Locking the bootloader?

Yesterday I read an german article about "GrapheneOS" and the possibility to (re)lock the bootloader after installing the OS, describing the exchange of the device key(or signature) of Google to a new one from GrapheneOS during the installation process so that you can lock the bootloader.

I remembered a question some time ago here about the possibility to do so in Lineage and the answer that this is not possible.

Maybe someone can explain this and the difference to GrapheneOS in simple words for me,

Thank you.

ad: now I am confused after reading a reddit post about "running LOS with a locked bootloader" https://www.reddit.com/r/LineageOS/comments/e99jdd/lineageos_with_locked_bootloader/

(running lineage-16.0-20191210-nightly-fajita)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] th.ritter:
I updated to 20191212 (via settings) and the configured fingerprint login was gone. When I go into settings and try to add fingerprint auth I am stuck with the "Touch the sensor" screen. The fingerprint icon is there, when I touch it, the green light goes on, but nothing else happens. When I leave the screen, the fingerprint icon stays on screen until I lock the display and unlock it by PIN.

Just updated to 2019-12-12 and now my wifi wont turn on at all. I was on 2019-11 something but i cant downgrade cause i dont keep older versions (i update through the settings). Mac address now shows up as 02:00:00:00:00:00 instead of what its supposed to be

For me lineage 16 wifi has never worked without flashing smurf kernel. I do not why it is like that for me but smurf kernel always had fix that issue.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Mar2ck:
Found 2019-11-10 build on my computer and downgraded to that and the wifi still wont work turn on even though that build used to work :/ tried smurf kernel and that didn't affect it. OxygenOS still has working wifi so no idea why LOS stopped working

Edit: Flashed blu_spark kernel and its working again on LOS :)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Mar2ck:
Like stackmagic said, fingerprint isn't working anymore as of 2019-12-16
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Dumb question

I was on lineageos 16, but wanted to flash OOS 10.3.0 to get latest modem etc... as with the new firmware vowifi is now possible for my carrier with the update...

So I:

1) booted to TWRP

2) format data

3) sideloaded OOS 10.3.0

4) booted to OOS 10.3.0

5) reboot to twrp via reboot to bootloader followed by fastboot boot twrp-Q

6) sideload OOS 10.3.0

7) reboot to OOS 10.3.0

8) reboot to twrp via reboot to bootloader followed by fastboot boot twrp-Q

9) format data

10) sideload lineage16

11) reboot to system

And I end up in fastboot mode not in lineage...

What am I missing here ?

Thanks for any tips

Can anybody confirm whether the fingerprint sensor is still broken, as of the latest 20191220 build?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Works for me on my self compiled 20191220 build.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
12-12 build both WiFi and fingerprint sensor work fine for me. I didn't see anything in the changelog for fajita after 12-12, so I haven't updated yet. Looks like one change for today so far. (12-21)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] th.ritter:
I just installed 20191220 and the fingerprint Sensor is still not working. Changrlog for the upcoming build shows a fingerprint.cpp fix, ignoring an error.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] th.ritter:
Addon: I just installed 20191222, with the fingerprint.cpp change. Still the same, I cannot get past the "touch the sensor" screen and when I go back or press home, the fingerprint icon stays on the screen, properly lighting up when touched, but does not do anything. It only goes away when I lock the screen and unlock via PIN.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
I updated to the 12-22 build, my fingerprint sensor is still working as expected, I can add them and use it as normal. Of course mine has been working throughout all these builds.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] th.ritter:
After today's update the sensor still does not accept fingerprints, but the sensor icon goes away when I leave the fingerprint settings page. That is new.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] b8842dc0:
Thanks [MENTION=3720814]OhioYJ[/MENTION]. I updated to the 12-22 build this morning. My fingerprint sensor continues to work. Much appreciated! Wondering if [MENTION=10381331]th.ritter[/MENTION] might be having some kind of hardware problem.

Thanks again!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] th.ritter:
After christmas I will try with the original Rom.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] th.ritter:
Well, it's been a hard ride. I installed OOS 9 via fastboot method, the fingerprint did not work. Then I upgraded to OOS 10 ("Improved fingerprint handling") and the fingerprint started working again. I then downgraded back to OOS 9 and the fingerprint worked there.

But even after the downgrade to OOS 9 I could not reinstall LOS, so ATM I reinstalled OOS and am using OOS 10 now, where everything works. Just to make sure that this is not a hardware problem as [MENTION=7070761]b8842dc0[/MENTION] suspected, I will contact OnePlus Support.

