[OnePlus 8 Pro Questions & Answers] Nikos2k:
I had Magisk 21.4 and tried to update to Magisk 22.0, but after a restart the phone rebooted to fastboot and does not boot to system

I downloaded the firmware from oneplus's website (11.0.4.4.IN11BA) and extracted the boot.img with the payload dumper, and flashed it through fastboot (fastboot flash boot boot.img)

But it still will not boot to system, it bootlops

Any ideas?
[OnePlus 8 Pro Questions & Answers] Nameless Foe:
Try to re flash 21.4
[OnePlus 8 Pro Questions & Answers] Nikos2k:
yes, but how?
[OnePlus 8 Pro Questions & Answers] Nameless Foe:
Are you able to boot into fastboot mode?
[OnePlus 8 Pro Questions & Answers] Nikos2k:
Yes
[OnePlus 8 Pro Questions & Answers] Nameless Foe:
Are you able to flash the older version magisk through fast boot?
[OnePlus 8 Pro Questions & Answers] Nikos2k:
Don't know how

Magisk 21.4 is a .zip file: Magisk 21.4

Is it possible to flash it through fastboot ?
[OnePlus 8 Pro Questions & Answers] Nameless Foe:
You might have to reset your phone via fastboot then flash the stock firmware
[OnePlus 8 Pro Questions & Answers] Nikos2k:
How can i reset it from fastboot?

And will I lose all my data?
[OnePlus 8 Pro Questions & Answers] wgs1028:
Did you have any luck restoring your OP8 pro? The same thing (updating from Magisk 21.4 to 22.0) soft-bricked my 8pro. I believe soft-brick is the correct term since it's in a bootloop at loading O.S.--I guess I'll try to figure out how to flash Magisk 21.4, but I've reset it through fastboot, and when I try to flash boot.img garnered through payload dumper, I keep getting messages that says I cannot flash to critical partitions. I've tried Mauronofio's all-in-one tool but keep getting flash-bat-all missing. Man I sure would appreciate any earnest suggestions. Thank you.
[OnePlus 8 Pro Questions & Answers] dlads:
Just boot the image you originally patched it with, that'll get it to boot

Then remove 22 and install 21.4

If that doesn't work then boot the stock boot image.

Magisk 22 beta causes a bootloop.
[OnePlus 8 Pro Questions & Answers] dlads:
Just use the MSM tool,, easier and risk free
[OnePlus 8 Pro Questions & Answers] Nikos2k:
I didn't manage to restore it by just flashing boot.img

I then flashed all the image files from the output of payload dumper, but it didn't work either

Then wiped userdata (by using -w switch of fastboot), still no luck

Then changed active slot and flashed all the image files to that slot, and it booted successfully
[OnePlus 8 Pro Questions & Answers] Nikos2k:
i didn't manage to successfully boot it with the stock boot.img ...
[OnePlus 8 Pro Questions & Answers] dlads:
What did you end up doing? Strictly speaking the only thing that changes should be the app and the boot image.

So fixing them should be all that's required
[OnePlus 8 Pro Questions & Answers] Nikos2k:
flashed all the images extracted from the payload dumper, to both slots, including wiping the userdata
[OnePlus 8 Pro Questions & Answers] dlads:
Then did you try safe mode

For the Oneplus 8 pro with 11.0.4.4.IN11AA I had to get a boot.img (for 11.0.4.4IN11AA) and flashed it with adb via fastboot (from PC), then my phone started up without root but still unlocked (and none of my data was lost). I reinstalled Magisk 22.0 (apk) and then put the boot.img on my sdcard and used Magisk to patch my boot.img and then i booted into fastboot and and flashed the patched boot.img via adb fastboot(from my PC). I never orginally had Magisk hidden so not sure why my phone lost root after the Magisk 22.0 update. Hopefully this helps someone onto the right path.
[OnePlus 8 Pro Questions & Answers] dlads:
Oh you installed all those images to the boot slots? Why? They need to be flashed to particular partitions AFAIK
[OnePlus 8 Pro Questions & Answers] Nikos2k:
No no, i installed them to their respective partitions

Like a total firmware reset

New updates for this version ???
[Galaxy Grand Prime Android Development] Gabboxl:
At the time I'm focused on gprime Lineage 18.1 development. I don't have much space to keep 2 Android roms at the same time on disk. Sorry.

