Have tried to find a definitive answer to this but am unsure.
Ran Lineage for a few weeks and happy but looking at getting another phone (maybe Nokia)....anyway
My question is, now I have gone back to stock and all booting nicely and is not rooted, what would happen if I relock the bootloader. If it's ok to relock is it via adb or just deselect the bootloader option in settings.
Sorry if this has been answered elsehwere. I just can't find the black and white, yes no answer.
Thanks
The answer was yes. I read a lot about bootloops etc but all ok with relock for me.
In case itns of any use here is what I did.
1. Restored to stock by using the post below. Although all I did was flash boot.img, recovery.img and system.img. Let it boot then when System UI crashes hold power which restarts then select restart to stock recovery from the 5 second menu and did a factory reset.

2. Relocked bootloader using fastboot oem lock from the link below
https://www.theandroidsoul.com/relock-bootloader-fastboot-android/
3. Stuck phone on ebay!!!!
Possible Silly Question
Do I have to erase the phones data if I re-lock the bootloader? — I suppose I would just have to make a backup, but I'm stuck between not being able to root it and not being able to re-lock the, so far, useless features of the unlocked bootloader.

If the RUU doesn't work, the other two alternatives are to attempt to flash the stock system.img and stock boot.img through fastboot .. although I'm not sure this will work with S-ON, depends on whether or not the device is locked/unlocked via HTC's official method.
Also, the second alternative, could use the PG*zip file which is stored inside the RUU. the zip file can be extracted from the RUU and placed on the root of the sdcard. Then the bootloader will grab this file and flash, essentially performing the same thing as the RUU would.
Due to a bug, I have been able to get root on my OnePlus 2 running Oxygen 2.1.1 without a wipe.
DISCLAIMER: This may not give you root on yours, and obviously it may also loose you data, so don't do it unless you know you can cope with that. YMMV, but I've documented here for posterity how to do it!
I had unlocked the bootloader previously, because my device is an import, so it is possible, though unlikely that it simply doesn't wipe on an unlock after re-lock (OTA locks bootloader).
The basic steps are :
Encrypt your device
Unlock the bootloader (this won't wipe because of encryption!)
Boot TWRP
use adb to push SuperSu to your device and then flash it
Then you will have root. Step by step instructions below.
Note that TWRP currently doesn't support encryption on our devices, so you'll have to use something other than that to back up your data if you want to use a custom rom. This simply gives you rooted stock Oxygen.
After rooting :
Code:
$ adb shell
[email protected]:/ $ su
[email protected]:/ # id
uid=0(root) gid=0(root) context=u:r:init:s0
Step 1: Encrypt your device.
This is irritating but fairly simple. You have to have fully charged your device AND keep it plugged in, and it takes ~50 minutes to complete. It's the standard android encryption, so follow any guide for this, such as https://support.google.com/nexus/answer/2844831?hl=en-GB
Step 2: Unlock the bootloader.
Again, this is well documented - here's a guide : http://forum.xda-developers.com/oneplus-2/general/guides-how-to-guides-beginners-t3146568 - The important thing is that if you're encrypted, this does not do a wipe, in my experience.
Step 3: Boot TWRP
Download TWRP from https://dl.twrp.me/oneplus2/ and save it somewhere you can find it later - I'm going to assume you're on linux and have saved it in ~/Downloads/TWRP.img
Reboot into bootloader mode (Power and Volume up) and start TWRP by issuing the following command (substituting your path to twrp) :
Code:
~$ fastboot boot Downloads/twrp-2.8.7.0-oneplus2.img
Step 4: Root it!
This is a bit tricky because once you're encrypted you can't access the SDCard, so you need a bit of magic to flash the zip.
First, do the swipe to enable modifications, then in mount, tick the /system option.
Then, on your PC, download SuperSU's .zip update from https://download.chainfire.eu/696/supersu/ (similar to above, assuming same download location) and use adb push to put it on the device in /tmp :
Code:
adb push Downloads/UPDATE-SuperSU-v2.46.zip /tmp/su.zip
Next, from the main TWRP menu, select Install. Navigate up (you start in sdcard that is empty) and into tmp, then select the su.zip file in there.
Swipe to install the zip - TWRP will complain because it can't access /data, but handily, /data is not needed to root!
Select Reboot, and viola, you have SuperSU and root! Now you can install Titanium Backup and back up your device.
Cool, perhaps renaming the title like "Unlock and root without wiping" could make more sense?

OTAs don't re-lock the bootloader though...
If you've unlocked it previously, it'll stay unlocked unless you boot into fastboot mode and do a "fastboot oem lock".

Not true I'm afraid. The OP2 OTA to 2.1.0 did indeed relock the bootloader. I know this because I would never want to lock the bootloader, and I'm on a Chinese OP2 which came with masses of spyware, so to install clean 2.0.1 I had to unlock the bootloader originally (they managed to get the spyware into the recovery image!). Anyway, it's irrelevant to this thread how the bootloader got relocked, I just documented this fiddly way of getting an unlocked bootloader with root on a locked OP2.

