Hello which way is best to update the firmware (OOS11)

Preferably without data loss. I just installed lineage-18.1-20210826 with TWRP recovery.

1. using the method https://wiki.lineageos.org/devices/fajita/fw_update

2. or this one

1. Boot TWRP

2. Flash OOS

3. Flash Lineage

4. Flash TWRP installer

5. Reboot recovery

6. Flash gaps

7. Flash copy partition zip

8. Reboot system

With the second it would also work with a TWRP backup if the data is lost?

Is it better to first flash the version of lineage-18.1-20210902 or lineage-18.1-20210909 before I update the firmware. Without the firmware update, the ANT + and DASH versions no longer work https://review.lineageos.org/c/LineageOS/android_device_oneplus_sdm845-common/+/315213 right?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] AluminumTank:
Yes, I agree, this would be ideal. Unfortunately the updates have been sporadic at best. While right now they are somewhat regular (~3 updates in the past month), that has not always been the case.

And on top of that, it is annoying to switch back and forth between their builds and mine since you have to use the key migration script/zip every time you switch.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] AluminumTank:
First of all, you need to flash a lineage build after 9/2.

After that, I would say the best way is to use the instructions at https://wiki.lineageos.org/devices/fajita/fw_update. Only caveat is that you need to be on the international firmware already. If you don't have a carrier branded phone, then you are already set. If you do have a carrier branded phone, that's ok as well, as long as you've previously converted it to the international firmware.

The second way seems convoluted and pointless since the first way exists and is known to work.

Problem trying to update to lineage-18.1-20210909-nightly-fajita-signed.zip from lineage-18.1-20210819. I first tried to update using Lineage updater but that failed. I then tried the push-update.sh script which also failed. Finally I tried the adb sideload in Lineage Recovery, but that lead to inability to get out of fastboot mode. Any suggestions?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kendallgreen:
Problem may have been linked to old firmware. I updated the firmware using the Lineage fastboot method. Will try again but Lineage 20210909 still has the August security update. I can't seem to sideload open_gapps after sideloading LineageOS. I am left without any google apps
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Saksham03:
For R firmware, people are complaining about TWRP boot..

So for the second method.

Instead of TWRP use lineage recovery and instead of flash use adb sideload.

I would recommend to use the official method supported by Lineage.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] chief_wigum:
OK is that possible without data loss?

There are two more problems, what about the root, will that be retained? I also have MagiskHide Props Config so that the streaming service works, are there any problems?

I am trying to update the baseband but I am unsure on the correct procedure.

I have downloaded the latest Stock Android 11 rom and this is where it gets a bit hazy for me.

Do I have to extract all the roms contents into minimal adb and go to lineague recovery fastbootd and run the commands from minimal adb.

So has anyone had any issue with Google related functions not working when clicking on them? Install a app or update a app in play store, click on it and doesn't do anything, restart phone and it works for a bit then have to do it again to register clicking on update ... Or when logging if with Google account, when choosing a Google account it won't register till a restart and clicking again. Or wanting to add a photo from Google photos, only fresh restarts allow it... It has become annoying ... I have tried just installing oos and it still happens ... Then updated to oos11 then lineage ... And still happens... Fresh installs without backup install and still same issue... Think my phone is ****ed

Hey guys,

Just bought a T-Mobile Oneplus 6T off a buddy, haven't messed with an android since the 2013 Moto G.

I've battling with it since Saturday trying to get LineageOS 18.1 installed with no luck. So far I've managed to:

-Flash global rom

-Update to latest Oxygen OTA

-Unlock bootloader

-Install TWRP

When I get to the installing lineage part using this guide, I always end up only able to boot into fastboot and recovery.

I've tried a bunch of methods I've seen online for different variations of wiping different things at different points in the installation.

It may just be some version issue I'm unaware of. When I was trying to get it updated and TWRP installed I figured out after a few attempts that I had to update from 9.0.11 to 9.0.17 before updating to 10.

Currently running:

-OxygenOS 10.3.12

-TWRP 3.5.2

Thanks!

Since the 09/02 build, bluetooth audio became very compressed. Changing "Select maximum number of connected Bluetooth audio devices" to one fixed this for me. Not sure if this is a bug or not since I only have 1 Bluetooth device connected at a time.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] AluminumTank:
EDIT: Also should note that I had already gone through the T-Mobile specific bootloader unlock process before doing all of this. Specifically, I followed this guide starting at heading "For those with a OnePlus 6T bought through T-Mobile".

