I downloaded the m-kernel zip a75 (lollipop 5.1.1) and flashed it through cwm. It reported a successful flash. I rebooted and it went to the google screen, then the boot screen, and then.......... the horrid optimizing apps screen! So, I waited for the apps to be optimized, and then it reported starting apps. The window closed and I expected it to boot but up but instead met by a brief NFC thing failure message and the device went back to the bootscreen and started doing everything over and over again. Please help! I really don't want to reset my device! Why isn't it working and what should I do?
youre beat. i did the same thing. the kernel does not work with 5.1.1 so unless you TOOK A BACKUP BEFORE FLASHING there is nothing you can do but reset.
you can try reflashing the rom without wiping the data partition, or restoring only the BOOT partition from backup. it will work, thats what i did until they get the kernel situation figured out. youre not the first to encounter this.
I was running xXx 4.5, and decided to "upgrade" to 5.0.
I did the usual, wiped data/system, then flashed.
I got stuck in a bootloop, and found I had to double back and wipe /data.
I did that, got stuck at the boot animation.
If I go back to recovery, all the data is jumbled, I assume encrypted? I flashed a different twrp for 8.0 compatibility, no change.
I can't push/sideload anything (roms, recovery zips sideload fine), it fails.
So I flashed the stock recovery in fastboot, rebooted there, and tried to sideload via adb the stock 8.0 flash files.
Now it works at it for a few minutes and just comes back as "Installation Failed".
Where do I go next? All i can get to is recovery, fastboot, bootloader.
I've already factory reset/wiped everything, so don't care if I lose anything anymore.
Help?
Thanks.
It appears I found a solution, just a few posts below my own! I hate it when that happens.
Anyways ,
https://forum.xda-developers.com/showpost.php?p=75364805&postcount=7
seems to have got the ball rolling, I was able to copy files to my phone while in twrp, which I couldn't do before, and currently have xXx installing. The first time it installed it didn't ask about encrypted/decrypted and didn't give me any warnings, this time it did.
xXx still won't boot after flashing, trying stock full flash file..
edit 2: Was able to flash full oneplus update file and boot. had to do a factory reset after rebooting as it was crashing a ton and wouldn't get through setup. It's been running fine since though. Now I'm a little skittish to try again, there are some root features I'd really like to still have.
I have a OnePlus 5 phone stuck in the Fastboot mode, been contacting them for days now but I still keep hearing the same excuses that the matter has been escalated to their tier 2 tech support team Nd would be contacted. Please is there a way to copy files off the phone in this state before it's flashed?
Sorry I'm on mobile! Poor formating and typing is all my fault
So I'm out of my mind trying to fix and find a guide to fix my issues. This is how it all started
I was running the latest magisk (20.1) and OOS (9.0.17), when I installed Vance through magisk. I didn't read the instructions all the way, so I installed the module, it worked, then I saw that you can uninstall the YouTube system apk then install Vance. I deleted the Vance on my next reboot AND uninstalled YouTube system app, and I got stuck rebooting my phone. I have TWRP installed on my phone, not flashed (I didn't know the issues with TWRP when I installed the zip through TWRP). When it got stuck booting, I flashed magisk Uninstaller and it fixed the issue. I tried to reinstall magisk 20.1, and I got the same issue, stuck at boot. So I was able to go home, and use the oneplus 6t manager found here on the forums, which roots with magisk 18.0, and, it worked! But I couldn't update to the new magisk without it freezing my boot. After some deliberation on it, I decided to wipe my phone to try and fix it, and TWRP was still installed, and all my issues still persisted. After this setback, I found fastboot rom also on xda, and got it working, did an Ota to 9.0.17 from 9.0.16. Everything was working, until I went into my recovery and it wiped my phone. I don't even know where to go from here and I need help. Any and all help would be appreciated!
Edit: I just local upgraded to android 10 oos, and it seems to be fine. I don't know yet fully because I'm not at my house!
Hello everybody.
Twice I tried to install LineageOS 18 on my 6T, equipped with latest OxygenOS/Android 11 version, without any success despite having followed several tutorials on Youtube and on websites.
Two days ago I unlocked the bootloader, I restarted the phone from the PC in Fastboot mode and I tried to install the TWRP recovery, always getting an error and when it seemed that I had succeeded the phone restarted showing the message "Qualcomm Crashdump" and the phone was dead.
Fortunately, a Wipe Data from the Recovery allowed me to get the 6T working again.
Last night I tried again by installing the LineageOS recovery first, I restarted the phone and I realized that it was in bootloop.
At this point I could only restart it in Recovery or Fastboot mode, without being able to start the 6T correctly; not even a wipe data helped me.
At that point I used the MSM download Tool, with which I was able to reinstall OxygenOS v9.xx and restart the 6T, then updating it to OxygenOS 11.
The drawback now is that when I turn on the phone it takes over a minute to boot (the two dots around the OnePlus symbol make a good 37 laps, after which the phone starts up and works perfectly).
How can I fix this slow boot problem?
And why has it become so difficult to install a custom ROM on the 6T? It occurs to me that OnePlus has deliberately complicated things to hinder modding.