Maybe my post should have said "OTAs don't re-lock the bootloader since 2.1.0"
Anyway, if your method works then great :good:
There's another way to do it here.
Can everyone who's done this attest that the data indeed doesn't get wiped?

Confirmed on 2.2.0 or still on 2.1.X?
Can confirm, this still works on 2.2.0.
i didnt try this tutorial, but when i rooted my phone, my data didnt got wiped either.
will root on 6p running android n dev preview wipe phone?
Any chance this works also on 1+1? I'm desperate for a way to root without unlocking so I can install titanium/nandroid and do a full proper backup before wiping clean (battery life is utter crap). Running latest stock 6.01 COS. Never unlocked, never wiped since 15R.
Thanks!
anyone tried this on OOS 3 ?
Yeah, bump!
Now my OP2 is on Oxygen 3.0.2, and Android 6.0.1 - stock.
My phone had always been (bootloader) unlocked and rooted, since the day after I got it.
But to get the new OTA update to Oxygen 3, I tried a different method this time, where some people said you can do a temporary un-root, get the stock OTA update, and then re-root.
I followed their instructions, but I can't re-root as simple and easy as they said.
Before the process, I didn't do a nandroid backup because my sdcard doesn't have room :-|
So now I need to re-root without losing data.
And I've tried helium before, many times, and it never works for me.
Any other ideas, or has anyone tried this encryption trick yet with Oxygen 3?
Thanks!
tried it on oos 3.1:
everything worked until a bootloop at the last restart.
also twrp asked me to unlock the phone, i did that.
what to do now?
Did anyone ever have any success with this approach on 3.1?
LoL How do you boot/flash TWRP on locked bootloader?

Lol, you can't.
hey everyone. trying to OEM unlock the TWRP bootloader. When I type "fastboot OEM unlock" it will reboot into TWRP bootloader, and nothing unlocks. I know this because when I type "fastboot oem device-info" it says "unlocked FALSE".
I have OEM unlock and USB debugging enabled.
This is a phone with previously successfully installed CM13, and now I'm trying to revert to stock/unrooted. I can't seem to flash the recovery at all here because I can't get the damn thing to unlock.
Any ideas?
Did you lock the bootloader ? If your flashing Roms and custom recoverys imagine its already unlocked. Bootloader won't lock itself. If you want full stock just flash any OS2 firmware with twrp. You can worry about stock recovery after. I would just leave the bootloader unlocked won't hurt anything.
I had the same issue not long ago. Finally, i used the mega unbrick guide, but warning, all the data is lost
Ps: Sorry for bad english
hey, thanks for the response. I have been following the following tutorial (and others similar for installing CM13):
(great, website won't let me post it here... it's the unlockr oneplus x guide)
so yes, I originally flashed the stock recovery and replaced it with the one from the tutorial. There were a few hiccups during setup, which may have affected why I can't easily update nightly now, so now I'm trying to revert to the unrooted stock state so I can try from scratch, hopefully fixing the issues I'm seeing now. The problem is that I can't flash the recovery using the stock recovery... I can't even update the damn recovery because it's locked. Is this what is meant by a 'soft brick' ?
I'm really out of ideas to what's causing this so I could use some help.
My tablet has been fine for a long time and has had many roms on it previously. I have been on rooted stock however for over a year now and decided to try a rom again....
However I have tried 3 different roms now all with catastrophic problems. I install them fine through twrp along with gapps then reset Tablet but get a black screen with just a blinking charge light if it's plugged in. No boot logo or anything.
I managed to revert back to stock about 5 times today through flash mode and flash tool but I don't know what's going on.
I rooted, turned on debugging and reflashed twrp but it keeps happening across different android versions too. I thought maybe I had relocked bootloader so I tried to check through adb oem but it freezes, so I ran the unlock command just in case through adb and it was fine but still freezes.
Any ideas?
To add to this I just downloaded a dialer app on stock to check bootloader unlock status.
It says bootloader can be unlocked but nothing about its actual status. I'm more or less certain this is the issue now so can anyone advise what to do? I manually tried unlocking bootloader and it just restarted like everything was fine but nothing changed.

