[Q]Stuff to do before unlocking bootloader/root - OnePlus 3T Questions & Answers

So I just got My OnePlus 3T and like most, would like it rooted! I have had experience with rooting and unlocking bootloader, but since My earlier devices were by Sony, there is a lot of difference. In Sony devices, there was no need to unlock bootloader to root, but it seems that for rooting 3T, I need to unlock bootloader. Even that doesn't seem difficult since there is this great guide with a toolkit. But My concern is that do I need to backup any partition before I unlock bootloader? Like in Sony we had a TA partition, which could be backed up before unlocking bootloader and would get wiped after unlocking bootloader. This is just for keeping it as backup and restore it to device if I decide to lock bootloader again. Also, will I loose anything if I unlock bootloader? Such as anything specific to OEM or camera functionality?

Nope. On OP devices there's no permanent penalty for unlocking. If you ever want to go back, you can re-lock the bootloader. But: unlocking and locking will wipe your phone. So you can't carry over root to a locked bootloader.

Okay, that helps! So to return back to locked bootloader everything would need to be like stock(no root, custom recovery etc.)
I had read somewhere about EFS backup and that it is related to IMEI number of the phone. This need to be done before or after the rooting process?
Also, would I need to disable encryption (as it is seen enabled in settings) and remove the fingerprint lock option before unlocking bootloader?
And just to be clear, I'm going to do following steps in the sequence to flash TWRP and root, Please let Me know if it is correct:
1. Unlock bootloader
2. Flash TWRP.
3. Flash SuperUser
all this with the help of ToolKit of OnePlus 3T. I don't need to take backup as the phone is new.
Also, I will be flashing the phh SuperUser for support with Magisk as mentioned here.

Hey, do you guys know if you can get official OTAs if you have TWRP installed?

Former Z2 user here @Mirhawk
I did the advice backup as a precaution. Then did your 1,2,3 steps. May I ask, why Magisk? Is Android Pay currently working with stock ROM + Root + unlocked bootloader?

AFAIK stock recovery is required. Otherwise install zip manually via downloads.oneplus.net

I'm not interested in Android Pay, as it doesn't work in My country, It is Pokemon Go I wanted, but I guess it doesn't work. Thanks for the infor though! It was a lot simple in Sony!

Is this device brickeable?

Hi!
I just got this phone today (Finally!) and i love it, but i want to get rid of all the bloatware from installed there by my carrier company, so i need to root the phone, right? I'd also love to flash ROM when we finally get some...
But my question here is... How birckeable is the xt890? Are all the rooting methods posted here safe?
Do we have any un-brick methods such as with NVflash?
Thanks!

Yes, you need to root to remove bloat included in your ~/system/app/ and ~/system/vendor/app/ folders. Easiet way is flashing a different fastboot XML file to a bloat-free carrier (like Retail EU or Retail GB).
As long as you do not go out of your way to remove both the bootloader and the bootloader backup file you won't be bricking.
We have plenty of fastboot restore files, but many require you to be unlocked bootloader to use. Honestly, I see people "brick" here from time to time and its because they never unlocked their bootloader.
None of the rooting methods will brick you or have a risk of it. Unlocking it is the least painful way to do so, motofail2go requires button combos and can be confusing.
We do have a ROM, but the guy posting (papi92) resides over at DroidRZR.com, if you want to test it I would PM him here or whatever you want.
We unbrick with fastboot. I have never broken fastboot and don't want to try
Enjoy your new device, remember though that Questions go into the Q&A forum.

Thank you very much for your reply.
I'm already rooted and have removed all bloatware, and are super happy with the device.
I was however unable to unlock my bootloader, this because when I enter the IMEI-related code corresponding to my phone on the Motorola webpage, it tells me that my device is not a candidate to get its bootloader unlocked.
This is why i had to root with Motofail2go. Im guessing not having my bootloader unlocked will be a big obstacle in the future when new ROMs start coming out. is that right=?
You should definitely grap Mattlgroffs Root Keeper Port for the i! If your BL isn't unlockable, you will lose root as soon as you get an OTA Update. The new OTA's are NOT rootable with Motofail2go!

[Q] Locking, Unlocking, DRM, what do you lose?

Hi,
Just ordered my z3c, looking to put CM12 on it. I'm coming from a Nexus 5 but I've used Samsung devices where there was just about no reason to keep the stock rom, but never heard of DRM apps and functionality in those... I've read a bit about the locking/rooting/DRM situation with these phones, but I haven't found a good, detailed answer on what it is that you actually lose by flashing a custom ROM like CM12 and/or unlocking the bootloader. So my question:
-What apps/functionality is lost when unlocking the bootloader?
-Does losing the DRM keys even apply to CM12, since I'm guessing they can't be used by anything in CM12?
-Do I need to unlock my bootloader to flash CM12? No TWRP from what I've gathered, but you can flash the CM recovery?
Thanks for the help.
Correct me if I'm wrong...

I have read that it's stuff like TrackID, Bravia engine, PS4 Remote Play?

