[Android Q&A, Help & Troubleshooting] Foufure:
After extensive research and numerous trials, I've been attempting to root my device using a series of steps involving the MTKclient tool and Magisk, but I've hit a couple of roadblocks.

Here is a summary of the process that I've followed and the issues I've encountered:

Retrieving the boot_a.img File: Initially, I used the MTKclient tool (MTKclient on GitHub) to extract the boot_a.img file successfully.

Patching with Magisk: Next, I patched the boot_a.img file using the Magisk application (Magisk on GitHub).

Flashing the Patched File: I then attempted to flash the patched boot_a.img using fastboot and MTKclient. However, upon rebooting, there were no changes, and the device did not have root access.

Attempting to Flash with Empty vbmeta: As an alternative, I tried flashing plus an empty vbmeta, but this resulted in a bootloop.

Advanced Method - Flashing and Resigning vbmeta: Finally, I attempted a more advanced method that involved flashing vbmeta and then resigning all the files together, following guidance from this resource. This approach prevented the bootloop, but I still couldn't achieve root access.

When I try patching boot_b, Magisk reports an error, which similarly occurs with init_boot_a and init_boot_b.

If I flash both boot_a and boot_b with the Magisk patch, the device boots correctly but without any errors or root access.Has anyone encountered similar problems or does anyone have suggestions on what steps I might be missing or need to adjust?

To anyone who has installed this: how is your experience, any issues, battery life, etc.? Also, did you flash over LOS20 or did you go back to OOS prior to install of LOS21?

Thank you!

Edit: flashes straight over LOS20. No issues. Battery is great, even better than before! in2017
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] mednazim:
I have it installed on my phone now evolution x 8.3 but I want to share with you this rom .... everyone says that it is very stable in many phones..This weekend I will try it and tell you
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] returnedinformation:
I've had OOS and was waiting for an official LOS21 release to finally flash my first custom ROM

I have a couple of issues:

1. is the one issue I've already reported, I had to "factory reset" my phone after enabling Ambient Display because I just couldn't make it work again. Thankfully I've had decent backup of everything so wasn't an issue, just a time waste

2. I couldn't get Google Pay/Wallet to work, it always recognizes it as a device of no suficient security standards or whatever. Might be a skill issue, but I did manage to get the Basic integrity and CTS profile a Pass. Thankfully, Revolut and my banking app do work when properly excluded from all the root stuff, though Revolut face identification seems a little buggy, but with persistent tries it finally works.

3. There's an issue where the phone changes the brightness for a little tiny bit when switching from 60Hz to 90Hz and back... I've solved this by enabling "Force peak refresh rate" option in developer options, and I prefer that option nevertheless

Everything else is great, it works so much faster and better than the OOS and I gained 20-30GB of free space which is definitely not a bad thing for a 128GB device. I dare to say it's already even more stable than OOS because I had weird bugs with OOS

Battery life for me is approximately same, but I do have some background services running like Syncthing, VoIP client and GadgetBridge. I never really had to charge it before going to sleep after unplugging it in the morning.

For me, following the official LineageOS instructions worked like a charm, I had the latest version of OOS13 (IN2013_13.1.0.585(EX01)), so I wouldn't know how it differs when having older versions or other custom ROMs
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] shinn82:
hey there, thank you for this update. I am currently using this as my primary driver and so far so good, except one thing:

I was wondering if it is possible to remove the preexisting build-in apps from the rom (after rooting)?

for example I wish to remove the "browser" and use the play store's mozilla as my primary.

I tried removing them with titanium backup however I could not because a message "cannot locate apk" kept popping up I am not sure if that is a rom thing or android version thing or even a titanium thing hence my question here.

(EDIT) also the camera has a "watermark" thing going on and there is no apparent way of turning that off although I do not know if that is as intended.

thank you,
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] shinn82:
have you kept the rooting on at all times? I ask because I did that, and some apps (bank, sim's app and pokemongo (of all things)) refused to work with hidden/bypassing root and had to uninstall it.
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] returnedinformation:
I've installed Magisk, renamed it/hided it, installed modded Universal Safety Net fix by kdrag0n through Magisk, installed Shamiko through Magisk, enabled Zygisk in Magisk options, DISABLED DenyList but still added Revolut, banking apps and other apps which shouldn't find the root in "Configure DenyList" because apparently Shamiko uses that list
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] shinn82:
cool, thank you for the clarification.

in my case unfortunately I could not remove the default apps with rooted apps (titanium/ remove system etc) so I un-rooted the rom... I have not found a way to remove default apps that actually works on android 13/14...

