Soft bricked after installing kernel - OnePlus 6 Questions & Answers

I'm having some trouble guys. I got stuck in a bootloop when trying to install https://forum.xda-developers.com/oneplus-6/development/kernel-elementalx-op6-1-00-t3799054 this kernel, so I booted into TWRP and tried to flash the stock rom to fix it. However, it won't work and keeps giving me the error " Updater process failer with ERROR: 255 Error installing zip file '/sdcard/Download/OnePlus6Oxygen_22_OTA_009_all_1805172226_f7d1518e0 e704ca3.zip' ". How can I fix this? I read something about sideloading the OTA update, but it says it won't work if I'm rooted, which I am.

In you do not mind s fresh start lock your boot loder
Do NOT reboot then unlock your boot loader.
This will rest your phone back to stock.
You may have to sideload stock boot.img (maybe)
Hope this helps.

You can't flash OOS through recovery. Also since kernel only affects the boot partition, just flash stock boot and it should work.

[Q] noob -- stuck in a boot loop, tried the 2.20 unlock method.

I followed the steps from this thread:
http://forum.xda-developers.com/showthread.php?t=1952038
I successfully unlocked my phone and installed TWRP recovery, but that's as far as I can get. I tried to flash the latest CM10 nightly but hit an error when I run the zip, saying that the MD5 file is not found. I also tried to separately flash the boot.img from the CM10 zip, but it didn't help.
I've cleared my cache and factory wiped (through recovery), but I'm still stuck in the boot loop and can't get to the OS. Please help!!
I think the problem might be that I never actually rooted the phone, despite having unlocked it. Is there a way to root my phone via recovery, since I can't actually boot into it?
I tried to install RebelMod, but i hit an error saying "Unable to mount /data" -- I'm assuming that's because it's unrooted?
you want to root a stock ROM?
flash superuser downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip
update: i managed to flash RebelMod successfully (according to TWRC) by running the zip file, but I'm still stuck in the boot loop even after doing a Factory Reset thru TWRC.
am I missing something?
wait a sec -- I got it working after I flashed the boot.img with fastboot.

[Q] No Rom, failure when flashing

Hi all. I own a Moto G xt1032 UK version. (GSM right?)
I was on 4.4.4 Epsilon ROM but I wanted to flash stock 4.4.4, so I used a tutorial I found on youtube that set me up to stock 4.4.2, then I upgraded to 4.4.4 and THEN there was another update to 5.0.1. So as you can guess, I upgraded to lollipop and that was it - bootloop. I have tried flashing other roms through fastboot and nothing worked, I get an error when I flash ''system'' that says ''image is too large'' once all is done, phone restarts and its stuck on bootloop once again. The bootlogo changes when I flash different rom etc. But I don't know what to do, any ideas? :/ I have also tried to flash a custom recovery and sideload the Epsilon ROM but I only get an error in my command line that says no device connected after I hit the command. Any suggestions guys? I appreciate any sort of help, thanks guys.
I'll also add that I think I have the 41.18 bootloader if it helps (it says so in the bootloader settings)
When flashing a ROM in fastboot, are you also flashing the gpt file?
Yeah. I flash everything there's to flash as all tutorials instruct.
To try and get your phone up and running, flash a custom recovery from fastboot. Once the recovery image has been flashed, use the phone's volume buttons to boot into recovery. If you can get into recovery, try and flash a custom ROM.
Ah, I forgot to add. When I attempt to flash anything from my storage it says some sort of error coun't mount /sdcard and others when the recovery opens up. I tried flashing other recoveries, TWRP, CWM both show the exact same errors..Can't mount SDcard etc. :/ That is why I tried the sideload method which didn't work for me either.
You're flashing recovery for the falcon?
Yes..for falcon. I've done it a bunch of times before, however I never had the unable to mount error in the recovery..
I don't have my moto g on me but I found Philz Touch (based on CWM) worked besr for me after i switched back from GPE to CM12. I was getting weird error messages in TWRP.

TWRP not working

Problem:TWRP does not work. I can flash TWRP but when I boot into recovery I get stuck at the TWRP loading screen. I have used LG flash tool to go back to stock and try flash again multiple times but the same thing happens. I used fastboot to install CM13 and I have the CM recovery installed and working, but that can't flash custom kernals as that's what I want to do.
can you tell me how you restored the stock recovery
I flashed twrp recovery but when I boot to recovery I get Boot certification verify, secure booting error!, cause boot verification failed. please help I want a recovery I do not care if it is stock or twrp. I think i flashed twrp while the bootloader was locked. So how to unlock it and fix this problem.
I forgot to mention after the error the notification led goes orange , blue repeatedly. The phone boots fine.

Click to expand...
Click to collapse
I didn't restore back to stock. But if TWRP does not work u can try cyanogen mods custom recovery. for some reason that worked fine for me, or u could look for a bumped recovery as there are many of them around for the D850.

Oneplus 5 stuck on fastboot, but still have access to recovery.

Hi XDA, after searching over countless threads and not being able to find the answer i'm after here goes my first post, so the problem originated when I accidentally signed out of Snapchat and wasn't able to sign back in due to safetynet so I went about trying to unroot and reroot using Magisk, however when installing the Magisk.zip, I ran into "Error 1" which I fixed by flashing a stock boot image with "fastboot flash boot boot.img", finally the zip file "successfully" installed via TWRP but upon trying to boot my phone to OS it constantly just goes back to fastboot mode and refuses to boot properly, I still have access to TWRP and have tried flashing back to stock recovery as well to no avail. What i'm wondering is if I somehow flashed the boot improperly and that's causing it to not boot to OS and if not what else can I do to restore my phone to working order, at this point i'm not that fussed over having root access but need to know how I can fix this, I have also tried flashing a stock ROM from stock recovery but just after starting the install it and the loading bar going up slightly it stops and goes back to the file selection page. Please help!
Edit: I have flashed the boot.img again using a newer stock image and now when I attempt to boot normally I get taken to a black screen with a white LED

Bootloop

Okay I am in a situation. my Google pixel is constantly boot looping. I have tried custom roms and even stock ROMs and it keeps boot looping. I've done all the tutorials and troubleshooting threads and to no avail am I getting this to stop. My bootloader is unlocked and I cannot flash any firmware that is stock below Android 10. I thought with the unlocked bootloader you could flash almost any firmware. Does anybody have any idea on how to help me and what I could do?
After trying to flash an OTA or a factory image it keeps saying something about user data and then it says press any key to exit.
I finally fast boot twrp and sideload lineage 17.1. after flash it rebooted... usually twrp flashes and waits for you to pick reboot. Phone works but is it a matter of time before it does the bootloop again? Clicking fix bootloop recovery seemed to work.