Did you get twrp installed? Wipe data by typing yes after flashing?

You can follow this. If you want to install lineage os and want Google service make sure follow the "non gapp version" under installation method.
Havoc Flashing Notes for OnePlus 6 /6T from OOS 11 [Using TWRP Recovery]
1. Clean Flash : 2. Dirty Flash 3. Update oos base 1. Clean Flash : 🔊 Make sure you've backed up whatever data you want to keep to somewhere that's not on your phone; we're going to format the data partition and you're going to lose everything from internal storage. Basic requirements ○...

Thanks for replies.
I must add this point: my 6T has OxygenOS v11.1.1.1; maybe this the reason of the problem? Maybe OnePlus did something that screws any modding attempt?
I simply followed the instructions found on YouTube, in the LineageOS' Fajita page and installed TWRP, but my 6T went in "Qualcomm Crashdump" and TWRP was not working → phone bricked.
Then I've tried installing, in the same way via ADB and Fastoot commands the Lineage Recovery, that has worked but when I tried to boot system, keeping OxygenOS, the phone went in bootloop.
So where is the error/fault?
Please, help me with a step-by-step tutorial that lead me to successfully install TWRP and LineageOS on my 6T.

OnePlus definitely didn't do anything to make it harder. You need to fastboot boot twrp.img then flash the twrp installer zip. I'll attach both In next post. Reboot to recovery. Then install OOS, twrp installer, reboot to recovery. Install oos again, twrp installer again, reboot to recovery. Now install lineage, twrp installer, reboot to recovery. Install lineage again, twrp installer again, reboot to recovery. Factory reset and wipe data by typing yes. Boot to system
The img is for fastboot boot
The zip is for installing in twrp
Thanks for your reply.
I'm still wondering how to speed up the boot.

If everything is installed correctly it won't take long to boot

There is clearly something wrong, as my 6T's boot is slow.
Furthermore, the Recovery of the previous message is the one I downloaded three days ago and that made me go to the 6T in Qualcomm Crashdump.
I repeat my request: where can I find a safe and updated guide that explains how to install LineageOS without risk?
If you can't fastboot boot into that twrp on a11 without crash dumping there is something really wrong

You sure you didn't try 3.6.0_9?
Clearing your cache might help with current boot. But once you install a new os everything will run smooth like it should
Thank you for the advice.
1) I've downloaded "twrp-3.6.0_9-0-fajita.img" and tried to install it several times, getting errors and then bricking my phone.
2) I have already cleared the cache several times from Recovery, without anything having changed; the two white dots on the boot screen continue to rotate 37 times around the red dot before the phone starts up and then works perfectly.
It occurred to me that the MSM Download Tool program uses a decrypted image of the original firmware; could this possibly be the cause of the long boot?

That twrp version always will crash dump on a11. Use the one I sent
I followed these steps:
after having managed to make MSM Download Tool detect the phone in EDL mode, I proceeded by reinstalling OOS v9.0.13, after which I reconfigured the phone and restored the apps backup stored in my Google account.
Later, I don't remember the details well, I received the update notification for OOS v10 and later for OOs v11.1.2.2.
I don't remember exactly where the boot started to stretch, however this is more or less the process I followed to bring my 6T back to life.

Are you sure that this TWRP will work without problems?
I've tried also with Lineage Recovery for Fajita, resulting with the 6T in bootloop :-(

I promise it works. I do t know what happened with your previous updating and msm tool but something sounds messed up. Just get twrp running and ease all your problems. Clean flashing and getting everything fresh

Keep your finger crossed...
Another question: assuming I can install TWRP and make it working, LineageOS image must be copied in the 6T's internal SD and proceeding to install from TWRP?

Or you could use USB OTG. Or a PC and use adb sideload
