I have a new M8 and, for the moment, I want to keep it stock, but rooted. Is it possible to fastboot boot TWRP, flash SuperSU for root, and still be capable of receiving OTA updates, since TWRP isn't actually installed? I'm coming from a N4 and N10 where I didn't care so much about official OTAs, so I've never tried this.
Also, do I still have to unlock the bootloader first in order to use fastboot at all? And does having an unlocked bootloader prevent OTAs?

No, you can't root with a locked bootloader. That's the whole point (well, mostly) of a locked bootloader.
Also, its my strong opinion that OTAs have no place on a modded/rooted device. It won't work anyway, the OTA will check for root and fail to install. Or even if it did install, it would unroot the phone.
If you want to root, just do the whole deal, unlock bootloader, install custom recovery, etc. You can flash anything you want, including the awesome array of custom ROMs, or stock rooted ROMs for other carrier versions (which usually get released soon after the OTAs anyway).
Totally makes sense. Knowing me, it won't be long before I feel constricted with a locked bootloader (especially if I can't root}, but just wanted to see how "virgin" I can't keep the phone while I break it in. Plus I read a recommendation to use fastboot to boot into TWRP as an alternative to flashing it. But if I have to have an unlocked bootloader to do even that, I suppose I should just install TWRP and be done with it, like I'm used to.

Not sure what will happen if you try to boot TWRP with a locked bootloader. Maybe only one way to find out
But that would be purely academic. You can't flash SU or SuperSU, since you need write access to the system partition to do so (and therefore an unlocked bootloader), regardless of whether you can boot TWRP or not.

Great, that's exactly what I needed to know. I'll just wait a week or two, see if I'm happy with the phone and, if I am, just do it all. Thanks a lot.

Any one knows how to re-lock the bootloader of one plus 3???
And
How to remove that screen on boot up after unlocking one plus three??? :/
If you read the screen properly ull see the instructions on the screen itself do everything the same way you unlock the bootloader just instead of oem bootloader unlock type oem bootloader lock ...but make sure you're on stock rom and recovery

But then My root access will be wiped??
I want root access and dont want than annoying screen
two questions different answer but I would bet if there is a way to remove nag screen a google search would find it. Keep searching threads
there is no reason to re-lock bootloader, its still under warranty through Oneplus even with unlocked bootloader. but if u really want to
1. fastboot flash stock recovery (fastboot flash recovery recovery.img) (make sure u download the file, its somewhere here on the forums
2. reboot and then reboot to fastboot (fastboot oem lock) (i have never re locked a bootloader so i am not sure if it will rewipe ur device again like unlocking it does)
3. boot to OS and get developer options again and uncheck OEM Unlock (do this last)
i would not recommend re locking since it wont void warranty and seemed like a lot people screwed up their devices relocking it, but they also unchecked the oem unlock before flashing stock recovery, also i am not sure if step 2 is needed, i would just make sure u flash stock recovery 1st before doing anything
HELP

What part of be on stock OS is so hard to understand?
If you're not absolutely stock when relocking, you will brick your device.
Then good luck trying to enable OEM Unlocking when not being able to boot.
As someone who messes with their phone, relocking your bootloader is one of the worst possible things you can do.
If not done correctly, it WILL brick your device.
If you want to go back to stock, then surely do, there is absolutely no need to relock your boot loader unless you're selling your device to someone or if you're looking to pass SafetyNet for Android Pay or something.
Also, you cannot have the cake as well as eat it. You need to have an unlocked boot loader for root, exposed, etc. There is no way around this.
Phones previously had to be reverse engineered and exploited to gain root access, now OEMs freely allow unlocking.

I hope you can read this. I'm not a noob and I am looking to relock my bootloader because I am going to sell it. The person wants it fully stock so I need to relock the bootloader in order to regain access to official Ota updates.
I need to be on complete stock (stock recovery and rom) right? Would you please kindly point me to where I need to go to download the stock Rom and recovery. There's some TWRP flashable OTA zips on Oneplus forums that restore stock Rom and recovery but I want to be sure that that is enough and that I don't end up bricking my device for something as stupid as this. Any help would greatly be appreciated!

Fash 3.2.4 FW from here.
Follow all instructions from here (except I would suggest sideloading the StockROM before relocking).

