All,
I'm looking for suggestions on how to restore root to my Huawei MediaPad M5. I recently updated Magisk to stable Manager 8.0.7 and Magisk build 21.4. However this caused me to lose root on the tablet. The tablet is on Android 8.0.
To restore root, I tried the following steps:
1) Downloaded Huawei tablet image 8.0.0, build 200, for the SHT-W09 (C567) USA model
2) Extracted Ramdisk image and copied over to the tablet
3) Opened Magisk and selected Download and Patch File
4) Magisk patched the file and saved it in my downloads folder
5) I then transferred the patch file back to my pc
6) Opened my Fastboot folder that had the patched image
7) Booted the tablet into fastboot mode and tested with command "fastboot devices"
8) After verifying I had a connection, I typed "Fastboot flash ramdisk patched_boot.img"
9) The file was flashed to the tablet
10) I rebooted the tablet, but I still don't have root
Any ideas, do I need to use the command "fastboot flash boot magisk_patched.img"?
Thanks,
Rick
Rick,
I managed to root my CMR W09 C567 EMUI 8.0.0.200 by flashing this older version of Magisk directly within TWRP:
Release Magisk v20.4 · topjohnwu/Magisk
Miscellaneous This release is mainly focused on stability and bug squashing. Please be aware that MagiskHide is no longer enabled by default. Since Google has enabled hardware-based key attestation...
github.com
It does all the work of patching the boot file withing TWRP, and when you reboot into system, there will even be a Magisk apk already installed. Do not upgrade afterwards.
The TWRP that works for me is:
[RECOVERY][UNOFFICIAL] TWRP 3.2.2-1
This is for the Mediapad M5. NOTE: Decrypting data is not currently supported. MTP also does not work, but you can use adb to push and pull files. Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use...
forum.xda-developers.com
The command to flash:
./fastboot.exe flash recovery_ramdisk TWRP-3.2.2-1-MediapadM5.img
PS. You evidently need to have an unlocked bootloader. Mine was locked, but I managed to use the test point method and PotatoNV program. This requires removing the screen (I busted mine--had to replace from AlixExpress).

Hello zentico, is your M5 model SHT-W09?
I have a similar issue: after upgrading my SHT-W09 to latest 9.1.0.360 firmware I patched the recovery_ramdisk-image with Magisk v23.0 and it didn't boot :-(
I was able to pach the same image for recovery mode but in that case I had only limited root access. The only solution I found up to now: using the "old" patched recovery_ramdisk.image which was patched with Magisk v20.4
Edit: looks as if there are existing several C432-360 images. I got the LGRP4-OVS as this was the only version available on firmwarefinder but my device identifies as "P2" most likely that's the reason why it's not booting.

Hi!
I have the exact same tablet, but I'm unable to find the full update to patch magisk and root it fully, where/how were you able to obtain the full ota and extract the image?
Mine is SHT-W09 8.0.0.200(C567)
Thanks!