Yes, because in order to flash CM12, you need to flash a custom kernel. Locked bootloader will not accept custom kernel. So bootloader must be unlocked.
-Do I need to unlock my bootloader to flash CM12? No TWRP from what I've gathered, but you can flash the CM recovery?
Click to expand...
Click to collapse
See above. For this phone, custom recovery is possible with a locked bootloader, as long as Root has been achieved. This doesn't mean you can go ahead and flash CM12 though! But you can flash custom roms that are based on the stock Sony kernel. (Make sure to check the post - some custom roms may be based on a certain build of the stock kernel, so you'd have to make sure your phone's stock rom/kernel is aligned with that)
Another thing to note is that it should be possible to backup your DRM keys (your TA?) if you have root on your device. This would allow you to restore the DRM stuff when/if you decide to re-lock the bootloader. Backing up the DRM stuff can only be done BEFORE the first unlock of the bootloader. Once it's unlocked, DRM is gone.

And the low-light improvement camera function as well - there is a patch over at the cross device section, but you should be aware of it nevertheless

yes, very important - once you root make sure to backup the DRM keys even if you're not going to unlock the bl and save a copy on several locations.
So from more research, the low-light improvement (probably the most significant loss), wouldn't matter if I used CM12, with the Google Camera, as it is a function of the Sony proprietary camera rather than a function of the underlying phone/camera firmware, correct? Would this be true of the noise cancellation and other functions, baked into the ROM/apps and not a function of the firmware?
I'll still backup the DRM keys in case I need them in the future...no harm in doing so anyway.
There's a thread comparing how photos look before & after losing DRM. This may help you. The low-light one is where you see a pretty big difference.

What about miracast and chromecast features? Any influence on this?

So my question is if you unlock the bootloader . You can restore the DRM so that funtion is back whilst keeping the bootloader unlocked?? Correct??

No , restoring DRMs will automatically relock bootloader and you will only be able to run them with rooted/unrooted stock firmware.
Though it is possible to restore DRM functions on custom roms but your keys are still gone. (until you restore them but then the rom wont run anymore since you willl softbrick your phone)

Thanks for your answer .
I checked the thread but for that fix you do need a locked bootloader? So CM won't work?
The fix it more that you can restore the functionality you lost when you lost your DRM and need to restore functionality?
Anyways I am obviously going to back them up but still would wanna understand it correctly.
Am a little confused here. ??.

And with custom Roms you mean based on Sony stock I presume

No you need an unlocked bootloader, there would be no point to restore DRMs on locked ones since you still have them . CM cannot work with intact DRM since they require a locked bootloader. CM 12 will only run with an unlocked one.--> DRM keys gone. But as CM 12 is not based on Sony stock it actually makes no use of the technology driven by the DRM keys. So there is no fix to "imitate" DRM keys like with stock based custom roms. This would only be possible if somebody manages to port the stock sony software to CM 12 (after lollipop release ) and make the device think its running stock with intact DRMs. And i dont even know if that is possible.

Root without unlock bootloader?

I am a newbie for nexus lineup. I am going to jump to N6 from oneplus one. As far as i know from search, every post says N6 can only root after unlock bootloader. So i just want to know can i root without unlock bootloader? And is it possible to get update OS from OTA after bootloader unlock?

you cant root your device without unlocking the bootloader. to root, you need to flash a custom recovery, then flash the supersu.zip file. none of which tou can do with a locked bootloader. in order to flash a custom recovery, you need to unlick the bootloader. and you will get an ota with root, but you cant apply it, so its pointless.

You may be able to do this by using chainfire's autoroot tool. But why the reluctance to unlock? It's not difficult. Unlocked bootloader has no effect on accepting OTA. On the other hand, root will prevent you from accepting OTA. It's easy to fastboot flash back to stock when a new OTA becomes available. And it's even easier to download the Google factory images and fastboot flash them. Plenty of "how to" threads on the general section.
With that said, the only reason I can see for not unlocking your bootloader would be if your employer has restrictions, or your are really worried about someone stealing your device and getting your personal information.

Will CF-Root Wipe My Data?

I see mixed info about this. I'm on stock 6.0.1 with the bootloader unlocked. If I root using CF-root, will my user data get wiped?
The CF-root screen says it will. The documentation says it will only if the phone is not OEM unlocked yet. Another online source said only if the data is encrypted.
If it will, how do I make a complete system backup before using CF-root? I don't want to try something until I have a backup.

when you unlock your bootloader, itll wipe your whole phone, including your storage. and that is normal, and has been like that since the very beginning.

complete backup.. with adb or with root. non-root you can backup some stuff, or backup with adb.

it shouldnt. but thats just an "app", if it will or not i dont know. if you root your phone properly, the right way, it wont. by the right way, i mean fastboot flash twrp recovery, then flash supersu with twrp recovery and boot up. it takes about two minutes.. do you need something else to do it for you, really?

Yes but how are you going to flash it? With stock recovery its not possible. Btw locking a bootloader when you plan to root or use mods is NEVER a good idea, besides that in the case of OnePlus it doesn`t void warranty so it would be unwise to not unlock or relock the bootloader.
If your device gets bricked while your bootloader is locked, you're going to get screwed. The most you can hope for is a complete phone reformat through one of the unbrick guides