Ok, no problem, I think it's better this way

hi I have problem .

my mobile is galaxy grand prime (SM-G530H)(HXCU) fortunave3g but i install LineageOS 17.1 (Android 10) cann't call with Sim 1 and Audio while calling not working . when i'm exit sim 2 its working
[Galaxy Grand Prime Android Development] Gabboxl:
Hello, this release is only available for gprimeltexx at the time, as specified in the rom info post.
[Galaxy Grand Prime Android Development] Scoepion110:
so i can't install android 10 ?
[Galaxy Grand Prime Android Development] Gabboxl:
This release is only for g530fz (aka gprimeltexx).

You can install 11 from here if you want, I've built it for fortunave3g also.
[Galaxy Grand Prime Android Development] aufuk1:
Hello there,

Will there be a continuation of this project?
[Galaxy Grand Prime Android Development] Gabboxl:
Hi, probably not as the development of lineage-17.1 is considered completed.
[Galaxy Grand Prime Android Development] aufuk1:
Lineage os 18.1 is running slow on my G530FZ phone, it would be great if there was 16 or 17.1 version that supports nfc :)
[Galaxy Grand Prime Android Development] Gabboxl:
This release supports NFC ;)
[Galaxy Grand Prime Android Development] aufuk1:
Yes I installed it, nfc is working :)

Only screen sharing is a bit of a problem.
[Galaxy Grand Prime Android Development] Gabboxl:
This is probably a gprime hardware problem, even when recording it lags.
[Galaxy Grand Prime Android Development] aufuk1:
I installed lineage-16.0-20200819-UNOFFICIAL-gprimeltexx and screen sharing is working. At this time, nfc is not working, each version has different agents and disadvantages.
[Galaxy Grand Prime Android Development] Gabboxl:
Well lineage-16.0 is not a rom of my creation, I don't know what its developer did.
[Galaxy Grand Prime Android Development] vitaly-zdanevich:
How can I install TWRP?
[Galaxy Grand Prime Android Development] Gabboxl:
How have to use Odin. Try googling how to, there are better guides.

[P3600 Software Upgrading] HyperMalac:
Hello There!

I've flashed my device with Alex 3.1.2 LITE rom, and I'm happy with it, but theres only one glich wich I should solve. There is no HSDPA icon on the Connections page. I mean I would like to disable the HSDPA and use it only on 3G because it saves some battery to me. On the other roms there was an icon on the connections page to disable it.

Q: Is there a registry entry for it, to manually disable the HSDPA?

P.S.: I've looked with TrinityHacks 0.3, and Schaps Advanced Config too but can't find it.

Thanks in advance,

Cheers,

For those that downloaded the March 8 build, please delete it. While it works, there was a problem with the build missing a hw video patch that I didn't notice at first. When I did a clean repo sync, I forgot to apply the hw video patch at

https://review.lineageos.org/268655

in the March 8 build. The March 8 build works as I tested it, but it wasn't until a few hours later that I realized I forgot to reapply the hw video patch.

The March 9 build includes the above hw patch. Sorry for the inconvenience.

I did notice a weird behaviour of voice match (the "ok google" service)

It keeps trying to update the voice model, shows a notification, then goes away for a bit.

Opening the voice match settings on google settings causes flickering on the window, as if it fails and restarts repeatedly. It also failed to initialize during the first boot, so I skipped it.

