I have a Magisk-rooted LG V35 running some uncertified custom ROM installed by former owner. I'm wondering if it is possible to flash an official stock ROM on the phone without losing root? My goal is maximum compatibility with standard functions (e.g. VoLTE, Google/Firebase Cloud Messaging, etc.) with root.
as long as you dont lock the bootloader, you can flash the stock firmware and then root the phone
even if you lock the bootloader, you can unlock it, but it's a bit harder

Do you want to bootloader and unlock and root your V35? Do you want to do this yourself? Are you feeling the need for some adventure? If you answered yes to these questions, then you are at the right place. The goal with these instructions is...

15=Bootloader That Can Be Unlocked And Custom TWRP Recovery Can Be Installed
11=Bootloader that CANNOT Be Unlocked. You can only have root through Lollipop 5.0 with SafeStrap Recovery or FlashFire. You can use Marshmallow ROMs but only non-rooted one, preferably with the use of SafeStrap. This Will Allow Easy downgrade to Lollipop to reroot and flashing of certain modified Marshmallow ROMs and mod zips
I am on OOS 4.5.13 "stock", i used the engineering mode exploit to get magisk root while my bootloader is still locked, now i want to upgrade to latest OOS oreo but i am afraid that this exploit might end up bricking the device. My bootloader is still locked and i have stock recovery (sorry if stating the obvious) and i have no problem losing my data to upgrade to oreo, but i would like to get magisk on oreo when i upgrade, any tips/precautions or a link to a guide would be very helpful. I don't need to root right away as i might like getting OTA updates but i don't wan't to wipe the device another time for some special procedure.
Should i unlock bootloader then upgrade or reverse the order? I keep getting these prompts to upgrade with a disclaimer that full system needs to be downloaded, should i just do it OTA?
PS: i have titanium backup working and can backup the apps i need.

if you are ok with loosing data then i suggest you to unlock the bootloader then flash the latest oos build from the official website ( that makes it easy for you to switch roms easily in the future )
if you need your data then just accept the ota ( obviously you will lose root access and magisk features )
but imo no harm can be done accepting the ota as oneplus itself know that most of users are rooted so they send you the ota as a full build that replace the firmware parts previously modified
the choice is yours

Flashing the custom rom with rooting the device make the device less secure and we cannot use the internet banking applications so , can we flash the custom rom without rooting the device ! If, yes then what will be the procedure !?

Jajajajajaja sorry but your question is very funny????
But no, it's not possible install custom ROM without root
I would think one can flash when booted into TWRP. One needs to be unlocked though.
The custom ROM you flash does not need to be rooted either.
In fact one can boot into TWRP from fastboot. So one does not even need TWRP on the device itself.
You do not need to root your device to use a custom ROM. But if you wanna flash GApps, then you need to root your device or it may not work as intended.
Wrong, Gapps can be installed from TWRP which has unlimited access to the system partition. In that sense, TWRP is "rooted". But this has nothing to do with the installed firmware being rooted or not.

Wow this thread exploded with mis-information.
You can install custom ROM's unto your device via TWRP, as well as flash GAPPS and any custom kernels, mods etc you'd like WITHOUT having to gain superuser access within the ROM itself.
You WILL however require to unlock your bootloader that, at least as far as I know, WILL trigger safety net and thus render certain applications (like said banking apps) unusable. To avoid this you can flash magisk, an alternative root solution that also masks certain aspects of the device that allows the device to pass safetynet while retaining root.
There are plentiful amounts of tutorials out pretty much everywhere that will allow you to easily unlock your bootloader, install twrp and root w/ magisk if desired, etc.

I don't think you can relock the bootloader when on a custom rom. This will probably brick your device since it will fail the checks of the locked bootloader and then you will have a bricked device with a locked bootloader.
So yeah, you also spread some misinformation I suppose which is even more dangerous than what the other users suggested.
+1, no way you can relock your bootloader after installing a custom firmware. Bootloop guaranteed.

Could have sworn you could do this but I guess I was wrong, sorry for that.
Edited original post.
If I end up with the 4/64 variant (then my 2/32 lives on as some backup device/wifi)...pretty sure it still will have stock Nougat. If I upgrade immediately to Oreo via OTA, can I still unlock the bootloader and root, or unlock it on Nougat and then upgrade via OTA and then root it?
Also, true I couldnt reflash a TWRP backup of a Pie ROM on my 2/32 and into a 4/64?

re lock ur bootloader back to stock then up grade to 8.1 if ur a senior member you should know that.2/32 4/64 are hardware in your phone .
Not exactly the answer I was looking for. The exact question is, unlock bootloader on Nougat or unlock after upgrading to Oreo? Or get the unlock code while on Nougat, upgrade to Oreo and then unlock and root?
If you're not currently bootloader unlocked, then you'd be best to take the OTA. After that, you can unlock the bootloader and root. If you're already unlocked, then you'd probably be better off just getting a TWRP flashable oreo build and just flash that. I wouldn't take a TWRP backup from one phone and restore it to another, since it might cause issues with things like serial numbers and IMEI. You'd be better making a backup with Lenovo Moto Smart Assistant or something similar. Just remember that unlocking the bootloader will wipe the phone. So if you re-lock it, or it's not currently locked, make the backup before doing that.
Update to Oreo with LMSA, unlock bootloader then root. Make backup before all. LMSA will prompt you to make back up, I think.
Hi guys, I have a LG G6 H870i (Brazilian version, but no carrier), and I've done everything to officially unlock the bootloader, but when I try to do that method on the LG website, it always says that the my device version is not available to receive bootloader unlock key.
My goal in unlocking the bootloader is to install root (I couldn't without unlocking despite having tried in several ways, including kingoroot) and also custom recovery TWRP (or any other), so that with them I can reach my purpose of installing a Custom Rom such as Lineage OS.
So, is there any way to unlock bootloader other than through LG's website?
If not, is there any way to install root even with the bootloader locked?
And finally, if none of these procedures are possible, is there any way to install twrp or any other custom recovery without needing either an unlocked bootloader or root?
Thank you for your attention.
The answer to all your questions is NO.
No, you cannot bypass the bootloader lock.
No, you'll need to exploit the android which isn't safe and may cause issues other than security. And since you probably have Android 9 it will take while to find a working exploit for it.
Obviously not, you can only "flash" if you have unlocked bootloader.
