[Samsung Galaxy Tab A series ROMs, Kernels, Recover] LedTV1:
The tablet is unlocked, after trying to flash aboot I get a black screen. The only thing that helps is to roll back to the stock. What should I try to do? This post has my video https://xdaforums.com/t/rom-official-13-lineageos-20-0-for-the-sm-t290-gtowifi.4535635/post-88110203
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] LedTV1:
If there is anything else I can do, I would be glad for any hints
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
I know why the issue appears, only not how to fix it. Was your device shipped with Android 10 or higher? If so, this is when it happens. What the fix is, I don't know how you can fix it, but I know you can access the screen by using screen mirroring over ADB...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Ooh, you are that person in my root thread, from recently.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] LedTV1:
Yes) The device came with 10 android Okay, I won't spam any more, I'll keep an eye on the forum
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Oh yeah, no problem. I can greatly understand that you want to root the device and it does not work.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
By the way, did you try a custom ROM and see if that works? You could try it, but I don't think it works, as the pre-boot logo (first one) is not in the System partition but just built-in (I think, although it was updated when it gone from Android 9 to 10 as upgrade...), and also, it is VERY hard to get into TWRP and see in TWRP this way.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] LedTV1:
And how to flash the custom rum without installing TWRP? If I try to install TWRP or flash aboot as in this case, I always get a black screen(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Isn't it possible to use screen mirroring in TWRP???
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] LedTV1:
Does the screen mirroring work after loading android or before as well? At what point does adb start working, since mirroring through it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Not sure, need to look into that though, I saw you could edit the build.prop file and do it that way...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
I've found another bug: when my SM-T290 tablet restarts, it says it is casting to my TV, which is even off and can't be casted to. I have previously casted to this device when it REALLY was casting. But now, it's weird.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Oh no, Google apps stopped working after update..., I saw no where you needed to flash these again, also, it automatically reboots so you can't actually.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Okay thank god, reflashed it afterwards and it works again.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] tymclrewhjbcpo:
Sorry for late response. We were busy because the quakes.

I am glad that Wi-Fi problem is solved. I will clean install the latest build soon.

For second and third issues, I suppose those features aren't present in AOSP, it indicates that Samsung has modified and bloated AOSP too much for OneUI. The third issue is a feature called "Confirm PIN without tapping OK". When you set a PIN in OneUI, you can enable the feature or not. Let's suppose the PIN is 1234. If the feature is enabled and enter your PIN, your device will be unlocked as the moment you tap "4", the "OK" button is grayed out. If the feature is disabled, you'll have to tap "OK" button to enter the PIN. You can do something like entering 2653627 then deleting all and entering 1234 back, you need to tap "OK" to enter the PIN no matter what was happened. If the PIN is correct, your device will be unlocked; if incorrect, it won't.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Also, I just wanted to open a pull request for creating a README.md at the GitHub repository, but saw I can't because it is limited to collabrators. So I will post the README.md here, they can be used for both the lineage-19.1 and lineage-20.0 branches:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
You can submit to Gerrit Code Review: https://wiki.lineageos.org/contributing (it's a learning curve though. Also, do we really need a readme?)

Oh, you're around that area? Hope you're doing alright.

Tap to wake, as the LineageOS rules say, should only be added if there is support for it in the touch screen's firmware. Usually, this means the feature must be supported in the stock ROM. Hence, I asked for some clarification whether tap to wake is actually supported in Samsung's ROM, in which case I will look into it.

The third one is definitely missing in AOSP. I don't have the power to modify something that far above anyway.

I'm currently field testing the tablet at my university, and things seem to be ok-ish. We will see.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Could you or someone please fix that internal storage for SD issue? I just want to be able to install the apps there...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
How about be patient instead of constantly spamming the god damned thread? You gave me the logs already, I don't have all day to spend on developing, I have midterms next week. I already know it's a problem and I'm planning on looking at it when I actually have the time to spend. It's an SD card of all things, you can live without it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Oh sorry. I will stop about it..., will wait on you.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Oh, and one more thing: I appreciate that you made it (with others, I guess), it works very good and keeps my tablet up with new features and so. Even casting works now! It didn't on stock.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] GReddRx7:
I am having a problem. After i flashed the last rom when lineage os start i says factory data reset and restarts. Any ideas?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
@Minionguyjpro how did you format your SD card as adoptable? Mine doesn't even give me the option.

EDIT: apparently I am missing a flag to make it happen. What concerns me is that this means the option should straight up not be available. So how did you do it?

Because even Samsung disabled this on their files, as well as Android themselves really wanting to kill the feature, I am considering keeping this feature disabled.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
What version of the ROM were you on before this?