All other google apps seem to work fine. I've tried both Micro and Stock Gapps

New build lineage-15.1-20210313-UNOFFICIAL-flounder.zip has force encryption disabled by default.

Some people say the Nexus 9 lags over time and supposedly removing encryption improves performance. The Nexus 9 is not a daily driver for me so I don't know, but reading the older 14.1 and 15.1 threads, I decided to change the default behavior.

Since 15.1 will never be official, I changed the fstab.flounder from forceencrypt to encryptable.

/dev/block/platform/sdhci-tegra.3/by-name/UDA /data f2fs noatime,nosuid,nodev,errors=panic wait,check,latemount,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MD1
/dev/block/platform/sdhci-tegra.3/by-name/UDA /data ext4 noatime,nosuid,nodev,nomblk_io_submit,errors=panic wait,check,latemount,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MD1

If you want encryption enabled, goto settings, security and privacy, encryption and credentials, encrypt tablet and follow instructions.

If you want encryption disabled, backup all your data, goto TWRP, wipe dalvik/art cache, system, data and internal storage in TWRP. You must also format data in TWRP. Then install the March 13 build and encryption will be disabled by default. You can also change the cache and data to f2fs if you want for potentially better performance.

Going forward, all monthly security builds will have encryption disabled unless you enable it.

PS. That's the only change from the March 9 build. The above has been added to the FAQ now.
[Nexus 9 Android Development] odjinan:
bought a nexus9 yesterday, went the noob path (outdated toolkit to unlock bootloader/ root+twrp... updated twrp to 3.5.9.0) then flashed your current rom... (9march) feel smooth and nice!

thanks for continuing working on this device! its a real upgrade from my previous tab (8" tab 3).. we cant all spend money on fancy device, nexus9 is still relevant today with this nice custom rom!

edit2: stupid me of course... now build 2021.03.13 is working well without encryption problem! (was trying to remove encryption following your tutorial with the previous rom)
[Nexus 9 Android Development] philidor:
I think there is a problem with accout registration. Ok google not working but it's impossible to register some account. I try microsoft one for word. It say internet connection is not present. Maybe this can help to solve the problem
[Nexus 9 Android Development] gk1984:
Wow! Thanks for this! Since the new XDA update, it has been so awful I stopped using it. I just popped back on after 2 months away from XDA and found this rom! Going to try it soon.

One problem I had was with stadia not working. I don't mean to ask if it does now, but it does seem that the chrome browser version works now (vatrom's version). Can you at least take an educated guess if the new hardware acceleration patch in the repo might help get stadia working properly? I suspected it was either an unsupported codec or an issue with hardware acceleration being the culprit. Thanks
[Nexus 9 Android Development] retiredtab:
Never heard of stadia and I don't use google chrome browser.
[Nexus 9 Android Development] gk1984:
Google Stadia is Google's cloud gaming platform. And no, I didn't ask about Chrome. I simply was trying to ask some clarity about Lineage's hardware acceleration patch vs Barron's, but included context to my situation. I clear8 stated I wasn't exactly asking if Stadia was working, but if the new hardware acceleration patch could impact it and why.

It's pretty unprofessional to blanket statement "I don't use x" and ignore the question. It also hurts your credibility as a developer if you can't explain what's being parched into the code if you directly mention it in the OP. You could simply respond with "I'm not an experienced developer and can't articulate X or Y, I'm just capable of building from source and distributing." We don't know you, we don't know your skill level or knowledge. I'm used to ROM developers or at least those building them to know what they're working on. But your. Blanket statement suggests otherwise.
[Nexus 9 Android Development] odjinan:
back again.. and it fixed now! of course, i've downloaded the 20210309 build and couldnt figure a proper way to remove encryption on data partition... I've managed to flash gapps (use an old 16go usb key with microusb connector)..and come back to read CORRECTLY your post and understood my mistake... it was an old build!

