Accidentally flashed a kernel to the recovery - Lenovo ZUK Z2 (Plus) Questions & Answers

So I was flashing a new TWRP, and I accidentally flashed a kernel I had in my downloads folder onto my recovery partition. I reflashed TWRP, and got the phone to boot, but every time I try to skip the "device is unlocked" screen, I get part of an error screen that the device can't boot as if it's zoomed in. If I don't try skipping the screen it will boot, but I feel the error is indicative of other problems.

Can't wipe/edit data patition

I finally flashed a non Sense ROM onto my dev edition M8, and now I can't even touch /data. I got the enter password to decrypt storage bug while using Paranoid Android, so I followed the steps here to get back to a working system, but the ROM never booted to the password screen. It froze on the boot animation, the went in a loop, I tried to wipe data through recovery, the screen went blank after a few seconds, and then tried to boot the system again. I can't get it to wipe via fastboot either as I get a "FAILED (remote: not allowed)" when trying erasing and formatting data/userdata. I also can't delete anything from /data in recovery. Does anyone have a fix for this? Flashing other ROMs also suddenly quit and go back to trying to boot the system.
Edit: Flashing a stock recovery to wipe /data fixed it. Why didn't I think about that sooner?

Does not boot. Corrupted /data parition?

Hello,
my Samsung Galaxy S4 mini with bliss ROM stated to turn off spontaneously and sometimes it didn't start again (the Samsung logo appeared and then the phone went dead, it was impossible to enter recovery mode, download mode shut down itself immediately). After several tries, it booted normally. This happened again - and I found out it was a bad power button, which I replaced. Now it is possible to enter both recovery mode and download mode with no problems. However the main OS doesn't boot up. So I tried to do a full wipe in recovery mode and CWM recovery rebooted the phone, when it was trying to format /data partition. So I tried to flash stock firmware with ODIN. It also didn't boot up, but at least the stock recovery gave me a hint what is wrong. When I perform full wipe, I get error: "E:format_volume: make_extf4fs failed on /dev/block/platform/msm_sdcc.1/by-name/userdata"
I tried to flash the phone again, this time with a PIT file and let ODIN to reformat the partitions. However, no change. How can I fix it?
Try twrp

problem after updating rom/soft-bricked?

So I was updating six rom and phone went into continuous boot. So went into recovery and wiped all but internal memory and reinstalled. Same boot problem. Went into fast boot and pushed another over as well as a vendor image. Tried installing the new rom, beans gaps, super su and same result. I've left the phone for over 20 mins with no result but the boot screen.
I'm having a similar problem.
My status- Unlocked bootloader, twrp accessible, devices not getting detected in fastboot mode by the pc, rooted, restoring using the backup results in a bootloop, correct drivers installed on the pc, superSU and full backup in the mobile.
i cant transfer files since device not getting detected.
my timeline- i followed every instruction on https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930 and everything went successful, but when it rebooted to the 'Welcome' page (the page which comes when u open mobile for the first time) i restarted my nexus 5x 32gb to recovery mode and then the every boot procedure doesn't complete for several minutes(doesn't go ahead the ball animation)

My device screen keep black does not get on (I change the twrp to slot 2)

So, what happened, I was almost finishing the flashing of the rom, I was in twrp, and selected reboot to boot loader mode, but I selected slot 2; then my screen never more get on. @majmoz Can you help me?
there should be a error screen after boot with slot2, coz i was tried before, i fixed with full flash with gpt / bootloader with full rom

Question Failed to load/authenticate boot image

Good Day All, I've seen a few thread regarding this but nothing stating what causes it to happen. Can anyone provide any insight?
I was about to perform a reflash of my rom but didn't even reach that far.
I restarted phone to recovery
Was going flash a firmware before the rom flash but decided to switch from slot a to b cuz i wasn't sure if the firmware is a global thing or per slot
Changed slots and restarted to recovery
Noticed no prompt for decryption key and my data/media was gone.
Changed slots again without doing anything and restarted (TWRP prompted no OS found)
After the recovery started again no prompt for decryption key again and no data
Figured twrp loaded badly or something. Restarted to recovery one more time
Phone did not boot to recovery. Keep bootlooping to fastboot
Attempted to reflash TWRP when I encounted the error "Failed to load/authenticate boot image"
After a quick google the solution seemed to be the flash over the stock rom via miflash and start over which I unfortunately did
While the solution worked. Does anyone have any clue why this might've happened so I can avoid it in the future? I don't think the Rom matters but I was running Arrow-v12.1-alioth-OFFICIAL-20220819-VANILLA.zip and the recommended firmware V13.0.4.0.SKHMIXM