Can anybody reccomend a gcam port for me? Using the

port as reccomended by the google camera port hub, but I'm unable to take photos in the regular camera mode (perhaps due to hdr+?)

Thoughts?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
I've tried several from the Telegram GCam group, and I keep going back to one I downloaded a long time ago.

Gcam_6.1.021_Advanced_V1.7.190716.1800.apk

With this config file:

SG_ALL_Arnova_1.7.xml

That config file taken from here.

I then load xlib2s (Under Settings / Advanced / Libs). That XML file goes on your internal memory (not root) /GCam/Configs/

Maybe, a question of drivers OOS10 is for Q - LOS is based on Pie...but i may be wrong...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cnat:
Works great, thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Eventualy booting to los recovery and wiping data from there solved it...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Do others see this erroneous positionning of FOD from time to time (turn off and back on the screen usualy fixes it).

I'm guessing it's because the phone is not in portrait mode when the screen is turned on...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Just discovered a pretty big issue here. Seems that the flash isn't being timed when the picture is being taken (with any camera app, perhaps a kernel issue?) so the pictures taken in the dark always come out black. I'm gonna look for another kernel and report back if that fixes it.

Edit: Seems the kernel didnt fix the issue. This and the camera going out of focus issue when snapping a picture (which has been a problem for over a year now) are just driving me nuts.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Pastinakel:
Use another camera app. Footej works pretty well.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Like I mentioned, this is happening with every app that I try. It's always happened with lineage on this phone for me, even clean installed.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
I dont use the stock app, but I just tried it and got the same results as you. However GCam works perfect for me. I linked to the one I use, XML, and settings just a couple posts above yours for another user. Currently on the 8-Jan build of LOS 16. Stock Kernel.

So i need help. I got my OP6T yesterday and i unlocked the bootloader with fastboot oem unlock.

After that i boot up in OOS 10.3 got the devoloper option and activate usb debugging

Then i us the command "adb fastboot bootloader".

In fastboot i use fastboot boot "TWRP 3.3.1-31 Q Unofficial by mauronofrio".

TWRP is booting - i go the wipe advance - Cache and System .

Then i install the Lineage Rom but after the flash, TWRP say there is no OS installed.

If i reboot the phone i ended in fastboot. Only the Lineage Recovery is installed and if i use the ADB Sideload option, the rom is still not installed. :(
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] onliner:
You need Pie base (OOS 9) to use this ROM.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Serial Kazama:
That means if i flash Lineage 17.1 (unofficial) it should boot? I will give it a try. Thx mate
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] NozGojira:
Have anyone experience here that everytime you reboot on system you'll get stuck many times and need to reboot and reboot again until the phone get works. This rom is awesome but i don't want that kind of situation i thought i need to fresh install again
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Serial Kazama:
Okay i give up. I dont get Lineage 16 to boot up.

I downgrad to OOS 9.0.17 boot up, aktivate USB debbuging, boot to bootloader , boot TWRP flash Lineage OS and after that the twrp says open gapps arm64 error 64.

If i wan to reboot TWRP says no OS installed. -.-

I tryed the official and the unofficial TWRP.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
Wait, you booted TWRP, never installed it? Install TWRP, reboot to recovery. Start fresh, make sure you have 9.0.17 on both slots, not just one.

This is how I do it.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Serial Kazama:
Finaaaally thx [MENTION=3720814]OhioYJ[/MENTION] !!! Its booting and everything is working!!! wooohooo
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Having really weird issues today suddenly. I went into the city and systemui is crashing like crazy. Rebooted the phone, even flashed the latest nightly and it's still happening. Not sure why this would suddenly start unless an app updated and it's running in the background and crashing it. Going to try to grab a logcat later and diagnose it but just wanted to see quickly if anyone else started having issues this morning.

I wonder if the compiler crapped out with the updates having stopped for several days now.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZerBri:
Hello, everybody,

I have a problem with my 6T

I had installed the version (LOS 16) from January 18 all the time, today I wanted to install the version from January 28 via the update system. Download and installation worked, but my phone won't boot up anymore. Message: QUALCOMM CrashDump Mode

Unfortunately, I can only get into the LOS Recovery (Slot A), TWRP is no longer shown to me. Here I must probably change the slot. I can still get into the bootloader, unfortunately Secureboot = YES

Anyone got an idea? I want to avoid a fullwipe, otherwise I can't get my 2FA logins of the App Aegis.

Currently I only have access to a Linux laptop (Ubuntu)

Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZerBri:
Made it myself : "adb sideload LOS" (today's version) in the bootloader, reboot and it worked directly. got my complete data back.

