[Huawei P20 Lite Questions & Answers] rugar:
Thanks, you've helped me allot! I've got it working and have the bootloader unlocked. Going forward, i was reading your LOS 17/18 thread. I could add a comment there but since we are writing here now, i am going to ask here:

I am still with EMUI 8. Is it actually needed to install another version of EMUI in order to install LineageOS? Isn't it possible to just install TWRP and go on from there?
[Huawei P20 Lite Questions & Answers] -Alf-:
LOS/LiR requires emui 9.1. Do not install the latest version, flash 9.1.0.200 via dload.
[Huawei P20 Lite Questions & Answers] rugar:
Finally made it and finished installing LOS. Thanks again for your help. I've marked the thread as solved.

Hi,

Has anyone been able to successfully relock their bootloader after erasing and flashing stock firmware?

The fastboot command "fastboot oem lock" returns:

"FAILED (remote: 'Command not supported in default implementation')

fastboot: error: Command failed"
[Sony Xperia 1 III] YusukeYuu:
Maybe you reboot on wrong fastboot mode, or Try use latest adb fastboot
[Sony Xperia 1 III] rasseru16:
Unfortunately I think Sony my have blocked the ability to relock the bootloader :(

I am using latest 'platform-tools_r33.0.3-windows' and I've also installed specific Sony fastboot driver from Sony Developers.

I am booting into default 'fastbootd' mode.
[Sony Xperia 1 III] Pandemic:
So this command aint work ?

fastboot oem lock
[Sony Xperia 1 III] rasseru16:
Yes that is correct, it seems that Sony have sealed up the ability to relock ourselves :(

[Sony Xperia 1 III] Sakuma_Eitarou:
maybe need to use the same serial number that you used to unlock the bootloader
[Sony Xperia 1 III] rasseru16:
How do you mean. I am using the same phone I used to unlock so the serial number should remain the same?
[Sony Xperia 1 III] Sakuma_Eitarou:
yes

if you save that number
[Sony Xperia 1 III] YusukeYuu:
Weird, my xperia 1 iii can relock
[Sony Xperia 1 III] YusukeYuu:
Try selecting reboot to bootloader first before using the command
[Sony Xperia 1 III] rasseru16:
Did you also update to Android 12 bootloader?
[Sony Xperia 1 III] YusukeYuu:
Yes
[Sony Xperia 1 III] fastbooking:
You have to reuse the code you used to unlock the bootloader, for example : fastboot oem lock C46...09
[Sony Xperia 1 III] rasseru16:
Will give that a go :)
[Sony Xperia 1 III] rasseru16:
Unfortunately, I still receive the same error, oh well I guess only Sony can repair it and relock the bootloader.

View attachment 5722325
[Sony Xperia 1 III] YusukeYuu:
You need to go on bootloader not fastbootd mode
[Sony Xperia 1 III] rasseru16:
If I select 'Reboot to bootloader' the screen is black and I need to specify which driver to install, seeing as that mode isn't fastboot I am trying to understand how it would relock the bootloader?

Thanks
[Sony Xperia 1 III] YusukeYuu:
Yes, the screen will go black, but you can use the fastboot command as long as the notification turns blue.
[Sony Xperia 1 III] rasseru16:
Ok thanks, I cannot get the notification icon to turn blue am I doing something wrong? :/
[Sony Xperia 1 III] Miustone:
You should have read my Guides.

fastboot reboot fastboot is the only command You'll need to switch between fastboot and fastbootd.

But just turn off Your Phone. Hold Volume Up and Connect USB. Blue LED and Done

fastboot oem lock

Done

Do a Software Repair with Xperia Companion after. Just liike told in My Guides. Enjoy

hi everyone.

a friend of mine recently gave me a s5 mini g800h in good condition but it's on 4.4.2. i wanted to upgrade to linageos but can't flash anything on it because of what i think may be the bootloader. whenever i enter download mode it shows the message in the title of this post and odin doesn't do anything. any advice for me?

When setting an alarm on ths stock alarm app, there is a scrolling sound when scrolling through time.

The sound is also there when the phone is on silent and vibrate (very odd).