Hello,

I have been experiencing issues with Galaxy Watch 4 Bluetooth connection after the previous update released some time mid April. Once the watch loses BT connection, it doesn't reconnect. After I reset the watch, it connects to the phone, however, once it loses BT connection, it cannot reconnect. There are solutions on different forums regarding this but none of them works.

I did some digging and the problem seems to be related to BT driver. Any idea how to fix this?

Same issue. I've been trying to figure out what was going on, as well. I've just turned off bluetooth for time being on my watch.
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] rsansev:
Same here!

It's been over a week since I (and others) have submitted bugs and there's been no fix!

Here's latest:

Connecting to Bluetooth devices only rarely works after upgrade (#7097) · Issues · LineageOS / issues / android · GitLab

Expected Behavior Bluetooth devices such as a Pebble Time Steel watch should work correctly.

Have you switched to another ROM, if so, which one?
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] BRANDENDEUCE:
I haven't switched. It's not an enormous problem if I keep Wi-Fi turned on and Bluetooth off on the watch. Some functionality is limited, but I plan on waiting it out.
[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] rsansev:
Do you know of any way to contact the devs?

Not only do they not appear to be tracking the bugs, they are also ignoring PRs!

Fellow affected user posted:

"Issues opened for this get locked by the LOS team and the reversion which would fix it was marked abandoned last month.

https://review.lineageos.org/c/LineageOS/android_packages_modules_Bluetooth/+/389135"

It appears the only hope we have is that it is fixed in QPR3 and LOS merges it.

Hi all, does anyone perhaps know of ANY way at all to "fool" Samsung apps into installing on SM-G955F with LOS 21 installed? It seems that LOS21 "identifies" as Pixel (I think LOL) so I would like, if possible, to get it to "identify" as a proper S8+. Maybe a Magisk module, like the one for Google Wear?

Hi all!

I have custom Android 13 (not LOS) on my Oneplus 8. I don't remember, which official Android version was installed before. I.e., some partitions content may be inherited from even older versions of Android.

So, can I directly flash LOS 21?

Or should I flash some special official Oxigen OS version before to update some secondary partitions with radio module HW and others?

1. Download the latest oos stock firmware from here. https://github.com/Wishmasterflo/Firmware_flasher?tab=readme-ov-file

2. boot to bootloader mode.

3. Flash Los recovery: fast oot flash recovery los-recovery.img

[OnePlus 8 ROMs, Kernels, Recoveries, & Other Devel] Dmad007:
I've installed it on my OP8. Some things are good, the latest OS is a nice and clean refresh of the relatively dated device. Battery life seems good.

Some ISSUES that I note, and kindly ask if they could be addressed in the next updates:

1. Sound volume is rather low on both loudspeakers and earpieces. Volume needs to mostly be kept at maximum level to get a decent level of sound. Can it be fixed?

2. Irritating issue with Auto-Screen-Brightness.

I have activated the constant 90hz in developer options as I also had the "blinking issue" that is noted above.

However still there is another issue with the screen brightness that varies inconsistently and randomly, not reflecting the actual level of ambient light accurately as it was on the original ROM. Seems quite buggy as on occasions the screen would blink from brighter to dimmer, on one occasion the brightness slider did not work at all. The biggest issue is the inaccurate performance and the frequent auto-changes of screen brightness. Wish it was gradual and smooth, actually and in line with the environment in which it is used.

Can you please look at that and fix it as well ?

3. Camera shutter has a huge lag. Can you port the original CAM app, or is there a Pixel camera or another one that you can recommend to work well. I downloaded the Pixel camera from the play store, but it is buggy and for some reason does not work well.

[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] DaveImagery:
Hi all. I've been wondering for months, why either my tablet S6 or my tablet S7+ would not connect to my smart tv. Both devices see each other, they are both on the same wifi network, but when attempting to connect, it initializes, and then drops off. I have been on the phone with Samsung's Smartview dept (yes it's a real department) nothing we have tried works. They are officially "baffled" and can offer no further support. Well it finally occurred to me, perhaps it is because my tablets are all rooted? Hmmm........ Well as it turns out, yes, that is the culprit. I was able to easily confirm this by first attempting to connect with my new Galaxy Tab S9 stock out of the box, works perfectly, connected no problem. I then tried that same tablet again after rooting, and no connection. Does anyone know how I can still make the tablet connect to my smart tv, while rooted? Many thanks.
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] blackhawk:
Try this.