Will never use the updater inside OS again.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Hp6t:
I'm in a similar situation, did you ever get this resolved? I was able to switch slots in twrp and got os to boot from that (slot-a in my case) but slot b always goes to fastboot? I am tmo 6t, used msmtool 9.0.11 for bootloader unlock, then flashed twrp and lineage 16, but LOS only works on slot a. twrp seems to work on both slots. To update nightlies I do same method you listed but can only get it to boot from slot-a.

Any help on what we are doing wrong that puts us in fastboot will be greatly appreviated
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Were you on 9.0.11 on slot b ? You need to be on same version on both slots before switching to los.

Could be an incompatible vendor issue.

Other solution I'd try (and have used when one slot was OK but not the other) is :

Go to recovery (and switch to slot a [that wich boots los] if not already on it)

1) On slot a : nandroid backup : data system boot and vendor (using _image for vendor and system if i recall correctly)

2) switch to slot b and reboot to recovery

3) nandroid restore : system boot and vendor

4) reboot to system (so on slot b)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Hp6t:
Thanks! I will give it a try when I get home this evening. I am not sure if I had 9.0.11 on both slots and did not think about that. Whatever the msmtool did is what I had before I flashed from that to LOS. Really appreciate the suggestions!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
This used to be easier because we had the fastboot images so you could just fastboot flash the new modem and whatnot, but it doesn't seem that we have those files/maybe with A/B it's not possible anymore. Is there any advantage to using sideload vs just doing a straight install of the rom? I've been looking to see if the would be a way to upgrade to the new firmware without losing and having to reinstall the data partition....
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] devon9954:
When you go from custom rom back to stock unfortunately you have to format data and when you do it, it will boot 10.3 up you will set it up then reinstall twrp make sure you also install twrp IMG in ramdisk on twrp then install twrp zip

Hello,

i tried to install LOS 16 several times on my 6t but i always ran into issues. Seems like i am blind.. :eek:.. what am missing?

My order:

1. reboot into recovery (latest TWRP)

2. perform a factory reset

3. install latest LOS16

4. install latest open gapps

5. reboot to recovery to flash magisk but:

as soon as i want to reboot to TWRP it is gone - i am getting into LOS Recovery.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] oscarmaldonado:
Hey bud, what you need to do in order for you to retain recovery TWRP is after every rom including stock you need to flash TWRP INSTALLER.ZIP after. So what you do:

Install latest LOS16

Install TWRP INSTALLER.ZIP

Reboot to recovery again

Install GAPPS and Magisk for root.

Good luck bud.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Lazar81:
It worked. Thx pal. TWRP and Magisk working. But now i saw that cts profile in magisk responds false... Any idea?

Edit: Forget about... Read a post before describing the same problem.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] oscarmaldonado:
Install these 2 modules with magisk: MAGISK PROPS CONFIG and SAFETY PATCH and that should fix your problem. Good luck bud.

Hi! I'm on the latest 1.0.3.1 build. If I would like to flash lineage how can I make sure that I have in both A and B slots the same 1.0.3.1 versions? I use lineage on my old Nexus 6 and Pixel XL and they are working perfectly only Nexus 6 is a bit slow and the battery is not in that good conditions but the OS itself is ok. I don't mind using the original system by OnePlus but the security patch is too old two months old and I don't think it's gonna be up to date ever. Secondly and actually this is my main problem that f*cked up auto brightness. In dark environment it's dim as hell. If I set the slider manually then a little bit later it's going back to minimum. Only solution is auto brightness off. But I wanna use it and not switch it off. On my other phones with lineage auto brightness works no matter it's night or day. So I just would like to know how to make sure about the two slots because I don't think that on my Pixel XL I have done it correctly because when there is a new OTA the update process takes hours. Thanks!

Can't get past twrp-zip install

Guys, please help me out 'cause i'm going crazy. I think i bricked/restored my 6t for like 100 times in the last week. I tried to follow the steps above, but after installing twrp installer zip (and rebooting to recovery), everything from the /sdcard folder seems to be garbled up (see attached photo). Basically I'm locked a this step as I can't continue to install files from the phone's memory and contiue the steps. Thanks!

Photo: [IMG="6T after twrp installer zip"]https://ibb.co/b7Bv88P[/IMG] (unfortunately I'm not allowed to post a link yet)

Basically what I see on /sdcard are just random folders with random letters/numbers
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
Are you coming from a different ROM, a really old version, or using an out of date TWRP? Assuming TWRP is up to date, you are going to have to format data to clear that up.

Here is how I install LOS. As mentioned in that post, replace the Android 10 parts with Android 9 equivalents since you want to do LOS 16.