I followed the same guide posted on OnePlus Forum to re-lock my bootloader. Just follow them, it works.
Here is that link from OnePlus forum.
1. I restored my stock rom backup from TWRP
2. Flashed Stock recovery
3. fastboot oem lock
4. Sideload stock ROM
Done.
I unlocked because stock ROM I felt was much stabler and hassle free. Have rooted and played with custom ROMs enough in my Nexus 5 days. Just too much stress and can end up with non-working features. Might root again in future if I find something compelling in custom ROM.

If you unlock bootloader and root device. Do you still get OTA updates if you stay on stock ROM?

If you unlock device, you will still be able to apply OTA. If you rooted by modifying the /system partition, OTA will fail, but if thou rooted using systemless method, you can apply OTA.
Iam on stock OOS 4.0.3 and i was plagued by the same error
--adb sideload the complete rom (with locked bootloader)-- method worked for me.
Previously i had unlocked bootloader and was on freedom OOS 2.3 with TWRP and then i realized that stock updates are better.
So i installed stock recovery and and tried to flash Stock Firmware 4.0.3 through sideload command and it failed.
then i installed TWRP and then installed stock OOS 4.0.3 and it installed fine but with some error.
Then i installed stock recovery
So i rebooted it and after long time it was installed but then i started getting dm_verity error and also i was frustated with unlocked bootloader message.
So i locked my boot loader first from fastboot oem lock and then sideloaded the stock 4.0.3 again and it really worked.
So now i am on stock rom and stock recovery and no more dm_verity error or unlocked bootloader msg to wait for 5 secs...
Now iam really loving my Oneplus 3..
Just got a 10 Factory Unlocked. I do need to root for Xprivacy and AdAway, etc. and of course, to make a nandroid. I suppose I could use ADB for such a thing, but TWRP surely does make life easier.
Since this is the first phone I've ever had that was already unlocked, I'm not quite sure where to start with rooting. I'm a little concerned because I'm seeing posts discussing how the radio might go wonky. Not ready to flash a custom ROM yet, I just want to dip my toe in the water for now.
I'd be grateful if someone could point the way.
BTW, the faceplate on my 10 is white, I was expecting black based on all the photos I've seen. Is this because I got the Factory Unlocked edition?
Thanks in advance!
is it on nougat or still marshmallow? i think nougat right? Xposed won't work on nougat anyway and you don't need to worry about the radio. if it's unlocked already and want to just root and you need to pass safetynet, get magisk v12. first you need to flash twrp and then flash the magisk zip to get root and be able to pass safetynet, be sure to not flash anything which modifies directly the system, otherwise no stock OTA and some apps won't work even if you use magisk hide
DeeZZ_NuuZZ said:

Haven't even turned the phone on yet - letting her charge to 100% before I do anything. I'm confused - why would I need to unlock the bootloader if I already have an unlocked phone? Or by 'Factory Unlocked' do they mean SIM unlocked, versus bootloader unlocked?

Not familiar with 'safetynet', and yes - I do need Xposed therefore it will modify the /system partition so far as I understand.
In any event, it sounds like the starting point is TWRP for anything to do with root, correct?

yes you need twrp, without it no root... the thing is there is no Xposed for nougat and I think your phone came with android 7/ nougat right? if yes, forget Xposed. but you can use apps like adaway with magisk too.
So that'S why you should search for the Magisk thread and read everything about it, before you proceed

No, the HTC 10 shipped with MM. I guess I'll have to fire her up and see where I'm at.
So, assuming that I'm on MM, then it's just TWRP, flash SuperSU from recovery, install Xposed and I'm off and running - nothing extra, correct?
How would I make a Nandroid of the current factory ROM (all partitions - not file based) using ADB just in case?

yea if MM then it's that easy.
full stock nandroid can be done in twrp, there you can backup system, data, boot and recovery
also the system image, but don't know if you need that, but you can try to backup it too, be sure to have enough space
I got my unit one year ago, now I want root, I got nougat us unlocked and I want stock ROM, how can I do?

flash magisk v12 then you have root and also can use android pay and other apps which needs passed safetynet
if you don't mind safetynet, you can also use systemless supersu
To the OP, surely factory unlocked indicates unlocked to all networks rather than bootloader unlocked ? Check this first to save some hassle. If the bootloader isn't unlocked yet, you could consider sunshine s off , it will cost you but on mm firmware you can s off and stay locked which can be an advantage. Worth checking bootloader status first though

What exactly do you need xposed for? It won't work once you updated to Nougat. And Nougat is much better tan Marshmallow at least as far as I'm concerned. All I need I've been able to find on custom ROMs and or by additional root Apps.