How can i disable it?
[Samsung Galaxy S22 Ultra] raul6:
Look under settings / system sound vibration control
[Samsung Galaxy S22 Ultra] niro0070:
Maybe I wasn't clear, it's not the vibration, it's actually a sound effect of scrolling the time rollerdex that is still active even if the phone is on silent mode. Any way to disable it?

Newest security patch, backported by amazing los people, but missing at least these two backports

https://review.lineageos.org/c/LineageOS/android_external_v8/+/312152

https://review.lineageos.org/c/LineageOS/android_external_chromium-libpac/+/312150

Thats the main reason why most devs dont bump the security patch nowadays, but I did so that you can differentiate builds.

The foss build includes fdroid, fdroid-priv, microg and the aurora store.

If you use gapps flash them over the vanilla build tho.

Dirty flash from previous builds worked for me, but that doesnt mean it has to work for you.

Just a quick note:

I ran into a bootloop today, but it was easily fixable by clearing cache and dalvik. No need to format data or so.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
​

In the spirit of moving custom ROM development along for the 2019 Galaxy Tab A 10.1 [SM-T510], here's a build of LineageOS 19.1 I just created based on the latest OEM stock firmware and @AndyYan's latest LineageOS 19.1 GSI. It's very much a work in progress, but it should hopefully help blaze the trail for even more custom ROMs for this tablet.

Notes:

The current process requires you to reset to factory defaults to remove file-based encryption. Remember to backup your data!

Custom kernels are specific to OEM releases, and this one is based on the latest Android 11 release (T510XXU5CWA1).

Stock recovery will be replaced with my latest TWRP build for the SM-T510.

This is unofficial and unsupported, so the usual caveats apply. Since we don't flash the bootloader, you should be able recover from any problems...but nothing is guaranteed.

Not working:

Support for file-based encryption

Downloads:

lineage-19.1-20230403-UNOFFICIAL-T510XXU5CWA1.tar.md5 (Odin tarball)

lineage-19.1-20230403-UNOFFICIAL-T510XXU5CWA1.zip (TWRP update)

Build archives:

Android File Host

Change Log:

20230403:

Updated to LineageOS 19.1 GSI (20230323) with March 2023 security patch and GApps.

Based on the latest Android 11 OEM kernel and vendor partition (T510XXU5CWA1).

Includes TWRP v3.7.0 custom recovery built on AOSP 11.

20220918:

Initial release based on LineageOS 19.1 GSI (20220912) with Sept. 2022 security patch and GApps.

Based on the latest Android 11 OEM kernel and vendor partition (T510XXU5CVG2).

Includes TWRP v3.6.2 custom recovery built on AOSP 11.

Instructions:

From OEM stock firmware:

Unlock bootloader

Hold Vol Up & Vol Down buttons during restart to enter Download mode

Install custom ROM tarball (.tar.md5 file) to AP with Odin

If TWRP launches, factory reset with Wipe->Format Data and reboot to system. (Not necessary for incremental upgrades.)

From existing TWRP install:

Hold Power & Vol Up during restart to enter TWRP recovery

Tap Install, Install Image, select your update (.img file), and then swipe to install

Factory reset with Wipe->Format Data. (Not necessary for incremental upgrades.)

Reboot to system

Thank you dear @Magendanz very much for keeping my Old Youtube Tab Alive!

Quick Question, is an update from "lineage-18.1-20220417-UNOFFICIAL-T510XXU5CVB1.zip" to the new 19.1 Possible or do i have to update the base version first?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] NJey90:
Good evening Mr. Magendanz,

i installed this ROM on my Samsung SM-T510 and my tab/back/home buttons are not in the middle/bottom position they are in the right corner (i had this issue also with another unffocial lineage Os 19.1 Rom for SM-T510)

How can i solve this ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kenaz Rune:
Is the task bare active? I have the same layout when it is. You can turn it off in settings, but research the bar, you might want to use it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kenaz Rune:
@Magendanz , I dirty installed it over my lineageos gsi, and it works great so far. One problem I see, and had with the gsi is that I have a notification to finish installation, but there is no way to get past the network selection. There is no button to either skip or continue. Is there a way to fix this?

