Dev, thanks for the latest update. Everything is working great. Happy New Year View attachment 6050396
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Bubble-be:
@qsnc Maybe you could post a message when there's a new build is out? Until it's official that would be the only way we would get notified.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] BlazeGarden:
So this worked without lineage-migration-signed? And does anybody know were i can find this lineage-migration-signed?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] cxantia:
Hello,

I'm not sure I understand you. This build is unsigned. After starting LineageOS there is a message that can be ignored. I didn't have to take anything into account when updating the official build.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
I upgraded from official LOS20 to this. I didn't install anything but unofficial LOS21 and MindTheGapps
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] BlazeGarden:
Thanks @Mecca EL & @cxantia. I was asking becausing in a few of the first couple of post members were talking about a key migration script. That's when I got confused. Because in the initial post this was never mentioned and there was also no reference to were to find this migration script.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] qsnc:
new release up
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
Thank you. Also, just donated. Happy New Year
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] qsnc:
ah, that was you, thank you very much for the generosity! you're already in the hall of fame :)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] FBK:
Thanks for the update and keeping my almost 6 years old device alive!

I updated directly from LOS 20 with mindthegapps and it is working great.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] christ95:
Thanks for this update, i did a clean flash of last update lineage-21.0-20240103-UNOFFICIAL-dumpling.zip

I would report a problem with screen cast, i found my fire tv stick, i click connect with it but my op5t doesn't connect, infinite connecting. Anyone have this problem? I also had this problem with LOS 20, version of December 2022

2nd question, is it possible to zoom pattern 5x5 on lock screen?

Thx in advance
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
Screen cast works perfectly, connecting directly to my Samsung TV. I'm not sure if you're device is rooted or not, or if that plays a role in connectivity, but I'm assuming that maybe your firestick is detecting your device as untrustworthy?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] christ95:
Ok so the problem is mine, thank you. My device aren't rooted, and i don't have google services, maybe is these?

Is there any way to see if the device is untrustworthy?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
There is. If you have Gapps installed, see if your device has passed Certification. It's in the Play Store settings
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] christ95:
Ah no, i don't have gapps installed, i flashed only rom. No gapps so no google services.

Edit: any workaround to bypass this certification?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
You may be able to use an app, to help. See if you can locate the apk for BubbleUPnp. There's a free but limited version available, that might help. I used to use it to stream from my phone to my TV
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ztdz:
Been rolling with this rom for 2 days now.

Had many problems, but gradually have resolved all of them.

Listing steps under the spoiler below

BE NOTED: I live in China, some of these issues unique for this region, some of them for other countries with restricted internet (Russia, Iran, etc.)

Spoiler content hidden.

Will update this post if I face other issues and resolve them
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] BlazeGarden:
Which version of TWRP did you use? This unofficial one https://xdaforums.com/t/recovery-tw...a12-cheeseburger-dumpling-11-12-2023.4351795/

It looks like it's the one with A14 support.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
With this unofficial, the kernel is 4.4. You can use any recovery that's supports 4.4 ( I'm using the last version SHRP v3.1 Beta).
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Rpbht:
Hello Dev.

Rome is excellent.

The only question is: When the LineageOS 21 officially be available?

And

Will the OnePlus 5t have official support for 21 ?

Currently It is unofficial my organisation won't support OS with unofficial tag.

If it suppose to release officially then I'll wait for it otherwise I'll have raise a request to allow unofficial OS since there is no default rooted and any mod installed.

Basically My organisation won't allow install work apps. With unofficial roms.

Thanks for such great work!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] floborg:
Does LineageOS have Screen Off gestures, like the stock OxygenOs?

By "Screen Off", I mean the gestures that let you draw shapes (O, V, ||) with the screen off to control music, the flashlight, camera, etc.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] miky10:
Hello, before installing i would like to know how is battery life on this rom compared to stock oos a10. I am asking because i tried pixel experience some months ago and was very disappointed about battery life, thanks for answers !
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] RedBandanaSissel:
I've been using it for two weeks (I come from LOS 20). Battery life is worse than OOS and comparable to LOS, although I am getting around 3.5-4.5 hours of SoT and a deep sleep drain of 1.8 %/hour.