All flashing is done at your own risk!
While nothing from this thread should break your device,
don't come back here blaming anyone if it does!
Hello Guys and Girls,
the title is obvious: Here is a twrp build for the HTC U12+. I spent quite a bit of time together with the dear @Captain_Throwback to get everything working.
At this place a huge thanks to @Captain_Throwback for helping me, even though not having the device at his hands!
Instructions:
With A/B devices the command
Code:
fastboot flash recovery recovery.img
is not possible, because these devices generally don´t have a recovery partition any longer. The recovery sits now in the ramdisk of the boot.img.
So how do we get TWRP on it?
The first option is to just boot TWRP temporarily with the command
Code:
fastboot boot twrp.img
. This will just boot up TWRP, not actually flash it onto your device. After rebooting the phone, TWRP will be gone. This is a great option for those, who just like to flash their phone one time, don´t want to modify the boot.img and don´t need a permanently installed TWRP.
The second option is to use the twrp flashable installer zip to install TWRP permanently to your ramdisk from the booted TWRP or magisk manager! Installing from Magisk Manager was made possible by @osm0sis!
So you see there are generally 2 steps needed on A/B devices now.
First booting TWRP. Second flashing the installer zip.
But and now comes HTC into play. When permanently flashing TWRP zip touchscreen gets disabled, because HTC added a nasty little check into the touchscreen driver. If it detects that the phone is in recovery mode it disables the touchscreen.
Luckily we found 2 ways around that!
First way is to have a custom kernel, that has this check patched out!
Second option is to use a zip we provide here, that also patches your kernel, to avoid tripping this check. The downside of flashing this zip is that all commands like
HTML:
adb reboot recovery
, hitting reboot to recovery in magisk manager and finally reboot to recovery in TWRP are not working and only boot to the OS!
How to temporary boot TWRP:
1. You need a working fastboot and adb environment! Your device´s bootloader must be unlocked!
2. Download the twrp.img provided in this thread and copy it to your fastboot folder (pay attention that firmware version matches)
3. Open a command prompt in your fastboot folder!
3.a While your phone is booted to the OS and USB debugging is enabled, type:
Code:
adb reboot bootloader
4. You need to fastboot boot twrp currently
Code:
fastboot boot <filename of the twrp.img>
example:
Code:
fastboot boot twrp-3.2.3-2-ime.img
5. Wait for twrp to be booted
6. You´re now in TWRP
7. Please note that you need to fastboot boot the TWRP every single time you need it. After a reboot it will be gone!
8. Important:
Please note that
Code:
fastboot boot twrp.img
(like done in step 4) will also break OTA functionality. More about this in the FAQ.
How to permanently flash TWRP via the .zip installer
1. Make sure you have a working fastboot and adb environment! Your device´s bootloader must be unlocked!
2. Download the flashable TWRP installer zip provided in this thread!
2a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip
3. Flash the TWRP-Installer.Zip from the booted TWRP or Magisk Manager on your phone (hit the + while in modules section)
3a. Important: Directly afterwards flash the magisk zip from TWRP or Magisk Manager
If you don´t flash it you will only be able to reboot to TWRP, regardless of the option you choose
4.Only needed when on stock kernel without touchscreen fix:
also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
This includes
Code:
adb reboot recovery
, reboot to recovery from magisk manager and reboot to recovery from inside TWRP.
To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!
5. Reboot
6. Congratulations: you can now reboot into your permanently flashed TWRP
How to permanently flash TWRP via the TWRP.img file inside TWRP
1. Make sure you have a working fastboot and adb environment! Your device´s bootloader must be unlocked!
2. Download the twrp.img file from the offical twrp site
2a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip
3. Boot to TWRP. Navigate to Advanced -> Install Recovery Ramdisk -> Choose the twrp.img downloaded earlier. Wait for the flash to be completed successfully and do either 3a or 3b.
3a. If you want to be rooted flash the magisk.zip
3b. If you don´t want to be rooted navigate to Advanced -> Fix Recovery Bootloop to be able to boot into system
4.Only needed when on stock kernel without touchscreen fix:
also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
This includes

To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!
5. Reboot
6. Congratulations: you can now reboot into your permanently flashed TWRP
Few tips and tricks:
1. You need to mount ext_sd card before you can access it in the file manager
2. Go to mount and click on mount usb storage to access the ext sdcard when connected via USB
3. Don´t forget you can connect an usb device via usb-otg to backup/flash stuff from/to an usb storage device

Touchscreen hexpatcher | Mirror (AFH) - SEE IMPORTANT NOTES BELOW:
Only needed when on stock kernel without touchscreen fix
Flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
This includes "adb reboot recovery", reboot to recovery from Magisk Manager and reboot to recovery from inside TWRP. To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!
Known Issues:
MTP is disabled in official TWRP. This is currently an issue on several A/B devices. - Enabled since 3.2.3-1
Official TWRP can´t decrypt HTC Firmware on Android Pie!
NOTE: The unofficial TWRP image has MTP enabled for fastboot booting ONLY.
fastboot booting TWRP mounts the system RW and breaks ability to take an OTA.
Please take a look at FAQ, found in the 2nd post here. It contains more information
Bug Reporting:
If you have an issue, the first step is to post a recovery log so we can determine the cause of the issue. This is done in recovery using Advanced -> Copy Log, or adb pull /tmp/recovery.log. Once a log is uploaded we can determine how best to proceed. NOTE: Posts that are reporting bugs or issues without an accompanying recovery log will be ignored! Additionally, providing details about your device setup, including variant, firmware version, and exact steps to reproduce your issue will also be helpful in diagnosing the problem.
We need your help!

Tips on how to build TWRP for the U12+ yourself:
To build TWRP you need to use this branch as your device tree:
https://github.com/freak07/android_device_htc_ime
Additionally you these commits from gerrit to your twrp tree!
https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31760/
https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31207/
https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31021/
Depending on the base you're building for, you may need to comment/uncomment the PLATFORM_SECURITY_PATCH flag for your respective build if you want to fastboot boot the twrp.img. If the patch level of the image doesn't match the patch level of the current system, decryption will not function when fastboot booting the image. If installed via zip, the patch level doesn't matter, as it is automatically updated from system using @topjohnwu & @nkk71's resetprop.