I'm not an expert to be honest but I would try that:
put your tablet in fastboot mode, connect it to your pc and in fastboot type
"fastboot flash boot twrp.img"
Now you should have TWRP.
If this work your bootloader should be unlocked otherwise I think you should see some error in fastboot
Once you have twrp I suggest you to flash resurrection remix 5.7.0 (android 6.0.1). I suggest it just because it worked without problem with my tablet Z.
Something not clear to me: you started just with a rooted stock ROM or you unlocked bootloader, flashed TWRP and then your ROM?
I started with rooted stock rom, I am using dual recovery that seems to be working fine (it was faster since its just a bat file). I originally rooted using kingroot on stock which I used to flash stock rom prerooted with supersu with twrp.
If I try the same process with anything that isn't stock it's black screen on reboot. No Sony logo or anything.
Ive tried changing recovery to newest twrp, changing sd card to a different one, different ROMs including the one you mentioned because that's the one I wanted to try. I also tried with and without black kernel. None made any difference. Black screen boot everytime with just a blinking light on side like its got no OS installed at all.
Just to clarify, my bootloader should be unlocked. I've checked but if I run the adb command to check it just freezes like it's eternally loading. Using dialer go check it doesn't even display anything about it aside from the fact it can be unlocked.
what command do you type? "fastboot oem device-info"?
ok so I have an update, something is definitely messed up with my bootloader.
I tried to relock bootloader from fastboot but its also stuck in a loading cycle for no reason. It seems on some level my bootloader is unlocked because I can flash recoveries fine, but when I come to put a new ROM on the device it won't let me and black screens.
From fastboots I used the commands 'fastboot oem lock' and I just get '...' forever underneath. If I use 'fastboot devices' my device is listed, if I use 'fastboot -i 0x0fce oem unlock 0xbootloadercodehere' it fails the first time, then works the second time and says ok but its clearly done nothing when the device reboots. 'fastboot oem device-info' also leaves me with the '...' on command prompt forever too.
I have no idea what to do if bootloader is screwy at all.

Yup that's what I used. I'm pretty sure bootloader is borked somehow though. I tried reinstall from Sony software too which hasn't changed anything.

I just tried with my XTZ and "fastboot oem device-info" just froze, it had 3 dot and nothing else. In my OPO it worked.
I'm gonna search something else...
Whats weird is my tablet also won't install anything on TWRP, I just tried installing SuperSU from it to see if it would work (having to use Kingroot atm) and it just does nothing.
I think this is the issue since I'm factory resetting before installing a ROM, which is therefore wiping my system and when I come to reset because TWRP isn't installing anything its acting like there isn't a system installed.
I can install via ADB fine, just when it comes to recovery... system says no. Its weird because its like its got a locked bootloader or something but even though I reinstalled using Sony software its still the same. If I try unlock bootloader again, I get an error first time then it says OKAY and does nothing.

According to an other post this should mean that your bootloader is locked but can be unlocked via Sony's code. At the same time I've read in the same post (can't find it) that people with unlocked bootloader still have "bootloader can be unlocked" even if they successfully unlocked it...
Unfortunately I can't try it myself because I'm on RR and the code *#*#7378423#*#* (this should be the code you used) doesn't do anything.
I have the code and have used it previously I have also retried it just to make sure.
When I type the dialer code above I get 'bootloader can be unlocked: yes' but nothing mentioning the actual current state of bootloader.
This is what's leading me to think it's a bootloader glitch because all posts I've seen should say 'bootloader unlocked: yes' or 'bootloader unlocked: no'. I get neither.
Been a few days and had no suggestions. Anyone got any ideas at all outside what I have mentioned? Getting pretty desperate because wifi is really bad on stock, getting constant slowdowns and stalls for no reason. I'm gonna end up trying to sell second hand if I can't do anything.

Sorry, I'm out of ideas
The only thing I can tell you is what I did to my XPZ, but I doubt it may help you:
1) Unlock bootloader using Sony's guide
2) XPZ in fastboot mode → from pc "fastboot flash boot twrp.img" (assuming you have the proper TWRP image named twrp in the same folder of fastboot)
3) flashed RR 5.7.0 and Gapps
4) RR change the rocovery to CMrecovery but I "easily" changed back to twrp using a guide under RR thread.
Hello ! So I got this one max, it suddenly started to bootloop out of no where. So I decided to unlock bootloader and flash a stock rom.
However, after flashing the unlocktoken, the screen on my one max asks if I'm sure I want to proceed, I select yes but the phone just restarts and the phone doesn't unlock.I said to myself maybe if i flash a firmware it will work, i typed "fastboot oem rebootRUU" but the phone just restarted instead of giving me the black screen with grey HTC logo
HTC DEV website is where you need to go and follow on-screen instructions to completely and successfully unlock your bootloader.
For stock rom flashing you don't need to unlock bootloader unless you're planning on Rooting and installing Custom Recovery, at this point it seems that you're stock. You need to either adb a custom recovery and flash a firmware or you're stuck and only need to adb over stock IMG file perhaps or something of the sort. I would recommend googling this and see what you find.
I myself have a problem... I cannot seem to re-lock my bootloader, I have followed every single guide in the entire world... Including Scotty's Guide here on XDA. I even tried to GURU Zip Aroma Installer, didn't work either. It's a waste of time.
Sometimes you get stuck bad. GL