I took some (short) notes on the process after trying to follow the same guide, so here they are. Hope they help :)

For fastboot flash, I used OnePlus6TOxygen_34_OTA_046_all_2005052113_26a111bd1040285.zip, but probably different versions will work (preferably newer). Make sure to check that the .img files in the firmware zip match up with the flash script.

detailed steps:

1. Unzip OOS firmware and use the script "flash-all-partitions-fastboot-DESTRUCTIVE.sh" to wipe userdata (fastboot -w) and flash all partitions. This wipes userdata, thus the DESTRUCTIVE in the name.

2. Boot OOS. If there are issues, it will probably dump to recovery. In that case, just use recovery to wipe data AND cache. Then trying booting again, should work now.

3. Let boot normally. (Optional: use built-in updater to get to latest OOS, not sure if necessary since you can also just follow https://wiki.lineageos.org/devices/fajita/fw_update to flash firmware after installing Lineage.)

4. Then, drop into fastboot. Powering off, holding VolUp+VolDown+Power all at same time seems to work. You could also enable Developer Options -> USB debugging in OOS and do `fastboot reboot bootloader`.

5. Boot TWRP (fastboot boot <twrp.img>).

6. Flash TWRP installer, reboot to recovery.

7. Wipe (Factory Reset AND Format Data). Then reboot to recovery.

8. Flash ROM, flash TWRP installer, reboot recovery.

9. (OPTIONAL:) Flash ROM, flash TWRP installer (if recovery wanted, but recommend sticking with the default Lineage Recovery), reboot system.

10. Done.

Firstly I apologize if this is the incorrect thread.

Secondly, the matter at hand, I am stumped with an issue of installing Lineage 18.1 onto my Oneplus 6T McLaren (I dont think the McLaren makes a difference but I thought I'd ought to mention in case it does). I followed the guide on https://lineageosroms.com/fajita/ word for word and the installation said it completed with status 0. I reboot however, and it goes straight into the bootloader then fastboot and if I try to start again the boot it does the same and if I go into recovery and flash again it does the same. Lineage never seems to able to boot, the phone always goes into the bootloader and then fastboot.

I would appreciate any help you could give. The lineage install replaced TWRP with Lineage's recovery and so I think my first inclination is to flash again TWRP and start over.

Thanks,

Isaac

Did you update your firmware ? ... because the latest builds require the latest Android 11 stock ROM firmware.

If needed, you can download the required files for updating your fw here (unzip and follow the official instructions ... use LOS recovery in fastbootD mode).
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] isaachilly:
Hi Eric,

Thank you for the reply.

I did not update my firmware so that may have been the or at least an issue.

I unfortunately now have a larger issue. I carried out what I said I was going to do of getting back to TWRP. I pushed it and installed it on the phone. I then powered off the phone and turned it back on to it always going into fastboot and the fastboot options of recovery or bootloader always returning me back to the fastboot menu. I believe this may be a brick esque issue. Please may I request help again?

Isaac,

What's the simplest way to convert from Tmobile to International if you're already unlocked the bootloader and are using LOS? Ideally, I'd love to do it in conjunction with flashing the vendor partitions to 11 without losing my current install and data. From what I can see, there are two ways to perform the Tmob to Intl flash: 1) original way that requires you to unlock the bootloader first (not an issue) but uses older version 9 firmware files and 2) Some .exe you can install on windows and run even with a locked bootloader (less appealing way for me -- rather not install exe's on windows if I can avoid it).

How to Convert T-Mobile OnePlus 6T to International OnePlus 6T version

OnePlus 6T made a lot of hype this year during its release. A major reason for the hype was it entered the US market, by beginning partnership with

www.getdroidtips.com

This looks like it copies files over to partitions similar to :

Update firmware on fajita | LineageOS Wiki

wiki.lineageos.org

But maybe there are other changes as well? And the fw_update page from LOS has a big warning on it not to do it with carrier branded variants.

Can I do the top link's procedure, then immediately follow it with the LOS link's procedure, then reflash the latest ROM -- all without wiping apps/data caches?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Eric_Lev:
@isaachilly

0- Don't use TWRP.

1- Flash via fastboot the latest los recovery and follow the official instructions :

Found this:

Edited /system/default.prop

Uninstalled Magisk from app

After reboot no more issues with apps detecting root.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] optimumpro:
Unfortunately, reality is much more complicated:

Good apps that rely on Safetynet will never identify you for this setting alone. They also look at a bunch of other things, such as the status of your bootloader, and I bet 99.9% of custom rom users have unlocked bootloaders. You need provisions in the rom and kernel (which actually most roms have) to fool Safetynet, and it is still not enough, because detection gets better every day. That's why you need Magisk to pass Safetynet, and that's why Magisk needs to be constantly updated.