Version Information
Status: Stable

Stable Release Date: 2020-06-22
Created 2018-07-21
Last Updated 2020-06-25
F.A.Q.:
Q: Which TWRP.img to choose for my current Security Patch State
A: For the old base 1.15 use on of the unoffical 1.15 release found in the OP.
TWRP Image 3.2.3-1.img decrypts devices, which run firmware on the 1st June Security patch State.
TWRP Image 3.2.3-2.img decrypts devices, which run firmware on the 1st September Security patch State.
The zip installer (also from the 3.2.3-2 release), however, will work on any patch level, but if you're on stock kernel, you will still need to flash the hex patcher or a custom kernel to have working touch when rebooting into recovery mode.
Q: I´m not able to fastboot boot the recovery, because the command won´t execute properly.
A: Update your adb and fastboot binaries to the latest one found here:
https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads/
Make sure you´re using the original cable.
Make sure you are in bootloader mode.
Try different USB ports on your machine.
On windows make sure you have the latest usb/mtp driver installed properly when the phone is connected in bootloader mode.
Q: I flashed the permanent twrp installer zip and now my touchscreen is not working.
A: This happens when you´re on stock kernel and did not flash the hexpatch-touchscreen zip found in the OP.
Q: I flashed the permanent twrp installer zip and the hexpatch-touchscreen zip found in the OP. Now commands/actions like
Code:
adb reboot recovery
reboot to recovery button in magisk manager
reboot to recovery button in TWRP
are only booting me straight to the OS.
A: As mentioned in the OP flashing the hexpatch-touchscreen zip will break the reboot to recovery command and associated actions.
To get to twrp reboot to bootloader and from there choose reboot to recovery with volume buttons and confirm with the power button.
Q: I flashed the permanent twrp installer zip, booted to the OS and lost root
A: Directly after flashing the twrp installer zip flash the magisk zip to keep root!
Q: I only fastboot booted TWRP but now my OTA functionality is broken.
A: Fastboot booting the twrp image trips a check, this check isn´t able to determine if system has been modified (because it receives no output) and subsequently assumes it has been modified.
this breaks verity on system and probably vendor. Resulting in non existing OTA functionality.
If you are interested in a more detailed explanation please follow this link:
https://github.com/TeamWin/Team-Win-Recovery-Project/issues/1301
to check if system has been modified check the following path:
"/sys/fs/" + Current_File_System + "/" + block + "/lifetime_write_kbytes"
Current_File_System is ext4 on the U12+
block is related to your boot_slot. so check the partition table here:
https://forum.xda-developers.com/u12-plus/how-to/guide-how-to-root-u12-magisk-tips-tricks-t3802583
if you´re on slot A: system_a is sda18
if you´re on slot B: system_b is sda19
Example:
I was on slot B so the file I needed to check was: `/sys/fs/ext4/sda19/lifetime_write_kbytes`
if this file shows 0 system was not modified. Any other value means it was modified and you will not be able to take an OTA!
Same check applied for vendor! you just have to adjust the path.
Slot A vendor: sde19
Slot B vendor: sde40
Example to check if vendor_b has been modified: /sys/fs/ext4/sde40/lifetime_write_kbytes
To restore OTA functionality follow this post:
https://forum.xda-developers.com/showpost.php?p=76606113&postcount=3
or alternatively:
1. after updating your device via RUU or OTA, patch the boot.img with magisk (look at my guide thread)
2. run the following command on either a terminal shell on the phone or via adb shell on your pc(don´t forget to grant su permissions) to obtain an untouched system.img:
dd if=/dev/block/bootdevice/by-name/system$(getprop ro.boot.slot_suffix) of=/sdcard/system.img
3. store this system.img somewhere safe
Additional info:
you can also backup vendor this way!
dd if=/dev/block/bootdevice/by-name/vendor$(getprop ro.boot.slot_suffix) of=/sdcard/vendor.img
Information: Please note that only perm s-off devices are able to flash the vendor.img in fastboot!
Q: Is there a way to restore OTA functionality and keep using TWRP?
A: Yes there is. Please read below! thanks to @osm0sis who came up with the idea!
Temporary Workaround for TWRP mounting /system as RW
the issue linked here: https://github.com/TeamWin/Team-Win-Recovery-Project/issues/1301, which is causing TWRP not being able to mount system as read-only, results in a non pristine system partition after booting TWRP once.
The following file will allow TWRP to mount system as read-only (and therefore keeping OTA functionality)
That means after the following procedure, you can restore an untouched system.img, keep TWRP flashed on your device and simultaneously be able to take OTAs!
Instructions:
1. Download the following file https://www.androidfilehost.com/?fid=1322778262904004337 and extract it! (also as attachement to this post)
2. Copy/Replace the .twrps files to
/persist (make sure to grant the correct permissions afterwards! 0664 | rw-rw-r-- )
/storage/emulated/0/TWRP
with the one you just downloaded
3. When now booting/flashing TWRP system will get mounted as read only.
4. You can now restore a pristine system.img to your device! TWRP shouldn´t mount it as RW now!
5. Check if everything worked by following the guide above (check file lifetime_kbyte_writes for your active system partition)
A huge thanks to @MassStash for testing all this!