If that fails do some more general Gookill searches with that title; it doesn't have to be the same model or firmware.

Most Samsung issues go back many years.

Samsung tech support is almost always a waste of time🤣 Occasionally you get a smart one though.
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] DaveImagery:
Many thanks good sir! That solved the problem. Who new? lol :)
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] DaveImagery:
Oops may have spoke too soon. Doesn't seem survive a restart :(
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] blackhawk:
You're looking in the right spot. Why doesn't it survive reboot? Possibly the security level of your version? Keep playing with it until you find a workaround...

I have zero experience with rooted Androids. One reason being I have Snapdragon's and another is troubleshooting them is more straightforward albeit less diagnostic tools and options. However if I didn't block a bunch of system apps and bloatware it be a complete and unusable power hog.
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] DaveImagery:
Yeah it works fine till reboot. I'm assuming even with root access that file cannot be edited. I see others recommending MagiskHidePropsConf but I haven't the slightest clue how the helps. Nothings easy I suppose. :(
[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] DaveImagery:
Well I guess for now I can just flash it in terminal as needed. It's not like the tablet gets rebooted all that often. A perm solution would be nice though.

It's a sad state for the marble custom rom community; most roms get 1-2 updates then get dropped.

There are very few roms with continuous support from their devs. EvoX, PA, CrD are the only ones that come to mind.
[Samsung Galaxy A53 5G] mytja:
Greetings, XDA and fellow Galaxy A53 users!

This will most likely only work on SM-A536B (Exynos models). I cannot really test others, but I can tell you approximately what other files you need to copy.

With the help of @smiley9000, I've successfully ported his SMS fix module from Mediatek to Exynos. It works by rolling back the RIL to a previous firmware version. Many users of European models have reported existent SMS fix modules as not working on GSIs after OneUI 6 update, including myself. It turns out that European models are a tad more complicated and need a bunch of other files inside the Magisk modules. By installing this module, SMS receiving should start working.

SMS sending is as of day of writing this dependent on your GSI. A patch for sending on Android 14 has recently been implemented, but it still isn't in all GSIs.

You do NOT need this module if you're running firmware from June 2023 (A536BXXU6CWE9) or before.

Module is attached below. It requires Magisk or KernelSU.

Again, all thanks go to @smiley9000 (smily9000 on Telegram) for his massive contribution and @IverCoder for the initial fix.

Source code:

Please report all issues here or on the GitHub page

-----------------------

Changelog:

v1.2: Initial release

Added files from A536BXXU6CWE9 (EUX) firmware. SW rev 6.

-----------------------

Disclaimer:

I am not responsible for any damage caused.

P. S.

Currently this module is pretty scuffed up and probably includes way too many files. But it works. I'll try to remove some in future releases and locate the point of failure.

[Samsung Galaxy A53 5G] mytja:
Just if anybody stumbles upon this. DO NOT USE AFANEH's kernel. It is considered legacy and might not boot on newer firmwares, on which this SMS bug is present.

I recommend ExynosUnbound, it's been working very well per my testing.
[Samsung Galaxy A53 5G] mistral11:
do you need to flash this with Magisk or can be done from custom recovery (fastboot?)
[Samsung Galaxy A53 5G] mytja:
Magisk (and perhaps KernelSU) will do. I haven't tested a flash from TWRP. It might work, it might not, idk.

[Samsung Galaxy A53 5G] SnootyInk:
First of all, I wanna say that this works even on the S22 on LineageOs20.

My problem is that after uninstalling magisk messaging will stop working again even if the files remain in place. I cannot keep my phone rooted as my banking app doesnt allow this. Thank you very much!
[Samsung Galaxy A53 5G] mytja:
Magisk or KernelSU have to be kept in place. It can't just be uninstalled, as this module only replaces files in memory. It doesn't actually replace the files in internal memory.

If your banking app doesn't allow it, check DenyList in Magisk settings. Enable it, as well as Play Integrity Fix module, and it should work. If it doesn't, then the banking app contains strong security checks, and likely checks for an unlocked bootloader, which is unfortunate, as you'd need to revert back to stock in that case.

Another possibility might be making RW vendor, although I can't really help there, and I'm not sure if it'd even work by doing so. In theory it wouldn't anymore require Magisk root.
[Samsung Galaxy A53 5G] oslavq:
Consider using shamiko magisk module to hide root from banking apps.

Enable zygisk in magisk settings, install shamiko module and add your banking apps to denylist in magisk settings, and reboot. Let me know if it helps