---------- Post added at 07:05 PM ---------- Previous post was at 06:49 PM ----------

You shouldn't need both of those modules, use one or the other. The Safety patch one will make your phone show up as a Huawei so I would recommend the other. It's more customizable, and your phone will still show up as 6T if you want, or another device if you choose.

Magisk Hide Props Module can be downloaded Here.

It requires BusyBox to work, it can be found at the bottom of the first post here: [TOOLS][ZIPS][SCRIPTS] osm0sis' Odds and Ends [Multiple Devices/Platforms] .

Both of those ZIP files, can be installed from TWRP, or in Magisk. I install them from TWRP personally.

To activate the Module and choose options, you need a terminal emulator. Personally I use this Terminal Emulator for Android, you can use others though. In the terminal type:

su

Hit enter. Make sure Magisk gives the terminal root privileges, then type:

props

Choose option 1. Edit Device Fingerprint, then f - Pick a certified fingerprint, then choose whatever device you want. I'd recommend you just choose OnePlus 6T. Go through the menus, hit reboot after changing the fingerprint. Once this is in place everything should pass, from my phone just now (LOS 17, Magisk 20.3, with Magisk Props Hide Module, use same setup with several, LOS 16 devices too):
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Just as a general question, what is everyone using to migrate apps between ROM reinstalls nowadays? I've all but given up on Titanium as it's been unable to restore backup data on lineage 16 as of the last 6 months or so for me. I've also tried Migrate, but it too was giving errors on restoring the data. I'm wondering if this is symptomatic of an inherent issue with my app data or if both apps are just not working as intended with the recent versions of lineage for the 6t. Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] 5umi:
OhioYJ, you're a lifesaver! I finally managed to correctly flash twrp+lineageos to my 6t. It worked, however, only being on OOS 9.0.17 and following your instructions. Using the exact same set on OOS 10.3.1 did get me to a 'Qualcomm CrashDump Display' when booting. Of course I used the mauro-Q-image in this case, so i'm not really sure what's at fault. Anyways, I'm a happy LOS user now. Thank you, sir!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
Glad they worked for you. Those instructions were for a LOS 17 thread. If you noticed though the first sentence says if you are doing LOS 16 to use 9.0.17 instead of 10.3.1. Android 9 with Android 10 base or vice versa = crash dump mode.

---------- Post added at 08:20 PM ---------- Previous post was at 08:14 PM ----------

Its been a couple weeks since I was on LOS 16, but Titanium Backup was working. It's still working on current builds on my other devices. It's also still working on LOS 17 on my 6T.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Give Swift Backup a go. It's pretty similar to TiBu but with Material Design, Backup to Cloud and a lot of other Stuff. Hands down one of the best Backup App out there
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jsbeagle:
It took me forever to figure this out, but a change in android is the problem. Go into developer options and uncheck "verify apps over usb". This should allow TB to restore apps again. The hard part is remembering to do this the next time.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Wow! That should be a pop up in Titanium like the usb debugging notification if that's causing restoration to break across the board! Hopefully the dev is aware, thanks for that invaluable tip!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] 5umi:
I'm new to TWRP, but here's my question: why would you prefer TB or any other software over the Backup feature from TWRP?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sajeel:
hi

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] 5umi:
I can only link to this post from OhioYJ: Installation steps for LineageOS

Pay attention to the version of OOS you are coming from and proceed accordingly.

These steps have worked out for me, after much trouble and frustration.

Has anyone managed to get Edxposed working on this ROM? None of the versions I try seem to work. Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Working here !

See screenshot for magisk modules used.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Mostly because TB will allow you to flash another rom/a clean flash of a rom and then restore your apps and/or their respective data. This is helpful if you screw up the rom and it becomes unbootable, infected, slow, etc...and you want to start fresh or swap to a new rom without losing your app data (especially for the majority of us who don't want to give all of our personal data to Google through Google app backup).

TWRP Backup/Nandroid is great for backing up your ROM and reflashing it back to the exact state that it was at, filesystem, data, and all, in the case of screwing something up and effectively needing to undo what you did.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sajeel:
Brilliant followed and worked a treat the only thing to add was how to switch slots in twrp but im sure anyone flashing should be aware of that anyway.

Very happy with rom and stability well done again lineageos
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
Normally you shouldn't need to switch slots in TWRP. The ROM will automatically flash to the opposite slot, when you reboot to recovery it will reboot to that slot.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sajeel:
Ok was not aware of that am new to a/b slots thanks for all you lot without your help would not have achieved