noob question: can I format data partition and install magisk without force encryption flag like HTC 10? or is that impossible without decrypt the partition?

If you could try it and report back to confirm that would be great :highfive:
Nice work guys. Thanks @Freak07, @Captain_Throwback and all others who are still with as, as well as those who had to leave to soon - you'll be remembered.

Yes that too, just hangs at booting... It is the same procedure at the U11. You boot TWRP in Bootloader and flash from Download Mode. Fastboot is the command for both.

Not the person you replied to, but since I have the same problem, I followed the steps in OP, and since it's only 2 steps, I'm sure the other person performed the "adb reboot bootloader" step.
Ah, Ok. Interesting, it worked the first time for me, have you tried redownloading the TWRP img and trying it again? If so, then it may be a problem specific to your device, in which case @Freak07 should be able to help you out better

Try both bootloader and download mode for booting. Although only bootloader should work for booting.
Make sure you have the latest fastboot and adb drivers!
Try different usb ports.

Low and behold after updating the binaries twice and redownloading TWRP.img for the third time, it finally booted to TWRP. Cancelled decrypt and kept "Read Only". Flashed your Kernel successfully except for preload error due to not mounted. Rebooted and everything seems good, shows Kirisakura_1.0.
Thanks for the help!
Hello,
i'm trying to root a Sharp B10 (SH-A01) with Magisk.
It would be nice if i could do this without unlocking because i want to keep the stock rom anyway.
First problem is that i can't find a custom recovery (TWRP, CWM) for this device from where i could install Magisk.
Then i found out that Magisk gives the possibility to root a device through the Magisk Manager App by patching the boot.img.
But the second problem is that i can't find the boot.img either. I spotted the boot partition on the device and tried to pull with adb but i would need an already rooted device to give the needed permissions.
Is there anything else I could do to get this thing rooted besides compiling my own TWRP for the device?
thanks a lot,
paul

Neither Magisk nor TWRP is needed to root Android: Chainfire's SuperSu does the job. You flash its ZIP via stock recovery "adb sideload"

Hi,
thanks for your answer.
I already managed to root this device. I got the boot.img with Wwr_MTK & SP flash tool (windows tools...), patched it with the magisk app and than flashed the patched boot.img
1. Unlock your bootloader enter in download mode Vol+ + Vol- + USB conected to pc (Keep in mind that by doing this you will lose your files, it is advisable to make a backup of your photos, music, etc.)
2. Once you start your cell phone install magisk manager, Choosing the boot.img file of your rom into the app (Tip: Only!!! If your model is SM-A015M Android 11 I leave you my own modified boot.img to flash:
File on MEGA
mega.nz
Otherwise, you can download the firmware (3.79 gb) and extract the boot.img from the firmware of your model SM-A015 M / F ... Android 10, Android 11... etc. And No need for pc
https://samfrew.com/model/SM-A015M/
3. The image will begin to flash
4. When it restarts you will have Root on the cell phone!
------------------------------------------------------------------------------------------------------------------------------------------------
Extra: If you need the custom recovery I give you the link with my TWRP which is installed through the Odin program on a PC (this step does not delete your files)
File on MEGA
mega.nz
Keep in mind that to install TWRP you must deactivate the DM-VERITY & FORCEENCRYPT DISABLER I leave it in a link:
Zackptg5 - Android
zackptg5.com
This is a module that can be installed via magisk, which is necessary to decrypt the system ... so once TWRP is installed, it is advisable to uninstall it via Magisk to avoid R / W errors
I have flashed latest android 10 to my A3 and mistakenly uninstalled TWRP. Now i want to install twrp recovery. But everytime I flash it in partition b, it get stuck on fastboot screen.
If twrp doesn't support Android 10 then how come it supports other Android 10 based custom rom like Pixel Experience?
Because those custom ROMs use android 9 vendor, boot etc
Thanks for your helpful response
Sapper Morton said:
TWRP itself is compatible with Android 10, but not the pre-built image; the non-bootable state could be explained by the Pie Kernel inside twrp.img from official TeamWin website. Nonetheless, you can use Magisk to patch the Q boot image, or just download and flash the attached file, it's a v11.0.8.0 QFQMIXM boot image patched with the latest TWRP:

