Error 7 while flashing lineage-16 on redmi 3s prime

Device Information: Redmi 3S Prime - 3GB - 32GB - 6.0.1 Marshmallow
Bootloader is unlocked and phone is rooted. I used TWRP, Magisk and lazyflasher and verified with Root Checker app.
Now I am trying to install lineage-16.0-nightly-land via adb sideload and getting error as shown in the screenshot [https://imgur#com/X16jONh]. Let me know if it is not readable I will write it here.
Basically it is showing
E1001: Failed to update system image.
Updater process ended with ERROR: 7
These are the steps I have followed:
1) Unlocking bootloader this was just standard.
2) After that to root the phone I did
2.1) `fastboot flash recovery recovery.img`
2.2) `fastboot boot recovery.img`
2.3) Wiped "Wipe->Advance Wipe->Cache"
2.4) Installed "no-verity-opt-encrypt-6.1.zip" (downloaded from [https://build.nethunter#com/android-tools/no-verity-opt-encrypt/)
2.5) Got error similar to above "E1001: Failed to update system image. Updater process ended with ERROR: 7". I ignored this error and moved on to install Magisk.
2.6) Successfully Installed Magisk.
2.7) Rebooted the phone. Installed Root Checker from playstore and confirmed that the phone is rooted.
3) Flashing lineageos
3.1) Wiped "Wipe->Advance Wipe->Cache, Dalvik Cache, System, Data"
3.2) Tried installing lineageos and got error similar to above "E1001: Failed to update system image. Updater process ended with ERROR: 7"
3.3) I then tried the adb sideload method. First I checked if my device is being listed by doing `adb devices` on terminal. It was being listed.
3.4) Then I formatted the data as instructed here [https://wiki.lineageos#org/devices/land/install#installing-lineageos-from-recovery]
3.5) “Advanced”, “ADB Sideload”, then swiped to begin sideload.
3.6) Did `adb sideload lineage-16.0-20200715-nightly-land-signed.zip` and got the error as shown on the image link [https://imgur#com/X16jONh]
What should I do to resolve this error? Please Help.
Please let me know if any other detail is required.
Since I am new user, I am not allowed to post links. As a workaround I have replace .com and .org with #com and #org. Please correct them. Sorry for the trouble.

Problem rooting refurbished google Pixel 1 with magisk (failed to mount system/root)

Hi,
I just got a second hand Google Pixel 1 and I ran into some trouble trying to install magisk on it : I keep getting those two error messages in TWRP when flashing the TWRP.zip and magisk.zip :
"Failed to mount system/root (invalid argument)"
"failed to mount vendor (invalid argument)"
The two installations are still considered successful by TWRP but rebooting after flashing the magisk.zip keeps the phone in bootloop.
Any idea how I could fix this please ?
Information on the device and software used :
- android 10 installed on the phone when i got it ;
- bootloader unlocked, usb debugging on ;
- Flashing TWRP with "twrp-installer-3.4.0-0-sailfish" preloaded in the phone and the corresponding img ;
- magisk manager installed and using magisk 20.4 zip preloaded in the phone for flashing ;
- all commands made in cmd.exe from windows 10 computer ;
- adb and google drivers installation all ok.
please ask if I didn't give enough information.
Thanks in advance !

(FIXED) bootloop Pixel 4a, Magisk, Sensors, persist.img

Hello.
History.
1. I install lineage recovery
2. I install the lineage.
3. I reinstall stock (Android 11), I didn't like lineage.
4. I want to root and install Magisk.
5. I install recovery TWRP, to get the boot.img
6. I couldn't get the boot.img
7. I use the boot .img of the stock rom I installed to get the patched boot.img.
8. First start root works fine.
9. I try to make a magisk App proxy to hide it.
10. I install Youtube Vanced, I give it root permissions.
11. Reboot and bootloop.
I've tried several stock roms but none of them work, sometimes I try the simple rom, then I patch the boot with magisk because that's how I've seen in other forums that it works but it doesn't work either.
The only room that has served me has been Grapheneos, it installs has bootloop but in the end it starts, but it has no sound and no sensor, gyroscope, light etc...
I think it may be the persist.img is corrupt.
Could someone share a persist.img file that is good to install and try or any other ideas of what else I could try.
Interesting console bugs.

audio_hw_primary: out_write: sound card is not active/SSR state
The solution was like this:
1. I installed grapheneOS, which was the only OS that allowed me to start the phone.
2. I rooted with Magisk
3. Checking the log there was a persistent error and it was permissions
/mnt/vendor/persist/sensors/registry/registry (Permission denied)
4. Enter the shell with the console, (using root) and tried to change the permissions on the mnt folder to the vendor folder, but it did not allow it.
5. Create a new vendor folder with correct permissions and move all files to the new folder.
6. reboot and everything was working fine.
I hope it helps someone else.
Note: very important after making the changes in the folder run the 'sync' command

Magisk not work

As in the subject, I have a problem with the magisk on the Mi 10 Lite 5G.
I downloaded room miui_MONETGlobal_V13.0.2.0.SJIMIXM_f2b661bdf6_12.0
Due to the fact that on android 12 there is no TWRP working yet, I uploaded magisk 24.3, patched the boot.img file and uploaded via FASTBOOT, everything is loaded, I have root access but the application does not work as it should. When he wants to hide an application under the name of settings installed he gets the message: "Restore application magisk, this application cannot run as root has been lost. Please restore it to its original state." and here I have install at the bottom. after installing the application from scratch, I get another message "Your device requires additional configuration for the magisk to work properly" I click ok and I have the message "configuration failed."
I tried multiple times to patch boot.img and upload it via Fastboot but I have the same problem every time.
Anyone know the solution to this problem ???
I'm still on MIUI 12/A10, I haven't tried this out.
But - since the flash-script is just a fastboot script, you can do it a bit backwards.
Install any pre-A12-rom, after that, boot in to TWRP. Flash boot.img from the A12-rom. Then flash magisk.
Now you edit the fastboot.bat or fastboot.sh-script. Remove the line with fastboot flash boot images\boot.img. Boot in to the bootloader. Then run the script.
You should now have a fully working A12-rom with magisk.
