Download the apropriate .img file for device. A/B. If that doesn't fix the problem then it is something with the TWRP, I'v been getting does error too. You are not the only one.

[Samsung Galaxy A12] DandyFug:
Hi I'm kinda new to this. So I followed your guide on unlocking the bootloader and rooting. I've also installed TWRP, no problems at all. Now I'm trying to install LineageOS to my phone, I don't have an external SD Card so I couldn't do method 1, I went to try method 2 which is through ADB sideload. If I don't start sideload on my phone it is detected by "adb devices", but when I start sideload on my phone it disappears from "adb devices" and I can't sideload the lineageos file into it(Tried on both my Linux and Windows system). I still don't know much so I tried playing around with it, I used "adb push" to put the lineageos file into the device and it worked, I can click on it in "Install Image" but in the install image screen I don't see "System Image" as a choice. I'm just wondering if there's anything I did that was wrong?
[Samsung Galaxy A12] LAST_krypton:
Probably bugs with TWRP, I had problems with ADB SIDELOAD too, dev should fix them soon. If you don't see SYSTEM_IMAGE then flash DynaPatch to allow flashing to DYNAMIC_PARTITIONS in RECVOERY. You can find DynaPatch here, and you can ask about SIDELOAD problems...

[Samsung Galaxy A12] chechumaru:
When I try to install Lineage OS with method 1, TWRP asks partition to flash image:

Boot, Recovery, Optics Image, Prism Image or Super.

Which one should I use?
[Samsung Galaxy A12] LAST_krypton:
Flash dynapatch to allow flashing on dynamic partitions in recovery, then you will see system_image where you want to flash on.

Flashing on SUPER woun't work because of READ_ONLY restrictions thats why you need to flash dynapatch.
[Samsung Galaxy A12] chechumaru:
Thank you so much!!!! Lineage OS installed at least!!!!

[Samsung Galaxy A12] uluruman:
I have, using my script. I am still searching for a more straightforward way, there were a lot of efforts from physwizz but currenty the main goal (i.e. flashing .img directly into the dynamic system partition) seems still has not been achieved.

I have lineageos recoevry installed on my SM-930F. How do I flash TWRP. My USB to computer connection does not work. Can I flash from lineageos recovery using the microSD card?
[Samsung Galaxy A12] matahbeyz:
@aarem Try to boot into Download mode by shutting down the phone and then connecting it to the PC and holding down volume up and volume down.
[Samsung Galaxy A12] aarem:
@matabeyz, the link over USB does not work for me, sorry. Therefore, i have to try and use SD card if it is possible to do.
[Samsung Galaxy A12] matahbeyz:
@aarem Hmm, do you have TWRP or something like this? Also try a new cable
[Samsung Galaxy A12] aarem:
No, it is not a cable issue, it is some fault in some devices, in this cases herolte. TWRP used to be installed but a LOS update last year wiped it out, and so I need to reinstall. So, I am trying to understand how to install it without adb or through LOS recovery.
[Samsung Galaxy A12] matahbeyz:
@aarem Without ADB is really hard, I don't know if it will even work
[Samsung Galaxy A12] hd_scania:
And @edward0181 ’s TWRP flashes IMG GSI’s pretty good, but doesn’t flashes ZIP’s like SUperSU and independent GApps at all, even when in TWRP terminal shell unzip command exists, every turns ZIP’s are being flashed, ZIP files themselves (only other than DynaPatch) report unzip command missing, and hence his TWRP is ‘‘a bad recovery’’, i’m pretty puzzled

Also manually mounting system, vendor, product, and ODM partitions never works, even when DynaPatch has been every turns flashed first, they still aren’t mounted at all
[Samsung Galaxy A12] geocamus:
Hello, I have the SM-A127M.

I have been able to do the following:

1.Unlock the Bootloader.✅

2. Root with Magisk.✅

But I want to follow this Guide to install LineageOS and I have the following questions:

1. Is it possible to install LineageOS on SM-A127M?

2. Is there a version of TWRP for Android 11 on the SM-A127M? Download a version to install with Odin as AP from here: https://eu.dl.twrp.me/a12/

But the only thing it did was go into an infinite loop in Download mode. Lucky that I was able to unbrick it by flashing the full firmware.

3. Is the reason for switching to LineageOS to improve the phone's performance, do those who already have it really feel an improvement in performance or is it the same as using it with Stock Android from Samsung?