Probably worth updating via ota after sunshine to nougat, not before. You can stay locked and s off then. After ota you can root as usual

Can't go Nougat until Xposed is up and running.
So far:
Unlocked bootloader and went S-off via Sunshine
Installed TWRP
Made the error of allowing modification before taking a backup - not sure if I'm hosed.
Flashed SuperSU SR3 following Chainfire's instructions to send command via ADB
Flashed Xposed
Next: TiBu and restoring apps.

You won't ( probably ) be able to do further ota in the future with your modified backup as you're probably aware. But don't worry too much, it's likely the firmware you're after will be available elsewhere

No big deal. I'm not ready for Nougat until Xposed is running. However, HTC has an RUU available already, so we're good to go.

And of course, if I get bored, there are any number of custom ROMs available. I was running Maximus on my M9, I'd probably go that route again.
I know that the 5z can have it's bootloader unlocked, my concern is with the updates, is there anyway to keep getting updates after you root the phone.

Same as other devices I'd imagine. Flash a full OTA in fastboot, not incremental. Then flash root again.
Or flash stock recovery, update, then TWRP and root.
This is of course with TWRP support.
Unlocking the BL does not have an affect on OTAs.

ah, I was going off of a reddit post about the zenfone 4.
"I get security updates every 2 or 3 months and they're generally about one month behind. Bootloader unlock has a problem that they change the name of the phone or something so you can no longer use the official updates. This would not be a problem if there was a rom community but there isn't as of now (at least with z4p)"
Hey guys.
I'm reading the forum over and over, reading guides but still can't quite understand few things about magisk root.
1) Is it necessary to use TWRP for root using magisk? I found a guide to patch stock rom boot.img and then flash custom rom without TWRP. This way encryption also works (I read it doesn't if you use TWRP).
What is the purpose to use TWRP at all? What are the pros and cons of each method.
2) How is OTA update handled for Samsung with magisk? Do I have to revert back to stock rom using odin each time a new update appears?
Or I can do download OTA update, apply it, then without reboot, I just reinstall magisk from my phone and everything will work?
3) Can you make signed custom rom for samsung so you can lock bootloader after root, just like people do it for one plus on this forum?
Or it is not possible with samsung?
Thanks in advance for help.

Hello,
First off I would just let you know that typically questions like this go in the Q&A section.. This is S20/S20+/S20U Snapdragon Development thread which is usually reserved for people who develop things such as roms, twrp, mods etc. etc. so be sure to ready the rules and other stickied information when considering to post just to be sure you post in the right section.
So next thing I want to say is that in order to use TWRP or root or anything custom really on a usa Snapdragon model (U/U1/W Models) you have to use paid service to unlock the bootloader IF your device is eligible to be unlocked which means you haven't updated to the latest OS, if it is, then you are out of luck for now until new method is developed using new security.
If you are unlocked already, can unlock or just want to know I will try and answer your questions now.
1) TWRP is not necessary. Neither is patching the full ROM. All you need to do (if you don't want to use TWRP) is take the boot.img from the stock firmware, patch it using Magisk app and then flash it in ODIN. Device will wipe most likely if encryption and vbmeta etc. isn't disabled already. I do not know if "encryption" works while just rooted using Magisk patched boot.img or not as I usually disable all that stuff. My guess is that in some form it would be encrypted, just not sure if it's the same thing you are referring to or not.
2) If you are on an unlocked bootloader and complete stock i.e. no root or anything just clean full stock then you should get OTA updates. If you use anything "custom" i.e. Magisk patched boot.img or TWRP installed or vbmeta disabled etc. etc. then OTA updates will NOT work. And no, you don't have to revert to stock in ODIN each time there is a firmware update. It really depends on the update but you can typically use the odin tar with home csc and it should update without wiping but at the same time you would lose root or need to re-patch the new boot.img etc. etc. but wouldn't necessarily have to flash stock first then start over. There's also "safe" updates available some posted by jrkruse in development sections. If you had a usa unlocked device that was unlocked using paid service then you do NOT want to take OTA's because Samsung has changed the way tokens are verified when device boots up so new OS can't read them and most devices have incremented the bootloader so if you did take an OTA you likely would lost your unlock and no way to downgrade.
3) No. In order to do that you would need Samsung's private keys since there is no way to load your own custom key to use.. you can't just sign it with any key.. Also, if you relock your bootloader on a USA model that was unlocked using paid service then you will not be able to unlock again.. either way, it's not possible to use a custom signed firmware then relock the bootloader and have it boot.. not on Samsung anyway..
Hope that clears it up for you.
Thanks
