Unable to flash any kernels since owning my Pixel XL

Alright guys I have never been able to flash any kernel on this phone at all. It always gets stuck on bouncing dots or sends me back to TWRP, Any suggestions? Here is how I flashed:
My steps to get TWRP + v4 Root + ElementalX v08 kernel all working together.

Followed these instructions to a T and got everything working minus the kernel but when I flash any kernel I get pushed back to recovery? For some reason I have never been able install a kernel....... Any ideas I have not been able to flash a kernel since I got this phone. Any suggestions as to why or what I could try?

I believe its
Fastboot flash boot_b or boot_a boot.img look in fastboot mode which boot slot you have a or b

fastboot flash system: partition not found

Hi All,
used my OP7T for a week before deciding to unlock. That went fine, but when I tried to flash a GSI (no custom ROMs available yet), it says partition not found?? Tried system and system_a.

Hey,
I have the same issue, did you ever find a solution?

You must unlock first

You don't say
In the meantime I found the actual solution, here it is for the record : reboot from fastboot to fastbootd using "fastboot reboot fastboot"
And then the commands will work

Can you share that recovery image?
I couldn't find it in the Rom files.

For my 600th post on XDA, I offer this info in hopes it will help.
This one is T-mobile. Don't know if it will help ort harm but it works for me.
I don't have both hands right now; yoiu'll have to search for yourself on how to enter "EDL" mode and possibly an MSM (or is it MDM?) version of stock flashable file for your model and carrier, else maybe try the T-Mobile one at your own risk: Unbrick Tool for T-Mobile
GOOD LUCK

Hi guys,

Did you find a solution ?

Download latest fastboot drivers.
From OS:
adb reboot fastboot
Or from bootloader
fastboot reboot fastboot
With devices launched on Android 10 there is a new interface called fastbootd, this is where you flash the system.

clearly. there is a difference between "old" fastboot (bootloader) and fastbootd (userspace fastboot to support dynamic partitions). You need to be in fastbootd to do most stuff nowadays.

My problem is bit different, can anybody help through this --- System partitioned doesn't exist !!!! while Gsi flashing on Realme 7 RMX2151

So when you see people posting in their tutorial;
fastboot reboot fastboot
NOW we type in;
fastboot reboot fastbootd?

No, same command, but you need stock recovery for this to work (twrp prevents fastbootd entry)

I tried for days to get to work but for TMobile follow guide on here and if it doesn't work even after you install drivers and all then use a different PC bc I have 7t and 8t OnePlus and my 8t unlocked works on my gf PC and her 7t TMobile works on mine figured that out the hard way but it's truthfully a solution when everything won't work

Unable to boot to lineage recovery

I am trying to install LOS 18.1 a Nokia 6.1 TA-1043. I have unlocked the phone and put it into download mode. Following the instructions here I then did
$fastboot flash boot lineage-18.1-20220208-recovery-PL2.img
Sending 'boot_b' (36933 KB) OKAY [ 0.958s]
Writing 'boot_b' OKAY [ 0.314s]
Finished. Total time: 1.382s
However, from there I can't get into recovery - the phone hangs at the "androidone" splash screen.
I can boot an unofficial version of TWRP with
Code:
fastboot boot
, so maybe that is the way to go.
However I would be interested in knowing whether any one has succeeded simply by following the official instructions.

Xiaomi Mi 10 Lite - Recovery mode

Dear all,
I'd like to install LineageOS on my Xiaomi Mi 10 Lite (monet).
I'm following the instructions here : https://wiki.lineageos.org/devices/monet/install.
Everything is going well until step "fastboot flash recovery <recovery_filename>.img".
I type "fastboot flash recovery <recovery_filename>.img" and everything seems to be good.
Sending 'recovery' (131072 KB) OKAY [ 4.907s]
Writing 'recovery' OKAY [ 0.571s]
Finished. Total time: 5.484s
But my phone does not power down. And when I try to reboot into the recovery mode (Volume Up + Power), the fastboot screen appears instead of recovery mode.
I also try with "fastboot boot <recovery_filename>.img".
Sending 'boot.img' (131072 KB) OKAY [ 5.044s]
Booting OKAY [ 0.154s]
Finished. Total time: 5.266s
The phone turns off and I reboot into recovery mode with success. I apply "Wipe Data" and go back to Main Menu after, as described.
But I don't find the "Apply Update" option.
Thank you for your help.

Use platform tools instead of Minimial adb and use the flash recovery command, it should work. and be careful if you need to disable
dm verity, i don't know Mi 10 Lite but yup

I downloaded and used platform tools as described in LineageOS Wiki. And then, I used windows cmd for the adb and the fastboot commands.

Use this brother: https://developer.android.com/studio/releases/platform-tools
you probably used Minimial ADB, it's the same but just use Platform tools (The one's i just sent)

You are using the wrong command bro, don't use boot. Use "fastboot flash recovery twrp_recovery.img". Why are you flashing recovery.img as boot bro?

OK guys I've found my mistake. I thought the model of my phone was Monet. But it's not. It's Toco... A stupid error showing that I have to be more rigorous.
I thank you again for your help. All the best for xda.
See you

Question TWRP Moto G20

Looking for a custom recovery I found this page where it contains a TWRP that is supposedly compatible with the Moto G20.

I did not want to risk trying it since I do not know much about this and what can happen if it is not correct. Someone to solve my doubt? or know of a compatible custom recovery? Gracias. :XX