Thank you for your helpful response. If i want to flash twrp permanently, which zip file i need to flash after booting it temporarily with your attached twrp.img?
Sapper Morton said:
You must always use TWRP Installer (there's no need in specific custom ROMs, since they provide built-in custom recovery), the image I attached can only be used to install temporarily in Android 10 firmware (other than 11.0.8.0 QFQMIXM). And remember, all of this could be avoided if Xiaomi had implemented the boot command into Mi A3 bootloader:
Code:
fastboot boot image_example.img

so i am guessing there is no way to add the boot command to fastboot

Hi!
Thanks a lot, where I can find the file for the v11.0.11.0, or at least can you specify how I do this using stock boot?
Thanks! Hope to hear you back.
I booted with patched boot and finally was able to enter into TWRP recovery, but then I erased system/data/dalvik and tried to flash Pixel Experience but I am always getting error 1 when doing it. What can I do? It is something about the Android Q base? I'm now on build 11.0.11

means that with this twrp it is used only to open the twrp periodically, once the custom rom is installed I install the twrp normally

Thanks you saved me. I could boot into recovery with your boot.img but the encryption failed. Nevertheless I could sideload the recovery.zip to the device and install on both slots.
Hi all, my first post here.
I recently bought this phone thinking it was customizable. Every tutorial I have tried has failed and required a re-flash to stock ROM using MIFlash.
I have tried custom ROMs, GSI ROMs, 64 bit, 32 bit, etc. I tried using Magisk 21.0 to root, it appears to work, but I believe the boot.img patching isn't currently working on this particular phone.
Most tutorials I have tried are very simple and use TWRP to flash the OS img file, then reboot and enjoy. Some suggest flashing vbmeta.img to prevent boot loop, but, boot loop happens anyway. I have TWRP installed and working, so far, that is all I have had success with.
Can this phone still be customized at all?
Update: I achieved root on the stock ROM. If anyone is interested I'll post the exact instructions.

Your bootloader needs to be unlocked and USB debugging enabled first of course. TWRP Recovery should be installed.
To do this, you need the adb and fastboot binaries installed on a PC/Laptop. I use Ubuntu and installing these is trivial via apt package manager:
Debian based:
Code:
sudo apt install adb fastboot
RedHat based:
Code:
yum install adb fastboot
If you use Windows, the install and use of these binaries is a little different. I don't use Windows so you'll have to do a quick search to find out how to install and use these binaries. The commands listed below will work no matter what OS you use.
Connect your phone to your PC/Laptop via it's USB cable and reboot it to TWRP Recovery:
Power off the phone, then power on while holding the volume up button until you see the TWRP logo. Log into TWRP to decrypt.
Next, you need to pull the current boot.img from your ROM to patch it for root access:
Code:
adb shell dd if=/dev/block/by-name/boot of=/sdcard/boot.img
There should be a boot.img on your phone's internal storage, copy it to your PC/Laptop. From TWRP, reboot your phone to fastboot.
Now, we'll use this most excellent, free resource to patch the boot.img file which will give root access:
https://patcher.yaalex.xyz/
Check the 'Include Magisk' checkbox on the website before submitting image.
Important: After you upload your boot.img file to the website, be patient. This could take 10 minutes or more to complete, just wait until you get a prompt to download the patched image. You will be provided a patched_boot.img file from the website once it is finished.
Finally, all you need to do is flash the patched_boot.img to your phone:
Code:
fastboot flash boot patched_boot.img
Boot your phone to the ROM:
Code:
fastboot reboot
Install Magisk Manager if you haven't already, and enable Magisk Hide in the settings. Magisk Manager should report root access is available and SafetyNet test should pass.
I typed all this up from memory so if you run into trouble or are confused by any step, let me know and I will gladly clarify/fix the steps.
I hope this helps others achieve root on this phone. Let me know how it goes and happy de-bloating!
Rollback instructions:
If your phone fails to boot don't panic. You can restore your original boot.img if needed to regain access. Reboot your phone to fastboot:
Boot phone while holding the down volume button until you see the fastboot logo.
Next, flash the original boot.img to the boot partition:
Code:
fastboot flash boot boot.img
Now just reboot to ROM and all should be restored:
Code:
fastboot reboot