Did a clean flash and flashed 0313 build, no more encryped data now! (flashed some nano gapps + magisk) setting up the device, so far so good!
[Nexus 9 Android Development] Quintuple:
It's great to see some people still have this tablet! They are under $50 used now, but it's a shame about stock performance...
[Nexus 9 Android Development] odjinan:
Just some personal screenshoot...
[Nexus 9 Android Development] gk1984:
I found a solution. Install the Google app from ApkMirror.com and restart the tablet. Should work after that. Looks like it's a common problem with open gapps I. General.
[Nexus 9 Android Development] kunel123:
Hey thanks for sharing your rom :)

Can I dirty flash this rom from the other lineage os 15.1 build?
[Nexus 9 Android Development] gk1984:
I'm not the developer, but I wouldn't recommend it. That usually leads to Android being unable to boot. Best to factory reset.
[Nexus 9 Android Development] philidor:
Thanks it work for me
[Nexus 9 Android Development] philidor:
I found the solution for sync with microsoft account. The problem was DNS, with google DNS no problem to sync the account

It's a problem with microsoft not related to this ROM.
[Nexus 9 Android Development] Ice Fire:
Is there no Stereo Speaker support for the device Speaker, or is my device just broken.
[Nexus 9 Android Development] retiredtab:
Define what you mean by stereo speaker? Do you mean sound coming out of the top and bottom speaker or something else?

I get sound out of both my speakers and if I download an app called "Left Right - Stereo Test" made by Reflection Apps, it identifies my left speaker as the top one and right as the bottom.
[Nexus 9 Android Development] retiredtab:
There are at least 3 other LineageOS 15.1 builds posted here on XDA over the last 2-3 years. Some use the same repositories as I and some used their own.

Even if they used the same repositories, I suspect there have been thousands of code changes so it's best to do a complete clean install to get the best possible experience. Dirty flashes tend to lead to weird problems and unproductive time chasing them down when a clean fresh install would have prevented them in the first place.

Even a dirty flash from say the March rom to the future April rom isn't a 100% guarantee that things will work perfectly. I have very little apps (only 3 that I use regularly and 4 others for testing only) on my device so it's likely to be fine for me. Someone with 30+ apps might experience problems?

Building 15.1 comprises of 700+ repositories, 85,000 files and over 1 million lines of code. The April security patches will likely need at least 5,000 to 20,000 files to be recompiled. Any code change can break something that was previously working.
[Nexus 9 Android Development] Ice Fire:
To make a long post short i had proper stereo functionality on an previews rom but now only the bottom speeaker is firing and the upper speaker which gets detected when doing a surround test is just not firing something it still did right befor upgrading.
[Nexus 9 Android Development] retiredtab:
If you haven't done a complete fresh install including format data as I wrote just earlier in post #24, try that. Do not add gapps, magisk or anything else. Then see if both speakers are working.

My speakers work fine as I get sound out of both using the March 13 rom.
[Nexus 9 Android Development] retiredtab:
What is previews rom?
[Nexus 9 Android Development] Ice Fire:
I did an absolutly clean install.

Actually lost some files i intendet to keep pver it but that happends and it wasnt to bad.

But now that you confirm that the speakers should work i will do another clean install.

And if that does not work i have an antother full display assembly ready.

Cheers
[Nexus 9 Android Development] Ice Fire:
Thats me being tired. What i meant to say the rom i used befor this, besides the speakers, nicely running rom.
[Nexus 9 Android Development] retiredtab:
Both my speakers work. I tested with music and that app I mentioned.
[Nexus 9 Android Development] retiredtab:
What app or program are you using to do a surround test? Or you just playing music and sound is not coming out of the top speaker?
[Nexus 9 Android Development] Ice Fire:
I used several different testing programs. And i tested it view a stereo test video on youtube. I know that i have two mics i know that both mics can be fired seperatly on this rom and i know that the top speaker did not fire.