If you want, you could root your phone, put Google services to sleep through a Magisk/KSU module, look into undervolting, etc. By doing so, I was getting around 5+ hours of SoT and a deep sleep drain of 0.7 %/hour using LOS 20 on a 6 yo battery. I'm sure I could get the same numbers on this ROM.

Bug: On another note, my Settings app force closes every time I finish using the menu to customize the LED color on my 5T, be it on the "Notification light" or "Battery light" menus. Does anyone have the same problem?

Edit: I've found a second small bug. The "Edge long swipe action" under Buttons doesn't survive a reboot.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ztdz:
could you please recommend which modules you use for deep sleep and undervolting? and some other battery saving hacks, maybe? thanks!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ztdz:
Not sure, is it possible to have light theme for Quick Settings tiles in this rom?

If not, what module can do this thing?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] floborg:
Just to clarify (because the screenshot doesn't state it explicitly), these are for when the screen is off, correct?

Also, are there options to customize the navigation bar buttons (back, home, recents) actions (long press, double tap)?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
Yes, for both questions.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] sahitha:
First of all thank you very much for keeping my 5T alive this far! Functioning is really fluid. good battery life too compared to Project Elixir A13 I was using.

2 things I miss are,

Face unlock

3 finger screenshot

I know this is off topic but there I'm having some issues with the safety net. managed to get it fixed by Magisk with Zygisk + Universal SafetyNet Fix + Shamiko. But still some banking apps says "rooted or found suspicious apps".

No expert here, but how to fix this please? any thread might help?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] RedBandanaSissel:
I use Francisco Franco's Naptime. It's not available anymore on the Play Store and was last updated on 2021 but it works fine. One of its experimental features installs a Magisk/KSU module to force Google services to be affected by Doze as well.

You can download the undervoling tool from GitHub here. Back up everything just in case and flash it on TWRP.

I also use a module called Universal GMS Doze, which may be redundant after using the previous Naptime feature, but whatever.

You could even use Franco Kernel Manager to underclock your phone just by a little bit. Makes a huge difference, but the performance impact is also noticeable.

I also disable location, all location services and Bluetooth whenever I'm not using them. Be mindful that Goolag turns some services on when location is turned on as well and they do not turn back off on their own after disabling location again.

EDIT: forgot to mention that you need root and maybe a special kernel to do this. I use a modification of the kernel from this ROM with KSU support available on the 5T's Telegram groups. DM me for more info if you need it.

SafetyNet is dead, look into Play Integrity and a module called Play Integrity NEXT.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Besuz:
When its done. ;) Please keep in mind that the people are doing this in their free time without getting paid.

Personally I think it is not that far away anymore.

You should ask the question vice versa: Will there be an official Lineage build for the 5T? Based on the current informations: probably yes.

But this might not help you with your work apps as it is still a custom rom and no official build by the manufacturer.

Hello

Os there a way to flash from lineageOS20 without wiping data? Because i am'using a Galaxy watch 5 pro and i dont want to have to erase it and reinstall thé watch app and synchronyse it too
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
Flash this in recovery. I upgraded from LOS20 to 21 without error
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ludskyrider:
Thank you Mecca EL

i will try it

But please what are the gapps tu use with this rom? google service and play store crash. Can't open google messages. Can't open google drive.Can't open chrome

And now my galaxy watch 5 pro can't connect. Any idea?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
MindTheGapps. There's an A14 version from Oct of last year that will work. Sounds like your troubles stem from the A13 gapps.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] RedBandanaSissel:
I'm using NikGapps without issues.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ludskyrider:
Ok

I am on mindnthe gapps

But with the phone apk.. it doesn 't Switch the call on HP or on the watch
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Mecca EL:
LineageOS 21 went live. Thank you OP for holding us down until now. Deeply appreciate you.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ludskyrider:
Can you share the link please ?

