[Q] problems with fastboot flash boot boot.img

Hi,
I'm trying to flash boot.img into my xt890 that I created following the Motorola instructions.
I compiled it and then created the boot.img using:
mkbootimg --kernel bzImage --ramdisk ramdisk.img --output boot.img
After that my boot.img size is 4.3M.
Then I run adb reboot-bootloader and I have my phone on AP fastboot flash mode (secure boot)
Then fastboot devices, works well.
But when I run fastboot flash boot boot.img I get
[email protected]:~/android/out/host/linux-x86/bin$ ./fastboot flash boot boot.img
sending 'boot' (4356 KB)...
OKAY [ 0.682s]
writing 'boot'...
FAILED (remote: Preflash validation failed)
finished. total time: 0.946s
and on the phone :
Downloading
Invalid image size for partition boot
Fastboot command failed
Any help would be greatly appreciated

Are you really really sure the twrp image is the right size?
Mauronofrio's one is exactly 81920 KB, not 98304 KB.
Also the official TWRP has the same size, AFAIK.
I would re-download it and maybe checksum it.

Why you didn't flash orangefox recovery or other twrp and then magisk via twrp?

Try to install magisk zip via twrp.
If you take magisk 22.1 only rename apk to zip and flash via twrp

Alright, so I downgraded to magisk 20.0 and I flashed it and installing the app worked, but my point still stands though :/

Question How to install custom recovery TWRP?

I searched a lot of articles all flashed to the recovery partition
Code:
>fastboot flash recovery boot_twrp_UNOFFICIAL.img
Sending 'recovery' (65536 KB) OKAY [ 2.062s]
Writing 'recovery' FAILED (remote: 'This partition doesn't exist')
fastboot: error: Command failed
I found some information that Android 11 uses Virtual A/B
Do I need to modify boot.img to install custom recovery in Android 11?

I use a type-c hub to connect a wireless mouse and it works

I used this command and it didn’t work normally, it will enter the system normally after restart
Code:
>fastboot boot images\boot_twrp_UNOFFICIAL.img
Sending 'boot.img' (65536 KB) OKAY [ 1.735s]
Booting FAILED (Status read failed (Too many links))
fastboot: error: Command failed
This command can start to TWRP but cannot install it
Code:
>fastboot flash boot_b images\boot_twrp_UNOFFICIAL.img
>fastboot set_active b
>fastboot reboot
Do I still need to unpack boot.img and copy the ramdisk file

This work for sure

This topic is great, but I'm afraid many of us would totally miss the information in here, do anyone has the will to turn the information here into a little "how to TWRP" guide as a topic here? That would be awesome!

My device is Redmi Note 10 5G China and the EEA rom flashed. Using twrp will get stuck in the logo and cannot enter.
Before that, I can start twrp using China rom. I'm still looking for reasons
----------
P.S. Does anyone know how to compile twrp for Android 11? I need a little help

i suggest for now stay on stock recovery. you can root phone installing magisk via fastboot. and the only way to try custom rom is flashing the gsi ported generic rom. the nippon gsi telefram group have a lot of gsi. but my advice is wait miu13 update. most of gsi have audio incompatibility. but if you like aosp roms this is the only way. mtk full custom roms for our device dont exist

I need some help with the recovery flashing

I am currently trying to flash TWRP to my old Xperia Z and when I try to flash it, fastboot spew me with an error:
Sending 'recovery' (15198 kB) OKAY [ 0.500s]
Writing 'recovery' FAILED (remote: 'Command not allowed')
fastboot: error: command failed
I unlocked the bootloader already and Treble Check reported that I have A-only
Can someone give me some solution to this?

The only way i got my phone to flash is by flashing it via the Sony Mobile Flasher
Dl: https://www.ytechb.com/sony-mobile-flasher/
once there unpack the RAR file
then get the fastboot and flasher drivers
and the driver for your specific model
then connect your device in fastboot mode
click the flash button (top left corner)
click fastboot mode
click flash kenel
change the explorer to search for .img files
click the TWRP img for you phone
hopefully should work