I turned off audio fx, i installed and deleted viper for android to use its balance feature to push all the audio to the top mic, and i test all this in different configurations like, viper fx installed, audio fx disabled and testing with an speaker balance app called left right speaker.

I stoped when i took a look at the mixer path xml and intendet to ask here first befor comittiong to that coming weekend.
[Nexus 9 Android Development] gk1984:
May be time to do a full wipe, boot without flashing any modifications or even root, then test. I haven't had time to test my Nexus 9's audio but I will later today and make sure it's not just you. But if the developer can't replicate the issue, he can't fix it.
[Nexus 9 Android Development] gk1984:
I just confirmed both speakers are working. I played music from YouTube Music and put my ear to both speakers with relatively low volume. I have no mods and no Magisk installed. Not rooted.
[Nexus 9 Android Development] bofh999:
just a quick report.

even tough i dont use it for much (only one thing)

upgrade from 14.1 went flawless and easy.

downloaded newest twrp, gapps pico 64 for 8.1 and this rom, flashed one by one, then wiped and formated anything.

booted, restore from cloud, within a few minutes everything setup again. at least the little i need works all

(except i cannot set vibration intesity for buttons, seems to be missing in lineage)

its purely serving for touchportal but this it does very well.

and so the good old nexus 9 still serves a pupose as a soudn mixer :)

edit: one thing was wierd, when i removed google speech something both speakers made a bang, so bad i though the battery just cracked. asside from causing a heart attack i hope speakers dont get damaged
[Nexus 9 Android Development] Ice Fire:
I have completly flattedy device i deleted everything twice formatting the device and doing custom wipes of everything.

The i download a fresh bulid flashed it and it didnt work.

There is still only one speaker working.

Now if i did nothing wrong i can only try to swap my screen assembly which i bought incase the large screen would go kaputt. If that wont work i might have somehow broken my amplifier or something.
[Nexus 9 Android Development] retiredtab:
Suggestions.

1. You said the previous rom worked with your speakers. You didn't specify which one, but try the one that worked for you.

2. Try a different 15.1 rom. As I posted in another thread and before I built and shared this rom, you can try DivestOS. When I downloaded the DivestOS Feb build, it seemed more functional and stable for my purposes and than all the other previous 15.1 builds. That's when I decided to make my own LineageOS 15.1 build to see if it was stable and functional for me. After I used it for 5 or 6 days, that's when I decided to share with others.

DivestOS 15.1 for flounder has its own thread so you can check out what that rom has to offer. As I have I said, use whatever meets your requirements. I built this rom for myself, but if others find it useful, then great. If not, try another rom.

3. I'm not sure if I understand you, but if you look at this ifixit guide, the speakers don't seem to be part of the screen.

Thank you so much for your LOS build, @retiredtab. This is a very good ROM for a, uh, a floundering tablet.
[Nexus 9 Android Development] SirRGB:
Thanks for such a great rom. Newpipe in 1080p60 is very smooth, but in Netflix audio stutters after a while. I hope we still get monthly security patches, I really apreciate it.
[Nexus 9 Android Development] Ice Fire:
I downgraded to LOS 14 but that did not help me then i tried again to check if there is any hardware fault. I discovered that on the lower right corner there is a third hinge which i have missed.

After i adjusted the position of my board to accommodate all three hinges the speaker worked.

Thanks for the patience with my problem. Seems like this device has an ifixit repairability rate of 3/10 for a reason.

Hi, First of all, thanks for this great ROM. The Tablet is as fast as when I bought it.

I have only one question regarding live display. Should it work like intended or isnt it implemented overall.

It doesn't matter what i choose in "Display Mode" it won't do anything.

"Color temperature" is permanently greyed out, and "advanced" is not accessible at all.

Thanks in advance.

I'll take a look. I have an idea what might be wrong, but unsure until I actually compile it. If it can be fixed or implemented, it will be added to the April security patches which have yet to be merged into LineageOS officially as per