For waiting i change for Google phone app...
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] RedBandanaSissel:
Sure, here's the link for the different NikGapps packages for A14.

It's better now

Just a crash with paramètre / apparence et style : force close
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] j10hx40r:
It seems that with lineage os 21 recovery, we can't relock our bootloader. Doing so causes the system not to boot. I generally keep my bootloader locked in case the device gets stolen. Is this something that will be fixed in the future? Or is there any steps that are now required to have a locked bootloader?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
yeah this was working for me on lineage 20, which had signed boot and recovery imgs, perhaps the maintainer can implement signing. I dumped the certificate used to sign lineage 20 in x509 pem format, which I have attached, in case it is of any use to the maintainer to identify what key was previously being used. (serial number 97:0f:98:39:09:aa:89:49) (this will NOT help you if you are a rom user)

(note the certificate appended to boot.img in the screenshots for lineage 20 missing on lineage 21)

-----END CERTIFICATE-----
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] j10hx40r:
Nice work on spotting this. I looked into the certificate and its a CA certificate. It doesn't have the flag set to say certificate can be used for code signing. I might be wrong though as I am not that active into android space that much. I will look more into it. If its simply appended to the boot image, then probably doing the same manually might work as well. In case it was used to sign the image, well then we are out of luck. We can't really do anything about the signing if we don't have the private key. May be a new certificate might work as well. I read on reddit that oneplus 5t doesn;t really try to verify the certificate chain so creating and using a new certificate might work.

BTW: Also found this - Add BOARD_CUSTOM_BOOTIMG_MK support May be we can use this to add a custom make file that does the signing of the boot and recovery image. If I manage to fix this, I will raise a PR.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] corumuk:
Great to see LOS21 is now official. Haven't had a chance to use it extensively yet but have just finished updating and wanted to say a massive thanks for keeping this device alive and current. Much appreciated.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] mrgling:
Thank you devs for the big update, amazing you still support this device.

Updated LOS recovery and then did a dirty flash + MindTheGapps.

Feels even snappier than LOS 20. Battery time seems at least as good as before.

Only found one bug so far, when changing video resolution camera app crashes with artifacting.

Keep up the great work!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Pikoon:
Just updated from v.20, so far everything looks fine !

I flashed ROM, then GApps and finally magisk without rebooting. First boot took a bit of time (guess it's normal) but after it's all good !

Thank you guys for the great work, so nice to have this device still supported !
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] xdauser003:
awesome thanks for keeping this device updated! seems to be working, i was having problems with later versions of 20 breaking my wifi

updated from 20:

updated TWRP

used magisk to patch the newest boot.img

dirty flashed 21 + mindthegapps + magiskboot.img

reboot
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] CbrMn:
Hello, first of all I want to thank you for such a long support of our device - everything works great 😊. But the camera needs some work (or do we need to customize in the camera settings?). And increase the battery life (you can even sacrifice a bit of performance). Thanks 👍
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
For oneplus 5/t, signing with any valid certificate works, so you should be able to just generate your own new one and use that. Been a long while since I've actually done a build but if there's anything I can do to help let me know

certificate should probably be generated and kept secret by LOS/the maintainer though
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] scruffy1:
a little late to this party but...

is there any way i can back up my phone through lineage recovery before updating to the 21 install from 20?

i have been enjoying the ota updates of 20 that lineage recovery does very slickly (apart from that one dud release that needed an adb sideload shuffle), so is there a way to back up before jumping to android 14 / los 21?