Iirc redmi 8a is an ab device, and yes this device is as customisable as any other Qualcomm. What gsi image are you flashing?
Actually he is not way off ..... i am NOT able to find a Custom Non MIUI ROM with full VoLTE support. VoLTE fix for GSI's ( if at all it worked ! ) does not work for Havoc. twrp root is all good. I want a NON MIUI ROM that can regional variants ( Europe and Asia ) and supports VoLTE
Good evening dear members, I ask for your kind advice, as I have done something wrong to my Oneplus 5t.
I upgraded my Oneplus 5t with "lineage for microG" 19.1 (from lineage 18).
I had installed TWRP 3.5.0_9 (phone encrypted).
It booted fine the first time into system.
The problem arose after I tried to install Magisk 21.4 from TWRP.
Now the phone only boots in recovery, but it doesn't enter TWRP's menu. It stays on the first TWRP screen (where it shows the version number).
The good thing (I hope) is that I can enter fastboot mode.
I tried flashing TWRP again from fastboot to no avail.
I tried flashing boot.img from fastboot (taken from the original firmware), but still no luck.
Is there a way to install the original firmware from fastboot?
I think starting from scratch would be a step into the right direction.
Please give any suggestion which I fill follow to the letter.
Thank you, thank you, thank you!
You have to be decrypted or flash DMverity for A12. I assume You mean Magisk 24.1 the current version is 24.3
Hi. This is what I did:
I downloaded and installed original firmware through fastboot (fastboot was still on).
I also installed original recovery through fastboot.
After that my oneplus 5t was in stock condition, apart from the bootloader, which was unlocked.
After that I managed to install TWRP through fastboot, and then lineage 19.
The thing is that TWRP doesn't support lineage 19, for one reason or another. Or it could be the other way around (lineage 19 doesn't support TWRP). In any case I had a phone which would only go in fastboot mode.
At least I knew what to do, as I did it already: reinstall stock firmware and recovery.
Long story short, I installed LOS recovery and lineage 19, and everything works fine.
Thanks everyone, and especially thaidroid, for the support.
Have a nice day.

What recovery are you on? TWRP?
I use the one posted alongside each version: https://download.lineageos.org/dumpling
can you help?
I need to root so I can titanium backup everything. but I can't root. I suspect I might need to fully format and wipe and start again, I tried wiping data and doing a fresh install, but after sideloading magisk it just fails to boot every time now.
Does it boot regularly BEFORE installing magisk? I am trying to define the source of the problem.
I have installed lineage 19 and magisk, and I confirm you that it's possible
Yes. It boots fine if I just install lineage then nevermindthegapps. problem only occurs if I flash magisk. I tried installing the .apk and patching the .boot image manually in it and then fastboot flashing that, but same thing.
oh - one possible thing that it may be - is that I had a couple of modules loaded (I think a gcam fix mod and something similar) in magisk, and I read somewhere about people having them stuck 'installed' despite demoving all traces of magisk app. whether that is the problem I don't know.
This is very strange. That's what I did:
Sideload lineage recovery
Sideload lineage 19
Download magisk apk
Patched boot image from lineage 19.zip
Sideload the patched boot image
And that's it it all worked
May I suggest you to start all over again?
is wiping system data sufficient or do I need to format it? I'd rather not lose my appdata- but I can't rescue it without root / titanium backup :/
Try first without formatting, and see how it goes
I wiped system/cache, installed lineage-19.1-20220719-nightly-dumpling-signed.zip / mindthegapps, phone booted up fine - rebooted fine.
ok, good. Now download latest magisk app and patch the boot img.
do I click patch vbmeta in image?
Yes.
First extract the file called boot.img from lineage.zip you just installed.
Then in magisk select "patch vbmeta in image".
Magisk should produce a file named something like " magisk_pached-24300_f41h3.img".
That patched file should be sideloaded.
Installation is explained really well by topjohnwu
it wouldn't flash without selecting vbmeta, so tried with, flashed it, now i'm sitting looking at the boot logo.