Thank you for this - I know how hard it is given your other responsibilities!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] galoneta:
Thanks Magendanz for this news!

Coming from LineageOS 17.1 (lineage-17.1-20200812-UNOFFICIAL-T510XXU3BTFN), what would be the sequence of steps for updating to this rom ?

Thanks.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Magendanz:
I recommend you download and install the T510XXU5CVG2 firmware, do a clean install with Odin...but intercept the restart by holding Vol Up & Down so that you reenter Download mode. Then, install this custom ROM with Odin and intercept the restart by holding Power + Vol Up to enter TWRP. From there, do a factory reset and reboot to system.

If you inadvertently miss the restart intercept and have to run through OEM setup, make sure to connect to the Internet and then enter Developer options to disarm Vaultkeeper. Don't try to flash anything else until you've verified the OEM Unlock is still on (but disabled).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] galoneta:
Thanks Magendanz for this clarifying tutorial!

So you must first always update \ have the samsung base AND the custom recovery to a MINIMUM combination set? In this case the minimum "combo" set would be a samsung rom with android 11 as base (and recovery 3.6) right ?

Will try this sequence and give feedback as soon as possible.

Thanks again.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
In the ten or so years I've been dealing with Samsung tablets and XDA, I must have seen this question asked at least a hundred times. "Can you make the wifi ROM work on the LTE version?" of whatever tablet or vice versa. And the answer is always "No." They are two different animals and normally the dev has one or the other. And it is very difficult to make a ROM for a device you don't have. And the same thing goes for tablets with the S Pen. They are NOT the same.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] dissidius:
of course mate i like your passion in explaining such things but i belive *i can be wrong of course* that i wasn't asking on a Xiaomi Poco thread..... this two devices are very much similar, smt510 twrp works correcly on smt515 for example. Just maybe the rom could also work with some little tweaks. Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Yes, TWRP can work on both but recovery doesn't access the LTE modem. And, again, I'm stating MY experience from over ten years of having people ask the question about many, many SAMSUNG tablets only.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] doctorsk:
This version of Lineage 19 already has Gapps installed. So MindtheGapps is not needed. Installing it using the tar ball and Odin means you don't need an SD card. Or have I missed something?

Do you have root?

Have you installed the corresponding firmware?

You can try to install the patched boot.img LOS20 in the other thread.

Another thing the patched boot.img will work for SmT515 ? As it is primarily for Smt5100
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] waterpolo:
What you can do is the extract the boot.img from the LOS rom. Then patch this file within Magisk app. Then you can apply the patch boot.img in TWRP.

Absolute life saver man, appreciate ya!

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DarkSteve:
Is that a thing? I didn't think the SM-T515 was supported or had much in the way of LOS development.

Is the GSI LOS 20 specifically for the 515, or the 510?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] treakeeog:
Yeah sadly the LTE version is the neglected middle child, but found that you can flash andy yen's some specific builds currently running LOS 19.1 and it runs like a gem, but I haven't test the LTE as I don't require it that much otherwise all set

Anyone ever run into the error "Only official release binaries are allowed to be flashed"?

I press and hold volume up/down to get into download mode and load up the file in ODIN (AP).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DarkSteve:
Did you follow the instructions on page 1?

The very first step is unlocking the bootloader. It took me a lot more then simply enabling dev options and unlocking it in Android. I actually had to flash a multidisabler as well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Stanleypain:
Yup it was unlocked (hence the warning on boot). I actually fixed it by flashing Stock ROM overtop of the same stock ROM, rebooting, going through initial setup again and then flashing the custom ROM.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Stanleypain:
This ROM is so much better than stock. Certain game were unplayable on Stock but I can manage with this one. Great job and thanks! :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Piricho:
I read this comment right after i had done the same thing without having the intention to try flash again. What happened to me was that i could not get the twrp recovery image (tar.md5) to flash successfully (kept getting FAIL) in odin so i flashed stock and was gonna leave it there. I just flashed recovery with a "pass" and also flashed the LineageOS from page 1 and just booted into the OS.

Hopefully this helps more people and thanks for posting this information.