i can rebuild my phone, but i am keen to minimise the effort

i presume a simple mirror of all the files will not translate back after the changed os

thanks, o gurus :unsure:
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
Others have been successful dirty flashing in #35 and #58, you could also try a seedvault backup. I'd take a full backup from a recovery if possible so you can revert to LOS 20 with all your data as if you never upgraded
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] scruffy1:
sideloaded los 21, and the mindthegapps, although it baulked at the signature (but i went ahead courageously)

all seems to work so far - does the dirty flash make mindthegapps throw that error, or have i just contaminated my phone?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
mindthegapps is not signed by lineage (because they aren't associated), so will always give that error in lineage recovery

nothing to worry about :)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] scruffy1:
many thanks for the quick reply

and so another question... the 5t refuses to send pictures via the normal text messaging ap, but has no such issue using discord or google meet (presumably because they use data)

is that a limitation of phone text transmission, or is it that i need to try and send smaller file sized pics as text attachments?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
You might need to check if MMS is correctly set up with your carrier & in your APN settings. It works for me in Google's "Messages" app, which I prefer over the stock SMS app for features like RCS. You might want to see if it works in that (or any other SMS app) to narrow down what the problem is being caused by.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] beta_serpico:
Hello guys,

thanks for this helpful forum!

I will sideload LOS 21 in the next few days.

I need some info:

1. should I use LOS recovery image or can I use TWRP 3.7.1?

2. any difference / issues using mindthegapps or nikgapps? Any suggestion on which is the best between the two?

3. Any issues with bank app (i.e. Revolut)?

Thanks.

Have a nice day!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
1. Lineage recovery

2. mindthegapps is recommended by Lineage, and works great for me

3. All bank apps and GPay are working for me with Magisk+PlayIntegrityNEXT

hope this helps

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] j10hx40r:
The boot signer tool code is still present. So it should be possible to use it in a custom makefile. Will try to come up with the same
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] beta_serpico:
Thanks a lot

Just another question: I have never used Magisk+Play integrity Next. Should I flash them without rebooting after mindthegapps? Any guide to follow?

Thanks!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:
i flashed lineage -> mindthegapps -> magisk in that order without rebooting in-between

i then installed play integritynext with magisk manager

evading root detection is off topic for this thread though, if you need further help that isn't specific to this ROM you will probably get more answers if you make a new thread

good luck!!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] quagsirus:

This is not specifically related to the LOS 21. I'm not expert but is there anyway to have Widevine L1 with the rom?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] corumuk:
Hi,

Yesterday saw a full wipe then a flash of:

lineage os 21, latest build

mind the gapps 14 arm64 (from mindthegapps.com)

All working as it should apart from google assistant.

In the google app settings under 'google assistant - hey google and voice match', it says

'Hey Google is not supported on this device.'

I've tried clearing google app data/cache and restarting, to no avail.

Any ideas would be welcomed.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] j10hx40r:
@quagsirus I tested the rom I built on my mobile today. I kept my bootloader locked for the testing. I first flashed the recovery using dd from adb root shell and then rebooted to the recovery. I noticed that there was a warning message stating I have flashed a different os, still recovery booted successfully. Then I flashed the zip file but was not able to boot from it. Bootloader complained about system being corrupted. I was still able to boot into recovery though, so I was able to flash lineage os 20 recovery by enabling ADB in recovery and then use the same to reflash lineage os 20 on the device. As I didn't unlocked the device, my data was not wiped during the process. Also as now recovery works on locked bootloader, I consider that a progress.

I have two directions to explore from here.

1) I used different key (testkey.pk8) then what was used before in lineage os 20(I believe it was verity.pk8). So one thing I will try is to use the key from LOS 20.

2) May be there is something else that needs to be signed as well?

Can you think about anything else that might be missing here?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] j10hx40r:
ok... so using verity key for signing removed the warning for when booting recovery. Normal booting still doesn't work with locked bootloader. I think I need to bring more things back.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dsandun:
I have upgraded from LOS 20 to 21. It went without any errors.

But does anyone has issue with the recent apps / task switcher? square button on the bottom of the screen doesn't work. it touches but not functioning.

Any workaround to make it work?

TIA