Thank you for your answers.
[Samsung Galaxy A12] LAST_krypton:
You can find all information related to RECOVERIS for all types of this phone on the forum here:

https://xdaforums.com/t/quick-start...threads-root-twrp-kernels-guides-etc.4355735/

In my opinion Linage GSI is better than stock, but haven't yet done any tests to give you a satisfying answer. You have to apply that this is GSI rom, not a ROM based on the phones firmware. GSIs are generic system image, which are cross compatible because they are based on AOSP. A ROM designed for specific hardware will always be better then a generic image.
[Samsung Galaxy A12] geocamus:
Thanks for your answer. I had already seen the "Quick Start Guide" but it doesn't mention anything regarding TWRP on this phone. I followed the other guide but it gave me the bootloop error in recovery.

If it is GSI, I would still like to test it to see how it behaves and any improvements to this phone are welcome.
[Samsung Galaxy A12] LAST_krypton:
Oh sorry, I read it wrong. You mentioned the M model, I red it like F. Excuse me. You might be able to get physwizz or Afaneh92 to build it for that firmware, OR cross flash to the F.

[Samsung Galaxy A12] Sharktruck:
I can't boot into TWRP. I have followed both this guide and the previous one about rooting and bootloader, the only difference being in the previous guide my phone wiped after I unlocked the bootloader. Phone model is SM-A127F/DSN

[Samsung Galaxy A12] LAST_krypton:

[Samsung Galaxy A12] LAST_krypton:
Ofcourse treble check will fail because you have dm-verify disabled and also is running a non stable magisk image.

[Samsung Galaxy A12] Hidden User:
Not necessarily. But if you have root you can use the app on the Play Store to install TWRP.
[Samsung Galaxy A12] ru_vlad1:
I feel like I'm doing something wrong

I booted into download mode, I flashed TWRP, I hold volume down and power for 7 seconds until the phone turns off, and immediately press volume up and power

Yet I just can't boot into TWRP

It just always boots normally

I'm 100% sure that I got the right TWRP image and I'm 100% sure I'm following the instructions correctly

Is it because I'm on Android 12?

Edit: For some reason I can install TWRP only if I root my phone first

This guide suggests you need a rooted phone to install TWRP. My understanding is that it's possible to install TWRP and flash Lineage (or whatever custom ROM) without rooting the phone?
[Samsung Galaxy A12] reyukisan:
What happens if I skip the wipe step and directly flash the custom rom? I do that and encounter bootloop, but I have no idea why the wipe is necessary or why bootloop occurs as a result.

I don't want to wipe my internal storage for some reason
[Samsung Galaxy A12] uluruman:
In the 90% of cases the bootloop is a crude way of the OS telling you "incompatible existing data found". The newly installed system tries to read and, if possible, upgrade the existing files on the data partition, and if it does not know how to deal with it (e.g. if they are from a newer version of Android) it dumps the error info into the debug console (if one is connected) and reboots.

When I am trying to connect my HUAWEI MatePad with Harmony Os, I can only connect it as a phone, but it does not work to activate multiple screens, acoordding on the tablet, due to Bluetooth problems, although I do have it activated.

I can't find my tablet from the tablet connection section and Huawei Share doesn't work either. I don't understand why. Does anyone have the answer?

Thanks in advance :)
[Huawei P40 Pro Themes, Apps, and Mods] Narex2004:
Also, could you tell me what's your Pc's Bluetooth version? I started thinking that mine is probably too older and that's why PC Manager doesn't work completely fine for me.

I'm using Asus Strix GL503 and Huawei p40 pro, i think it's not about your Bluetooth driver.

For tablet it's required other things, I still trying to see what's make PC manager split connection for phone and tablet.

With older PC manager (original thread), can you connect PC manager with matepad?

I don't have matepad so I can't try it myself.

Can you see version.dll if you install original PC manager (from Huawei website) ?

If there's version.dll you can try this version.
[Huawei P40 Pro Themes, Apps, and Mods] Narex2004:
I tried connecting my Matepad with the older version of PC Manager through QR code, but in that version, I get an error in the Navigator App.

With the last version I can connect my Phone and Matepad with the QR code, but I can't use the multiple screens function. From my tablet I have the option to enable it, but when I try it, it shows a Bluetooth error. In the other hand, when I try the Matepad connection I simply don't see my device

Also, I don't have NFC in my PC. My USB Bluetooth memory is version 4.0 and Im using an ethernet cable for internet connection.

I have downloaded and installed the official latest version (11.1.1.101), and there wasn't any version.dll file into the PC Manager directory, so I simply copy the file from the older version of the app (from the original thread).

I'd like to know a couple of things:

Is the Multiple Screens function working for you in your Huawei P40 Pro? And can you use Huawei Share effectively?