If you went from my older, unofficial builds to the official ones, then you really do need the factory reset.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] GReddRx7:
The factory rom. I will try it from the start again.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
I am on the newest version (from 14 February). And, users are already warned. If I go to insert an SD card, I have the options to format it like so:

I'm very sure it worked on stock, and YES. Sounds weird, because Samsung doesn't have the function anymore. Did it with the 'Root Essentials' app. Tried that here, but had the same problem...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Also a reminder: Looks like you did not update the changelog @lifehackerhansol, but there may be a reason?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
I don't have such an option:

If this was achieved using root, then I cannot help you. I have no obligation to fix issues that are caused by any modification to the ROM except maybe gapps.

On the topic of changelog: just use https://download.lineageos.org/gtowifi/changes/
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Oh huh, that is weird. It might be Gapps doing it, could you test that or is that like too much work to do?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
I have root, but I did not edit anything that is related to this.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
Just flashed gapps, not there either.

You mentioned you used Root Essentials, which is why I mentioned the root thing. As far as I can see, with how the device tree is set up the option should straight up not exist for you, and I plan on keeping it this way.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Yes, but that app did not really change anything.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Isn't it possible to secretly enable it, and it can only be done if the user chooses to do it using a different way? So enabling it, but not showing it or somehow. But I think you don't do so. But, is there no way to enable the internal storage SD, then??? Even not secretly? I used that to install some games there, and because the storage being not much..., well on my phone it's no problem, 128GB is enough for me, but 32GB... OR, it could be because I enabled enforce external apps in developer settings.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lifehackerhansol:
I don't recall such a secret option to do it. Not to mention, it would still involve a system edit.

I enabled force allow apps on external, and I still don't get the format as internal option.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Is there some other way to do this? Even without the system itself?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
I almost forget, but you are also the person from some Nintendo DS Homebrew stuff 😅
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
@lifehackerhansol By the way, is it normal that the owner's password is required to enter first after a reboot when you have multiple users, and shut it down while on a different user? I turned my device off while I was on a different profile from the owner/administrator profile, and I was auto set to the default owner/administrator profile when booting it on, and I could not switch profiles before entering the password for it, even though the other profiles have a password too.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Ragnak:
I took one for the community, out of despite and rage against my bad luck of finding out that I could install official LineageOS, but having the wrong bootloader version. "Let it be free or let it be bricked" I said last night.

But the bootloader fails when using ODIN. On the bootloader screen, this appears:

#SW REV CHECK FAIL <ABOOT> FUSED 4 > BINARY 3

ODIN says it failed to do anything, and the screen freezes. Powering the phone off at that point does a factory reset, and there you go.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Already expected that, as the bootloader with version 4 and higher doesn't allow flashing any custom stuff..., but now were sure.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Ragnak:
Glad to be part of the team.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] juched:
Thanks for making this. I have switched to official builds and recovery and now it updates all automatically and runs better than when I had stock... ever.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Minionguyjpro:
Nice. I only have the problem that is does not flash the addon.d stuff when updating...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] dotnano:
Soooo, I was stupid enough not to read before I update and I got the latest bootloader, too.

Is there anything one can try to get TWRP working?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 2faraway2:
Unfortunately no ... 😢
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] xinpin:
I would like to get a tablet but I don't know if it is upgradeable to android 13, can you advise me?

[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] dennon27:
Before you try anything make sure to backup all important files you have on your phone.

First you need to unlock your bootloader and unfortunately i wont be much help here 'cause i unlocked mine years ago and i don't remember much how i did it, but if i would need to start again today i would follow this guide:

installing orange fox is shown here:

just make sure that you install version of orange fox provided by Pranav Temkar and not from youtube video

And finally copy voltage-2.1-santoni-20221230-1609-OFFICIAL.zip file to the phone, boot to orange fox and follow

I got a problem after installation.

After following the above steps and rebooting, the phone shows the "Voltage" since 1h, I guess it is stuck somewhere.

Is there a possibility to see where/why it is looping?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] 0x00000bbb:
Long press action and double tap action is not working when set to screenshot.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] mateusz6768:
for some reason, it also happened to me, since it got stuck during the boot process and I tried everything from reflashing the ROM all the way to updating the miui firmware.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] alberttaucher:
No idea what is wrong with VoltageOS, but I did not see the same issue on other firmware.

I am using Havoc-OS now, the firmware installation was no problem and it runs good so far.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] stabyZep:
Logn press button when set to open custom application gets reset to default after reboot.

To hide app from launcher we have to enable app lock. It should be separated.

*Feature request - If possible make protected app's to have custom pin not the lock screen pin.

[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] paranoid_schizophrenic:
I've somehow figured it out! You have to install VoltageOS 1.8 (that was the last one that was working for me). And then, do a dirty flash of the newest version (only wipe dalvik & cache), and reboot. I hope this helped you. : )
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] mateusz6768:
still the same (it is still stuck at the boot screen when trying to boot into the os)