Anyway, 'ro.secure=o' is the dumbest thing ever brought to custom roms. It's a leftover from the time, when setting ro.secure to zero would gain you root. Not anymore. But what it does do is make your system partition accessible to 3rd party apps. So, the only reason to have it is to show to the world: 'I am with stupid'.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mitchst2:
Either way this change alone allowed the apps I needed to work. Maybe won't be the case for everything but for me it's enough for now.

I still have lineageos-18.1-20210826 installed on my 6T. I would like to update to the latest version lineage-18.1-20210916.

What is the best way to do it?

1. Update lineage-18.1-20210916

2. Replace Lineage Recovery with TWRP.

3. Change to Fastboot and then do the firmware update https://wiki.lineageos.org/devices/fajita/fw_update

4. Restart and you're done.

My 6T is rooted and I made magisk hide props config because of streaming, are there any problems because of this?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] itsabrick:
For the whole process I used Lineage recovery.

1. ADB Sideload lineage-18.1-20210916 (see install instructions in lineage wiki for fajita)

2. Fastboot with Firmwareupdate like mentioned in lineageos wiki (your link)

Everythings fine so far and no data lost.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] chief_wigum:
OK that means that it is also possible with lineage-18.1-20210916. So far I have always done the update via TWRP (ROM, TWRP and then the partition in TWRP changed and restarted).

What about magisk hide props does it go with it even if that is set, that is my main concern.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] retry0001-coffee:
This message is for Eric Lev specifically.

I'm hoping you can answer me directly. I want to try to simultaneously convert my T-mobile edition to international and upgrade the vendor firmware to the latest, ideally without losing my current LOS installation. Let me step through my plan and hopefully you can give me the last bit of guidance I need to pull this off.

First, I carefully reviewed the original conversion instructions which used an OOS 9 ROM. The gist is that you are flashing img files to various partitions exactly like with the official firmware update guide. The only difference that I spot is the following partitions are additional for the Tmob to Intl conversion:

fastboot flash --slot=all boot boot.img
fastboot flash --slot=all dtbo dtbo.img
fastboot flash --slot=all system system.img
fastboot flash --slot=all vbmeta vbmeta.img

I have downloaded the latest Oxygen ROM from OnePlus and used payload extractor to get all the needed img files since the one you provide doesn't have the four additionally listed above included (for obvious reasons).

So now here is where I need your help. Am I right that I could just skip the system.img and boot.img files completely in order to not clobber my existing LOS installation? (btw I am already using the latest September ROM from LOS) I don't know what the dtbo or vbmeta images are for, but if I should skip any other images, please let me know. I realize this may not work, and I'll have to do a full clean reinstall, but I feel very close to a viable solution that will save me a lot of extra hours of tedious setup.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Eric_Lev:
Once converted to the international version, flash the needed img files by following the official procedure (skip boot, system, dbto, ... Etc).

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] retry0001-coffee:
Do you understand that I'm trying to combine the two procedures in one go and NOT override my existing installation? The procedure to convert to international is nearly identical to the procedure to update firmware to 11. The only difference is that it includes system, boot, dtbo, and vbmeta. I am wondering how important those four extra images are to the international conversion process. Boot is just the LOS recovery tool right? System is the LOS ROM itself right? If that is true, I shouldn't have to flash those at all. This merely leaves dtbo and vbmeta as the questions. Do I need to flash these to convert to international? Would it hurt my existing installation to flash them? Would I brick my phone or lock out the LOS system? vbmeta has something to do with verified boot. I don't know if it's critical or not to switch to international. I'm trying to save myself the trouble of having to do unnecessary things and reinstall my LOS setup from scratch.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Eric_Lev:
Flash the needed img files by following the official procedure (skip boot, system, dbto, ... Etc) ... without guarantee of success.

Backup your data before flashing !

Note: I am not responsible if you brick you device ....
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Saksham03:
Boot is not just the Lineage recovery it also contains other things like kernel, ramdisk for the system to boot.

I would suggest one thing dump the lineage installation zip and check what partitions it has in the zip and don't flash those partitions while converting to international.

Note: I am not responsible for bricked device
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] retry0001-coffee:
That was a good idea!

Found partitions:

boot (67 MB), dtbo (8.4 MB), system (3.0 GB), vbmeta (4.1 kB)

Aha! Precisely the partitions that differ between the international conversion procedure and the vendor firmware upgrade official instructions. So it stands to reason that the official vendor upgrade and international conversion are effectively the same. So why the huge caveat at the top of the instructions? "Warning: These instructions are NOT for carrier branded variants."
