holidays, implement the bootloader unlock and root.
If that is not advisable, what about unlocking the bootloader immediately (doesn't seem too hard and I have used ADB before), and activating without root. Then root later? Any possibility of concern #2?
Can OTA's re-lock a bootloader and prevent future unlocking?
I appreciate anyone's incite, experience, or links to the needed information for clearing this up. Thanks you!
I would advise you to unlock the bootloader asap. If you wait it will be a pain later because unlocking causes loss of data. If you don't care about that, wait as long as you like.
As far as Verizon is concerned, if the phone is unlocked, I don't see how they could possibly lock the bootloader. They may restrict your services but they can't touch the lock status of a device you purchased.

Re-lock bootloader

I have a TMO long ago converted to OOS & rooted. I'm trading it in & concerned Oneplus will reject it with an unlocked bootloader. My research suggests that it must be returned to full stock before re-locking. Does this mean just unrooting or do I have to return it to TMO stock. first?
